Long term productivity of canvasbacks (Aythya valisineria) in a snowpack-driven desert marsh
Kammie L. Kruse, James R. Lovvorn, John Y. Takekawa, Jeffrey Mackay
2003, The Auk (120) 107-119
Ruby Lake, Nevada, is a large palustrine wetland that hosts the southern-most major breeding population of Canvasbacks (Aythya valisineria). That arid marsh, fed by springs derived from mountain snowpack, differs in climate and hydrology from glaciated potholes of the northern prairies where most Canvasbacks breed. Fourteen years of nesting data...
Characterization of Pasteurella multocida isolates from wetland ecosystems during 1996 to 1999
M.D. Samuel, D.J. Shadduck, Diana R. Goldberg, M. A. Wilson, D.O. Joly, M. A. Lehr
2003, Journal of Wildlife Diseases (39) 798-807
We cultured 126 Pasteurella multocida isolates, 92 from water and 34 from sediment samples collected from wetlands in the Pacific and Central flyways of the United States between 1996 and 1999. Most (121) of the isolates were P. multocida serotype 1, but serotypes 3, 3/4, 10, and 11 were also...
Wolf social ecology
L. David Mech, Luigi Boitani
L. David Mech, Luigi Boitani, editor(s)
2003, Book chapter, Wolves: Behavior, ecology and conservation
The first real beginning to our understanding of wolf social ecology came from wolf 2204 on 23 May 1972. State depredation control trapper Lawrence Waino, of Duluth, Minnesota, had caught this female wolf 112 km (67 mi) south of where L. D. Mech had radio-collared her in the Superior National...

Satellite telemetry and wildlife studies in India: Advantages, options and challenges
Sàlim Javed, Hiroyoshi Higuchi, Meenakshi Nagendran, John Y. Takekawa
2003, Current Science (85) 1439-1443
Greater spatial coverage, accuracy and non-invasiveness of satellite technology make it one of the best tools to track long-distance migrants, which is otherwise difficult using conventional radio telemetry. In this article, we review the evolution of satellite telemetry and its application. We provide examples of three recent studies in India...
Environmental fate and effects of the lampricide bayluscide: a review
Verdel K. Dawson
2003, Journal of Great Lakes Research (29 Suppl. 1) 475-492
Bayluscide is an additive to TFM that increases the effectiveness of TFM as a lampricide. A review of the literature was undertaken to determine the environmental fate and effects of Bayluscide. Niclosamide (2', 5-dichloro-4'-nitrosalicylanilide), the active ingredient of Bayluscide, degrades rapidly in natural water and sediment systems, however, the rate...
Biological structure and dynamics of fish assemblages in tributaries of eastern Lake Ontario
James E. McKenna Jr.
M. Munawar, editor(s)
2003, Book chapter, State of Lake Ontario: past, present and future
Interest in effective management of Great Lakes natural resources and restoration of native populations has stimulated interest in the conditions and ecological role of tributaries in the Great Lakes ecosystem. Rivers of Lake Ontario's eastern basin provide an excellent opportunity to examine important tributaries and their relationship to Lake...
The offshore fish community in southern Lake Ontario, 1972-1998
Randall W. Owens, Robert O’Gorman, Thomas H. Eckert, Brian F. Lantry
M. Munawar, editor(s)
2003, Book chapter, State of Lake Ontario: past, present and future
The authors document the status of Lake Ontario's open-water fish community in 1972, near the beginning of an era of massive fish stocking and when phosphorus levels in the lake from anthropogenic inputs, were near their peak. They then describe changes that occurred in the fish community in 1978-98....
Detection of West Nile virus infection in birds in the United States by blocking ELISA and immunohistochemistry
M. Jozan, R. Evans, R. McLean, R. Hall, B. Tangredi, L. Reed, J. Scott
2003, Vector-Borne and Zoonotic Diseases (3) 99-110
A blocking ELISA targeting an immunodominant West Nile epitope on the West Nile Virus NS1 protein was assessed for the detection of West Nile–specific antibodies in blood samples collected from 584 sentinel chickens and 238 wild birds collected in New Jersey from May–December 2000. Ten mallard ducks (Anas platyrhynchos) experimentally...
Sarcocysts of an unidentified species of Sarcocystis in the sea otter (Enhydra lutris)
J. P. Dubey, D. S. Lindsay, B.M. Rosenthal, N. J. Thomas
2003, Journal of Parasitology (89) 397-399
The number of Sarcocystis species that infect sea otters (Enhydra lutris) is unknown. Sea otter tissues were recently shown to harbor sarcocysts of S. neurona and of unidentified species of Sarcocystis. Whereas sarcocysts of S. neurona have walls 1–3 μm thick with type 9 villar protrusions, ultrastructure...
Homerange and movements of boreal toads in undisturbed habitats
E. Muths
2003, Copeia (2003) 160-165
Comparison is made of the population of ospreys in Cape May County, N.J., in the late 1930's with that in 1963, and with a population of these birds at Tilghman Island, Maryland. Production of young per nest in the 1930's compares favorably with the production of young in the populations...
The influence of partial clutch depredation on duckling production
Joshua T. Ackerman, J.M. Eadie, D.L. Loughman, G.S. Yarris, M.R. McLandress
2003, Journal of Wildlife Management (67) 576-587
Nest depredation is the foremost cause of reproductive failure in waterfowl. Management strategies typically have focused on reducing predator contact with nests, yet the late of nests after predators have found them has received little attention. Although nest depredation can result in complete clutch loss, nests often are only partially depredated and the remaining clutch may be successful....
A review of lake trout (Salvelinus namaycush) restoration in Lake Ontario from an early life history perspective
John Fitzsimons, Brian F. Lantry, Robert O’Gorman
M. Munawar, editor(s)
2003, Book chapter, The state of Lake Ontario: past, present and future
The authors conclude that small numbers of lake trout spawned successfully each year during 1992-97 in Lake Ontario, although this has yet to result in a trend of increasing natural reproduction. Juxtaposed with the high abundance of mature fish (Selgeby et al., 1995), the situation in Lake Ontario suggests...
Selection of flooded agricultural fields and other landscapes by female northern pintails wintering in Tulare Basin, California
Joseph P. Fleskes, Robert L. Jarvis, David S. Gilmer
2003, Wildlife Society Bulletin (31) 793-803
Habitat selection and use are measures of relative importance of habitats to wildlife and necessary information for effective wildlife conservation. To measure the relative importance of flooded agricultural fields and other landscapes to northern pintails (Anas acuta) wintering in Tulare Basin (TB), California, we radiotagged female pintails during late August-early...
