Deforestation is Stressing Mammals - One Green Planet

As forests shrink, mammals are stressed out— with possible fallout for humans

Humans aren’t the only ones feeling anxiety about environmental destruction. As forests shrink, small mammals are also feeling stressed, and we can tell by their fur. A team of scientists collected fur samples from 106 small rodents and marsupials in six forest fragments in the Atlantic Forest of Paraguay. After grinding each fur sample into […]

Deforestation ‘stressing animals out’, scientists warn Harry Cockburn © Provided by The Independent Some people may be panicking about our own species’ rampant destruction of the natural world, but we are not the only ones concerned. The animals directly impacted by deforestation appear to be expressing more hormones associated with stress, according to bleak new research by American scientists. Researchers who took samples of hormones which accumulate in fur found rodents and marsupials living in smaller remaining patches of South America’s Atlantic Forest are under more stress than those living in more intact areas of the forest. The Atlantic Forest stretches along Brazil’s Atlantic coastline and into Argentina and Paraguay. It is one of the most diverse ecosystems on the planet, second only to the Amazon, but only a fraction of the original forest remains.

It turns out, humans aren t the only ones stressing out by analyzing hormones that accumulate in fur, researchers found that rodents and marsupials living in smaller patches of South America s Atlantic Forest are under more stress than ones living in more intact forests. We suspected that organisms in deforested areas would show higher levels of stress than animals in more pristine forests, and we found evidence that that s true, says Noé de la Sancha, a research associate at the Field Museum in Chicago, Associate Professor of Biology at Chicago State University, and co-author of a new paper in
