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.

Environmental Uncertainty Affects Movement and Space-use in Sheep

This study shows that Merino sheep adjust their movement and space-use behavior in response to environmental uncertainty, moving more directionally and covering greater distances as they gain more foraging knowledge.

Using social information improves individual foraging efficiency in sheep

This study shows that naive sheep forage more efficiently when paired with informed individuals, using social information to locate food faster and spend less time exploring.

Heat stress conditions affect the social network structure of free-ranging sheep

This study shows that heat stress conditions in free-ranging sheep increase social network connectivity and alter social positioning based on shade use behavior.
