Movement was rare among eight populations separated by only a few hundred meters: seven years of twice-annual sampling captured &gt;1200 individuals but only 26 interpopulation dispersers. We developed a program that implemented models with parameters for capture, survival, and interpopulation movement probability and that evaluated competing hypotheses in a model selection framework. We evaluated variants of the island, stepping-stone, and isolation-by-distance models of interpopulation movement, incorporating effects of age, season, and habitat (short or tall grass). For both sexes, QAICc values clearly favored isolation-by-distance models, or models combining the effects of isolation by distance and habitat. Models with probability of dispersal expressed as linear-logistic functions of distance and as negative exponentials of distance fit the data equally well. Interpopulation movement probabilities were similar among sexes (perhaps slightly biased toward females), greater for juveniles than adults (especially for females), and greater before than during the breeding season (especially for females). These patterns resemble those previously described for within-population dispersal in this species, which we interpret as indicating that the same processes initiate both within- and between-population dispersal.</p>","language":"English","publisher":"Wiley","doi":"10.1890/03-0599","usgsCitation":"Skvarla, J., Nichols, J., Hines, J., and Waser, P., 2004, Modeling interpopulation dispersal by banner-tailed kangaroo rats: Ecology, v. 85, no. 10, p. 2737-2746, https://doi.org/10.1890/03-0599.","productDescription":"10 p.","startPage":"2737","endPage":"2746","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":234096,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5c06e4b0c8380cd6f997","contributors":{"authors":[{"text":"Skvarla, J.L.","contributorId":68935,"corporation":false,"usgs":true,"family":"Skvarla","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":410172,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":410169,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hines, J.E. 0000-0001-5478-7230","orcid":"https://orcid.org/0000-0001-5478-7230","contributorId":36885,"corporation":false,"usgs":true,"family":"Hines","given":"J.E.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":410170,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Waser, P.M.","contributorId":66454,"corporation":false,"usgs":true,"family":"Waser","given":"P.M.","affiliations":[],"preferred":false,"id":410171,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

On the open-coast intertidal flats of the Changjiang Delta large laterally migrating tidal channels are absent. Instead, numerous shallow tidal creeks cut across the intertidal flats. On these flats, vertical rather than lateral migration dominates sedimentation. Observations over semidiurnal tidal cycles show that both flood and ebb tides have the potential to deposit their own mud-sand couplets, but four couplets per day are rarely preserved. Reworking by tidal currents and/or weak waves results in loss of tidal couplets or amalgamation of two or more thin couplets into a single thick couplet. Measurements of preserved couplets show that they can represent a single flooding or ebbing event (half day) to a period of several neap-spring cycles. Diastems within amalgamated couplets are generally not distinguishable. The key agent for reworking open-coast intertidal flat deposits is not tidal creek migration but seasonal storm waves. Seasonal storm deposits consist of a basal scour and sand-dominant laminae with mud pebbles, grading upward to mud-dominated layers of fair-weather deposits. Sand-dominated layers are also reworked.","largerWorkTitle":"Journal of Coastal Research","language":"English","issn":"07490208","usgsCitation":"Fan, D., Li, C., Wang, D., Wang, P., Archer, A., and Greb, S., 2004, Morphology and sedimentation on open-coast intertidal flats of the Changjiang Delta, China, <i>in</i> Journal of Coastal Research, no.

This capability is suited for the development of databases appropriate for water modeling. However, it is rare for GIS to provide direct inputs to the models. To demonstrate the logical procedure of coupling GIS for model parameter extraction, we selected the Agricultural Non-Point Source (AGNPS) pollution model. Investigators can generate data layers at various resolutions and resample to pixel sizes to support models at particular scales. We developed databases of elevation, land cover, and soils at various resolutions in four watersheds. The ability to use multiresolution databases for the generation of model parameters is problematic for grid-based models. We used database development procedures and observed the effects of resolution and resampling on GIS input datasets and parameters generated from those inputs for AGNPS. Results indicate that elevation values at specific points compare favorably between 3- and 30-m raster datasets. Categorical data analysis indicates that land cover classes vary significantly. Derived parameters parallel the results of the base GIS datasets. Analysis of data resampled from 30-m to 60-, 120-, 210-, 240-, 480-, 960-, and 1920-m pixels indicates a general degradation of both elevation and land cover correlations as resolution decreases. Initial evaluation of model output values for soluble nitrogen and phosphorous indicates similar degradation with resolution. ??

However, the ecological, social, and economic consequences of cutthroat trout declines and replacement by non-native salmonid species are relatively minor, and measurable affects on ecosystem function are rare. Restoration efforts for cutthroat trout involve removal or control of bioinvasive salmonid species, but such efforts are costly, ongoing, and resisted frequently by segments of society. Cutthroat trout declines are of little concern to much of the public because they are valued similarly to non-native salmonids, and non-native salmonid species frequently have higher recreational values. Due to the low values placed on cutthroat trout relative to non-native salmonid species, net economic benefits of preserving cutthroat trout are equal to or less than those for non-native salmonids. Cutthroat trout provide a classic case of the consequences of biological invasion; however, other native species are faced with similar issues. We suggest that management agencies establish realistic goals to preserve native species within the context of ecological, social, and economic issues. ?? 2004 Elsevier Ltd.

