More PROVEN human destruction of nature

Poaching and habitat loss have reduced forest elephant populations in Central Africa by 63 percent since 2001.

This widespread killing poses dire consequences not only for the species itself but also for the region’s forests, a new Duke University study finds.

“Without intervention to stop poaching, as much as 96 percent of Central Africa’s forests will undergo major changes in tree-species composition and structure as local populations of are extirpated and surviving populations are crowded into ever-smaller remnants,” said John Poulsen, assistant professor of tropical ecology at Duke’s Nicholas School of the Environment.

Cattle ranching, agriculture and other human activities are breaking up Costa Rican forests into isolated patchy fragments, but causing more problems for native plant populations than for monkey species sharing the same habitat.

A study published in the journal Primates shows that while plants growing near the edges of cleared regions are negatively impacted by human activity, sharing the same habitat do not fare as poorly.

Human encroachment is the leading cause of death among Ontario’s at-risk birds of prey, according to a first-ever University of Guelph study.

“The most common cause of was from trauma, which often included colliding with a vehicle or flying into stationary objects, such as buildings,” said Nemeth. “The second most common cause was emaciation, which often occurs when the landscape changes in a way that hinders them from successfully hunting and finding shelter.”

This was the first study to examine the most common causes of death in raptors in Ontario.
