Fish biology has been developed for more than 100 years, but some important
breakthroughs have been made in the last decade. Early studies commonly concentrated on …

Triggers and biological processes controlling male or female gonadal differentiation vary in
vertebrates, with sex determination (SD) governed by environmental factors or simple to …

Whole genome duplication (WGD) is a dramatic evolutionary event generating many new
genes and which may play a role in survival through mass extinctions. Paddlefish and …

The bowfin (Amia calva) is a ray-finned fish that possesses a unique suite of ancestral and
derived phenotypes, which are key to understanding vertebrate evolution. The phylogenetic …

The neuronal and neuroendocrine peptides oxytocin (OT) and vasotocin (VT), including
vasopressins, have six cognate receptors encoded by six receptor subtype genes in jawed …

Unlike birds and mammals, many teleosts have homomorphic sex chromosomes, and
