Population trends and environmental contaminants in herons in the Tennessee Valley, 1980-81
W. James Fleming, B.P. Pullin, D. M. Swineford
1984, Colonial Waterbirds (7) 63-73
Great Blue Heron (Ardea herodias) eggs (N = 40) collected in 1980 from four of the largest colonies in the Tennessee Valley contained organochlorine pesticide, polychlorinated biphenyl (PCB), and chromium concentrations below those associated with reduced productivity. Low concentrations of organochlorine pesticide and PCB residues also were found in...
Tissue lead distribution and hematologic effects in American kestrels (Falco sparverius) fed biologically incorporated lead
T. W. Custer, J. C. Franson, O. H. Pattee
1984, Journal of Wildlife Diseases (20) 39-43
American kestrels were fed a diet containing 0.5, 120, 212, and 448 ppm (dry wt) biologically incorporated lead (Pb) for 60 days. The diet consisted of homogenized 4-wk-old cockerels raised on feed mixed with and without lead. No kestrels died and weights did not differ among treatment groups. The control...

Disseminated visceral coccidiosis in sandhill cranes

1984, Journal of the American Veterinary Medical Association (185) 1343-1346
Disseminated visceral coccidiosis (DVC) caused by Eimeria spp was first recognized as a disease entity in captive sandhill cranes (Grus canadensis) and whooping cranes (G americana) at the Patuxent Wildlife Research Center. Because cranes produced at the Center are reintroduced to the wild to augment wild populations, studies involving both...

Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results
M.J. Conroy, J.D. Nichols
1984, Paleobiology (10) 328-337
Several important questions in evolutionary biology and paleobiology involve sources of variation in extinction rates. In all cases of which we are aware, extinction rates have been estimated from data in which the probability that an observation (e.g., a fossil taxon) will occur is related both to extinction rates and...

Acute responses of American kestrels to methyl parathion and fenvalerate
Barnett A. Rattner, J. C. Franson
1984, Federation Proceedings (43)
Physiological and toxicological effects of p.o, methyl parathion (0.375-3.0 mg/kg) or fenvalerate (1000-4000 mg/kg) were examined over a 10 h period in American kestrels (Falco sparverius) maintained in thermoneutral (22?.C) and cold (-5?.C) environments. Methyl parathion was highly toxic (LD50=3.08 mg/kg, 95% confidence limits=2.29-4.l4 mg/kg, producing overt intoxication (abnormal posture,...

Simulation analyses of space use: Home range estimates, variability, and sample size
Marc Bekoff, L. David Mech
1984, Behavior Research Methods, Instruments, and Computers (16) 32-37
Simulations of space use by animals were run to determine the relationship among home range area estimates, variability, and sample size (number of locations). As sample size increased, home range size increased asymptotically, whereas variability decreased among mean home range area estimates generated by multiple simulations for the same sample...

Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area

1984, Environmental Monitoring and Assessment (4) 129-137
Moths were collected with a light trap from 15 sites in the Baltimore, Maryland-Washington, D.C. area and analyzed for organochlorine pesticide residues. On the average, the species sampled contained 0.33 ppm heptachlor-chlordane compounds, 0.25 ppm DDE, and 0.11 ppm dieldrin. There were large differences in the concentrations detected in different...
