Multicellular organisms display an enormous range of life history (LH) strategies and present
an evolutionary conundrum; despite strong natural selection, LH traits are characterized by …

Sexual selection drives rapid phenotypic diversification of mating traits. However, we know
little about the causative genes underlying divergence in sexually selected traits. Here, we …

Developmental phenotypic changes can evolve under selection imposed by age-and size-
related ecological differences. Many of these changes occur through programmed …

Adaptation to different salinities can drive and maintain divergence between populations of
aquatic organisms. Anadromous and stream ecotypes of threespine stickleback …

Recent genetic and genomic studies have revealed tremendous diversity in sex
chromosomes across diverse taxa. Closely related species with different sex chromosomes …

In most fishes, the number of offspring increases with maternal body size. Although this size‐
fecundity relationship often varies among species as a result of the coevolution of life‐history …

Selection can vary geographically across environments and temporally over the lifetime of
an individual. Unlike geographic contexts, where different selective regimes can act on …

Adaptive phenotypes are shaped by a combination of genetic and environmental forces, but
how they interact remains poorly understood. Here, we utilize the cichlid oral jaw apparatus …

Sex chromosomes rapidly turn over in several taxonomic groups. Sex chromosome turnover
is generally thought to start with the appearance of a new sex-determining gene on an …

Bighead carp (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix)
are genetically close aquaculture fish in the Cyprinidae, which have been confirmed to hold …
