Modeling metapopulation dynamics for single species of seabirds
P. A. Buckley, R. Downer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations
Seabirds share many characteristics setting them apart from other birds. Importantly, they breed more or less obligatorily in local clusters of colonies that can move regularly from site to site, and they routinely exchange breeders. The properties of such metapopulations have only recently begun to be examined, often with...
The swan neck band protocol--time for revision
J. Tautin
Carl D. Mitchell, Janissa Balcomb, John E. Cornely, editor(s)
1992, Book chapter, Proceedings and Papers of the Thirteenth Trumpeter Swan Society Conference, 13-16 February, 1991, Salt Lake City, Utah
Metabolic products as biomarkers
M. J. Melancon, R. Alscher, W. Benson, G. Kruzynski, R.F. Lee, H.C. Sikka, R.B. Spies
Robert J. Huggett, Richard A. Kimerle, Paul M.= Mehrle Jr., Harold L. Bergman, editor(s)
1992, Book chapter, Biomarkers: Biochemical, Physiological, and Histological Markers of Anthropogenic Stress.
Ideally, endogenous biomarkers would indicate both exposure and environmental effects of toxic chemicals; however, such comprehensive biochemical and physiological indices are currently being developed and, at the present time, are unavailable for use in environmental monitoring programs. Continued work is required to validate the use of biochemical and physiological...
A warbler in trouble: Dendroica cerulea
C.S. Robbins, J.W. Fitzpatrick, P.B. Hamel
John M. Hagan III, David W. Johnston, editor(s)
1992, Book chapter, Ecology and Conservation of Neotropical Migrant Landbirds
The Cerulean Warbler, like other Neotropical migrants, has suffered extensive loss of breeding habitat during the past century. It differs from many other migrants in its preference for mature floodplain forest with tall trees, a habitat that has become scarce over much of the warbler's original nesting range. Sensitivity to...
Techniques for rearing and releasing nonmigratory cranes: Lessons from the Mississippi Sandhill Crane program
D. H. Ellis, Glenn H. Olsen, G.F. Gee, Jane M. Nicolich, K.E. O’Malley, Meenakshi Nagendran, Scott G. Hereford, P. Range, W.T. Harper, R.P. Ingram, D.G. Smith
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop.
Captive-reared Mississippi sandhill cranes (Grus canadensis pulla) reared at the Patuxent Wildlife Research Center (Patuxent) have been released at the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) since 1981. Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989...
Relating results from earthworm toxicity tests to agricultural soil
W. N. Beyer
P.W. Greig-Smith, editor(s)
1992, Book chapter, Ecotoxicology of Earthworms
The artificial soil tests of the European Economic Community and of the Organization for Economic Cooperation produce data relating earthworm mortality to pesticide concentrations in soil under laboratory conditions. To apply these results to agricultural soils it is necessary to relate these concentrations to amounts of pesticide applied per area....
Physiological and nonspecific biomarkers
F.L. Mayer, D.J. Versteeg, M.J. McKee, L.C. Folmar, R.L. Graney, D.C. McCume, Barnett A. Rattner
Robert J. Huggett, Richard A. Kimerle, Paul M.= Mehrle Jr., Harold L. Bergman, editor(s)
1992, Book chapter, Biomarkers: Biochemical, Physiological, and Histological Markers of Anthropogenic Stress
Geographic patterns in population trends of neotropical migrants in North America
J.R. Sauer, Sam Droege
John M. Hagan III, D.W. Johnston, editor(s)
1992, Book chapter, Ecology and Conservation of Neotropical Migrant Landbirds
We use the route-regression method to estimate the population trends of 100 species of Neotropical migrants using data from the North American Breeding Bird Survey (BBS). We examine long-term (1966-1988) and recent (1978-1988) trends. In the long-term, more species of Neotropical migrants were increasing than were decreasing in...
Population recovery of the Whooping Crane with emphasis on reintroduction efforts: Past and future
D. H. Ellis, J. C. Lewis, G.F. Gee, D.G. Smith
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop.
The U.S. Fish and Wildlife Service (USFWS) began building a captive whooping crane (Grus americana) colony at Patuxent Wildlife Research Center (Patuxent), Maryland, in 1966. From 1976 to 1984, 73 eggs from this colony and 216 eggs from Wood Buffalo National Park (Wood Buffalo), Canada, nests were placed in sandhill...
Progress in satellite tracking cranes
D. H. Ellis, D.G. Smith, Glenn H. Olsen, M.R. Fuller, S.E. Landfried, H. Higuchi, C.H. Vermillion
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop
We review the history of tracking cranes with satellite telemetry and identify some of the difficulties in designing satellite transmitters and harnesses for cranes. Miniaturization of these transmitters and a plethora of harnessing experiments since 1989 allow us to recommend limited application of this technology to all species of cranes....
Behavior of sandhill cranes harnessed with different satellite transmitters
Glenn H. Olsen, D. H. Ellis, S.E. Landfried, L.H. Miller, S.S. Klugman, M.R. Fuller, C.H. Vermillion
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop
The effectiveness of various attachment methods and designs of platform transmitting terminals (PTT's) was tested on captive sandhill cranes (Grus canadensis) at the Patuxent Wildlife Research Center, Laurel, Maryland, during 1989-91. Combinations of attachment and transmitter designs included neoprene cord harness with batteries separate from the transmitter (2 harness designs),...
The study of relatedness and genetic diversity in cranes
G.F. Gee, H.C. Dessauer, J. Longmire, W.E. Briles, R.C. Simon
Don A. Wood, editor(s)
1992, Book chapter, Proceedings of the 1988 North American Crane Workshop
The U.S. Fish and Wildlife Service (Service) is responsible for recovery of endangered species in the wild and, when necessary, maintenance in captivity. These programs provide an immediate measure of insurance against extinction. A prerequisite inherent in all of these programs is the preservation of enough genetic diversity to maintain...
