Species Awareness Week to Focus on Harmful Nonnative Species (Feb
23, 2011) / National Invasive
Species Awareness Week 2011 -- Feb 28-Mar 4, 2011
Weed Science Society of America; National
Invasive Species Awareness Week.
A broad coalition of stakeholders will gather next week to spotlight harmful
invasive species that cause a multibillion-dollar annual drain on our nation's
economy. A week of activities, briefings, and events in Washington D.C. to highlight
what is being done across the nation and around the world to stop and slow the
spread of invasive species. See Schedule
of Events (PDF | 416 KB) and USDA and Invasive Animal
and Pathogen (ITAP) Day (PDF | 203 KB)
Smart Against Invasive Species
Invasive Species Program.
'Playing Smart Against Invasive Species' videos produced by the USDA Forest
Service are excellent resources for education and public outreach. These videos
explain how people can enjoy the great outdoors and avoid spreading invasive
species along the way. Videos ranging from 6-27 minutes targets outdoor recreational
users and includes camping, horseback riding, canoeing, snowmobiling, cross-country
skiing, biking, and others.
Flowers Are Pest Free on Valentine's Day (Feb
Customs and Border Protection.
During the weeks leading to Valentine's Day, U.S. Customs
and Border Protection’s highly trained agriculture specialists have been
ensuring that plant diseases and plant pests are detected and prevented from
being introduced into the U.S. where
they could cause harm.
of Genes and Proteins in Asian Soybean Rust Resistance Emerging (Feb
USDA. Agricultural Research Service.
Asian soybean rust, caused by the
fungus Phakopsora pachyrhizi, is a disease of soybean crops worldwide,
causing yield losses of 10 to 80 percent. Detection of the disease on the U.S. mainland
in 2004 has prompted an intensive effort to improve resistance for America's
$30 billion soy crop. Two teams of ARS and
university scientists have discovered new information about the mechanisms of
resistance in some soybean plants to the fungus Phakopsora pachyrhizi.There
are five known genes conferring resistance, but none of those genes are currently
present in the U.S. crop, and their
roles in regulating the plant's broader network of genes and proteins necessary
to achieve resistance are poorly understood. Piecing together this molecular
mosaic could reveal defense responses that could be amplified, either through
breeding or biotechnological means. The research is published in the Molecular
BioSystems article Nuclear proteomic
changes linked to soybean rust resistance.
WSSA Applauds USDA Funding
of Vital Weed Science Research (Feb 8, 2011)
Weed Science Society of America.
The Weed Science Society of America applauded a decision by the USDA to
fund vital research involving the management of weeds and invasive plants. USDA's
National Institute of Food and Agriculture (NIFA) has budgeted $23 million for
competitive grants during 2011 in the Foundational Program area of plant health
and crop production, including weed management. See Agriculture
and Food Research Initiative Competitive Grants Program (PDF | 510 KB) for
Ecology Network Created by U of M (University of Minnesota) Researchers
Overturns Assumption about Invasive Plant Species (Feb
University of Minnesota.
Invasive plant species are a serious environmental, economic and social problem
worldwide. Their abundance can lead to lost native biodiversity and ecosystem
functions, such as nutrient cycling. New research using the global ecology network, Nutrient
Network has overturned the common assumption that many invasive plant species
behave more aggressively in new habitats than in their own. Instead, results
indicate that invasive plants have a similar or lower abundance in new and native
ranges, and that increases are unusual. The findings are published in the Ecology
Letters article Abundance
of introduced species at home predicts abundance away in herbaceous communities.
The research is funded by the National Science Foundation; for more information

and Away: Are Invasive Plant Species Really That Special?
