The question I would pose (and we'll have to see if the 
paper addresses this): 

How much of that 4.4 kg/sq km is likely to actually be
available, given that every other carnivore nearby is going 
to have at it as well, some of whom will be much closer by 
chance (especially when the food is clumped, and not 
actually distributed as the average)?
