Increases in the frequency, duration, and/or severity of drought and heat stress associated with climate change could fundamentally alter the composition, structure, and biogeography of forests in many regions. Of particular concern are potential increases in tree mortality associated with climate-induced physiological stress and interactions with other climate-mediated processes such as insect outbreaks and wildfire. Despite this risk, existing projections of tree mortality are based on models that lack functionally realistic mortality mechanisms, and there has been no attempt to track observations of climate-driven tree mortality globally. Here we present the first global assessment of recent tree mortality attributed to drought and heat stress. Although episodic mortality occurs in the absence of climate change, studies compiled here suggest that at least some of the world's forested ecosystems already may be responding to climate change and raise concern that forests may become increasingly vulnerable to higher background tree mortality rates and die-off in response to future warming and drought, even in environments that are not normally considered water-limited. This further suggests risks to ecosystem services, including the loss of sequestered forest carbon and associated atmospheric feedbacks. Our review also identifies key information gaps and scientific uncertainties that currently hinder our ability to predict tree mortality in response to climate change and emphasizes the need for a globally coordinated observation system. Overall, our review reveals the potential for amplified tree mortality due to drought and heat in forests worldwide.","language":"English","publisher":"Elsevier","doi":"10.1016/j.foreco.2009.09.001","usgsCitation":"Allen, C.D., Macalady, A., Chenchouni, H., Bachelet, D., McDowell, N., Vennetier, M., Kitzberger, T., Rigling, A., Breshears, D., Hogg, E.H., Gonzalez, P., Fensham, R., Zhang, Z., Castro, J., Demidova, N., Lim, J., Allard, G., Running, S.W., Semerci, A., and Cobb, N., 2010, A global overview of drought and heat-induced tree mortality reveals emerging climate change risks for forests: Forest Ecology and Management, v. 259, no. 4, p. 660-684, https://doi.org/10.1016/j.foreco.2009.09.001.","productDescription":"25 p.","startPage":"660","endPage":"684","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":487733,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/79d2f7n0","text":"External Repository"},{"id":242105,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"259","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e40ae4b0c8380cd4638c","contributors":{"authors":[{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":true,"id":442918,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Macalady, A.K.","contributorId":42046,"corporation":false,"usgs":true,"family":"Macalady","given":"A.K.","email":"","affiliations":[],"preferred":false,"id":442919,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chenchouni, H.","contributorId":55223,"corporation":false,"usgs":true,"family":"Chenchouni","given":"H.","email":"","affiliations":[],"preferred":false,"id":442923,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bachelet, D.","contributorId":25776,"corporation":false,"usgs":true,"family":"Bachelet","given":"D.","email":"","affiliations":[],"preferred":false,"id":442915,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McDowell, N.","contributorId":86573,"corporation":false,"usgs":true,"family":"McDowell","given":"N.","email":"","affiliations":[],"preferred":false,"id":442928,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vennetier, Michel","contributorId":86184,"corporation":false,"usgs":true,"family":"Vennetier","given":"Michel","email":"","affiliations":[],"preferred":false,"id":442927,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kitzberger, T.","contributorId":97338,"corporation":false,"usgs":true,"family":"Kitzberger","given":"T.","affiliations":[],"preferred":false,"id":442929,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Rigling, A.","contributorId":71014,"corporation":false,"usgs":true,"family":"Rigling","given":"A.","affiliations":[],"preferred":false,"id":442926,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Breshears, D.D.","contributorId":17952,"corporation":false,"usgs":false,"family":"Breshears","given":"D.D.","email":"","affiliations":[{"id":12625,"text":"School of Natural Resources and the Environment, University of Arizona, Tucson, AZ, 85721, USA","active":true,"usgs":false}],"preferred":false,"id":442914,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Hogg, E.

High islands are subjected to constant erosion over geologic time, which establishes an important source of terrigeneous sediment for nearby marine communities. Many of these sediments are deposited in mangrove forests and offer mangroves a potentially important means for adjusting surface elevation with rising sea level. In this study, we investigated sedimentation and elevation dynamics of mangrove forests in three hydrogeomorphic settings on the islands of Kosrae and Pohnpei, Federated States of Micronesia (FSM). Surface accretion rates ranged from 2.9 to 20.8&nbsp;mm&nbsp;y</span><sup>−1</sup><span>, and are high for naturally occurring mangroves. Although mangrove forests in Micronesian high islands appear to have a strong capacity to offset elevation losses by way of sedimentation, elevation change over 6½ years ranged from −3.2 to 4.1&nbsp;mm&nbsp;y</span><sup>−1</sup><span>, depending on the location. Mangrove surface elevation change also varied by hydrogeomorphic setting and river, and suggested differential, and not uniformly bleak, susceptibilities among Pacific high island mangroves to sea-level rise. Fringe, riverine, and interior settings registered elevation changes of −1.30, 0.46, and 1.56&nbsp;mm&nbsp;y</span><sup>−1</sup><span>, respectively, with the greatest elevation deficit (−3.2&nbsp;mm&nbsp;y</span><sup>−1</sup><span>) from a fringe zone on Pohnpei and the highest rate of elevation gain (4.1&nbsp;mm&nbsp;y</span><sup>−1</sup><span>) from an interior zone on Kosrae. Relative to sea-level rise estimates for FSM (0.8–1.8&nbsp;mm&nbsp;y</span><sup>−1</sup><span>) and assuming a consistent linear trend in these estimates, soil elevations in mangroves on Kosrae and Pohnpei are experiencing between an annual deficit of 4.95&nbsp;mm and an annual surplus of 3.28&nbsp;mm. Although natural disturbances are important in mediating elevation gain in some situations, constant allochthonous sediment deposition probably matters most on these Pacific high islands, and is especially helpful in certain hydrogeomorphic zones. Fringe mangrove forests are most susceptible to sea-level rise, such that protection of these outer zones from anthropogenic disturbances (for example, harvesting) may slow the rate at which these zones convert to open water.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10021-009-9307-8","issn":"14329840","usgsCitation":"Krauss, K., Cahoon, D.R., Allen, J.A., Ewel, K.C., Lynch, J., and Cormier, N., 2010, Surface elevation change and susceptibility of different mangrove zones to sea-level rise on Pacific high islands of Micronesia: Ecosystems, v. 13, no. 1, p. 129-143, https://doi.org/10.1007/s10021-009-9307-8.","productDescription":"15 p.","startPage":"129","endPage":"143","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"links":[{"id":241909,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214210,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10021-009-9307-8"}],"volume":"13","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-01-05","publicationStatus":"PW","scienceBaseUri":"505b9fa6e4b08c986b31e74e","contributors":{"authors":[{"text":"Krauss, K.

