Assessment And Decision Making In Animals: A Mechanistic Model Underlying Behavioral Flexibility Can Prevent Ambiguity, Amos Bouskila, Daniel T. Blumstein
Amos Bouskila
Understanding how animals make decisions is a fundamental question in behavioral ecology which has cascading effects on how animals respond to environmental variation. An explicit model of the mechanisms of information processing and decision making can help prevent conflated definitions and ambiguous interpretations. Unambiguous definitions are crucial for clear communication between theoreticians and empiricists and for the rapid advancement of studies of decision making, Moreover, employing a clear model of underlying proximal processes will help bridge the gap between cognitive psychology and behavioral ecology and should aid scientific advancement. We present a simple model to guide studies of assessment and …
Interactions Between Predation Risk And Competition - A Field-Study Of Kangaroo Rats And Snakes, Amos Bouskila
Interactions Between Predation Risk And Competition - A Field-Study Of Kangaroo Rats And Snakes, Amos Bouskila
Amos Bouskila
The effects of predation risk from snakes on microhabitat use of kangaroo rats (Dipodomys deserti and D. merriami) was studied in the Mojave Desert. I concentrated on the effects of the predator on the foraging behavior of the rodents and eliminated effects of prey capture on prey population size. Foraging stations contained three seed trays, one in each of three microhabitats (Open, Bush, Grass). The amount of seed left in each tray after one night of foraging was used to assess the responses to predation risk and other foraging costs; additional data were collected during direct observations and by trapping. …
