Behavioural traits are often noted to persist after relaxation or removal of associated
selection pressure, whereas it has been observed that morphological traits under similar …

How novel phenotypes evolve is challenging to imagine because traits are often underlain
by numerous integrated phenotypic components, and changes to any one form can disrupt …

Behavioural flexibility might help animals cope with costs of genetic variants under selection,
promoting genetic adaptation. However, it has proven challenging to experimentally link …

Divergence of sexual signals between populations can lead to speciation, yet opportunities
to study the immediate aftermath of novel signal evolution are rare. The recent emergence …

Abstract Theory predicts that compensatory genetic changes reduce negative indirect effects
of selected variants during adaptive evolution, but evidence is scarce. Here, we test this in a …

Circadian rhythms are ubiquitous in nature and endogenous circadian clocks drive the daily
expression of many fitness-related behaviors. However, little is known about whether such …

Acoustic communication is one of the most well-known behavioural traits of the Orthoptera.
Orthopteran insects and the sounds they produce are both extremely diverse, and species …

The effects of within-generation plasticity vs. transgenerational plasticity on trait expression
are poorly understood, but important for evaluating plasticity's evolutionary consequences …

Understanding the connection between personality and fitness is an important topic in both
behavioural and evolutionary ecology. Most of our current knowledge stems from lab-studies …

Associations between heritable polymorphisms and life‐history traits, such as development
time or reproductive investment, may play an underappreciated role in maintaining …
