In the study: ‘Environmental drivers of global variation in home range size of terrestrial and marine mammals’, the relationship between home range size (HRS) and environmental variables was quantified, accounting for species traits and their interactions with environmental variables for terrestrial and marine mammals. A novel, comprehensive dataset of 2,800 HRS estimates from 586 terrestrial and 27 marine mammal was used. The results indicated that terrestrial mammal HRS was on average 5.3 times larger in areas with low human disturbance (human footprint index [HFI] = 0), compared to areas with maximum human disturbance (HFI = 50). Similarly, HRS was on average 5.4 times larger in areas with low annual mean productivity (NDVI = 0), compared to areas with high productivity (NDVI = 1). In addition, HRS increased by a factor of 1.9 on average from low to high seasonality in productivity (standard deviation (SD) of monthly NDVI from 0 to 0.36). Of these environmental variables, human disturbance and annual mean productivity explained a larger proportion of HRS variance than seasonality in productivity. Marine mammal HRS decreased, on average, by a factor of 3.7 per 10 °C decline in annual mean sea surface temperature (SST), and increased by a factor of 1.5 per 1 °C increase in SST seasonality (SD of monthly values). Annual mean SST explained more variance in HRS than SST seasonality.
