Antarctic Blast

Reuters is out with a report on the burgeoning problem of invasive species in Antarctica. The piece has more meat to it than the BBC report on the same subject from back in 2006, with Reuters listing several examples of introduced species and delving into the restrictions that are placed on those who visit in an attempt to protect our most southern of continents. Definitely worth a read.

Man, That's Cold

BBC News is reporting on the growing concern among scientists that the Antarctic is currently vulnerable to rising numbers of invasive species. At the recent Antarctic Treaty Consultative Meeting in Edinburgh, Scotland, scientists noted that an increase in human contact along with climate change is making the continent more susceptible than ever before to non-native plants and animals. A code of contact for visitors is currently being drafted in order to prevent future accidental introductions. Dr. Gilbert, a scientist for New Zealand's Antarctica research program, pointed out that better knowledge of the Antarctic marine ecosystem is needed in order to even begin attempting to distinguish between which species are native and which are not.

Around the World in 7 Days: Antarctica

You might be thinking that there is not much to post about invasive species in Antarctica...and you'd be right. Unfortunately last summer two scientists made a discovery that invalidated every scientific paper and newspaper article that ever said "...on every continent except Antarctica." Seems the North Atlantic spider crab (Hyas araneus) was found far from home, all way down on the Antarctic Peninsula. Read the article abstract here or read a summary on page 7, Issue 16 of the Ballast Water News (.pdf).
