The population is composed of aging adults with little natural recruitment. Factors contributing to the loss of early-life stages are unknown, but contaminants associated with fine sediments may play a role. The objectives of this study were to determine toxicities of sediments and pore waters from the Oconee River to early-life stages of robust redhorse and to establish toxic thresholds of metals (Cd, Cu, Mn, Zn) and ammonia, elements potentially threatening this species. Depositional sediments were collected from the only known spawning site and three sites downstream of major tributaries. Sediment pore waters were extracted in the laboratory from all sites and in situ at two sites. Toxicity tests with sediments, pore waters and metal solutions were initiated with eggs, yolk-sac fry and swim-up fry to determine effects on the life stage initially exposed as well as effects manifested in later developmental stages. Survival and growth were test endpoints, and toxicity was observed in both sediments and pore waters. Although the yolk- sac stage was the most sensitive across all tests, sediment toxicity was elicited only in tests initiated with eggs that developed through the yolk-sac stage. Toxicity appeared to be due to Mn in sediment and pore water exposures, but was more prevalent in pore waters. Sediment handling and the associated effects on redox potential contributed to the elevated concentrations of Mn in pore waters. Pore waters extracted in situ had significantly less Mn and were less toxic than laboratory-extracted pore waters. These data suggest that sediment-associated Mn may impact early-life stages of robust redhorse in the Oconee River.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Lasier, P., Winger, P., Bogenrieder, K., and Shelton, J., 2000, Impacts of toxic thresholds of sediment-associated contaminants to robust redhorse (Moxostoma robustum) in the Lower Oconee River: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","productDescription":"213 (abstract PTP111)","startPage":"213 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202061,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a04e4b07f02db5f8557","contributors":{"authors":[{"text":"Lasier, P.","contributorId":42331,"corporation":false,"usgs":true,"family":"Lasier","given":"P.","affiliations":[],"preferred":false,"id":340751,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Winger, P.","contributorId":91598,"corporation":false,"usgs":true,"family":"Winger","given":"P.","affiliations":[],"preferred":false,"id":340753,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bogenrieder, K.","contributorId":90432,"corporation":false,"usgs":true,"family":"Bogenrieder","given":"K.","affiliations":[],"preferred":false,"id":340752,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shelton, J.

Previously we reported significant correlations among four hepatic microsomal dealkylases and CYP1A in these turtles. Herein we compare ethoxyresorufin-O-dealkylase (EROD) and methoxyROD (MROD) to tissue contaminant concentrations. For Fifty-four of these turtles, muscle, fat body and liver tissues were assessed for PCBs and 20 organochlorine analytes and hepatic microsomal dealkylases. Of the contaminants analyzed, only DDE, dieldrin, oxychlordane, trans-nonachlor and PCB 1260 were detected in >25% of each sample type. When EROD and MROD activities were compared to tissue values for these contaminants, they were found to correlate significantly only to DDE, dieldrin and trans-nonachlor. For an 18 female subset of these turtles, serum PCBs and organochlorine pesticides, egg, fat body and liver dioxins and furans, and hepatic microsomal dealkylases were assessed. EROD and MROD both correlated significantly to serum PCB 105, PCB 138 and DDE, and to egg total PCBs. EROD and MROD did not correlate significantly with liver dioxins and furans, but there were significant correlations between EROD and egg and fat body dioxins and furans, and MROD and fat body dioxins and furans. It is expected that CYP1A-type inducers such as certain PCBs, and halogenated dioxins and furans, but not organochlorine pesticides, would be inducers in turtles. Presumably the correlation of monooxygenase with organochlorine pesticides is fortuitous, and toxic equivalencies are being calculated using a number of systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Two-part article.

If so, the functions of plumage (e.g. communication for mating or territorial defense), may be compromised by exposure to such compounds. Polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental toxins that can disrupt endocrine function in laboratory animals. Captive American kestrels (Falco sparverius) were fed PCBs (Aroclor 1242) at 6 and 60 ppm, thyroxine at 10 ppm, estradiol at 1.4 ppm, and a thyroid hormone blocker (propylthiouracil: PTU) at 2000 ppm, mixed in their normal diet. Plumage characteristics measured included: the width of the black subterminal band on the tail, brightness (a composite index of hue and saturation), reflectance from 230 - 800 nm (measured on a reflectance spectrophotometer), the pattern of feather loss and regrowth on the tail and wing, and the timing of onset and the duration of molt. PCB-treated birds did not differ from controls, but birds treated with thyroxine were significantly different from those dosed with estradiol or PTU in the width of subterminal tail bands, reflectance, and duration of molt. Thus, although hormone treatments did modify some of the plumage characteristics we measured, PCB treatments at these exposure levels did not.

