Animals across vertebrate taxa form social communities and often exist as fission–fusion groups. Central place foragers (CPF) may form groups from which they will predictably disperse to forage, either individually or in smaller groups, before returning to fuse with the larger group. However, the function and stability of social associations in predatory fish acting as CPFs is unknown, as individuals do not need to return to a shelter yet show fidelity to core areas. Using dynamic social…

Social dynamics and individual hunting tactics of white sharks revealed by biologging
Social foraging, where animals forage in groups, takes many forms but is less studied in marine predators as measuring social associations in the wild is challenging. We used biologging (activity,
Non-random Co-occurrence of Juvenile White Sharks (Carcharodon carcharias) at Seasonal Aggregation Sites in Southern California
Many terrestrial and aquatic taxa are known to form periodic aggregations, whether across life history or solely during specific life stages, that are generally governed by the availability and
Social Network Analysis Reveals the Subtle Impacts of Tourist Provisioning on the Social Behavior of a Generalist Marine Apex Predator
Shark dive ecotourism is a lucrative industry in many regions around the globe. In some cases, sharks are provisioned using bait, prompting increased research on how baited dives influence shark
Movements and residency of Caribbean reef sharks at a remote atoll in Belize, Central America
TLDR
Analysis of spatial use patterns of 77 Caribbean reef sharks at Lighthouse Reef Atoll, Belize found a high degree individual variation in spatial use of the atoll, but there were significant differences in residency and activity space between sexes, with females being overall more resident.
Residency and movement patterns of adult Port Jackson sharks (Heterodontus portusjacksoni) at a breeding aggregation site.
TLDR
Investigation of the residency and movement patterns of Port Jackson sharks Heterodontus portusjacksoni at a breeding aggregation site in Jervis Bay, south-eastern Australia using passive acoustic telemetry found strong preferences for particular reefs within and between breeding seasons, suggesting that males may be engaging in territorial behaviour.

Provisioning activities in wildlife tourism often lead to short-term animal aggregations during the feeding events. However, the presence of groups does not necessarily mean that individuals interact
Temporal stability of chimpanzee social culture
TLDR
It is shown that chimpanzees adhere to arbitrary group-specific handclasp preferences that cannot be explained by genetics or the ecological environment, indicating that human culture, including its arbitrary social conventions and long-term stability, is rooted in the authors' evolutionary history.

The importance of fission–fusion social group dynamics in birds
TLDR
Investigating the interaction between social structure and environmental covariates can promote a deeper understanding of the evolution of social behaviour and the adaptive value of group living, as well as having important consequences for applied research.
Bats are able to maintain long-term social relationships despite the high fission–fusion dynamics of their groups
TLDR
It is shown that in two wild Bechstein's bat colonies with high fission–fusion dynamics, individuals of different age, size, reproductive status and relatedness maintain long-term social relationships, which may shed new light on the link between social complexity and social cognition in mammals.
Social communities and spatiotemporal dynamics of association patterns in estuarine bottlenose dolphins
TLDR
It is found that habitat “narrowness” may be a major driving force behind the sociality observed in a bottlenose dolphin population in a linear estuarine system, the Indian River Lagoon, Florida, and that social structure was shaped by an individual's ranging patterns and by social processes including preference and avoidance behavior.
Across-year social stability shapes network structure in wintering migrant sparrows.
TLDR
It is suggested that a surprising level of social fidelity across years leads to repeatable patterns of social network structure in migratory populations.
Evidence for non-random co-occurrences in a white shark aggregation
TLDR
It is shown, for the first time, that white sharks form non-random associations with conspecifics, and new insights are provided into the aggregatory behaviour of white sharks at a seal colony.
Sex and social networking: the influence of male presence on social structure of female shark groups
TLDR
These results are the first to demonstrate the disruptive influence that male and novel females have on weak female shark social interactions; conversely, aggregations demonstrating relatively strong temporally stable social bonds are particularly resilient to potential male harassment and novel (female) intruders.
Consistent sociality but flexible social associations across temporal and spatial foraging contexts in a colonial breeder.
TLDR
It is found that social associations varied in a context-dependent manner, highlighting thatSocial associations are most prevalent during foraging and in regions expected to provide clustered resources and that individuals can adjust their social behaviours to match experienced conditions.

TLDR
Assessment of the space use and activity levels of a marine predator, the Caribbean reef shark, in coastal regions of Eleuthera, The Bahamas over a 60-day period using acoustic telemetry indicated C. perezi primarily occupied the outer reef shelf and were rarely detected on the interior of the reef.
