Agios Artemios is the final island in the bay of Naoussa and a real challenge. Take a look at the footage and keep a weather eye on the divebombing seagulls! Note: I’ve switched from hosting my videos on Vimeo to YouTube so let me know if they still work for you. Vimeo seems “slicker” but … More Meet the islands: Agios Artemios
I’m trying something a bit different this year: I bought a special cord that lets me enter a measurement directly from my calipers into my data spreadsheet. I’m hoping it’s going to save time ultimately (though I’m still recording everything on paper for backup). Because of the way the input is set up, it’s easier … More Column QC
It was a breakneck two weeks of sampling, but we’ve caught, measured, and released all the lizards in the island experiment! The 2018 census is in the books. Or at least, on a huge stack of data sheets waiting to be typed into my computer. The lizards are doing great! All of the populations are … More The lizards are in the books!
Initially I thought getting to Redonda was going to be a challenge, but the helicopter made that aspect of the trip a delightful adventure. Living on Redonda for a week, though—that was tough. In retrospect, I’d say the challenge was simultaneously harder than anticipated but more comfortable than I’d feared. Here’s a panorama of our camp: There … More Living on Redonda
I’ve decided to break up the Redonda posts thematically. There’s a bit of a beginning, middle, and end to the trip, but the experience day-by-day makes less sense than talking about big things that we were working on in Redonda that often spanned several days. First up, getting to Redonda! As I’d mentioned previously, the best … More Helicoptering to Redonda
Alright, this is a little passé now that I’m back, but I think I’d be remiss talking about all of our adventures on Redonda, Antigua, and Great Bird Island without at least mentioning some of the preparations. Preparing for the Redonda expedition was some of the most challenging fieldwork prep I’ve ever done. Geoff, a science write … More Heading out!
As I said in the previous Redonda post, I’m headed to the island in search of the three endemic species of lizards living there. My goal is to gather as much baseline data as possible on the natural history of these lizards so we can come back in a year, or in 10 years and … More Working on Redonda
Yesterday’s post was a bit of teaser for the setup of the high-speed video. Now let’s see a couple of examples! (For full effect, I’d recommend playing this on full volume in the background. Rest assured, once we have a highlight reel of lizard runs we’ll definitely be creating a montage of our own) There’s all … More And some high-speed videos
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
Spotting these anoles in the field was one of the harder challenges of the field work in the Bahamas. They can be exceptionally well camouflaged against the right background and unlike Podarcis, they didn’t really do a lot of running until you were really close to them. Here are a few examples: The trick is to … More Masters of Camouflage
