Watch out for wandering crayfish!

This short video shot near Chicago was posted a few weeks ago on youtube, and it shows the remarkable ability of crayfish to traverse land in search of a new aquatic home. It's no wonder that crayfish are among the most successful aquatic invasive species in many parts of the world - their ability to invade new habitats by traversing through grasslands, fields and or other terrestrial areas makes them an ideal candidate for invasion. Can you imagine if all aquatic invaders had such an ability??!

Lunch?

Check out Invasivore.org, a site devoted to the notion that one of the best features about invasive species is the sense of retribution we can get for the harm they do to ecosystems when we eat them.

After all, whether a crayfish is native or introduced makes no difference to how it tastes.

Craywatch on the road: Ecology Society of America 2011

The 96^th annual meeting of the Ecological Society of America is on now in Austin, Texas, and Craywatch is here! I’ll be presenting and talking a little bit about the Craywatch project. It will be in Auston Convention Center room 13 at 9:00 am on Tuesday, 9 August.

I’ll also be presiding over the session, Predator-Prey Interactions I. I think it only fair to warn any presenters in that session:

• Don’t you dare go over time.
• Don’t you dare have Comic Sans in your slides. I will name and shame on my blogs!

Please stop by and say hi! Follow the meeting by searching for #esa11 on Twitter.
