...Chris M. Wood; Ilan M. Ruhr; Kevin L. Schauer; Yadong Wang; Edward M. Mager; M. Danielle McDonald; Bruce Stanton; Martin Grosell ABSTRACT Freshwater- and seawater-acclimated Fundulus heteroclitus were exposed to acute hypoxia (10% air saturation, 3 h), followed by normoxic recovery (3 h). In both...

...Kelly D. Hannan; Jodie L. Rummer ABSTRACT Aquatic acidification, caused by elevating levels of atmospheric carbon dioxide (CO 2 ), is increasing in both freshwater and marine ecosystems worldwide. However, few studies have examined how acidification will affect oxygen (O 2 ) transport...

...Alex R. Quijada-Rodriguez; Aaron G. Schultz; Jonathan M. Wilson; Yuhe He; Garett J. P. Allen; Greg G. Goss; Dirk Weihrauch ABSTRACT Freshwater organisms actively take up ions from their environment to counter diffusive ion losses due to inhabiting hypo-osmotic environments. The mechanisms behind...

... was to examine features necessary for survival in the same apparent habitat, because the two species co-exist in riffle areas of freshwater streams. Both species are highly sensitive to water loss as a result of high water loss rates and depend on immersion in fresh water (hypo-osmotic) to maintain water stores...

...Jason S. Bystriansky; Patricia M. Schulte SUMMARY Few studies have examined changes in salmon gill ion transporter expression during the transition from seawater to freshwater, a pivotal moment in the salmonid life cycle. Seawater-acclimated Atlantic salmon were transferred to freshwater and blood...

.... Four Na + /K + -ATPase α-isoforms were expressed in trout gills (α1a, α1b, α1c and α3). Na + /K + -ATPase α1c- and α3-isoforms were expressed at low levels in freshwater trout gills and their expression pattern did not change following transfer to 40% or 80% seawater. Na + /K + -ATPase α1a and α1b were...
