Study: Warmer Climate Is Sending Species Uphill

University of Connecticut ecologists studying plant and animal movement in Costa Rica are finding that species may move up mountain slopes as the climate warms but areas left behind will have little to replace them:

AFP in the Vancouver Sun reports:

“In a rare study on the impact of global warming in the tropics, University of Connecticut ecologist Robert Colwell and colleagues worked their way up the forested slope of a Costa Rican volcano to collect data on 2,000 types of plants and insects.

‘Half of these species have such narrow altitudinal ranges that a 600-meter (2,000 feet) uphill shift would move these species into territory completely new to them,’ said a summary of their article released Thursday.”  See full article.
