intraspecific competition


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

intraspecific competition

any limited competition within the same species population for a resource such as food. Not all members of the population may be negatively affected by the competition, resulting in differential ability to survive and reproduce (see FITNESS). see COMPETITION.
