Toxicity of methyl parathion to bats: Mortality and coordination loss Toxicity of methyl parathion to bats: Mortality and coordination loss
The 24-h oral LD50 of methyl parathion (phosphorothioic acid O, O-dimethyl O-(4-nitrophenyl) ester) to little brown bats (Myotis lucifugus) (372 mg/kg) was 8.5 times the LD50 for mice (Mus musculus) (44 mg/kg). However, orally dosed mice either died or appeared behaviorally normal after 2 to 3 h, whereas many dosed bats, although alive at 24 h, could not right themselves when placed 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...

Frozen gene pools - A future for species otherwise destined for extinction Frozen gene pools - A future for species otherwise destined for extinction
Conclusion: Semen banks and ova and embryo banks can be practical methods to maintain gene pools. Gene pool preservation is desperately needed today due to the rapid decline in number of species and their habitat, a matter that is of concern to.biologists, economists, and politicians worldwide. Techniques are available for the cryopreservation of semen from many animals (and embryos from...

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...

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...
