“…Some studies reported a positive correlation between boldness and body mass in fishes (e.g. Magnhagen & Borcherding 2008), some reported no relationship (Kobler et al 2009) while others documented a reverse relationship (e.g. Brown & Braithwaite 2004;Millot et al 2009), which is indeed expected in many state-dependent models involving the asset protection principle (Clark 1994).…”

Reebs 2006), which has for a long time been considered the most homogeneous social structure in fishes (Radakov 1972). Even the classical example of many ethological textbooks, the stereotypic response of male three-spined sticklebacks (Gasterosteus aculeatus) to the red belly of an opponent is very pronounced in some individuals but absent in others: it is so variable that the classical concept of innate releasing mechanisms (sign stimuli) can be questioned (Rowland 1982;Baerends 1985;Bolyard & Rowland 1996).Niko Tinbergen, in his classical work 'On the aims and methods of ethology' (Tinbergen 1963), outlined four questions that are fundamental for our understanding of any behaviour:(1) Causation: What is the cause of the behaviour in question?(2) Function: What is its survival value? (3) Ontogeny: How does it develop? (4) Evolution: How did it evolve?

“…; 93.6 + 10.0 mm, weight 7.5 + 2.5 g, n ¼ 64) were collected in August 2006 with a beach seine in the lakes Fisksjö n and Ä ngersjö n, close to the city of Umeå (63847 0 N; 20817 0 E) in northern Sweden. The two lakes differ in predator regime and we have earlier found behaviour differences in young perch from these two lakes (Magnhagen 2006;Magnhagen & Borcherding 2008). The fish were transported to Umeå Marine Research Center, 45 km south of Umeå, where the experiments were performed.…”

Behavioural syndromes, defined as correlated behaviours in different contexts, have been studied across species and taxa including humans as part of a personality concept. While most studies have focused on solitary individuals, less is known on how shoaling fish compromise between own personality and group behaviour. Risk-taking behaviour in 1-year-old perch (Perca fluviatilis) was observed to compare individual behaviour when in a group and when alone. An experimental design gave the fish the choice between foraging in an open area in the presence of a piscivore and hiding in the vegetation. We quantified the variation accountable by the effect of individuals being in a group, individuals alone and repeated measurements, using hierarchical mixed effects models. Within-group variances were low, but when individuals were later tested alone, individual differences explained most of the variation. Still, the individual best linear unbiased predictors (BLUPs) of time spent in the open area, extracted from the random effects of the mixed effects model, were positively correlated with the corresponding BLUPs when alone. The results indicate that individual behavioural traits are to some degree expressed also within groups. Most fish showed a shyer behaviour when alone, but bolder individuals changed less between treatments than did shyer ones, suggesting a more influential role of bold fish in the group.

“…Stamps & Groothuis 2010a,b). For example, individuals may experience a range of contrasting environmental conditions throughout life (Magnhagen & Borcherding 2008;Sinn et al 2010), and these changes may weaken or even reverse the association between personality and other traits. Detailed investigation of the developmental aspects of personality traits, the effects of genotype by environment interaction, and of genotype/environment correlation on these traits have recently been advocated (e.g.…”

The pace-of-life syndrome (POLS) hypothesis specifies that closely related species or populations experiencing different ecological conditions should differ in a suite of metabolic, hormonal and immunity traits that have coevolved with the life-history particularities related to these conditions. Surprisingly, two important dimensions of the POLS concept have been neglected: (i) despite increasing evidence for numerous connections between behavioural, physiological and life-history traits, behaviours have rarely been considered in the POLS yet; (ii) the POLS could easily be applied to the study of covariation among traits between individuals within a population. In this paper, we propose that consistent behavioural differences among individuals, or personality, covary with life history and physiological differences at the within-population, interpopulation and interspecific levels. We discuss how the POLS provides a heuristic framework in which personality studies can be integrated to address how variation in personality traits is maintained within populations.
