Frequency sampling in microhistological studies: An alternative model
B. Kenneth Williams
1987, Journal of Range Management (40) 109-112
Frequency sampling in microhistological studies is discussed in terms of sampling procedures, statistical properties, and biological inferences. Two sampling approaches are described and contrasted, and some standard methods for improving the stability of density estimators are discussed. Possible sources of difficulty are highlighted in terms of sampling design and statistical...
Blastomycosis in wild wolves
Richard P. Thiel, L. David Mech, George R. Ruth, John R. Archer, Leo Kaufman
1987, Journal of Wildlife Diseases (23) 321-323
Blastomycosis was fatal to a wild wolf in Minnesota, and serologic evidence of blastomycosis was found in a Wisconsin wolf. No unusual movements were detected in the Minnesota animal from October 1983 through October 1985. However, by early December 1985, this wolf was weak and debilitated, and it perished on...
Primary molt of California condors
N.F.R. Snyder, E.V. Johnson, D.A. Clendenen
1987, Condor (89) 468-485
Primary molt of the California Condor (Gymnogyps californianus) was studied intensively from 1982 through 1985, using repeated flight photographs of the remaining individuals in the wild population as a basis for most analyses. On the average, wild condors replaced 4.4 of the 8 emarginated primaries on each wing each year....
Some aspects of the breeding biology of the snail kite in Florida
P.W. Sykes Jr.
1987, Journal of Field Ornithology (58) 171-189
The breeding biology of the Snail Kite was studied in Florida from 1968-1977 and intermittently from 1978-1980. Breeding occurred every month, but not in the same year. Peak egg-laying occurred from February through April or generally about 8 1 d before the onset of the rainy season in mid- or...
Relationship of deer and moose populations to previous winters' snow
L.D. Mech, R.E. McRoberts, R. O. Peterson, R.E. Page
1987, Journal of Animal Ecology (56) 615-627
(1) Linear regression was used to relate snow accumulation during single and consecutive winters with white-tailed deer (Odocoileus virginianus) fawn:doe ratios, moose (Alces alces) twinning rates and calf:cow ratios, and annual changes in deer and moose populations. Significant relationships were found between snow accumulation during individual winters and these dependent...
Ecology, behavior, and conservation of the Maui parrotbill
Stephen Mountainspring
1987, Condor (89) 24-39
The distribution, habitat response, sexual dimorphism, foraging, breeding, and flocking behavior of Maui Parrotbills (Pseudonestor xanthophrys ) were studied over a five year period. The species' present range is confined to montane rainforest on eastern Maui, but dry lowland habitats on Maui and Molokai were occupied before Polynesian contact. Birds...
Release of captive-reared or translocated endangered birds: What do we need to know?
J. Michael Scott, J. W. Carpenter
1987, The Auk (104) 544-545
Attempts to evaluate the success of endangered-species reintroduction programs are frustrated by a lack of reliable information on releases of either endangered or nonendangered species. Although many programs have attempted to establish or augment wild populations with captive-reared or wild-caught birds (Williams 1977), there are few published accounts that allow...