This fresh water was likely emplaced during Pleistocene sea-level low stands when the shelf was exposed to meteoric recharge and by elevated recharge in areas overrun by the Laurentide ice sheet at high latitudes. To test this hypothesis, we present results from a high-resolution paleohydrologic model of groundwater flow, heat and solute transport, ice sheet loading, and sea level fluctuations for the continental shelf from New Jersey to Maine over the last 2 million years. Our analysis suggests that the presence of fresh to brackish water within shallow Miocene sands more than 100 km offshore of New Jersey was facilitated by discharge of submarine springs along Baltimore and Hudson Canyons where these shallow aquifers crop out. Recharge rates four times modern levels were computed for portions of New England's continental shelf that were overrun by the Laurentide ice sheet during the last glacial maximum. We estimate the volume of emplaced Pleistocene continental shelf fresh water (less than 1 ppt) to be 1300 km<sup>3</sup> in New England. We also present estimates of continental shelf fresh water resources for the U.S. Atlantic eastern seaboard (10<sup>4</sup> km<sup>3</sup>) and passive margins globally (3 x 10<sup>5</sup> km<sup>3</sup>).

Each year, thousands of Black Brent Geese <i>Branta bernicla nigricans</i> migrate to the Teshekpuk Lake Special Area (TLSA), Alaska, to undergo a flightless wing‐moult. Over the last three decades, moulting Brent Geese have changed their distribution within the TLSA, redistributing from inland, freshwater wetlands towards coastal, brackish wetlands. To understand better the mechanism by which Brent Geese select a moult site, as well as reasons behind the long‐term shift of moulting distributions, we examined movements and habitat use of birds marked with GPS‐transmitters during the pre‐moult period. Brent Geese did not generally migrate directly to their moulting site during the pre‐moult period, defined as the time from arrival at the moulting grounds to the onset of flightlessness. Rather, individuals used an average of 3.7 ± 0.6 (se) wetland complexes and travelled a minimum of 95.14 ± 15.84 km during the pre‐moult period. Moreover, 69% of Brent Geese visited their final moult site only to leave and visit other sites before returning for the flightless moult. Brent Geese spent significant time in both inland freshwater and coastal estuarine habitats during the pre‐moult, irrespective of the habitat in which they ultimately moulted. Whereas previous research suggested that Brent Geese choose moult sites based largely upon the experience of previous years, our observations suggest a mechanism of moult site selection whereby Brent Geese ‘prospect’ for moult sites, visiting multiple potential moult sites across varied habitat types, presumably gathering information from each site and correspondingly using this information to choose an appropriate moult site. By allowing individuals to adjust their distributions in response to habitat quality cues that may change annually, such as forage type and availability, prospecting may have influenced the long‐term shift in moulting distributions of Brent Geese in the TLSA<span class=\"smallCaps\">.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1474-919X.2010.01023.x","usgsCitation":"Lewis, T., Flint, P.L., Schmutz, J.A., and Derksen, D.V., 2010, Pre‐moult patterns of habitat use and moult site selection by Brent Geese Branta bernicla nigricans: Individuals prospect for moult sites : Ibis, v. 152, no. 3, p. 556-568, https://doi.org/10.1111/j.1474-919X.2010.01023.x.","productDescription":"13 p.","startPage":"556","endPage":"568","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":354235,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Teshekpuk Lake Special Area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -159.63134765625,\n              68.67254350285471\n            ],\n            [\n              -150.29296875,\n              68.67254350285471\n            ],\n            [\n              -150.29296875,\n              71.62906907439766\n            ],\n            [\n              -159.63134765625,\n              71.62906907439766\n            ],\n            [\n              -159.63134765625,\n              68.67254350285471\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"152","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-06-15","publicationStatus":"PW","scienceBaseUri":"5afef89de4b0da30c1bfc9c2","contributors":{"authors":[{"text":"Lewis, Tyler 0000-0002-4998-3031 tlewis@usgs.gov","orcid":"https://orcid.org/0000-0002-4998-3031","contributorId":169307,"corporation":false,"usgs":true,"family":"Lewis","given":"Tyler","email":"tlewis@usgs.gov","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":735567,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","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":735568,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","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":735569,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Derksen, Dirk V. dderksen@usgs.gov","contributorId":2269,"corporation":false,"usgs":true,"family":"Derksen","given":"Dirk","email":"dderksen@usgs.gov","middleInitial":"V.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":735570,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Methods and Results: Molecular-based techniques [AFLP and rDNA (ITS1, ITS2 and 5??8S) gene sequencing] were used to characterize morphologically identified Metarhizium spp. isolates from a wide range of sources. Conidial suspensions of isolates were exposed to wet heat (45 ?? 0??2??C) and plated on potato dextrose agar plus yeast extract (PDAY) medium. After 8-h exposure, the isolates divided clearly into two groups: (i) all isolates of Metarhizium anisopliae var. anisopliae (Ma-an) and Metarhizium from the flavoviride complex (Mf) had virtually zero conidial relative germination (RG), (ii) Metarhizium anisopliae var. acridum (Ma-ac) isolates demonstrated high heat tolerance (c. 70-100% RG). Conidial suspensions also were plated on PDAY and incubated at 5??C for 15 days, during which time RGs for Ma-an and Ma-ac isolates were virtually zero, whereas the two Mf were highly cold active (100% RG). Conclusions: Heat and cold exposures can be used as rapid tools to tentatively identify some important Metarhizium species and varieties. Significance and Impact of the Study: Identification of Metarhizium spp. currently relies primarily on DNA-based methods; we suggest a simple temperature-based screen to quickly obtain tentative identification of isolates as to species or species complexes. ?? 2009 The Society for Applied Microbiology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2672.2009.04422.x","issn":"13645072","usgsCitation":"Fernandes, E., Keyser, C., Chong, J., Rangel, D., Miller, M., and Roberts, D., 2010, Characterization of Metarhizium species and varieties based on molecular analysis, heat tolerance and cold activity: Journal of Applied Microbiology, v. 108, no. 1, p. 115-128, https://doi.org/10.1111/j.1365-2672.2009.04422.x.","startPage":"115","endPage":"128","numberOfPages":"14","costCenters":[],"links":[{"id":214378,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2672.2009.04422.x"},{"id":242101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"108","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f4b9e4b0c8380cd4be95","contributors":{"authors":[{"text":"Fernandes, E.K.K.","contributorId":87384,"corporation":false,"usgs":true,"family":"Fernandes","given":"E.K.K.","email":"","affiliations":[],"preferred":false,"id":442602,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keyser, C.A.","contributorId":106329,"corporation":false,"usgs":true,"family":"Keyser","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":442603,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chong, J.P.","contributorId":58481,"corporation":false,"usgs":true,"family":"Chong","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":442601,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rangel, D.E.N.","contributorId":32362,"corporation":false,"usgs":true,"family":"Rangel","given":"D.E.N.","email":"","affiliations":[],"preferred":false,"id":442599,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, M.P.","contributorId":47142,"corporation":false,"usgs":true,"family":"Miller","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":442600,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Roberts, D.W.","contributorId":11828,"corporation":false,"usgs":true,"family":"Roberts","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":442598,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

