Some prettier pictures from Redonda

Alright, yesterday’s pictures were a bit gross, I apologize. Today’s will be a little nicer. Here’s just a quick photo dump and some captions of a few more scenes around the island, plus lizards!

RedondaHelicopterLanding.jpgHere’s the helicopter coming in for a landing. Notice all the beautiful grass!

A.Nubilus.M.TreePerch.jpgHere’s a male on a perch checking out this fellow (below) who was on the next branch over and sending some pretty strong “get outta here” signals.

A.Nubilus.M.DewlapSide.jpgAnd here’s a female. Not the one the two guys above were fighting over but another, that I spotted not too far away.

Here’s a shot from up on Redonda of Geoff taking a picture in the evening sun.

And here’s one showing the rocks up top and the path along the spine of the island.

And, finally, here’s another pretty picture from the Helicopter because I just can’t get over how fun and pretty it is riding up front!

Revisiting Redonda

Revisiting Redonda one year after the goats were helicoptered off and the vermin e-rat-icated was every bit as exciting and gratifying as I could have hoped last year. I’d guessed we might see some grasses fighting their way up through the dust and rocks, maybe a few extra lizards happy to not have to watch out for day-hunting monster rats. What we actually saw exceeded my most optimistic expectations though.

Here’s a panorama I captured in 2017:

2017And another, from exactly the same spot, in 2018: 2018

With the astounding regrowth of grasses and sapling trees all over the island has come a complete transformation. The roots are locking in all of that dust and so instead of a fine powder of aerosolized guano, walking through Redonda is mostly dust-free and soil is starting to be stabilized and created. I can only imagine what this is doing for water quality in the immediate vicinity.

In addition, we saw insects everywhere and a much larger diversity than last year. Our helicopter was greeted by butterflies and on the first night we discovered several terrifying amblypygids had made our workspace their home; scuttling around every night on the prowl.

Some things remained the same; we still worked in the concrete manager’s house which is still the best source of shade and shelter on the island. Our work was overseen this year by more than a dozen anoles who agreed it was a terrific spot to escape the heat of the day.

The lizards of Redonda have made a pretty staggering recovery from last year. We calculated density in two ways: with a long transect around the whole island where we counted each lizard we saw, and a mark recapture plot where we catch each lizard, give them a unique number, and then resurvey two days later to see how many of them we find and how many unmarked ones we’d missed. By both estimates we think the anole population and the ground lizard (Pholidoscelis) have doubled.

IMG_8868.jpgHere was lizard number 50 at one of the plots and we weren’t even done catching that morning!

Redonda is doing great and I am so pleased to get to see the first year of its transformation. I can only imagine how much it’s going to continue to change into the future. I can’t wait to go back and find out!

Next Stop, Redonda

It’s been a hurried couple of weeks in Paris with lots of work on writing and slowly getting acquainted with working and living in a new country. Just as I was starting to find my way around the neighborhood though it’s time to head back into the field.

redondaThis time last year I was on the island of Redonda to survey the endemic lizards in tandem with a group working to eradicate the invasive rats menacing the islands’ fauna and flora. The eradication was a success, and now I’m heading back out to the island to see how things have changed. I’ll be catching and measuring lizards again, taking pictures of the vegetation, and looking to see what immediate differences removing these pests can have. I’m excited to see the changes and I’ll be posting updates as soon as I get off the island. For now though I’m at a run trying to get final supplies because we won’t have access to anything we haven’t brought with us for the next week!

Until I get back though, here’s a recent story in the Boston Globe about the lizards I’m working on at Harvard.

 

My lizards are on Atlas Obscura!

Geoffrey Giller is a recurring character on the blog and while people are usually most impressed by his terrific science journalism, or maybe his stunning nature photography, I’m very proud to share that he’s on his way to becoming a champion lizard catcher!

Geoffrey has helped out on trips to Redonda and to the Bahamas and will be returning with me to Redonda next month (more on that soon). He recently wrote a piece on Atlas Obscura about the Bahamas work and the lizard colony at Harvard that I wanted to highlight. You can see it here. Enjoy!

A video from Pine Cay, Turks and Caicos

I haven’t posted all that many photos from our time in Turks and Caicos, in part because I was worried about my friends on the islands as Hurricanes Irma and then Maria rolled through. Luckily the team stayed safe through both storms. Unfortunately, the damage and time delay from the storms means that the eradication efforts are going to have to be put on hold for a year.

Before the eradication was postponed I put together this little video. I held off posting it when the project future was in limbo but it seems a waste not to share it. We will be continuing this work and returning as soon as we can to look at the Anoles of Pine Cay following removal of the rats. It’s just going to be a slightly longer timeline than originally planned.

Hope you enjoy the footage. Remember to watch on “HD.”

I’m back from Turks and Caicos

I’m back from Turks and Caicos, and not a moment too soon. For those of you watching the weather they’re buckling down for a pretty hard hit from Hurricane Irma. I’ll update you all with more information about the trip – it was fantastic – but for now just wanted to post a few pictures and say I’m safe and sound back in Cambridge!

Next stop, Turks and Caicos!

Frequent visitors to the blog will remember my Redonda adventure earlier this year. If you want to catch up, here are a few posts about my trip to Antigua and Barbuda, and from there to the remote island of Redonda. My goal was to collect baseline data so I could figure out how three endemic lizards adapt following a rat extermination effort.

The group responsible for the rat eradication is at it again, this time in Turks and Caicos.  Next week, I’m headed to Pine Cay to see how lizards, specifically Anolis scriptus, will change following the eradication.

I don’t have pictures to share just yet, but here’s a map of the destination:

(by the way, who could possibly give this place a one-star review?!)
