However, we were unable to detect an increase in principal component scores from mid-June though mid-September over two years of study.  Discriminant models that were developed to distinguish birds breeding in Canada from those breeding in the USA were poor predictors of the migratory status of Yellow-headed Blackbirds.

Species and individual variation in sensitivity to Pb poisoning among animals may be due to differential resistance to oxidative stress. The effects of oxidative stress caused by Pb exposure (1.7, 414, and 828 µg/g of diet) were compared for the first 6 wk in growing young of two species of waterfowl, Canada geese ( Branta canadensis ) and mallards ( Anas platyrhynchos ), with the first species being possibly more sensitive to Pb poisoning based on previous field and laboratory observations. Blood and liver Pb concentrations increased more in mallards than in geese. This may be explained on the basis of body weight, being 3.2 times higher in geese, and by hepatic metabolism, where GSH S -transferase (GST) activity is 2.9-fold higher in geese and presumably has a role in the binding of Pb to GSH and subsequent biliary excretion. In contrast, mallards showed higher hepatic levels of GSH and activities of GSH peroxidase (GPX) and GSH reductase (GR). Although both species showed a rise in hepatic GSH concentration with Pb exposure, the relationship between increased lipid peroxidation and Pb exposure was only significant in geese. Within treatment groups, hepatic GSH concentrations were inversely related to liver Pb concentrations in both species, which may correspond to the role of GSH in Pb excretion. Hepatic GSH was also inversely related to hepatic lipid peroxidation, but only in mallards and in agreement with the species differences observed in GPX and GR activities. The lower resistance to lipid peroxidation of Canada geese may explain why geese can die in the field from Pb poisoning after ingesting fewer shot than found in the gizzards of mallards and with lower liver Pb concentrations than in mallards.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/15287390152627228","usgsCitation":"Mateo, R., and Hoffman, D.J., 2001, Differences in oxidative stress between young Canada geese and mallards exposed to lead-contaminated sediment: Journal of Toxicology and Environmental Health, Part A, v. 64, no. 7, p. 531-545, https://doi.org/10.1080/15287390152627228.","productDescription":"15 p.","startPage":"531","endPage":"545","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202240,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"64","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d73b","contributors":{"authors":[{"text":"Mateo, R.","contributorId":61374,"corporation":false,"usgs":true,"family":"Mateo","given":"R.","affiliations":[],"preferred":false,"id":340234,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoffman, D.

These studies considered various stages in the life cycle, including embryonic development, sexual maturation, adult reproductive function, and aging. A major focus of our research has been the role of neuroendocrine systems that appear to synchronize both endocrine and behavioral responses. These studies provide the basis for our more recent research on the impact of endocrine disrupting chemicals (EDCs) on reproductive function in the Japanese quail. These endocrine active chemicals include pesticides, herbicides, industrial products, and plant phytoestrogens. Many of these chemicals appear to mimic vertebrate steroids, often by interacting with steroid receptors. However, most EDCs have relatively weak biological activity compared to native steroid hormones. Therefore, it becomes important to understand the mode and mechanism of action of classes of these chemicals and sensitive stages in the life history of various species. Precocial birds, such as the Japanese quail, are likely to be sensitive to EDC effects during embryonic development, because sexual differentiation occurs during this period. Accordingly, adult quail may be less impacted by EDC exposure. Because there are a great many data available on normal development and reproductive function in this species, the Japanese quail provides an excellent model for examining the effects of EDCs. Thus, we have begun studies using a Japanese quail model system to study the effects of EDCs on reproductive endocrine and behavioral responses. In this review, we have two goals: first, to provide a summary of reproductive development and sexual differentiation in intact Japanese quail embryos, including ontogenetic patterns in steroid hormones in the embryonic and maturing quail. Second, we discuss some recent data from experiments in our laboratory in which EDCs have been tested in Japanese quail. The Japanese quail provides an excellent avian model for testing EDCs because this species has well-characterized reproductive endocrine and behavioral responses. Considerable research has been conducted in quail in which the effects of embryonic steroid exposure have been studied relative to reproductive behavior. Moreover, developmental processes have been studied extensively and include investigations of the reproductive axis, thyroid system, and stress and immune responses. We have conducted a number of studies, which have considered long-term neuroendocrine consequences as well as behavioral responses to steroids. Some of these studies have specifically tested the effects of embryonic steroid exposure on later reproductive function in a multigenerational context. A multigenerational exposure provides a basis for understanding potential exposure scenarios in the field. In addition, potential routes of exposure to EDCs for avian species are being considered, as well as differential effects due to stage of the life cycle at exposure to an EDC. The studies in our laboratory have used both diet and egg injection as modes of exposure for Japanese quail. In this way, birds were exposed to a specific dose of an EDC at a selected stage in development by injection. Alternatively, dietary exposure appears to be a primary route of exposure; therefore experimental exposure through the diet mimics potential field situations. Thus, experiments should consider a number of aspects of exposure when attempting to replicate field exposures to EDCs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hormones and Behavior","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1006/hbeh.2001.1695","collaboration":"6251_Ottinger.pdf","usgsCitation":"Ottinger, M.A., Abdelnabi, M., Henry, P., McGary, S., Thompson, N., and Wu, J., 2001, Neuroendocrine and behavioral implications of endocrine disrupting chemicals in quail: Hormones and Behavior, v. 40, no. 2, p. 234-247, https://doi.org/10.1006/hbeh.2001.1695.","productDescription":"234-247","startPage":"234","endPage":"247","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202077,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17458,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1006/hbeh.2001.1695","linkFileType":{"id":5,"text":"html"}}],"volume":"40","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b01e4b07f02db6985bc","contributors":{"authors":[{"text":"Ottinger, M.

