www.batcon.org — Hibernating bats are dying by the tens of thousands in the northeastern United States, and a growing circle of top scientists is anxiously trying to figure out why. The mystery affliction, reported in New York, Vermont and Massachusetts, is dubbed "white-nose syndrome" because many affected bats had visible halos of white fungus around their 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.werc.usgs.gov — Salvage of injured, recently dead, ill, and dying desert tortoises is a very important part of recovery programs for these reptiles. Salvaged desert tortoises can provide a wealth of information about such subjects as health, disease, presence of heavy metals and other toxicants, and causes of mortality in populations. When tortoises are salvaged 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...

wfrc.usgs.gov — Anadromous salmonids are susceptible to a variety of pathogenic microorganisms, including at least 30 bacteria and viruses. Whereas the impact of these microorganisms on salmonids in wild and natural rearing areas is difficult to measure, losses from disease among hatchery salmonids are both common and well documented. The immunology laboratory More...

wfrc.usgs.gov — Viral infections are common causes of disease outbreaks and mortalities in both wild and captive fish populations. Due to the long history of virus outbreaks there is a substantial body of knowledge about viruses within the field of fish pathology. This project involves research and development studies which create, modify and apply modern 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...