On Earth, debris flows are often triggered by shallow subsurface throughflow of liquid water in slope-mantling colluvium. This flow causes increased levels of pore pressure and thus decreased shear strength, which can lead to slide failure of slope materials and subsequent debris flow. The threshold for pore pressure-induced failure creates a distinct relationship between the contributing area supplying the subsurface flow and the slope gradient. To provide initial tests of a similar debris flow initiation hypothesis for martian gullies, measurements of the contributing areas and slope gradients were made at the channel heads of martian gullies seen in three HiRISE stereo pairs. These gullies exhibit morphologies suggestive of debris flows such as leveed channels and lobate debris fans, and have well-defined channel heads and limited evidence for multiple flows. Our results show an area-slope relationship for these martian gullies that is consistent with that observed for terrestrial gullies formed by debris flow, supporting the hypothesis that these gullies formed as the result of saturation of near-surface regolith by a liquid. This model favors a source of liquid that is broadly distributed within the source area and shallow; we suggest that such liquid could be generated by melting of broadly distributed icy materials such as snow or permafrost. This interpretation is strengthened by observations of polygonal and mantled terrain in the study areas, which are both suggestive of near-surface ice.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.icarus.2009.04.014","issn":"00191035","usgsCitation":"Lanza, N.L., Meyer, G.A., Okubo, C., Newsom, H.E., and Wiens, R., 2010, Evidence for debris flow gully formation initiated by shallow subsurface water on Mars: Icarus, v. 205, no. 1, p. 103-112, https://doi.org/10.1016/j.icarus.2009.04.014.","productDescription":"10 p.","startPage":"103","endPage":"112","numberOfPages":"10","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":242005,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Mars","volume":"205","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d39e4b0c8380cd52eb2","contributors":{"authors":[{"text":"Lanza, Nina L.","contributorId":140299,"corporation":false,"usgs":false,"family":"Lanza","given":"Nina","email":"","middleInitial":"L.","affiliations":[{"id":13447,"text":"Los Alamos National Laboratory","active":true,"usgs":false}],"preferred":false,"id":442884,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meyer, Grant A.","contributorId":26340,"corporation":false,"usgs":false,"family":"Meyer","given":"Grant","email":"","middleInitial":"A.","affiliations":[{"id":7164,"text":"Department of Biology, University of New Mexico, Albuquerque, NM 87131 USA","active":true,"usgs":false}],"preferred":false,"id":442886,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Okubo, Chris 0000-0001-9776-8128 cokubo@usgs.gov","orcid":"https://orcid.org/0000-0001-9776-8128","contributorId":174209,"corporation":false,"usgs":true,"family":"Okubo","given":"Chris","email":"cokubo@usgs.gov","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":442887,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Newsom, Horton E.","contributorId":67689,"corporation":false,"usgs":false,"family":"Newsom","given":"Horton","email":"","middleInitial":"E.","affiliations":[{"id":13339,"text":"University of New Mexico, Albuquerque","active":true,"usgs":false}],"preferred":false,"id":442885,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wiens, Roger C.","contributorId":80203,"corporation":false,"usgs":true,"family":"Wiens","given":"Roger C.","affiliations":[],"preferred":false,"id":442888,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Nutrient concentration and flux in the Mississippi River have increased substantially over the last century because of changes in land use, climate, hydrology, and river management and engineering. As in other large floodplain rivers, rates of processes that cycle nitrogen and phosphorus in the UMR exhibit pronounced spatial and temporal heterogeneity because of the complex morphology of the river. This spatial variability in nutrient processing creates clear spatial patterns in nutrient concentrations. For example, nitrate concentrations generally are much lower in off-channel areas than in the main channel. The specifics of in-river nutrient cycling and the effects of high rates of nutrient input on UMR have been less studied than the factors affecting nutrient input to the river and transport to the Gulf of Mexico, and important questions concerning nutrient cycling in the UMR remain. Eutrophication and resulting changes in river productivity have only recently been investigated the UMR. These recent studies indicate that the high nutrient concentrations in the river may affect community composition of aquatic vegetation (e. g., the abundance of filamentous algae and duckweeds), dissolved oxygen concentrations in off-channel areas, and the abundance of cyanobacteria. Actions to reduce nutrient input to the river include changes in land-use practices, wetland restoration, and hydrological modifications to the river. Evidence suggests that most of the above methods can contribute to reducing nutrient concentration in, and transport by, the UMR, but the impacts of mitigation efforts will likely be only slowly realized. ??