At each pond, aquatic vegetation and environmental variables (slope, water depth, sediment bulk density, sediment grain size, sediment organic content and porewater inorganic nutrients) were measured along five transects extending perpendicular to the shoreline from the upland border into the pond. Based on a variety of multivariate methods, including Detrended Correspondence Analysis (DCA), an indirect gradient analysis technique, and Canonical Correspondence Analysis (CCA), a direct gradient approach, it was determined that the eutrophic Herring Pond was dominated by floating aquatic vegetation (Brasenia schreberi, Nymphoides cordata, Nymphaea odorata), and the algal stonewort, Nitella. Partial CCA suggested that high porewater PO4-P concentrations and fine-grained sediments strongly influenced the vegetation of this eutrophic pond. In contrast, vegetation of the oligotrophic Duck Pond was sparse, contained no floating aquatics, and was dominated by emergent plants. Low porewater nutrients, low sediment organic content, high water clarity and low pH (4.8) best defined the environmental characteristics of this oligotrophic pond. Gull Pond, with inorganic nitrogen-enriched sediments, also exhibited a flora quite different from the oligotrophic Duck Pond. The species composition and relative abundance of aquatic macrophytes provide good indicators of the trophic status of freshwater ponds and should be incorporated into long-term monitoring programs aimed at detecting responses to anthropogenically-derived nutrient loading.","language":"English","publisher":"Springer","doi":"10.1023/A:1017540002675","usgsCitation":"Roman, C.T., Barrett, N.E., and Portnoy, J.W., 2001, Aquatic vegetation and trophic condition of Cape Cod (Massachusetts, USA) kettle ponds: Hydrobiologia, v. 443, no. 1-3, p. 31-42, https://doi.org/10.1023/A:1017540002675.","productDescription":"12 p.","startPage":"31","endPage":"42","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":487592,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.uri.edu/nrs_facpubs/735","text":"External Repository"},{"id":201542,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Massachusetts","otherGeospatial":"Cape Cod, Duck Pond, Great Pond, Gull Pond, Herring Pond, Ryder Pond","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.00293016433716,\n              41.9307622765775\n            ],\n            [\n              -69.99853134155273,\n              41.9307622765775\n            ],\n            [\n              -69.99853134155273,\n              41.934944575654136\n            ],\n            [\n              -70.00293016433716,\n              41.934944575654136\n            ],\n            [\n              -70.00293016433716,\n              41.9307622765775\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.01518249511717,\n              41.95297959371308\n            ],\n            [\n              -70.00170707702637,\n              41.95297959371308\n            ],\n            [\n              -70.00170707702637,\n              41.95949009892467\n            ],\n            [\n              -70.01518249511717,\n              41.95949009892467\n            ],\n            [\n              -70.01518249511717,\n              41.95297959371308\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.01745700836182,\n              41.96153247330561\n            ],\n            [\n              -70.01063346862793,\n              41.96153247330561\n            ],\n            [\n              -70.01063346862793,\n              41.96469164222695\n            ],\n            [\n              -70.01745700836182,\n              41.96469164222695\n            ],\n            [\n              -70.01745700836182,\n              41.96153247330561\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.03342151641846,\n              41.972987703611786\n            ],\n            [\n              -70.02711296081543,\n              41.972987703611786\n            ],\n            [\n              -70.02711296081543,\n              41.97652915457959\n            ],\n            [\n              -70.03342151641846,\n              41.97652915457959\n            ],\n            [\n              -70.03342151641846,\n              41.972987703611786\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.03423690795897,\n              41.964500181902785\n            ],\n            [\n              -70.02831459045409,\n              41.964500181902785\n            ],\n            [\n              -70.02831459045409,\n              41.96960559364801\n            ],\n            [\n              -70.03423690795897,\n              41.96960559364801\n            ],\n            [\n              -70.03423690795897,\n              41.964500181902785\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"443","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac5e4b07f02db67a00f","contributors":{"authors":[{"text":"Roman, C.

