Avian Influenza: Human Pandemic Concerns, Donna K. Carver, Elizabeth A. Krushinskie

Zoonotics and Wildlife Disease: Publications

The likelihood that the next human influenza pandemic virus will emerge from the Asian strain of the H5N1 high pathogenic bird influenza virus that is causing widespread outbreaks in Eurasia remains unknown. (See Glossary for italicized terms.) Because these bird influenza outbreaks remain primarily an animal disease, there is hope that a human pandemic can be prevented. Eradication of the H5N1 high pathogenic bird influenza virus needs to occur at the farm level in the countries where it is currently circulating. Funding of prevention, surveillance, and eradication efforts in the countries where outbreaks are occurring or in at-risk countries will …

Chronic Wasting Disease Of Elk And Deer And Creutzfeldt-Jakob Disease Comparative Analysis Of The Scrapie Prion Protein, Zhiliang Xie, Katherine I. O'Rourke, Zhiqian Dong, Allen L. Jenny, Julie A. Langenberg, Ermais D. Belay, Lawrence B. Schonberger, Robert B. Petersen, Wenquan Zou, Quingzhong Kong, Pierluigi Gambetti, Shu G. Chen

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD), a transmissible prion disease that affects elk and deer, poses new challenges to animal and human health. Although the transmission ofCWDto humans has not been proven, it remains a possibility. If this were to occur, it is important to know whether the “acquired” human prion disease would show a phenotype including the scrapie prion protein (PrP^Sc) features that differ from those associated with human sporadic prion disease. In this study, we have compared the pathological profiles and PrP^Sc characteristics in brains of CWD-affected elk and deer with those in subjects with sporadic Creutzfeldt-Jakob …

Marine Species, Paul R. Armsworth, Carrie V. Kappel, Fiorenza Micheli, Eric P. Bjorkstedt

United States Department of Commerce: Staff Publications

The 4.1 million square miles of ocean inside the 200-mile exclusive economic zone around the United States surpasses the 3.6 million square miles total land area within federal jurisdiction (Lindholm and Barr 2001). The coastal oceans contain a great diversity of habitat types and ecosystems. These habitats are associated with particular substrate features such as coral reefs, sea grass beds, rocky shores and soft-bottom habitats, and also with persistent oceanographic features such as frontal convergence zones and upwelling regions.

Our marine ecosystems contain unique and rich biotas. At higher taxonomie levels, biodiversity is much richer in the marine environment than …

Working Seascapes, Paul R. Armsworth, Carrie V. Kappel, Fiorenza Micheli, Eric P. Bjorkstedt

United States Department of Commerce: Staff Publications

Marine species are being listed under the Endangered Species Act with increasing frequency and this trend can be expected to continue (Armsworth et al. 2006). The taxonomie focus of marine listings is also diversifying (Armsworth et al. 2006). Despite long-held assumptions that life his tory characteristics of so me marine species render them less vulnerable to extinction, anthropogenie impacts to marine ecosystems have imperiled a growing number of species. In this chapter, we review both the threats endangering marine species and some of the strategies being employed to mitigate those threats.

Listing decisions reveal the relative importance of different threats …

Assessing Effects Of Alternative Agricultural Practices On Wildlife Habitat In Iowa, Usa, Mary Santelmann, Kathryn Freemark, Jean Sifneos, Denis White

United States Environmental Protection Agency: Publications

A habitat-change model was used to compare past, present, and future land cover and management practices to assess potential impacts of alternative agricultural practices on wildlife in two agricultural watersheds, Walnut Creek and Buck Creek, in central Iowa, USA. This approach required a habitat map for each scenario based on soil type and land cover, a list of resident species, and an estimate of the suitability of each of 26 habitat classes for every species. Impact on wildlife was calculated from median percent change in habitat area relative to the present. Habitat classes with the highest species richness for native …

