Trade Threatens Public Health and Ecosystems: Study outlines potential
risks to native species and human health (Apr 29,
National Science Foundation.
A research team including Brown University has
found that the U.S. wildlife
import system is broken. The poorly regulated U.S. wildlife
trade can lead to devastating effects on ecosystems,
native species, food supply chains and human health.
Reducing the Risks of the Wildlife Trade (May 1,

America Works to Halt Invasive Species (Apr 23, 2009)
Commission for Environmental Cooperation.
The new report, Trinational
Risk Assessment Guidelines for Aquatic Alien Invasive Species was developed
in cooperation with experts from Canada, Mexico and the United States. These
guidelines will be used as a tool for North American resource managers to assess
the risk of introducing nonnative species into a natural ecosystem.
to Receive DOI Cooperative
Conservation Award (Apr 22, 2009)
Fort Collins Science Center.
A team of scientists from the USGS Fort
Collins Science Center are being recognized with the U.S. Department
of the Interior's Cooperative Conservation Award on May 7. Their Advanced Invasive
Species Modeling Room leverages research conducted by the USGS and
the Natural Resource Ecology Laboratory at Colorado State University to better
document, map, and predict the spread of harmful plants, animals, and diseases
in the United States.
Biofuel Crops Pose Invasive Pest Risk (Apr 22, 2009)
Biofuel crops being promoted and planted as a "green" renewable solution
to energy needs might actually be aggressive invasive pests, caution University
of Hawaii-Manoa researchers. The findings, "Assessing
Biofuel Crop Invasiveness: A Case Study," are reported in the journal PLoS
ONE, a Public Library of Science resource.
Put Price Tag on Invasive Species: Research reports
costs of invasive species' damage to ecosystem services (Apr
Ecological Society of America.
In a study, How
well do we understand the impacts of alien species on ecosystem services? A pan-European,
cross-taxa assessment (published in Frontiers in Ecology and the Environment
e-view), ecologists have listed the invasive species that cause the most harm
to environment and cost the most money to control.
Profile -- Alligatorweed
USDA. NAL. National Invasive Species
Alligatorweed is a perennial aquatic weed introduced to the southern U.S. from
South America in the early 1880's from ballast water. Alligatorweed infestations
blocked rivers, canals, and ditches across the South, often causing severe flooding.
Alligatorweed forms dense mats that crowd out native species and impede recreational
activities such as boating, swimming, and fishing.
Network Partners with National Environmental Education
April 12-18, 2009
Earth Day Network.
Earth Day Network is partnered with National
Environmental Education Week, which annually promotes understanding and protection
of the natural world by actively engaging K-12th grade students and educators
of all environmental subjects (see Educators'
Network for lesson plans).
for Non-native Oysters in Bay Dropped: Foreign
Species Deemed Ecologically Dangerous (PDF |
163 KB) (Apr
Virginia, Maryland and the Army Corps of Engineers announced a new strategy Monday
for restoring oysters in the Chesapeake Bay that excludes any use of exotic
Asian oysters. The decision ends years of debate about whether to introduce
an Asian oyster into the bay and concludes nearly five years of formal study,
costing $17 million in state and federal funds. The preferred alternative will
focus solely on reviving native oysters - by building more artificial reefs in
the Bay, expanding oyster farming opportunities and growing more baby oysters
at more hatcheries.
Foot-and-Mouth Disease: Novel Technologies Improve Detection
and Control (Apr 2009)
USDA. Agricultural Research Service Magazine.
Scientists at the ARS Plum Island Animal Disease Center are using Infrared thermography
(IRT) cameras to see what human eyes can't. IRT cameras can identify at-risk
cattle 48 hours before they begin to show any clinical symptoms of foot-and-mouth
disease. In the event of an outbreak, this technology could facilitate rapid
containment of the disease.
