PriMAT: A robust multi-animal tracking model for primates in the wild

PriMAT tracks and identifies primates in the wild using bounding boxes, achieving 84% accuracy in lemur identification with minimal labeled data.

Social Tolerance and Innovation in Capuchins: socially more tolerant brown capuchins are better problem-solvers than less tolerant white-faced capuchins

This study compares social tolerance and problem-solving abilities between brown and white-faced capuchin monkeys, finding that brown capuchins are more socially tolerant and better at solving novel food puzzles.

Same data, different results? Machine learning approaches in bioacoustics

The paper evaluates machine learning methods for caller identity classification in mammalian vocalizations, finding Mel-frequency cepstral coefficients and random forests provide consistent results across datasets.

Foraging competence and scrounging tolerance enhance social relationships in a socially tolerant wild primate

The study examines how foraging success and scrounging tolerance affect social relationships in redfronted lemurs, finding that more successful individuals and those scrounged more often receive more affiliative behavior.
