Data from: Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator

Stephen C. Votier, Annette L. Fayet, Stuart Bearhop, Thomas W. Bodey, Bethany L. Clark, James Grecian, Tim Guilford, Keith C. Hamer, Jana W.E. Jeglinski, Greg Morgan, Ewan Wakefield, Samantha C. Patrick & Jana W. E. Jeglinski
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications. In long-lived animals, foraging ability develops with age, but we know little about the ontogeny of individuality in foraging. Here we use precision global positioning system (GPS) loggers to examine how individual foraging site fidelity (IFSF), a common component of foraging specialization, varies between breeders, failed breeders and immatures in a...

Data from: Family network size and survival across the lifespan of female macaques

Lauren J. N. Brent, Angelina Ruiz Lambides & Michael L. Platt
Two decades of research suggest social relationships have a common evolutionary basis in humans and other gregarious mammals. Critical to the support of this idea is growing evidence that mortality is influenced by social integration, but when these effects emerge and how long they last is mostly unknown. Here, we report in adult female macaques that the impact of number of close adult female relatives, a proxy for social integration, on survival is not experienced...

Data from: Evolutionary divergence in life history traits among populations of the Lake Malawi cichlid fish Astatotilapia calliptera

Paul J. Parsons, Jon R. Bridle, Lukas Rüber & Martin J. Genner
During the early stages of adaptive radiation, populations diverge in life history traits such as egg size and growth rates, in addition to eco-morphological and behavioral characteristics. However, there are few studies of life history divergence within ongoing adaptive radiations. Here, we studied Astatotilapia calliptera, a maternal mouthbrooding cichlid fish within the Lake Malawi haplochromine radiation. This species occupies a rich diversity of habitats, including the main body of Lake Malawi, as well as peripheral...

Data from: Multichannel feeding by spider functional groups is driven by feeding strategies and resource availability

Matthew J. Perkins, Richard Inger, Stuart Bearhop & Dirk Sanders
Multichannel feeding, whereby consumers feed across resource channels such as upon herbivore and detritivore resources, acts to link discrete compartments of a food web with implications for ecosystem functioning and stability. Currently however, we have little understanding which feeding strategies of consumers underlie multichannel feeding. We therefore link spider functional group and resource density-dependent or density-independent feeding strategies to multichannel feeding by quantifying not only consumer diet, but also the relative availability of resources. Here...

Data from: Carotenoid coloration is related to fat digestion efficiency in a wild bird

Christina Madonia, Pierce Hutton, Mathieu Giraudeau & Tuul Sepp
Some of the most spectacular visual signals found in the animal kingdom are based on dietarily derived carotenoid pigments (which cannot be produced de novo), with a general assumption that carotenoids are limited resources for wild organisms, causing trade-offs in allocation of carotenoids to different physiological functions and ornamentation. This resource trade-off view has been recently questioned, since the efficiency of carotenoid processing may relax the trade-off between allocation toward condition or ornamentation. This hypothesis...

Data from: Increased prenatal maternal investment reduces inbreeding depression in offspring

Kate E. Ihle, Pascale Hutter & Barbara Tschirren
Inbreeding depression refers to the reduction of fitness that results from matings between relatives. Evidence for reduced fitness in inbred individuals is widespread, but the strength of inbreeding depression varies widely both within and among taxa. Environmental conditions can mediate this variation in the strength of inbreeding depression, with environmental stress exacerbating the negative consequences of inbreeding. Parents can modify the environment experienced by offspring, and have thus the potential to mitigate the negative consequences...

Data from: Testing the stability of behavioural coping style across stress contexts in the Trinidadian guppy

Thomas M. Houslay, Maddalena Vierbuchen, Andrew J. Grimmer, Andrew J. Young & Alastair J. Wilson
Within populations, individuals can vary in stress response, a multivariate phenomenon comprising neuroendocrine, physiological and behavioural traits. Verbal models of individual stress “coping style” have proposed that the behavioural component of this variation can be described as a single axis, with each individual's coping style being consistent across time and stress contexts. Focusing on this behavioural component of stress response and combining repeated measures of multiple traits with a novel multivariate modelling framework, we test...

Data from: Phenotypic and genetic integration of personality and growth under competition in the sheepshead swordtail, Xiphophorus birchmanni

Kay Boulton, Craig A. Walling, Andrew J. Grimmer, Gil G. Rosenthal, Alastair Wilson & Alastair J. Wilson
Competition for resources including food, physical space, and potential mates is a fundamental ecological process shaping variation in individual phenotype and fitness. The evolution of competitive ability, in particular social dominance, depends on genetic (co)variation among traits causal (e.g., behavior) or consequent (e.g., growth) to competitive outcomes. If dominance is heritable, it will generate both direct and indirect genetic effects (IGE) on resource-dependent traits. The latter are expected to impose evolutionary constraint because winners necessarily...
