High-speed Sprint Speed

I’ve posted in the past about the lizard sprint speed studies I’ve tried over the years on erhardii. Each of those experiments have come with the caveat that without a high-speed camera (shooting around 500 frames per second and costing the down-payment for a house) we can’t detect more subtle differences between lizard populations. Well, this year … More High-speed Sprint Speed

Working on the islands

So the primary goal this year was to walk the islands and catch as many of the remaining lizards as possible. With a complete census of the population, we can start getting awesome data on natural selection’s “filters” dictating survival of the fittest. Even better, by taking careful measurements of the survivors we can figure out … More Working on the islands

The islands revisited

After several “are you still alive?” emails yesterday I think it’s time to update the blog! I’m sorry for the delay, but it was for good reason: this last week has been non-stop revisiting of the five introduction islands from last year. I’m going to stretch this out over several posts because it was a lot of work and the … More The islands revisited

Visiting the Paros Islets

One of the big goals for this summer’s research is to initiate a long-term island-manipulation experiment on small islets near Naxos and Paros. The logistics and permitting for the experiment have been far more difficult than I’d anticipated, but while I am working with collaborators and government officials to finalize the plans, the first priority was determining whether the dozen islands I’d … More Visiting the Paros Islets

Fishing for lizards

There are lots of ways to catch a lizard. The low-tech solution of course is the old ‘lift a rock and smash your hand down on anything that moves’ method. I tend to prefer more delicate techniques though, particularly in deference to the vipers that also make their homes under these rocks. So if it’s … More Fishing for lizards

Greece Wrap-up

As per normal, the field season in Greece finished at a sprint and I fell (way) behind on keeping up with the stories. Sorry! I’m going to back-date a few posts to get you all up to speed. All in all, the summer was a great success – I collected nearly all the data I … More Greece Wrap-up
