The deer mouse (Peromyscus maniculatus) occupies diverse habitats across its extensive range in North America and shows striking variation in several morphological traits, most notably, tail length29,30,31. At the extreme, deer mice occupying forest habitat can have tails that are 60% longer (appr...
Being too adaptable might lead to a lack of consistency, difficulty in setting firm boundaries, or neglecting one's own needs and principles. 8 How do organisms exhibit adaptive traits? Organisms exhibit adaptive traits through evolutionary changes that enhance their survival and reproduction in specif...

Timing of transitions differed between years, although we found strong cross year genetic correlations in all traits, suggesting that genotypes respond in consistent ways to seasonal cues. Spring and autumn phenology were correlated with lifetime growth, where genotypes that burst leaves early and ...
The mechanism by which a species determines the sex of its offspring has been linked to critical ecological and life-history traits but not to major adaptive radiations, in part because sex-determining mechanisms do not fossilize. Here we establish a previously unknown coevolutionary relationship in...

This suggests that examining meaningful subgroups (e.g., along functional traits such as feeding or habitat requirements) during analysis, rather than “the beetles,” would enhance the ability to detect significant relationships in monitoring data. Certain variables sampled in this study, i.e., ...
Superior physical competence is vital to the adaptive behavioural routines of many animals, particularly those that engage in elaborate sociosexual displays. How such traits evolve across species remains unclear.Recent work suggests that activation of sex steroid receptors in neuromuscular systems is ...
In addition, the importance of sexual selection is demonstrated by a profusion of exaggerated sexually dimorphic traits like male nuptial colour and elaborate bower building by males3. Ecological and sexual selection converge in the cichlid visual system, where trichromatic colour vision, eight different...
