Intraguild predation is common in nature and widespread across communities and ecosystems. [2] Intraguild predators must share at least one prey species and usually occupy the same trophic guild, and the degree of IGP depends on factors such as the size, growth, and population density of the predators, as well as the population density and behavior of their shared prey.

Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre
Defensive Batesian mimics, like this bumblebee-mimicking hoverfly, are the antithesis of aggressive mimics.. Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped.
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
The predatory species mediating indirect interactions between the mimic and the model is variously known as the [signal] receiver, dupe or operator. By parasitising the honest warning signal of the model, the Batesian mimic gains an advantage, without having to go to the expense of arming itself. The model, on the other hand, is disadvantaged ...
What’s more, no one under the age of 18 is allowed a license to marry anyone over the age of 21 — a necessary hedge against predatory relationships between teen girls and much older men. That ...
Salacious headlines involving teachers who prey on students have segued into the storylines of plenty of movies and television series over the years. But with FX’s “A Teacher,” creator ...
About 10% of predator–prey relationships have smaller organisms preying on larger ones. These are all active attacks though, unlike the Epomis larvae's strategy to lure the larger amphibian to them. Wizen and Gasith suggest that the strategy could have begun through evolution as an anti-predator defense, and later became the means of living ...