Using an existing design-based sampling grid on which epiphytic macrolichens had been inventoried in the Northwest Forest Plan area of the U.S. Pacific Northwest, we (1) estimate frequencies and standard errors for each of 25 lichen species having special management designation (i.e., Survey and Manage), (2) assess the probability that individual species were associated with specific land allocation and forest stand age classifications, and (3) provide estimates of sample sizes necessary to ensure sufficient detections for these analyses. We conclude with a discussion of management and conservation information needs that extant data can satisfy and identify advantages and limitations of random vs. nonrandom sampling strategies. Combining design-assisted and model-assisted approaches can overcome some of the limitations of either single strategy.","language":"English","publisher":"Wiley","doi":"10.1890/02-5236","usgsCitation":"Edwards, T., Cutler, D., Geiser, L., Alegria, J., and McKenzie, D., 2004, Assessing rarity of species with low detectability: Lichens in Pacific Northwest forests: Ecological Applications, v. 14, no. 2, p. 414-424, https://doi.org/10.1890/02-5236.","productDescription":"11 p.","startPage":"414","endPage":"424","costCenters":[{"id":609,"text":"Utah Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":235077,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California, Oregon, Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.62890625,\n              46.92025531537451\n            ],\n            [\n              -124.365234375,\n              44.213709909702054\n            ],\n            [\n              -124.892578125,\n              42.61779143282346\n            ],\n            [\n              -124.71679687499999,\n              41.178653972331674\n            ],\n            [\n              -124.365234375,\n              38.06539235133249\n            ],\n            [\n              -123.04687499999999,\n              37.43997405227057\n            ],\n            [\n              -122.08007812499999,\n              37.64903402157866\n            ],\n            [\n              -121.201171875,\n              44.08758502824516\n            ],\n            [\n              -120.9375,\n              49.095452162534826\n            ],\n            [\n              -125.068359375,\n              49.095452162534826\n            ],\n            [\n              -124.62890625,\n              46.92025531537451\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"14","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eddee4b0c8380cd49a76","contributors":{"authors":[{"text":"Edwards, T.C.

