Climate Change & Invasive Species

Invasive Species Thriving in Period of Climate Change

Invasive Species Thriving in Period of Climate Change

February 5, 2010 /EIN PRESSWIRE/ According to a study by Harvard University scientists, invasive species appear to thrive during times of climate change, meaning the species could become more prevalent and more destructive.

The study suggests that the invasive species are more apt to thrive because they're better able to adjust to the changing timing of annual activities such as flowering and fruiting.

"These results demonstrate for the first time that climate change likely plays a direct role in promoting non-native species success," says study author Charles C. Davis, assistant professor in organismic and evolutionary biology at Harvard.

One of the control elements for the study was a dataset from author Henry David Thoreau, who cataloged the plants of Walden Pond in the 1850s. His meticulous notes, including flowering times and species occurrences, were compared to present-day conditions at Walden Pond, where plants now bloom as much as three weeks earlier due to early spring thaws.

"In the United States alone the estimated annual cost of invasive species exceeds $120 billion," says Davis.
