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...
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...
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....
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...
Biogeochemical cycling of selenium in the San Joaquin Valley, California, USA
T. S. Presser, H. M. Ohlendorf
1987, Environmental Management (11) 805-821
Subsurface agricultural drainage waters from western San Joaquin Valley, California, were found to contain elevated concentrations of the element selenium in the form of selenate. In 1978, these drainage waters began to replace previous input to Kesterson Reservoir, a pond system within Kesterson National Wildlife Refuge; this substitution was completed...
The use of analysis of variance procedures in biological studies
B. Kenneth Williams
1987, Applied Stochastic Models and Data Analysis (3) 207-226
The analysis of variance (ANOVA) is widely used in biological studies, yet there remains considerable confusion among researchers about the interpretation of hypotheses being tested. Ambiguities arise when statistical designs are unbalanced, and in particular when not all combinations of design factors are represented in the data. This paper clarifies...
Analysis of survival data from telemetry projects
C.M. Bunck
1987, Journal of Raptor Research (21) 132-134
Telemetry is an increasingly popular method for studying animal movements and habitat use. Telemetry provides a means for studying survival and causes of mortality. This paper describes some statistical techniques which can provide valid estimates of survival rates based on data from telemetry studies....
