Sexual selection drives the evolution of some of the most exaggerated traits in nature.
Studies on sexual selection often focus on the size of these traits relative to body size, but …

If fitness optima for a given trait differ between males and females in a population, sexual
dimorphism may evolve. Sex-biased trait variation may affect patterns of habitat use, and if …

Understanding the factors that facilitate or constrain establishment of populations in novel
environments is crucial for conservation biology and the study of adaptive radiation …

Throughout the animal kingdom, there are striking differences in the propensity of one sex or
the other to become infected. However, precisely when we should expect males or females …

The slender anole, Anolis apletophallus, is a small arboreal lizard of the rainforest
understory of central and eastern Panama. This species has been the subject of numerous …

Sexual size dimorphism is widespread in nature and often develops through sexual
divergence in growth trajectories. In vertebrates, the growth hormone/insulin-like growth …

The evolution of costly signalling traits has largely focused on male ornaments. However,
our understanding of ornament evolution is necessarily incomplete without investigating the …

Positive allometry has been considered a hallmark of sexual selection whereby larger males
of superior condition develop disproportionately larger ornaments for their body size …

Parasites are a strong selective force that can influence fitness‐related traits. The length of
chromosome‐cap** telomeres can be used to assess the long‐term costs of parasitism …

Sexual size dimorphism is widespread in nature and often develops through sexual
