The recent sea star die-off throughout the eastern Pacific, known as Sea Star Wasting Disease, has prompted a need to understand spatial and temporal patterns of sea star assemblages and the environmental variables that structure these assemblages. We examined spatial and temporal patterns in sea star assemblages (composition and density) across regions in the northern Gulf of Alaska and assessed the role of seven static environmental variables (distance to freshwater inputs, tidewater glacial presence, exposure to wave action, fetch, beach slope, substrate composition, and tidal range) in influencing sea star assemblage structure before and after sea star declines. Environmental variables correlated with sea star distribution can serve as proxies to environmental stressors, such as desiccation, attachment, and wave action. Intertidal sea star surveys were conducted annually from 2005 to 2018 at five sites in each of four regions that were between 100 and 420 km apart across the northern Gulf of Alaska. In the pre-disease years, assemblages were different among regions, correlated mostly to tidewater glacier presence, fetch, and tidal range. The assemblages after wasting disease were different from those before the event with lower diversity and lower density. In addition to these declines, the disease manifested itself at different times across the northern Gulf of Alaska and did not impact all species uniformly across sites. Post sea star wasting, there was a shift in the environmental variables that correlated with sea star structure, resulting in sea star assemblages being highly correlated with slope, fetch, and tidal range. In essence, sea star wasting disease resulted in a shift in the sea star assemblage that is now correlating with a slightly different combination of environmental variables. Understanding the delicate interplay of environmental variables that influence sea star assemblages could expand knowledge of the habitat preferences and tolerance ranges of important and relatively unstudied species within the northern Gulf of Alaska.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jembe.2019.151209","usgsCitation":"Konar, B., Mitchell, T.J., Iken, K., Dean, T., Esler, D., Lindeberg, M., Pister, B., and Weitzman, B., 2019, Wasting disease and static environmental variables drive sea star assemblages in the northern Gulf of Alaska: Journal of Experimental Marine Biology and Ecology, v. 520, p. 1-10, https://doi.org/10.1016/j.jembe.2019.151209.","productDescription":"151209, 10 p.","startPage":"1","endPage":"10","ipdsId":"IP-107631","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":372418,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Northern Gulf of Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -154.62158203125,\n              57.28498092462365\n            ],\n            [\n              -145.535888671875,\n              57.28498092462365\n            ],\n            [\n              -145.535888671875,\n              61.554109444927185\n            ],\n            [\n              -154.62158203125,\n              61.554109444927185\n            ],\n            [\n              -154.62158203125,\n              57.28498092462365\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"520","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Konar, Brenda","contributorId":131034,"corporation":false,"usgs":false,"family":"Konar","given":"Brenda","affiliations":[{"id":7211,"text":"University of Alaska, Fairbanks","active":true,"usgs":false}],"preferred":false,"id":782618,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mitchell, Timothy J.","contributorId":222573,"corporation":false,"usgs":false,"family":"Mitchell","given":"Timothy","email":"","middleInitial":"J.","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":true,"id":782619,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Iken, K.","contributorId":178282,"corporation":false,"usgs":false,"family":"Iken","given":"K.","affiliations":[],"preferred":false,"id":782620,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dean, Thomas","contributorId":140481,"corporation":false,"usgs":false,"family":"Dean","given":"Thomas","affiliations":[{"id":13512,"text":"Coastal Resources Inc., Carlsbad, CA","active":true,"usgs":false}],"preferred":false,"id":782621,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Esler, Daniel 0000-0001-5501-4555 desler@usgs.gov","orcid":"https://orcid.org/0000-0001-5501-4555","contributorId":5465,"corporation":false,"usgs":true,"family":"Esler","given":"Daniel","email":"desler@usgs.gov","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":12437,"text":"Simon Fraser University, Centre for Wildlife Ecology","active":true,"usgs":false}],"preferred":true,"id":782622,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lindeberg, Mandy","contributorId":195895,"corporation":false,"usgs":false,"family":"Lindeberg","given":"Mandy","email":"","affiliations":[],"preferred":false,"id":782623,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pister, Benjamin","contributorId":219669,"corporation":false,"usgs":false,"family":"Pister","given":"Benjamin","email":"","affiliations":[{"id":40046,"text":"Ocean Alaska Science and Learning Center, National Park Service","active":true,"usgs":false}],"preferred":false,"id":782624,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Weitzman, Ben P. 0000-0001-7559-3654 bweitzman@usgs.gov","orcid":"https://orcid.org/0000-0001-7559-3654","contributorId":5123,"corporation":false,"usgs":true,"family":"Weitzman","given":"Ben P.","email":"bweitzman@usgs.gov","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":782625,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

The Arctic cod (</span><i>Boreogadus saida</i><span>) is a circumpolar species and is a vital species in Arctic food webs. To examine population genetic structure of Arctic cod at macro- and micro-geographic scales, we characterized variation at mitochondrial DNA (mtDNA) and microsatellite loci among Arctic cod located in the Chukchi and Beaufort seas in Alaska. We found two distinct mtDNA haplotype clusters, although there was no underlying geographic pattern (</span><i>F</i><sub>ST</sub><span>&nbsp;= −0.001). Congruent with this finding, microsatellite loci suggested a panmictic population (</span><i>F</i><sub>ST</sub><span>&nbsp;= 0.001) across northern Alaskan marine waters at a large spatial scale. However, we found slight but significant micro-geographic partitioning of genetic variation in the southern shelf of the Beaufort Sea that appeared to be associated with the western reaches of the Mackenzie River plume. This fine-scale spatial pattern was not associated with kin-associated groups, suggesting larvae cohorts are not remaining together throughout development. We hypothesize that this pattern reflects the intermixing of Pacific and Arctic origin lineages of Arctic cod.</span></p>","language":"English","publisher":"Oxford Uni.

Climatic changes drive increased export of terrestrial OC into many aquatic networks, yet the role that circumpolar lakes play in mineralizing this carbon is unclear. Here we directly evaluate ecosystem-scale OC cycling for lakes of interior Alaska. This arid, low-relief lake landscape is representative of over a quarter of total northern circumpolar lake area, but is greatly under-represented in current studies. Contrary to projections based on work in other regions, the studied lakes had a negligible role in mineralizing terrestrial carbon; they received little OC from ancient permafrost soils, and had small net contribution to the watershed carbon balance. Instead, most lakes recycled large quantities of internally derived carbon fixed from atmospheric CO</span><sub>2</sub><span>, underscoring their importance as critical sites for material and energy provision to regional food webs.

