From the deep -- Researchers find new species of sea anemone

...cal change, whether it's through whaling or global climate change," she said, and also pointed out that there are now far fewer major whale migrations along the California coast. While the flesh of a dead whale decomposes within weeks, the bones can last anywhere from 60 to 100 years. "As that happens,...

Scientists discover new life in the Antarctic deep sea

...arine species and how they can adapt to changes in climate and environments." Dr Katrin Linse, marine biologist from British Antarctic Survey, says, "What was once thought to be a featureless abyss is in fact a dynamic, variable and biologically rich environment. Finding this extraordinary treasure ...

Improved predictions of warming-induced extinctions sought

...tested, that explanations of extinction other than climate change need to be more thoroughly considered, and that better data should be brought to bear on the problem, especially information from the fossil record of Quaternary ice ages. The authors acknowledge, however, that they do not fully understand why...

Discovery of new cave millipedes casts light on Arizona cave ecology

...nd wetter, millipedes lived in leaf litter. As the climate warmed, they sought refuge in caves, where the subterranean realm provides more constant climatic conditions enabling their survival. Representing two distinct species (one occurring in one cave on the South Rim, the other in two caves on the Nort...

How fish species suffer as a result of warmer waters

Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. This applies also to fish populations. Previous studies demonstrating a link between global warming and declining fish stocks were based enti...

Are we killing the world's oceans?
