Evaluating the efficacy of visual encounter and automated acoustic survey methods in anuran assemblages of the Yungas Andean forests of Argentina

Identifying adequate methods and tools for biodiversity monitoring is fundamental in ecology and conservation biology. Most of the standardised monitoring techniques involve the presence of the researchers at the survey sites meanwhile, passive acoustic monitoring (PAM) of the diversity of anuran sp...
