Cocobolo Nature Reserve Monitoring

Cocobolo Nature Reserve Monitoring

I’m leaving Saturday for another round of research and monitoring on the endangered Limosa Harlequin Frog (Atelopus limosus) monitoring with Alex Shepack, Michael Roy, and Abel Batista in the wonderful Cocobolo Nature Reserve in Eastern Panama. We’re looking for more clues on the enigmatic behavior of the deadly amphibian chytrid fungus in the area and the mechanisms that allow some local frogs to survive. In addition we’ll be setting up opportunities for student research on the project through the Roger Tory Peterson Institute of Natural History and Yale...

Limosa Harlequin Toad (Atelopus limosus) & RTPI in New Scientist

Limosa Harlequin Toad (Atelopus limosus) & RTPI in New Scientist

In the 60 years that the illustrious journal New Scientist has been around they’ve never run a photo-led feature. I’m very proud and honored that they decided to break with that tradition with a story on our work with endangered frogs in Panama. Our research on a population of the exceedingly rare Limosa Harlequin Toad (Atelopus limosus) in Cocobolo Nature Reserve in Panama will hopefully give us more information on why these frogs are seemingly doing alright while its surrounding populations are going extinct. And with some luck, that information can help direct conservation...

Leaf-litter Toads (Rhinella alata)

These Leaf-litter Toads (Rhinella alata) were along a stream bank yesterday in Chagres National Park in Panama. It was great to see this species that can sometimes blend in well with the leaf litter. They also remind me of another toad Twan and I will be checking in on this week – the Atelopus limosus, as it will be the fourth year we will be doing work with a population deep in the Cocobolo Nature Reserve in Panama.

Checking on the Limosa Harlequin Frog

Checking on the Limosa Harlequin Frog

Twan and I are currently checking in on the Limosa Harlequin Frog (Atelopus limosus) population in Panama in our continued effort to survey their health and status. This past January I visited them and brought back the great news that their population was still holding steady. During the time I surveyed them I found four adults, six sub-adults, and 17 metamorphs. I even found adults higher up in the preserve than previously spotted leading to the suspicion that the population may be increasing. This theory is something we are exploring and will try to confirm during this trip. When we...
