Wolf pack spacing: Howling as a territory-independent spacing mechanism in a territorial population Wolf pack spacing: Howling as a territory-independent spacing mechanism in a territorial population
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 pack's location, or the locations of the pack and...

Organochlorine and metal residues in royal terns nesting on the central Texas coast Organochlorine and metal residues in royal terns nesting on the central Texas coast
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 residues did not vary significantly between study areas, and with the...

Distribution of submersed aquatic macrophytes in the tidal Potomac River Distribution of submersed aquatic macrophytes in the tidal Potomac River
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 populations remain in the mesohaline section of the estuary. Present plant...

Osmoregulatory function in ducks following ingestion of the organophosphorus insecticide fenthion Osmoregulatory function in ducks following ingestion of the organophosphorus insecticide fenthion
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 fenthion. Ducks were bled by jugular venipuncture...