In this study, we compared the relative abundance of microhabitat features (the scale at which individual fish associate with seafloor habitat) inside and outside of a large fishery closed area (6917 km<sup>2</sup>) on Georges Bank. Starting in late 1994, the closed area excluded all bottom tending fishing gear capable of capturing demersal fishes. A total of 32 stations were selected inside and outside of the closed area in sand habitats. Video and still photographic transects were conducted at each station using the Seabed Observation and Sampling System (SEABOSS). Seven common (i.e. featureless sand, rippled sand, sand with emergent fauna, bare gravelly sand, gravelly sand with attached-erect fauna, whole shell, shell fragment) and 2 rare (sponges, biogenic depressions) microhabitat types were compared separately. Results showed significant differences in the relative abundance of the shell fragment and sponge microhabitat types between fished and unfished areas. The lack of differences for the other microhabitats may indicate that the level of fishing activity in the area is matched by the system's ability to recover.","largerWorkTitle":"Marine Ecology Progress Series","language":"English","doi":"10.3354/meps269061","issn":"01718630","usgsCitation":"Lindholm, J., Auster, P., and Valentine, P., 2004, Role of a large marine protected area for conserving landscape attributes of sand habitats on Georges Bank (NW Atlantic): Marine Ecology Progress Series, v. 269, p. 61-68, https://doi.org/10.3354/meps269061.","productDescription":"8 p.","startPage":"61","endPage":"68","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":478293,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps269061","text":"Publisher Index Page"},{"id":235078,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Georges Bank","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.77392578125,\n              37.92686760148135\n            ],\n            [\n              -62.1826171875,\n              37.92686760148135\n            ],\n            [\n              -62.1826171875,\n              42.50450285299051\n            ],\n            [\n              -70.77392578125,\n              42.50450285299051\n            ],\n            [\n              -70.77392578125,\n              37.92686760148135\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"269","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aae3ce4b0c8380cd87054","contributors":{"authors":[{"text":"Lindholm, J.","contributorId":7052,"corporation":false,"usgs":true,"family":"Lindholm","given":"J.","email":"","affiliations":[],"preferred":false,"id":411623,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Auster, P.","contributorId":68614,"corporation":false,"usgs":true,"family":"Auster","given":"P.","email":"","affiliations":[],"preferred":false,"id":411624,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Valentine, P.","contributorId":83409,"corporation":false,"usgs":true,"family":"Valentine","given":"P.","affiliations":[],"preferred":false,"id":411625,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We compare data from similar greenschist-facies sequences of bimodal volcanic and subvolcanic rocks associated with carbonaceous and siliciclastic marine sedimentary rocks, in the Wood River area of the Alaska Range and the Salcha River area of the Yukon-Tanana Upland, and from amphibolite-facies augen gneiss and mafic gneiss (amphibolite) in the Goodpaster River area of the upland. Allowing for analytical uncertainties, igneous crystallization age ranges of 376–353 Ma, 378–346 Ma, and 374–358 Ma are indicated by 13 new SHRIMP U-Pb dates for the Wood River, Salcha River, and Goodpaster River areas, respectively. Bimodal magmatism is indicated by Late Devonian crystallization ages for both augen gneiss (371 ± 3 and 362 ± 4 Ma) and associated orthoamphibolite (369 ± 3 Ma) in the upland and by stratigraphic interleaving of mafic and felsic rocks in the Alaska Range. Metabasites in all three study areas have elevated HFSE (high field strength element) and REE (rare earth element) contents indicative of generation in a within-plate (extensional) tectonic setting. Within-plate trace element signatures also are indicated for peralkaline metarhyolites that host the largest volcanogenic massive sulfide deposits of the Bonnifield district in the Wood River area and for metarhyolite tuff interlayered with the carbonaceous Nasina assemblage, which hosts sedimentary exhalative sulfide occurrences in the Salcha River area. Most of the other felsic metaigneous samples from the Alaska Range and the Yukon-Tanana Upland have geochemical signatures that are similar to those of both average upper continental crust and continental-margin arc rocks generated in thick continental crust. Given the absence in our study areas of intermediate-composition magmatic products generally found in most arcs, and the presence of bimodal magmatism, the alkalic within-plate chemistry of the mafic rocks and some of the felsic rocks, and the widespread occurrence of interlayered carbonaceous sedimentary rocks indicative of deposition within a restricted marine basin or submerged continental margin, we consider it most likely that this prolonged Late Devonian to Early Mississippian magmatic episode resulted from attenuation of the ancient continental margin of western North America, rather than development of an arc, as proposed by many others.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/B25342.1","issn":"00167606","usgsCitation":"Dusel-Bacon, C., Wooden, J.L., and Hopkins, M., 2004, U-Pb zircon and geochemical evidence for bimodal mid-Paleozoic magmatism and syngenetic base-metal mineralization in the Yukon-Tanana terrane, Alaska: Geological Society of America Bulletin, v. 116, no. 7-8, p. 989-1015, https://doi.org/10.1130/B25342.1.","productDescription":"27 p.","startPage":"989","endPage":"1015","numberOfPages":"27","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":235186,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States, Canada","state":"Alaska","otherGeospatial":"Yukon-Tanana terrane  ","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -151.5234375,\n              65.44000165965534\n            ],\n            [\n              -145.1953125,\n              62.95522304515911\n            ],\n            [\n              -134.296875,\n              59.88893689676585\n            ],\n            [\n              -129.28710937499997,\n              59.88893689676585\n            ],\n            [\n              -128.232421875,\n              62.91523303947614\n            ],\n            [\n              -135.703125,\n              66.40795547978848\n            ],\n            [\n              -141.15234374999997,\n              68.07330474079025\n            ],\n            [\n              -148.359375,\n              67.30597574414466\n            ],\n            [\n              -151.5234375,\n              65.44000165965534\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"116","issue":"7-8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb9d2e4b08c986b327e27","contributors":{"authors":[{"text":"Dusel-Bacon, Cynthia 0000-0001-8481-739X cdusel@usgs.gov","orcid":"https://orcid.org/0000-0001-8481-739X","contributorId":2797,"corporation":false,"usgs":true,"family":"Dusel-Bacon","given":"Cynthia","email":"cdusel@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":777768,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wooden, J.

The aquifer, in northeastern Kansas, consists of high porosity, low hydraulic conductivity fine-grained sediments dominated by silt and bounded by fractured limestone and shale bedrock. Results show that the aquifer underwent chemical stratification followed by homogenization three times during the study period. The length of time between maximum stratification and complete homogenization was 3-5 months. The chemical parameters most useful for demonstrating the mixing trends were dissolved nitrate and sulfate. Higher nitrate concentrations were typical of unsaturated zone water and were sourced from fertilizer applied to the cultivated fields on the floodplain. Variations in sulfate concentrations are attributed to dissolution of rare gypsum in limestone bedrock and variable evapoconcentration in the unsaturated zone. The mixing of three chemically different waters (entrained, unsaturated-zone water; water entering the base of the floodplain aquifer; and water in residence before each mixing event) was simulated. The resident water component for each mixing event was a fixed composition based on measured water chemistry in the intermediate part of the aquifer. The entrained water composition was calculated using a measured composition of the shallow part of the aquifer and measurements of soil-water content in the unsaturated zone. The incoming basal water composition and the fractions of each mixing component were fitted to match the measured chemistry at the three levels in the aquifer. A conceptual model for this site explains: (1) rapid water-level rises, (2) water-chemistry changes at all levels in the aquifer coincident with the water-level rises, (3) low measured hydraulic conductivity of the valley fill and apparent lack of preferential flow pathways, (4) minuscule amounts of unsaturated-zone recharge, and (5) dissolved oxygen peaks in the saturated zone lagging water-level peaks. We postulate that rainfall enters fractures in bedrock adjacent to the floodplain. This recharge water moves rapidly through the fractured bedrock into the base of the floodplain aquifer. The recharge event through the bedrock causes a rapid rise in water level in the floodplain aquifer, and the chemistry of the deepest water in the floodplain aquifer changes at that time. The rising water also entrains slow-moving, nitrate-rich, unsaturated-zone water, altering the chemistry of water in the shallow part of the aquifer. Vertical chemical stratification in the aquifer is thus created by the change in water chemistry in the upper and lower parts of the saturated zone. As the water level begins to decline, the aquifer undergoes mixing that eventually results in homogeneous water chemistry. The rise in water level from the recharge event also displaces gas from the unsaturated zone that is then replaced as the water level declines following the recharge event. This new, oxygen-rich vadose-zone air equilibrates rapidly with saturated-zone water, resulting in a dissolved oxygen pulse in the ground water that peaks one-half to 2 months after the water-level peak. This oxygen pulse subsequently declines over a period of 2-6 months. ?? 2003 Elsevier B.V.

