New (or old?) mode of transport for invasive species

– October 4, 2017

Carlton et al. Science 29 Sep 2017:

”..We document 289 living Japanese coastal marine species from 16 phyla transported over 6 years on objects that traveled thousands of kilometers across the Pacific Ocean to the shores of North America and Hawai‘i. Most of this dispersal occurred on nonbiodegradable objects, resulting in the longest documented transoceanic survival and dispersal of coastal species by rafting…”

The more I study invasive species the more I realize how little I (we?) know about them: they can adapt to a new habitat relatively easily, they successfully compete with native species, they disperse fast, and apparently long distance is also not an obstacle for them!
