As the most diverse vertebrate group and a major component of a growing global
aquaculture industry, teleosts continue to attract significant scientific attention. The growth in …

Extreme environmental conditions have profound impacts on sha** the evolutionary
trajectory of organisms. Exposure to these conditions elicits stress responses, that can …

Background Understanding the influence of methodology on results is an essential
consideration in experimental design. In the expanding field of fish microbiology, many best …

Animals inhabiting extreme environments allow the powerful opportunity to examine
adaptive evolution in response to diverse pressures. One such pressure is reduced oxygen …

In recent decades, biologist have focused on the spatiotemporal regulation and function of
genes to understand embryogenesis. It is clear that maternal diet impacts fetal development …

Throughout the evolutionary tree, there are gains and losses of morphological features,
physiological processes, and behavioral patterns. Losses are perhaps nowhere so …

A central question in biology is how naturally occurring genetic variation accounts for
morphological and behavioral diversity within a species. The Mexican tetra, Astyanax …

Extreme environmental features can drive the evolution of extreme phenotypes. Over the
course of evolution, certain environmental changes may be so drastic that they lead to …

Dark caves lacking primary productivity can expose subterranean animals to hypoxia. We
used the surface-dwelling (surface fish) and cave-dwelling (cavefish) morphs of Astyanax …

Apicomplexans are obligate intracellular parasites that have evolved from a free-living,
phototrophic ancestor. They have been reported from marine environmental samples in high …
