scramble competition
In ecology, scramble competition refers to a situation in which a resource is accessible to all competitors (that is, it is not monopolizable by an individual or group). However, since the particular resource is usually finite, scramble competition may lead to decreased survival rates for all competitors if the resource is used to its carrying capacity. Scramble competition is also defined as “a finite resource (is ) shared equally amongst the competitors so that the quantity of food per individual declines with increasing population density”.〔Den Berg, V., Rossing, W., and Grasman, J. (2006). “Contest and Scramble Competition and the Carry-Over Effect in Globodera spp. In Potato-Based Crop Rotations Using an Extended Ricker Model”. Journal of Nematology, 38(2):210-220.〕 A further description of scramble competition is “competition for a resource that is inadequate for the needs of all, but which is partitioned equally among contestants, so that no competitor obtains the amount it needs and all would die in extreme cases.”
==Types of intraspecific competition==
Researchers recognize two main forms of intraspecific competition, where members of a species are all using a shared resource in short supply. These are contest competition and scramble competition.〔
