The costs and benefits of group membership vary with the size of groups, and individuals are expected to modify their choice of groups in response to ecological factors such as food availability and predation risk. We experimentally examined context-dependent group size choice in a shoaling fish, the banded killifish, Fundulus diaphanus, by using nondirectional odour cues to simulate a food source or a successful attack by a predator (food or alarm treatments) in the laboratory. Group sizes… Expand

Figures from this paper

Individual consistency and context dependence in group-size preference of Eurasian perch
TLDR
The results highlight the importance of considering environmental context when studying social behaviour in obligate social fish, and show the complexity of the concept of sociability as a personality trait by demonstrating context dependence in individual consistency in social behaviour. Expand
Context-dependent group size preferences in large shoals of three-spined sticklebacks
TLDR
Group size preferences in the three-spined stickleback, Gasterosteus aculeatus, a small fish that forms large shoals in nature are examined, finding significant discrimination up to numerical contrasts of 40:60 and preferences for the larger shoal decreased with decreasing group size differences. Expand
Individual vs. social learning of predator information in fish: does group size affect learning efficacy?
TLDR
This study highlights the potentially conflicting information that may be perceived by social individuals during both individual and social predation learning, and hypothesizes that the dilution of risk due to the increase of group size balanced the increased of tutor-to-observer ratio when observers directly interacted with tutor(s). Expand
Balancing the Dilution and Oddity Effects: Decisions Depend on Body Size
TLDR
The results suggest that predation risk and individual body size act together to influence shoaling decisions, and large fish preferred shoaling with size-matched individuals, while small fish demonstrated no preference. Expand
Shoal Choice in Swordtails when Preferences Conflict
Individuals obtain a range of benefits from aggregating with others. Evidence suggests that group size and the phenotypic characteristics of potential group mates are both important attributesExpand
To group or not to group: Effect of prolonged exposure to predation and resource availability on the shoaling behaviour of zebrafish (Danio rerio)
TLDR
It is shown that shoaling behaviour is also shaped by previous experience of fish to predation and food resource availability, and prolonged exposure to varying predation pressure and resource availability can together influence shoaling tendencies of fish even when such pressures are relaxed. Expand
Balancing the response to predation—the effects of shoal size, predation risk and habituation on behaviour of juvenile perch
TLDR
The results suggest that perch may adjust boldness behaviour to group size and predation risk independently and vigilance might be particularly effective in groups of two due to the intense monitoring and detailed response to changing levels of risk. Expand
Behavioral adjustments to prior predation experience and food deprivation of a common cyprinid fish species vary between singletons and a group
TLDR
It is demonstrated that behavioral adjustment of qingbo was closely related to the size of the group, which might be due to differences in the predation risk and food competition. Expand
Discrimination of group numerousness under predation risk in anuran tadpoles
TLDR
The results suggest that in anuran larvae the capacity to discriminate between quantities is limited to small numbers, supporting aggregation as a major anti-predator behaviour in bufonids, while frog tadpoles showed a preference for the smaller groups, though in predator-free trials only, probably associated with lower intra-specific competition. Expand
Effects of group size on school structure and behaviour in yellow-eyed mullet Aldrichetta forsteri.
TLDR
It is suggested that a more collaborative approach involving both group size and rules pertaining to nearest-neighbour interactions affects collective behaviours in this species, challenging traditional theories based on either local or global properties as key drivers of group structure. Expand

Predator preferences for attacking particular prey group sizes: consequences for predator hunting success and prey predation risk
TLDR
Per capita predation risk is lower than in small shoals, and joining larger shoals should be advantageous for individual guppies, but cichlids would do better in terms of hunting success by attacking small rather than large shoals. Expand
The social organization of free‐ranging fish shoals
TLDR
No evidence was found that shoals might break up into sub-units of individuals that are more phenotypically assorted than their original shoals, and the mechanisms by which assortative groups may arise and the consequences of low group fidelity for the evolution of cooperative behaviour are discussed. Expand
Animal group forces resulting from predator avoidance and competition minimization
A new model to explain animal spacing, based on a trade-off between foraging efficiency and predation risk, is derived from biological principles. The model is able to explain not only the generalExpand
Safety in numbers: shoal size choice by minnows under predatory threat
TLDR
Although responses were highly variable, minnows displayed an ability to choose between shoal sizes even when size differences were small, preferring the larger shoal whenever a size preference was shown. Expand
Antipredator benefits of schooling behaviour in a cyprinodontid fish, the banded killifish (Fundulus diaphanus)
TLDR
Individual risk of being attacked and killed by a fish predator declined with increasing killifish school size in a manner closely predicted by the dilution hypothesis, and straying from a school has an associated increased risk of mortality to predation, which selects for schooling behaviour. Expand
Predator avoidance and school size in a cyprinodontid fish, the banded killifish (Fundulus diaphanus Lesueur)
TLDR
The results fo not support the proposed early predator warning function of social groups, which predicts an asymptotically increasing flight reaction distance with increasing group size, but fish in larger and safer groups may detect an approaching predator sooner but delay their flight response, thereby permitting their individual members to spend more time assessing the nature of the threat before escaping.

TLDR
It is suggested that fish density acts as a constraint on shoal choice, influencing both shoal size and composition, and has implications for studies on information transfer and reciprocal altruism within populations. Expand
The influence of hunger, shoal size and predator presence on foraging in bluntnose minnows
TLDR
In bluntnose minnows, Pimephales notatus, in shoals of different sizes and at three levels of hunger, foraging was affected significantly by shoal size, predator presence and hunger. Expand
The adaptive significance of schooling as an anti-predator defense in fish
TLDR
Schooling may not be an equally appropriate defence against all predators and the phylogenetic origins of populations or species can lead to additional genetic constraints, so behavioural ecologists will increasingly focus on how interactions between such con straints govern the evolution of behaviour.

The scent of death: Chemosensory assessment of predation risk by prey animals
TLDR
This paper provides an exhaustive review of the literature on the responses of prey to predator chemosensory cues, primarily in tabular form, and highlights the most important studies on predator activity level and diet. Expand
