The name of Lawrence's flycatcher The name of Lawrence's flycatcher
If Lawrence's flycatcher of Grenada, Trinidad, and northern South America is placed in the genus Lathrotriccus with the species euleri, it should be L. flaviventris (Lawrence) or L. euleriflaviventris, depending on rank. If it remains in the genus Empidonax, the specific name should be bolivianus Allen.

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...

A science-based, watershed strategy to support effective remediation of abandoned mine lands A science-based, watershed strategy to support effective remediation of abandoned mine lands
A U.S. Geological Survey Abandoned Mine Lands Initiative will develop a strategy for gathering and communicating the scientific information needed to formulate effective and cost-efficient remediation of abandoned mine lands. A watershed approach will identify, characterize, and remediate contaminated sites that have the most profound effect on water and ecosystem quality within a...

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

The first nest records of the sooty antbird (Myrmeciza fortis) with notes on eggs and nestling development The first nest records of the sooty antbird (Myrmeciza fortis) with notes on eggs and nestling development
Two Myrmeciza fortis nests were discovered in a lowland floodplain forest of Manu National Park, Peru. Both nests were embedded in leaf litter on the ground and were oven-shaped with a an entrance and an inner chamber concealing two eggs. Unlike the known nests of other Myrmeciza spp., the nests of Myrmeciza fortis closely resembled nests of other species in the Thamnophilidae. This...

Evaluation of a mallard HSI model for the Lower Mississippi Valley Evaluation of a mallard HSI model for the Lower Mississippi Valley
We evaluated a habitat suitability (HSI) model developed for mallards (Anas platyrhynchos) wintering in the Lower Mississippi Valley by comparing mallard densities obtained from aerial surveys with habitat suitability indices derived from satellite imagery for 25, 256km2 sampling units. Regression models that related mallard densities to habitat suitability indices accounted for only 29%...
