Decision making in moving animal groups has been shown to be disproportionately influenced by individuals at the front of groups. Therefore, an explanation of state-dependent positioning of individuals within animal groups may provide a mechanism for group movement decisions. Nutritional state is dynamic and can differ between members of the same group. It is also known to drive animal movement decisions. Therefore, we assayed 6 groups of 8 rainbowfish foraging in a flow tank. Half of the fish…

Behavioural consistency and group conformity in humbug damselfish
It is found that individuals were repeatable in their level of activity and exploration, and that this was independent of both absolute size and within-group dominance rank, indicating that animals were behaviourally consistent.
Group Coordination and Decision-Making during Foraging in Meerkats (Suricata suricatta)
Some animal species live in stable social groups and scientists have long wondered how such groups are organized in space and how these groups maintain cohesion and make decisions. Group living
Spatial structure of foraging meerkat groups is affected by both social and ecological factors
Evidence is provided that both the social and physical environment is important for the spatial assortment of meerkats, a social mongoose foraging in cohesive groups, and that meerkat groups display a dynamic spatial structure depending on both the currentSocial and physical environmental.
Risk-taking and locomotion in foraging threespine sticklebacks (Gasterosteus aculeatus): the effect of nutritional stress is dependent on social context
This study links state-dependent individual behaviour to social foraging performance and reinforces the theory that social context is an important modulator of the relationships between physiology and behaviour.
The role of physiological traits in assortment among and within fish shoals
Mechanisms by which physiological traits—particularly those related to metabolism and locomotor performance—may result in phenotypic assortment not only among but also within animal groups are discussed.
Food searching behaviour in adult Atlantic cod Gadus morhua during acoustic training: social learning and leadership within a school.
The study reveals how social learning can facilitate the acoustic training in adult G. morhua, information that may be useful in finding ways to aggregate valuable fish species for environmentally friendly fishing and ranching.
Consequences of temperature and temperature variability on swimming activity, group structure, and predation of endangered delta smelt
Novel insight is provided into the group behaviour of delta smelt, their response to predation, and how prolonged exposure to elevated temperature may induce negative individual and group behaviours causing alterations in predator–prey dynamics is provided.
Injury-mediated decrease in locomotor performance increases predation risk in schooling fish
Investigation in sardine schools under attack from group hunting sailfish in the open ocean found only partial support for the theoretical predictions from current predator-prey models, highlighting the importance of incorporating more realistic predator–prey dynamics into these models.
Drivers of passive leadership in wild songbirds: species-level differences and spatio-temporally dependent intraspecific effects
The importance of understanding the mechanisms behind leading behavior is highlighted and directions for future experimental work are discussed to gain a better understanding of the causes of leadership in natural populations of great tits and blue tits.


Laterality Influences Schooling Position in Rainbowfish, Melanotaenia spp
The authors' results strongly implicate individual laterality in the geometry of school formation, and this general pattern varied depending on the species and sex of the school.
The influence of nutritional state on individual and group movement behaviour in shoals of crimson-spotted rainbowfish (Melanotaenia duboulayi)
It is shown that the internal nutritional state of individual fish affected basic behaviours relating to spatial positioning, and group behaviour reflected the motivations of its individual members in such a way that allowed individuals to fulfil their own behavioural needs whilst still attaining the benefits of grouping.
Vervet (Chlorocebus pygerythrus) Intragroup Spatial Positioning: Dominants Trade-Off Predation Risk for Increased Food Acquisition
The costs and benefits of group-living are not distributed evenly among group members. Individuals that maintain positions on the front, outside edge of the group encounter most predators first, but
Consistency of Leadership in Shoals of Mosquitofish (Gambusia holbrooki) in Novel and in Familiar Environments
It is found that certain individuals consistently occupied front positions in moving groups and also that it was typically these individuals that initiated group decisions, suggesting that being a leader or a follower may to some extent be an intrinsic property of the individual.
Influences of food distribution on fish foraging behaviour
Results indicate that social aspects of fish foraging strategies are flexible, but are also influenced by prior experience with resource distribution.
Correlates of boldness in three-spined sticklebacks (Gasterosteus aculeatus)
The results suggest that, contrary to some previous studies on other animals, bold or shy behaviour in sticklebacks is consistent between contexts.
Cross-shoal variability in the feeding habits of migrating Atlantic cod (Gadus morhua)
These results are the first to document systematic heterogeneous feeding success among members of a free-ranging and migrating fish shoal in the open ocean.
Positioning Behaviour in Roach Shoals: The Role of Body Length and Nutritional State
The results suggest that the initiation of new swimming directions in stationary shoals does not follow the same principles as positioning behaviour in shoals that are already on the move, which could provide a functional explanation for the occurrence of food-deprived fish in front positions.
Hunger-induced foraging behavior of two cyprinid fish: Pseudorasbora parva and Rasbora daniconius
The findings of this study demonstrate that satiation plays an important role in fish foraging that should be considered a significant factor in foraging analysis.
