Herpetological Survey 2014 led by Norman Greenhawk

HERPETOLOGICAL EXPEDITION JULY-AUGUST 2014

The steep and remote areas of Icaco and Hormiga Valleys of Las Casas de la Selva have never been surveyed for amphibians. Herpetologist Norman Greenhawk led a team of volunteers into the forest to search for target species of frogs in this vast area, to identify and gather information about amphibians to better assist with the future management of this area. The expedition started on 16th July, and continued to 8th August 2014. The team set up camp in the forest, prepared their own food, and faced some days of extremely challenging windy and rainy weather, including an interruption of the study by Tropical Storm Bertha! The team included college students from the continental US, Puerto Rico, an Earthwatch Teen Team, and Dr. Gabriela Agostini from Argentina. They and came back with a lot of data.

The target species that were confirmed to exist in the valleys were: IUCN Endangered Eleutherodactylus wightmanae (the Coqui Melodioso), IUCN Vulnerable Eleutherodactylus cooki (Coqui Guajon), and IUCN Critically endangered Eleutherodactylus richmondi (Coqui Caoba).

During the surveys, the team sampled for Chytridiomycosis, an infectious disease of amphibians, caused by the chytrid Batrachochytrium dendrobatidis, a non-hyphal zoosporic fungus, that is currently killing off amphibians around the world. GPS co-ordinates of appropriate information were taken to allow for mapping of the range of target species within the valley, and high quality photos of the frogs were taken to help show the myriad variation of colors and patterns within a single species.

The initial survey is over and the data is being compiled. Norman has met with personnel of the US Fish and Wildlife Service to help determine future monitoring and research. Once the results of the Chytrid sampling are delivered from the San Diego Zoo, a report will be written up and submitted to a peer-reviewed journal for publication. This survey will continue with a smaller team, as the mountain ridge that separates the two valleys needs to be accessed and sampled.

Norman expresses deep gratitude to team members Sarah Bryan, Jessica Rosado, Marla Gonzalez, Sara Gabel, Sara Zlotnik, Alessandra Belmonte, Sam Boas, Kaitlin Panzer, Lauren Billy, and co-team leader Gabi Agostini. Huge thanks also to Earthwatch Team members: Alana Salas-Yoshii, Josie Icaza, Samantha Riesberg, and their facilitator, Sushmita Sridhar.

Big, big thanks to the Mohammad bin Zayed Species Conservation Fund, CREOi, Roland Pesch and Kathy Rosskoph, without whom this survey would not have been able to be carried through.

Lastly, a special thanks to Thrity Vakil & Andrés Rúa for help with logistics, Leah Chevrier-Rappaport for extra volunteer help, and to Jan Zegarra of the US Fish & Wildlife Service for his encouragement, help with analyzing the results, and for consultation concerning future research possibilities.

Vanderbilt University March 1-8, 2014

Vanderbilt University students have just spent several days with us at Las Casas de la Selva, and we have had a super time, working hard! Students learnt the art of plastering on the bunkhouse, led by Andres, and also helped with heavy labor and soil renewal on the Papaya Terraces with 3t. In their time here, they also got to do a leaf litter study with Norman and hiked into the forest. Thank you for your remarkable teamwork, and thanks Zach and Julia, team leaders who did a great job. We salute you all! Come back and see us again soon.

Pepperdine University Feb 22-28, 2014

This was our third year hosting a team from Pepperdine University at Las Casas de la Selva. Norman Greenhawk, as crew leader worked with the students on the main hill-trail and everyone worked super hard to build steps, and to make the walk up and down the hill much safer and more comfortable. Hauling rocks and gravel from the river and carrying then up hill was hard work, and it was extremely satisfying to us to see a group getting on so well with the task at hand. The materials used were recycled from all over the homestead and the wood was from the old drying shed that Pepperdine students helped us to deconstruct in 2013. The work was muddy, and in rainy conditions for a few days, but sunshine prevailed and we all had a superb time with this great bunch! Pepperdiners, we salute you all. Please stay in touch.

