Brett Smith for redOrbit.com - Your Universe Online In 1975, 16 female and 4 male bighorn sheep were deliberately introduced to Tiburón Island, a large and mostly uninhabited island in the Gulf of California. However, these sheep are not necessarily an invasive species as a new report in the journal PLOS ONE has found that these animals actually lived on the island before and went extinct between the 6th and 9th centuries. Bighorn sheep were reintroduced to the island as part of a...

SYRACUSE, N.Y., May 31, 2011 /PRNewswire/ -- Pro Staffer for www.ScoutLookWeather.com and the bow hunting world's elite hunter, Tom Miranda, reached a new pinnacle this month by concluding his quest to harvest the Super Slam of big game animals with a bow. The last of his 29 animals, recognized by the Pope & Young Club, was fittingly the coveted desert bighorn sheep. Unquestionably, the North American Super Slam remains bow hunting's highest achievement with few having ever attained...

Canadian scientists say they have completed a study that links personality, survival and reproductive success in male bighorn sheep. The researchers, led by University of Quebec at Montreal Professor Denis Reale, said their findings not only advance the knowledge of bighorn sheep, but also offer insight into personality differences in animals and humans from an evolutionary perspective. Since 1969, several teams of researchers have been studying a population of bighorn sheep in Alberta,...

The team led by Denis Reale, a professor in the Department of Biological Sciences at UQAM and Canada Research Chair in Behavioral Ecology, recently completed a study showing the link between personality, survival and reproductive success in male bighorn sheep. Their results were published in an article entitled "Male personality, life-history strategies and reproductive success in a promiscuous mammal" in the prestigious Journal of Evolutionary Biology 22(8): 1599-1607. In addition to being a...

University of Alberta researcher David Coltman wrestles with bighorn mountain sheep to gauge their personalities.Coltman, a U of A biology professor, is part of a team that traps the animals in a plywood enclosure on a mountaintop in the Rockies. He and the research team are trying to figure out if personality type has anything to do with how long a mountain sheep lives or how many offspring it produces.The extreme ends of the personality measurement are bold and submissive. For example, with...

U.S. biologists say the 700-mile security wall under construction along the United States-Mexico border could significantly threaten wildlife. The scientists said the wall would alter the movement and connectivity of wildlife and the animals' potential isolation might be a threat to populations of some species. But the researchers said technology and design alterations could dramatically improve the potential for animals to move more freely between the two countries. Oregon State University...

A 700-mile security wall under construction along the United States' border with Mexico could significantly alter the movement and "connectivity" of wildlife, biologists say, and the animals' potential isolation is a threat to populations of some species.However, technology and alterations to the design could dramatically improve the potential for animals to move more freely between the two countries, the scientists added.Results of their study are being published in the journal Conservation...

Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep. The effects of a changing climate on a population of bighorn sheep can be mathematically predicted, as described in a recent paper recommended by Faculty of 1000 Biology members Barry Brook and Lochran Traill. Researchers from Germany, the US, and Mexico studied a population of bighorn sheep introduced to Tiburon island, Mexico, in...

Scientists say they're studying bighorn sheep on an island off the coast of Mexico to determine the effects of climate change on endangered species. The sheep, brought to Tiburon Island in 1975, are not at risk from disease or predators, said Barry Brook, a researcher with Faculty of 1000, a London-based cooperative of international scientists. Climate change is the only variable threat to the sheep, making them good subjects for a mathematical model aimed at predicting the effects of such...

Bighorn Sheep, Ovis Canadensis
2012-05-10 12:18:52

The bighorn sheep (Ovis Canadensis) can be found in North America. There are three currently accepted subspecies of this sheep. The range of the bighorn sheep depends on these subspecies. The Sierra Nevada and Rocky Mountain bighorn sheep dwell in the cool mountainous areas of the United States and Canada, while the Desert bighorn sheep are native to the hotter desert areas of the southwestern United States. Bighorn sheep prefer habitats located in rocky, grassy slopes, and alpine meadows....
