Survival of the unfittest can work for bacteria

Survival of the unfittest can work for bacteria

Posted Mon, 28 Mar 2011 14:55:01 GMT by Martin Leggett

Evolution doesn't always favor the fit, according to a new paper in Nature. In certain circumstances, both fit and unfit bacteria can live in diverse communities, even in very simple environments. The key factor is how mutation rates and food-exploiting efficiency are interlinked - it turns out that the best bacteria are often prone to higher levels of mutation.

The Joshua tree could be badly affected by this century's predicted temperature rise - it could be eliminated from up to 90% of its current range. That's the message coming from sloth dung, which scientists have pored over to discern the effect of prior periods of warming on the Joshua tree.

From garbage tip to wildlife haven - new theory for Everglades tree islands

From garbage tip to wildlife haven - new theory for Everglades tree islands

Posted Tue, 22 Mar 2011 16:55:00 GMT by Martin Leggett

Human waste-tips some 5,000 years ago helped to build south Florida's tree-islands, new research being presented at today's American Geophysical Union's Chapman Conference shows. As the waste piled up, the ground became raised enough for trees to colonize - and then stabilize - these island wildlife sanctuaries in the Everglades' Shark River Slough.

Genetic analysis ends 20 years of debate over whether the Amsterdam albatross is separate species

Genetic analysis ends 20 years of debate over whether the Amsterdam albatross is separate species

Posted Mon, 21 Mar 2011 20:24:00 GMT by Helen Roddis

Genetic analysis confirms the world's rarest albatross is a separate species. The Amsterdam albatross is classified as Critically Endangered on the IUCN Red List. It is an extremely large albatross that breeds only on Amsterdam Island in the southern Indian Ocean, where its total population is made up of just 130 individuals. The Amsterdam albatross's breeding range is restricted further still, to a single area of the island known as the Plateau des Tourbieres.

Although large animals in French forests are responsible for a certain amount of damage, they also are effective in contributing to plant diversity. They discovered that one plant, the gypsy flower, was not found at the time of the original survey and only began to appear in 1981. It is now widespread, particularly in areas most frequented by large forest mammals.

According to new research, untrained Barbary macaques are able to differentiate between pictures of familiar and unfamiliar faces. Scientists discovered that the monkeys were able recognise photographs of group members, and spent more time studying pictures of animals that were not part of their social circle.

On the move - 'endangered species should shift with climate'

Posted Fri, 18 Mar 2011 15:01:00 GMT by Martin Leggett

Climate-endangered species should be moved to new compatible habitats, in order to prevent extinctions threatened by global warming. So says a conservationist from the University of York. As long as care is taken is selecting suitable new locations, such radical steps should help slow down rising species loss.

The Andean cat, an elusive species of feline has been discovered to inhabit a much bigger range than was previously imagined. A single photograph of two Andean cats in the foothills of Argentina convinced the WCS researchers and their team to extensively survey 31,000 square kilometres of Argentina's Mendoza and Neuquen provinces.

Pelagic thresher sharks are coming up from the deeps in the Philippines to be cleaned of ectoparasites. This is the first study of wild shark interactions with cleaner fish. The sharks will drown if they do not continuously circulate oxygenated water over their gills, so they make repeat circular passes over the discreet areas of the reef where the cleaner species hold court.

A new study used recordings of lions to prove that older elephants are indeed wiser elephants and that groups are willing to accept the leadership of a wise old head and thrive as a result. Scientists from the University of Sussex have just published the results of their research in the Proceedings of the Royal Society of Biological Sciences and say that elephant groups with elderly female members make better decisions because they defer to the superior knowledge of their seniors.

A wakeup call for the Pacific Northwest

Recent serious earthquakes should serve as a wakeup call to the US Pacific Northwest. What has happened in Japan could well be what will happen in the Pacific Northwest. As if the earthquake wasn't enough, it unleashed a devastating tsunami that has resulted in thousands of deaths and turned large parts of many communities into complete rubble. It is said to be the costliest disaster in world history.
