We assessed chromosome damage by micronucleus and flow cytometric assays and genetic variation by randomly amplified polymorphic DNA (RAPD) and mitochondrial DNA (mtDNA) analyses. The RAPD analysis showed no population structure, but mtDNA exhibited differentiation among and within populations. Genotoxicity effects were not observed when all individuals were analyzed. However, individuals with mtDNA haplotypes unique to the contaminated sites had greater chromosomal damage than contaminated-site individuals with haplotypes shared with reference sites. When interpopulation comparisons used individuals with unique haplotypes, one contaminated site had greater levels of chromosome damage than one or both of the reference sites. We hypothesize that shared-haplotype individuals are potential migrants and that unique-haplotype individuals are potential long-term residents. A parsimony approach was used to estimate the minimum number of migration events necessary to explain the haplotype distributions on a phylogenetic tree. The observed predominance of migration events into the contaminated sites supported our migration hypothesis. We conclude the atomic blast sites are ecological sinks and that immigration masks the genotoxic effects of radiation on the resident populations.","language":"English","publisher":"Society of Environmental Toxicology and Chemistry","publisherLocation":"Pensacola, FL","doi":"10.1002/etc.5620200212","usgsCitation":"Theodorakis, C.W., Bickham, J.W., Lamb, T., Medica, P.A., and Lyne, T.B., 2001, Integration of genotoxicity and population genetic analyses in kangaroo rats (<i>Dipodomys merriami</i>) exposed to radionuclide contamination at the Nevada Test Site, USA: Environmental Toxicology and Chemistry, v. 20, no. 2, p. 317-326, https://doi.org/10.1002/etc.5620200212.","productDescription":"10 p.","startPage":"317","endPage":"326","numberOfPages":"10","temporalStart":"1991-04-01","temporalEnd":"1991-05-26","costCenters":[{"id":135,"text":"Biological Resources Division","active":false,"usgs":true},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130996,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Department Of Energy Nevada Test Site","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120,35 ], [ -120,42 ], [ -114,42 ], [ -114,35 ], [ -120,35 ] ] ] } } ] }","volume":"20","issue":"2","noUsgsAuthors":false,"publicationDate":"2001-02-01","publicationStatus":"PW","scienceBaseUri":"4f4e49b4e4b07f02db5cac8b","contributors":{"authors":[{"text":"Theodorakis, Christopher W.","contributorId":87495,"corporation":false,"usgs":true,"family":"Theodorakis","given":"Christopher","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":317026,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bickham, John W.","contributorId":56184,"corporation":false,"usgs":true,"family":"Bickham","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":317024,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lamb, Trip","contributorId":15146,"corporation":false,"usgs":true,"family":"Lamb","given":"Trip","email":"","affiliations":[],"preferred":false,"id":317022,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Medica, Philip A.","contributorId":55780,"corporation":false,"usgs":true,"family":"Medica","given":"Philip","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":317023,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lyne, T.

Treatment of stream crossings involved excavating culverts and associated road fill and reshaping streambanks. A variety of techniques were applied to road benches, which included decompacting the road surface, placing unstable road fill in more stable locations, and re-establishing natural surface drainage patterns. Following treatment and a 12-year recurrence-interval storm, some road reaches and excavated stream crossings showed evidence of mass movement failures, gullying, bank erosion and channel incision. Post-treatment erosion from excavated stream crossings was related to two variables: a surrogate for stream power (drainage area × channel gradient) and the volume of fill excavated from the channel. Post-treatment erosion on road reaches was related to four explanatory variables: method of treatment, hillslope position (upper, mid-slope or lower), date of treatment, and an interaction term (hillslope position × method of treatment). Sediment delivery from treated roads in upper, middle and lower hillslope positions was 10, 135 and 550 m</span><sup>3</sup><span> of sediment per kilometre of treated roads, respectively. In contrast, inventories of almost 500 km of forest roads in adjacent catchments indicate that untreated roads produced 1500 to 4700 m</span><sup>3</sup><span> of sediment per kilometre of road length. Erosion from 300 km of treated roads contributed less than 2 per cent of the total sediment load of Redwood Creek during the period 1978 to 1998.

