A tiny shellfish showed up uninvited in California and started spreading before anyone knew what it was. Now the federal government is paying to stop it.

As Alaska’s rivers warm, invasive northern pike are becoming noticeably more voracious. Scientists discovered that pike of all ages are eating more fish, with young pike increasing consumption by over 60%. Warmer water speeds up their metabolism, pushing them to hunt more. This growing appetite could spell trouble for struggling salmon populations.

April 23, 2026 Shellfish growers have long been stewards of Washington’s rich marine waters. After all, the industry as a whole relies on healthy marine ecosystems. So it probably comes as no surprise that shellfish growers have been partners in efforts to control invasive European green crab from the get-go. It has been routinely observed that green crab aggregate around aquaculture gear, partic…

A better understanding of what happens belowground when restoring coastal vegetation may be useful to better plan restoration. However, little is known about what happens belowground when invasive species are controlled in restoration settings. My students and I used a protected area of sandy coastal vegetation in an island in Southern Brazil as a model to investigate belowground dynamics in plan…

Alien species are giving freshwater ecosystems in Africa and beyond a mauling. But a new project, backed by funding from one of the continent’s premier prizes for young researchers, holds hope. The post From ponds to power plays: South African scientist tackles invasive plants with game-changing research appeared first on Research and Conservation .

Shortlisted for the 2024 Southwood Prize Agostina Torres introduces us to her latest research which evaluated the dependence of community reassembly on inverse priority effects by experimentally removing the target invasives in field and mesocosm communities. About the research Overview The study emerged as part of my PhD doctorate. Along with my supervisors, Drs. Martin Nuñez and Mariano Rodrigu…

Author Sarah Kingsbury shares a new integrated management approach to better assess the effects and risks of aquatic invasive species on Atlantic salmon in Nova Scotia, Canada. Invasive species played key roles in the extinction of 60% of Earth’s plants and animals as reported by IPBES in 2023. While not all alien species introduced to new habitats become problematic (or even are able to establis…

In this new post, Hao Liu—a postdoc from Fudan University, China—presents his work ‘Root plasticity benefits a global invasive species in eutrophic coastal wetlands’. Here he discusses the importance in plasticity for invasive species success, highlights the cohesion required to work in the mud, and shares his journey in ecology. About the paperInvasive species usually benefit more than native sp…

Trevor Caughlin and co-authors describe how the local impacts of an invasive plant motivated research to understand where it spreads. Biological invasions threaten global biodiversity, motivating studies to control invasive species’ spread. We studied outbreaks of puncturevine (Tribulus terrestris), an invasive species in Western North America. While our team appreciates the global threats …

Cogongrass is an aggressive weed that is rapidly spreading across Alabama and the Southeast. Learn important steps you can take to slow the spread of this environmental invader. Cogongrass (Imperata....

This blog post is provided by Allan McDevitt and Samuel Browett and tells the #StoryBehindthePaper for the paper “Resource competition drives an invasion-replacement event among shrew species on an island”, which was recently published in Journal of Animal Ecology. In their paper they determine how a recently invading shrew is outcompeting a native shrew for prey resources, ultimately leading to …

Trevor Renals is the senior technical advisor on invasive species for the Environment Agency. He started his career working on Japanese knotweed management in his native Cornwall, which led to an interest in biological control solutions, using co-evolved natural enemies of invasive species to manage biological invasions instead of widespread herbicide applications. He has over 30 years’ experienc…

Asian Carp Kevin Rose | Smithsonian Environmental Research Center Asian Carp is a common name usually used to describe several species of invasive fish in the U.S. Typically, this includes black carp (Mylopharyngodon piceus), bighead carp (Hypophthalmichthys nobilis), and silver carp (H. molitrix). Occasionally, grass carp (Ctenopharyngodon idella) is also considered an invasive species of Asian …

Two newly published research studies from the U.S. Geological Survey show that, depending on their size and body condition, invasive tegu lizards from South America could survive in cooler, northern climates.

It’s not unusual to see invasive species growing along roadside, in woodlots, and backyards all over Alabama. The mimosa or silk tree (Albizia julibrissin) is one of the invasive species....
