Synthesis towards a global-bathymetric model of metabolism and chemical composition of mysid crustaceans

摘要: Abstract Respiration and ammonia excretion data chemical composition [water content, ash, carbon (C), nitrogen (N) C:N ratios] of 13–32 mysids from freshwater, coastal littoral, epipelagic abyssopelagic zones the world's oceans were compiled. The independent variables including body mass, habitat temperature sampling depth all significant predictors respiration, accounting for 74–85% variance in data, while mass excretion, 85–86% variance. Atomic O:N ratios (respiration: excretion) ranged 7.9 to 44.8 (median: 18.7), indicating protein-oriented metabolism. Body water content ash not correlated with depth, but C N increased decreased, respectively, increase depth. As judged by ratios, protein was considered be major organic component most mysids. However, some deep-sea exhibited high (8.6–10.6), suggesting a predominance lipids body.