This map product series, named “US Topo,” is modeled on the now historical USGS 7.5-minute (1:24,000 scale) topographic map series produced and printed by the USGS from 1947 to 2006. US Topo maps have the same extent, scale, and general layout as the historical topographic maps. US Topo maps incorporate an orthorectified image (hereinafter referred to as “orthoimage”) and shaded relief image along with a selection of data that were included in the historical 7.5-minute topographic maps. Between June and September of 2017, the USGS transitioned the format of US Topo maps to be published, by using a geospatial extension, in an International Organization for Standardization (ISO) 32000-compliant Adobe® portable document format (PDF) that is called a “geospatial PDF.” Previously, US Topo maps were published, by using geospatial extensions patented by TerraGo® Technologies, in PDF in a format called a “GeoPDF®.” The geospatial PDF design allows a user to zoom in and out in a georeferenced environment, turn layers on and off, view or print any combination of layers, and print any portion of the map at the published scale.</p><p>US Topo maps are intended to serve conventional map users by providing geographic information system (GIS) information in symbolized form in the customary topographic map layout. The maps are not intended for advanced GIS analysis applications. These products are built on standard coordinate systems and include full U.S. National Grid (USNG) lines, making US Topo maps particularly useful for emergency first-response operations. These maps are also used by traditional topographic map users, such as resource managers, planners, and recreational users who continue to have a need for the symbolized feature data contained in the 7.5-minute quadrangle maps.</p><p>Full-size style sheet templates in PDF defining the placement of map elements, marginalia, and font sizes and styles accompany this standard. US Topo maps published as geospatial PDFs are fashioned to conform to these style sheets so that a user can print out a map at the 1:24,000, 1:25,000, or 1:20,000 scale using the dimensions of the traditional standard 7.5-minute quadrangle. Symbology and type specifications for feature content and detailed requirements for geospatial content will be published separately.</p>This document is an update of the US Topo Product Standard published in 2011 (Cooley and others, 2011).

Melting of Arctic sea ice is causing polar bears (<i>Ursus maritimus</i>) of the Southern Beaufort Sea (SBS) to increasingly spend summer on land, where they may encounter novel pathogens. Here, we tested whether SBS polar bears on shore during summer exhibited greater immune system activity than bears remaining on the sea ice. In addition, we tested whether the type of immune response correlated with body condition, because adaptive responses (slowly-developing defenses against specific pathogens) often require less energy than innate responses (rapid defenses not based on pathogen identity). After accounting for body condition, we found that polar bears on shore exhibited higher total white blood cell counts, neutrophils, and monocytes than bears on the ice, suggesting greater infections. Lymphocytes, eosinophils, basophils and globulins did not differ. C-reactive protein, an indicator of inflammation, also did not differ between habitats. Body condition was associated with variables indicative of both innate and adaptive immunity, suggesting that neither response was uniquely limited by energy resources. Our data indicate that as more polar bears spend longer periods of time on shore, they may experience more infections. We encourage continued health monitoring of this species and studies of the long-term fitness consequences from disease.</p>","language":"English","publisher":"University of Chicago Press","doi":"10.1086/698996","usgsCitation":"Whiteman, J.P., Harlow, H.J., Durner, G.M., Regehr, E.V., Amstrup, S.C., and Ben-David, M., 2019, Heightened immune system function in polar bears using terrestrial habitats: Physiological and Biochemical Zoology, v. 92, no. 1, p. 1-11, https://doi.org/10.1086/698996.","productDescription":"11 p.","startPage":"1","endPage":"11","ipdsId":"IP-094063","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":366391,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"1","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Whiteman, John P.","contributorId":194427,"corporation":false,"usgs":false,"family":"Whiteman","given":"John","email":"","middleInitial":"P.","affiliations":[{"id":17842,"text":"University of Wyoming, Laramie","active":true,"usgs":false}],"preferred":false,"id":768019,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harlow, Henry J.","contributorId":195844,"corporation":false,"usgs":false,"family":"Harlow","given":"Henry","email":"","middleInitial":"J.","affiliations":[{"id":17842,"text":"University of Wyoming, Laramie","active":true,"usgs":false}],"preferred":false,"id":768020,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Durner, George M. 0000-0002-3370-1191 gdurner@usgs.gov","orcid":"https://orcid.org/0000-0002-3370-1191","contributorId":3576,"corporation":false,"usgs":true,"family":"Durner","given":"George","email":"gdurner@usgs.gov","middleInitial":"M.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":768018,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Regehr, Eric V. 0000-0003-4487-3105","orcid":"https://orcid.org/0000-0003-4487-3105","contributorId":66364,"corporation":false,"usgs":false,"family":"Regehr","given":"Eric","email":"","middleInitial":"V.","affiliations":[{"id":12428,"text":"U.

