Respiration rates were estimated as oxygen consumption rates of the females of Neolovenula alluaudi (Copepoda, Calanoida). The oxygen consumption was measured at 15° and 25°C in egg-carrying and non-egg-carrying females. The experiments carried out at 15°C showed that the oxygen consumption rates (OC; nmol O2 ind-1 h-1) were higher in females carrying an egg sac than in those that did not. When specific oxygen consumption rates (SOC; nmol O2 μg-1 h-1) were calculated, females with egg sacs consumed less oxygen than those without egg sacs, but this was not statistically different. At 25°C, non-carrying females increased their SOC rates significantly, while the females carrying an egg sac exhibited values of SOC rates similar to those at 15°C. The specific oxygen consumption rates of the egg sac were also calculated at both temperatures, showing that the egg sac consumed less oxygen at 25°C than at 15°C. These results explain in part the lower SOC values shown by the carrying females at 25°C.

Les taux de respiration ont été estimés comme taux de consommation d'oxygène des femelles de Neolovenula alluaudi (Copepoda, Calanoida). La consommation d'oxygène a été mesurée à 15° et 25°C chez des femelles ovigères et non-ovigères. Les expérimentations menées à 15°C ont montré que les taux de consommation d'oxygène (OC; nmol O2 ind-1 h-1) étaient supérieurs chez les femelles portant un sac ovigère par rapport à celles qui n'ent portaient pas. Quand les taux de consommation d'oxygène spécifiques (SOC; nmol O2 μg-1 h-1) ont été calculés, les femelles avec sac ovigère consommaient moins d'oxygène que celles sans sac ovigère, mais ce résultat n'était pas statistiquement significatif. A 25°C, les femelles sans oeufs présentaient un taux de SOC significativement plus élevé, tandis que les femelles portant un sac ovigère montraient des valeurs de leur taux de SOC identiques à ceux de 15°C. Les taux spécifiques de consommation d'oxygène du sac ovigère ont été également calculés aux deux températures, et ont montré que le sac ovigère consommait moins d'oxygène à 25°C qu'à 15°C. Ces résultats expliquent en partie les valeurs de SOC inférieures chez les femelles ovigères à 25°C.
