www.pwrc.usgs.gov — Dr. Howard Ginsberg is studying the transmission of Lyme disease spirochetes in nature using ecological studies of ticks and their vertebrate hosts, and models of spirochete transmission dynamics. Environmental factors that influence tick populations apparently operate on a regional scale. Distribution of vertebrate hosts plays a role in tick More...

www.nrmsc.usgs.gov — Every winter, government agencies feed ;6000 metric tons (63 106 kg) of hay to elk in the southern Greater Yellowstone Ecosystem (GYE) to limit transmission of Brucella abortus, the causative agent of brucellosis, from elk to cattle. Supplemental feeding, however, is likely to increase the transmission of brucellosis in elk, and may be affected by More...

www.usgs.gov — It has been estimated that over 100,000 bats have died in the northeast due to a mysterious white fungus called White-Nose Syndrome (WNS). Scientists are finding within caves and mines a large number of bats with a white fungus on their muzzles and other parts of their bodies. It is uncertain as to how this fungus is being transmitted and its More...

www.fws.gov — Tens of thousands of hibernating bats died this winter in the northeast, and for unknown reasons. In and around caves and mines in eastern and upstate New York, Vermont, western Massachusetts, and northwestern Connecticut, biologists found sick, dying and dead bats in unprecedented numbers. In just eight of the affected New York caves, mortality More...

www.fort.usgs.gov — During the winter of 2006 or 2007, an affliction of unknown origin dubbed "White-Nose Syndrome" (WNS) began devastating colonies of hibernating bats in a small area around Albany, New York. Colonies of hibernating bats were reduced 81-97 percent at the affected caves and mines that were surveyed. Since then, White-Nose Syndrome has been detected More...
