Abstract: | Historical global respiration datasets of epipelagic copepods and recent bathymetric respiration datasets of mesopelagic, upper- and lower bathypelagic and abyssopelagic copepods were combined to build a global-bathymetric respiration model by adopting two regression models (theoretical and empirical ones). Designated independent variables including body mass (expressed as dry mass, carbon or nitrogen), habitat temperature, ambient oxygen saturation and the depth of occurrence were all significant, accounting 72-80% in the variation in these respiration data. Both theoretical and empirical regression models yielded similar results, but the latter was sensitive to the choice of body mass. The mechanisms for the negative effect of the depth of occurrence and the positive effect of ambient oxygen saturation on the respiration rates are discussed. |
