Aproximación a la dieta de Thalassoma lucasanum (familia Labridae) en el arrecife coralino de La Azufrada, isla Gorgona, Pacífico Oriental Tropical

El arcoíris de Cortés, Thalassoma lucasanum, es un pez arrecifal abundante en el Pacífico Oriental Tropical (POT). A diferencia de otras especies del género Thalassoma que son reconocidas por ser limpiadoras, en T. lucasanum este comportamiento es poco frecuente, ya que se alimenta principalmente de invertebrados mediante forrajeo. No obstante, la información sobre la ecología trófica de esta especie es limitada, especialmente en el POT. En este estudio se caracterizan los hábitos alimentarios de T. lucasanum en la isla Gorgona (POT) a partir del análisis de su contenido estomacal y se calcula su nicho trófico. Los moluscos fueron el principal recurso alimentario de T. lucasanum, siendo este el ítem de presa más importante y frecuente al ser encontrado en 100 % de los estómagos analizados (n = 5). En términos de biomasa, los crustáceos presentaron la mayor contribución a la dieta, con lo cual se posicionaron como el segundo ítem alimentario más importante. Otras presas incluyeron poliquetos, partes de peces y material calcáreo. Este estudio contribuye al conocimiento de la dinámica trófica de los ecosistemas arrecifales del POT.
