What is resource partitioning in biology?
Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche. In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another.
What is character displacement in biology?
“Ecological character displacement” refers to trait evolution stemming from selection to lessen resource competition between species and therefore acts on traits associated with resource use (e.g., morphological structures such as beaks and jaws; Slatkin, 1980; Schluter, 2001).
What is resource partitioning in an ecosystem?
Resource partitioning or niche differentiation (a process of natural selection that will force competitors to use resources differently) is a way to avoid competition between species and allow for coexistence.
Is character displacement an example of resource partitioning?
Character displacement is an evolutionary adaptation in a heritable trait, caused by resource partitioning.
What is characteristic displacement?
Character displacement is the term used to describe an evolutionary change that occurs when two similar species inhabit the same environment. Under such conditions, natural selection favors a divergence in the characters–morphology, ecology, behavior, or physiology–of the organisms.
How do competitive exclusion and character displacement differ?
Character displacement occurs when similar species that live in the same geographical region and occupy similar niches differentiate in order to minimize niche overlap and avoid competitive exclusion.
Which of the following is an example of partitioning of resources?
The anole lizards found on the island of Puerto Rico are a good example of resource partitioning. In this group, natural selection has led to the evolution of different species that make use of different resources. The figure below shows resource partitioning among 11 species of anole lizards.