Black brant geese (Branta bernicla nigricans) fledge more goslings, on average, when their broods are experimentally enlarged to be greater than the most common clutch size of four eggs. Thus, we hypothesized that the lesser frequency of brant clutches exceeding four eggs results, at least partially, from a future reduction in survival, breeding probability, or clutch size for females tending larger broods. We used an eight-year mark-recapture dataset (Barker robust design) with five years of clutch and brood manipulations to estimate long-term consequences of reproductive decisions in brant. We did not find evidence of a trade-off between reproductive effort and true survival or future initiation date and clutch size. Rather, future breeding probability was maximized (0.92 ± 0.03 [se]) for manipulated females tending broods of four goslings and lower for females tending smaller (one gosling; 0.63 ± 0.09 [se]) or larger broods (seven goslings; 0.52 ± 0.15 [se]). Our results suggest that demographic trade-offs for female brant tending large broods may reduce the fitness value of clutches larger than four and, therefore, contribute to the paucity of larger clutches. The lack of a trade-off between reproductive effort and survival provides evidence that survival, to which fitness is most sensitive in long-lived animals, is buffered against temporal variation in brant.","language":"English","publisher":"University of Chicago Press","doi":"10.1086/701783","usgsCitation":"Alan Leach, James Sedinger, Riecke, T., Van Dellen, A., Ward, D.H., and Sean Boyd, 2019, Brood size affects future reproduction in a long-lived bird with precocial young: American Naturalist, v. 193, no. 3, p. 458-471, https://doi.org/10.1086/701783.","productDescription":"14 p.","startPage":"458","endPage":"471","ipdsId":"IP-066700","costCenters":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":362384,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"193","issue":"3","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Alan Leach","contributorId":211896,"corporation":false,"usgs":false,"family":"Alan Leach","affiliations":[{"id":36666,"text":"Department of Natural Resources and Environmental Science, University of Nevada-Reno","active":true,"usgs":false}],"preferred":false,"id":755158,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"James Sedinger","contributorId":203592,"corporation":false,"usgs":false,"family":"James Sedinger","affiliations":[{"id":36666,"text":"Department of Natural Resources and Environmental Science, University of Nevada-Reno","active":true,"usgs":false}],"preferred":false,"id":755159,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Riecke, Thomas","contributorId":211897,"corporation":false,"usgs":false,"family":"Riecke","given":"Thomas","email":"","affiliations":[{"id":36666,"text":"Department of Natural Resources and Environmental Science, University of Nevada-Reno","active":true,"usgs":false}],"preferred":false,"id":755160,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Van Dellen, Amanda","contributorId":211898,"corporation":false,"usgs":false,"family":"Van Dellen","given":"Amanda","email":"","affiliations":[{"id":36666,"text":"Department of Natural Resources and Environmental Science, University of Nevada-Reno","active":true,"usgs":false}],"preferred":false,"id":755161,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ward, David H. 0000-0002-5242-2526 dward@usgs.gov","orcid":"https://orcid.org/0000-0002-5242-2526","contributorId":3247,"corporation":false,"usgs":true,"family":"Ward","given":"David","email":"dward@usgs.gov","middleInitial":"H.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":755157,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sean Boyd","contributorId":203594,"corporation":false,"usgs":false,"family":"Sean Boyd","affiliations":[{"id":36668,"text":"Science and Technology Branch, Environment and Climate Change Canada","active":true,"usgs":false}],"preferred":false,"id":755162,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We used vessel-based surveys to examine the seasonal distribution of Dall's porpoise in the waters of Prince William Sound during eight years from 2007 to 2015. Over the course of 168 days and 15,653. km of survey effort, 921 Dall's porpoise were encountered in 210 groups. We estimate an encounter rate of 0.061 porpoise/km traveled or 1 porpoise encountered for every 16.5. km traveled. Dall's porpoise were found throughout the year in Prince William Sound, and used a wide range of habitats, including those not considered typical of the species, such as bays, shallow water, and nearshore waters. Dall's porpoise seasonally shifted their center of distribution from the western passages in fall to the bays of the eastern Sound in winter and spring. Dall's porpoises were widely dispersed throughout the Sound in summer. We identified potential Dall's porpoise habitat (depth, slope, and distance from shore) within Prince William Sound using generalized additive models (GAM). Dall's porpoise were found in deeper water during summer and in shallowest water during spring. We propose that their use of novel habitats is a function of reduced predation risk associated with the decline of their main predator, killer whales (Orcinus orca), following the Exxon Valdez oil spill, and the presence of overwintering and spawning Pacific herring (Clupea pallasii). While the size of the Dall's porpoise population within Prince William Sound remains unknown, our encounter rates were lower than those reported in the 1970s. Their high metabolic rate and ubiquitous presence makes them one of the more important, yet understudied, forage fish predators in the region.","language":"English","doi":"10.1016/j.dsr2.2017.11.002","usgsCitation":"Moran, J., O’Dell, M., Arimitsu, M.L., Straley, J.M., and Dickson, D., 2019, Seasonal distribution of Dall's porpoise in Prince William Sound, Alaska: Deep Sea Research Part II: Topical Studies in Oceanography, v. 147, p. 164-172, https://doi.org/10.1016/j.dsr2.2017.11.002.","productDescription":"9 p.","startPage":"164","endPage":"172","ipdsId":"IP-081589","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":467953,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.dsr2.2017.11.002","text":"Publisher Index Page"},{"id":363644,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Prince William Sound","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -148.5,60.0 ], [ -148.5,61.0 ], [ -146.5,61.0 ], [ -146.5,60.0 ], [ -148.5,60.0 ] ] ] } } ] }","volume":"147","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Moran, J.R.","contributorId":215437,"corporation":false,"usgs":false,"family":"Moran","given":"J.R.","email":"","affiliations":[{"id":12520,"text":"NOAA National Marine Fisheries Service","active":true,"usgs":false}],"preferred":false,"id":762359,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Dell, M.B.","contributorId":215438,"corporation":false,"usgs":false,"family":"O’Dell","given":"M.B.","email":"","affiliations":[{"id":12520,"text":"NOAA National Marine Fisheries Service","active":true,"usgs":false}],"preferred":false,"id":762360,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arimitsu, Mayumi L. 0000-0001-6982-2238 marimitsu@usgs.gov","orcid":"https://orcid.org/0000-0001-6982-2238","contributorId":140501,"corporation":false,"usgs":true,"family":"Arimitsu","given":"Mayumi","email":"marimitsu@usgs.gov","middleInitial":"L.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":762358,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Straley, Jan M","contributorId":215440,"corporation":false,"usgs":false,"family":"Straley","given":"Jan","email":"","middleInitial":"M","affiliations":[{"id":16298,"text":"University of Alaska Southeast","active":true,"usgs":false}],"preferred":false,"id":762362,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dickson, D.M.S.","contributorId":215439,"corporation":false,"usgs":false,"family":"Dickson","given":"D.M.S.","email":"","affiliations":[{"id":39247,"text":"North Pacific Research Board","active":true,"usgs":false}],"preferred":false,"id":762361,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Regional&nbsp;shear wave&nbsp;analyses suggest that the Craig&nbsp;earthquake rupturepropagated in the northward direction faster than the&nbsp;S-wave&nbsp;(supershear).&nbsp;Theoretical studies&nbsp;suggest that a bimaterial interface, such as that along the QCF, which separates oceanic and&nbsp;continental crust&nbsp;with differing elastic properties, can promote supershear rupture propagation. We deployed short-period&nbsp;ocean-bottom seismometers&nbsp;(OBS) as a part of a rapid-response effort less than four months after the Craig earthquake mainshock. During a 21-day period, 1,133&nbsp;aftershocks&nbsp;were recorded by 8 OBS instruments. Aftershock&nbsp;spatial distribution&nbsp;indicates that the base of the seismogenic zone along the QCF approaches ∼25 km depth, consistent with a thermally-controlled fault&nbsp;rheology&nbsp;expected for igneous rocks at oceanic&nbsp;transform faults. The spatial distribution also provides supporting evidence for a previously hypothesized active strand of the QCF system within the&nbsp;Pacific Plate.

