1. Using standardized camera trapping data and a new analytical method, scientists found that trophic guilds (a group of species that exploit the same resources) and body mass varies across 16 protected areas in tropical forests and three continents in relation to the extent of protected habitat and human pressures.

2. Insectivores were found to be sensitive to the size of protected habitat and surrounding human population density, while body mass distribution varied little among communities both in terms of central tendency and spread, yet community average body mass declined with proximity to human settlements.

3. Results suggest that broadly similar habitats and selective pressures shaped communities with similar trophic strategies and responses to drivers of change – similarities that provide a foundation for assessing assemblages under human-caused threats and sharing conservation measures.