Nestling Tree Swallows were also collected from five sites with differing levels of contaminants. Liver samples were taken and stored at -80C until microsome preparation and monooxygenase (MO) assay. Skin and heart samples were placed in buffered formalin until immunohistochemical (IMHC) analysis for cytochrome P4501A (CYP1A). Scaup treated with BNF at 20 or 100 mg/kg body weight showed approximately 20- to 65-fold increases in four MOs. Responses of two of the four MOs were as high at 20 mg/kg as at 100mg/kg. There was no IMHC response in the vehicle-injected ducks, while in skin the IMHC response was the same for both dose levels of BNF and in heart there was response in two of four samples at 20 mg/kg and in all five samples at 100mg/kg. Tree Swallows injected with BNF at 100, but not at 20 mg/kg showed significant increases (ca.5-fold) in two MO activities. There was no IMHC response in control swallows. In skin and heart there were IMHC responses in one of five swallows at 20 mg/kg and four of five swallows at 100mg/kg. There was poor correlation between individual skin IMHC responses and MO activities and PCB concentrations in 47 field-collected Tree Swallow samples, but 14 of the 16 skin samples with positive IMHC responses were from the location with the highest MO activities and PCB concentrations. Although present data do not allow construction of significant dose response curves, the responses in skin make it well worth continuing study on this potential nonlethal technique for biomonitoring contaminant exposure of birds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Melancon, M.J., Kutay, A., Woodin, B.R., and Stegeman, J.J., 2000, Evaluating cytochrome P450 in birds by monooxygenases and immunohistochemistry: possible nonlethal assessment by skin immunohistochemistry: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","productDescription":"44 (abstract 186)","startPage":"44 (abstra","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202176,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fa821","contributors":{"authors":[{"text":"Melancon, M.

During major storm events, raw sewage from the WWTF is released directly into the stream. The headwaters of the stream also receive non-point surface runoff from urban areas. RBP analyses, which included benthos, fish and habitat evaluations, and SQT, including the benthos (from the RBP), contaminant analyses (metals, organochlorine pesticides, PCBs and PAHs) andl toxicity tests of depositional sediment (exposures of Hyalella azteca to solid-phase sediment and pore water) were conducted at five sites on the stream (two upstream of the WWTF and three downstream). The stream has been channelized throughout its entire length, resulting in high, unstable banks, degraded stream channel, and unstable substratum. RBP analyses indicated that the two stations upstream of the WWTF were degraded due to poor physical habitat quality (unstable benthic substratum and lack of fish habitat). The SQT also showed reduced habitat quality at the two stations above the WWTF, but the cause was attributed to high concentrations of PAHs and metals in the sediments. The increased discharge and stabilized base flow provided by the WWTF improved habitat quality downnstream, although conditions were still impaired due to the habitat alteration. Though the causes of degradation were attributed to different factors (physical habitat vs. contamination), there was close concordance between the RBP and SQT in identifying the degraded sites in this stream. The combination of these two procedures provides a robust examination of environmental quality utilizing the weight of evidence approach.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Dale, F., 2000, Influence of calcium on the distribution of the pheasant in North America: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21, p. 316-323.","productDescription":"291 (abstract PHA070)","startPage":"316","endPage":"323","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201781,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e6e4b07f02db5e7395","contributors":{"authors":[{"text":"Dale, F.H.","contributorId":74473,"corporation":false,"usgs":true,"family":"Dale","given":"F.H.","email":"","affiliations":[],"preferred":false,"id":332238,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5220380,"text":"5220380 - 2000 - Tumor prevalence and biomarkers in brown bullheads (Ameiurus nebulosus) from the tidal Potomac River watershed [poster]","interactions":[],"lastModifiedDate":"2012-02-02T00:15:29","indexId":"5220380","displayToPublicDate":"2010-06-16T12:18:28","publicationYear":"2000","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3410,"text":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","active":true,"publicationSubtype":{"id":10}},"title":"Tumor prevalence and biomarkers in brown bullheads (Ameiurus nebulosus) from the tidal Potomac River watershed [poster]","docAbstract":"Associations between contaminant exposure and liver and skin tumor prevalence were evaluated in brown bullheads (Ameiurus nebulosus) from the tidal Potomac River watershed.

