Invasive plants on UAF Campus mapped
University of Alaska Fairbanks senior Jessica Guritz mapped invasive plants on the UAF campus this summer as an integrated pest management technician. Her work, a joint project of the Cooperative Extension Service and the U.S. Forest Service, identified 14 invasive species that volunteers will evict. The final product of her work is a series of aerial photos showing the locations and densities of these species and a report. She worked under the direction of Extension agent Michele Hebert. Says Guritz, "It has been a great experience working on this project and I encourage others to join the battle against invasive plants in Fairbanks!"

RECALL OF PRODUCTS FROM SCOTTS CO.
"The Alaska Department of Environmental Conservation has issued two recalls of Scotts Co. brand products found to be in violation of EPA regulations. Please read the following notices for details on the products, and information on returning the products.
Calling it a serious violation of its system for protecting public health, the U.S. Environmental Protection Agency (EPA) ordered Scotts Miracle Gro Company and its affiliates on April 14, 2008 to stop selling certain pesticides because they are not properly registered and labeled."

"The U.S. Environmental Protection Agency has ordered The Scotts Company to stop selling and distributing an additional two lawn and garden pesticide products that were not properly labeled. The U.S. EPA has concluded that the Scotts products are mislabeled/misbranded resulting in an immediate cancellation of EPA registrations for both subject products. Pesticide products must be registered with the EPA and ADEC to protect public health and the environment before they can be sold in Alaska. The EPA registration process provides consumers with assurance that the products are safe when used in accordance with instructions on labels "

EPA Draft Effects of Climate on Aquatic Invasive Species (AIS) and Implications for Management and Research (EPA-HQ-ORD 2007-0666)

Summary:
This draft report addresses the potential effects of climate change on Aquatic Invasive Species (AIS) and consequences for their management, and describes apparent research gaps. The report is intended for managers and scientists working with AIS to provide them with information on the potential effects of climate change on AIS, strategies for adapting their management to accommodate these environmental changes, and highlight further research needs and gaps. The literature review that introduces this report shows that important progress has been made in identifying climate change effects on invasive species, but that our understanding of effects on specific species and interactions of other stressors needs to be improved. Following the literature review is an analysis of existing AIS management plans to assess the capacity of states to modify or adapt their management activities to account for climate change effects. The assessment shows that most states currently do not explicitly consider climate change in their aquatic invasive species management plans, but that many plans can incorporate new information on changing environmental conditions. Finally, this report compares information needs of AIS managers with current research to determine where gaps exist. Overall, more information and research are needed on many aspects of the effects of climate change on AIS.

Campers asked to leave firewood at home

CONCORD, N.H. (AP) As millions of Americans pack for their first camping trips of the season this weekend, foresters hope they will leave one thing behind: firewood.

The U.S. Forest Service and state forestry agencies around the country say transporting firewood lets tree-killing insects hitch a ride into the woods, contributing to billions of dollars in damage and needless work each year. "While some insect species might spread 40 miles in a year by natural migration, a person hauling infested firewood from home to camp could move a species hundreds of miles in a single day. It's like making the jump to light-speed for the bug," said Bernie Raimo, the Forest Service's forest health group leader in the Northeast. Officials advise campers to get firewood at or near their destinations instead....

Outbreak of Vibrio parahaemolyticus Gastroenteritis Associated with Alaskan Oysters
New England Journal of Medicine article (.pdf)

Article summary (Lisa Ka'aihue, PWSRCAC):
"A recent example of potential invasive species impact occurred during the summer of 2004. Oyster farmers in Prince William Sound suffered an outbreak of human illness caused by Vibrio parahaemolyticus (Vp). One farm was implicated in the outbreak of 62 confirmed cases, making this the first incident of Vp in the state and the second largest outbreak in United States history. Although this outbreak is still under investigation, the O6:K18 isolate is similar to that found in Puget Sound, and the researchers have not ruled out the possibility that it may have resulted from a ballast water invasion. As long as Prince William Sound keeps receiving vast amounts of untreated ballast water, and continues to experience rising water temperatures in Alaska due to global warming, more such incidents are very likely."

Atlantic salmon caught in Cook Inlet traced to Washington
HATCHERY: First ever in Inlet, but hundreds picked up in Alaska.

KENAI -- An Atlantic salmon caught near Kasilof in July had escaped from a private hatchery in
Washington state, according to state wildlife officials.

The fish was the first documented Atlantic salmon in Cook Inlet, but the origin of the fish
remained unknown until lab tests focused on its otoliths -- small, rounded bonelike structures
found in the inner ears. The structures develop unevenly depending on the fish's growth rate,
forming rings like those akin to tree rings.

The fish found off Cohoe Beach had very even growth rings, indicating it had received regular
feedings, like salmon raised in hatcheries and farms, according to Bob Piorkowski, invasive
species program coordinator for the Alaska Department of Fish and Game.

With the help of the Washington Department Fish and Wildlife, the Alaska agency determined
the fish had likely escaped from a private hatchery near Scatter Creek in Rochester, Wash.

While inspecting the otoliths, Fish and Game discovered what is called a thermal mark,
meaning it had been briefly exposed to higher than normal temperatures that leave a
distinguishing mark on otoliths. Washington requires Atlantic salmon raised in state waters
to undergo such marking to help in identification should a fish escape.

Piorkowski said the mark found on the otolith could have been caused by something other
than the thermal exposure, but it is unlikely.

The Washington hatchery's last major escape occurred in spring 2005 when 4,500 one-
pound fish were released, Piorkowski said. A hatchery official said, however, the salmon
found in Cook Inlet likely escaped in May when fish were loaded onto a transfer barge,
Piorkowski said.

Atlantic salmon can jump higher than Pacific salmon.

Alaska prohibits raising farmed Atlantic salmon, but nearly 600 specimens of the species
have been documented in state waters. One out of every 100 Atlantic salmon raised on fish
farms in British Columbia and Washington escapes, according to Piorkowski.

The concern for many is that Atlantic salmon could spoil native salmon stocks through
colonization, interbreeding, predation, habitat destruction and competition.

Opposing effects of native and exotic herbivores on plant invasions.
Science 311:1459-1461

ABSTRACT
Exotic species are widely assumed to thrive because they lack natural enemies in their new
ranges. However, a meta-analysis of 63 manipulative field studies including more than 100
exotic plant species revealed that native herbivores suppressed exotic plants, whereas exotic
herbivores facilitated both the abundance and species richness of exotic plants. Both
outcomes suggest that plants are especially susceptible to novel, generalist herbivores
that they have not been selected to resist. Thus, native herbivores provide biotic resistance to
plant invasions, but the widespread replacement of native with exotic herbivores eliminates
this ecosystem service, facilitates plant invasions, and triggers an invasional "meltdown."