All those locations that showed an increase in landsliding were located along rivers and/or roads.

We assessed the impacts of construction of a segment of Corridor H, a four-lane highway, in the Lost River watershed, West Virginia, by monitoring benthic macroinvertebrate communities and water quality, before, during, and after highway construction and prior to highway use at upstream and downstream sites from 1997 through 2007. Data analysis of temporal impacts of highway construction followed a Before-After-Control-Impact (BACI) study design. Highway construction impacts included an increase in stream sedimentation during the construction phase. This was indicated by an increase in turbidity and total suspended solids. Benthic macroinvertebrate metrics indicated a community more tolerant during and after construction than in the period before construction. The percent of Chironomidae and the Hilsenhoff Biotic Index (HBI) increased, while percent of Ephemeroptera, Plecoptera, and Trichoptera (EPT) decreased. Our 10-year study addressed short-term impacts of highway construction and found that impacts were relatively minimal. A recovery of the number of EPT taxa collected after construction indicated that the benthic macroinvertebrate community may be recovering from impacts of highway construction. However, this study only addressed a period of 3 years before, 3 years during, and 4 years post construction. Inferences cannot be made concerning the long-term impacts of the highway, highway traffic, runoff, and other factors associated with highway use. Continual monitoring of the watershed is necessary to determine if the highway has a continual impact on stream habitat, water quality, and biotic integrity. ?? 2010 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10750-009-0070-9","issn":"00188158","usgsCitation":"Hedrick, L.B., Welsh, S., Anderson, J.T., Lin, L., Chen, Y., and Wei, X., 2010, Response of benthic macroinvertebrate communities to highway construction in an Appalachian watershed: Hydrobiologia, v. 641, no. 1, p. 115-131, https://doi.org/10.1007/s10750-009-0070-9.","startPage":"115","endPage":"131","numberOfPages":"17","costCenters":[],"links":[{"id":216687,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-009-0070-9"},{"id":244572,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"641","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-01-12","publicationStatus":"PW","scienceBaseUri":"505aaa35e4b0c8380cd861e4","contributors":{"authors":[{"text":"Hedrick, Lara B.","contributorId":50346,"corporation":false,"usgs":true,"family":"Hedrick","given":"Lara","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":443852,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Welsh, S.A. 0000-0003-0362-054X","orcid":"https://orcid.org/0000-0003-0362-054X","contributorId":10191,"corporation":false,"usgs":true,"family":"Welsh","given":"S.A.","affiliations":[],"preferred":false,"id":443850,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anderson, James T.","contributorId":28071,"corporation":false,"usgs":false,"family":"Anderson","given":"James","email":"","middleInitial":"T.","affiliations":[{"id":12432,"text":"West Virginia University","active":true,"usgs":false}],"preferred":false,"id":443851,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lin, L.-S.","contributorId":66093,"corporation":false,"usgs":true,"family":"Lin","given":"L.-S.","email":"","affiliations":[],"preferred":false,"id":443854,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chen, Y.","contributorId":7019,"corporation":false,"usgs":true,"family":"Chen","given":"Y.","email":"","affiliations":[],"preferred":false,"id":443849,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Wei, X.","contributorId":50636,"corporation":false,"usgs":true,"family":"Wei","given":"X.","email":"","affiliations":[],"preferred":false,"id":443853,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Black bears selected areas occupied by brown bears during spring which may be related to spatially restricted (i.e., restricted to low elevations) but dispersed or patchy availability of food. In contrast, black bears avoided areas occupied by brown bears during summer. Brown bears selected areas near salmon streams during summer, presumably to access spawning salmon. Use of areas with high berry production by black bears during summer appeared in response to avoidance of areas containing brown bears. Berries likely provided black bears a less nutritious, but adequate food source. We suggest that during summer, black bears were displaced by brown bears, which supports distribution theory in that black bears appeared to be partially constrained from areas containing salmon, resulting in their use of areas containing less nutritious forage. Spatial segregation of brown and American black bears apparently occurs when high-quality resources are spatially restricted and alternate resources are available to the subordinate species.

