Group foraging can thus reduce an animal's foraging payoff. [27] Group foraging may be influenced by the size of a group. In some species like lions and wild dogs, foraging success increases with an increase in group size then declines once the optimal size is exceeded. A myriad number of factors affect the group sizes in different species.
In ethology, fission–fusion society is one in which the size and composition of the social group change as time passes and animals move throughout the environment; animals merge into a group (fusion)—e.g. sleeping in one place—or split (fission)—e.g. foraging in small groups during the day.
A study conducted on the Alaskan moose shows that with increasing group size, there is a decrease in foraging efficiency. [32] This is result of increased social aggression in the groups, as the individuals of the group spent most of its time in alert-alarm postures, thus spending less time foraging and feeding, reducing its foraging efficiency.

The notice follows the recent sudden deaths of three healthy dogs who went swimming in Lady Bird Lake in Austin, Texas. Unfortunately for the three owners, it was an avoidable death for their pets.
Foraging is the oldest subsistence pattern, with all human societies relying on it until approximately 10,000 years ago. [2] Foraging societies obtain the majority of their resources directly from the environment without cultivation. Also known as Hunter-gatherers, foragers may subsist through collecting wild plants, hunting, or fishing. [1]
After years of terrible treatment, some brave dogs recently had the time of their lives. Beagle Freedom Project, a U.S. based non-profit organization, worked with several groups in South Korea to ...
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 ...
