Extinction (or lateral transfer?)

Extinction (or lateral transfer?)

This has been coming for a while, but I needed a push to make it official. I’m not much of a blogger anymore (four posts a year doesn’t quite cut it), so it’s only fair that I wrap things up at SciAm Blogs, at least for the foreseeable future.

Greetings from Halifax, a world centre of protistology!

I finally made the move I was supposed to do months (if not years) ago! Through a strange twist of evolutionary contingency (the same kind through which our kind came about in the first place), Dalhousie University in Halifax has become host to one of the worst infestations of protistologists in the world.

A Fork in the Red, 2013 (Medium: algae on glass)

This ink drawing is based on Protoperidium, a dinoflagellate notable for its ‘pallium feeding‘: upon finding something tasty but awkwardly-shaped, it extrudes a ‘feeding veil’ in the form of a pseudopod-like structure, which then envelops the prey [...]

A polyp’s pet rotifers

A polyp’s pet rotifers

Random image:

To keep things alive while I’m at an awesome conference (that you should follow on twitter, see previous post), let’s have a random image of tardigrade (water-bear) guts; the brown stuff is semi-digested food.