Our results suggest that elastic properties along the studied portion of the QCF are different than those of a simple oceanic–continental plate boundary fault. In our study region, velocity structure across the QCF, while bimaterial, does not support faster material on the west side of the fault, which has been proposed as one possible explanation for northward supershear propagation during the Craig earthquake. Instead, we image low-velocity material on the west side of the fault. Explanations could include that part of the rupture was subshear, or that fault damage zone properties or fault smoothness are more important controls on supershear rupture than a bimaterial contrast.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2018.11.021","usgsCitation":"Walton, M.A., Roland, E., Walter, J.I., Gulick, S.P., and Dotray, P., 2019, Seismic velocity structure across the 2013 Craig, Alaska rupture from aftershock tomography: Implications for seismogenic conditions: Earth and Planetary Science Letters, v. 507, p. 94-104, https://doi.org/10.1016/j.epsl.2018.11.021.","productDescription":"11 p.","startPage":"94","endPage":"104","ipdsId":"IP-085883","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":467964,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.epsl.2018.11.021","text":"Publisher Index Page"},{"id":360813,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","city":"Craig","otherGeospatial":"Queen Charlotte Fault","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -140,\n              50\n            ],\n            [\n              -128,\n              50\n            ],\n            [\n              -128,\n              60\n            ],\n            [\n              -140,\n              60\n            ],\n            [\n              -140,\n              50\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"507","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Walton, Maureen A.

Statistical analysis of their size distributions has been hindered by the shortage of observations at sufficiently high spatial resolutions. This situation has now changed with the high-resolution (&lt;5 m) circum-Arctic Permafrost Region Pond and Lake (PeRL) database recently becoming available. We have used this database to make the first consistent, high-resolution estimation of Arctic waterbody size distributions, with surface areas ranging from 0.0001 km</span><sup>2</sup><span>&nbsp;(100 m</span><sup>2</sup><span>) to 1 km</span><sup>2</sup><span>. We found that the size distributions varied greatly across the thirty study regions investigated and that there was no single universal size distribution function (including power-law distribution functions) appropriate across all of the study regions. We did, however, find close relationships between the statistical moments (mean, variance, and skewness) of the waterbody size distributions from different study regions. Specifically, we found that the spatial variance increased linearly with mean waterbody size (</span><i>R</i><sup>2</sup><span>&nbsp;= 0.97,&nbsp;</span><i>p</i><span>&nbsp;&lt; 2.2e-16) and that the skewness decreased approximately hyperbolically. We have demonstrated that these relationships (1) hold across the 30 Arctic study regions covering a variety of (bio)climatic and permafrost zones, (2) hold over time in two of these study regions for which multi-decadal satellite imagery is available, and (3) can be reproduced by simulating rising water levels in a high-resolution digital elevation model. The consistent spatial and temporal relationships between the statistical moments of the waterbody size distributions underscore the dominance of topographic controls in lowland permafrost areas. These results provide motivation for further analyses of the factors involved in waterbody development and spatial distribution and for investigations into the possibility of using statistical moments to predict future hydrologic dynamics in the Arctic.</span></p>","language":"English","publisher":"Frontiers Media","doi":"10.3389/feart.2019.00005","usgsCitation":"Muster, S., Riley, W.J., Roth, K.,

Together, over 1500 km of AEM data, and roughly 30 years of Landsat data were used to explore processes that drive lake dynamics across a variety of permafrost thaw states not possible in studies conducted with satellite imagery or field measurements alone. Clustered time-series data identified lakes with similar temporal dynamics. Clusters possessed similarities in lake permanence (i.e. ephemeral versus perennial), subsurface permafrost distribution, and proximity to rivers and streams. Of the clustered lakes, ~66% are inferred to have at least intermittent connectivity with other surface-water features, ~19% are inferred to have shallow subsurface connectivity to other surface water features that served as a low-pass filter for hydroclimatic fluctuations, and ~15% appear to be isolated by surrounding permafrost (i.e. no connectivity). Integrated analysis of AEM and Landsat data reveals a progression from relatively synchronous lake dynamics among disconnected lakes in the most spatially continuous, thick permafrost to quite high spatiotemporal heterogeneity in lake behavior among variably-connected lakes in regions with notably less continuous permafrost. Variability can be explained by the preferential development of thawed permeable gravel pathways for lateral water redistribution in this area. The general spatial progression in permafrost thaw state and lake area behavior may be extended to the temporal dimension. However, extensive permafrost thaw, beyond what is currently observed, is expected to promote ubiquitous subsurface connectivity, eventually evolving to a state of increased lake synchronicity.</span></p>","language":"English","publisher":"IOP Publishing","doi":"10.1088/1748-9326/aaf06f","usgsCitation":"Rey, D., Walvoord, M., Minsley, B., Rover, J., and Singha, K., 2019, Investigating lake-area dynamics across a permafrost-thaw spectrum using airborne electromagnetic surveys and remote sensing time-series data in Yukon Flats, Alaska: Environmental Research Letters, v. 14, no. 2, p. 1-13, https://doi.org/10.1088/1748-9326/aaf06f.","productDescription":"Article 025001; 13 p.","startPage":"1","endPage":"13","ipdsId":"IP-098493","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"links":[{"id":467970,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1088/1748-9326/aaf06f","text":"Publisher Index Page"},{"id":360756,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Yukon Flats","volume":"14","issue":"2","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-21","publicationStatus":"PW","scienceBaseUri":"5c5022c1e4b0708288f7e7cc","contributors":{"authors":[{"text":"Rey, David M. 0000-0003-2629-365X","orcid":"https://orcid.org/0000-0003-2629-365X","contributorId":211848,"corporation":false,"usgs":true,"family":"Rey","given":"David M.