DOI: 10.1007/s00265-017-2293-5
Abstract: The relationship between group size and fitness has attracted much interest, with many attempts made to detect an optimal group size. Group size is determined by the benefits and costs influencing group formation, which also… read more here.

Group size affects spontaneous quantity discrimination performance in wild Western Australian magpies (Gymnorhina tibicen dorsalis)
Sign Up to like & getrecommendations! Published in 2025 at "Animal Cognition"
DOI: 10.1007/s10071-025-01963-0
Abstract: Animals may benefit from the ability to discriminate between quantities in their environment; for example, when choosing between foraging patches differing in food availability or assessing the size of rival groups. Numerous studies utilising spontaneous… read more here.

Decision-making in shoaling: zebrafish integrate cues of familiarity and group size

DOI: 10.1007/s10071-025-02008-2
Abstract: Social groups vary in the benefits that they offer to individuals through characteristics such as group size and composition, and consequently individual animals often exhibit preferences for groups with properties indicating greater benefits for members.… read more here.

Social interaction, and not group size, predicts parasite burden in mammals

DOI: 10.1007/s10682-020-10086-6
Abstract: Although parasitism is often considered a cost of sociality, the evidence is mixed, possibly because sociality is multivariate. Here we contrast the dependence of parasitism costs on major social variables such as group size and… read more here.

DOI: 10.1007/s10764-019-00119-5
Abstract: Intergroup encounters are common in nonhuman primates and can vary from affiliative to aggressive. We extracted data from the literature to test five different hypotheses: 1) where there are group size differences between opposing groups,… read more here.

DOI: 10.1007/s10764-020-00144-9
Abstract: Evolutionary game theory posits that competitive ability affects the initiation of conflicts. When contests occur among groups, competitive ability is generally measured as the size of the group and larger groups are expected to win… read more here.

DOI: 10.1007/s10764-020-00174-3
Abstract: The number of males per group varies substantially in group-living primates, both between and within species. In blue monkeys (Cercopithecus mitis), males may temporarily join groups during annual mating seasons when sexually receptive females are… read more here.

DOI: 10.1007/s42991-020-00041-x
Abstract: Habitat structure and population density have long been considered key factors in determining intraspecific variation in the group size of social ungulates. However, the effect of interaction between habitat structure and population density on group… read more here.

DOI: 10.1016/j.anbehav.2020.08.018
Abstract: Group hunting where two or more individuals chase the same prey occurs in various vertebrate clades. Its evolution has typically been attributed to the resulting increased prey capture rate. Indeed, many studies have documented positive… read more here.