The grains show a variety of morphologies, including euhedral grains with conchoidal fractures and pits, and spherical grains with no crystal faces, probably because of abrasion. Inclusions are rare, but one grain contains Ca-Al amphilbole inclusions, and another contains an inclusion of chalcopyrite+bornite+pentlandite+heazlewoodite (Ni3S2) that is considered to have formed by a two-stage process of exsolution and crystallization from a once homogeneous Fe-Cu-Ni sulphide melt. All grains examined are solid solutions of Ru and Os with Ir (2.71-11.76 wt.%) and Pd (0.31-0.66 wt%). Their compositions are similar to laurite from ophiolitic rocks. The compositions show broad negative correlations between Os and Ir, between As and Ir, and between As (0.4-0.74 wt.%) and Se (140 to 240 ppm). Laurite with higher Os contains more Se and less Ir and As. The negative correlations between Se and As may be attributed to their occupancy of the S site, but the compositional variations of Os. Ir and As probably reflect the compositional variation of rocks where the crystals grew. Ratios of S/Se in laurite show a narrow spread from 1380 to 2300, which are similar to ratios for sulphides from the refractory sub-are mantle. Sulphur isotopic compositions of laurite are independent of chemical compositions and morphologies and are similar to the chondritic value of 0???. The data suggest that S in laurite has not undergone redox changes and originated from the refractory mantle. The data support the formation of laurite in the residual mantle or in a magnia generated from such a refractory mantle, followed by erosion after the obduction of the host ultramafic rocks. ?? 2004 The Mineralogical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mineralogical Magazine","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1180/0026461046820192","issn":"0026461X","usgsCitation":"Hattori, K., Cabri, L., Johanson, B., and Zientek, M.L., 2004, Origin of placer laurite from Borneo: Se and As contents, and S isotopic compositions: Mineralogical Magazine, v. 68, no. 2, p. 353-368, https://doi.org/10.1180/0026461046820192.","startPage":"353","endPage":"368","numberOfPages":"16","costCenters":[],"links":[{"id":209075,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1180/0026461046820192"},{"id":235267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"2","noUsgsAuthors":false,"publicationDate":"2018-07-05","publicationStatus":"PW","scienceBaseUri":"505a70ece4b0c8380cd76343","contributors":{"authors":[{"text":"Hattori, K.H.","contributorId":29615,"corporation":false,"usgs":true,"family":"Hattori","given":"K.H.","email":"","affiliations":[],"preferred":false,"id":412749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cabri, L.J.","contributorId":33895,"corporation":false,"usgs":true,"family":"Cabri","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":412750,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johanson, B.","contributorId":24539,"corporation":false,"usgs":true,"family":"Johanson","given":"B.","email":"","affiliations":[],"preferred":false,"id":412748,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zientek, M.

These events result in surprises that cannot easily be predicted based on information obtained at a single scale. Progress on catastrophic events has focused on one of the following two areas: nonlinear dynamics through time without an explicit consideration of spatial connectivity [Holling, C. S. (1992) <i>Ecol. Monogr.</i> 62, 447–502] or spatial connectivity and the spread of contagious processes without a consideration of cross-scale interactions and feedbacks [Zeng, N., Neeling, J. D., Lau, L. M. &amp; Tucker, C. J. (1999) <i>Science</i> 286, 1537–1540]. These approaches rarely have ventured beyond traditional disciplinary boundaries. We provide an interdisciplinary, conceptual, and general mathematical framework for understanding and forecasting nonlinear dynamics through time and across space. We illustrate the generality and usefulness of our approach by using new data and recasting published data from ecology (wildfires and desertification), epidemiology (infectious diseases), and engineering (structural failures). We show that decisions that minimize the likelihood of catastrophic events must be based on cross-scale interactions, and such decisions will often be counterintuitive. Given the continuing challenges associated with global change, approaches that cross disciplinary boundaries to include interactions and feedbacks at multiple scales are needed to increase our ability to predict catastrophic events and develop strategies for minimizing their occurrence and impacts. Our framework is an important step in developing predictive tools and designing experiments to examine cross-scale interactions.</p>","language":"English","publisher":"National Academy of Sciences of the United States of America","doi":"10.1073/pnas.0403822101","usgsCitation":"Peters, D., Pielke, R.A., Bestelmeyer, B.T., Allen, C.D., Munson-McGee, S., and Havstad, K.M., 2004, Cross scale interactions, nonlinearities, and forecasting catastrophic events: PNAS, v. 101, no. 42, p. 15130-15135, https://doi.org/10.1073/pnas.0403822101.","productDescription":"6 p.","startPage":"15130","endPage":"15135","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":489984,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/523446","text":"External Repository"},{"id":132401,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"42","noUsgsAuthors":false,"publicationDate":"2004-10-06","publicationStatus":"PW","scienceBaseUri":"4f4e4ad1e4b07f02db680f57","contributors":{"authors":[{"text":"Peters, Debra P.

