Garbage and invasive species

My friend Rebeka has written a guest post about invasive species for the Marine Debris Blog. I hadn’t realized that garbage dumped into the oceans was an important vector for the propagation of such species.

Invasive species are a topic of considerable global relevance. There are the Asian carp that people are working hard to keep out of the Great Lakes, for instance. There is also the rather large question of what sort of inter-ocean migrations will occur as the result of the loss of summer sea ice in the Arctic. If orca whales migrate into the Atlantic (as Alun Anderson predicts), life will become rather more dramatic for a lot of seals in Newfoundland. Shipping is one major mechanism through which species from one place can end up in another, where they cause ecological problems.

When I worked at the Science Al!ve daycamp at Simon Fraser University, I remember one ecology graduate student who was waging a dedicated campaign against a particular invader: the black licorice slug (Arion rufus). She used to put them in her pockets when she found them and then throw them into ponds when the opportunity arose.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