Frogging

Frogging at Las Casas de la Selva! Patricia Caligari (center) is pursuing a Masters Degree at University of Puerto Rico. L-R: Rosangela, Michel, Naomi and Monica are her assistants in the field and they are taking credits as part of their bachelor degrees.

Geographic assessment of the response of three different endemic Puerto Rican anurans to the pathogenic fungus Batrachochytrium dendrobatidis (Bd)

ABSTRACT

Chytridiomycosis is a lethal infectious disease caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd), which is responsible for the extinction of many amphibians worldwide. In Puerto Rico three species of Eleutherodactylus disappeared potentially due to this pathogen, and many others are at risk. A synergistic effect between Bd and climate was shown for two species at El Yunque, but this relationship has not been tested in other species or forests. The purpose of this study is to evaluate the status of Bd in three endemic species, Eleutherodactylus wightmanae, Eleutherodactylus coqui, and Leptodactylus albilabris, which differ in conservation status, ecology and life history, in three highland forests across the island. Results from this study will enhance our understanding of the mechanisms of Bd under enzootic conditions.

Her advisor is Dr. Patricia Burrowes, who also co-authored our biodiversity and frog study paper.

Norman on sabbatical

In 2012 Norman Greenhawk was honored by Earthwatch with a Neville Schulman Award. The award is given for the training of emerging environmental leaders. For the award, Norman submitted a proposal: “Herpetological Conservation in the Neo-Tropics: An Interdisciplinary Approach”, and he is currently two and a half months into his seven month sabbatical.

June 2013: Above: Norman Greenhawk with Nahir Tejada in the PARC (Panama Amphibian Rescue and Conservation Project) quarantine room, located at Summit Zoological and Botanical Park in Panama. The frogs are being stored here in temporary housing as the project finalizes it’s relocation to the new facility in the nearby community of Gamboa. Every day, over 150 plastic tanks of frogs have to be cleaned and the frogs have to be provided with fresh water and food. Norman is holding an Atelopus limosus and Nahir holds an Atelopus glyphus. Collectively, members of the genus Atelopus are known as “Harlequin frogs”, and are highly susceptible to the Chytrid fungus that is decimating frog populations worldwide. The goal of PARC is to preserve a genetically diverse breeding population in captivity in the event that these species go extinct in the wild, as the Panamanian Golden Frog (Atelopus zeteki) is currently.

He has spent a month at La MICA Biological Field Station in El Cope, Panama. He has worked with Dr. Julie Ray, a specialist of Panamanian snakes and has also interviewed citizens of the rural barrio of Barrigon about their attitudes and beliefs about snakes. His time in Panama will end with a stint at the Panamanian Amphibian Rescue and Conservation Project (PARC), which partners with the Smithsonian Tropical Research Institute. PARC is a captive breeding program dedicated to preserving genetically diverse populations of Atelopus frogs, a genus of frogs that are highly susceptible to the Chytrid fungus, a disease currently wiping out populations of amphibians all over the world. While working at PARC, he is continuing his interviews of local and indigenous peoples, focusing on beliefs about reptiles and amphibians in general, as well as perceptions about conservation organizations.

Norman also has had an opportunity to conduct a very sobering interview that helps showcase why he is so focused on community outreach and partnership. On May 30th, Jairo Mora Sandoval, a Costa Rican sea turtle conservationist, was murdered by poachers who were angered at his efforts to attract the attention of police to a huge illegal turtle harvest. By chance, a former Las Casas volunteer was working with Jairo’s group when the murder occurred. He met with Norman and shared his story of what happened; Jairo was a young man, 26 years old. The night before his murder, he spoke of wanting to propose to his girlfriend. He was well liked by the community, and even by many of the local poachers. Such examples of violence are extreme, but not unheard of. Norman hopes that his continued outreach to communities around each of the conservation projects he is working at will help in some small way to prevent future tragedies such as this- on July 3rd, Norman flies to Belize to work with a crocodile sanctuary that was burned to the ground two years ago by Maya Indians who erroneously thought that two village children had been eaten by the crocodiles. We wish the best for Norman on his intrepid explorations!