A conceptual model of channel organization delineates trajectories of response to sediment pulses for many types of gravel bed channels. Channels exhibited self‐organizing behavior to various degrees based on channel gradient, presence of large in‐channel wood or other forcing elements, the size of the sediment pulse, and the number of bed‐mobilizing flows since disturbance. Typical channel changes following a sediment pulse were initial decreases in water depth, in variability of bed elevations, and in the regularity of bed form spacing. Trajectories of change subsequently showed increased average water depth, more variable and complex bed topography, and increased uniformity of bed form spacing. Bed form spacing in streams with abundant forcing elements developed at a shorter spatial scale (two to five channel widths) than in streams without such forcing mechanisms (five to 10 channel widths).

Five uninfected control amakihi exposed at the same time to infective mosquito bites developed acute infections with high parasitemias.

When surviving birds were rechallenged &gt;2 yr later with either the same parasite isolate or an isolate of </span><i>P. relictum</i><span> collected on the island of Kauai, all individuals were immune to superinfection. Chronically infected birds developed antibodies to a common suite of malarial antigens ranging in size from 22 to 170 kDa that were detectable as early as 8 days post infection on immunoblots of SDS-polyacrylamide gels. Antibodies to this suite of malarial antigens persisted as long as 1,248 days after initial infection and were consistently detectable at times when parasites were not easily found by microscopy on Giemsa-stained blood smears. The immunoblotting method that is described here appears to be an effective technique for identifying birds with chronic, low-intensity malarial infections when circulating parasites are not easily detectable by microscopy. Hawaiian honeycreepers that are capable of recovering from acute infections develop concomitant immunity to superinfection, making them functionally immune in areas where malaria transmission has become endemic.</span></p>","language":"English","publisher":"Wildlife Disease Association","publisherLocation":"Lawrence, KS","doi":"10.7589/0090-3558-37.1.20","usgsCitation":"Atkinson, C.T., Dusek, R., and Lease, J.K., 2001, Serological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii Amakihi: Journal of Wildlife Diseases, v. 37, no. 1, p. 20-27, https://doi.org/10.7589/0090-3558-37.1.20.","productDescription":"8 p.","startPage":"20","endPage":"27","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":478844,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://www.bioone.org/doi/10.7589/0090-3558-37.1.20","text":"External Repository"},{"id":330925,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"37","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58259565e4b01fad86db2435","contributors":{"authors":[{"text":"Atkinson, Carter T. 0000-0002-4232-5335 catkinson@usgs.gov","orcid":"https://orcid.org/0000-0002-4232-5335","contributorId":1124,"corporation":false,"usgs":true,"family":"Atkinson","given":"Carter","email":"catkinson@usgs.gov","middleInitial":"T.","affiliations":[{"id":5049,"text":"Pacific Islands Ecosys Research Center","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":653504,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dusek, Robert J. 0000-0001-6177-7479 rdusek@usgs.gov","orcid":"https://orcid.org/0000-0001-6177-7479","contributorId":2397,"corporation":false,"usgs":true,"family":"Dusek","given":"Robert J.","email":"rdusek@usgs.gov","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":false,"id":653505,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lease, Julie K.","contributorId":176796,"corporation":false,"usgs":false,"family":"Lease","given":"Julie","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":653506,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Most shorebird use occurs in thesouthern reach of the estuary (South Bay). Thereduced water circulation and discharge fromindustrial sources in the South Bay are responsiblefor the highest levels of some trace elements in theestuary. Wintering shorebirds have been found to havestrong site fidelity to areas as small as a fewkilometers in the South Bay, which may increase theirexposure to contaminants near local point sources. Inaddition, different shorebird species foraging at thesame site have been shown to have differentcontaminant burdens. Thus, our objectives were totest whether contaminant burdens differed by species,or whether contaminant burdens differed in shorebirdscollected at adjacent sites. We examined thecontaminant profiles of two species of shorebirds,long-billed dowitchers (</span><i class=\"EmphasisTypeItalic \">Limnodromus scolopaceus</i><span>)and western sandpipers (</span><i class=\"EmphasisTypeItalic \">Calidris mauri</i><span>) thatforage together at two sites, Hayward and Newark,separated by 8 km in the South Bay. We usedmultivariate analysis of variance tests to compare thecomposition of 14 elemental analytes in their livertissues and estimated their molar ratios of Hg and Se. Composite samples were used for contaminant analysesbecause of the small