Amphibian biodiversity is declining worldwide and collecting information about their habitats and populations via monitoring is vital for conservation efforts. However, it is difficult to accurately monitor amphibians using conventional methods. To address these issues, scientists have developed a novel technique to identify the amphibious species that live in an area through environmental DNA analysis. It is hoped that the new method will revolutionize species monitoring, as it will enable anyone to easily survey a habitat by collecting water samples. Leer más.

In this work, I tested these hypotheses on natterjack toads (Epidalea calamita). Specifically, I gauged activity time, exploratory behaviour and boldness in standard laboratory conditions, and assessed whether they correlated with body size and antipredator strategies, namely sprint speed, parotoid gland area and parotoid gland colour contrast.  Leer más.