Mode Of Action In Relevance Of Rodent Liver Tumors To Human Cancer Risk, Michael P. Holsapple, Henri C. Pitot, Samuel H. Cohen, Alan R. Boobis, James E. Klaunig, Timothy Pastoor, Vicki L. Dellarco, Yvonne P. Dragan

United States Environmental Protection Agency: Publications

Hazard identification and risk assessment paradigms depend on the presumption of the similarity of rodents to humans, yet species specific responses, and the extrapolation of high-dose effects to lowdose exposures can affect the estimation of human risk from rodent data. As a consequence, a human relevance framework concept was developed by the International Programme on Chemical Safety (IPCS) and International Life Sciences Institute (ILSI) Risk Science Institute (RSI) with the central tenet being the identification of a mode of action (MOA). To perform a MOA analysis, the key biochemical, cellular, and molecular events need to first be established, and the …

The Fathead Minnow In Aquatic Toxicology: Past, Present And Future, Gerald T. Ankley, Daniel L. Villeneuve

United States Environmental Protection Agency: Publications

This paper reviews the roles of the fathead minnow (Pimephales promelas) as a small fish model in the field of aquatic toxicology. The species has been (and is) extensively used both for regulatory testing and research, especially in North America. For example, tests with the fathead minnow, ranging from 48-h lethality through partial and full life-cycle assays, are routinely used for regulatory programs aimed at assessing potential risks of new chemicals such as high-production volume materials and pesticides, as well as impacts of complex mixtures like effluents. The species also has been used for a wide variety of …

Scientific Reports Of Soviet Whaling Expeditions In The North Pacific, 1955-1978, Yulia V. Ivashchenko, Phillip J. Clapham, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The translated and annotated materials in this volume constitute a collection of 18 formerly secret internal reports written by Soviet scientists working aboard whaling factory ships in the North Pacific. The reports cover the period from 1955 to 1978. During most of this time, the USSR was engaged in a massive campaign of illegal whaling worldwide; these illegal catches continued until introduction of the International Whaling Commission’s International Observer Scheme in 1972. The reports were copied from the archives of the Pacific Research and Fisheries Center (TINRO) in Vladivostok by Alfred A. Berzin, the former director of TINRO’s marine mammal …

Differential Expression Of Immune Response Genes In Steller Sea Lions (Eumetopias Jubatus): An Indicator Of Ecosystem Health?, Lizabeth Bowen, Brian Aldridge, Kimberlee Beckmen, Tom Gelatt, Lorrie Rea, Kathy Burek, Ken Pitcher, Jeffrey L. Stott

United States Department of Commerce: Staff Publications

Characterization of the polygenic and polymorphic features of the Steller sea lion major histocompatibility complex (MHC) provides an ideal window for evaluating immunologic vigor of the population and identifying emergence of new genotypes that reflect ecosystem pressures. MHC genotyping can be used to measure the potential immunologic vigor of a population. However, since ecosystem-induced changes to MHC genotype can be slow to emerge, measurement of differential expression of these genes can potentially provide real-time evidence of immunologic perturbations. MHC DRB genes were cloned and sequenced using peripheral blood mononuclear leukocytes derived from 10 Steller sea lions from southeast Alaska, Prince …

Relating Chronic Toxicity Responses To Population-Level Effects: A Comparison Of Population-Level Parameters For Three Salmon Species As A Function Of Low-Level Toxicity, Julann A. Spromberg, James P. Meador

United States Department of Commerce: Staff Publications

Standard laboratory toxicity tests assess the physiological responses of individual organisms to exposure to toxic substances under controlled conditions. Time and space restrictions often prevent the assessment of population-level responses to a toxic substance. Contaminants can affect various biological functions (e.g. growth, fecundity or behavior), which may alter different demographic traits, leading to population-level impacts. In this study,immune suppression, reproductive dysfunction and somatic growth impairment were examined using life history matrix models for coho salmon (Oncorhynchus kisutch), sockeye salmon (Oncorhynchus nerka) and chinook salmon (Oncorhynchus tshawytscha). Our intent was to gauge the relative magnitude …

