The pre-hatching calls of baby Nile crocodiles actually mean something to their siblings and to their mothers. The calls -- which are perfectly audible to humans and sound like "umph! umph! umph!" -- tell the others in the nest that it's time to hatch, according to research in Current Biology. Those cries also tell the mother crocodile to start digging up the nest.

A large 3-D model of the Blue Tongue virus has been created by WMG engineering researchers at the University of Warwick that will help biologists devise new ways to combat the virus, and protect millions of livestock from infection. The model is 5,200,000 times the size of the real thing.
Reliance On Unverifiable Observations Hinders Successful Conservation Of Wildlife Species

Researchers from the US Forest Service's Pacific Northwest and Rocky Mountain Research Stations examined three cases of biological misunderstandings in which unverifiable, anecdotal observations were accepted as empirical evidence. Ultimately, they found that this acceptance adversely affected conservation goals for the fisher in the Pacific states, the wolverine in California, and the ivory-billed woodpecker in the southeast by vastly overestimating their range and abundance. The researchers' findings appear in the current issue of the journal BioScience.

New research reveals locations in a dog's DNA that contain genes that scientists believe contribute to differences in body and skull shape, weight, fur color and length -- and possibly even behavior, trainability and longevity.
Birds Migrate Earlier, But Some May Be Left Behind As Climate Warms Rapidly

Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate.