In order to assess social vulnerability to Cascadia tsunamis, we adjust a social vulnerability index based on principal component analysis first developed by Cutter et al. (2003) to operate at the census-block level of geography and focus on community-level comparisons along the Oregon coast. The number of residents from blocks in tsunami-prone areas considered to have higher social vulnerability varies considerably among 26 Oregon cities and most are concentrated in four cities and two unincorporated areas. Variations in the number of residents from census blocks considered to have higher social vulnerability in each city do not strongly correlate with the number of residents or city assets in tsunami-prone areas. Methods presented here will help emergency managers to identify community sub-groups that are more susceptible to loss and to develop risk-reduction strategies that are tailored to local conditions. ?? z.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Natural Hazards","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11069-009-9376-1","issn":"0921030X","usgsCitation":"Wood, N., Burton, C., and Cutter, S., 2010, Community variations in social vulnerability to Cascadia-related tsunamis in the U.S. Pacific Northwest: Natural Hazards, v. 52, no. 2, p. 369-389, https://doi.org/10.1007/s11069-009-9376-1.","startPage":"369","endPage":"389","numberOfPages":"21","costCenters":[],"links":[{"id":475863,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s11069-009-9376-1","text":"Publisher Index Page"},{"id":216751,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11069-009-9376-1"},{"id":244637,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"2","noUsgsAuthors":false,"publicationDate":"2009-03-26","publicationStatus":"PW","scienceBaseUri":"5059f80be4b0c8380cd4ce4d","contributors":{"authors":[{"text":"Wood, N.J.","contributorId":7900,"corporation":false,"usgs":true,"family":"Wood","given":"N.J.","email":"","affiliations":[],"preferred":false,"id":443866,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burton, C.G.","contributorId":88582,"corporation":false,"usgs":true,"family":"Burton","given":"C.G.","email":"","affiliations":[],"preferred":false,"id":443867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cutter, S.L.","contributorId":96515,"corporation":false,"usgs":true,"family":"Cutter","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":443868,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Environmental models have been developed to predict the spread of introgression, but few studies have assessed the role of propagule pressure. We used an extensive set of fish stocking records and geographic information system (GIS) data to produce a spatially explicit index of potential propagule pressure exerted by introduced rainbow trout in the Upper Kootenay River, British Columbia, Canada. We then used logistic regression and the information-theoretic approach to test the ability of a set of environmental and spatial variables to predict the level of introgression between native westslope cutthroat trout and introduced rainbow trout. Introgression was assessed using between four and seven co-dominant, diagnostic nuclear markers at 45 sites in 31 different streams. The best model for predicting introgression included our GIS propagule pressure index and an environmental variable that accounted for the biogeoclimatic zone of the site (r<sup>2</sup> = 0.62). This model was 1.4 times more likely to explain introgression than the next-best model, which consisted of only the propagule pressure index variable. We created a composite model based on the model-averaged results of the seven top models that included environmental, spatial, and propagule pressure variables. The propagule pressure index had the highest importance weight (0.995) of all variables tested and was negatively related to sites with no introgression. This study used an index of propagule pressure and demonstrated that propagule pressure had the greatest influence on the level of introgression between a native and introduced trout in a human-induced hybrid zone. ?? 2010 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-0441.1","issn":"10510761","usgsCitation":"Bennett, S., Olson, J., Kershner, J.L., and Corbett, P., 2010, Propagule pressure and stream characteristics influence introgression: Cutthroat and rainbow trout in British Columbia: Ecological Applications, v. 20, no. 1, p. 263-277, https://doi.org/10.1890/08-0441.1.","startPage":"263","endPage":"277","numberOfPages":"15","costCenters":[],"links":[{"id":216752,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-0441.1"},{"id":244638,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8f14e4b0c8380cd7f588","contributors":{"authors":[{"text":"Bennett, S.N.","contributorId":87784,"corporation":false,"usgs":true,"family":"Bennett","given":"S.N.","email":"","affiliations":[],"preferred":false,"id":443870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Olson, J.R.","contributorId":98976,"corporation":false,"usgs":true,"family":"Olson","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":443871,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kershner, J.

Other dusty areas near the volcanoes and elsewhere on the planet exhibit a similar morphology. The material composing these \"reticulate\" bedforms is constrained by their remote sensing properties and the threshold curve combined with the saltation/suspension boundary, both of which vary as a function of elevation (atmospheric pressure), particle size, and particle composition. Considering all of these factors, dust aggregates are the most likely material composing these bedforms. We propose that airfall dust on and near the volcanoes aggregates in situ over time, maybe due to electrostatic charging followed by cementation by salts. The aggregates eventually reach a particle size at which saltation is possible. Aggregates on the flanks are transported downslope by katabatic winds and form linear and \"accordion\" morphologies. Materials within the calderas and other depressions remain trapped and are subjected to multidirectional winds, forming an interlinked \"honeycomb\" texture.