Studies Of Beaked Whale Diving Behavior And Odontocete Stock Structure In Hawai‘I In March/April 2006, Robin W. Baird, Gregory S. Schorr, Daniel L. Webster, Daniel J. Mcsweeney, Sabre D. Mahaffy

United States Department of Commerce: Staff Publications

Small-boat surveys were undertaken in March/April 2006 off the west side of the island of Hawai‘i for the purposes of obtaining dive data from Blainville’s (Mesoplodon densirostris) and Cuvier’s (Ziphius cavirostris) beaked whales, as well as collecting biopsy samples and photo-identification of these and other species of odontocetes for studies of stock structure and residency patterns. There were 157 sightings of 13 species of odontocetes in 4,264 km of effort, with 120 genetic samples from seven species and over 29,000 photographs from 13 species obtained. Photographic matching to existing catalogs is currently underway for eight species. …

A Survey For Odontocete Cetaceans Off Kaua‘I And Ni‘Ihau, Hawai‘I, During October And November 2005: Evidence For Population Structure And Site Fidelity, Robin W. Baird, Gregory S. Schorr, Daniel L. Webster, Sabre D. Mahaffy, Anne B. Douglas, Antoinette M. Gorgone, Daniel J. Mcsweeney

United States Department of Commerce: Staff Publications

Considerable uncertainty exists regarding population structure and population sizes of most species of odontocetes in the Hawaiian Islands. A small-boat based survey for odontocetes was undertaken off the islands of Kaua‘i and Ni‘ihau in October and November 2005 to photoidentify individuals and collect genetic samples for examining stock structure. Field effort on 24 days covered 2,194 km of trackline. Survey coverage was from shallow coastal waters out to over 3,000 m depth, though almost half (47%) was in waters less than 500 m in depth. There were 56 sightings of five species of odontocetes: spinner dolphins (30 sightings); bottlenose dolphins …

Blue Whale (Balaenoptera Musculus) Sightings And Recordings South Of The Aleutian Islands, Shannon Rankin, Jay Barlow, Kathleen M. Stafford

United States Department of Commerce: Staff Publications

Blue whales have been sighted throughout the North Pacific Ocean (Mizroch et al. 1984), and were harvested around the Pacific Rim from Mexico to Japan (Fig. 1). The International Whaling Commission (IWC) currently recognizes only one stock of blue whales in the North Pacific (Donovan 1991); however, there may be up to five (reviewed in Stafford 2003). While past shipboard and aerial surveys in the Aleutian Island chain found no blue whales (Rice and Wolman 1982, Stewart et al. 1987), their contemporary presence in this area has been well documented by acoustic monitoring (Watkins et al. 2000, Stafford et al. …

Lessons From Monitoring Trends In Abundance Of Marine Mammals, Barbara L. Taylor, Melissa Martinez, Tim Gerrodette, Jay Barlow, Yvana N. Hrovat

United States Department of Commerce: Staff Publications

We assessed scientists’ ability to detect declines of marine mammal stocks based on recent levels of survey effort, when the actual decline is precipitous. We defined a precipitous decline as a 50% decrease in abundance in 15 yr, at which point a stock could be legally classified as “depleted” under the U.S. Marine Mammal Protection Act.We assessed stocks for three categories of cetaceans: large whales (n = 23, most of which are listed as endangered), beaked whales (n = 11, potentially vulnerable to anthropogenic noise), and small whales/dolphins/porpoises (n = 69, bycatch in fisheries and important abundant …

Continued Disappearance Of The Benthic Amphipod Diporeia Spp. In Lake Michigan: Is There Evidence For Food Limitation?, Thomas F. Nalepa, David L. Fanslow, Andrew J. Foley Iii, Gregory A. Lang, Brian J. Eadie, Michael A. Quigley

