A group of more than 90 pilot whales were beached on a spit on New Zealand’s South Island on Monday. Thirty-six of the whales had died by Tuesday, the Associated Press reported.

A final attempt to refloat the whales will be made during high tide today.

According to the Australian Associated Press, the pod has repeatedly been stranded on the spit, in Golden Bay on New Zealand’s South Island.

“We tried to refloat the other 40 and they simply wouldn’t move. We tried pushing them out to sea, and they just wouldn’t go,” said the Department of Conservation’s area manager John Mason to the New Zealand Herald.

Close to 50 volunteers are helping the rescue efforts with people traveling from as far as Australia, Auckland and Invercargill to participate. The volunteers were working three to a whale and were Read more…

AUTHORITIES are investigating the deaths of thousands of fish in the Swan River.

River users reported finding about 5000 dead fish in the upper reaches of the river during the weekend.

Swan River Trust river systems manager Mark Cugley said officers were investigating the extent of the kill and what had caused it.

“The Trust was notified by the public on the weekend that a number of fish were seen floating in the water between Middle Swan bridge and the Ellen Brook confluence,” Mr Cugley said.

“Most of the fish appear to be juvenile black bream with the remainder being trumpeter.”

Mr Cugley said monitoring results had shown there were Read more…

A SIGNIFICANT fish-kill was discovered in the River Bandon in Cork after a member of the public alerted staff of Inland Fisheries Ireland.

More than 350 salmon and trout were found dead over a one-mile stretch of the river. The fish kill included salmon of up to 2.7kg (6lb). Many of the fish were decomposing.

An extensive search revealed no source of pollution and it was concluded that the event that caused the kill had passed by the time investigations began.

Head of fishery operations Dr Greg Forde, said: “During the summer, rivers are particularly vulnerable and factories and farmers Read more…

Twenty Percent of All Mammals at Risk of Extinction

At least twenty percent of all known mammals are nearing extinction, with large species at greatest risk, according to a recent assessment of the conservation status of 5,487 mammals.

Expanding agriculture and hunting are the primary extinction drivers, according to the findings, published in the latest Philosophical Transactions of the Royal Society B. That means humans causing the most severe mammal extinction period in history.

“The example I often tend to bring up is Tasmanian Devil, familiar to many from the Looney Tunes cartoons, because it’s an example of how a species that is common, or at least not uncommon, can suddenly, through the emergence of a novel threat, be plunged into a steep decline,” lead author Michael Hoffmann told Discovery News, explaining that a relatively Read more…

“Trophic Downgrading of Planet Earth,” a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth’s terrestrial, freshwater, and marine ecosystems.

The paper claims that the loss of apex consumers from ecosystems “may be humankind’s most pervasive influence on nature.” The research was funded primarily by the Institute for Ocean Conservation Science at Stony Brook University with support from The Pew Charitable Trusts.

The paper is co-authored by the Institute’s executive director, Dr. Ellen K. Pikitch, and the lead author is Dr. James A. Estes, professor of ecology and evolution at the University of California at Santa Cruz.

The review, conducted by an international team of 24 scientists, illuminates the Read more…

Dead Penguins Washing Ashore With Disturbing Regularity

Last week, several dozen dead and dying Magellanic penguins were discovered on beaches throughout south Brazil, apparent victims of an oil spill. So far more than 140 penguins have been transfered to animal care facilities to be cleaned and rehabilitated, while an untold number more have already perished from contaminated waters. If this fact alone weren’t cause enough for concern, what’s more troubling is that it’s hardly an isolated incident. For the last ten years, with disturbing regularity, penguins have been washing ashore starving or covered in oil. And while the origins of these annual mass deaths remain officially a mystery — one biologists believes Read more…
