Coevolution and Mutualistic Relationships

A collection of flashcards covering key vocabulary related to coevolution and mutualistic relationships.

Coevolution

The evolution of interacting species in response to each other, where each species exerts selection pressure on the others.

Mutualism

A type of symbiosis where both species benefit from their interaction (+/+ interaction).

Symbiosis

A close physical relationship between two different species. Including mutualism, parisitism, commensalism

Parasitism

A type of symbiotic relationship in which one species benefits at the expense of the other.

Commensalism

A type of symbiotic relationship where one species benefits while the other is neither helped nor harmed.

Dispersive mutualism

A mutualism that involves the movement of one species exchanging its services for resources, such as pollination.

Defensive mutualism

A mutualism where one species gains protection against predators or parasites in exchange for providing food or shelter.

Resource acquisition

A mutualism that involves the exchange of resources between species, such as nutrients and carbohydrates.

Obligate mutualism

A mutualism that is essential for the survival or reproduction of one or both species involved.

Facultative mutualism

A mutualism that is not essential for the survival or reproduction of one or either species.

Character displacement

A mechanism that occurs when two species evolve different traits to minimize competition for resources.

Cheating prevention in mutualism

Mechanisms developed by one species to prevent another from gaining benefits without reciprocating.

Coevolution

Joint evolution of species in close ecological interaction over time

Tight coevolution

Reciprocal evolution of two closely interacting populations

Diffuse coevolution

adaptations in one population promote adaptations in one or more co occuring populations

Coevolution outcomes

Mutualism, competition_{, Consumer recourse}

Recourse partitioning

sympatric species avoid competition by exploiting different resources.

Traits differ more

within sympatric species than allopatric species.
