Register New Lampricide Active Ingredients and End-use Formulations and Maintain Registered Products in Compliance with United States and Canadian Pesticide Regulations
The USGS Upper Midwest Environmental Sciences Center (UMESC) provides regulatory affairs assistance to the Great Lakes Fishery Commission (GLFC), U.S. Fish and Wildlife Service (FWS), Department of Fisheries and Oceans Canada (DFO), state and private partners in matters regarding numerous registrations of the lampricides TFM and niclosamide in the U.S. and Canada. The result of this technical...
Residue Levels of the Lampricides TFM and Niclosamide in Moribund Sea Lamprey Larvae Following Exposures to TFM and a TFM/1% Niclosamide Combination
Concerns regarding the exposure of wildlife to TFM and niclosamide that would result from the consumption of sea lamprey (Petromyzon marinus) larvae exposed to these chemicals has prompted a need to investigate uptake of these chemicals in larval lampreys. A study to address concerns regarding the exposure of the endangered common term during the treatment of the St. Marys River was completed in...
The Lethality of Hot Water and Ozone on Aquatic Invasive Species
With the increasing prevalence of Aquatic Invasive Species (AIS) in the Chicago Area Waterways System (CAWS), the implementation of new control techniques to inhibit the dispersal of AIS is strongly desired. For a technique to be a truly viable option, the process would inhibit the movement of AIS between the Mississippi River Basin and the Great Lakes. A physical barrier separating these regions...
Species Distribution Modeling
A requirement for managing a species, be it a common native species, a species of conservation concern, or an invasive species, is having some information on its distribution and potential drivers of distribution. Branch scientists have been tackling the question of where these types of species are and where they might be in the future.
Restoration Ecology
Restoration of ecological systems in wildland areas often involves restoring species to habitats degraded by invasive plant and animal species. Often, such invasive species exert community level impacts, such as direct competition, but may also alter ecosystem function. For example, invasive plants have been documented to alter fire regimes, soil nutrients and microbes, food webs, and/or...
Optimal Control Strategies for Invasive Exotics in South Florida
The establishment and proliferation of exotic plants and animals can interfere with native ecological processes and can cause severe stress to sensitive ecosystems.
