Researchers studying the evolution of animal communication often ask what generates and
maintains signal complexity, but they define and measure complexity in different ways. If …

Sexually selected weapons used to monopolize mating opportunities are predicted to trade-
off with traits used in competition for fertilization. Yet, the limited size range typically found …

When females copulate with multiple males, pre-and post-copulatory sexual selection may
interact synergistically or in opposition. Studying this interaction in wild populations is …

A key focus of ecologists is explaining the origin and maintenance of morphological diversity
and its association with ecological success. We investigate potential benefits and costs of a …

It is common for studies that employ the comparative method for the study of adaptation, that
is, documentation of potentially adaptive across-species patterns of trait–environment or trait …

Male fertilization success depends on investment in both pre-and postcopulatory sexually
selected traits, and considerable attention has recently been paid to quantifying the strength …

Positive genetic covariance between male sexual display traits and fertilizing capacity can
arise through different mechanisms and has important implications for sexual trait evolution …
