Abstract
The ctenophore Mnemiopsis leidyi is an ecologically important predator in temperate coastal environments. Their populations fluctuate seasonally, serving as sinks of nutrients during periodic blooms, but as sources via excretion and during population collapse. Ctenophores were analyzed for elemental composition (C, N, and P) during 2008 and 2009 in Great South Bay, NY, USA. Salt-free weight percent C, N, and P correlated positively with ctenophore sizes and zooplankton prey abundances. Nitrogen and P were higher at the onset of blooms than during collapse when prey were substantially fewer. Ctenophores collected during average to high zooplankton densities had atomic ratios averaging C/N ~6:1 and C/P ~66:1, but became C- and P-depleted (C/N ~5:1, C/P ~128:1) with decreasing zooplankton. Incubations demonstrated rapid remineralization of ctenophore biomass (as NH4 +, HPO4 2−), following first order kinetics (e.g., k ~0.1–0.4 day−1) with enriched stoichiometric N and P fractionation relative to biomass under both oxic and anoxic conditions. Based on reported excretion rates, nutrient regeneration from excretion by active populations greatly exceeds nutrients remineralized during population crashes. To our knowledge, this is the first study documenting natural seasonal patterns in ctenophore elemental stoichiometry as a function of ctenophore size and prey availability.
