Native freshwater mussels grew more slowly when invasive Asian clams (Corbicula fluminea) were abundant. The study was led by Wendell Haag, a USDA Forest Service research fisheries biologist. It was published in the journal Freshwater Biology. Mussels live out of sight – buried in the river bottom, eating algae and other small particles of organic material. Mussels are filter feeders and key members of aquatic ecosystems. Unfortunately, mussels are disappearing worldwide, and about 70 percent of the 300 mussel species native to the U.S. are in danger of extinction. Addressing mussel declines is difficult because their causes are mostly unknown.

Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

Farmers who grow cereal crops in most African countries are all too familiar with the challenges presented by striga, a parasitic plant also known as witchweed that infests farmers’ fields and causes lower yields, or even no harvest at all. Now African scientists are breeding maize that can resist this pest plant as extension agents are offering farmers various solutions for improving yields in areas where the invasive weed is especially prevalent.

A cozy campfire for summer days, a warm fireplace for winter evenings– the use of firewood is an "established cultural norm". However, moving firewood from place to place can have devastating consequences, as it can spread forest pests that decimate forests to collectively cost an estimated $4.2 – $14.4 billion per year. In order to better address the problem of people moving firewood and vectoring forest pests, Solano and colleagues examined trends and gaps in the existing literature on firewood and human-mediated forest pest movement in North America. The existing literature demonstrates the risk of firewood movement, but fails to address the level of awareness the public has on such risks, or the level of effectiveness of firewood regulations to prevent forest pest spread.

GLOBAL: Globodera Alliance.
GLOBAL is a five-year $3.2 million project funded by USDA. The project title is "Risk assessment and eradication of Globodera spp. in U.S. production of potato", with research focused on the potato cyst nematodes Globodera pallida (pale cyst nematode), G. rostochiensis (golden nematode), and the related species G. ellingtonae that has recently been found in Oregon and Idaho. GLOBAL stands for "Globodera Alliance", a group of 17 research, extension, and education professionals, located in Idaho, Oregon, New York, Canada, Scotland, and France. GLOBAL members include faculty from the University of Idaho, Oregon State University, Cornell University, US Department of Agriculture (USDA), Agriculture and Agri-Food Canada, The James Hutton Institute, and the French National Institute for Agricultural Research.

The Great Lakes Phragmites Collaborative is a network of agencies, organizations and citizens who are engaged in Phragmites in some way, including management, research and communication. The Collaborative was established to facilitate communication among stakeholders across the region and serve as a resource center for information on Phragmites biology, management, and research.

See also: Phragmites Adaptive Management Framework (PAMF) Strategic Plan (2020-2026). This strategic plan will guide successful implementation of PAMF by setting program-specific goals, objectives, and measures for the next five years. The PAMF core science team that developed the plan includes representatives from the Great Lakes Commission, U.S. Geological Survey, and University of Georgia.

The Asian tiger mosquito can carry dread diseases like Zika, and yellow and dengue fever. After it vanished from Palmyra Atoll, an island in the tropical Pacific, USGS researchers and partners set out to find out why.

The green crab, Carcinus maenas, is a widely distributed invasive species that eventually alters its new environment. It's assumed that such species have high genetic diversity, or a variety of characteristics allowing them to adapt and thrive. But the green crab has low genetic diversity, while still spreading rapidly in a new part of the world. A U.S. National Science Foundation-funded study led by Carolyn Tepolot of the Woods Hole Oceanographic Institution is investigating the adaptive mechanisms of the green crab along the west coast of North America, where it has shown extensive dispersal in the last decade despite minimal genetic diversity. The results are published in Molecular Ecology. The project is a collaboration among scientists at WHOI, Portland State University, the Smithsonian Environmental Research Center and the University of California, Davis.