The history of the Refuge is reviewed and its physical and biological characteristlcs summarized.. The methods of study used during the investigation mcluded: periodic censuses of a representative 304-acre study area over a two-year period; a census of the breeding population of the entire. Refuge during one year; detailed population studies of representative habitats during the breeding season; censuses of the wintering population of. the entire Refuge during two years; general surveys of wintering populations for seven years; and general observations of seasonal changes in bird populatlons over a fourteen-year period, including data from an extensive banding program and from many special types of censuses. The phenology of the Refuge is described in conslderable detail throughout the year, with special attention given to major fluctuatIons in bIrd populations as correlated with climatic changes and with seasonal aspectlon. of the vegetation. The component specIes of birds m the more important migration waves are listed. Figures approximating the Refuge breeding and wmtering populations are given, while indices representing the relative abundance of bird populations, based on figures from the two-year seasonal populatlon study, were obtained for the entire year. The greatest variety of species as well as the greatest number of individuals occurred on the Refuge during the migration .periods in spring and fall, the variety of species being slightly higher in spring than in fa!l, while the population of individuals was considerably higher in fall. Wmtering and breeding populations were low and relatively stable compared to the populations at other seasons.The ecological affinities of the bird populations differed greatly from one season to another. Species characteristic of edge habitats were much more numerous in winter, while forest species were predominant in summer. Insectivorous species comprised a large proportion (40 to 60 percent) of the total population during the warmer months, but were of minor importance in winter. The greatest number of species of birds on the Refuge occurred during the population peaks of insectivorous species, while the largest number of individuals was found during the population peaks of omnivorous and herbivorous species. The population peaks of insectivorous species were found to occur much later in spring and considerably earlier in fall than the. corresponding peaks of omnivorous and herbivorous species. The Fringillidae contributed the greatest number of individuals in winter, while the Parulidae was the most important family (numerically) in summer. Water birds and marsh birds were relatively unimportant throughout the year, due to the scarcity of suitable habitats. Permanent resident species were found to vary from about one-fifth to slightly less than one-half of the total population throughout the year, although many individuals of these species were either transients or part-time residents. Summer residents and winter residents were more abundant than permanent residents during their respective periods of occurrence. During the greater part of the migration period, transient species were found to comprise only 10 to 20 percent of the total population. transient individuals of all species would account for a much larger proportion of the population at this time. After comparing the results of these investigations with similar studies in other areas, it is believed that the seasonal population changes on the Patuxent Research Refuge are fairly representative of those occurring throughout the Middle Atlantic and East-central States.

The oil forms a barrier at the air-water interface, which suffocates air-breathing insects. There are few published studies on non-target effects of GB-1111 but the product label warns that ?GB-1111 is toxic to fish and other aquatic organisms.? Fertile eggs of mallards (Anas platyrhynchos) and bobwhite (Colinus virginianus) were incubated in the laboratory, and treated on days 4 or 11 of incubation with external applications equivalent to either 0, 1/3, 1, 3, or 10 times the maximum rate (5 gal/A) of field application of GB-1111. Hatching success was significantly reduced in mallards treated on day 4 or day 11 at 3 and 10 times the maximum field application, with a calculated approximate LD50 of 1.9 times the maximum field application. Most mortality occurred within a week of treatment. Hatching success of bobwhite was only reduced at the highest level of treatment. Other effects at this level in bobwhite included a significant increase in incidence of abnormal embryos/ hatchlings, lower body and liver weights of hatchlings and a two-fold increase in hepatic microsomal P450-associated monooxygenase activity (EROD) in hatchlings. Recommended rates of field application of GB-1111 are potentially toxic to mallard embryos, especially under conditions of larvicide drift or spray overlap, but unlikely to impair the survival or development of bobwhite embryos.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Stickel, W.H., 2000, Effects of the mosquito larvicide GB-1111 on mallard and bobwhite embryos: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","productDescription":"230.

