Instead, the carbon-isotopic and hydrocarbon-biomarker signatures of 61 tar ball samples, collected from shorelines throughout the northern and western parts of the sound, are all remarkably similar and have characteristics consistent with those of oil products that originated from the Monterey Formation source rocks of California. The carbon-isotopic compositions of the tar balls are all closely grouped (??13CPDB = -23.7 ?? 0.2???), within the range found in crude oils from those rocks, but are distinct from isotopic compositions of 28 samples of residues from the Exxon Valdez oil spill (??13CPDB = -29.4 ?? 0.1???). Likewise, values for selected biomarker ratios in the tar balls are all similar but distinct from values of residues from the 1989 oil spill. Carbon-isotopic and biomarker signatures generally relate the tar balls to oil products used in Alaska before ???1970 for construction and pavements. How these tar balls with such similar geochemical characteristics became so widely dispersed throughout the northern and western parts of the sound is not known with certainty, but the great 1964 Alaska earthquake was undoubtedly an important trigger, causing spills from ruptured storage facilities of California-sourced asphalt and fuel oil into Prince William Sound.","language":"English","publisher":"ACS","doi":"10.1021/es00010a033","issn":"0013936X","usgsCitation":"Kvenvolden, K., Hostettler, F., Carlson, P., Rapp, J.B., Threlkeld, C.N., and Warden, A., 1995, Ubiquitous tar balls with a California-source signature on the shorelines of Prince William Sound, Alaska: Environmental Science & Technology, v. 29, no. 10, p. 2684-2694, https://doi.org/10.1021/es00010a033.","productDescription":"11 p.","startPage":"2684","endPage":"2694","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":227007,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"10","noUsgsAuthors":false,"publicationDate":"2002-05-01","publicationStatus":"PW","scienceBaseUri":"505bbbf8e4b08c986b32893d","contributors":{"authors":[{"text":"Kvenvolden, K.A.","contributorId":80674,"corporation":false,"usgs":true,"family":"Kvenvolden","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":380658,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hostettler, F.

Comparison of petrographic, palynologic, and paleobotanic data from the same sample sets from the two cores allowed for comparison of compositional data within the Little Fire Creek coal bed. The proximate, petrographic, palynologic, and plant tissue data from two sets of samples indicate a high ash, gelocollinite- and liptinite-rich coal consisting of a relatively diverse paleoflora, including lycopsid trees, small lycopsids, tree ferns, small ferns, pteridosperms (seed ferns), and rare calamites and cordaites. The relatively very high ash yields (3–80 wt%), the relatively thin subunits (1–28 cm), and the large scale vertical variations in palynomorph floras suggest that the study area was at the edge of the paleopea-forming environment. As a result, most of the compositional correspondences are among those components indicative of degradation or

Selective extraction studies and studies of radionuclide sorption by and leaching from components of UMT showed alkaline earth sulfate and hydrous ferric oxides to be important hosts of radium-226 (<sup>226</sup>Ra) in UMT. Extrapolating from studies of barite dissolution in anerobic lake sediments, the leaching of <sup>226</sup>Ra from UMT by sulfate-reducing bacteria was investigated; a marked increase in <sup>226</sup>Ra release to aqueous solution as compared to sterile controls was demonstrated. A similar action of iron(III)-reducing bacteria was later shown. Ion exchangers such as clay minerals can also promote the dissolution of host-phase minerals and thereby influence the fate of radionuclides such as <sup>226</sup>Ra. Radon release studies examined particle size and ore composition as variables. Aggregation of UMT particles was shown to mask the higher emanating fraction of finer particles. Studies of various ores and ore components showed that UMT cannot be assumed to have the same radon-release characteristics as their precursor ores, nor can <sup>226</sup>Ra retained by various substrates be assumed to emanate the same fraction of radon. Over the last decade, USGS research directed at offsite mobility of radionuclides from uranium mining and milling processes has focused on six areas: the Midnite Mine in Washington; Ralston Creek and Reservoir, Colorado; sites near Canon City, Colorado; the Monument Valley District of Arizona and Utah; the Cameron District of Arizona; and the Puerco River basin of Arizona and New Mexico.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00776028","issn":"09430105","usgsCitation":"Landa, E.R., and Gray, J.R., 1995, US Geological Survey research on the environmental fate of uranium mining and milling wastes: Environmental Geology, v. 26, no. 1, p. 19-31, https://doi.org/10.1007/BF00776028.","productDescription":"13 p.","startPage":"19","endPage":"31","numberOfPages":"13","costCenters":[],"links":[{"id":205768,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00776028"},{"id":226666,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbb50e4b08c986b32861f","contributors":{"authors":[{"text":"Landa, E.

