Should I Stay or Should I Go? Fission–Fusion Dynamics in Bats
Animal species with fission–fusion dynamics are characterized by variable group size and composition, as individuals move freely among a social network. Patterns consistent with fission–fusion…
Fission-fusion group dynamics in reindeer reveal an increase of cohesiveness at the beginning of the peak rut
TLDR
This study followed the movement of marked animals within an enclosed herd of reindeer Rangifer tarandus during two breeding seasons to test whether variation of the fusion rate or fission rate led to an increase of average group size at the beginning of the peak rut.
Fission-fusion dynamics and group-size-dependent composition in heterogeneous populations.
TLDR
This model makes a testable prediction that composition of flocks are group-size-dependent and do not merely reflect the population level heterogeneity, and predicts that there is a critical group size below which groups are more likely to be homogeneous and contain the abundant type or species.
An interaction mechanism for the maintenance of fission–fusion dynamics under different individual densities
TLDR
This study compared the fission–fusion dynamics of two populations of the live-bearing Atlantic molly that live in adjacent habitats with very different predator regimes, and found surface mollies spent more time being social than cave mollie, and this difference in social time was a result of surface molls being less likely to discontinue social contact and being more likely to resume social contact.
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.
Increased Exploration Capacity Promotes Group Fission in Gregarious Foraging Herbivores
TLDR
This study investigates the effect of group fission on area-restricted search, a search tactic that is commonly used when food distribution is spatially autocorrelated, and finds that groups indeed moved faster and farther over time immediately after than before fission.
Measuring Variation in the Frequency of Group Fission and Fusion from Continuous Monitoring of Group Sizes
TLDR
A method to assess the frequency of fission and fusion from continuous monitoring of group composition is extended, based on the variation in group size within which marked individuals were successively recorded, and the resulting method best described the temporal variation in fissions and fusion frequency.
Multiyear social stability and social information use in reef sharks with diel fission–fusion dynamics
TLDR
This work shows multiyear social stability in sharks and suggests that social foraging with information transfer could provide a generalizable mechanism for the emergence of sociality with group central place foraging.
Predation Risk Shapes Social Networks in Fission-Fusion Populations
TLDR
It is suggested that predation risk influences the fine-scale social structure of prey populations and that the temporal aspects of organisation play a key role in defining social systems.
Short-term group fission processes in macaques: a social networking approach
TLDR
An agent-based model was used to understand the mechanisms underlying group fission in two semi-free-ranging groups of macaques and showed that sub-grouping patterns were mainly influenced by affiliative relationships.

TLDR
The ethnographic record of foragers provides the only direct observations of human behavior in the absence of agriculture, and as such is invaluable for testing hypotheses about human behavioral evolution.