As such, the impact of endocrine disrupting chemicals (EDCs) can greatly differ across avian species. Precocial species, such as Japanese quail appear to be most sensitive to EDC effects during embryonic development, particularly sexual differentiation. A great deal is known about the ontogeny of Japanese quail (Coturnix japonica) relative to endocrine, neuro-endocrine, and behavioral components of reproduction. Therefore, this species provides an excellent model for understanding effects of EDCs on reproductive biology with exposure at specific stages of the life cycle. The purpose of these experiments was to conduct a 1- or 2- generation experiment with positive or negative control chemicals and to determine changes in selected end points. Japanese quail embryos were exposed to estradiol benzoate (EB; positive control) in a 2-generation design or to fadrozole (FAD; negative control) in a 1-generation design. Embryonic EB treatment resulted in significant reductions (p< 0.5) in hen day production (90.2 vs 54.1; control vs EB, resp.) and fertility (85.3 vs 33.4%, control vs EB, resp.). Males showed sharply reduced courtship and mating behaviors as well as increased lag time (26 vs 148 sec; control vs EB) in behavioral tests. Fadrozole exposure resulted in reduced hatchability of fertile eggs, particularly at higher doses. There were no significant effects on courtship and mating behavior of males although males showed an increased lag time in their responses, nally, a behavioral test for studying motor and fear responses in young chicks was used; chicks exposed to an estrogenic pesticide (methoxychlor) showed some deficits. In summary, the use of appropriate and reliable end points that are responsive to endocrine disruption are critical for assessment of EDCs.

Thirty bullheads (>260 mm) were collected from (1) Quantico embayment, near a Superfund site which released organochlorine contaminants; (2) Neabsco Creek, a tributary with petroleum inputs from runoff and marinas; and (3) Anacostia River (spring and fall), an urban tributary designated as a Chesapeake Bay Region of Concern, contaminated with PCBs, PAHs, and organochlorine pesticides. Fish were collected from the Tuckahoe River, as a reference. Cytochrome P450 activity, bile PAH metabolites, and muscle organochlorine pesticide/PCB concentrations were measured in randomly-selected individuals and sediment contaminants were analyzed. We found statistically significant differences in liver tumor prevalences: Anacostia (spring)-50%, Anacostia (fall)-60%, Neabsco-17%, Quantico-7%, Tuckahoe-10%. Skin tumor prevalences were significantly different: Anacostia (spring)-37%, Anacostia (fall)-10%, Neabsco-3%, Quantico-3%, Tuckahoe-0%. Tumor prevalence in Anacostia bullheads warrants concern and was similar to those at highly contaminated sites in the Great Lakes. There was evidence of higher PAH exposure in Anacostia fish but a cause-effect linkage cannot be established. Fish tumor surveys, with histopathological examination of internal and external organs, are recommended for monitoring the status of Regions of Concern.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Pinkney, A., Harshbarger, J., May, E., and Melancon, M.J., 2000, Tumor prevalence and biomarkers in brown bullheads (Ameiurus nebulosus) from the tidal Potomac River watershed [poster]: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","startPage":"165 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201839,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a49e4b07f02db623fc8","contributors":{"authors":[{"text":"Pinkney, A.E.","contributorId":87501,"corporation":false,"usgs":true,"family":"Pinkney","given":"A.E.","affiliations":[],"preferred":false,"id":340759,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harshbarger, J.C.","contributorId":18303,"corporation":false,"usgs":true,"family":"Harshbarger","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":340758,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"May, E.B.","contributorId":6406,"corporation":false,"usgs":true,"family":"May","given":"E.B.","email":"","affiliations":[],"preferred":false,"id":340757,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Melancon, M.

During major storm events, raw sewage from the WWTF is released directly into the stream. The headwaters of the stream also receive non-point surface runoff from urban areas. RBP analyses, which included benthos, fish and habitat evaluations, and SQT, including the benthos (from the RBP), contaminant analyses (metals, organochlorine pesticides, PCBs and PAHs) andl toxicity tests of depositional sediment (exposures of Hyalella azteca to solid-phase sediment and pore water) were conducted at five sites on the stream (two upstream of the WWTF and three downstream). The stream has been channelized throughout its entire length, resulting in high, unstable banks, degraded stream channel, and unstable substratum. RBP analyses indicated that the two stations upstream of the WWTF were degraded due to poor physical habitat quality (unstable benthic substratum and lack of fish habitat). The SQT also showed reduced habitat quality at the two stations above the WWTF, but the cause was attributed to high concentrations of PAHs and metals in the sediments. The increased discharge and stabilized base flow provided by the WWTF improved habitat quality downnstream, although conditions were still impaired due to the habitat alteration. Though the causes of degradation were attributed to different factors (physical habitat vs. contamination), there was close concordance between the RBP and SQT in identifying the degraded sites in this stream. The combination of these two procedures provides a robust examination of environmental quality utilizing the weight of evidence approach.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Winger, P., Lasier, P., and Bogenrieder, K., 2000, Influence of calcium on the distribution of the pheasant in North America: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","startPage":"291 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202966,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e6e4b07f02db5e779a","contributors":{"authors":[{"text":"Winger, P.","contributorId":91598,"corporation":false,"usgs":true,"family":"Winger","given":"P.","affiliations":[],"preferred":false,"id":340756,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lasier, P.","contributorId":42331,"corporation":false,"usgs":true,"family":"Lasier","given":"P.","affiliations":[],"preferred":false,"id":340754,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bogenrieder, K.","contributorId":90432,"corporation":false,"usgs":true,"family":"Bogenrieder","given":"K.","affiliations":[],"preferred":false,"id":340755,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5224167,"text":"5224167 - 2000 - Seventeenth breeding-bird census. 34.

