Disperses Invasive Plant, Fish Species (Apr 29, 2012)
carp are in direct competition with native aquatic
species for food and habitat. Their rapid population
increase is disrupting the ecology and food web of
the large rivers of the Midwest, including the Missouri
River. Last year's hurricanes and flooding not
only engulfed homes and carried away roads and bridges
in hard-hit areas of the country, it dispersed aggressive
invasive species as well. See additional related news
from USGS's Invasive
Carp Research Program.
Veterinary Officer on the Recent BSE Case
(aka Mad Cow) (Apr 25, 2012)
On Apr 24, USDA confirmed
the nation's 4th case of Bovine Spongiform Encephalopathy (BSE) in an animal
that was sampled for the disease at a rendering facility in central California.
This animal was never presented for slaughter for human consumption, so at no
time presented a risk to the food and milk supply, or to human health in the U.S. See BSE
(Bovine Spongiform Encephalopathy or Mad Cow Disease) from USDA for
End Beetlemania Together (Apr 24, 2012)
beetle (ALB) is an an invasive insect that feeds
on certain species of hardwood trees, eventually killing
them. Since its discovery in the U.S.,
the beetle has caused tens-of-thousands of trees to
be destroyed in Massachusetts, New Jersey, New York,
Illinois, and most recently in Ohio. Help stop the
Asian longhorned beetle's destruction by raising awareness
about the pest and report any
signs or symptoms of an infestation immediately.
Fight Against Cancer May Hold Lessons for Battling Aquatic Invasive
Species (Apr 23, 2012)
Department of Interior.
Lessons learned from the medical community's progress in fighting cancer can
provide a framework to help prevent the introduction and spread of harmful aquatic
invasive species, according to a study released in American Scientist. Scientists
outline five integrated steps used in cancer prevention and treatment that could
be adapted to use in battling invasive species: prevention, early detection,
diagnosis, treatment options and rehabilitation. See article Aquatic
Invasive Species: Lessons from Cancer Research (May-Jun 2012). The study
used the example of invasive American bullfrogs in
the Yellowstone River as a case study for applying the cancer-treatment approach
to aquatic invasions in the Northern Rockies.

Earth Day Network.
Earth Day Network is partnered with National Environmental Education Week (Apr 15-21,
2012), which annually promotes understanding
and protection of the natural world by actively
engaging K-12 students and educators of all environmental
subjects (see Educators'
Network for lesson
plans). See What
You Can Do to help control invasive species.
Details Illinois' Asian Carp Issue, Solutions (Apr
Southern Illinois University Carbondale. The
that large, invasive fish known for leaping out of
a river into boats when startled, now make up more
than 60 percent of the total fish biomass in one
of Illinois' major river systems, a research team
led by Southern Illinois University Carbondale has
found. But the team members’ advice for controlling
the species goes something like this "If you
can't beat 'em, eat 'em." Asian carp are by
far the world’s most cultured fish because
they are a healthful source of protein and perhaps
omega-3 fatty acids. Thus, unlike so many nuisance
or invasive species, these problematic fishes in
the U.S. have
one positive aspect: they can be converted to desirable
food for both human and nonhuman consumption. See Fishing

Purple and Save an Ash Tree (Apr 17, 2012)
These purple traps will be seen this spring
and summer throughout Maryland and 46 other states
that are participating in the 2012 Emerald
Ash Borer (EAB)
survey. The purple traps help State and Federal officials
to uncover signs of the invasive, tree-killing EAB.

Fungus is a European Import (Apr 9, 2012)
Society for Science & the Public. Science
The fungal pathogen Geomyces destructans, introduced into North America
from Europe, is the likely cause of white-nose
syndrome (WNS), an epidemic that has killed millions of North American bats,
according to a study from
the Proceedings of the National Academy of Sciences (Apr 9, 2012).
Study Shows Forest Insects and Diseases Arrive in U.S. Via
Imported Plants (Apr 9, 2012)
University of California - Santa Barbara.
The trade in live plants from around the world has become a major industry in
the U.S., with new imports now valued
at more than $500 billion annually. According to a study conducted by researchers
at UC Santa Barbara's National Center for Ecological Analysis and Synthesis,
however, what has proved to be a boon for the economy has also been shown to
have devastating effects on the environment. The multidisciplinary working group
found that almost 70 percent of the most damaging non-native forest insects and
diseases currently afflicting U.S. forests
arrived via imported live plants.
of Common Pesticide Linked to Bee Colony Collapse (Apr
Harvard University. School of Public Health.
The likely culprit in sharp worldwide declines
in honeybee colonies, known as colony
collapse disorder (CCD), since 2006 is imidacloprid,
one of the most widely used pesticides, according
to a new study from Harvard School of Public Health.
Pinpointing the cause of the problem is crucial because
bees -- beyond producing honey -- are prime pollinators
of roughly one-third of the crop species in the U.S. and
livestock feed. Massive loss of honeybees could result
in billions of dollars in agricultural losses, experts
Americans to Prevent Invasive Pests, Protect American Agriculture (Apr
The U.S. Department of Agriculture's Animal and Plant Health Inspection Service
announced that it is dedicating the month of April to sharing information about
the threat that invasive plant pests, diseases and harmful weeds pose to America's
fruits, vegetables, trees, and other plants-and how the public can help prevent