United States Department of Commerce: Staff Publications

Benthic surveys were conducted in the southern basin of Lake Michigan and throughout the lake to assess trends in benthic populations, emphasizing recent changes in densities of the benthic amphipod Diporeia spp. and dreissenid mussels. In the southern basin, Diporeia populations declined 89%, 91%, and 45% between 1993 and 2002 at sites <30, 31–50, and 51–90 m, respectively. Lakewide, the population declined 65% between 1994–1995 and 2000. Over the same time period, dreissenid densities, particularly Dreissena bugensis, increased. Intensive studies at 45 m sites in the southeastern region examined changes in lipid content, age structure, and benthic food inputs relative to the hypothesis that food limitation was a factor in Diporeia’s disappearance. As Diporeia densities declined to zero, length–weight remained unchanged, …

Shiga Toxin Of Enterohemorrhagic Escherichia Coli Type O157:H7 Promotes Intestinal Colonization, Cory M. Robinson, James F. Sinclair, Michael J. Smith, Alison D. O'Brien

Uniformed Services University of the Health Sciences

Enterohemorrhagic Escherichia coli (EHEC) 0157:H7 is a food-borne pathogen that can cause bloody diarrhea and, occasionally, acute renal failure as a consequence of Shiga toxin (Stx) production by the organism. Stxs are potent cytotoxins that are lethal to animals at low doses. Thus, Stxs not only harm the host but, as reported here, also significantly enhance the capacity of EHEC O157:H7 to adhere to epithelial cells and to colonize the intestines of mice. Tissue culture experiments showed that this toxin-mediated increase in bacterial adherence correlated with an Stx-evoked increase in a eukaryotic receptor for the EHEC O157:H7 attachment factor intimin.

Monoclonal Antibodies To Distinct Regions Of Human Myelin Proteolipid Protein Simultaneously Recognize Central Nervous System Myelin And Neurons Of Many Vertebrate Species, Edward A. Greenfield, Jay Reddy, Andrew Lees, Charissa A. Dyer, Omanand Koul, Khuong Nguyen, Shannon Bell, Nasim Kassam, Julian Hinojoza, Mary Jane Eaton, Marjorie B. Lees, Vijay K. Kuchroo, Raymond A. Sobel

Jay Reddy Publications

Myelin proteolipid protein (PLP), the major protein of mammalian CNS myelin, is a member of the proteolipid gene family (pgf). It is an evolutionarily conserved polytopic integral membrane protein and a potential autoantigen in multiple sclerosis (MS). To analyze antibody recognition of PLP epitopes in situ, monoclonal antibodies (mAbs) specific for different regions of human PLP (50–69, 100–123, 139–151, 178–191, 200–219, 264–276) were generated and used to immunostain CNS tissues of representative vertebrates. mAbs to each region recognized whole human PLP on Western blots; the anti-100–123 mAb did not recognize DM-20, the PLP isoform that lacks residues 116–150. All of …

Cougars In Kansas, Charles D. Lee, Alyssa E. Warneke, Mike Houts, Troy R. Livingston, Philip S. Gipson

United States Geological Survey: Staff Publications

The presence of the cougar (Puma concolor) in the state of Kansas is a controversial issue. Since 1999, 234 cougar sightings have been reported to the Extension Wildlife Specialist at Kansas State University. To those who have reported such sightings, the existence of cougars in Kansas is undeniable. Others, however, question the validity of such sightings as providing evidence of cougars. After surveying other governmental agencies and organizations, we discovered that acceptable identification criteria for rare or unusual felines included things beside sightings: voucher specimens, DNA from hair or scat, tracks, prey carcasses, and photographs or videos. The …

Historical And Current Status Of Elk In Kansas, Jonathan M. Conard, Philip S. Gipson, Matt Peek

United States Geological Survey: Staff Publications

Elk (Cervus elaphus) historically occurred throughout Kansas but were extirpated from the state around 1890. Free-ranging elk populations were reestablished in Kansas through reintroduction efforts on Cimarron National Grasslands from 1981-1990, and on Fort Riley Military Installation from 1986-1994. Current elk distributions in the state have not been published following these reintroduction efforts. The current and historical distribution of this species in Kansas is described.
