This is an issue of great concern, as these populations are already struggling to survive in the current environment. If some of these species are more vulnerable to fatal WNV infection, WNV may ultimately lead to their extinction or significantly set...
Certain populations of sockeye salmon, coho salmon, chinook salmon, and Atlantic salmon are listed as endangered. Sockeye salmon from the Snake River system are probably the most endangered salmon. Coho salmon in the lower Columbia River may already be...
Bats are among the world's least appreciated and most endangered animals.A good starting point for information on bats is USGS Northern Prairie Wildlife Research Center's pages on bats.  The web page includes links to other sources of information. You...
Whether you live in a house, condominium, or apartment, there are several things you can do to decrease the potential for snakes to enter your living space.  Excluding snakes from buildings depends on closing or eliminating the most minute openings...
As a rear-fanged snake from the family of Colubrid snakes, brown Treesnakes are often classified as non-venomous.  However, as snakes on Guam (with the abundantly available food) have grown to longer lengths than what is found in their native range, some...
