The Dominican nuns at the Monastery of Our Lady of Health in Mexico have taken on a crucial role in the conservation of the critically endangered achoque salamander, with fewer than 150 individuals remaining in the wild. Their efforts have transformed a 150-year tradition of breeding these salamanders for cough syrup into a vital conservation program. Scientists from Chester Zoo have partnered with the nuns to develop a microchipping technique that allows for the identification of individual salamanders without harming them. This collaboration aims to monitor the health and population of the species, which is threatened by pollution, overfishing, and climate change affecting their natural habitat, Lake Pátzcuaro. The nuns' dedication and the innovative research efforts are essential for the future of the achoque salamander.
