The Cahuilla, also known as ʔívil̃uqaletem or Ivilyuqaletem, are a Native American people of the various tribes of the Cahuilla Nation, living in the inland areas of southern California. [2] Their original territory encompassed about 2,400 square miles (6,200 km 2 ).
Foraging strategy must provide the most benefit for the lowest cost – it is a balance between nutritional value and energy required. The currency of optimal foraging theory is energy because it is an essential component for organisms, but it is also the downfall of optimal foraging theory in regard to archaeology. [26]
Bruce Winterhalder [16] incorporates food-sharing among groups into the diet breadth model derived from optimal foraging theory as a means to reduce risk. Risk is measured in this model as a measure of the probability that a forager's net acquisition rate (NAR) falls below a minimum value, such as a threshold for starvation.
As an optimal foraging model, the Ideal Free Distribution predicts that the ratio of individuals between two foraging sites will match the ratio of resources in those two sites. This prediction is similar to the Matching Law of individual choice, which states that an individual's rate of response will be proportional to the positive ...

Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. [1] Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives.
Central place foraging (CPF) theory is an evolutionary ecology model for analyzing how an organism can maximize foraging rates while traveling through a patch (a discrete resource concentration), but maintains the key distinction of a forager traveling from a home base to a distant foraging location rather than simply passing through an area or travelling at random.
[6] [7] It has been argued that frequency-dependent predation is predicted from optimal foraging theory. [8] In particular the contingency model predicts that in some circumstances the most profitable resource should be eaten at the expense of the less profitable resources, and that this decision is based on the absolute density of the most ...
