Norwegian Polar Institute seminar: “Pan Arctic effects of ocean acidification in pelagic copepods”, 9 March 2016

Date & time: 9 March 2016, 1:00 PM – 1:30 PM
Venue: Norwegian Polar Institute, Fram Centre, 4th floor, rooms 5010-12 «Tre kroner»

Animals’ ability to counter effects of ocean acidification will be enhanced by any present day adaptations to local environments in different geographic regions. Such differences in local adaptation may enable complementation when affected populations are re-populated from neighbouring populations. As part of the Ocean Acidification Fram Flagship we compared effects of decreasing pH on prey ingestion rate and metabolic rate among three geographically isolated populations of the pelagic copepod Calanus glacialis. While, populations from Kongsfjorden and Billefjorden were severely affected by decreasing pH, a population from Disko Bay (Davis Strait) remained unaffected. Thus, repopulation by Davis Strait C. glacialis could alleviate potential severe effects of OA in the Svalbard area.