If so, the functions of plumage (e.g. communication for mating or territorial defense), may be compromised by exposure to such compounds. Polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental toxins that can disrupt endocrine function in laboratory animals. Captive American kestrels (Falco sparverius) were fed PCBs (Aroclor 1242) at 6 and 60 ppm, thyroxine at 10 ppm, estradiol at 1.4 ppm, and a thyroid hormone blocker (propylthiouracil: PTU) at 2000 ppm, mixed in their normal diet. Plumage characteristics measured included: the width of the black subterminal band on the tail, brightness (a composite index of hue and saturation), reflectance from 230 - 800 nm (measured on a reflectance spectrophotometer), the pattern of feather loss and regrowth on the tail and wing, and the timing of onset and the duration of molt. PCB-treated birds did not differ from controls, but birds treated with thyroxine were significantly different from those dosed with estradiol or PTU in the width of subterminal tail bands, reflectance, and duration of molt. Thus, although hormone treatments did modify some of the plumage characteristics we measured, PCB treatments at these exposure levels did not.

Previously we reported significant correlations among four hepatic microsomal dealkylases and CYP1A in these turtles. Herein we compare ethoxyresorufin-O-dealkylase (EROD) and methoxyROD (MROD) to tissue contaminant concentrations. For Fifty-four of these turtles, muscle, fat body and liver tissues were assessed for PCBs and 20 organochlorine analytes and hepatic microsomal dealkylases. Of the contaminants analyzed, only DDE, dieldrin, oxychlordane, trans-nonachlor and PCB 1260 were detected in >25% of each sample type. When EROD and MROD activities were compared to tissue values for these contaminants, they were found to correlate significantly only to DDE, dieldrin and trans-nonachlor. For an 18 female subset of these turtles, serum PCBs and organochlorine pesticides, egg, fat body and liver dioxins and furans, and hepatic microsomal dealkylases were assessed. EROD and MROD both correlated significantly to serum PCB 105, PCB 138 and DDE, and to egg total PCBs. EROD and MROD did not correlate significantly with liver dioxins and furans, but there were significant correlations between EROD and egg and fat body dioxins and furans, and MROD and fat body dioxins and furans. It is expected that CYP1A-type inducers such as certain PCBs, and halogenated dioxins and furans, but not organochlorine pesticides, would be inducers in turtles. Presumably the correlation of monooxygenase with organochlorine pesticides is fortuitous, and toxic equivalencies are being calculated using a number of systems.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Environmental sciences in the 21st century: Paradigms, opportunities, and

Activities of nine plasma and tissue enzymes, and concentrations of other plasma and tissue constituents were measured for black-crowned night-heron, Nycticorax nycticorax, (BCNH) and snowy egret, Egretta thula, (SE) nestlings from two high mercury sites and one low mercury site. Geometric mean blood Hg concentrations for BCNHs at the high mercury sites were 2.6 and 2.8 ppm (ww) and 0.6 ppm at the low mercury site. Blood concentrations for SEs were 3.6 and 1.9 ppm at the high mercury sites and 0.7 ppm at the low mercury site. In BCNHs plasma glutathione peroxidase (GSH peroxidase) activity was lower in both high mercury sites relative to the low mercury site. Butyryl cholinesterase (BuChe), ALT, glutathione reductase (GSSG-reductase) and LDH-L activities were lower in one high mercury site. In SEs significant differences were lower BuChe and LDH-L, but elevated GGT activities. Evidence of renal stress in both species at high mercury sites included increased plasma uric acid, blood urea nitrogen, and creatinine concentrations as well as oxidative stress in the kidney tissue itself where oxidized glutathione increased. A number of the mercury site-related effects, including decreased plasma GSH-peroxidase and hepatic G-6-PDH activities, higher GSSG-reductase activity, and lower hepatic concentrations of reduced thiols have been reported in methylmercury feeding studies with great egrets and mallards. These findings suggest the utility of herons and egrets for monitoring mercury sites.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Hoffman, D.J., Henny, C.J., Hill, E.F., Keith, J., and Grove, R.A., 2000, Seasonal distribution of bird populations at the Patuxent Research Refuge: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","startPage":"229.