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755036,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walvoord, Michelle Ann 0000-0003-4269-8366","orcid":"https://orcid.org/0000-0003-4269-8366","contributorId":211847,"corporation":false,"usgs":true,"family":"Walvoord","given":"Michelle Ann","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755035,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Minsley, Burke 0000-0003-1689-1306","orcid":"https://orcid.org/0000-0003-1689-1306","contributorId":211849,"corporation":false,"usgs":true,"family":"Minsley","given":"Burke","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true},{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":false,"id":755037,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rover, Jennifer 0000-0002-3437-4030","orcid":"https://orcid.org/0000-0002-3437-4030","contributorId":211850,"corporation":false,"usgs":true,"family":"Rover","given":"Jennifer","email":"","affiliations":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":755038,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Singha, Kamini 0000-0002-0605-3774","orcid":"https://orcid.org/0000-0002-0605-3774","contributorId":191366,"corporation":false,"usgs":false,"family":"Singha","given":"Kamini","email":"","affiliations":[{"id":6606,"text":"Colorado School of Mines","active":true,"usgs":false}],"preferred":false,"id":755039,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Many studies focused on permafrost microbial community composition use DNA-based methods such as metagenomic and 16S rRNA gene sequencing. However, these methods do not distinguish between active, dead, and dormant cells. This is of particular concern in ancient permafrost where constant subzero temperatures preserve DNA from dead organisms and dormancy may be a common survival strategy. To circumvent this we applied: (i) live/dead differential staining coupled with microscopy, (ii) endospore enrichment, and (iii) selective depletion of DNA from dead cells to permafrost microbial communities across a Pleistocene permafrost chronosequence (19 thousand years (K), 27K, and 33K). Cell counts and analysis of 16S rRNA gene amplicons from live, dead, and dormant cells revealed how communities differ between these pools, how they are influenced by soil physicochemical properties, and whether they change over geologic time. We found evidence that cells capable of forming endospores are not necessarily dormant and that members of class Bacilli were more likely to form endospores in response to long-term stressors associated with permafrost environmental conditions than members of Clostridia, which were more likely to persist as vegetative cells in our older samples. We also found that removing exogenous ‘relic’ DNA preserved within permafrost did not significantly alter microbial community composition. These results link the live, dead, and dormant microbial communities to physicochemical characteristics and provides insights into the survival of microbial communities in ancient permafrost.","language":"English","publisher":"American Society for Microbiology","doi":"10.1128/AEM.02646-18","usgsCitation":"Burkert, A., Douglas, T.A., Waldrop, M., and Mackelprang, R., 2019, Changes in the active, dead, and dormant microbial community structure across a Pleistocene permafrost chronosequence: Applied and Environmental Microbiology, v. 85, no. 7, e02646-18: 52 p., https://doi.org/10.1128/AEM.02646-18.","productDescription":"e02646-18: 52 p.","ipdsId":"IP-101909","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":467982,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1128/aem.02646-18","text":"Publisher Index Page"},{"id":365297,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"85","issue":"7","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Burkert, Alexander","contributorId":201933,"corporation":false,"usgs":false,"family":"Burkert","given":"Alexander","email":"","affiliations":[{"id":36305,"text":"CSU Northridge","active":true,"usgs":false}],"preferred":false,"id":765487,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Douglas, Thomas A. 0000-0003-1314-1905","orcid":"https://orcid.org/0000-0003-1314-1905","contributorId":64553,"corporation":false,"usgs":false,"family":"Douglas","given":"Thomas","email":"","middleInitial":"A.","affiliations":[{"id":33087,"text":"Cold Regions Research and Engineering Laboratory","active":true,"usgs":false}],"preferred":true,"id":765488,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Waldrop, Mark 0000-0003-1829-7140","orcid":"https://orcid.org/0000-0003-1829-7140","contributorId":216780,"corporation":false,"usgs":true,"family":"Waldrop","given":"Mark","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":765486,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mackelprang, Rachel","contributorId":200882,"corporation":false,"usgs":false,"family":"Mackelprang","given":"Rachel","email":"","affiliations":[{"id":7080,"text":"California State University, Northridge","active":true,"usgs":false}],"preferred":false,"id":765489,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Permafrost thaw affects soil carbon turnover through changes in soil hydrology, however, the biotic mechanisms regulating plant community response remain elusive. Here, we measured the response of fungal community composition and soil nutrient content in an intact permafrost plateau forest soil and an adjacent thermokarst bog using barcoded amplicon targeting ITS2 and 28S rRNA genes. Next, we used the soils from the permafrost plateau and the thermokarst bog as soil inoculum in a greenhouse experiment to measure whether shifts in fungal community and soil water level regulate plant productivity. Overall, we found that fungal community composition differed significantly between the thawed and intact permafrost sites, but soil nutrient content did not. Relative abundance of mycorrhizal fungal taxa decreased while relative abundance of putative fungal pathogens increased with permafrost thaw. In the greenhouse, we found that ecto- and arbuscular associated host plants had higher productivity in permafrost-intact soils relative to thawed soils. However, productivity of non-mycorrhizal tussock grass was more affected by soil water levels than soil communities. Our results suggest that fungal communities are crucial in mediating plant response to permafrost thaws inducing hydrology changes.","language":"English","publisher":"Wiley","doi":"10.1111/1365-2745.13139","usgsCitation":"Schütte, U., Henning, J.A., Ye, Y., Bowling, A., Ford, J.D., Genet, H., Waldrop, M., Turetsky, M.R., White, J.R., and Bever, J.D., 2019, Effect of permafrost thaw on plant and soil fungal community in the boreal forest: Does fungal community change mediate plant productivity response?: Journal of Ecology, v. 107, no. 4, p. 1737-1752, https://doi.org/10.1111/1365-2745.13139.","productDescription":"16 p.","startPage":"1737","endPage":"1752","ipdsId":"IP-103772","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":467984,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/1365-2745.13139","text":"Publisher Index Page"},{"id":365296,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"107","issue":"4","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2019-03-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Schütte, Ursel M.E","contributorId":216770,"corporation":false,"usgs":false,"family":"Schütte","given":"Ursel M.E","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":765468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Henning, Jeremiah A.","contributorId":216771,"corporation":false,"usgs":false,"family":"Henning","given":"Jeremiah","email":"","middleInitial":"A.","affiliations":[{"id":6626,"text":"University of Minnesota","active":true,"usgs":false}],"preferred":false,"id":765469,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ye, Yuzhen","contributorId":216772,"corporation":false,"usgs":false,"family":"Ye","given":"Yuzhen","email":"","affiliations":[{"id":39512,"text":"Indiana