The U.S. Geological Survey and the University of Nebraska-Lincoln have collaborated on the development of a new approach to land-cover characterization that attempts to address requirements of the global-change research community and others interested in regional patterns of land cover. An experimental 1 -kilometer-resolution database of land-cover characteristics for the coterminous U.S. has been prepared to test and evaluate the approach. Using multidate Advanced Very High Resolution Radiometer (AVHRR) satellite data complemented by elevation, climate, ecoregions, and other digital spatial datasets, the authors define 152, seasonal land-cover regions. The regionalization is based on a taxonomy of areas with respect to data on land cover, seasonality or phenology, and relative levels of primary production. The resulting database consists of descriptions of the vegetation, land cover, and seasonal, spectral, and site characteristics for each region. These data are used in the construction of an illustrative 1:7,500,000-scaIe map of the seasonal land-cover regions as well as of smaller-scale maps portraying general land cover and seasonality. The seasonal land-cover characteristics database can also be tailored to provide a broad range of other landscape parameters useful in national and global-scale environmental modeling and assessment.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1111/j.1467-8306.1995.tb01798.x","usgsCitation":"Loveland, T.R., Merchant, J.W., Brown, J.F., Ohlen, D.O., Reed,

The central part of this major field in northeast Nevada and adjacent Utah is herein defined by 23<span>&nbsp;</span><sup>40</sup>Ar/<sup>39</sup>Ar ages that range from 42.6 to 39.0 Ma, rock chemistry from 12 localities, stratigraphic position of the volcanic rocks above a regional middle Eocene unconformity, volcanic setting, and lithology. The type area is at Nanny Creek, in the northern Pequop Mountains, Nevada, where rhyolite ash flow tuffs are overlain by a thick section of intercalated andesitic to dacitic flows and flow breccias and rhyolite ash flow tuffs. The intermediate composition rocks are locally derived throughout the volcanic field, whereas the sources for rhyolite ash flow tuffs are unknown. The uniform and widespread occurrence of the andesitic and dacitic flows and flow breccias strongly suggests that the upper crust was perforated by intermediate composition magma across the entire region. In the central part of the field the middle Eocene volcanic rocks rest with depositional angular discordance on deformed middle Paleozoic to Triassic strata; ostracode-bearing limestone, probably of early Eocene age, is locally present below the volcanic rocks. In the western and southeastern parts of the field these middle Eocene volcanic rocks rest with depositional angular discordance on lower Eocene lacustrine strata of the Elko and White Sage Formations, respectively. This angular discordance documents a middle Eocene deformational event previously unrecognized in the region.</p></div></div>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/94JB03389","issn":"01480227","usgsCitation":"Brooks, W.E., Thorman, C., and Snee, L., 1995, The 40Ar/39Ar ages and tectonic setting of the Middle Eocene northeast Nevada volcanic field: Journal of Geophysical Research, v. 100, no.

On average, 1.35 operators had to be contacted and 1.70 interviews were required to obtain a decision on access to a farm. On 77% of the farms, cooperators placed at least one restriction on access, most commonly requiring walking access only or notification before nighttime work. Cost of obtaining access averaged $265/farm in wages and travel expenses. No cooperators were willing to sign written access agreements. Operators rescinded access to four farms and drained three wetland basins during the first year; six of the seven sites lost were in the intensively cropped portion of a low-wetland-density zone. The difficulty of obtaining and retaining research access to privately owned wetland basins in intensively cropped areas may be related to landowner attitudes towards wetlands. Researchers may have to rely on remote sensing or consider payment for access to secure representative research sites in such areas. Unwillingness of cooperators to sign access agreements may jeopardize research by the newly formed National Biological Service and other resource management agencies.","language":"English","publisher":"Springer","doi":"10.1007/BF03160887","usgsCitation":"Fellows, D.P., and Buhl, T.K., 1995, Research access to privately owned wetland basins in the prairie pothole region of the United States: Wetlands, v. 15, no. 4, p. 330-335, https://doi.org/10.1007/BF03160887.","productDescription":"6 p.","startPage":"330","endPage":"335","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":133538,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a19e4b07f02db605644","contributors":{"authors":[{"text":"Fellows, David P.","contributorId":80607,"corporation":false,"usgs":true,"family":"Fellows","given":"David","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":310621,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Buhl, Thomas K. 0000-0001-9909-3419 tbuhl@usgs.gov","orcid":"https://orcid.org/0000-0001-9909-3419","contributorId":3934,"corporation":false,"usgs":true,"family":"Buhl","given":"Thomas","email":"tbuhl@usgs.gov","middleInitial":"K.