Chronic wasting disease is here

. . . North Dakota is no longer CWD free. Last fall a deer hunter in unit 3F2 (west side of Missouri River, bordering South Dakota) killed a mule deer buck that appeared to be sick.

He reported it and test samples were taken of the deer and tested along with the state’s regular testing protocol that included 3,000 samples taken this year.

Last week, after testing only two thirds of those samples, the test result from that sick mule deer came up positive for CWD.

The rest of the samples will be tested over the next month.

City pollution harms sea turtles

University of Queensland researchers have discovered that one of the effects of inceased human population is stress being placed on the environment leading to sick turtles.

Staff from the Veterinary Marine Animal Research, Teaching and Investigation (Vet-MARTI) unit within the School of Veterinary Science have been conducting an in-depth investigation to determine the diseases and causes of death in green and loggerhead turtles in Southern Queensland.

Director of Vet-MARTI, Dr Mark Flint, has found that these turtles are dying due to the environment they live in, rather than from the ingestion of foreign items.

How Will Climate Change Affect Arctic Migrations?

. . . The teeming waters are among the richest in the world yet the least studied because of difficulties overcoming months of dark days and impassable frozen seas.

Arctic scientists say they've just begun to document the polar cap's biological diversity. They don't know how the animals are responding to global warming, where they're feeding, how their icy habitat has been affected or how the ecosystem's food web has changed.

The researchers want to fill crucial data gaps so that they can advise how best to safeguard the wild Arctic. Protection is crucial, they say, as the Northwest Passage begins to open year round and increasing access offers new chances for development. Nations, including the United States, are clamoring to exploit oil and gas resources, rich fish supplies and tourist and commercial vessel trade.
