TLDR
Here, it is outlined how central ideas in behavioural ecology and quantitative genetics can be combined within a single framework based on the concept of 'behavioural reaction norms', facilitating analysis of phenomena usually studied separately in terms of personality and plasticity, thereby enhancing understanding of their adaptive nature.Abstract:
Recent studies in the field of behavioural ecology have revealed intriguing variation in behaviour within single populations. Increasing evidence suggests that individual animals differ in their average level of behaviour displayed across a range of contexts (animal 'personality'), and in their responsiveness to environmental variation (plasticity), and that these phenomena can be considered complementary aspects of the individual phenotype. How should this complex variation be studied? Here, we outline how central ideas in behavioural ecology and quantitative genetics can be combined within a single framework based on the concept of 'behavioural reaction norms'. This integrative approach facilitates analysis of phenomena usually studied separately in terms of personality and plasticity, thereby enhancing understanding of their adaptive nature.read more

The ODD protocol: A review and first update
TL;DR: The definition of ODD is revised to clarify aspects of the original version and thereby facilitate future standardization of ABM descriptions and improves the rigorous formulation of models and helps make the theoretical foundations of large models more visible.
Journal ArticleDOI
Repeatability for Gaussian and non-Gaussian data: a practical guide for biologists.
TL;DR: Two types of repeatability (ordinary repeatability and extrapolated repeatability) are compared in relation to narrow‐sense heritability and two methods for calculating standard errors, confidence intervals and statistical significance are addressed.

Personality and the emergence of the pace-of-life syndrome concept at the population level
Denis Réale,Dany Garant,Murray M. Humphries,Patrick Bergeron,Vincent Careau,Pierre-Olivier Montiglio +5 more
TL;DR: It is proposed that consistent behavioural differences among individuals, or personality, covary with life history and physiological differences at the within-population, interpopulation and interspecific levels.

Quantifying individual variation in behaviour: mixed-effect modelling approaches
TL;DR: An overview of how mixed-effect models can be used to partition variation in, and correlations among, phenotypic attributes into between- and within-individual variance components is provided.
Journal ArticleDOI
Guidelines for estimating repeatability
TL;DR: In this paper, the authors provide guidelines for determining the sample size (number of individuals and number of measurements per individual) required to accurately estimate the intraclass correlation coefficient (ICC).

The measurement of selection on correlated characters
Russell Lande,Stevan J. Arnold +1 more
TL;DR: Measures of directional and stabilizing selection on each of a set of phenotypically correlated characters are derived, retrospective, based on observed changes in the multivariate distribution of characters within a generation, not on the evolutionary response to selection.

Behavioral syndromes: an ecological and evolutionary overview.
TL;DR: The existence of behavioral syndromes focuses the attention of behavioral ecologists on limited (less than optimal) behavioral plasticity and behavioral carryovers across situations, rather than on optimal plasticity in each isolated situation.

Integrating animal temperament within ecology and evolution.
Denis Réale,Simon M. Reader,Simon M. Reader,Daniel Sol,Daniel Sol,Peter T. McDougall,Niels Jeroen Dingemanse +6 more
TL;DR: It is proposed that temperament can and should be studied within an evolutionary ecology framework and provided a terminology that could be used as a working tool for ecological studies of temperament, which includes five major temperament trait categories: shyness‐boldness, exploration‐avoidance, activity, sociability and aggressiveness.