In fall, it traveled southwest towards India as expected, but stopped in southeastern Tibet and wintered in a restricted zone within the breeding range of the steppe eagle.  In spring, the bird returned to the same area of Mongolia where it was captured.  These observations, though derived from the movements of a single bird, suggest three things that are contrary to what is generally believed about steppe eagle biology.  First, not all steppe eagles move to warmer climes in winter.  Second, not all steppe eagles are nomadic in winter.  Finally, because our bird wintered at the periphery of the steppe eagle breeding range in Tibet, perhaps birds that breed in this same area also winter there.  If so, not all steppe eagles are migratory.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the Bombay Natural History Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Ellis, D.H., Moon, S., and Robinson, J.W., 2001, Annual movements of a steppe eagle (Aquila nipalensis) summering in Mongolia and wintering in Tibet: Journal of the Bombay Natural History Society, v. 98, no. 3, p. 335-340.","productDescription":"335-340","startPage":"335","endPage":"340","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202149,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"98","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad1e4b07f02db680d8f","contributors":{"authors":[{"text":"Ellis, D.

Other habitats found in the state vary from barrier beaches to dry coniferous woods on the coastal plain and mesophytic communities along the Piedmont in the north, allowing a diverse avifauna to prosper within a small geographic area.

These specific habitat requirements restrict the Kirtland's Warbler breeding range to only 13-16 counties in the northern lower peninsula of Michigan. Although the nature of the species' affinity for this habitat is poorly understood, one theory suggests that higher prey abundance in young jack pine may play a role. To explore further the hypothesis that Kirtland's Warblers choose nesting habitat due to prey abundance, a more thorough knowledge of the warblers' diet is needed. To better understand the diet, we identified arthropod and plant fragments found in 202 Kirtland's Warbler fecal samples, collected from June to September, 1995-1997. The major food items recorded were spittlebugs and aphids (Homoptera; found in 61% of all samples), ants and wasps (Hymenoptera; 45%), blueberry (Vaccinium augustifolium; 42%), beetles (Coleoptera; 25%), and moth larvae (Lepidoptera; 22%).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"5904 Deloria-Sheffield.pdf","usgsCitation":"Deloria-Sheffield, C.M., Millenbah, K.F., Bocetti, C.I., Sykes, P., and Kepler, C.B., 2001, Kirtland's warbler diet as determined through fecal analysis: The Wilson Bulletin, v. 113, no. 4, p. 384-387.","productDescription":"384-387","startPage":"384","endPage":"387","numberOfPages":"4","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":17450,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.bioone.org/perlserv/?request=get-abstract&doi=10.1676%2F0043-5643%282001%29113%5B0384%3AKSWDAD%5D2.0.CO%3B2","linkFileType":{"id":5,"text":"html"}},{"id":200278,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"113","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b47b5","contributors":{"authors":[{"text":"Deloria-Sheffield, Christie M.","contributorId":84875,"corporation":false,"usgs":true,"family":"Deloria-Sheffield","given":"Christie","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":340701,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Millenbah, Kelly F.","contributorId":49904,"corporation":false,"usgs":true,"family":"Millenbah","given":"Kelly","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":340698,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bocetti, Carol I.","contributorId":60343,"corporation":false,"usgs":true,"family":"Bocetti","given":"Carol","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":340699,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sykes, P.W.

Hydrologic manipulation of salt marshes affects marsh biogeochemistry and vegetation patterns, but responses by fishes and decapod crustaceans (nekton) remain unclear, This study examines nekton habitat-use patterns in the tide-restricted Hatches Harbor salt marsh (Provincetown, Massachusetts) relative to a downstream, unrestricted marsh. Nekton assemblages were sampled in tidal creek, marsh pool, and salt marsh surface habitats. Pools and creeks were sampled every two weeks for one year to account for seasonal variability, and the marsh surface was sampled at two-week intervals in summer and fall. Density, richness, and community composition of nekton in creek and marsh surface habitats were similar between the unrestricted and restricted marsh, but use of pools differed drastically on the two sides of the tide-restricting dike. In 95% of the cases tested, restricted marsh habitats provided equal or greater habitat value for nekton than the same habitat in the unrestricted marsh (based on density), suggesting that the restricted marsh did not provide a degraded habitat for most species. For some species, the restricted marsh provided nursery, breeding, and overwintering habitat during different seasons, and tidal restoration of this salt marsh must be approached with care to prevent losses of these valuable marsh functions.

