Summary 1. According to a recent hypothesis, personality traits should form integrative pace‐of‐life syndromes with life‐history traits. Potential that explain variation are immune defence and growth rate. 2. We studied whether boldness, measured as hiding behaviour, is repeatable during ontogeny in the field cricket, Gryllus integer , if it relates efficiency of function (i.e. capacity encapsulate nylon implant), rate, developmental time size an adult. 3. Hiding behaviour was rank‐order...
Understanding the evolutionary mechanisms underlying maintenance of individual differences in behavior and physiology is a fundamental goal ecology evolution. The pace-of-life syndrome hypothesis often invoked to explain such within-population variation. This predicts that behavioral traits are part suite correlated collectively determine an individual's propensity prioritize reproduction or survival. A key assumption this these underpinned by genetic trade-offs among life-history traits:...
Summary Numerous studies over the past decade have reported correlations between elevated levels of anthropogenic noise and a rise in minimum frequency acoustic signals animals living noisy habitats. This pattern appears to be occurring globally, higher pitched been hypothesized adaptive changes that reduce masking by low‐frequency traffic noise. However, sound analysis methods most often used these are prone measurement errors can result false positives. In addition, commonly method...
According to recent studies on animal personalities, the level of behavioral plasticity, which can be viewed as slope reaction norm, varies among individuals, populations, and species. Still, it is conceptually unclear how interaction between environmental variation in cognition affect evolution plasticity expression personalities. Here, we (1) use literature review individual explain population (2) draw together empirically yet nontested, conceptual framework clarify these factors...
Over the last few years, animal personality researchers have called for integrative approaches to study behavioral, immunological, and life-historical traits. This is because life history become implied as part of "pace-of-life" syndromes. Immune defense one traits that been suggested associate with traits, such boldness, mainly behavioral types may differ in parasite encounter rates. Here, we quantified narrow-sense heritabilities (h2 = VA/(VA + VR)) genetic (rA) phenotypic (rP)...
Abstract Age at maturity is a key life history trait involving trade-off between survival risk and reproductive investment, an important factor for population structures. In ectotherms, warming environment may have dramatic influence on development history, but this differ populations. While increasing number of studies examined population-dependent reactions with temperature, few investigated in the context maturation timing. Atlantic salmon, species high conservation relevance, good study...
The study of adaptive individual behavior ("animal personality") focuses on whether individuals differ consistently in (suites correlated) behavior(s) and individual-level is under selection. Evidence for selection acting personality biased toward species where behavioral life-history information can readily be collected the wild, such as ungulates passerine birds. Here, we report estimates repeatability syndrome structure behaviors that an insect (field cricket; Gryllus campestris )...
Abstract Behavioural ecology research increasingly focuses on why genetic behavioural variation can persist despite selection. Evolutionary theory predicts that directional selection leads to evolutionary change while depleting standing variation. Nevertheless, stasis may occur for traits involved in social interactions. This requires tight negative correlations between direct effects (DGEs) of an individual’s genes its own phenotype and the indirect (IGEs) it has conspecifics, as this could...
Repeatability represents a key parameter in ecological and evolutionary research. is underpinned by developmental plasticity genetic variation but may become biased upwards repeatable differences environments to which individuals respond plastically. The extent of upward bias caused the latter mechanism (causing "pseudo-repeatability") important yet rarely investigated We repeatedly assayed behaviour (flight initiation distance) affecting longevity wild cricket population (Gryllus...
The pace-of-life syndrome (POLS) hypothesis predicts associations between life history and ‘risky’ behaviours. Individuals with ‘fast’ lifestyles should develop faster, reproduce earlier, exhibit more risk-prone behaviours, die sooner than those ‘slow’ lifestyles. While support for POLS has been equivocal to date, studies have relied on individual-level (phenotypic) patterns in which genetic trade-offs may be masked by environmental effects phenotypes. We estimated correlations (development,...
The causes and consequences of among-individual variation covariation in behaviours are substantial interest to behavioural ecology, but the proximate mechanisms underpinning this (co)variation still unclear. Previous research suggests metabolic rate as a potential mechanism explain covariation. We measured resting (RMR), boldness exploration western stutter-trilling crickets, Gryllus integer , selected differentially for short fast development over two generations. After applying...
Foraging complexity and competitive social challenges are considered key drivers of human cognition. Yet, we still have a poor understanding the decision-making mechanisms underlying foraging behaviour, especially in contexts. Here, use high-resolution tracking data combination with computational agent-based models to uncover guiding decisions where forage when leave patch. Equipping large groups Finnish ice-fishers competing for resources global positioning systems headcams, analyzing 477...
Abstract Here, we explored a hypothesis from framework proposing that sexual selection plays role in shaping and maintaining consistent among-individual behavioral variation, commonly referred to as personality differences. This suggests parental care may be mechanism linking differences with reproductive fitness. To test this hypothesis, repeatedly measured boldness activity under simulated predation risk male female rainbow kribs, Pelvicachromis pulcher, bi-parental West African cichlid....
Age at maturity is an important life-history trait, often showing sex-specific variation, contributing to diversity in many species. Atlantic salmon (Salmo salar) are excellent model system investigate genetic and environmental factors affecting maturation, yet few laboratory studies have focused on females as they mature later than males, average. Using a 4-year common-garden experiment of salmon, we assessed the influence diet (low-fat vs. control) vgll3 (a candidate gene influencing...
Foraging complexity and competitive social challenges are considered key drivers of human cognition. Yet, the decision-making mechanisms underlying foraging in real world remain unknown. Integrating high-precision GPS tracking video footage from large-scale competitions with cognitive-computational modeling agent-based simulations, we show how foragers integrate socioecological information streams to guide spatial search patch-leaving decisions. Contrasting earlier work, context emerges as a...
