Abstract Abstract. The spider Agelenopsis aperta, exhibits a suite of behavioural traits that are functionally dissimilar but which all potentially could be influenced by inherent levels of 'fear' and 'aggression': agonistic behaviour, territory size, foraging behaviour, and anti-predatory behaviour. Previous findings suggest that in A. aperta, agonistic behaviour and territory size are phenotypically correlated at both the individual and population levels, as are foraging and anti-predator… 

Behavioural syndromes and their fitness consequences in a socially polymorphic spider, Anelosimus studiosus

Predation mediated population divergence in complex behaviour of nine‐spined stickleback (Pungitius pungitius)

The data reject the hypothesis that behavioural syndromes exist as a result of genetic correlations between behavioural traits, and support the contention that different behavioural types can be predominant in populations differing in predation pressure.

The ontogeny of personality traits in the desert funnel‐web spider, Agelenopsis lisa (Araneae: Agelenidae)

It is concluded that behavioral syndromes do not exist in this species, but increased consistency, increasing average trait values, and varying correlations between traits may coincide with developmentally important changes associated with sexual maturation, albeit at different time points in males and females.

On average, boldness and aggression in stickleback were negatively related to each other across the populations, suggesting that behavioural syndromes don't always act as evolutionary constraints.

Individual differences in exploratory and antipredator behaviour in juvenile smallmouth bass (Micropterus dolomieu)

Summary The correlation of individual behaviour in different contexts, known as a behavioural syndrome, constrains the optimization of behaviour within each context. Recent studies reveal that the

This study is a first attempt to relate individualized behaviour to life history variables in a cephalopod mollusc, and the results should contribute to knowledge of how individuals make up populations, a process that is of importance to a number of life sciences, including behavioural, population, fisheries and evolutionary ecology.

Effects of perceived predation risk and social environment on the development of three-spined stickleback (Gasterosteus aculeatus) morphology

Exposure to chemical cues from potential predators did not influence growth or body condition or induce more robust morphological defences, but sticklebacks exposed to predator cues developed longer caudal peduncles and larger eyes as compared with fish from the control treatment, suggesting they might be adaptive.

The Relationships between Behavioural Categories and Social Influences in the Gregarious Big Brown Bat (Eptesicus fuscus)

It is found that Big brown bats exhibit a mean profile relatively unique to other well-documented species, where aggression was linked to increased competitive ability but not to boldness and poor body condition may be a predictor of increased social interactions.
