Location Matters: For Invasive Aquatic Species, It's Better to Start Upstream (Sep 26, 2011)
University of Georgia. UGA Today.
Researchers have found that a species invasion that starts at the upstream edge of its range may have a major advantage over downstream competitors, at least in environments with a strong prevailing direction of water or wind currents. The researchers findings, recently published in the Proceedings of the National Academy of Sciences (see article), may help inform the control of invasive species and the conservation of imperiled native species.

UF-led Study: Invasive Amphibians, Reptiles in Florida Outnumber World (Sep 15, 2011)
University of Florida News.
Florida has the world's worst invasive amphibian and reptile problem, and a new 20-year study led by a University of Florida researcher verifies the pet trade as the No. 1 cause of the species' introductions. From 1863 through 2010, 137 non-native amphibian and reptile species were introduced to Florida, with about 25 percent of those traced to one animal importer.

EPA grants help Wayne State University researchers stave off Great Lakes environmental invaders (Sep 12, 2011)
Wayne State University.
Two U.S. EPA grants are helping a Wayne State University researcher keep new non-native invasive species out of the Great Lakes and minimize the impact of those that are already there.

Study Finds that Local Government, Home Owners Are Paying for Damages Caused by Non-native Forest Insects (Sep 9, 2011)
USDA. FS. Northern Research Station.
Non-native, wood-boring insects such as the emerald ash borer and the Asian longhorned beetle are costing an estimated $1.7 billion in local government expenditures and approximately $830 million in lost residential property values every year, according to study by a research team that included scientists with the U.S. Forest Service, Northern Research Station. This study provides the most comprehensive estimates of the costs of non-native forest insects that are currently available for the U.S.

Forests Under Threat from Exotic Earthworm Invasion: Study Shows Humans to Blame for Spread of Non-Native Species (Sep 1, 2011)
Springer Science and Business Media.
It is widely acknowledged that human beings are largely responsible for the widespread alteration of ecosystems on the planet. A recent study traces the ways in which humans are the principal agents of dispersal of exotic earthworms in the forests of Northern America. Recent findings suggest that humans spread earthworms both inadvertently via horticulture and land disturbance, in the tires and underbodies of vehicles, but also knowingly through composting and careless disposal of fish bait.
