Nocturnal basking in a freshwater turtle from Trinidad

An incidental observation of nocturnal basking was recorded with the scorpion mud turtle in an urban area in southern Trinidad which was included in the global assessment. Further, surveys using wildlife cameras took place at Point-a-Pierre Wildfowl Trust to further evaluate whether turtles were basking at night, or only during the day. The only species caught on cameras were the non-native red-eared sliders (Trachemys scripta elegans; native to the United States), and they were only recorded basking during the day. Interestingly, globally, only tropical (but not temperate) species were observed basking at night, suggesting that environmental temperature plays a key role in this behaviour. It would be noteworthy if more observations of basking behaviour are recorded for the other freshwater turtle species in Trinidad. I encourage local herpers and herpetologists to keep an eye on the freshwater turtles near them, so we can use the information to better protect them! ||| Link to early view of study here.

Amphibians and their Conservation in Trinidad and Tobago

A new book has been published "The Conservation and Biogeography of Amphibians in the Caribbean". In it, Chapter 12 features an updated review of the "Amphibians and their conservation in Trinidad and Tobago". The book is edited by Neftali Rios-Lopez and Harold Heatwole, published by Pelagic Publishing. Summary of the book's description: An expansive and detailed review of the biology of Caribbean amphibians, considering their threats, conservation and outlook in a changing world. Amphibians are the group of vertebrates undergoing the fastest rate of extinction; it is urgent that we understand the causes of this and find means of protecting them. This landmark illustrated volume brings together the leading experts in the field. As well as offering an overview of the region as a whole, individual chapters are devoted to each island or island-group and the measures used to protect their amphibians through legislation or nature reserves. The biological background of insular biogeography, including its methods, analysis and results, is reviewed and applied specifically to the problems of Caribbean amphibians – this includes a re-examination of patterns and general ideas about the status of amphibians in the Anthropocene. The Conservation and Biogeography of Amphibians in the Caribbean offers an important baseline against which future amphibian conservation can be measured in the face of climate change, rising sea level and a burgeoning human population. The book can be bought on NHBS or Amazon. DOI: 10.53061/RCJP8789