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":310622,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Well away from the fracture (farfield), the deformed granite has about twice the crack density (crack length per unit area) of undeformed granite. The microcrack density increases dramatically in a process zone that surrounds the fracture tip, and the fracture tip itself has more than an order of magnitude increase in crack density over the undeformed rock. Microcrack densities are consistently higher on the dilational side of the shear than on the compressional side. Microcracks in the undeformed rock and in the far-field areas of the laboratory sample are concentrated within and along the margins of quartz crystals, but near the shear fracture they are somewhat more abundant within K-feldspar crystals. The energy release rate,<span>&nbsp;</span><i>g</i><sub><i>II</i></sub>, for mode II fracture progagation is estimated from the microcrack density data to be ≥ 1.7–8.6 kJ m<sup>−2</sup>. The microcracks that formed during the experiment are principally tensile cracks whose orientations reflect the local stress field: those formed prior to the nucleation of the fault are roughly parallel to the cylinder axis (loading direction), whereas those generated in the process zone make angles averaging 30 ° to the overall fault strike (and 20 ° to the cylinder axis). The preferred orientation and uneven distribution of microcracks in the process zone tends to pull the propagating fracture tip towards the dilational side, even though the trend is away from the overall fault strike. As a result, the propagating shear follows the microcrack trend for some distance and then changes direction in order to maintain an overall in-plane propagation path. This recurring process produces a zig-zag or sawtooth segmentation pattern similar to the sawtooth geometries of faults such as the San Andreas fault.</p></div></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0191-8141(94)E0018-T","issn":"01918141","usgsCitation":"Moore, D., and Lockner, D., 1995, The role of microcracking in shear-fracture propagation in granite: Journal of Structural Geology, v. 17, no. 1, p. 95-114, https://doi.org/10.1016/0191-8141(94)E0018-T.","productDescription":"20 p.","startPage":"95","endPage":"114","numberOfPages":"20","costCenters":[],"links":[{"id":227684,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baf84e4b08c986b32485d","contributors":{"authors":[{"text":"Moore, Diane E. 0000-0002-8641-1075","orcid":"https://orcid.org/0000-0002-8641-1075","contributorId":106496,"corporation":false,"usgs":true,"family":"Moore","given":"Diane E.","affiliations":[],"preferred":false,"id":383701,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lockner, D.A. 0000-0001-8630-6833","orcid":"https://orcid.org/0000-0001-8630-6833","contributorId":85603,"corporation":false,"usgs":true,"family":"Lockner","given":"D.A.","affiliations":[],"preferred":false,"id":383700,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Most wetland basins in the northern prairies hold water in some years and are dry in others. To assess the potential effect of climate change on the number of wetland basins holding water in a given year, one must first determine how much of the variability in number of wet basins is accounted for by climatic variables. I used multiple linear regression to examine the relationship between climate variables and percentage of wet basins throughout the Prairie Pothole Region of Canada and the United States. The region was divided into three areas: parkland, Canadian grassland, and United States grassland (i.e., North Dakota and South Dakota). The models - which included variables for spring and fall temperature, yearly precipitation, the previous year's count of wet basins, and for grassland areas, the previous fall precipitation - accounted for 63 to 65% of the variation in the number of wet basins. I then explored the sensitivities of the models to changes in temperature and precipitation, as might be associated with increased greenhouse gas concentrations. Parkland wetlands are shown to be much more vulnerable to increased temperatures than are wetlands in either Canadian or United States grasslands. Sensitivity to increased precipitation did not vary geographically. These results have implications for waterfowl and other wildlife populations that depend on availability of wetlands in the parklands for breeding or during periods of drought in the southern grasslands.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/BF01091840","usgsCitation":"Larson, D.L., 1995, Effects of climate on numbers of northern prairie wetlands: Climatic Change, v. 30, no. 2, p. 169-180, https://doi.org/10.1007/BF01091840.","productDescription":"12 p.","startPage":"169","endPage":"180","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":134337,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2fe4b07f02db616141","contributors":{"authors":[{"text":"Larson, Diane L. 0000-0001-5202-0634 dlarson@usgs.gov","orcid":"https://orcid.org/0000-0001-5202-0634","contributorId":2120,"corporation":false,"usgs":true,"family":"Larson","given":"Diane","email":"dlarson@usgs.gov","middleInitial":"L.