Prairie Dog Polygamy Pros And Cons

redOrbit Staff & Wire Reports - Your Universe Online While polygamy can increase the risk of exposure to diseases and parasites, the likelihood that female prairie dogs will give birth to more offspring often makes mating with more than one male worth the risk, new research claims. The paper, which was prepared by behavioral ecologist John Hoogland of University of Maryland, reported that the herbivorous rodents that mated with multiple males were likely to rear more offspring...

Lawrence, Kansas (PRWEB) August 19, 2013 Female organisms commonly copulate with multiple male partners, and prairie dogs are no exceptions. The question is, why do females undergo...

Climate Change Altered Hibernation For Rocky Mountain Animal Species
2012-08-10 13:30:42

redOrbit Staff & Wire Reports - Your Universe Online For a species of Rocky Mountain ground squirrel, climate change is causing a late wake-up call from hibernation and the effect is deadly. Examining data on a population of Columbian ground squirrels, a University of Alberta-led international research team found a trend of late spring snow falls has delayed the animals' emergence from hibernation by 10 days over the last 20 years. "Columbian ground squirrels are on a tight...

Discovery puts scientists closer to human application Hibernation is an essential survival strategy for some animals and scientists have long thought it could also hold promise for human survival. But how hibernation works is largely unknown. Scientists at the University of Alaska Fairbanks have successfully induced hibernation at will, showing how the process is initiated. Their research is published in the July 26 issue of The Journal of Neuroscience. A hibernating animal has a reduced...

Prairie dogs, once abundant in the Rocky Mountains and Great Plains, have been decimated in recent decades by plague "“ a virulent bacterial disease spread by fleas. Plague outbreaks periodically sweep through large prairie dog towns with thousands of inhabitants, killing virtually the entire population within months.

Researchers from the Center for Ecological Research and Forestry Applications (CREAF) and the Autonomous University of Barcelona (UAB) have demonstrated, using a map of the potential distribution, the alpine marmot's capacity for adaptation in the fields of the Pyrenees. Its quick proliferation makes it a successful example of species introduction. At the end of the Pleistocene (10,000 years ago), the increase in temperatures brought an end to the alpine marmot (Marmota marmota) in the...
