Estimating taxonomic diversity, extinction rates, and speciation rates from fossil data using capture-recapture models
J.D. Nichols, K. H. Pollock
1983, Paleobiology (9) 150-163
Methods currently used to estimate taxonomic extinction probabilities from fossil data generally assume that the probability of encountering a specimen in a particular stratum, given that the taxon was extant in the time period and location represented by the stratum, either equals 1.0 or else is a constant for all...
Impacts of forest herbicides on wildlife: Toxicity and habitat alteration
M.L. Morrison, E. Charles Meslow
1983, Transactions of the North American Wildlife and Natural Resources Conference (48) 175-185
This paper begins with a review of both laboratory and field studies on tbe possible direct toxic effects of herbicides on terrestrial vertebrates, primarily birds and mammals. Alteration of the palatability of forage and changes in reproductive success are also discussed. Emphasis is placed on the use of...

Residues of petroleum hydrocarbons in tissues of sea turtles exposed to the IXTOC I oil spill
R.J. Hall, A. A. Belisle, L. Sileo
1983, Journal of Wildlife Diseases (19) 106-109
Sea turtles found dead when the Ixtoc I oil spill reached Texas waters were necropsied and tissues were analyzed for residues of petroleum hydrocarbons. Two of the three turtles were in poor flesh, but had no apparent oil-caused lesions. There was evidence of...
Wolf pack spacing: Howling as a territory-independent spacing mechanism in a territorial population
F.H. Harrington, L.D. Mech
1983, Behavioral Ecology and Sociobiology (12) 161-168
Howling is a principle means of spacing in wolf populations. The relationship between a pack's responses to howling (replies, movements) and its location within its home range, was studied using human-simulated howling in a territorial population in northeastern Minnesota. The results indicated the responses were independent of the...
Response of American black ducks to dietary uranium: A proposed substitute for lead shot
Susan D. Haseltine, Louis Sileo
1983, Journal of Wildlife Management (47) 1124-1129
Lead (Pb) shot has been associated with mortality in waterfowl (Trainer and Hunt 1965, Anderson 1975, Stout and Cornwell 1976) and other avian species (Benson et al. 1974, Kaiser et al. 1980, Pattee et al. 1981). Bellrose (1959) indicated that between 2 and 3% of waterfowl populations may be lost...
Organochlorine and metal residues in royal terns nesting on the central Texas coast
Kirk A. King, C.A. LeFever, B.M. Mulhern
1983, Journal of Field Ornithology (54) 295-303
Royal Tern eggs collected from Pelican and Sundown islands on the central Texas coast in 1978 contained relatively low levels of organochlorine and metal pollutants. DDE and PCBs were found most frequently, but levels were below those known to have an adverse effect on avian reproduction and survival. Average metal...

Distribution of submersed aquatic macrophytes in the tidal Potomac River
G.M. Haramis, V. Carter
1983, Aquatic Botany (15) 65-79
Results of a 3-year survey (1978?1980) and review of historic trends have shown a major decline in the number of species and the distribution of submersed aquatic macrophytes in the tidal Potomac River since the early 1900's. The freshwater tidal river is essentially devoid of plants and only very sparse...
Pack size and wolf pup survival: their relationship under varying ecological conditions
Fred H. Harrington, L. David Mech, Steven H. Fritts
1983, Behavioral Ecology and Sociobiology (13) 19-26
The relationship between pack size and two parameters of reproductive success (litter size at 7–8 months and pup weights at 5–6 months) were determined for two wolf (Canis lupus) populations in northern Minnesota. Pup weights were not correlated with pack size for either population. Litter size, however,...
Altered avoidance behavior of young black ducks fed cadmium
G. H. Heinz, S. D. Haseltine, L. Sileo
1983, Environmental Toxicology and Chemistry (2) 419-421
Pairs of adult black ducks (Anas rubripes) were fed a diet containing 0, 4 or 40 ppm cadmium as cadmium chloride. One-week-old ducklings that had been fed the same dietary concentrations of cadmium as had their parents were tested for avoidance of a fright stimulus. Ducklings fed 4 ppm cadmium...

Seasonal energetics and behavior of captive canvasbacks (Aythia valisineria)
Matthew C. Perry, Wayne J. Kuenzel
1983, Poultry Science (62) 1482 (abstract)
Dramatic changes in the food habits and distribution of Chesapeake Bay canvasbacks (Aythya valisineria) generated a desire to better understand the energetics and behavior of this species on its wintering grounds. Captive canvasbacks were maintained ad libitum on 5 diets during the winters of 1978-80 to evaluate varying protein...
Oxychlordane, HCS-3260, and nonachlor in birds: Lethal residues and loss rates
L.F. Stickel, W. H. Stickel, R. A. Dyrland, D.L. Hughes
1983, Journal of Toxicology and Environmental Health (12) 611-622
Oxychlordane reached lethal levels in birds given dietary dosages of HCS-3260 (70.75% cis-chlordane and 23.51% trans-chlordane) at 6 levels from 50 to 500 ppm. Oxychlordane ranged from 9.4 to 22.1 ppm in brains of cowbirds (Molothrus ater ) grackles (Quiscalus quiscula , and red-winged blackbirds (Agelaius phoeniceus ) that...
Osmoregulatory function in ducks following ingestion of the organophosphorus insecticide fenthion
Barnett A. Rattner, W. James Fleming, H. C. Murray
1983, Pesticide Biochemistry and Physiology (20) 246-255
Salt gland function and osmoregulation in aquatic birds drinking hyperosmotic water has been suggested to be impaired by organophosphorus insecticides. To test this hypothesis, adult black ducks (Anas rubripes) were provided various regimens of fresh or salt (1.5% NaCl) water before, during, and after ingestion of mash containing 21 ppm...

Many of the known recoverable coal reserves in the Western United States occur within the breeding and wintering range of the Brewer's sparrow. Although the species is common throughout much of its breeding range, local and regional populations may be adversely affected due to mining-related disturbances and habitat loss. The...