The objectives of this study were to describe patterns of fish species richness, evenness, and diversity among representative habitats and river reaches and to examine the relationship between fish species richness and habitat diversity. Each year (1994-1999) fish communities of main-channel borders (MCB), side channel borders (SCB), and contiguous backwater shorelines (BWS) were sampled using boat-mounted electrofishing, mini-fyke-nets, tyke nets, hoop nets, and seines at a standardized number of sites. A total of 0.65 million fish were collected, representing 106 species from upper Mississippi River Pools 4, 8, 13, and 26; the open (unimpounded) river reach; and the La Grange Reach of the Illinois River. Within pools, species richness based on rarefaction differed significantly among habitats and was highest in BWS and lowest in MCB (P < 0.0001). At the reach scale, Pools 4, 8, and 13 consistently had the highest species richness and Pool 26, the open-river reach, and the La Grange Reach were significantly lower (P < 0.0001). Species evenness and diversity indices showed similar trends. The relationship between native fish species richness and habitat diversity was highly significant (r(2) = 0.85; P = 0.0091). These results support efforts aimed at the conservation and enhancement of connected side channels and backwaters. Although constrained by dams, pools with high native species richness could serve as a relative reference. The remnants of natural riverine dynamics that remain in these reaches should be preserved and enhanced; conditions could be used to guide restoration activities in more degraded reaches.","language":"English","publisher":"Wiley","doi":"10.1577/T03-089.1","usgsCitation":"Koel, T., 2004, Spatial variation in fish species richness of the upper Mississippi River system: Transactions of the American Fisheries Society, v. 133, no. 4, p. 984-1003, https://doi.org/10.1577/T03-089.1.","productDescription":"20 p.","startPage":"984","endPage":"1003","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":133846,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Iowa, Minnesota, Missouri, Wisconsin","otherGeospatial":"Mississippi River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.13134765625,\n              44.29240108529005\n            ],\n            [\n              -91.47216796874996,\n              43.64402584769947\n            ],\n            [\n              -91.20849609375,\n              42.79540065303723\n            ],\n            [\n              -90.59326171874999,\n              42.309815415686664\n            ],\n            [\n              -90.32958984374999,\n              41.934976500546604\n            ],\n            [\n              -90.48339843749999,\n              41.77131167976407\n            ],\n            [\n              -91.18652343749997,\n              41.29431726315255\n            ],\n            [\n              -91.18652343749999,\n              40.81380923056958\n            ],\n            [\n              -91.66992187499999,\n              40.329795743702064\n            ],\n            [\n              -91.51611328124999,\n              39.774769485295465\n            ],\n            [\n              -91.25244140624999,\n              39.35129035526705\n            ],\n            [\n              -90.57128906249999,\n              38.8225909761771\n            ],\n            [\n              -89.89013671874997,\n              38.56534784488544\n            ],\n            [\n              -90.54931640624999,\n              39.30029918615029\n            ],\n            [\n              -91.23046874999997,\n              40.12849105685408\n            ],\n            [\n              -90.72509765624999,\n              41.178653972331674\n            ],\n            [\n              -89.93408203124999,\n              41.902277040963696\n            ],\n            [\n              -90.90087890624999,\n              42.89206418807337\n            ],\n            [\n              -91.20849609375,\n              43.91372326852401\n            ],\n            [\n              -91.73583984374999,\n              44.41808794374846\n            ],\n            [\n              -92.63671875,\n              44.74673324024678\n            ],\n            [\n              -93.60351562499997,\n              44.88701247981296\n            ],\n            [\n              -92.13134765625,\n              44.29240108529005\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"133","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db635341","contributors":{"authors":[{"text":"Koel, T.M.","contributorId":10765,"corporation":false,"usgs":true,"family":"Koel","given":"T.M.","affiliations":[],"preferred":false,"id":313106,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Properly managed, these agricultural ponds may effectively increase the total amount of breeding habitat and help to sustain populations. We studied small, constructed agricultural ponds in southeastern Minnesota to assess their value as amphibian breeding sites. Our study examined habitat factors associated with amphibian reproduction at two spatial scales: the pond and the landscape surrounding the pond. We found that small agricultural ponds in southeastern Minnesota provided breeding habitat for at least 10 species of amphibians. Species richness and multispecies reproductive success were more closely associated with characteristics of the pond (water quality, vegetation, and predators) compared with characteristics of the surrounding landscape, but individual species were associated with both pond and landscape variables. Ponds surrounded by row crops had similar species richness and reproductive success compared with natural wetlands and ponds surrounded by nongrazed pasture. Ponds used for watering livestock had elevated concentrations of phosphorus, higher turbidity, and a trend toward reduced amphibian reproductive success. Species richness was highest in small ponds, ponds with lower total nitrogen concentrations, tiger salamanders (<i>Ambystoma tigrinum</i>) present, and lacking fish. Multispecies reproductive success was best in ponds with lower total nitrogen concentrations, less emergent vegetation, and lacking fish. Habitat factors associated with higher reproductive success varied among individual species. We conclude that small, constructed farm ponds, properly managed, may help sustain amphibian populations in landscapes where natural wetland habitat is rare. We recommend management actions such as limiting livestock access to the pond to improve water quality, reducing nitrogen input, and avoiding the introduction of fish.</p>","language":"English","publisher":"Wiley","doi":"10.1890/02-5305","usgsCitation":"Knutson, M.G., Richardson, W.B., Reineke, D., Gray, B., Parmelee, J., and Weick, S., 2004, Agricultural ponds support amphibian populations: Ecological Applications, v. 14, no. 3, p. 669-684, https://doi.org/10.1890/02-5305.","productDescription":"16 p.","startPage":"669","endPage":"684","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":134384,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Minnesota","county":"Houston County, Winona Counties","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.94433593749999,\n              43.42100882994726\n            ],\n            [\n              -92.021484375,\n              43.42100882994726\n            ],\n            [\n              -91.23046875,\n              43.42100882994726\n            ],\n            [\n              -91.2744140625,\n              43.83452678223682\n            ],\n            [\n              -91.49414062499999,\n              44.15068115978094\n            ],\n            [\n              -92.94433593749999,\n              44.465151013519616\n            ],\n            [\n              -92.94433593749999,\n              43.42100882994726\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"14","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48c6e4b07f02db540224","contributors":{"authors":[{"text":"Knutson, M.