body size of the shorebirds. Seven elemental analytes (Ag, Ba, Be, Cr, Ni, Pb, V)were below detection limits in a majority of thesamples so statistical analyses were precluded. Inthe measurable analytes (As, Cd, Cu, Hg, Mn, Se, Zn),we found no significant intra-site differences ofcontaminant profiles for the two species. We pooledthe samples to examine inter-site differences andfound significant differences in contaminant profilesbetween shorebirds at the neighboring sites (</span><i class=\"EmphasisTypeItalic \">P</i><span> = 0.03). Shorebirds at Newark had higher (</span><i class=\"EmphasisTypeItalic \">P</i><span> &lt; 0.05) concentrations of As, Cd, and Se than those at Hayward. Dowitchers at Newark had concentrations of Hg and Se which were highly correlated (</span><i class=\"EmphasisTypeItalic \">P</i><span> &lt; 0.003) in a mean molar ratio of 1:19, similar tothat reported in other birds. In the larger dowitcherspecies, we also examined exposure to 20organochlorine compounds. Organic analyses showedthat the dowitchers had been exposed to DDE, PCBs,dieldrin and trans-nonachlor, but with no significantdifferences in concentrations between Hayward andNewark (</span><i class=\"EmphasisTypeItalic \">P</i><span> &gt; 0.05).</span></p>","language":"English","publisher":"Springer","doi":"10.1023/A:1017526130205","usgsCitation":"Hui, C.A., Takekawa, J.Y., and Warnock, S.E., 2001, Contaminant profiles of two species of shorebirds foraging together at two neighboring sites in south San Francisco Bay, California: Environmental Monitoring and Assessment, v. 71, no. 2, p. 107-121, https://doi.org/10.1023/A:1017526130205.","productDescription":"15 p.","startPage":"107","endPage":"121","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":132542,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"71","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b12e4b07f02db6a279b","contributors":{"authors":[{"text":"Hui, Clifford A.","contributorId":68252,"corporation":false,"usgs":true,"family":"Hui","given":"Clifford","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":317321,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":317319,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Warnock, Sarah E.","contributorId":174903,"corporation":false,"usgs":false,"family":"Warnock","given":"Sarah","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":317320,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A steady-state model was developed to simulate bioaccumulation in aquatic biota and assess ecological and human health risks.  Trophic levels included phytoplankton, invertebrates, brown trout, and common carp.  Uptake routes included water, food, or sediment.  Based on an extensive review of the literature, distributions were derived for most inputs for use in Monte Carlo simulations.  Three scenarios represented ranges of dilution and turbidity.  Compared with the limited field data available, median estimates of Ag in carp (0.07-2.1 I&mu;g/g dry weight) were 0.5 to 9 times measured values, and all measurements were within the predicted interquartile range.  Median Ag concentrations in biota were ranked invertebrates > phytoplankton > trout > carp.  Biotic concentrations were highest for conditions of low dilution and low turbidity.  Critical variables included Ag assimilation eficiency, specific feeding rate, and the phytoplankton bioconcentration factor.  Bioaccumulation of Ag seems unlikely to result in txicity to aquatic biota and humans consuming fish.  Although the highest predicted Ag concentrations in water (>200 ng/L) may pose chronic risks to early survival and development of salmonids and risks of argyria to subsistence fishers, these results occur under highly conservative conditions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/etc.5620200226","collaboration":"Out-of-print","usgsCitation":"Warila, J., Batterman, S., and Passino-Reader, D.R., 2001, A probabilistic model for silver bioaccumulation in aquatic systems and assessment of human health risks: Environmental Toxicology and Chemistry, v. 20, no. 2, p. 432-441, https://doi.org/10.1002/etc.5620200226.","productDescription":"p. 432-441","startPage":"432","endPage":"441","numberOfPages":"9","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133637,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266635,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/etc.5620200226"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationDate":"2001-02-01","publicationStatus":"PW","scienceBaseUri":"4f4e4b1de4b07f02db6a990c","contributors":{"authors":[{"text":"Warila, James","contributorId":45270,"corporation":false,"usgs":true,"family":"Warila","given":"James","email":"","affiliations":[],"preferred":false,"id":310019,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Batterman, Stuart","contributorId":100806,"corporation":false,"usgs":true,"family":"Batterman","given":"Stuart","affiliations":[],"preferred":false,"id":310021,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Passino-Reader, Dora R.","contributorId":50839,"corporation":false,"usgs":true,"family":"Passino-Reader","given":"Dora","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":310020,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

