Consistent individual differences (CIDs) in behavior are a widespread phenomenon in
animals, but the proximate reasons for them are unresolved. We discuss evidence for the …

The study of phenotypic evolution should be an integrative endeavor that combines different
approaches and crosses disciplinary and phylogenetic boundaries to consider complex …

Although correlations have frequently been observed between specific physiological and
behavioural traits across a range of animal taxa, the nature of these associations has been …

Adult hippocampal neurogenesis is an unusual case of brain plasticity, since new neurons
(and not just neurites and synapses) are added to the network in an activity-dependent way …

Animal personalities or behavioural syndromes are consistent and/or correlated behaviours
across two or more situations within a population. Social insect biologists have measured …

Circadian rhythms influence most of our life activities, notably getting up and going to sleep
every day. The new edition of this book delves into the mechanisms surrounding how these …

1. Empirical testing of optimal foraging models for breath-hold divers has been difficult. Here
we report data from sound and movement recording DTags placed on 23 short-finned pilot …

Repeatability studies are gaining considerable interest among physiological ecologists,
particularly in traits affected by high environmental/residual variance, such as whole-animal …

The number of studies investigating links between among-individual differences in
metabolic rate (MR) and behavior has grown dramatically in the past several years. A major …

1. Data were compiled from the literature and our own studies on 24 ant species to
characterise the effects of body size and temperature on forager running speed. 2. Running …
