Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves.. Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
The Lotka–Volterra predator-prey model makes a number of assumptions about the environment and biology of the predator and prey populations: [5] The prey population finds ample food at all times. The food supply of the predator population depends entirely on the size of the prey population.
A cheetah exhibiting pursuit predation. Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group.It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use concealment, luring, exploiting of surroundings and ...
Pursuit predation becomes a better strategy than ambush predation when the predator is faster than the prey. [2] Ambush predators use many intermediate strategies. For example, when a pursuit predator is faster than its prey over a short distance, but not in a long chase, then either stalking or ambush becomes necessary as part of the strategy. [2]
Persistence predators can hunt prey many times their size. No extant members of Archelosauria are known to be long-distance hunters, though various bird species may employ speedy pursuit predation. Living crocodilians and carnivorous turtles are specialized ambush predators and rarely if ever chase prey over great distances.
Predator–prey reversal is a biological interaction where an organism that is typically prey in the predation interaction instead acts as the predator. A variety of interactions are considered a role reversal. One type is where the prey confronts its predator and the interaction ends with no feeding.
Aggressive mimicry often involves the predator employing signals which draw its potential prey towards it, a strategy which allows predators to simply sit and wait for prey to come to them. The promise of food or sex are most commonly used as lures. However, this need not be the case; as long as the predator's true identity is concealed, it may ...
Hamilton also went on to model predation in two-dimensions, using a lion as an example. Movements that Hamilton proposed would lower an individual's domain of danger were largely based on the theory of marginal predation. This theory states that predators attack the closest prey, who are typically on the outside of an aggregation. [1]