Univerisity","active":true,"usgs":false}],"preferred":false,"id":765470,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bowling, A.","contributorId":119396,"corporation":false,"usgs":true,"family":"Bowling","given":"A.","email":"","affiliations":[],"preferred":false,"id":765473,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ford, James D.","contributorId":200964,"corporation":false,"usgs":false,"family":"Ford","given":"James","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":765471,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Genet, Helene","contributorId":198686,"corporation":false,"usgs":false,"family":"Genet","given":"Helene","email":"","affiliations":[],"preferred":false,"id":765472,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Waldrop, Mark 0000-0003-1829-7140","orcid":"https://orcid.org/0000-0003-1829-7140","contributorId":216769,"corporation":false,"usgs":true,"family":"Waldrop","given":"Mark","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":765467,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Turetsky, Merritt R.","contributorId":169398,"corporation":false,"usgs":false,"family":"Turetsky","given":"Merritt","email":"","middleInitial":"R.","affiliations":[{"id":12660,"text":"University of Guelph","active":true,"usgs":false}],"preferred":false,"id":765474,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"White, Jeffrey R.","contributorId":169414,"corporation":false,"usgs":false,"family":"White","given":"Jeffrey","email":"","middleInitial":"R.","affiliations":[{"id":12645,"text":"Indiana University - Northwest","active":true,"usgs":false}],"preferred":false,"id":765475,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Bever, James D","contributorId":216774,"corporation":false,"usgs":false,"family":"Bever","given":"James","email":"","middleInitial":"D","affiliations":[{"id":39513,"text":"Kansas University","active":true,"usgs":false}],"preferred":false,"id":765476,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Belowground, the potential responses of soil systems are less well known. We used geochemical steady state models, soil density fractionation, and soil radiocarbon data to constrain changes in soil carbon based on measurements from detrital (free light), aggregate-bound (occluded) and complexed or chemically bound (mineral associated) carbon pools and for bulk soil. We explored a space-for-time sequence of soils along a cold-to-warm climatic gradient from Alaskan Black Spruce forest soil with permafrost (Gelisols; 50 cm Mean Annual Temperature −1.5 ºC), Alaskan White Spruce forest soil lacking permafrost (Inceptisols; 50 cm MAT +3 ºC ), and Iowa Grassland soil lacking permafrost (Mollisols; 50 cm MAT +9 ºC) developed on similar geologic substrates (wind-blown loess deposits). These temperature ranges were also representative of temperatures at 50 cm soil depth from model output by the Community Land Model for the years 2014, 2100, and 2300 for Interior Alaska. Fitting an exponential equation to depth trends in soil C down to 2 m depths, we found that depth distributions of organic C were related mainly to depths of rooting and changes in bulk density. Using output from the geochemical steady state model, the direction and magnitude of the C loss or gain upon ecosystem shift was dictated by the C stocks of initial and final ecosystems. Radiocarbon measurements specific to each soil fraction (free light, occluded, and mineral associated) allowed us to constrain the timing of the potential loss or gain of C in each fraction driven by climatic shifts. Thawing from the Gelisol to Inceptisol in loess parent materials from present day to year 2100 resulted in small net gains to soil C, reflecting the net balance between loss of detrital and gain into occluded and mineral associated C. Greater warming and shifts from Inceptisol to Mollisol analogous to predicted warming from circa 2100 to 2300 resulted in net C losses from both occluded and mineral associated C, although small gains to the free light C fraction occurred throughout the depth profile. Gains to occluded and mineral associated C post- thaw likely reflect aggregate formation and physical protection of C as well as formation of organo-mineral compounds that accompany microbial processing. Greater warming and shifts from Inceptisol to Mollisol, which are analogous to predicted warming circa 2100 to 2300, resulted in net C losses from both occluded and mineral associated C resulting from enhanced decomposition, small gains to the free light C fraction occurred throughout the transition to Mollisol reflecting deeper rooting of the tallgrass prairie system.","language":"English","publisher":"European Geosciences Union (EGU)","doi":"10.5194/soil-2018-41","usgsCitation":"Harden, J.W., O’Donnell, J., Heckman, K., Sulman, B., Koven, C., Ping, C., and Michaelson, G., 2019, Beneath the arctic greening: Will soils lose or gain carbon or perhaps a little of both?: SOIL, 22 p., https://doi.org/10.5194/soil-2018-41.","productDescription":"22 p.","ipdsId":"IP-103776","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":467986,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.5194/soil-2018-41","text":"External Repository"},{"id":363102,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"edition":"Online First","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Harden, Jennifer W. 0000-0002-6570-8259 jharden@usgs.gov","orcid":"https://orcid.org/0000-0002-6570-8259","contributorId":1971,"corporation":false,"usgs":true,"family":"Harden","given":"Jennifer","email":"jharden@usgs.gov","middleInitial":"W.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":761184,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Donnell, J.A.","contributorId":214930,"corporation":false,"usgs":false,"family":"O’Donnell","given":"J.A.","email":"","affiliations":[{"id":39140,"text":"Arctic Network, National Park Service, Anchorage, Alaska","active":true,"usgs":false}],"preferred":false,"id":761185,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Heckman, K.A.","contributorId":197919,"corporation":false,"usgs":false,"family":"Heckman","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":761186,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sulman, B.N.","contributorId":214931,"corporation":false,"usgs":false,"family":"Sulman","given":"B.N.","email":"","affiliations":[{"id":37400,"text":"Environmental Sciences Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee","active":true,"usgs":false}],"preferred":false,"id":761187,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Koven, C.D.","contributorId":199628,"corporation":false,"usgs":false,"family":"Koven","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":761188,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ping, C.L.","contributorId":199629,"corporation":false,"usgs":false,"family":"Ping","given":"C.L.","affiliations":[],"preferred":false,"id":761189,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Michaelson, G.J.","contributorId":199630,"corporation":false,"usgs":false,"family":"Michaelson","given":"G.J.","email":"","affiliations":[],"preferred":false,"id":761190,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Prediction of these changes is challenged by incomplete knowledge of timing, flowpath depth, and amount of groundwater discharge to streams in response to thaw. One important phenomenon that may affect flow and transport through boreal hillslopes is development of lateral perennial thaw zones (PTZs), the existence of which is here supported by geophysical observations and cryohydrogeologic modeling. Model results link thaw to enhanced and seasonally-extended baseflow, which have implications for mobilization of soluble constituents. Results demonstrate the sensitivity of PTZ development to organic layer thickness and near-surface factors that mediate heat exchange at the atmosphere/ground-surface interface. Study findings suggest that PTZs serve as a detectable precursor to accelerated permafrost degradation. This study provides important contextual insight on a fundamental thermo-hydrologic process that can enhance terrestrial-to-aquatic transfer of permafrost carbon, nitrogen, and mercury previously sequestered in thawing watersheds.