There is a need to evaluate endocrine endpoints as potential markers for contaminant effects, and to determine their effectiveness and sensitivity when applied to wildlife. To this end, a three generational test was conducted using the Japanese quail (Coturnix japonica) and a proven estrogenic PCB. Birds were exposed during embryonic development via maternal deposition and/or direct egg injection at day 4. Standard measures of reproductive success and productivity used in toxicological studies, as well as multiple measures of physiological and behavioral responses used in endocrine studies were collected. Long term effects on growth and apparent development were similar between treated and control offspring. Fertility of treated eggs decreased from 75%+ 4.4 (x + se) for P1, to 59% + 12.5 for F1 and 54% + 14.2 for F2. All paired control birds mated to produce viable eggs, whereas 27 % of the F1 and 41 % of the F2 treated pairs failed to produce at least 1 viable egg. Although some decreases in productivity can be related to direct toxic exposure, the response from one generation to the next was not linear with treatment, indicating a potential effect from behavioral or other endocrine alterations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Society of Environmental Toxicology and Chemistry, annual meeting abstract book","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Environmental Sciences in the 21st Century: Paradigms, opportunities, and challenges, Nashville, Tennessee, November 12-16.","usgsCitation":"Henry, P., Russek-Cohen, E., Casey, C., Abdelnabi, M., and Ottinger, M.A., 2000, Evaluating endocrine endpoints relative to reproductive success in Japanese quail exposed to estrogenic chemicals [poster]: Society of Environmental Toxicology and Chemistry, annual meeting abstract book, v. 21.","startPage":"263 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fb0da","contributors":{"authors":[{"text":"Henry, P.F.P.","contributorId":14531,"corporation":false,"usgs":true,"family":"Henry","given":"P.F.P.","email":"","affiliations":[],"preferred":false,"id":340730,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Russek-Cohen, E.","contributorId":11717,"corporation":false,"usgs":true,"family":"Russek-Cohen","given":"E.","email":"","affiliations":[],"preferred":false,"id":340729,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Casey, C.S.","contributorId":28340,"corporation":false,"usgs":true,"family":"Casey","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":340731,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abdelnabi, M.A.","contributorId":41939,"corporation":false,"usgs":true,"family":"Abdelnabi","given":"M.A.","affiliations":[],"preferred":false,"id":340732,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ottinger, M.

We investigated the effects of clearcut stand size on species richness, reproductive effort, and relative abundance of scrub-successional birds and the entire bird assemblage at the Savannah River Site in South Carolina. We used standardized mist-net grids to mark and recapture birds in clearcuts replanted with longleaf pine (Pinus palustris) in stands of 2 to 57 ha that were two to six years old. Species richness for the entire bird assemblage was not explained by stand size (P = 0.67), stand age (P = 0.95), or the interaction of these two variables (P = 0.90). Similarly, species richness of scrub-successional birds was not explained by stand size (P = 0.63), stand age (P = 0.55), or the interaction of stand size and stand age (P = 0.35). Regressing species richness on clearcut stand size, we found a significant negative relationship between these variables for the entire bird assemblage (P = 0.01) and for scrub-successional birds (P = 0.02). The ratio of juveniles to adults in mist-net samples varied by year (P = 0.04), but neither clearcut size (P = 0.23) nor the interaction of clearcut size and year (P = 0.25) was related to the ratio of juveniles to adults in the sample. We found no relationship between the frequency of capture of any category of birds and stand size (scrub-successional, P = 0.52; woodland, P = 0.77; combined sample, P = 0.55). Neither bird-species richness, reproductive effort, nor relative abundance differed across clearcut stand sizes. Clearcut stand size does not appear to be an important management variable if variation in species richness, reproductive effort, or relative abundance are objectives. We suggest that even-aged forestry is a useful tool for managing birds in the southeastern United States.

