I attached the Llorens-Mares paper to remind us that we have a large euxenic population in the deep water of Fryxell with an “ecotone” at the oxycline. Recent experiments that I have done show high rates of methane oxidation at the oxyclines in FRX, WLB and ELB. These ecotones are relatively stable, but any major mixing events will disrupt them. We could try a few transplant experiments in dialysis bags to see how function and diversity change when the oxycline populations are displaced.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>JP<o:p></o:p></p></div></body></html>