</span></p>","language":"English","publisher":"IOP Publishing","doi":"10.1088/1748-9326/aaf0cc","usgsCitation":"Walvoord, M.A., Voss, C., Ebel, B., and Minsley, B.J., 2019, Development of perennial thaw zones in boreal hillslopes enhances potential mobilization of permafrost carbon: Environmental Research Letters, v. 14, no. 1, p. 1-11, https://doi.org/10.1088/1748-9326/aaf0cc.","productDescription":"Article 015003; 11 p.","startPage":"1","endPage":"11","ipdsId":"IP-098066","costCenters":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"links":[{"id":467989,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1088/1748-9326/aaf0cc","text":"Publisher Index Page"},{"id":437601,"rank":0,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P9HWCOBP","text":"USGS data release","linkHelpText":"Model Archive for coupled energy and fluid flow simulations generalized to boreal hillslopes"},{"id":360760,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"14","issue":"1","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-17","publicationStatus":"PW","scienceBaseUri":"5c5022c3e4b0708288f7e800","contributors":{"authors":[{"text":"Walvoord, Michelle A. 0000-0003-4269-8366","orcid":"https://orcid.org/0000-0003-4269-8366","contributorId":211843,"corporation":false,"usgs":true,"family":"Walvoord","given":"Michelle","email":"","middleInitial":"A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voss, Clifford I. 0000-0001-5923-2752","orcid":"https://orcid.org/0000-0001-5923-2752","contributorId":211844,"corporation":false,"usgs":true,"family":"Voss","given":"Clifford I.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755032,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ebel, Brian A. 0000-0002-5413-3963","orcid":"https://orcid.org/0000-0002-5413-3963","contributorId":211845,"corporation":false,"usgs":true,"family":"Ebel","given":"Brian A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755033,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Minsley, Burke J. 0000-0003-1689-1306 bminsley@usgs.gov","orcid":"https://orcid.org/0000-0003-1689-1306","contributorId":697,"corporation":false,"usgs":true,"family":"Minsley","given":"Burke","email":"bminsley@usgs.gov","middleInitial":"J.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":755034,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Despite the species’ large size and the small mass of the transmitters, we documented potential negative effects of externally mounted transmitters on the survival of Bristle-thighed Curlews. We also documented apparent effects of age and sex on the survival of curlews, underscoring the difficulty of disentangling the effects of research techniques on study subjects.

Northern latitudes are expected to get warmer and wetter, and while there is consensus that warming will increase thaw and methane emissions, effects of increased precipitation are uncertain. At a thawing wetland complex in Interior Alaska, we found that interactions between rain and deep soil temperatures controlled methane emissions. In rainy years, recharge from the watershed rapidly altered wetland soil temperatures, warming the top ~80 cm of soil in spring and summer and cooling it in autumn. When soils were warmed by spring rainfall, methane emissions increased by ~30%. The warm, deep soils early in the growing season likely supported both microbial and plant processes that enhanced emissions. Our study identifies an important and unconsidered role of rain in governing the radiative forcing of thawing permafrost landscapes.","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2018GL081274","usgsCitation":"Neumann, R.B., Moorberg, C., Lundquist, J., Turner, J., Waldrop, M.P., McFarland, J.W., Euskirchen, E., Edgar, C., and Turetsky, M.R., 2019, Warming effects of spring rainfall increase methane emissions from thawing permafrost: Geophysical Research Letters, v. 46, no. 3, p. 1393-1401, https://doi.org/10.1029/2018GL081274.","productDescription":"9 p.","startPage":"1393","endPage":"1401","ipdsId":"IP-100436","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":468005,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2018gl081274","text":"Publisher Index Page"},{"id":365293,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"46","issue":"3","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2019-02-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Neumann, Rebecca B.","contributorId":216775,"corporation":false,"usgs":false,"family":"Neumann","given":"Rebecca","email":"","middleInitial":"B.","affiliations":[{"id":6934,"text":"University of Washington","active":true,"usgs":false}],"preferred":false,"id":765478,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moorberg, C.J.","contributorId":216776,"corporation":false,"usgs":false,"family":"Moorberg","given":"C.J.","affiliations":[{"id":12661,"text":"Kansas State University","active":true,"usgs":false}],"preferred":false,"id":765479,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lundquist, J.D.","contributorId":178771,"corporation":false,"usgs":false,"family":"Lundquist","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":765480,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Turner, J.C.","contributorId":216777,"corporation":false,"usgs":false,"family":"Turner","given":"J.C.","email":"","affiliations":[{"id":6934,"text":"University of Washington","active":true,"usgs":false}],"preferred":false,"id":765481,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Waldrop, Mark P. 0000-0003-1829-7140 mwaldrop@usgs.gov","orcid":"https://orcid.org/0000-0003-1829-7140","contributorId":1599,"corporation":false,"usgs":true,"family":"Waldrop","given":"Mark","email":"mwaldrop@usgs.gov","middleInitial":"P.","affiliations":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":765477,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"McFarland, Jack W. 0000-0001-9672-8597 jmcfarland@usgs.gov","orcid":"https://orcid.org/0000-0001-9672-8597","contributorId":5238,"corporation":false,"usgs":true,"family":"McFarland","given":"Jack","email":"jmcfarland@usgs.gov","middleInitial":"W.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":765482,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Euskirchen, E.S.","contributorId":216778,"corporation":false,"usgs":false,"family":"Euskirchen","given":"E.S.","email":"","affiliations":[{"id":36971,"text":"University of Alaska","active":true,"usgs":false}],"preferred":false,"id":765483,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Edgar, C.W.","contributorId":173731,"corporation":false,"usgs":false,"family":"Edgar","given":"C.W.","email":"","affiliations":[{"id":7211,"text":"University of Alaska, Fairbanks","active":true,"usgs":false}],"preferred":false,"id":765484,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Turetsky, M.

