Sleeping distance in wild wolf packs
S.T. Knick, L.D. Mech
1980, Behavioral and Neural Biology (28) 507-511
Sleeping distances were observed among members of 13 wild wolf (Canis lupus) packs and 11 pairs in northeastern Minnesota to determine if the distances correlated with pack size and composition. The study utilized aerial radio-tracking and observation during winter. Pack size and number of adults per pack were...

R.E. Kirby, H.H. Obrecht III
1980, Wildfowl (31) 158-160
Atlantic Brant Branta bernicla hrota in Barnegat Bay, New Jersey, have established a commensal feeding relationship with man. Small flocks feed 3-5 m from clam fishermen on Zostera torn from the sea bottom by the fishing activities. Background material on the availability and digestibility of different brant foods is presented....

1980, Pesticides Monitoring Journal (13) 145-149
During 1975-77, 168 bald eagles (Haliaeetus leucocephalus) found moribund or dead in 29 states were analyzed for organochlorine pesticides and polychlorinated biphenyls (PCBs); 32 specimens from 13 states were analyzed for polybrominated biphenyls (PBBs). PCBs were present in 166 bald eagle carcasses and DDE was found in 165. TDE and...
White-faced ibis populations and pollutants in Texas, 1969-1976
Kirk A. King, D. L. Meeker, D. M. Swineford
1980, Southwestern Naturalist (25) 225-240
Eggshell thickness, levels of pollutant residues, and population status of the white-faced ibis (Plegadis chihi) were monitored in Texas from 1969 through 1976. Texas ibis nesting populations declined by 42%. Reproductive success apparently was limited by DDE-induced shell thinning and by dieldrin-caused mortality. Eggshells averaged 4% to 10% thinner than...

Toxic effects of endrin and toxaphene on the southern leopard frog Rana sphenocephala
R.J. Hall, D. Swineford
1980, Environmental Pollution (Series A) (23) 53-65
Eggs, larvae and sub-adults of the southern leopard frog Rana sphenocephala were exposed to endrin and toxaphene. Exposure was in water by a continuous-flow technique, following standards that have been used successfully in the study of fish and invertebrates. R. sphenocephala is more sensitive to both pesticides than are higher vertebrates but is slightly...
Canine tooth wear in captive little brown bats
Donald R. Clark Jr.
1980, Acta Theriologica (25) 270-273
Upper canine teeth of little brown bats Myotis lucifugus lucifugus held in stainless steel wire mesh cages underwent severe wear which exceeded that observed previously in caged big brown bats, Eptesicus fuscus fuscus. This suggests a relationship between amount of wear and size of the caged bats with damage increasing...
Intestinal absorption of 5 chromium compounds in young black ducks (Anas rubripes)
W. C. Eastin Jr., S. D. Haseltine, H. C. Murray
1980, Toxicology Letters (6) 193-197
An in vivo intestinal perfusion technique was used to measure the absorption rates of five Cr compounds in black ducks. Cr was absorbed from saline solutions of KCr(SO4)2 and CrO3 at a rate about 1.5 to 2.0 times greater than from solutions of Cr, Cr(NO3)3, and Cr(C5H7O2)3. These results suggest the ionic...
Situation report: Heavy DDT contamination at Wheeler National Wildlife Refuge
W. James Fleming, T.Z. Atkeson
1980, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (34) 453-461
A DDT manufacturing plant that operated on the Redstone Arsenal near Huntsville, Alabama discharged DDT-Iaden effluent from 1947 to 1970 into a creek on Wheeler National Wildlife Refuge. Seven to 9 years after the plant closed, high DDT, DDE, and DDD levels were reported in soils, river sediments, and fish...

Lead residues in eastern tent caterpillars (Malacosoma americanum) and their host plant (Prunus serotina) close to a major highway
W. N. Beyer, John Moore
1980, Environmental Entomology (9) 10-12
Eastern tent caterpillars, Malacosoma americanum (F.) (Lepidoptera: Lasiocampidae), and leaves of their host plant, black cherry, Prunus serotina Ehrh., were collected in May, 1978, at various distances from the Baltimore-Washington Parkway, Prince George's Co., MD, and were analyzed for lead by atomic absorption spectrophotometry. Caterpillars collected within 10 m of the parkway contained 7.1–7.4...

The American Ornithologists' Union and its members had an early history of involvement in public affairs and conservation activities. A very active Committee on Bird Protection was among the first of the service committees to be established. In the 1880s it gathered data on the plumage trade and worked...
Waterfowl production estimates on forested wetlands from pair and brood counts
R.E. Kirby
1980, Wildlife Society Bulletin (8) 273-278
Waterfowl pair and brood counts and estimates of total brood utilization were obtained from 10 beaver (Castor canadensis) flowages in north-central Minnesota and compared with rank correlation techniques. Summing the data for each species, correlation between pair and brood censuses was significant ( p = 0.8304, P < 0.025). Similarly,...
