Primate sociality is an area of primatology that aims to study the interactions between three main elements of a primate social network: the social organisation, the social structure and the mating system. The intersection of these three structures describe the socially complex behaviours and relationships occurring among adult males and ...
Hierarchy results from interactions, group dynamics, and sharing of resources, so group size and composition affect the dominance decisions of high-ranking individuals. For example, in a large group with many males, it may be difficult for the highest-ranking male to dominate all the mating opportunities, so some mate sharing is likely to exist.
In another species of sweat bees, L. calceatum, social phenotype has been predicted by altitude and micro-habitat composition, with social nests found in warmer, sunnier sites, and solitary nests found in adjacent, cooler, shaded locations. Facultatively social bee species, however, which comprise the majority of social bee diversity, have ...
Positions within the hierarchy correlate with territoriality, courtship rate, nest size, aggression, and hormone production. [36] In terms of social structure, Mozambique tilapias engage in a system known as lek-breeding, where males establish territories with dominance hierarchies while females travel between them. Social hierarchies typically ...
However, this is opposite among cassowaries, for example. Among primates, this form of social organization is most common among the nocturnal strepsirrhine species and tarsiers. Solitary-but-social species include mouse lemurs, lorises, and orangutans. [63]
Primates provide perhaps one of the best examples of mutual grooming, due to the intensive research performed regarding their varying lifestyles and the direct variation in the means of social grooming across different species. Among primates, social grooming plays a significant role in animal consolation behavior, whereby the primates engage ...
This example raises the question of how altruistic genes can be passed on if this soldier dies without having any children. [15] Within sociobiology, a social behavior is first explained as a sociobiological hypothesis by finding an evolutionarily stable strategy that matches the observed behavior. Stability of a strategy can be difficult to ...
The three types - the queen, workers, and drones - all serve a specific purpose within the colony. [1] The queen is the reproductive member of the colony. Some ant species will only have one queen, while others will form polygynous colonies of multiple queens, such as Argentine ants Linepithema humile. [2]
