Adventures in Borneo

In August 2024, I had the good fortune to travel to Borneo to attend the 10th World Congress of Herpetology (10WCH). This conference (held only once every four years) was held in the city of Kuching in the Malaysian state of Sarawak. I presented three talks at 10WCH, one in a symposium on amphibian conservation (“Conservation status and natural history of a mountaintop endemic: Updates on the golden treefrog from Trinidad” co-authored with Dan Borowsky, ‘23) and two in a symposium I organized with my colleague Yeong-Choy Kam (Tunghai University, Taiwan) called “Ecology, Evolution and Behavior of Phytotelma-Breeding Anurans.” It was a wonderful symposium and conference in a wonderful and exotic city. The list of talks in our symposium can be found below:

Introduction to the Symposium (Rick Lehtinen, The College of Wooster, USA)

Ponds, pools, or puddles? Offspring rearing and site use in Bornean frogs breeding in small aquatic microhabitats (Johana Goyes Vallejos, University of Missouri, USA)

Males care early and more than late developing embryos supports the harm to offspring hypothesis in an arboreal breeding treefrog (Yuan-Cheng Cheng, Tunghai University, Taiwan)

Overcoming the lack of data for rare bromeliad-dwelling frogs from Brazil (Izabela M. Barata, Durrell Wildlife Conservation Trust, UK)

Is bromeliad breeding in poison frogs a commensalism? (Rick Lehtinen, The College of Wooster, USA, co-authors Mackenzie Goltz ‘20, McKenna Gassman ’21, and Vincent Dileo ‘24)

Cooperative breeding of Theloderma asperum (Yi Yang, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences)

Living with the enemy: communication, kin discrimination and cannibalism in poison frog larvae (Bibiana Rojas, University of Veterinary Medicine Vienna)

A Voice to the Voiceless: New Research on the Endangered Golden Tree Frog

In November 2022, I had an amazing experience on top of El Tucuche (the second highest mountain on the island of Trinidad). I was lucky to be the first person to hear the Golden Tree Frog vocalize. This endangered species is restricted to only four mountaintops in the world and was thought for many years to be voiceless. Turns out, it is not voiceless, you just have to be persistent and get a little lucky to hear it call! See our recent publication that describes these vocalizations for the first time. Thanks to Renoir Auguste (University of the West Indies) and Dan Borowsky (’23) for helping make this happen.
