Invasive Species And Climate Change, Invasive Species Advisory Committee
National Invasive Species Council
ISSUE
Climate change interacts with and can often amplify the negative impacts of invasive species. These interactions are not fully appreciated or understood. They can result in threats to critical ecosystem functions on which our food system and other essential provisions and services depend as well as increase threats to human health. The Invasive Species Advisory Committee to the National Invasive Species Council recognizes the Administration’s commitment to dealing proactively with global climate change. However, unless we recognize and act on the impact of climate change and its interaction with ecosystems and invasive species, we will fall further behind in …

Invasive Species and Public Investment in the Green Economy, approved by ISAC on June 24, 2010
ISSUE
Invasive species are intricately linked to the economy. Trade, travel, and transport facilitate their spread. Invasive species management requires extensive human and financial resources. The impacts of invasive species can substantially undermine economic growth and sustainable development. United States Executive Order (EO) 13112 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states that Federal agencies should …“not authorize, fund, or carry out actions that are likely …

National Invasive Species Council
BACKGROUND
Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler
A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler
Department of Environmental Studies: Undergraduate Student Theses
Abstract Emerald Ash Borer (Agrilus planipennis) (EAB) is an invasive insect pest. It feeds on the cambium tissues of ash tree species. It was first discovered in the United States in 2002 in Detroit, Michigan. Their effects on ash trees are deadly, and it is quickly spreading across the Midwest. Nebraska has not yet been invaded, but confirmed findings continue getting closer and closer. The major problem facing Nebraskans, with regards to EAB, is how to begin preparations to prevent a dramatic economic loss when an infestation does occur. So, to address this problem, I have conducted street and park …
Wildfire Promotes Dominance Of Invasive Giant Reed (Arundo Donax) In Riparian Ecosystems, Gretchen Coffman, R F. Ambrose, P W. Rundel
Wildfire Promotes Dominance Of Invasive Giant Reed (Arundo Donax) In Riparian Ecosystems, Gretchen Coffman, R F. Ambrose, P W. Rundel
Environmental Science
Widespread invasion of riparian ecosystems by the large bamboo-like grass Arundo donax L. has altered community structure and ecological function of streams in California. This study evaluated the influence of wildfire on A. donax invasion by investigating its relative rate of reestablishment versus native riparian species after wildfire burned 300 ha of riparian woodlands along the Santa Clara River in southern California in October 2003. Post-fire A. donax growth rates and productivity were compared to those of native woody riparian species in plots established before and after the fire. Arundo donax resprouted within days after the fire and exhibited higher …
A Modelling Approach To Evaluate Potential Management Actions Designed To Increase Growth Of White Perch In A High-Density Population, Christopher J. Chizinski, Kevin L. Pope, G.R. Wilde
A Modelling Approach To Evaluate Potential Management Actions Designed To Increase Growth Of White Perch In A High-Density Population, Christopher J. Chizinski, Kevin L. Pope, G.R. Wilde
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
A deterministic, age-structured population model was developed to simulate potential management scenarios designed to increase growth of individuals (quantified by maximum length) in a hypothetical population of white perch, Morone americana (Gmelin). Four scenarios were developed that included non-selective mortality of adult white perch, increased mortality of age groups most influential on population growth, increased age-0 mortality and inhibiting recruitment after spawning. The greatest increase in maximum length occurred with nonselective adult mortality when population biomass was reduced by 97%; lesser increases in maximum length were achieved with the other management scenarios. Populations returned to their original state after control …
Dreissenid Mussels Are Not A “Dead End” In Great Lakes Food Webs, Charles P. Madenjian, Steven A. Pothoven, Philip J. Schneeberger, Mark P. Ebener, Lloyd C. Mohr, Thomas F. Nalepa, James R. Bence
Dreissenid Mussels Are Not A “Dead End” In Great Lakes Food Webs, Charles P. Madenjian, Steven A. Pothoven, Philip J. Schneeberger, Mark P. Ebener, Lloyd C. Mohr, Thomas F. Nalepa, James R. Bence
United States Department of Commerce: Staff Publications
Dreissenid mussels have been regarded as a “dead end” in Great Lakes food webs because the degree of predation on dreissenid mussels, on a lakewide basis, is believed to be low. Waterfowl predation on dreissenid mussels in the Great Lakes has primarily been confined to bays, and therefore its effects on the dreissenid mussel population have been localized rather than operating on a lakewide level. Based on results from a previous study, annual consumption of dreissenid mussels by the round goby (Neogobius melanostomus) population in central Lake Erie averaged only 6 kilotonnes (kt; 1 kt=one thousand metric tons) …

Evaluating Commercially Available Rodenticide Baits For Invasive Gambian Giant Pouched Rats (Cricetomys Gambianus), Gary W. Witmer, Nathan P. Snow, Patrick W. Burke
United States Department of Agriculture Wildlife Services: Staff Publications
Gambian giant pouched rats (Cricetomys gambianus) are native to Africa, but they are popular in the pet industry in the United States. They were reservoir hosts during a monkeypox outbreak in the Midwestern United States in 2003. A free-ranging population became established on Grassy Key in the Florida Keys, apparently because of a release by a pet breeder. These rodents could cause significant damage to agricultural crops should they reach the mainland. Research under controlled conditions was needed to identify effective rodenticides for Grassy Key or other cases where an invasion of Gambian rats might occur. We tested …
