Alien invaders

Alien invaders

Thousands of species have invaded new territories in recent decades, often aided by global trade and man-made habitat change. While many remain harmless, some may cause serious damage. Therefore, we need improvements in surveillance and in our understanding of which factors make a successful invasion possible.

Co-invaders: The effects of alien parasites on native hosts

We define co-introduced parasites as those which have been transported with an alien host to a new locality, outside of their natural range, and co-invading parasites as those which have been co-introduced and then spread to new, native hosts. Of 98 published studies of co-introductions, over 50% of hosts were freshwater fishes and 49% of parasites were helminths. Although we would expect paras...

Impact of Alien Plant Invaders on Pollination Networks in Two Archipelagos

Mutualistic interactions between plants and animals promote integration of invasive species into native communities. In turn, the integrated invaders may alter existing patterns of mutualistic interactions. Here we simultaneously map in detail effects of invaders on parameters describing the topology of both plant-pollinator (bi-modal) and plant-plant (uni-modal) networks. We focus on the invad...

Space invaders

all in the nation’s opinion-leading newspapers — the New York Times, Washington Post or Los Angeles Times. (The New York Times did mention it in a blog.) My network, National Public Radio, interviewed David O’Brochta from the University of Maryland’s Biotechnology Institute — who spoke about the work even though he wasn’t an author of the paper. The Associated Press wire service also produced a...
