Indirect genetic effects increase the heritable variation available to selection and are largest for behaviors: a meta-analysis
The evolutionary potential of traits is governed by the amount of heritable variation available
to selection. While this is typically quantified based on genetic variation in a focal individual …

Sea anemones (Actinia equina) show consistent individual differences in boldness and thoroughness but lack a behavioural syndrome
S Simpson, M Briffa - Proceedings of the Royal Society B, 2024 - royalsocietypublishing.org
Behavioural syndromes are suites of behaviours that corelate between-individuals but the
same behaviours may also show within-individual correlations owing to state dependency or …

Ontogeny shapes individual dietary specialization in female European brown bears (Ursus arctos)
Individual dietary specialization, where individuals occupy a subset of a population's wider
dietary niche, is a key factor determining a species resilience against environmental change …

The incubation environment does not explain significant variation in heart rate plasticity among avian embryos
The conditions an organism experiences during development can modify how they
plastically respond to short-term changes in their environment later in life. This can be …

Variation in embryonic metabolic reaction norms and the role of the environment
Early developmental environments can shape how organisms respond to later
environments, but despite the potential for this phenomenon to alter the evolution of …

Genetic Variation in Male Aggression Is Influenced by Genotype of Prior Social Partners in Drosophila melanogaster
Social behaviors can be influenced by the genotypes of interacting individuals through
indirect genetic effects (IGEs) and can also display developmental plasticity. We investigated …

The effect of repeated measurements and within-individual variance on the estimation of heritability: a simulation study
The estimation of heritability is a common practice in the field of ecology and evolution.
Heritability of the traits is often estimated using one single measurement per individual …
