Influence of temperature, habitat and body mass on routine metabolic rates of Subantarctic teleosts

description |
Subantarctic notothenioids are exposed to wider variations in temperature than those encountered in the Antarctic Ocean, the ancestral environment of the group. In this study the influence of temperature on the routine metabolic rate of Subantarctic teleosts was described and the results were compared with routine metabolic rates of species with different geographical distributions, exploring the concept of Metabolic Cold Adaptation (MCA). Oxygen consumption (VO2R) was determined as an estimate of the routine metabolic rate for the following Subantarctic notothenioids: Paranotothenia magellanica, Patagonotothen sima, Eleginops maclovinus, Harpagifer bispinis and the eelpout Austrolycus depressiceps. In all studied species and tested temperatures, body mass and VO2R showed a positive correlation. A drop in the temperature from 10 to 2°C produced a significant reduction of VO2R values with a Q10 (10-2) varying between 4.69 and 9.54. VO2R values were related to species habitat: pelagic species reached the highest values of VO2R, while sluggish species had the lowest ones. We can conclude that the metabolic rates of these species of Subantarctic fish do not show MCA at the investigated temperatures. Los nototénidos subantárticos se encuentran expuestos a mayores variaciones de temperatura que las del Océano Antártico, el ambiente ancestral del grupo. En este estudio, se describe la influencia de la temperatura en la tasa metabólica de rutina de teleósteos subantárticos. Los resultados fueron comparados con tasas metabólicas de rutina de especies con diferente distribución geográfica, explorando el concepto de Adaptación Metabólica al Frío (AMF). Se determinó el consumo de oxígeno (VO2R) como una estimación de la tasa metabólica de rutina para las siguientes especies de nototénidos subantárticos: Paranotothenia magellanica, Patagonotothen sima, Eleginops maclovinus, Harpagifer bispinis y el Zoarcidae Austrolycus depressiceps. La masa del cuerpo y la VO2R mostraron una correlación positiva en todas las especies estudiadas y temperaturas experimentales. Una disminución de la temperatura de 10 a 2°C produjo una reducción significativa de los valores de VO 2R, con un Q 10 (10-2)que varió entre 4,69 y 9,54. Los valores de VO 2R estuvieron correlacionados con el hábitat particular de cada especie. Las especies pelágicas alcanzaron los valores más altos, mientras que las especies poco activas tuvieron los más bajos. Podemos concluir que la tasa metabólica de estos peces subantárticos no presenta AMF a las temperaturas ensayadas. |
