Hawksbill Nesting Project

New NCSU graduate student Andy Maurer sent in an update on his research on Antigua.  Cool stuff…..

Hawksbill nesting season with the Jumby Bay Hawksbill Project in Antigua is well under way. After 3 weeks of monitoring, we have had 25 nests laid by 21 females. Many more to come. There have been 8 first time nesters, or neophytes, already this […]

Island Hopping

A Cuban tree frog, Osteopilus septentrionalis, found his way inside the airplane cabin and flew to San Salvador. It departed at San Salvador. I think the flight left from Nassau, but maybe Abaco.

Olivia Patterson was kind enough to share these photos, but the title is my fault.

Lizards have it tough!

Last week Craig sent me a few photos of a Curly-tailed lizard in the jaws of a Bahamian racer (Cubophis vudii).  While we often imagine Curly-tails as predators, they are certainly not at the top of the food chain here. Bahamian racers, boas, and red-tailed hawks (see previous post) undoubtedly consume many Curly-tailed lizards.

I don’t really know too much […]

A new non-native species on Abaco: the Eastern narrow-mouthed toad.

While grabbing a late-night dinner in Dundas town last night, I heard a chorus of shrill, nasal bleats emanating from behind the building. I recognized the call right away as the mating call of the Eastern narrow-mouthed toad (Gastrophryne carolinensis). The Eastern narrow-mouth toad is native to the Southeastern United States and while it has been recorded from New Providence, and Grand Bahama, […]

New Hawksbill Project

A BBC story on an important hawksbill nesting location in Antigua.  Timely, as we have just accepted a new student, Andrew Maurer, into the NCSU graduate program.  Andrew will conduct his field work at this site, looking at factors that affect nesting success in hawksbills.  Some of the hawksbills that take up residence in The Bahamas, may well have […]

Loggerhead Connection

A new paper on the repeated migrations of loggerheads from their residence areas in The Bahamas to nesting beaches in the Dry Tortugas.  Remarkable they track back to the same areas after each trip.  Here is the paper summary:

Background: Delineation of home ranges, residence and foraging areas, and migration corridors is important for understanding the habitat needs for a […]

Sometimes Protecting One Species Harms Another

An article about how increasing parrotfish populations in parts of the Pacific may be harming coral reefs.  This parallels the potential scenario in The Bahamas, where increasing turtle populations may graze down seagrass beds, as has been seen in Bermuda.  Photo from Jenny Huang via Flickr.

Ever-adaptable anoles might cope with a hotter world

The Washington Post covers a recent article on how Anolis lizards may be able to adapt to climate change (LINK).

Male brown anoles move further from their place of birth

Brown-Anole.jpg

Jonathan Losos over at Anole Annals breaks down a new paper by the Calsbeek lab at Dartmouth. The topic of the paper is the dispersal of young away from their place of birth and the fitness consequence of that movement in brown anoles (LINK to pdf).
