Sex steroid hormones play important roles in fish sex differentiation, gonadal development
and secondary sexual characteristics. Olive flounder Paralichthys olivaceus is a valuable …

Salinity is a major ecological factor in the marine environment, and extremely important for
the survival, development, and growth of fish. In this study, gill transcriptomes were …

Although genes with similar expression patterns are sometimes found in the same genomic
regions, almost nothing is known about the relative organization in genomes of genes and …

Across the animal kingdom there are myriad forms within a sex across, and even within,
species, rendering concepts of universal sex traits moot. The mechanisms that regulate the …

The ever-increasing use of synthetic hormones, especially progestins, for medical
applications has drawn growing concerns due to their potential endocrine disrupting effects …

In fishes, the availability of taurine is regulated during ontogenetic development, where its
endogenous synthesis capacity is species dependent. Thus, different pathways and …

The idea of “smart is sexy,” meaning superior cognition provides competitive benefits in
mate choice and, therefore, evolutionary advantages in terms of reproductive fitness, is both …

Sexual dimorphism often results from hormonally regulated trait differences between the
sexes. In sex-role-reversed vertebrates, females often have ornaments used in mating …

Sexual dimorphism, the divergence in morphological traits between males and females of
the same species, is often accompanied by sex-biased gene expression. However, the …

The neuroplastic mechanisms in the fish brain that underlie sex reversal remain unknown.
Gonadotropin-releasing hormone 3 (GnRH3) neurons control male reproductive behaviours …
