Homogenization of terrestrial mammal assemblages in human-modified rainforests

Data on medium and large terrestrial mammal species was obtained in 22 forest patches and 4 continuous forest sites in the fragmented Lacandona rainforest, Chiapas, Mexico. We sampled mammals using camera-traps, ground tracks and direct sightings in 2011 and 2017. For each site, we measured metrics of landscape composition (i.e. percentage of forest cover and matrix openness) and landscape configuration (i.e. number of patches, edge density and mean inter-patch distance). We analyzed sample completeness in each site and removed sites with low sample coverage (Cn
