North American Breeding Bird Survey (BBS) is a cooperative program that monitors the status and trends of North American bird populations. Includes files of results, analyses, route collection maps and raw data.
This updated global inventory reports on natural gas hydrate recovered or inferred from geophysical, geochemical, or geological evidence. Includes links to world location maps, inventories, references and posters. Also in PDF format files.
Identification manual with colored photos of species of puddle ducks, diving ducks, geese, mergansers, swans, cranes, herons, egrets, pelicans and cormorants. Also includes information on ordering print copy and downloading as *.zip file.
Relations between the geographic distributions of woody plant species and climatic variables in North America. Shows how the spatial distribution of these plants may be expected to change in response to given climatic scenarios.
Changes in both the ocean and coastal ecosystems may have negative effects on sea otter populations in the coastal Northwest and Alaska. A study underway will examine these factors and the overall health of sea otter populations.
Background information and genetic sequencing data for more than 1,000 individual field isolates of the fish virus Infectious Hematopoietic Necrosis Virus (IHNV) collected in western North America from 1966 to the present, updated annually.
We estimated undiscovered resources of 1,321 million barrels of oil, 25,386 billion cubic feet of gas, and 604 million barrels of natural gas liquids in this area using a geology based assessment methodology.
Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.
Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.
