Fluorspar Fluorspar
Developments in the area of fluorspar in 1996 are reviewed. There was no reported mine production of fluorspar the U.S. in 1996, so domestic fluorspar requirements were satisfied by imports, sales from the National Defense Stockpile, and small amounts of synthetic fluorspar produced from industrial waste. The Defence Logistics Agency, consumption, imports, exports, markets, production of...

Creation, management, and research on lakes and ponds at Patuxent Research Refuge Creation, management, and research on lakes and ponds at Patuxent Research Refuge
From 19391966, approximately 450 acres of impoundments were created for recreational and wildlife conservation purposes at Patuxent Research Refuge. Impoundments were of three major designs: impounded ravines, excavated basins, and impounded swamps. Over 50 species of wetland plants were transplanted to impoundments of Patuxent to determine best species for relatively infertile waters...

Zinc hazards to plants and animals with emphasis on fishery and wildlife resources Zinc hazards to plants and animals with emphasis on fishery and wildlife resources
Ecological and toxicological aspects of zinc in the environment are reviewed with emphasis on natural resources. Subtopics include sources and uses; chemical and biochemical properties; carcinogenicity, mutagenicity, teratogenicity; background concentrations in biological and nonbiological compartments; effects of zinc deficiency; toxic and sublethal effects on terrestrial plants and...

Roadblocks on the kill curve: Testing the Raup hypothesis Roadblocks on the kill curve: Testing the Raup hypothesis
The documented presence of two large (~100-km diameter), possibly coeval impact craters of late Eocene age, requires modification of the impact-kill curve proposed by David M. Raup. Though the estimated meteorite size for each crater alone is large enough to have produced considerable global environmental stress, no horizons of mass mortality or pulsed extinction are known to be...

Conservation of Mexican wetlands: role of the North American Wetlands Conservation Act Conservation of Mexican wetlands: role of the North American Wetlands Conservation Act
Mexico's wetlands support a tremendous biological diversity and provide significant natural resource benefits to local communities. Because they are also critical stopover and wintering grounds for much of North America's waterfowl and other migratory birds, Mexico has become an important participant in continental efforts to conserve these resources through the North American Wetlands
