Population Estimation - Using Home Range Estimates

Where H =home range in hectares and W is weight in grams:

H = 0.002 W^1.02 herbivores

H = 0.059W^0.92omnivores

H = 0.11W^1.36 carnivores

H = 0.008W^1.08
all groups together r² = 0.6

H = f (1/precipitation, latitude)

H = f(sex, age) related to

H = f(weight)

Food consumption (FC)/day in grams

carnivores (C) FCC = 1.7W^{0.68 ± 0.02} FCC = 1.7 W^0.66 grams

Birds (B) FCB = 0.51W0^{0.63 ± 11} FCB = 0.5 W^0.66