Sediment ingestion has recently been identified as an important exposure route for toxicants in waterfowl. The effects of lead-contaminated sediment from the Coeur d'Alene River Basin (CDARB) in Idaho on posthatching development of Canada geese (Branta canadensis) were examined for 6 wk. Day-old goslings received either untreated control diet, clean sediment (48%) supplemented control diet, or CDARB sediment (3449 mug/g lead) supplemented diets at 12%, 24%, or 48%. The 12% CDARB diet resulted in a geometric mean blood lead concentration of 0.68 ppm (ww), with over 90% depression of red blood cell ALAD activity and over fourfold elevation of free erythrocyte protoporphyrin concentration. The 24% CDARB diet resulted in blood lead of 1.61 ppm with decreased hematocrit, hemoglobin, and plasma protein in addition to the effects just described. The 48% CDARB diet resulted in blood lead of 2.52 ppm with 22% mortality, decreased growth, and elevated plasma lactate dehydrogenase-L (LDH-L) activity. In this group the liver lead concentration was 6.57 ppm (ww), with twofold increases in hepatic lipid peroxidation (thiobarbituric acid-reactive substances, TBARS) and in reduced glutathione concentration; associated effects included elevated glutathione reductase activity but lower protein-bound thiols concentration and glucose-6-phosphate dehydrogenase (G-6-PDH) activity. The kidney lead concentration in this group was 14.93 ppm with subacute renal tubular nephrosis in one of the surviving goslings. Three other geese in this treatment group exhibited calcified areas of marrow, and one of these displayed severe chronic fibrosing pancreatitis. Lead from CDARB sediment accumulated less readily in gosling blood and tissues than reported in ducklings but at given concentrations was generally more toxic to goslings. Many of these effects were similar to those reported in wild geese and mallards within the Coeur d'Alene River Basin.

The seismovolcanic signals associated with the volcanic activity of Deception Island (Antarctica), recorded during three Antarctic summers (1994–1995, 1995–1996 and 1996–1997), are analyzed using a dense small-aperture (500 m) seismic array. The visual and spectral classification of the seismic events shows the existence of long-period and hybrid isolated seismic events, and of low-frequency, quasi-monochromatic and spasmodic continuous tremors. All spectra have the highest amplitudes in the frequency band between 1 and 4 Hz, while hybrids and spasmodic tremors have also significant amplitudes in the high-frequency band (4–10 Hz). The array analysis indicates that almost all the well-correlated low-frequency signals share similar array parameters (slowness and back azimuth) and have the same source area, close to the array site. The polarization analysis shows that phases at high-frequency are mostly composed of P waves, and those phases dominated by low frequencies can be interpreted as surface waves. No clear shear waves are evidenced. From the energy evaluation, we have found that the reduced displacement values for surface and body waves are confined in a narrow interval. Volcano-tectonic seismicity is located close to the array, at a depth shallower than 1 km. The wave-field properties of the seismovolcanic signals allow us to assume a unique source model, a shallow resonating fluid-filled crack system at a depth of some hundreds of meters. All of the seismic activity is interpreted as the response of a reasonably stable stationary geothermal process. The differences observed in the back azimuth between low and high frequencies are a near-field effect.