None of the rare and extinct species are endemic to Wisconsin, and they represent 7% of the total lichen flora of the state.

Flannelmouth suckers ranging in age from young of the year to 24 years were captured during 1999–2001; their population was estimated as at least 2,286 (95% confidence interval, 1,847–2,998). Recruitment appeared sporadic, consisting of consecutive years of low recruitment (&lt;10%) supplemented by a stronger (31%) year-class. Historically, this native fish was rare and was believed extirpated from the lower river by 1975, but it now reproduces naturally in a reach dramatically altered by water development. This successful reintroduction indicates that one native fish can successfully tolerate environmental alterations whereas another, the razorback sucker <i>Xyrauchen texanus</i>, apparently cannot.

Evidence from the plant taphofacies, floras, and sedimentology of the Morrison is consistent with a warm, seasonal, semi-arid climate throughout, changing from dry semi-arid to humid semi-arid from the Kimmeridgian to the Tithonian parts of the formation. ?? 2004 Published by Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Sedimentary Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.sedgeo.2004.01.004","issn":"00370738","usgsCitation":"Parrish, J.T., Peterson, F., and Turner, C., 2004, Jurassic \"savannah\" - Plant taphonomy and climate of the Morrison Formation (Upper Jurassic, Western USA): Sedimentary Geology, v. 167, no. 3-4, p. 137-162, https://doi.org/10.1016/j.sedgeo.2004.01.004.","startPage":"137","endPage":"162","numberOfPages":"26","costCenters":[],"links":[{"id":478088,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://doc.rero.ch/record/14574/files/PAL_E1788.pdf","text":"External Repository"},{"id":235199,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209030,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.sedgeo.2004.01.004"}],"volume":"167","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a402de4b0c8380cd64b52","contributors":{"authors":[{"text":"Parrish, Judith T.","contributorId":83945,"corporation":false,"usgs":true,"family":"Parrish","given":"Judith","email":"","middleInitial":"T.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":412868,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterson, F.","contributorId":93623,"corporation":false,"usgs":true,"family":"Peterson","given":"F.","email":"","affiliations":[],"preferred":false,"id":412869,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Turner, C.E.","contributorId":45463,"corporation":false,"usgs":true,"family":"Turner","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":412867,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A persistent regional stratigraphy is evident in the mapped area whose geochemistry indicates protoliths consistent with a back-arc marginal basin sequence. The proposed marginal basin may have been floored by an older sialic basement and overlain by a basin-fill sequence consisting of a basal tholeiitic basalt, basic to intermediate volcanic or volcaniclastic rocks and carbonate sediments, a bimodal calc-alkaline volcanic sequence, and finally volcaniclastic, marine, and continental sediments. The presence of high-chlorine biotite and scapolite may indicate circulation of brine fluids or the presence of evaporite layers in the sequence. Abundant, stratabound magnetite deposits with a geologic setting very unlike that of cratonic, Proterozoic banded-iron formations are found throughout the proposed basin sequence. Associated with many of the magnetite deposits is unusual uranium and rare-earth element mineralization. It is proposed here that these deposits formed in an exhalative, volcanogenic, depositional environment within an extensional back-arc marginal basin. Such a tectonic setting is consistent with interpretations of protoliths in other portions of the Reading Prong, the Central Metasedimentary Belt of the Canadian Grenville Province, and recent interpretation of the origin of the Franklin lead-zinc deposits, suggesting a more cohesive evolving arc/back-arc tectonic model for the entire Proterozoic margin of the north-eastern portion of the North American craton.

