Abstract
The essay is a review of three models that are relevant to human–biodiversity relationships, and could be modified by researchers to further conceptualize, hypothesize, and in some cases, predict system dynamics. The first model, which applies the average adult body weight of Homo sapiens to statistical models predicting mammalian herbivore and predator density, suggests the degree to which our species has modified the landscape and channeled energy and nutrient flux in order to achieve densities that are today nearly three orders of magnitude greater than predicted for preagricultural humans. The second model makes explicit three types of risks to the viability of populations of native species: risks within the protected area, risks from between-area hazards, and risks at the reserve perimeter. The third model appears as a graphic representation of the theory of human density-driven agricultural change that endeavors to make Boserup’s powerful thesis more useful to ecologists.
