• Cadmium and calcium transport along the gastro-intestinal tract of rainbow trout : more than “gut feelings” on mechanisms of uptake 

  Klinck, Joel S. (Biology Department, McMaster University, Hamilton, ON, CA, 2011-10)

  Teleosts take up metals by two major pathways: gills and/or gut. Past research is heavily focused on branchial uptake despite evidence that the gastro-intestinal tract (GIT) is the dominant route in some natural environments. ...
• Waterborne copper exposure inhibits ammonia excretion and branchial carbonic anhydrase activity in euryhaline guppies acclimated to both fresh water and sea water 

  Zimmer, Alex; Indianara Fernanda Barcarolli; Chris M. Wood; Adalto Bianchini (Elsevier, 2012)

  Inhibition of ammonia excretion (J(amm)) is a common response to Cu exposure in freshwater (FW) and seawater (SW) organisms. To determine the mechanism of this response, a euryhaline species of guppy (Poecilia vivipara) ...
