Waterfowl and wetlands management in the coastal zone of the Atlantic Flyway: Meeting and summary comments Waterfowl and wetlands management in the coastal zone of the Atlantic Flyway: Meeting and summary comments

A conference on waterfowl and wetlands along the Atlantic coast of North America was held in Wilmington, Delaware in September 1986. Discussions centered around coastal impoundments and Open Marsh Water Management as methods of mosquito control and waterfowl enhancement. Single purpose management of coastal marshes, whether for mosquito control or waterfowl, may not be the most...

Cholinesterase inhibition in meadow voles (Microtus Pennsylvanicus) following field applications of orthene® Cholinesterase inhibition in meadow voles (Microtus Pennsylvanicus) following field applications of orthene®

Brain acetylcholinesterase activity in field-caught meadow voles (Microtus pennsylvanicus) was depressed after a field-spray of Orthene® (acephate: acetylphosphoramidothioic acid O,S-dimethyl ester) by as much as 32% in 1982 and 38% in 1983. Short-term recovery was demonstrated and occurred in a time-dependent fashion in 1982. Plasma Cholinesterase levels were more variable but also were...

The relationship between body mass and survival of wintering canvasbacks The relationship between body mass and survival of wintering canvasbacks

Mass and recapture histories of 6,000 Canvasbacks (Aythya valisineria) banded in upper Chesapeake Bay were used to test two hypotheses: (1) early-winter body mass is associated with the probability of surviving the winter, and (2) early-winter body mass is associated with annual survival probability. Data were analyzed by a binary regression method that treated mass as a continuous...

Chemical scent constituents in urine of wolf (Canis lupus) and their dependence on reproductive hormones Chemical scent constituents in urine of wolf (Canis lupus) and their dependence on reproductive hormones

The volatile components of castrated male and ovariectomized female wolf urine were investigated and correlated with the administration of testosterone or estradiol and progesterone. The results indicate that testosterone induces in the castrated male the formation of some compounds typically associated with the intact male, while reducing the levels of some compounds associated with...

An overview of raptor conservation in Latin America An overview of raptor conservation in Latin America

Prior to the last decade, biological studies of raptorial birds in Latin America were almost nonexistent. For many species little more was known than their general range and habitat type. The last few years have seen the opening of a door to what will surely be a flood of scientific investigations. Ultimately, the survival of raptor communities in Latin America depends not only on...

Association between PCBs and lower embryonic weight in black-crowned night herons in San Francisco Bay Association between PCBs and lower embryonic weight in black-crowned night herons in San Francisco Bay

Reproductive problems, including congenital malformations, reduced hatching success, and decreased survival of hatchlings, have been observed in colonial-nesting water birds at the San Francisco Bay National Wildlife Refuge (SFBNWR). Twenty-four black-crowned night heron (Nycticorax nycticorax) eggs were collected from SFBNWR in 1983. Twelve of these were collected from separate nests...
