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.

White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

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.

Great Lakes Commission.

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 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.

Northeastern Integrated Pest Management Center. IPM Insights (June 2021: Volume 18, Issue 1).

The National Integrated Pest Management Coordinating Committee (NIPMCC) has released a series of whitepapers explaining how pests threaten the security of the U.S. food supply, how an IPM approach offers the most effective means of managing pests, and why ongoing investment in IPM research and extension is critical to keeping pace with the ever-evolving nature of these threats. These new issue papers discuss role of IPM in combating resistance and invasive species, safeguarding food supply, and minimizing economic losses.

Forest Service scientists have published a guide synthesizing best practices for controlling these tiny bugs. It promotes a strategy of combining insecticide use with adelgid-eating insects.

There is growing concern that changing climate conditions will amplify the negative impacts of non-native invasive species and facilitate their expansion. Despite the potential ecological and economic impacts of invasive species expansions in the Northwest, there has been no comprehensive synthesis on climate change effects on invasive species – until now. NW CASC-funded researchers Jennifer Gervais (Oregon Wildlife Institute), Clint Muhlfeld (U.S. Geological Survey) and colleagues conducted an extensive literature analysis to determine the current state of knowledge about climate change effects on non-native invasive species in the Northwest.

Interactions between invasive species and climate change present new challenges for resource management. Prior to a new study by NE CASC fellow Evelyn Beaury and her collaborators, however, it was unclear what the common concerns, strategies, limitations, and research needs were for managing invasive species in a changing climate. In their nationwide survey of invasive species managers from government, non-profit, and private organizations, Beaury's team found that while the majority of managers are very concerned about the influence of climate change on invasive species management, the organizations they represent are typically far less engaged with this issue. This study illustrates that the complicating challenge of climate change may open a new avenue for elevating the efficiency and success of current invasive species management efforts if a collaborative approach is adopted in this area.

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch. The research, appearing online in the journal Biological Invasions, is based on a new model that simulates interactions between the bigheaded carps and a range of fish species, including walleye, yellow perch, and groups lower on the food web over a time period of 50 years. Over 180 non-indigenous aquatic species have already become established in the Great Lakes, with a handful of these producing substantial negative impacts. While bigheaded carps are established in watersheds near the Great Lakes, they have not yet become established in the Great Lakes.
