TLDR
It is argued that a major source of this inconsistency is the influence of environmental stressors, which seem capable of revealing, masking, or modulating covariation in physiological and behavioural traits.Abstract:
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 shown to vary. Here we argue that a major source of this inconsistency is the influence of environmental stressors, which seem capable of revealing, masking, or modulating covariation in physiological and behavioural traits. These effects appear to be mediated by changes in the observed variation of traits and differential sensitivity to stressors among phenotypes. Considering that wild animals routinely face a range of biotic and abiotic stressors, increased knowledge of these effects is imperative for understanding the causal mechanisms of a range of ecological phenomena and evolutionary responses to stressors associated with environmental change.read more

Does individual variation in metabolic phenotype predict fish behaviour and performance
TL;DR: It is suggested that a more integrative approach is now required to fully understand how the environment can modulate individual performance via effects on metabolic phenotypes encompassing SMR, MMR and AS.
Journal ArticleDOI
Environmental enrichment for fish in captive environments: effects of physical structures and substrates
TL;DR: It is found that enrichment can affect several aspects of the biology of captive fish, for example, aggression, stress, energy expenditure, injury and disease susceptibility, and it is clear that just addition of structure is not a solution to all problems in fish rearing.

Fish swimming in schools save energy regardless of their spatial position

TL;DR: It is suggested that the benefits of membership in moving groups may be more strongly linked to reducing the costs of locomotion than previously appreciated.

Demystifying animal 'personality' (or not): why individual variation matters to experimental biologists.
TL;DR: Understanding how and why behavioural traits evolve requires linking repeatable inter-individual behavioural differences with core aspects of physiology and evolutionary biology, and some of the benefits of estimating variation in phenotypic traits at the inter- and intra-individual levels are highlighted.

TL;DR: A review of the ecological impacts of recent climate change exposes a coherent pattern of ecological change across systems, from polar terrestrial to tropical marine environments.

Ecological and Evolutionary Responses to Recent Climate Change
TL;DR: Range-restricted species, particularly polar and mountaintop species, show severe range contractions and have been the first groups in which entire species have gone extinct due to recent climate change.

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.

TL;DR: This Discussion focuses on the part of the history of thermal evolution and its role in climate change that has an impact on human well-being.

Behavioural reaction norms: animal personality meets individual plasticity
TL;DR: 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.
