Human pressures drive compositional homogenization and functional shifts in Southeast Asian mammal communities

Here, we compiled an extensive camera-trapping dataset of medium and large-sized mammals from 3,509 sites across tropical and temperate forests in Southeast Asia. We quantified compositional homogenization and functional diversity trait patterns in relation to human pressures within and across forests. Env.csv: Basic information and standardized environmental covariates of each study area. "Area": ID of study areas; "Lon": Lontitude; "Lat": Latitude; "n_Cameras:" the number of camera sites; "Effort": trapping effort; "PD": patch density; "HM": human modification index; "BC": building density change; "RAIH": relative abundance index of human; "RAIL": relative abundance index of livestock; "Alt": altitude; "Rough": terrain roughness; "Bio14": precipitation of driest month; "NPP": net primary productivity; "TC": tree-cover change; "Biome": biome of the study area; "Reference": data source.Comm.csv: Number of independent observation events of each species within each study area.Traits.csv: Functional traits of each species. "Scientific": Latin names of species; "BodyMass.Value": body mass; "Diet": consumption proportion of food resources; "ForStrat.Value": foraging stratum; "Activity": circadian rhythms; "litter_size": litter size; "habitat_breadth_n": number of habitat types.R version 4.4.2 were used to calculate the log-response ratio of homogeneity (LRR homogeneity), log-response ratio of shift (LRR shift), as well as functional diversity metrics and to produce Figure 2-5 in the manuscript.