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":310484,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Variations in physiographic controls on channel morphology result in systematic changes in vegetation patterns and geomorphic functions with increasing drainage basin area. In upstream reaches, streams have abundant bedrock control and bank heights that typically are less than or equal to the rooting depth of trees. In downstream reaches where valleys are wider and alluvial banks are higher vegetation has different geomorphic functions. At drainage areas of greater than 100–200 kM<sup>2</sup>, Ozarks streams are characterized by longitudinally juxtaposed reaches of high and low lateral channel migration rates, referred to as disturbance reaches and stable reaches, respectively. Whereas stable reaches can develop stable forested floodplains (if they are not farmed), disturbance reaches are characterized by dynamic vegetation communities that interact with erosion and deposition processes.</p><p>Disturbance reaches can be subdivided into low-gradient and high-gradient longitudinal zones. Low-energy zones are characterized by incremental, unidirectional lateral channel migration and deposition of gravel and sand bars. The bars are characterized by prominent bands of woody vegetation and ridge and swale topography. Channel monitoring data indicate that densely vegetated bands of woody vegetation formed depositional sites during bedload-transporting events. The same floods caused up to 20 m of erosion of adjacent cutbanks, scoured non-vegetated areas between vegetation bands, and increased thalweg depth and definition. In high-energy (or riffle) zones, channel movement is dominantly by avulsion. In these zones, vegetation creates areas of erosional resistance that become temporary islands as the channel avulses around or through them. Woody vegetation on islands creates steep, root-defended banks that contribute to narrow channels with high velocities.</p><p>Calculation of hydraulic roughness from density and average diameter of woody vegetation groups of different ages indicates that flow resistance provided by vegetation decreases systematically with group age, mainly through decreasing stem density. If all other factors remain constant, the stabilizing effect of a group of woody vegetation on a gravel bar decreases with vegetation age.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/0169-555X(95)00034-3","usgsCitation":"McKenney, R., Jacobson, R., and Wertheimer, R., 1995, Woody vegetation and channel morphogenesis in low-gradient, gravel-bed streams in the Ozarks Plateaus, Missouri and Arkansas: Geomorphology, v. 13, p. 175-198, https://doi.org/10.1016/0169-555X(95)00034-3.","productDescription":"23 p.","startPage":"175","endPage":"198","numberOfPages":"23","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":129077,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4ee6","contributors":{"authors":[{"text":"McKenney, R.","contributorId":27400,"corporation":false,"usgs":true,"family":"McKenney","given":"R.","email":"","affiliations":[],"preferred":false,"id":310516,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jacobson, R.

Our data demonstrate that the composition and abundance of the calanoid community after 1983 is not unlike that of 1960s and that species diversity of the calanoid community is more diverse than the cladoceran community in the 1990s as compared to the early 1980s. Even though the relative biomass of the cladocerans has remained similar over the 1983-1993 period, the species diversity and evenness of the Cladocera community in the early 1990s is unlike anything that has been previously reported for Lake Michigan. Cladocera dominance is centered in one species, <i>Daphnia</i> galeata mendotae, and only three species of Cladocera were observed in the pelagic region of the lake in 1991 and 1992. Nutrient levels, phytoplankton biomass, and the abundance of planktivorous alewife and bloater chub and <i>Bythotrephes</i> are examined as possible causes of these changes in zooplankton species composition. The increase in Rotifera biomass, but not Crustacea, was correlated with an increase in relative biomass of unicellular algae. Food web models suggest <i>Bythotrephes</i> will cause Lake Michigan's plankton to return to a community similar to that of the 1970s; that is <i>Diaptomus</i> dominated. Such a change has occurred. However, correlational analysis suggest that alewife and bloater chubs (especially juveniles) are affecting size and biomass of larger species of zooplankton as well as <i>Bythotrephes</i>.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0380-1330(95)71073-5","collaboration":"Out-of-print","usgsCitation":"Makarewicz, J.C., Bertram, P., Lewis, T., and Brown, E.H., 1995, A decade of predatory control of zooplankton species composition of Lake Michigan: Journal of Great Lakes Research, v. 21, no. 4, p. 620-640, https://doi.org/10.1016/S0380-1330(95)71073-5.","productDescription":"p. 620-640","startPage":"620","endPage":"640","numberOfPages":"20","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":266594,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0380-1330(95)71073-5"},{"id":133512,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b25e4b07f02db6af189","contributors":{"authors":[{"text":"Makarewicz, Joseph C.","contributorId":25120,"corporation":false,"usgs":true,"family":"Makarewicz","given":"Joseph","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":310155,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bertram, Paul","contributorId":34478,"corporation":false,"usgs":true,"family":"Bertram","given":"Paul","affiliations":[],"preferred":false,"id":310157,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lewis, Theodore","contributorId":107664,"corporation":false,"usgs":true,"family":"Lewis","given":"Theodore","email":"","affiliations":[],"preferred":false,"id":310158,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brown, Edward H.

