Local range estimation in wild animals
02-13-2007 · EurekAlert!A new class of computational methods have been developed to construct distributions of where such monitored organisms are most likely to be found in space and time using this data, and are much more accurate than previous methods when dealing with large sets of data.

- Home, Home On The Range: How Much Space Does An Animal Really Need?
10-05-2006 · ScienceDaily
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?

- UCF student's research with Disney giraffes may help conserve several species
01-29-2007 · EurekAlert!
University of Central Florida doctoral student Jennifer Fewster is studying giraffe poop at Disney's Animal Kingdom Lodge in Lake Buena Vista in an effort to figure out what the animals eat in the wild and to improve the nutrition of those in captivity. Results from they study may also help protect other herbivores in the wild.

- Threats to wild tigers growing
06-01-2007 · EurekAlert!
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.

- Nutrients might prevent hearing loss, new animal study suggests
03-28-2007 · EurekAlert!
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.

- Finding an answer to Darwin's Dilemma
12-08-2006 · EurekAlert!
The sudden appearance of large animal fossils more than 500 million years ago -- a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" -- may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their ecosystems.

- Active ingredient in common Chinese herb
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 protein super-family discovered with critical functions for animal life
02-13-2007 · EurekAlert!
Biologists have discovered a new super-family of developmental proteins that are critical for cell growth and differentiation and whose further study is expected to benefit research on cancer and the nerve-cell repair. The protein super-family, which existed before the emergence of animals about 850 million years ago, is of major importance for understanding how life evolved in primordial times. The discovery will be described in the February 14, 2007 issue of the journal PLoS ONE.

- Penn Veterinary Medicine report new strategy to create genetically-modified animals
09-20-2007 · EurekAlert!
Researchers at Penn Vet have demonstrated a new strategy for genetic modification of large animals by employing a virus that transfers genetic modifications to male reproductive cells, which passes naturally to offspring. Scientists at the Center for Animal Transgenesis and Germ Cell Research at Penn introduced adeno-associated virus to germline stem cells in goats and mice. AAV stably transduced male germ line stem cells and led to transgene transmission through the male germ line.

- Manipulating nature: Scientists query wildlife birth-control method
02-11-2007 · EurekAlert!
Australian scientists are raising concerns over the unpredictable nature of a contraceptive vaccine that aims to control populations of wild animals, such as rabbits and foxes.Writing in the latest issue of the journal, Reproduction, UNSW genetics expert Professor Des Cooper warns that the immuno-contraception method is not fully effective and is manipulating natural reproduction in ways that can't be predicted or controlled.

- Microbes compete with animals for food by making it stink
11-01-2006 · EurekAlert!
Microbes may compete with large animal scavengers by producing repugnant chemicals that deter higher species from consuming valuable food resources, a new study suggests.Ecologists have long recognized microbes as decomposers and pathogens in ecological communities. But their role as classic consumers who produce chemicals to compete with larger animals could be an important and common interaction within many ecosystems, according to a paper published this week in the journal Ecology.
