Two gerbils of the Negev: A long-term investigation of optimal habitat selection and its consequences

  title={Two gerbils of the Negev: A long-term investigation of optimal habitat selection and its consequences},
  author={Michael L. Rosenzweig and Zvika Abramsky},
  journal={Evolutionary Ecology},
Optimal foraging theory has entered a new phase. It is not so much tested as used. It helps behavioural ecologists discover the nature of the information in an animal's brain. It helps population ecologists reveal coefficients of interaction and their patterns of density-dependent variation. And it helps community ecologists examine niche relationships. In our studies on two species of Negev desert gerbil, we have taken advantage of the second and third of these functions. Both these gerbils… CONTINUE READING
