The Camargue area in France has now a lot less grasshopper, cricket, locust, dragonfly, and amphibian species than 40 years ago. On the other hand, there are more birds and vascular plants, some of them considered as new and highly invasive species.
A remote island in the Caribbean could offer clues as to how invasive species are able to colonise new territories and then thrive in them, a new study suggests.
That is the conclusion of a study tracking research, fishing and tourist vessels that routinely visit the protected, otherwise isolated region.