Fish were obtained from the Quantico embayment, near a Superfund site that released polychlorinated biphenyls (PCBs) and DDT compounds; Neabsco Creek,.a tributary with petroleum inputs from upstream areas and marinas; and the Anacostia River (both in spring and fall),where sediment is contaminated with polynuclear aromatic hydrocarbons (PAHs), PCBs, and organochlorine pesticides. Fish were also collected from the Tuckahoe River, on the Eastern Shore of Maryland, as a reference. Fish were necropsied and examined grossly and histopathologically for skin and liver neoplasms. Cytochrome P450 activity, bile PAH metabolites, and muscle organochlorine pesticide/PCB concentrations were determined in randomly selected individuals. There were significant differences among sites in liver tumor prevalence: Anacostia (spring)-50%, Anacostia (fall)-60%, Neabsco-17%, Quantico-7%, Tuckahoe-10%. Skin tumor prevalences were also significantly different: Anacostia (spring)-37%, Anacostia (fall)-10%, Neabsco-3%, Quantico-3%, Tuckahoe-0%. Tumor prevalences in Anacostia fish were comparable to those at contaminated sites in the Great Lakes. PAH concentrations were higher in Anacostia sediments than at the other sites and there were significantly higher concentrations of PAH metabolites in bile of the Anacostia fish. At present, there are insufficient data, however, to establish a cause-effect linkage with a particular class of contaminants. Tumor surveys in selected species are recommended for monitoring the status and remediation of Regions of Concern and other areas in the Chesapeake Bay watershed.","language":"English","publisher":"U.S. Fish and Wildlife Service, Chesapeake Bay Field Office","publisherLocation":"Annapolis, MD","usgsCitation":"Pinkney, A., Harshbarger, J., May, E., and Melancon, M.J., 2000, Tumor Prevalence and Biomarkers of Exposure and Response in Brown Bullheads (Ameiurus nebulosus) from the Tidal Potomac River Watershed, various.","productDescription":"various","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a49e4b07f02db62410c","contributors":{"authors":[{"text":"Pinkney, A.E.","contributorId":87501,"corporation":false,"usgs":true,"family":"Pinkney","given":"A.E.","affiliations":[],"preferred":false,"id":327292,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harshbarger, J.C.","contributorId":18303,"corporation":false,"usgs":true,"family":"Harshbarger","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":327291,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"May, E.B.","contributorId":6406,"corporation":false,"usgs":true,"family":"May","given":"E.B.","email":"","affiliations":[],"preferred":false,"id":327290,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Melancon, M.

Each review was prepared at the request of environmental specialists of the U.S. Fish and Wildlife Service and each contained specific information on the following: mirex, cadmium, carbofuran, toxaphene, selenium, chromium, polychlorinated biphenyls, dioxins, diazinon, mercury, polycyclic aromatic hydrocarbons, arsenic, chlorpyrifos, lead, tin, index issue, pentachlorophenol, atrazine, molybdenum, boron, chlordane, paraquat, cyanide, fenvalerate, diflubenzuron, zinc, famphur, acrolein, radiation, sodium monofluoroacetate, planar PCBs, silver, copper, nickel, and a cumulative index to chemicals and species. Each report reviewed and synthesized the technical literature on a single contaminant and its effects on terrestrial plants and invertebrates, aquatic plants and animals, avian and mammalian wildlife, and other natural resources. The subtopics include contaminant sources and uses; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects, where appropriate; lethal and sublethal effects, including effects on survival, growth, reproduction, metabolism, mutagenicity, teratogenicity, and carcinogenicity; proposed criteria for the protection of human health and sensitive natural resources; and recommendations for additional research.","language":"English","publisher":"U.S. Fish and Wildlife Service","publisherLocation":"Laurel, MD","usgsCitation":"Eisler, R., Munro, R.E., Loges, L., Boone, K., Paul, M., and Garrett, L., 2000, Contaminant Hazard Reviews (compilation): Contaminant Hazard Reviews, CD-Rom.","productDescription":"CD-Rom","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202864,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":276537,"type":{"id":15,"text":"Index Page"},"url":"https://www.pwrc.usgs.gov/eisler/index.cfm"},{"id":276538,"type":{"id":11,"text":"Document"},"url":"https://www.pwrc.usgs.gov/eisler/reviews.cfm"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afde4b07f02db696ebb","contributors":{"authors":[{"text":"Eisler, R.","contributorId":51869,"corporation":false,"usgs":true,"family":"Eisler","given":"R.","affiliations":[],"preferred":false,"id":327279,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munro, R.

However, the problems associated with research involving populations and groups of species or large and complex geographic areas, especially in terrestrial environments, are well known within the scientific community. With the previous thoughts in mind, an interactive symposium was held at the University of Maryland in October 1998. The purpose of the symposium was to review and critically evaluate our understanding of the effects of contaminants on terrestrial vertebrates at levels of organization above that of the individual. Invited background and technical presentations provided a common baseline of information for symposium participants. Discussion groups were then asked to critically evaluate the topics of two technical sessions. Several presentations of recent or ongoing research provided participants with examples of current approaches to assessments of the effects of contaminants on terrestrial vertebrates at the population or higher level of organization. The book consists of 10 chapters written by presenters at the symposium and three chapters conveying the reports of discussion group.","language":"English","publisher":"Society of Environmental Toxicology and Chemistry","publisherLocation":"Pensacola, FL","collaboration":"OCLC: 43286528.
