Lizards on small islands bite harder than lizards on big islands… and why!

This Fall, one of my big data-driven dissertation chapters was published in Functional Ecology. The paper is called “Feed or Fight: Testing the impact of food availability and intraspecific aggression on the functional ecology of an island lizard.” Long story short: we found that lizards on small islands were larger than lizards on big islands. … More Lizards on small islands bite harder than lizards on big islands… and why!

Islands from Zas

Mt. Zas is the tallest mountain on Naxos, and the highest point in the Cyclades. On a clear day you’re supposed to be able to see over two dozen surrounding islands. Well, last week we finally got that clear day. Even luckier, my brother was along with his camera and he snapped these awesome pictures. First … More Islands from Zas

Old Maps

Sorry for the delay in posts. I was working through the data from the island manipulation experiment to share with you, but analysis started getting complicated and then I got busy getting engaged. Hurrah! I’m in the last field research push though so I’m going to try to post several updates over the next two weeks while I’m still in Greece. The first … More Old Maps

PIT Tagging Lizards

A critical component of this study is being able to keep track of who is who, every single year. There are a lot of tried and true methods for doing so, including the low-tech of removing the last joint of different combinations of toes. There’s the mid-tech: injecting multi-colored liquid plastic that congeals just under the skin to give … More PIT Tagging Lizards

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

Still more videos

It’s been weeks since my last post (sorry) but for better or worse the topic of this post is about the same: lizard videos. For the last two months I’ve spent far too much time pouring over videos of lizards running up and down sprint speed tracks, basking on rocks, or dashing under bushes. Luckily, occasionally I … More Still more videos