When the reactor is pressurized with CH<sub>4</sub> gas without external heating, methane hydrate can be formed from ice grains with yields up to 25% under otherwise static conditions. The rapid temperature rise caused by pressurization partially melts the granular ice, which reacts with methane to form hydrate rinds around the ice grains. The heat generated by the exothermic reaction of methane hydrate formation buffers the sample temperature near the melting point of ice for enough time to allow for continuous hydrate growth at high rates. Surprisingly, faster rates and higher yields of methane hydrate were found in runs with lower initial temperatures, slower rates of pressurization, higher porosity of the granular ice samples, or mixtures with sediments. The addition of ethanol also dramatically enhanced the formation of polycrystalline MGH. This study demonstrates that polycrystalline MGH with varied physical properties suitable for different laboratory tests can be manufactured by controlling synthesis procedures or parameters. Subsequent dissociation experiments using a gas collection apparatus and flowmeter confirmed high methane saturation (CH <sub>4</sub>&middot;<sub>2</sub>O, with n = 5.82 &plusmn; 0.03) in the MGH. Dissociation rates of the various samples synthesized at diverse conditions may be fitted to different rate laws, including zero and first order.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Energy and Fuels","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ACS Publications","doi":"10.1021/ef901403r","issn":"08870624","usgsCitation":"Chen, P., Huang, W., and Stern, L.A., 2010, Methane hydrate synthesis from ice: Influence of pressurization and ethanol on optimizing formation rates and hydrate yield: Energy and Fuels, v. 24, no. 4, p. 2390-2403, https://doi.org/10.1021/ef901403r.","productDescription":"14 p.","startPage":"2390","endPage":"2403","numberOfPages":"14","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":216643,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/ef901403r"},{"id":244526,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-03-22","publicationStatus":"PW","scienceBaseUri":"505a552ae4b0c8380cd6d153","contributors":{"authors":[{"text":"Chen, Po-Chun.","contributorId":48413,"corporation":false,"usgs":true,"family":"Chen","given":"Po-Chun.","email":"","affiliations":[],"preferred":false,"id":445325,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Huang, Wuu-Liang","contributorId":74597,"corporation":false,"usgs":true,"family":"Huang","given":"Wuu-Liang","email":"","affiliations":[],"preferred":false,"id":445326,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stern, Laura A. 0000-0003-3440-5674 lstern@usgs.gov","orcid":"https://orcid.org/0000-0003-3440-5674","contributorId":1197,"corporation":false,"usgs":true,"family":"Stern","given":"Laura","email":"lstern@usgs.gov","middleInitial":"A.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":445324,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In addition to providing some examples of color images and their interpretation, we describe the processing techniques used to produce them and note some of the minor artifacts in the output. We also provide an example of how HiRISE color products can be effectively used to expand mineral and lithologic mapping provided by CRISM data products that are backed by other spectral datasets.

Nine of these taxa are described as new species using light and scanning electron microscopy. Comments are made on their systematic position and how they are distinguished from other species in the genus. Additionally, two previously unrecognized taxa within the genus were discovered in samples from South Africa. One of these, Muelleria taylorii Van de Vijver & Cocquyt sp. nov., is new to science; the other, Muelleria vandermerwei (Cholnoky) Van de Vijver & Cocquyt nov. comb., had been included in the genus Diploneis. The large number of new Muelleria taxa on the (sub)-Antarctic locations is not surprising. Species in Muelleria occur rarely in collections; in many habitats, it is unusual to find more than 1-2 valves in any slide preparation. As a result, records are scarce. The practice of \"force-fitting\" (shoehorning) specimens into descriptions from common taxonomic keys (and species drift) results in European species, such as M. gibbula and M. linearis, being applied to Antarctic forms in ecological studies. Finally, the typical terrestrial habitats of soils, mosses and ephemeral water bodies of most of these taxa have been poorly studied in the past.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Phycologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2216/09-27.1","issn":"00318884","usgsCitation":"Van De Vijver, B., Mataloni, G., Stanish, L., and Spaulding, S., 2010, New and interesting species of the genus Muelleria (Bacillariophyta) from the Antarctic region and South Africa: Phycologia, v. 49, no. 1, p. 22-41, https://doi.org/10.2216/09-27.1.","startPage":"22","endPage":"41","numberOfPages":"20","costCenters":[],"links":[{"id":476044,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11336/53537","text":"External Repository"},{"id":244605,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216719,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2216/09-27.1"}],"volume":"49","issue":"1","noUsgsAuthors":false,"publicationDate":"2019-03-27","publicationStatus":"PW","scienceBaseUri":"505a6553e4b0c8380cd72b72","contributors":{"authors":[{"text":"Van De Vijver, B.","contributorId":19782,"corporation":false,"usgs":true,"family":"Van De Vijver","given":"B.","affiliations":[],"preferred":false,"id":444033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mataloni, G.","contributorId":67756,"corporation":false,"usgs":true,"family":"Mataloni","given":"G.","affiliations":[],"preferred":false,"id":444035,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stanish, L.","contributorId":31232,"corporation":false,"usgs":true,"family":"Stanish","given":"L.","affiliations":[],"preferred":false,"id":444034,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Spaulding, S.

Known Hg emission sources within the airshed of the monitoring sites include: 1) a 1114 megawatt (MW) coal-fired electric utility generating station; 2) a Hg-bed chlor-alkali plant; and 3) a smaller (465 MW) coal-burning electric utility. Monitoring sites, showing sporadic elevation of RGM, Hg<sup>o</sup> and Hg-PM <sub>2.5</sub>, were positioned at distances of 25, 50 and 100 km northward of the larger electric utility. A series of RGM events were recorded at each site. The largest, on 23 September, occurred under prevailing southerly winds, with a maximum RGM value (56.8 pg m<sup>-3</sup>) measured at the 100 km site, and corresponding elevated SO<sub>2</sub> (10.41 ppbv; measured at 50 km site). The finding that RGM, Hg<sup>o</sup>, and Hg-PM<sub>2.5</sub> are not always highest at the 25 km site, closest to the large generating station, contradicts the idea that RGM decreases with distance from a large point source. This may be explained if: 1) the 100 km site was influenced by emissions from the chlor-alkali facility or by RGM from regional urban sources; 2) the emission stack height of the larger power plant promoted plume transport at an elevation where the Hg is carried over the closest site; or 3) RGM was being generated in the plume through oxidation of Hg<sup>o</sup>.

