Invasive species are non-native organisms that establish self-sustaining populations and spread beyond their initial introduction sites, causing or likely to cause significant ecological, economic, or health impacts. Research on invasive species examines pathways of introduction, propagule pressure, life-history traits that facilitate invasion (e.g., high reproductive rate, broad ecological tolerance), and interactions with native communities, including competition, predation, hybridization, and pathogen transmission. The topic also encompasses invasion stages (transport, introduction, establishment, spread), invasion ecology theory (e.g., enemy release, biotic resistance), risk assessment, and management strategies such as prevention, early detection, rapid response, and long-term control or eradication.
A new peer-reviewed study conducted by researchers at The University of Toledo and University of Missouri provides some of the first rigorous experimental evidence that goldfish—one of the world's most popular pets—can dramatically ...

In what is possibly another sign of climate change, mosquitoes have landed in Iceland for the first time. For many years, the island was the only Arctic country that could claim to be mosquito-free. But that all changed in ...
Birds have, for centuries, been captured from the wild to be kept in cages—valued for their looks, songs and ability to imitate sounds. Data compiled by the Convention on International Trade in Endangered Species (CITES), ...
