University of New Haven.
The invasive sea squirt, Styela
clava, has now been discovered along the Eastern Seaboard as far south
as Bridgeport Harbor and poses a significant danger to Connecticut's $30 million
shellfish business, according to field research conducted by a researcher at
the University of New Haven, and several students. Also see video and media
Matters: For Invasive Aquatic Species, It's Better to Start Upstream (Sep
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
National Public Lands Day -- Sep 24,
National Environmental Education Foundation.
National Public Lands Day is the nation's largest hands-on volunteer effort to
improve and enhance the public lands American's enjoy. In 2010, volunteers removed
an estimated 20,000 pounds of invasive
species. Get involved, find
a site and help eradicate non-native invasive plants!
Study: Invasive Amphibians, Reptiles in Florida Outnumber World (Sep
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.
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
Finds that Local Government, Home Owners Are Paying for Damages
Caused by Non-native Forest Insects (Sep 9, 2011)
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.
Cameras Open New View of America's West (Sep 6, 2011)
An ARS aerial survey
from a light sport plane has found the first evidence that the invasive weed
leafy spurge is displacing seedlings of native plants three years after Idaho's "Deep
Fire Burn" wildfire.
Under Threat from Exotic Earthworm Invasion: Study Shows Humans
to Blame for Spread of Non-Native Species (Sep 1,
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.