Included are results for mechanical and electromagnetic water-current meters that are commonly used for stream gaging.

The present study quantitatively assesses the importance of the CRP by estimating changes in breeding-bird populations of North Dakota projected if CRP land would revert to cultivation. Of 18 species that were common in CRP or crop fields or both, 12 were more abundant in CRP habitats. Six of these species had suffered significant population declines during 1967-1990, according to the North American Breeding Bird Survey. In contrast, none of the six species that were more common in cropland than in CRP fields had declined significantly. Termination of the Conservation Reserve Program and a return of enrolled land to cultivation is projected to cause population declines in North Dakota exceeding 17% for Sedge wren (Cistothorus platensis), Grasshopper sparrow (Ammodramus savannarum), Savannah Sparrow (Passerculus sandwichensis), Dickcissel (Spiza americana), and Lark Bunting (Calamospiza melanocorys).","language":"English","publisher":"Wilson Bulletin","usgsCitation":"Johnson, D.H., and Igl, L., 1995, Contributions of the Conservation Reserve Program to populations of breeding birds in North Dakota: The Wilson Bulletin, v. 107, no. 4, p. 709-718.","productDescription":"10 p.","startPage":"709","endPage":"718","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":128758,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":10999,"rank":200,"type":{"id":15,"text":"Index Page"},"url":"https://sora.unm.edu/node/131336"}],"volume":"107","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4af2e4b07f02db691889","contributors":{"authors":[{"text":"Johnson, Douglas H. 0000-0002-7778-6641","orcid":"https://orcid.org/0000-0002-7778-6641","contributorId":70327,"corporation":false,"usgs":true,"family":"Johnson","given":"Douglas","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":310624,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Igl, L.D. 0000-0003-0530-7266","orcid":"https://orcid.org/0000-0003-0530-7266","contributorId":13568,"corporation":false,"usgs":true,"family":"Igl","given":"L.D.","affiliations":[],"preferred":false,"id":310623,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Cost effectiveness of such efforts is questioned. The prairie pothole region (PPR) is the primary breeding ground of several species of North American ducks (Bellrose 1980). Much habitat of breeding ducks in the PPR has been destroyed or degraded by intensive agriculture (e.g., Kiel et al. 1972, Bellrose 1980, Sugden and Beyersbergen 1984, Boyd 1985), resulting in high predation rates on duck nests (Sargeant and Raveling 1992). Because of predation, hatch rate (HR) of duck nests in Waterfowl Production Areas (WPA's) in the PPR is often less than the 15-20% suggested for stability of populations of the 5 most common species of dabbling ducks (e.g., Cowardin et al. 1985, Greenwood 1986, Klett et al. 1988, Greenwood et al. 1990). Managers seek ways to reduce depredations of duck clutches in WPA's, but little information is available concerning effects of predator removal. We evaluated seasonal (spring and early summer) removal of predators from WPA's in Minnesota and North Dakota. Our objectives were to compare HR in uplands of WPA's with and without predators removed and to determine functional aspects of conducting predator removal.","language":"English","publisher":"Wildlife Society","usgsCitation":"Sargeant, A., Sovada, M., and Shaffer, T., 1995, Seasonal predator removal relative to hatch rate of duck nests in waterfowl production areas: Wildlife Society Bulletin, v. 23, no. 3, p. 507-513.","productDescription":"7 p.","startPage":"507","endPage":"513","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":133799,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc314","contributors":{"authors":[{"text":"Sargeant, A.B.","contributorId":13171,"corporation":false,"usgs":true,"family":"Sargeant","given":"A.B.","email":"","affiliations":[],"preferred":false,"id":310665,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sovada, M.A.","contributorId":54534,"corporation":false,"usgs":true,"family":"Sovada","given":"M.A.","affiliations":[],"preferred":false,"id":310666,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shaffer, T.L.","contributorId":98245,"corporation":false,"usgs":true,"family":"Shaffer","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":310667,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
