Fruit abundance and moonlight shape sex-specific nocturnal activity and movement in kinkajous (Potos flavus)

This study examines how fruit abundance and moonlight influence sex-specific nocturnal activity and movement in kinkajous, finding that fruit abundance increases travel and decreases feeding, while moonlight affects males and females differently.

iNaturalist mammal observations classified by evidence type

The paper classifies evidence types of iNaturalist mammal observations using machine learning, creating a dataset with 1.33 million annotated observations.

Automated Parameter Estimation for Camera Trap Density Models Using Computer Vision-Enhanced Distance Sampling

This paper develops an AI-driven pipeline to estimate animal density from camera traps by automatically extracting key parameters using computer vision and a hierarchical distance function.

MoveTraits - A database for integrating animal behaviour into trait-based ecology

The paper introduces MoveTraits, a database integrating animal behavior into trait-based ecology by standardizing movement traits from biologging data to improve global change predictions and biodiversity assessments.

Mammal niches are not conserved over continental scales

The paper shows that environmental niches of North American mammals vary spatially and are not conserved, challenging the niche conservatism hypothesis and suggesting local adaptations or unmodeled interactions.