Evidence suggests that introduced species with generalist diets have the potential for greatest impacts through competition and predation even though populations are often comprised of specialist individuals. The northern pike (Esox lucius), a predatory fish, has been widely introduced outside its native range for recreational fishing purposes, especially in western North America, and it has been implicated in declines and extirpations of native fishes. We synthesized over 2,900 individual northern pike diet records across 31 waterbodies from the native and introduced ranges in Alaska to quantify the extent of diet specialization and generalization relative to freshwater prey communities. To control for effects of ontogenetic diet shifts, we separately analyzed major size classes of northern pike and inferred and visualized trophic plasticity from Prey-Specific Abundance indices and ordination. Diet generalization was common in northern pike among waterbodies and usually consisted of individuals consuming macroinvertebrates. However, when available, individual northern pike diets showed specialization on fishes, amphibians, small mammals, and dragonflies. The reliance on macroinvertebrate prey by northern pike from small, isolated lakes in the native and invasive ranges suggests that dietary plasticity facilitates persistence of these predators in the absence of preferred fish prey. Broadly, this synthesis supports the hypothesis that trophic plasticity and diet generalization widely occur among invasive and native populations of northern pike which is likely to enhance the probability of introduction success, exacerbate their environmental impacts, and complicate management of this potentially invasive freshwater predator.","language":"English","publisher":"Springer","doi":"10.1007/s10530-018-1909-7","usgsCitation":"Cathcart, C.N., Dunker, K.J., Quinn, T.P., Sepulveda, A.J., von Hippel, F.A., Wizik, A., Young, D.B., and Westley, P.A., 2019, Trophic plasticity and the invasion of a renowned piscivore: A diet synthesis of northern pike (Esox lucius) from the native and introduced ranges in Alaska, U.S.A.: Biological Invasions, v. 21, no. 4, p. 1379-1392, https://doi.org/10.1007/s10530-018-1909-7.","productDescription":"14 p.","startPage":"1379","endPage":"1392","ipdsId":"IP-103289","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":361977,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -159.521484375,\n              57.961503094284794\n            ],\n            [\n              -146.0302734375,\n              57.961503094284794\n            ],\n            [\n              -146.0302734375,\n              62.36999628130772\n            ],\n            [\n              -159.521484375,\n              62.36999628130772\n            ],\n            [\n              -159.521484375,\n              57.961503094284794\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"21","issue":"4","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Cathcart, C.

Incorporating measures of reproductive success or survival into these models helps address the role of vital rates (a surrogate of fitness) in affecting a species’ distribution. We used 24-year datasets of Arctic peregrine falcon (<i>Falco peregrinus tundrius</i>) nest-site locations and productivity from the Colville River Special Area, Alaska, USA to model suitability of breeding habitat and the relative quality of used and potential nest sites. We used zero-inflated negative binomial regression models and covariates describing nest-site productivity, area of surrounding prey habitat, geology, topography, and land-cover type to model and predict intensity of Arctic peregrine falcon nest-site use along the Colville River, and developed a predictive map of intensity of nest-site use. Regions of higher predicted intensity of use were characterized by steeper slopes, greater area of prey habitat, and higher average productivity, which are likely attributed to minimizing predation risk, gaining advantages for hunting, having sufficient prey resources, site quality, and overall fitness. Including productivity in intensity of nest-site use models improved the models, supporting our supposition that adding a fitness parameter enhanced the predictive capability of the species distribution model. Areas predicted to have higher intensity of use by our model can be used to focus efforts of continued protection of areas with frequently occupied and productive nest sites, and conversely, identify areas where protection of nest sites is likely to have few conservation benefits.</p>","language":"English","publisher":"BioOne","doi":"10.2981/wlb.00475","usgsCitation":"Andersen, D.E., Bruggeman, J.E., Swem, T., Kennedy, P.L., and Debora Nigro, 2019, Incorporating productivity as a measure of fitness into models of breeding area quality of Arctic peregrine falcons: Wildlife Biology, 00475, 12 p., https://doi.org/10.2981/wlb.00475.","productDescription":"00475, 12 p.","ipdsId":"IP-084116","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":468040,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2981/wlb.00475","text":"Publisher Index Page"},{"id":365941,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Colville River Special Area","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -158.0,67.0 ], [ -158.0,71.5 ], [ -141.57,71.5 ], [ -141.57,67.0 ], [ -158.0,67.0 ] ] ] } } ] }","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2018-12-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Andersen, David E. 0000-0001-9535-3404 dea@usgs.gov","orcid":"https://orcid.org/0000-0001-9535-3404","contributorId":199408,"corporation":false,"usgs":true,"family":"Andersen","given":"David","email":"dea@usgs.gov","middleInitial":"E.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":767010,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bruggeman, Jason E.","contributorId":217529,"corporation":false,"usgs":false,"family":"Bruggeman","given":"Jason","email":"","middleInitial":"E.","affiliations":[{"id":6626,"text":"University of Minnesota","active":true,"usgs":false}],"preferred":false,"id":767011,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swem, Ted","contributorId":217530,"corporation":false,"usgs":false,"family":"Swem","given":"Ted","email":"","affiliations":[{"id":6654,"text":"USFWS","active":true,"usgs":false}],"preferred":false,"id":767012,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kennedy, Patricia L.","contributorId":217531,"corporation":false,"usgs":false,"family":"Kennedy","given":"Patricia","email":"","middleInitial":"L.","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":767013,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Debora Nigro","contributorId":217532,"corporation":false,"usgs":false,"family":"Debora Nigro","affiliations":[{"id":7217,"text":"Bureau of Land Management","active":true,"usgs":false}],"preferred":false,"id":767014,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
