Triggers Mass Extinctions? Study Shows How Invasive Species Stop
New Life (Dec 29, 2010)
National Science Foundation.
An influx of invasive species can stop the dominant natural process of new species
formation and trigger mass extinction events, according to recent
research results published in PLoS ONE. The study of the collapse of Earth's
marine life 378 to 375 million years ago suggests that the planet's current ecosystems,
which are struggling with biodiversity loss, could meet a similar fate.
Untreated Firewood Poses Threat to Pacific Northwest Forests: Thirty-five
percent of firewood is brought from another location, increasing
risk of invasion from forest pests (PDF | 156 KB) (Dec
Oregon Invasive Species Council.
Moving firewood can increase the risk of introducing new invasive species that
kill native trees. To prevent the spread of these pests, the states of Idaho,
Oregon and Washington launched a tri-state outreach campaign in 2010 to inform
the public about the dangers of moving firewood to Pacific Northwest forests.
The national campaign, Don't Move
Firewood, recommends buying firewood that was cut locally (within 50 miles)
where it will be burned.
2010 Honey Bee Colony Collapse Disorder Progress Report (Dec
are hard at work trying to solve the mystery of Colony
Collapse Disorder, which results in empty hives
and vanished honey bees, and their efforts are detailed
in the new USDA 2010
Colony Collapse Disorder Progress Report unveiled
this week under the auspices of the USDA CCD Steering
Committee co-chaired by Kevin Hackett, ARS'
National Program Leader for Pollination.
Signs Levin's Asian Carp Prevention and Control Act into Law (Dec
Senator Carl Levin.
President Obama signed into law that will aid in the fight against the further
spread of Asian carp in the United
States. The Asian
Carp Prevention and Control Act, S.1421, will add the bighead carp species
of Asian carp to a list of injurious species that are prohibited from being imported
or shipped in the United States under the Lacey
Invasive Species Biologist's Version of "The Night Before
Christmas" by Les Mehrhoff (PDF | 460 KB)
Invasive Plant Control.
A new twist of the original poem 'Twas
the Night Before Christmas', with the perspective of
an invasive species biologist.
Profile -- Thousand Cankers Black Walnut Disease
USDA. NAL. National Invasive Species
Thousand cankers black walnut disease has produced widespread death of black
walnuts in many western states during the past decade. Other species of walnut
such as Arizona walnut, English walnut, and California walnut have all shown
varying degrees of susceptibility to this fungus. Initial symptoms involve a
yellowing and thinning of the upper crown, which progresses to include death
of progressively larger branches. During the final stages large areas of foliage
may rapidly wilt. Trees often are killed within three years after initial symptoms
Discover How Foot-and-Mouth Disease Virus Begins Infection in Cattle (Dec
have identified the primary site where the virus
that causes foot-and-mouth disease (FMD) begins
infection in cattle. This discovery could lead
to development of new vaccines to control and
potentially eradicate FMD, a highly contagious
and sometimes fatal viral disease of cloven-hoofed
animals that is considered the most economically
devastating livestock disease in the world.
Team of Scientists Predicts Continued Death of Forests in Southwestern U.S. Due
to Problems Caused by Climate Change (Dec 13, 2010)
University of California - Santa Barbara. Office
of Public Affairs.
University and government scientists have found that if current climate projections
hold true, the forests of the Southwestern U.S. face
a bleak future, with more severe and more frequent forest fires, higher tree
death rates, more insect infestation, and weaker trees. Past forest studies have
shown that warmer temperatures are associated with wildfires and bark beetle
outbreaks. The findings are published in the Proceedings of the National
Academy of Sciences (PNAS) article Forest
responses to increasing aridity and warmth in the southwestern United States.
Study Essential Oils to Attract Asian Citrus Psyllid (Dec
Chemicals emitted by citrus plants and their
relatives that attract Asian
citrus psyllids are being tested by USDA scientists
and their cooperators, and could help control the
spread of citrus
greening disease transmitted by the psyllids.
Foreign Pests Threaten National Treasures (Dec 6,
University of Central Florida.
Researchers at the University of California at Santa Barbara, Michigan State
University, the University of Central Florida, and the United States Department
of Agriculture's Forest Service analyzed the impact of invasive insects and pathogens
introduced into the United States through 2007, on forests. They found that more
than 455 insects and 16 pathogens are destroying everything from oak trees in
California to redbay trees in Central Florida. Based on the pattern, the researchers
predict one especially destructive pest will sneak into the nation every two
years. Their findings are published in the BioScience article Historical
Accumulation of Nonindigenous Forest Pests in the Continental United States.
to Tackle Invasive Species Threat with Sea Grant, New Marketing
Partner (Dec 5, 2010)
National Professional Anglers Association.
The National Professional Anglers Association (NPAA) will be working in conjunction
with a new marketing partner, the Great
Lakes Sea Grant Network to educate the public about the impact of aquatic
invasive species. The NPAA will make educational materials available to their
members to help them understand and explain the severity of the invasive species
problem. Members will be speaking from tournament stages, at thousands of seminars,
in guide boats and wherever members travel. A special segment will be incorporated
into all NPAA youth fishing clinics.
Pest Danger Closer Than You Think (Dec 1, 2010)
Pennsylvania State University.
In Australia, when crossing from one state to
another, travelers may encounter a quarantine stop
and may be required to forfeit recently purchased
fruits and vegetables as a hedge against invasive
pests. But in the U.S.,
crossing state lines is freewheeling, according to
researchers from the U.S.,
Australia and New Zealand, who evaluated the threat
of invasive pests to states from within the country.
Researchers reported "We concluded that the
immediate threat from known invasive insect pests
is greater from within the U.S. than
without. Our findings have significant implications
for biosecurity policy and the need to consider security
measures beyond established national borders."
