Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Increasing turbidity in streams and rivers near human activity is cause for environmental
concern, as the ability of aquatic organisms to use visual information declines. To investigate …

Once recombination is halted between the X and Y chromosomes, sex chromosomes begin
to differentiate and transition to heteromorphism. While there is a remarkable variation …

Glucocorticoids (GCs) are produced by the adrenal glands and circulate in the blood to
coordinate organismal physiology. In addition, different tissues may independently regulate their …

Loss of recombination between sex chromosomes often depletes Y chromosomes of
functional content and genetic variation, which might limit their potential to generate adaptive …

The guppy sex chromosomes show an extraordinary diversity in divergence across
populations and closely related species. In order to understand the dynamics of the guppy Y …

To determine the visual sensitivities of an organism of interest, quantitative reverse
transcription–polymerase chain reaction (qRT–PCR) is often used to quantify expression of the light‐…

Sensory systems are tuned by selection to maximize organismal fitness in particular
environments. This tuning has implications for intraspecies communication, the maintenance of …

African cichlids are well known for their adaptive radiations, but it is now apparent that they
also harbor an extraordinary diversity of sex chromosome systems. In this study, we …

The degree of divergence between the sex chromosomes is not always proportional to their
age. In poeciliids, four closely related species all exhibit a male heterogametic sex …
