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.

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.
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 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.
Queen's University Belfast (United Kingdom).
Research led by Queen’s University Belfast has shown that invasive species, such as the grey squirrel, European rabbit and Japanese knotweed, have cost the UK economy over £5 billion over the past 40-50 years. This is one of the highest totals in Europe. Invasive species, those introduced and spreading outside of their native range as a result of human activities, are a growing threat to environments worldwide. Environmental impacts of invasive species, one of the main causes of biodiversity loss, are well-studied. However, few studies have summarised their economic impacts. This study is the largest and most up-to-date combination of economic costs of biological invasions in the UK. The results have been published in the journal NeoBiota.

Since arriving to the northern Atlantic Ocean less than 30 years ago, lionfish have quickly become one of the most widespread and voracious invasive species, negatively impacting marine ecosystems—particularly coral reefs—from the northeast coast of the United States to the Caribbean Islands. In a new study, an international research team including the California Academy of Sciences presents four new records of lionfish off the coast of Brazil, confirming the invasion of the predatory fish into the South Atlantic for the first time.
The environmental tolerances and potential range of the tomato pest Tuta absoluta in Africa, the Arabian Peninsula, Central Asia and Australia may have been underestimated according to new research co-authored by CABI scientists. All results from the scientists' research suggests with the greatest certainty that T. absoluta (also known as Phthorimaea absoluta or tomato leafminer) has further to spread globally, particularly in southern and East Asia, Australia and Central America.

White-nose syndrome has killed over 90% of northern long-eared, little brown and tri-colored bat populations in fewer than 10 years, according to a new study published in Conservation Biology. Researchers also noted declines in Indiana bat and big brown bat populations. The findings, detailed in "The scope and severity of white-nose syndrome on hibernating bats in North America," underscore the devastating impacts of the deadly fungal disease. The research tapped into the most comprehensive data set on North American bat populations to date, which includes data from over 200 locations in 27 states and two Canadian provinces.