Because soil organic matter plays a role in cycling nutrients, aerating soil, retaining water, and maintaining tilth, a significant reduction in organic matter content in a soil profile is not just evidence of a change in ecosystem function, but of damage to that soil ecosystem.  Reference sites were selected for comparison to contaminated sites, and additional sites were selected to illustrate how variables other than environmental contaminants might affect the Soil organic matter profile.  The survey was undertaken on the supposition that environmental contaminants and other stressors reduce the activity of earthworms and other macrofauna, inhibiting the incorporation of organic matter into the soil profile.  The profiles of the unstressed soils showed a continuous decrease in organic matter content from the uppermost mineral soil layer (0-2.5 cm) down to 15 cm.  Stressed soils showed an abrupt decrease in soil organic matter content below a depth of 2.5 cm.  The 2.5-5.0 cm layer of stressed soils--such as found in a pine barren, an orchard, sites contaminated with zinc, and a site with compacted soil--had less than 4% total organic matter and less than 1% particulate organic matter.  However, damaged soil ecosystems were best identified by comparison of their profiles to the profiles of closely matched reference soils, rather than by comparison to these absolute values.  The presence or absence of earthworms offered a partial explanation of observed differences in soil organic matter profiles.","language":"English","publisher":"Springer","doi":"10.1023/A:1016707200900","usgsCitation":"Beyer, W., 2001, Estimating toxic damage to soil ecosystems from soil organic matter profiles: Ecotoxicology, v. 10, no. 5, p. 273-283, https://doi.org/10.1023/A:1016707200900.","productDescription":"11 p.","startPage":"273","endPage":"283","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201796,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a04e4b07f02db5f8620","contributors":{"authors":[{"text":"Beyer, W.

Pollock's robust design, involving multiple sampling occasions per period of interest, provides several advantages over classical approaches. This includes the ability to estimate the probability of being present and available for detection, which in some situations is equivalent to breeding probability. We present a model for estimating availability for detection that relaxes two assumptions required in previous approaches. The first is that the sampled population is closed to additions and deletions across samples within a period of interest. The second is that each member of the population has the same probability of being available for detection in a given period.

Eggs of three-egg clutches were collected from a PCB-exposed common tern (<i>Sterna hirundo</i>) colony (Ram Island, Buzzards Bay, MA, USA) and from a relatively clean colony (Bodkin Island, Chesapeake Bay, MD, USA), and were analyzed for concentrations of organochlorine contaminants and steroid hormones (17β-estradiol, 5α-dihydrotestosterone, testosterone and androstenedione). There was no relationship between total PCBs and steroid concentrations considering all eggs together, considering eggs of different laying order or considering differences between sequentially laid eggs in a clutch. Similarly, concentrations of di- and tri-chlorinated biphenyls and steroids in eggs were not related. The concentrations of PCBs, mercury and selenium were below estimated thresholds for toxicity to embryos. Maternal steroids, except estradiol, were present in yolk of all eggs, with increasing concentrations in the second and third eggs laid.

They provide safe access to non-roaded areas, support recreational opportunities such as hiking, biking, and wildlife observation, and protect natural resources by concentrating visitor traffic on resistant treads. However, increasing recreational use, coupled with poorly designed and/or maintained trails, has led to a variety of resource impacts. Trail managers require objective information on trails and their conditions to monitor trends, direct trail maintenance efforts, and evaluate the need for visitor management and resource protection actions.  This paper reviews trail impacts and different types of trail assessments, including inventory, maintenance, and condition assessment approaches.  Two assessment methods, point sampling and problem assessment, are compared empirically from separate assessments of a 15-mile segment of the Appalachian Trail in Great Smoky Mountains National Park.  Results indicate that point sampling and problem assessment methods yield distinctly different types of quantitative information.  The point sampling method provides more accurate and precise measures of trail characteristics that are continuous or frequent (e.g., tread width or exposed soil).  The problem assessment method is a preferred approach for monitoring trail characteristics that can be easily predefined or are infrequent (e.g., excessive width or secondary treads), particularly when information on the location of specific trail impact problems is needed.  The advantages and limitations of these two assessment methods are examined in relation to various management and research information needs.  The choice and utility of these assessment methods are also discussed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Park and Recreation Administration","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"5844_Marion.pdf","usgsCitation":"Marion, J., and Leung, Y., 2001, Trail resource impacts and an examination of alternative assessment techniques: Journal of Park and Recreation Administration, v. 19, no. 3, p. 17-37.","productDescription":"17-37","startPage":"17","endPage":"37","numberOfPages":"21","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201861,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269475,"type":{"id":11,"text":"Document"},"url":"https://js.sagamorepub.com/jpra/article/view/1565"}],"volume":"19","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4de4b07f02db626f20","contributors":{"authors":[{"text":"Marion, J.