Fire exclusion also allows fuels to accumulate, and it is unclear how affected populations will respond to the reintroduction of fire. Although white pine blister rust and fire exclusion are widely recognized threats, long-term demographic data that document the effects of these stressors are rare.

Size-based matrix models indicate that most unburned populations have negative growth rates (λ range: 0.82–1.04). The growth rate of most populations was, however, indistinguishable from replacement levels (λ = 1.0), implying that, if populations are indeed declining, the progression of any such decline is slow, and longer observations are needed to clearly determine population trends. We found significant differences among population growth rates, primarily due to variation in recruitment rates. Deaths associated with blister rust and stress (i.e., resource competition) were common, suggesting significant roles for both blister rust and fire exclusion in determining population trajectories. Data from 15 prescribed fires showed that the immediate effect of burning was the death of many small trees, with the frequency of mortality returning to pre-fire levels within five years. In spite of a poor prognosis for sugar pine, our results suggest that we have time to apply and refine management strategies to protect this species.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/03-5109","usgsCitation":"van Mantgem, P.J., Stephenson, N.L., Keifer, M., and Keeley, J.E., 2004, Effects of an introduced pathogen and fire exclusion on the demography of sugar pine: Ecological Applications, v. 14, no. 5, p. 1590-1602, https://doi.org/10.1890/03-5109.","productDescription":"13 p.","startPage":"1590","endPage":"1602","numberOfPages":"13","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130692,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db699081","contributors":{"authors":[{"text":"van Mantgem, Phillip J. 0000-0002-3068-9422 pvanmantgem@usgs.gov","orcid":"https://orcid.org/0000-0002-3068-9422","contributorId":2838,"corporation":false,"usgs":true,"family":"van Mantgem","given":"Phillip","email":"pvanmantgem@usgs.gov","middleInitial":"J.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":317097,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stephenson, Nathan L. 0000-0003-0208-7229 nstephenson@usgs.gov","orcid":"https://orcid.org/0000-0003-0208-7229","contributorId":2836,"corporation":false,"usgs":true,"family":"Stephenson","given":"Nathan","email":"nstephenson@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":317094,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keifer, MaryBeth","contributorId":21841,"corporation":false,"usgs":true,"family":"Keifer","given":"MaryBeth","affiliations":[],"preferred":false,"id":317095,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":317096,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

It also hosts environmentally sensitive elements (ESE) such as Se, As, Hg, Ni, Cd, Zn, and Cr. Primary chemistry, elemental distribution patterns, and mineralogy within the Meade Peak were modified by element migration and possibly the introduction of elements. Fluids moved within the Meade Peak throughout its history, although the passage of fluids was highly variable in space and time, resulting in small domains of different rock chemistry and different mineralogy. Timing of major events affecting the Meade Peak and mineral habit are used to differentiate among detrital, diagenetic, epigenetic, and supergene mineral assemblages. Cross-cutting relationships among minerals are too rare to provide much paragenetic infor- mation. Carbonate fluorapatite (CFA) occurs in several forms, but dominantly as pelloids, some of which may have formed in situ during diagenesis. The other volumetrically signifi- cant form of CFA is interstitial cement that formed during diagenesis. Beginning during diagenesis and continuing intermittently, multiple generations of carbonate (dolomite and calcite) formed overgrowths and texturally complex carbonate cements. Movement and precipitation of silica followed a similar pattern. The ammonium feldspar buddingtonite, which generally rims orthoclase, also formed during diagenesis. Bacteria apparently played a significant role during diagenesis as well as during supergene processes, resulting in extreme fractionation of S isotopes and the possible bacterially mediated formation of minerals such as glauconite and sphalerite.</p><p id=\"simple-para.0015\">Catagenesis, apparently culminating in oil generation, was the last significant diagenetic change. Thrusting accompanied by fluid (oil and brine) migration began during catagenesis in the Late Jurassic or Cretaceous and continued into the early Eocene.</p><p id=\"simple-para.0020\">Fluorite ± carbonate ± barite± bitumen veins formed as a result of brittle deformation and accompanying fluid movement. This fracturing event may have been associated with a period of extension and normal faulting (Neogene to Holocene). Passage of the Yellowstone hot spot to the north of the area during the Neogene is marked by silicic domes and basaltic flows. The enrichment of Hg in fracture coatings might be the result of deposition from warm fluids associated with the emplacement of the silicic domes or a generally elevated, regional thermal gradient associated with the volcanism.</p><p id=\"simple-para.0025\">Many of the fracture systems are still open and continue to provide fluid pathways that are the primary depositional sites for a wide variety of supergene minerals (such as Se, efflorescent salts) and element associations (such as Hg, Cd-S, Fe-Cr-O) in which many of the ESE are concentrated. Native Se is the most commonly identified host of Se in the studied samples. The largest concentration of Se occurs in open-fracture systems that cross-cut waste rock and ore units. The age(s) of native Se formation is not known; how- ever, the latest period of Se mobility is the present. Direct measurement of efflorescent “salts” forming on new mine faces indicate that several ESE, including both Se and Zn, are concentrated on the faces soon after they are exposed. Zinc is present as hydrous sulfates, but the residence of Se in these “salts” is unknown.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Handbook of exploration and environmental geochemistry, Vol. 8","language":"English","publisher":"Elsevier","doi":"10.1016/S1874-2734(04)80010-X","usgsCitation":"Grauch, R.I., Desborough, G.A., Meeker, G.P., Foster, A., Tysdal, R.G., Herring, J.R., Lowers, H., Ball, B.A., Zielinski, R.A., and Johnson, E.A., 2004, Chapter 8 Petrogenesis and mineralogic residence of selected elements in the meade peak phosphatic shale member of the permian phosphoria formation, Southeast Idaho, chap. <i>of</i> Handbook of exploration and environmental geochemistry, Vol. 8, v. 8, p. 189-226, https://doi.org/10.1016/S1874-2734(04)80010-X.","productDescription":"38 p.","startPage":"189","endPage":"226","costCenters":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":353972,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.5,\n              42.5\n            ],\n            [\n              -111,\n              42.5\n            ],\n            [\n              -111,\n              43\n            ],\n            [\n              -111.5,\n              43\n            ],\n            [\n              -111.5,\n              42.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5aff0689e4b0da30c1bfcdb5","contributors":{"authors":[{"text":"Grauch, Richard I. 0000-0002-1763-0813 rgrauch@usgs.gov","orcid":"https://orcid.org/0000-0002-1763-0813","contributorId":1193,"corporation":false,"usgs":true,"family":"Grauch","given":"Richard","email":"rgrauch@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":734753,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Desborough, George A.","contributorId":101661,"corporation":false,"usgs":true,"family":"Desborough","given":"George","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":734754,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meeker, Gregory P.","contributorId":62974,"corporation":false,"usgs":true,"family":"Meeker","given":"Gregory","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":734755,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Foster, A.

