Understanding the minimum energetic expenditure for a species across its life stages has practical value in predicting how species may respond to changing habitat conditions. Using a static respirometry, I measured the thermal sensitivity (Q10) and metabolic allometry of the round stingray, Urobatis halleri, based on their standard metabolic rate (SMR). A total of 33 individuals (mass range=0.03 - 0.86 kg) were acclimated for > 14 days at three temperature treatments (15°, 23°, 27°C) spanning the seasonal water temperature variation in Southern California. An average thermal sensitivity (Q10) of 3.2 was estimated for the round stingray across the range of experimental temperatures. The juvenile size class showed a higher Q10 coefficient (Q10=4.3) when compared to the adults (Q10=3.0). There was a negative relationship between this species mass-specific scaling exponent (b) and temperature treatment (b=0.99 at 15°C, b=0.86 at 23°C, and b=0.79 at 27°C). Metabolic Q10 estimations showed that the round stingray is relatively sensitive to the thermal fluctuations they experience in southern California. While a relatively high Q10 may allow this species the ability to optimize their daily net energy gain by exploiting the local thermal heterogeneity, a higher thermal sensitivity in juveniles could have adverse effects on the population fitness under a pervasive increase of ocean's temperature. Because of the scaling exponent can be affected by temperature, modeling studies should consider correcting for this effect when using scaling relationships as an input for more precise bioenergetic models.

520 $a Conocer la minima demanda energetica de las especies a lo largo de sus estadios de vida tiene un valor practico en la prediccion de como estas responderan a cambios en las condiciones ambientales. Con el uso de respirometria estatica, se midio la sensibilidad termica (Q10) y el exponente de escalimiento (b) de la raya redonda, Urobatis halleri, basado en su metabolismo estandar (SMR). Un total de 33 individuos (0.03 - 0.86 kg) fueron aclimatados for > 14 dias a tres temperaturas de tratamiento que reflejan la variacion termica estacional de la costa del sur de California. Resultados mostraron un valor Q10 promedio de 3.2 para la raya redonda a traves de las temperaturas de tratamiento. Individuos juveniles mostraron en coeficiente Q10 (Q10=4.3) mayor que el de los adultos (Q10=3.0). Estimaciones del exponente de escalamiento de esta especie mostraron una relacion inversa con la temperatura de tratamiento (b =0.99 a 15°C, b =0.86 a 23°C, and b =0.79 a 27°C). Este estudio muestra que la raya redonda es relativamente sensible a las fluctuaciones termicas que experimental en el sur de California. Si bien el alto Q10 de esta especie podria permiterle optimizar su ganancia energetica mediante la explotacion de la heterogeneidad ambiental, un continuo incremento en la temperatura del mar podria tener efectos adversos para el fitness de esta poblacion. Debido a que el exponente de escalamiento de la raya redonda puede ser afectado por la temperatura, futuros estudios de modelamiento podrian usar los resultados de este estudio en la generacion de modelos bioenergeticos de mayor precision.
