Late winter survival of female mallards in Arkansas Late winter survival of female mallards in Arkansas
Determining factors that limit winter survival of waterfowl is necessary to develop effective management plans. We radiomarked immature and adult female mallards (Anas platyrhynchos) after the 1988 and 1989 hunting seasons in eastcentral Arkansas to test whether natural mortality sources and habitat conditions during late winter limit seasonal survival. We used data from 92 females to...

Falkner Island, a two hectare unit of the Stewart B. McKinney National Wildlife Refuge, is located at 41°13'N, 72°39'W in Long Island Sound about 5 km south of Guilford, Connecticut. This island, described in detail by Helander (1988), is the nesting site of a mixed colony of several thousand Common Terns (Sterna hirundo) and a few hundred Roseate Terns (S. dougallii) (Spendelow 1994a,b)...

Keys to a successful project: Associated data and planning: Data standards Keys to a successful project: Associated data and planning: Data standards
The many individual salamanders, frogs, caecilians, and their larvae encountered during the course of an inventory or monitoring project will have to be identified to species. Depending on the goals and sampling method(s) used, some individuals will be identified from a distance by their calls, others will be handled. At the same time, some will be marked for recapture, and others will...

Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela
The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted local distribution and habitat use for 40 species of diurnal...

Relation among cytochrome P450, AH-active PCB congeners and dioxin equivalents in pipping black-crowned night-heron embryos Relation among cytochrome P450, AH-active PCB congeners and dioxin equivalents in pipping black-crowned night-heron embryos
Pipping black-crowned night-heron (Nycticorax nycticorax) embryos were collected from a relatively uncontaminated site (next to Chincoteague National Wildlife Refuge, VA) and three polluted sites (Cat Island, Green Bay, Lake Michigan, WI; Bair Island, San Francisco Bay, CA; West Marin Island, San Francisco Bay, CA). Hepatic cytochrome P-450-associated monooxygenases and cytochrome P-450...

Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals
Elevated levels of cadmium in Pacific walrus (Odobenus rosmarus divergens) and northern fur seals (Callorhinus ursinus) have been reported in populations from the Bering Sea (Goldblatt & Anthony, 1983; Taylor et al., 1989). Russian and US authorities are concerned because of the possible health hazards from consuming pinniped meat harvested for subsistence peoples. The effects of cadmium...
