Description of the variables used to predict extinction risk transitions in the random forest model

Class	Variable	Description and source	Source
Pressure	High HFP extent	Proportion of species range overlapping with high human footprint values in 2009.	14
Pressure	High HFP change	Difference in the proportional overlap between species range and high HFP during 1993–2009.	14
Pressure	Human population density	Density of human population in year 2000.	46
Pressure	Human population growth	Human population growth, proportional increase in human population between 1990 and 2000.	47
Pressure	Travel time to cities	Accessibility from major cities, measured as travel time.	48
Life history	Taxonomic order	Species taxonomic orders.	35
Life history	Gestation length	Gestation length, a proxy of species reproductive output.	49, 50
Life history	Weaning age	Weaning age, a proxy of species reproductive timing.	as above
Life history	Body mass	A generic proxy of species life history and energetic requirements	49– 51
Life history	Diet	Dietary category: carnivore ( > 90% animal matter ingested), omnivore (10–90%), herbivore ( < 10%).	52
Life history	Habitat class	Species preferences of macro-habitat categories: aquatic, artificial, caves, desert, forest, grassland, rocky areas, savanna, shrubland, generalists (two or more of the previous categories).	35, 53
Environment	NDVI	Normalized difference vegetation index, proxy of primary productivity, registered from year 2013.	54
Environment	Tree cover	Percentage tree cover values registered in year 2000.	55
Environment	Habitat prevalence	Proportion of suitable habitat within species range.	53

Variables are aggregated into three main classes (human pressure, life-history, environmental characteristics)
