...s similar to the rate of deforestation in tropical forests today. To assess the biodiversity of the Midwest's remaining wetlands, Jenkins and his colleagues studied crustaceans in 13 ephemeral ponds near Bluff Springs, Illinois; the ponds were wide and shallow, three feet deep at most.

In Guyana, one team found that when canopy habitat is destroyed, canopy insects can't live in the und...Emerging threats to tropical forests
Tropical forests are subjected to myriad environmental alterations, many of which are relatively new or poorly understood. These changes may interact additively or synergistically, posing even greater threats to tropical ecosystems. This symposium, to be held during...Evidence for orangutan culture
...legal logging and other habitat destruction in the forests of Sumatra and Borneo could not only threaten further research into the earliest origins of culture, but continue the dangerous decline in orangutan populations.
