Using forensic genetics techniques, the UA’s Conservation Genetics Lab is working to protect wild animals and catch the criminals in cases of wildlife crime.
Wildlife face many threats with spreading urbanization, including habitat loss and inbreeding when populations become fragmented and isolated. It doesn’t help that there is a billion-dollar international industry dedicated to the illegal trafficking of wild animals or wild animal parts. (more…)
AUSTIN, Texas — Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists from The University of Texas at Austin advise.
Camille Parmesan, Michael C. Singer and their coauthors published their commentary online this week in Nature Climate Change.
“Yes, global warming is happening. Yes, it is caused by human activities. And yes, we’ve clearly shown that species are impacted by global warming on a global scale,” says Parmesan, associate professor of integrative biology. (more…)
*Steep decline of many animal species warns that Earth is on the brink*
With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years.
Each of these “Big Five” saw three-quarters or more of all animal species go extinct.
In results of a study published in this week’s issue of journal Nature, researchers report on an assessment of where mammals and other species stand today in terms of possible extinction compared with the past 540 million years.
They find cause for hope–and alarm. (more…)
