Home, Home On The Range: How Much Space Does An Animal Really Need?

Instead of wandering around aimlessly, most animals tend to stay in a certain area -- known as their home range. Understanding an animal's home range has been a central focus of ecological research since Darwin's time. But while explaining why different sized species need different amounts of space is relatively easy, a study from the October issue of the American Naturalist tackles a much more complex question: What determines differences in home range size among individuals of one species?

   01-18-2007 · EurekAlert!
   Some 50 million Americans have hypertension, that is, blood pressure measuring above the normal range (less than 120/80 mmHg). If untreated, it can lead to heart attacks, strokes, or kidney disease. Lifestyle changes are the first-stage treatment for the disease, but if they fail, medications are prescribed. In a soon-to-be-released study using an animal model, scientists have found that tanshinone IIA, an active ingredient of danshen, reduces blood pressure.

New research in the online open access journal BMC Genomics shows how S. aureus makes itself at home in human lung cells for up to two weeks.

   The wild tiger's population trajectory is "catastrophic" and its continued existence cannot be assured without improved conservation efforts, according to a new assessment. The area occupied by the animal has declined by 41 percent over the past decade and now amounts to just 7 percent of its historic range.

7. Computer savvy canines
   11-28-2007 · EurekAlert!
   Like us, our canine friends are able to form abstract concepts. Friederike Range and colleagues from the University of Vienna in Austria have shown for the first time that dogs can classify complex color photographs and place them into categories in the same way that humans do. And the dogs successfully demonstrate their learning through the use of computer automated touch-screens, eliminating potential human influence. The study has just been published online in Animal Cognition.

   According to a recent study, predicting the impact of climate change on organisms is more complicated than simply looking at species northern and southern range limits. Studying the California Sea Mussel -- Mytilus californianus, Brian Helmuth (University of South Carolina) and colleagues from the University of California-Santa Barbara, the University of British Columbia-Vancouver and Oregon State University measured body temperatures of this mussel along most of its range, from Washington to Southern California.

    In a new study in animals, University of Michigan researchers report that a combination of high doses of vitamins A, C, and E and magnesium, taken one hour before noise exposure and continued as a once-daily treatment for five days, was very effective at preventing permanent noise-induced hearing loss. The animals had prolonged exposure to sounds as loud as a jet engine at take-off at close range.
