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 definition of preference will therefore impact on understanding switching. The most common definition of preference is the relationship between the ratio of prey in the environment and the ratio of prey in a predator's diet. It has been independently proposed a number of times and is described by the equation:
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 ...
Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
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.
For example, exploitative interactions between a predator and prey can result in the extinction of the victim (the prey, in this case), as the predator, by definition, kills the prey, and thus reduces its population. [2] Another effect of these interactions is in the coevolutionary "hot" and "cold spots" put forth by geographic mosaic theory ...
The sonic blast stuns the prey, allowing the tiny shrimp to feast without having to engage in a fight. It’s a good reminder that small can be mighty. Image credits: Wendy Graham
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.
