Intraguild predation reduces redundancy of predator species in multiple predator assemblage
Journal of Animal Ecology, 2006Summary Interference between predator species frequently decreases predation rates, lowering the risk of predation for shared prey. However, such interference can also occur between conspecific predators. Therefore, to understand the importance of predator biodiversity and the degree that predator species can be considered functionally interchangeable,

The first task faced by the writer of any book is the setting of limits around the material to be covered. This is primarily an exercise in definition and, as with any such exercise, is an invitation to dispute. Nearly every textbook dealing with ecology offers a unique definition of predation.

Predating predators: An experimental study [PDF]
, 2001 Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3.

The interaction between predator and prey is an evolutionary arms race, for which early detection by either party is often the key to success. In aquatic ecosystems, olfaction is an essential source of information for many prey and predators and a number

Vervet monkeys give different alarm calls to different predators. Recordings of the alarms played back when predators were absent caused the monkeys to run into trees for leopard alarms, look up for eagle alarms, and look down for snake alarms.

The Journal of Industrial Economics, 1988
ONE common assumption in the post-McGee [1958] predatory pricing literature has been that the predatory firm must be larger (have 'deeper pockets'), than the victim of the predation, usually an entrant. This assumption stems from a model of predation in which the contesting firms sell at levels below cost until one of the firms exits after exhausting ...

A predator's perspective of nest predation: predation by red squirrels is learned, not incidental
Oikos, 2009Nest predation has been used to explain aspects of avian ecology ranging from nest site selection to population declines. Many arguments rely on specific assumptions regarding how predators find nests, yet these predatory mechanisms remain largely untested.

Chemical alarm signalling in aquatic predator-prey systems: A review and prospectus
, 1998The importance of chemical cues in predator-prey interactions has recently received increasing attention from ecologists. The sources of chemicals to which prey species respond often originate as cues released by the predator (reviewed by Kats and Dill ...

Spatial Economic Analysis, 2012
Abstract In a spatial economic context, we analyse the incentive to prey of an incumbent facing the potential entrance by a rival. We show that the existence of space modifies the incentive to prey of the incumbent and the resulting equilibrium.
