Researcher studies bat hibernation for clues to white-nose syndrome

Tucked in a basement laboratory at Bucknell University, a colony of little brown bats is getting ready to hibernate, and researchers are taking note. The bats will be housed in a simulated cave this winter as part of a several multi-state research projects to learn more about white-nose syndrome, a mysterious condition that is killing bats throughout the northeastern United States. DeeAnn Reeder, an ecophysiologist and assistant professor of biology at Bucknell, will study hibernation patterns in the usually resilient little brown bat, one of the most common bat species in the United States. State and federal officials and other academic researchers are studying different aspects of the syndrome, which gets its name from the white fungus found on many ailing bats.

Abalone test results received so far today (Wednesday, September 17) have not added to the known areas of disease presence in Tasmania. Chief Veterinary Officer, Dr Rod Andrewartha, said that wild samples from the King Island region returned negative results to DNA-testing for Abalone Viral Ganglioneuritis.“Also negative were samples taken from a second southern processor which had reported suspect signs in abalone held on the premises,” Dr Andrewartha said. “The fish tested from this processor came from both the West and East coasts.

Area: Point Pleasant Beach, New Jersey, USA - Map It
Uncounted scores of fish, largely gizzard shad and lake perch, washed up on the shores of Lake of the Lillies in Point Pleasant Beach overnight Wednesday with no apparent cause. The dissolved oxygen level, which is an indicator of a lake's health, was normal around noon Wednesday, said Shawn Crouse, a state Division of Fish and Wildlife freshwater marine biologist. However, oxygen levels fluctuate throughout the day — usually dropping lower at night, Crouse said. "If it stared last night, it was cool and that usually drives oxygen levels up," said L. Stanton Hales Jr., director of the Barnegat Bay National Estuary Program in Toms River. "It could be some nuisance algal bloom; someone could have spilled something. We don't like to think about it, but there are some diseases of fish. Until water and tissue samples are collected and tested, we're just sort of guessing."

Montreal water treatment plants dumping as much as 90 times the critical amount of estrogen products into the river
The Montreal water treatment plant dumps 90 times the critical amount of certain estrogen products into the river. It only takes one nanogram (ng) of steroids per liter of water to disrupt the endocrinal system of fish and decrease their fertility. These are the findings of Liza Viglino, postdoctoral student at the Université de Montréal's Department of Chemistry, at the NSERC Industrial Research Chair in Drinking Water Treatment and Distribution, who is under the supervision of Professors Sébastien Sauvé and Michèle Prévost. The presence and effects of estrogen residues on aquatic wildlife are well documented. However, this research is unique because it didn't only consider natural hormones and those used in oral contraceptives – it also included products used in hormone therapy that is prescribed to menopausal women.
