Rising global temperatures may be magnifying the threat of invasive species, according to researchers from Dartmouth College and the University of Wisconsin, Madison.
In a study published in Ecology earlier this month, Samuel Fey and Christina Herron examined the effect of elevated temperature on population dynamics in a system inhabited by a invasive species.
Invasive species tend to thrive in ecosystems by competing with similar native species for resources. Because invasive species have not evolved alongside the system's top predators (a phenomenon known as antagonistic evolution), they are generally not recognized as particularly attractive prey. Thus, these species grow unchecked, draining resources, crowding out competitors and offsetting the ecosystem.
