• Man Says His Dog Detected His Skin Cancer
  Sat, 22 November 2008
  A man from Banbury near Oxford, England, said his dog sniffed out his skin cancer, reminiscent of reports of trials that have shown dogs can detect cancer, in some cases even when screening tests can't. Chris Tuffrey told the BBC yesterday that his pet Rottweiler, called Beamish, kept nuzzling and licking him and tryi ...
• The Role Predator Selection On Polymorphic Aposematic Poison-frogs
  Sat, 22 November 2008
  Phenotypic variation between populations of the poison frog Dendrobates tinctorius is extremely high throughout their distribution in northern South America. As the bright colors are assumed to act as a warning signal to potential predators, the evolution of this variation within a species raises some interesting questions. ...

  In a recent interview with 60 Minutes, President-Elect Barack Obama and his wife Michelle said that they plan to take their time adopting a first-family dog, waiting until late winter, early spring to pick their new pet. The American Veterinary Medical Association (AVMA) thanks the president-elect for setting a good exampl ...
• Warning Displays May Function As Honest Signals Of Toxicity
  Sat, 22 November 2008
  Are warning signals honest? We are familiar with the fact that dangerous prey animals advertise their toxins with bright colouration (bees, wasps, ladybirds etc). The (antioxidant) molecules used by prey to make themselves brightly pigmented may also be used to prevent them poisoning themselvse with their own toxins. ...
• Outline And Surface Disruption In Animal Camouflage
  Sat, 22 November 2008
  Camouflage is an important strategy in animals to prevent predation. This includes disruptive coloration, where high contrast markings at an animal's edge break up the body shape. Successful disruption may also involve markings found away from the body outline that create 'false edges' more salient than the true body fo ...
• The Strength Of A Female Mate Preference Increases With Predation Risk
  Sat, 22 November 2008
  Females often encounter predators as they look for mates. Not surprisingly, as predation risk increases, females usually search less and they less often prefer males that use conspicuous signals. To the contrary, when we experimentally increased predation risk perceived by mate-searching female fiddler crabs, they cont ...

  The Isle of Skye, Scotland, has yielded the remains of a new species of primitive turtle, Eileanchelys waldmani. Eileanchelys dates from the Middle Jurassic period (164 million years old) and is represented by multiple skulls and shells: it is the most complete turtle known from this time interval. Its anatomy bridges a ...
• Relict Or Colonizer? Extinction And Range Expansion Of Penguins In The Southern New Zealand
  Sat, 22 November 2008
  A startling discovery may change the way we view extinctions. While conducting research on New Zealand's iconic yellow-eyed penguin (Megadyptes antipodes) a team of ancient DNA and palaeontology experts identified a previously unknown penguin species that became extinct before 1500 AD. The new species, the Waitaha Pengu ...
• Range-wide MtDNA Phylogeography Yields Insights Into The Origins Of Asian Elephants
  Sat, 22 November 2008
  We analyse endangered Asian elephants (Elephas maximus) across their range to explain the unusual coexistence of ancient maternal genetic lineages. Such coexistence could result from hybridization between ancestral species, or population isolation and subsequent contact naturally or through trade. Estimating ages of lin ...
