Dangerous liaisons - how Ireland's brown bears shaped polar bear evolution

Dangerous liaisons - how Ireland's brown bears shaped polar bear evolution

Posted Thu, 07 Jul 2011 16:00:00 GMT by Martin Leggett

Modern polar bear can trace their family tree back to brown bears from Britain and Ireland, says a team publishing in Current Biology today. Their extensive work on mitochondrial DNA shows that polar and brown bears have often 'gotten intimate' in the past - and such liaisons may be critical for the future survival of polar bars.

Hotspots driving tectonic plate movement

Hotspots driving tectonic plate movement

New research published in Nature shows that plumes of hot magma are responsible for the movement of whole continents. This movement is driven by the heat of the Earth's core, causing the viscous substance beneath the Earth's crust to flow and move the plates above, like pieces of toast floating in a massive bowl of hot beans.

Gray whales cruised through Ice Age on krill and herring

California gray whales may be able to quadruple their numbers to nearer 100,000, say paleontologists looking at how these encrusted denizens of the Pacific survived the last Ice Age. The paper, appearing online in today's edition of PloS ONE, shows that adaptable gray whales can shift their feeding to krill and herring; they could even thrive with rising sea-levels, the paper's authors suggest.

By using the latest dating techniques Australian scientists believe that parts of the country are at risk from overdue volcano eruptions and are calling for emergency plans to be put in place. There are concerns that no plans are in place to deal with eruptions or seismic activity.

Minuscule water boatman boasts loudest shout of them all

A minute species of water boatman has been shown to be able to 'turn up the volume to 11', and so out-shout all other animals in the noise-making department, according to a study being presented the Society for Experimental Biology annual conference. At 99 decibels, the mating call of Micronecta scholtzi blasts out louder than elephant or whale, when body weight is taken into consideration.

Sea urchins don't have eyes, yet they react to light. How? Researchers from Sweden argue that the whole creature is studded with light sensors making it one giant seeing eye. So, while they have no eye as such, the urchins have many many light receptors, found on the end of the feet that cover their entire body.

Academics don't often call for less study, but experts on the Great Lakes in North America warn that unless radical action is taken quickly, Asian carp will cause terrible damage to native species and fishery economies. The study calls for action and even calling in the army in the shape of the U.S. Army Corps of Engineers to help separate the lakes from the carp's Mississippi home.

An innovative use of MRI scanners and tarantulas has revealed intriguing new information about a spider's heart - it may show a double-beat, similar to that felt by humans. The research, being presented at this week's annual conference of the Society for Experimental Biology, in Glasgow, also holds out the possibility of investigating useful properties in spider venom, and the evolution of the brain.

Just how many species of desert tortoises are there? For 150 years since the species' discovery, it was believed that the desert tortoise is one species. However, evidence has been mounting that desert tortoises should in fact be two separate species.

Right time for whales to return to New Zealand's calving grounds

The playful antics of the gentle-but-gigantic right whales may be about to return to New Zealand, after an absence of 50 years - according to a new study published in Marine Ecology Progress Series. These formerly teeming calving grounds are being rediscovered by intrepid pioneers from near the Antarctic - and this may herald a return to the stunning yearly spectacle, last seen 100 years ago, before the whalers laid waste to these graceful giants.

The hidden world of the feathered color-spectrum has been mapped out in detail, in a new study of color - as seen from the bird's point of view - just published in Behavioral Ecology, out today. It seems for all their dazzle to our eyes, there is even more possibility for bird's evolutionary display to explore – as two-thirds of possible colors have yet to be painted on their plumage.

After a decade of surveying that has pooled marine experts from institutions from across the globe, the first results of TOPP - a critical part of the Census of Marine Life – are published in Nature today. They show that the Pacific Ocean's top predators move across an ever-changing oceanic landscape, in order to enjoy shifting biological feasts, that move with the the currents and the seasons.

Flowers need bees and birds and bees and many species of birds need flowers, but as global warming changes the flowering calendar of mountain plants, this symbiotic relationship could fail disastrously for both parties.

Captive chimps suffer from post-traumatic stress disorder (PTSD), depression, and other mental illnesses, researchers find. Laboratory testing, capture, isolation from social groups, and even captivity in "enriched" environments lead to abnormal behavior in chimps, two studies show.

Researchers have discovered that Google Earth provides a novel and inexpensive way to monitor animal behaviour. The beauty of Google Earth for scientists is that animal behaviour which leaves a footprint on the landscape can be observed remotely.
