Virus ruled out in fish die-off smelt litter shore

Tests have indicated there were no bacterial or viral infections associated with a massive die-off of rainbow smelt in Lake Erie that covered the shoreline from Point Pelee to south of Simcoe with hundreds of thousands of dead fish.

"The lab results didn't really tell us anything we didn't already know," Andy Cook, assessment biologist for the Ministry of Natural Resources, said Tuesday.

A combination of stormy weather during spawning, fish overpopulation and lower body weight are primary causes that lead to massive piles of dead fish floating on shorelines in late May throughout the lake -- including the U.S. side in Ohio and New York.

Ecology: Emergency medicine for frogs

With chytrid fungus rapidly spreading around the world, researchers are testing an extreme approach to saving endangered amphibian populations.

. . . When Bosch's team evacuated the Mallorcan tadpoles last summer, its goal was to completely eradicate the fungus, which gained a foothold on the island about 20 years ago when frogs were imported to help boost a native species.

"Only four populations are infected, which is why we need to take action very quickly on the island," says Bosch.

Snake Populations Mysteriously Plummet

The world's snakes may be in trouble. New research shows that snake numbers have plummeted in a number of populations worldwide.

"Of 17 populations of snakes covering 11 species, 11 populations had declined. That covered eight species," said study lead author Christopher Reading of the Center for Ecology and Hydrology in Wallingford, U.K.

"They hadn't just declined, they had declined drastically and in exactly the same time and in the same way."

Northern waterfowl could be sitting ducks in gulf disaster

In two months, blue-winged teal will begin leaving Minnesota for the coastal marshes of Louisiana and other points south.

Within weeks afterward, wood ducks will join the autumn migration, followed by many of the other duck species that nest in the North but spend their winter months along the Gulf Coast.

What exactly awaits these birds is unknown. But for the 13 million ducks and another 1.5 million geese that historically have used Louisiana's coastal marshes either for the entire winter or a portion thereof, it likely won't be good.