However, few standard methods exist for quantifying soil stability in the field. A stability kit is described which can be inexpensively and easily assembled with minimal tools. It permits up to 18 samples to be evaluated in less than 10 min and eliminates the need for transportation, minimizing damage to soil structure. The kit consists of two 21×10.5×3.5 cm plastic boxes divided into eighteen 3.5×3.5 cm sections, eighteen 2.5-cm diameter sieves with 1.5-mm distance openings and a small spatula used for soil sampling. Soil samples are rated on a scale from one to six based on a combination of ocular observations of slaking during the first 5 min following immersion in distilled water, and the percent remaining on a 1.5-mm sieve after five dipping cycles at the end of the 5-min period. A laboratory comparison yielded a correlation between the stability class and percent aggregate stability based on oven dry weight remaining after treatment using a mechanical sieve. We have applied the method in a wide variety of agricultural and natural ecosystems throughout western North America, including northern Mexico, and have found that it is highly sensitive to differences in management and plant community composition. Although the field kit cannot replace the careful laboratory-based measurements of soil aggregate stability, it can clearly provide valuable information when these more intensive procedures are not possible.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0341-8162(00)00173-9","usgsCitation":"Herrick, J.E., Whitford, W.G., de Soyza, A.G., Van Zee, J.W., Havstad, K., Seybold, C.A., and Walton, M., 2001, Field soil aggregate stability kit for soil quality and rangeland health evaluations: Catena, v. 44, no. 1, p. 27-35, https://doi.org/10.1016/S0341-8162(00)00173-9.","productDescription":"9 p.","startPage":"27","endPage":"35","numberOfPages":"9","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":134060,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a06e4b07f02db5f8a2f","contributors":{"authors":[{"text":"Herrick, J.

Sightings increased in the Agassiz Lake Plain in the mid-1900's but remained rare west of the Agassiz Lake Plain until the late 1900's. Ornithologists suggest that the species has recently established small, permanent populations in the Turtle Mountains, Devils Lake area, and along the Sheyenne River, especially in the Sheyenne National Grassland.

The ecological significance of the region and impacts from intensive agriculture prompted the U.S. Environmental Protection Agency to select it as one of the first areas for developing and evaluating ecological indicators of wetland condition. We examined hypothesized relations between indicators of landscape and wetland conditions and waterfowl abundance on 45 40 km2 study sites in North Dakota for 1995-96. Landscape condition was defined a priori as the ratio of cropland area to total upland area surrounding wetlands. Measures of waterfowl abundance included estimated numbers of breeding pairs (by species and total numbers) and , a species-specific correction factor which effectively adjusts breeding pair estimates for annual or area-related differences in pond size. Landscape indicators and waterfowl measures varied among regions. Results indicated that most areas in the Coteau region are of much higher quality for ducks than those in the Drift Plain, and areas in the Red River Valley are of the poorest quality for ducks. Regression models demonstrated the impact of agricultural development on breeding duck populations in the Prairie Pothole Region. The most consistent landscape indicators of waterfowl abundance were percent of cropland and grassland. Models were inconsistent among years and species. The potential biotic indicators of landscape and wetland condition examined here would be appropriate for temporal trend analyses, but because of inherent geographic variability would not be appropriate for single-year geographic trend analyses without more extensive evaluations to improve explanatory models","language":"English","publisher":"Springer","doi":"10.1023/A:1010748527667","usgsCitation":"Austin, J.E., Buhl, T.K., Guntenspergen, G.R., Norling, W., and Sklebar, H.T., 2001, Duck populations as indicators of landscape condition in the Prairie Pothole Region: Environmental Monitoring and Assessment, v. 69, no. 1, p. 29-48, https://doi.org/10.1023/A:1010748527667.","productDescription":"20 p.","startPage":"29","endPage":"48","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true},{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":502407,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.unl.edu/usgsnpwrc/8","text":"External Repository"},{"id":133990,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a59e4b07f02db62ff66","contributors":{"authors":[{"text":"Austin, Jane E. jaustin@usgs.gov","contributorId":2839,"corporation":false,"usgs":true,"family":"Austin","given":"Jane","email":"jaustin@usgs.gov","middleInitial":"E.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":311919,"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":311922,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guntenspergen, Glenn R. 0000-0002-8593-0244 glenn_guntenspergen@usgs.gov","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":2885,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"Glenn","email":"glenn_guntenspergen@usgs.gov","middleInitial":"R.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":311923,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Norling, Wayne","contributorId":69877,"corporation":false,"usgs":true,"family":"Norling","given":"Wayne","email":"","affiliations":[],"preferred":false,"id":311921,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sklebar, H.
