Ionic regulation in the common copepod Eurytemora affinis

Kelsey Johnson worked in the laboratory of Guy Charmantier at the Université de Montpellier, Franc,  to study osmoregulatory structures that are involved in ionic regulation in the common copepod Eurytemora affinis.

Carol Lee writes:

During the summer of 2011, an undergraduate student from my laboratory, Kelsey Johnson, worked in the laboratory of Guy Charmantier at the Université de Montpellier, France to perform collaborative research.  The goal of this study was to characterize osmoregulatory structures that are involved in ionic regulation.  She was able to localize the ion-motive ATPase enzymes that evolve in activity and expression during invasions by the common copepod Eurytemora affinis.  She characterized the organs involved in ionic regulation and named novel structures that had not been previously characterized.  Her results will allow us to discover exactly how the functions of these structures are altered during saline to freshwater invasions.
