Resumen
La estructura trófica de los organismos es un aspecto importante en los ecosistemas ya que
describe cómo la energía se transmite entre distintos niveles tróficos, y permite comprender
como la interacción depredador-presa influye en la estructura de las comunidades. El hábitat
reúne las características abióticas y bióticas necesarias para la supervivencia de los
organismos, existiendo una relación directa entre complejidad del hábitat, la abundancia de la
fauna asociada y diversidad de especies y estrategias de forrajeo. Se caracteriza la dieta y
estructura trófica en 144 individuos, pertenecientes a 5 especies abundantes de la fauna íctica
submareal de la isla Robinson Crusoe.
The trophic structure of organisms is an important aspect of the ecosystem as it describes how energy is transferred between different trophic levels. The understanding of the trophic ecology of the species provides insight as predator-prey interactions and how this may influences the structure of the associated community. The habitat itself meets the abiotic and biotic characteristics necessary for the survival of organisms; there is a direct relationship between habitat complexity, abundance of organism and species and trophic diversity. Here, I characterized the diet and trophic structure in 144 individuals belonging to 5 species abundant fish fauna of the subtidal habitats at Robinson Crusoe Island
