Sexual selection has resulted in some of the most captivating features of insects, including
flashy colors, bizarre structures, and complex pheromones. These features evolve in …

Urbanisation can affect mating opportunities and thereby alter inter‐and intra‐sexual
selection pressures on sexual traits. Biotic and abiotic urban conditions can influence an …

Why do males and females frequently differ so markedly in body size and morphology? Sex,
Size, and Gender Roles is the first book to investigate the genetic, developmental, and …

Two seemingly opposite evolutionary patterns of clinal variation in body size and associated
life history traits exist in nature. According to Bergmann's rule, body size increases with …

Males and females share most of their genomes and express many of the same traits, yet the
sexes often have markedly different selective optima for these shared traits. This sexually …

We investigated four predictions about how temperature, photoperiod and sex affect the life
history plasticity and foraging activity of a damselfly.(i) As predicted, increased temperatures …

Our understanding of selection in nature stems mainly from whole-season and cross-
sectional estimates of selection gradients. These estimates suggest that selection is …

In some cases male animals engage in aggressive contests for access to females, in others
they adopt more passive strategies and invest in traits that assist them in detecting females …

Selective regimes and phenotypic optima could either change smoothly and in a clinal
fashion or be spatially organized in a more unpredictable mosaic pattern over the …

The balance of selection acting through different fitness components (eg fecundity, mating
success, survival) determines the potential tempo and trajectory of adaptive evolution. Yet …
