...Milica Mandic; William Joyce; Steve F. Perry ABSTRACT The hypoxia-inducible factor (HIF) pathway is a key regulator of cellular O 2 homeostasis and an important orchestrator of the physiological responses to hypoxia (low O 2 ) in vertebrates. Fish can be exposed to significant and frequent changes...

...Corrine N. Jacobs; Roi Holzman ABSTRACT Suction feeding is a widespread prey capture strategy among aquatic vertebrates. It is almost omnipresent across fishes, and has repeatedly evolved in other aquatic vertebrates. By rapidly expanding the mouth cavity, suction feeders generate a fluid flow...

...Kristin M. O'Brien Summary Mitochondrial biogenesis is induced in response to cold temperature in many organisms. The effect is particularly pronounced in ectotherms such as fishes, where acclimation to cold temperature increases mitochondrial density. Some polar fishes also have exceptionally high...

...Christopher P. J. Sanford; George V. Lauder ABSTRACT Osteoglossomorph fishes are characterized by the possession of three sets of jaws used during the capture, maceration and swallowing of prey. One of these jaw systems is a remarkable tongue-bite apparatus used during the intraoral crushing...

...Johannes Piiper; Peter Scheid; Steven F. Perry; George M. Hughes ABSTRACT Calculations of the effective O 2 conductance (diffusing capacity or transfer factor, D eff ) of fish gills, obtained from experimental data on gill O 2 exchange, were compared with the predicted O 2 -exchange properties...

... efficiency may more accurately depict the actual process of respiration if time dependent water velocities are incorporated with frequency components in the 1 –30 Hz range. Scheid & Piiper (1976 , p. 36), in a discussion of factors that may limit gas exchange in fish gills, note that ‘unsteady water...
