...Christian Kropf; Karl Fent; Stephan Fischer; Ayako Casanova; Helmut Segner ABSTRACT Fish gills are a structurally and functionally complex organ at the interface between the organism and the aquatic environment. Gill functions include the transfer of organic molecules, both natural ones...

... salinities, ventilation increased and heart rate fell in the classic manner, while Ṁ O 2 initially declined by ∼50%, with partial restoration by 3 h of hypoxia, and no O 2 debt repayment during recovery. Gill paracellular permeability (measured with [ 14 C] PEG-4000) was 1.4-fold higher in seawater...

... crabs ( Limulus polyphemus ), book gills bear physiologically distinct regions: dorsal and ventral half-lamellae, a central mitochondria-rich area (CMRA) and peripheral mitochondria-poor areas (PMPAs). In the present study, the CMRA and ventral half-lamella exhibited characteristics important...

...Dirk Weihrauch; Michael P. Wilkie; Patrick J. Walsh SUMMARY The diversity of mechanisms of ammonia and urea excretion by the gills and other epithelia of aquatic organisms, especially fish and crustaceans, has been studied for decades. Although the decades-old dogma of `aquatic species excrete...

... rainbow trout tissues responded to high environmental ammonia. To determine whether or not Rh proteins may also be involved in CO 2 transport in rainbow trout,we examined the effects of a 12 h exposure to external hypercapnia (1%CO 2 in air) on Rh mRNA expression in the gill, skin and erythrocytes...

... for a successful terrestrial invasion. Crabs can actively uptake or excrete ions upon salinity change, and the gills play a major role among the osmoregulatory organs. Several enzymes are involved in the osmoregulatory process, including Na + ,K + -ATPase and V-type H + -ATPase (V-H + -ATPase). Na + ,K + -ATPase...
