Evolution makes invading species spread even faster
Today, invasive animals and plants spread all around the globe. Predicting the dynamics of these invasions is of great ecological and socioeconomical interest. Yet studying them is fundamentally challenging ...
Genetics provides new clues about lionfish invasion
New genetic data suggest the red lionfish invasion in the Caribbean Basin and Western Atlantic started in multiple locations, not just one as previously believed, according to a new study led by the U.S. Geological Survey.
Grey squirrels' role as hosts of Lyme disease bacteria under the spotlight

Unresolved composition of Lantana camara: Impediment to its management
A group of plant invasion ecologists from University of Delhi, India have highlighted the need to disentangle the composition of the highly variable Lantana species complex in order to facilitate management effort ...
Florida lizards evolve rapidly, within 15 years and 20 generations
Scientists working on islands in Florida have documented the rapid evolution of a native lizard species—in as little as 15 years—as a result of pressure from an invading lizard species, introduced from ...
Invasive species use landmarking to find love in a hopeless place
Tiny populations of invasive species such as Asian carp start their domination of new ecosystems by hanging out at local landmarks, according to a new study published in the journal Theoretical Ecology this w ...
Preventing the spread of aquatic invasive species
Hot water could be the answer to stopping aquatic invasive species from "hitchhiking" around Britain on anglers' and canoeists' kit, according to a new study.