We investigated how wildfire interacts with annual variations in peak streamflow to affect the stability of stream macroinvertebrate communities in a central Idaho wilderness, USA. We conducted a 4-year retrospective analysis of unburned (n = 7) and burned (n = 6) catchments, using changes in reflectance values (??NBR) from satellite imagery to quantify the percentage of each catchment's riparian and upland vegetation that burned at high and low severity. For this wildland fire complex, increasing riparian burn severity and extent were associated with greater year-to-year variation, rather than a perennial increase, in sediment loads, organic debris, large woody debris (LWD) and undercut bank structure. Temporal changes in these variables were correlated with yearly peak flow in burned catchments but not in unburned reference catchments, indicating that an interaction between fire and flow can result in decreased habitat stability in burned catchments. Streams in more severely burned catchments exhibited increasingly dynamic macroinvertebrate communities and did not show increased similarity to reference streams over time. Annual variability in macroinvertebrates was attributed, predominantly, to the changing influence of sediment, LWD, riparian cover and organic debris, as quantities of these habitat components fluctuated annually depending on burn severity and annual peak streamflows. These analyses suggest that interactions among fire, flow and stream habitat may increase inter-annual habitat variability and macroinvertebrate community dynamics for a duration approaching the length of the historic fire return interval of the study area. ?? 2009 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2427.2009.02275.x","issn":"00465070","usgsCitation":"Arkle, R., Pilliod, D., and Strickler, K., 2010, Fire, flow and dynamic equilibrium in stream macroinvertebrate communities: Freshwater Biology, v. 55, no. 2, p. 299-314, https://doi.org/10.1111/j.1365-2427.2009.02275.x.","startPage":"299","endPage":"314","numberOfPages":"16","costCenters":[],"links":[{"id":244455,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216577,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2427.2009.02275.x"}],"volume":"55","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-01-13","publicationStatus":"PW","scienceBaseUri":"505a1049e4b0c8380cd53be5","contributors":{"authors":[{"text":"Arkle, R.S.","contributorId":86997,"corporation":false,"usgs":true,"family":"Arkle","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":444449,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pilliod, D.

To investigate patterns of parasitism, we trapped rats and quantified nematodes on 13 islets of various sizes and habitat types. Most rats were parasitized (59) with an average of 12 worms per infected rat. Islet size did not greatly influence parasite population biology. Nematodes also did not appear to affect rat condition (weight to skull length). The only strong and consistent factor associated with the mean abundance of nematodes in rats was habitat (dominant cover and locally dominant plant species). Thus, nematodes were much more abundant in rats from sites dominated by coconut trees (Cocos nucifera). Coconut trees may also be an introduced species at Palmyra Atoll. ??

A resurgence of lake trout </span><i>Salvelinus namaycush</i><span> reproduction in Lake Huron following the crash of alewife stocks between 2002 and 2004 provided an opportunity to evaluate the relative effects of this crash on reproduction through relief from either alewife mediated thiamine deficiency or alewife predation on larval lake trout relative to possible changes in the size of the lake trout spawning stock.

Although thiamine levels for lake trout collected at a second reef in Parry Sound did not change post-crash, levels both pre- and post-crash were consistent with a rainbow smelt diet. A reef specific fry emergence index was found to be positively related to reef specific egg thiamine concentration but negatively related to reef specific occurrence of EMS, a thiamine deficiency related mortality syndrome. We found little evidence for overlap between the timing of spring shoreward migration of alewives and lake trout emergence, suggesting that relief from alewife predation effects had relatively little effect on the observed increase in lake trout recruitment. Numbers of spawners in the north, north-central, and southern zones of the lake increased from 2000 onwards. Overall the abundance post-2003 was higher than from pre-2004, suggesting that spawner abundance may also have contributed to increased lake trout reproduction. However, predicted numbers of spawners and measured abundance of wild recruits in assessment gear were poorly correlated suggesting that the increase in reproduction was not totally spawner dependent and hence relief from thiamine deficiency was also likely involved. We conclude from this that eliminating the effects of an alewife diet mediated thiamine deficiency can have positive effects on lake trout reproduction but more research is required to understand the effect of spawner number and the role of spawning habitat availability.</span></p>","language":"English","publisher":"Taylor &

