Group living provides the presence of social information within the group, allowing both male and female members to find and select potential mating partners. Alongside this, living in a group allows for higher reproductive success as individuals have access to a greater number of potential mates, and the possibility to choose between them. [1]
A collective web of Agelena consociata in Uganda.. A social spider is a spider species whose individuals form relatively long-lasting aggregations.Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.
Another cost to group living is stress levels within individuals of a group. Stress levels within group living varies dependent on the size of the colony or group. A large group of animals may suffer larger levels of stress arising from intraspecific food competition. In contrast, smaller groups may have increased stress levels arising from the ...
In opposition to many animal-decision making strategies which encourage individual fitness, group living (or sociality) prioritises an inclusive group fitness. [4] Socioecological factors are thought to influence primate social organisation. For example, the main benefits of group living are hypothesised to be: Improved predator detection.
Theoretical framework is focused on the costs and benefits associated with living in groups in terms of the fitness of each individual compared to living solitarily. Living in groups evolved independently multiple times in various taxa and can only occur if its benefits outweigh the costs within an evolutionary timescale. Thus, animals form ...

Also, participants in multi-male groups have better access to resources such as food and living quarters. However, a major cost to living in a multi-male group is the constant competition for mates, mainly among males but also among females.
For example, in meerkats, larger group size provides a benefit to all the members of that group by increasing survival rates, foraging success and conflict wins. [13] This is because living in groups is better than living alone, and cooperation arises passively as a result of many animals doing the same thing.
