Researchers in California have discovered an interplay between 3 species – due to invasive mice on the Farallon Islands are causing migrating burrowing owls to remain on the islands to eat them. But when the mice population crashes, they switch to preying upon the endangered ashy storm-petrel.
The first global meta-analysis of the characteristics and size of invasive alien species’ impacts on native species as invaders become more abundant has been conducted. The study highlights the increasing need for early detection and rapid response.
An in-depth study of the northern spotted owl has examined its decline in the Pacific Northwest of the United States. Removal of the invasive barred owl may be one solution, in combination with long-term protection of its habitat.
The eradication of invasive rats on the remote Pacific island Palmyra Atoll has led to positive benefits for native trees and the many other species who live in this habitat.
Researchers have discovered why the brown tree snake has become such a successful invasive species on the island of Guam, where it has devastated native bird populations.
Pine martens are making a comeback in Scotland, which is suppressing populations of the invasive grey squirrel – this in turn is helping the recovery of the native red squirrel.
A new study has stressed the need for more species to be urgently considered for inclusion on the European Union’s ‘List of Invasive Alien Species of Union Concern’, due to their potential impact on native species and ecosystems.
As invasive species are threatening ecological habitats throughout North America, the role of Indigenous nations as environmental stewards has been overlooked, according to a new study.
The brown tree snake is an invasive species on Guam, and has exterminated many forest bird species. Without the birds to disperse seeds, the indirect impact of this has been to negatively affect the regeneration of trees on the island.
Conservationists have collected hundreds of amphibian species threatened by the fungus and are maintaining them in captivity with the hope to someday re-establish them in the wild.