Methods: Enzyme assays with acetylcholine esterase were used to analyze serially succussed and diluted (SSD) solutions prepared in glass and plastic containers. Aqueous SSD preparations starting with various solutes, or water alone, were prepared under several conditions, and tested for their solute content and their ability to affect enzyme stability in dilute solution. Results: We confirm that water acts to dissolve constituents from glass vials, and show that the solutes derived from the glass have effects on enzymes in the resultant solutions. Enzyme assays demonstrated that enzyme stability in purified and deionized water was enhanced in SSD solutions that were prepared in glass containers, but not those prepared in plastic. The increased enzyme stability could be mimicked in a dose-dependent manner by the addition of silicates to the purified, deionized water that enzymes were dissolved in. Elemental analyses of SSD water preparations made in glass vials showed that boron, silicon, and sodium were present at micromolar concentrations. Conclusions: These results show that silicates and other solutes are present at micromolar levels in all glass-exposed solutions, whether pharmaceutical or homeopathic in nature. Even though silicates are known to have biological activity at higher concentrations, the silicate concentrations we measured in homeopathic preparations were too low to account for any purported in vivo efficacy, but could potentially influence in vitro biological assays reporting homeopathic effects. ?? 2009 The Faculty of Homeopathy.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Homeopathy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.homp.2009.11.006","issn":"14754916","usgsCitation":"Ives, J., Moffett, J., Arun, P., Lam, D., Todorov, T., Brothers, A., Anick, D., Centeno, J., Namboodiri, M., and Jonas, W., 2010, Enzyme stabilization by glass-derived silicates in glass-exposed aqueous solutions: Homeopathy, v. 99, no. 1, p. 15-24, https://doi.org/10.1016/j.homp.2009.11.006.","startPage":"15","endPage":"24","numberOfPages":"10","costCenters":[],"links":[{"id":214185,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.homp.2009.11.006"},{"id":241879,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a09f6e4b0c8380cd52123","contributors":{"authors":[{"text":"Ives, J.A.","contributorId":64901,"corporation":false,"usgs":true,"family":"Ives","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":443181,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moffett, J.R.","contributorId":36767,"corporation":false,"usgs":true,"family":"Moffett","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":443179,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arun, P.","contributorId":24581,"corporation":false,"usgs":true,"family":"Arun","given":"P.","email":"","affiliations":[],"preferred":false,"id":443176,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lam, D.","contributorId":96102,"corporation":false,"usgs":true,"family":"Lam","given":"D.","email":"","affiliations":[],"preferred":false,"id":443183,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Todorov, T.I.","contributorId":10995,"corporation":false,"usgs":true,"family":"Todorov","given":"T.I.","email":"","affiliations":[],"preferred":false,"id":443175,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brothers, A.B.","contributorId":77751,"corporation":false,"usgs":true,"family":"Brothers","given":"A.B.","email":"","affiliations":[],"preferred":false,"id":443182,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Anick, D.J.","contributorId":25774,"corporation":false,"usgs":true,"family":"Anick","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":443177,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Centeno, J.","contributorId":103481,"corporation":false,"usgs":true,"family":"Centeno","given":"J.","email":"","affiliations":[],"preferred":false,"id":443184,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Namboodiri, M.A.A.","contributorId":34732,"corporation":false,"usgs":true,"family":"Namboodiri","given":"M.A.A.","email":"","affiliations":[],"preferred":false,"id":443178,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Jonas, W.B.","contributorId":42442,"corporation":false,"usgs":true,"family":"Jonas","given":"W.B.","email":"","affiliations":[],"preferred":false,"id":443180,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

It is useful for unsaturated flow processes that are not inherently diffusive, or that do not progress through a series of equilibrium states. The term source-responsive is used to mean that flow responds sensitively to changing conditions at the source of water input (e.g., rainfall, irrigation, or ponded infiltration). The domain of preferential flow can be conceptualized as laminar flow in free-surface films along the walls of pores. These films may be considered to have uniform thickness, as suggested by field evidence that preferential flow moves at an approximately uniform rate when generated by a continuous and ample water supply. An effective facial area per unit volume quantitatively characterizes the medium with respect to source-responsive flow. A flow-intensity factor dependent on conditions within the medium represents the amount of source-responsive flow at a given time and position. Laminar flow theory provides relations for the velocity and thickness of flowing source-responsive films. Combination with the Darcy-Buckingham law and the continuity equation leads to expressions for both fluxes and dynamic water contents. Where preferential flow is sometimes or always significant, the interactive combination of source-responsive and diffuse flow has the potential to improve prediction of unsaturated-zone fluxes in response to hydraulic inputs and the evolving distribution of soil moisture. Examples for which this approach is efficient and physically plausible include (i) rainstorm-generated rapid fluctuations of a deep water table and (ii) space- and time-dependent soil water content response to infiltration in a macroporous soil. ??

As part of this effort, we developed a new version of the SLEUTH model (SLEUTH-3r), which introduces new functionality and fit metrics that substantially increase the performance and applicability of the model. In addition, we developed methods that expand the capability of SLEUTH to incorporate economic, cultural and policy information, opening up new avenues for the integration of SLEUTH with other land-change models. SLEUTH-3r is also more computationally efficient (by a factor of 5) and uses less memory (reduced 65%) than the original software. With the new version of SLEUTH, we were able to achieve high accuracies at both the aggregate level of 15 sub-regional modeling units and at finer scales. We present forecasts to 2030 of urban development under a current trends scenario across the entire Chesapeake Bay drainage basin, and three alternative scenarios for a sub-region within the Chesapeake Bay watershed to illustrate the new ability of SLEUTH-3r to generate forecasts across a broad range of conditions.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.compenvurbsys.2009.08.003","usgsCitation":"Jantz, C.A., Goetz, S., Donato, D.I., and Claggett, P.R., 2010, Designing and implementing a regional urban modeling system using the SLEUTH cellular urban model: Computers, Environment and Urban Systems, v. 34, no. 1, p. 1-16, https://doi.org/10.1016/j.compenvurbsys.2009.08.003.","productDescription":"16 p.","startPage":"1","endPage":"16","costCenters":[],"links":[{"id":242168,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ff46e4b0c8380cd4f0e5","contributors":{"authors":[{"text":"Jantz, Claire A.","contributorId":107477,"corporation":false,"usgs":false,"family":"Jantz","given":"Claire","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":442412,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goetz, Scott J.","contributorId":22232,"corporation":false,"usgs":true,"family":"Goetz","given":"Scott J.","affiliations":[],"preferred":false,"id":442410,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Donato, David I. 0000-0002-5412-0249 didonato@usgs.gov","orcid":"https://orcid.org/0000-0002-5412-0249","contributorId":2234,"corporation":false,"usgs":true,"family":"Donato","given":"David","email":"didonato@usgs.gov","middleInitial":"I.","affiliations":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":442411,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Claggett, Peter R. 0000-0002-5335-2857 pclaggett@usgs.gov","orcid":"https://orcid.org/0000-0002-5335-2857","contributorId":176287,"corporation":false,"usgs":true,"family":"Claggett","given":"Peter","email":"pclaggett@usgs.gov","middleInitial":"R.","affiliations":[{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true},{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":442409,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