Sea otter researchers are interested in foraging ecology for many different reasons, but for heuristic purposes we identify three general types of research questions: (1) questions about the implications of foraging decisions to individual fitness, the evolutionary significance of feeding strategies, and the selective forces and constraints that shape an individual’s diet and feeding behavior; (2) questions about the population- level implications of foraging ecology; for example, how is the status of a population (with respect to carrying capacity) reflected by the foraging success or diet composition of individuals within the population (Fig. 1); and (3) questions about the community-level consequences of sea otter foraging. Sea otters provide an excellent study system for all three types of questions because they are a tractable species to study (generally feeding near shore and bringing all prey to the surface to consume), they exhibit a wide range of diets and foraging strategies in different habitats and at different population densities, they tend to have strong trophic interactions with their prey species, and their foraging behavior can have profound effects on community structure in the nearshore marine community.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Alaska Sea Otter Research Workshop: Addressing the Decline of the Southwestern Alaska Sea Otter Population","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Alaska Sea Otter Research Workshop","conferenceDate":"5-7 April 2004","conferenceLocation":"Seward, AK","language":"English","publisher":"Alaska Sea Grant College Program, University of Alaska Fairbanks","publisherLocation":"Fairbanks, AK","doi":"10.4027/asorw.2004","isbn":"1-56612-088-8","usgsCitation":"Tinker, M.T., Estes, J.A., Bodkin, J.L., Staedler, M., and Monson, D., 2004, Studying sea otter foraging ecology: A review of some methodological approaches, <i>in</i> Alaska Sea Otter Research Workshop: Addressing the Decline of the Southwestern Alaska Sea Otter Population, Seward, AK, 5-7 April 2004, p. 54-59, https://doi.org/10.4027/asorw.2004.","productDescription":"6 p.","startPage":"54","endPage":"59","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":478147,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://repository.library.noaa.gov/view/noaa/40641","text":"External Repository"},{"id":339046,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58e35f81e4b09da67997ecb7","contributors":{"editors":[{"text":"Maldini, Daniela","contributorId":190288,"corporation":false,"usgs":false,"family":"Maldini","given":"Daniela","email":"","affiliations":[],"preferred":false,"id":688063,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Calkins, Donald","contributorId":190289,"corporation":false,"usgs":false,"family":"Calkins","given":"Donald","email":"","affiliations":[],"preferred":false,"id":688064,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Atkinson, Shannon","contributorId":190290,"corporation":false,"usgs":false,"family":"Atkinson","given":"Shannon","email":"","affiliations":[],"preferred":false,"id":688065,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Meehan, Rosa","contributorId":190291,"corporation":false,"usgs":false,"family":"Meehan","given":"Rosa","email":"","affiliations":[],"preferred":false,"id":688066,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Tinker, M.

The unique life history characteristics of bats prevent many people from realizing that they comprise 15 percent of our native mammal fauna.
