of Transportation Announces $4 Million Investment to Combat Invasive
Species in Great Lakes (Nov 22, 2010)
The Maritime Administration is funding a $4 million project to help prevent the
spread of invasive aquatic species found in cargo ships in the Great Lakes. The
funding is part of the Obama Administration's Great
Lakes Restoration Initiative, the largest federal investment in the Great
Lakes in 20 years.
Hemlock Hybrids Tolerant to Invasive Hemlock Woolly Adelgid (Nov
New hemlock hybrids that are tolerant to the invasive insect known as Hemlock
Woolly Adelgid (HWA) have been created by USDA scientists.
Over the past few decades, two hemlocks native to the United States—Tsuga
Canadensis (Eastern hemlock) and Tsuga caroliniana (Caroline hemlock)—have
been under attack by the HWA. Originally from Asia, this aphid relative has spread
to forests and backyards in 17 eastern states, killing hemlock trees and devastating
natural ecosystems. The scientists and their colleagues crossed hemlock species
native to the U.S. with germplasm—collected
in Asia—of hemlocks that have shown tolerance to the insect. The hybrids
are appealing not only due to their tolerance, but because they have good vigor
and shape. Still, the researchers have several years of testing to complete before
they can release these hybrids. Read more about the research in the article Saving
America's Hemlocks, published in the Nov/Dec 2010 issue of Agricultural
Live Animal Imports. Agencies Need Better Collaboration to Reduce
the Risk of Animal-Related Diseases (Nov 8, 2010)
that the Secretaries of Agriculture, Health and
Human Services, Homeland Security, and the Interior
develop a strategy to address barriers to agency
collaboration that may allow potentially risky
imported animals into the U.S. and
jointly determine data needs to effectively oversee
imported animals. The GAO reviewed
joint strategies developed by interagency working
groups, such as the National
Invasive Species Council's Management Plan and
Aquatic Animal Health Plan. The GAO Highlights Agencies
Need Better Collaboration to Reduce the Risk of
Animal-Related Diseases (PDF | 89 KB) provides
a summary of the report and recommendations.
Offer Effective Weed Control, but Native Vegetation Hard to Re-establish (Nov
Allen Press. Rangeland Ecology & Management.
With the help of the weed-eating flea beetle,
researchers significantly reduced infestations
of a non-native plant, Leafy
Spurge, on Montana rangeland. This biological
method of weed control worked effectively over
the course of a 9-year study, but rather than native
plants returning to flourish in the absence of
leafy spurge, other non-native species became dominant
in its place. By the study’s end in 2006,
leafy spurge foliar cover was reduced 80% to 90%
compared to 1998 assessments. While other vegetation
did increase once this invader was controlled,
another non-native plant, Poa spp., became
the dominant species. The findings are published
in the Rangeland Ecology & Management article Lack
of Native Vegetation Recovery Following Biological
Control of Leafy Spurge.
Anglers Join Invasive Species Fight (Nov 2, 2010)
National Professional Anglers Association.
Forever and the National Professional Anglers
Association (NPAA) have formed a partnership to fight
invasive species. Wildlife Forever's collaborative
conservation efforts include the Threat
Campaign, an education outreach effort designed
to enlist the support of the public and encourage
them to take action. This new partnership will empower
the more than 400 NPAA members and a growing number
of NPAA Supporting Partners with the facts they need
to help eliminate the threat that invasive species
pose to our waterways.
Profile -- Brown Marmorated Stink Bug
National Invasive Species Information Center.
The brown marmorated stink bug is an insect native to southeast Asia. In addition
to being annoying, the pest is a serious concern because it feeds on field crops
like soybeans and a number of vegetable crops and ornamentals. It can also attack
crops that produce fruit, like peaches, cherries, pears and crabapples. The insect
is very mobile, adaptable to different ecosytems and restistant to most common
urged to finalise ballast water's invasive species rules (Nov
World Fishing & Aquaculture.
The World Ocean Council, shipping, fisheries, aquaculture, and desalination industries
have called for an urgent ratification of the Ballast
Water Convention. To control the spread of marine invasive species through ballast
water, governments approved an international treaty in 2004, but the global
regulations are still not in force due to the lack of a few government ratifications.
Locks up West Nile's Infection Mechanism
(Nov 2, 2010)
Researchers have learned the structure that results when an antibody binds to
the West Nile virus, neutralizing the
virus by locking up its infection mechanism. The information could help scientists
develop a vaccine against the mosquito-borne disease.
