Variaciones espacio temporales de la estructura comunitaria de endoparasitos en peces intermareales de Chile central: descriptores parasitologicos, composicion de especies y anidamiento

The parasite community structure in fish species of Chile have scarcely been analysed through time and locations, making it difficult to understand the spatio-temporal variation patterns. In this study, we investigated whether the endoparasitic community of three intertidal fishes in central Chile exhibited spatial or temporal changes. We collected a total of 954 individuals of Helcogrammoides chilensis, Gobiesox marmoratus and Scartichthys viridis in the intertidal rocky zone in localities close to the bays of Valparaíso (~32o45’S, 33o30’S) and of Concepción (~36o28’S, 36o41’S), during in 2013 and 2014. We analized the endoparasite community for each host according to their numerical descriptors, species composition and nestedness, comparing these communities as a function of both space and time. The average richness, abundance and diversity of the parasite infracommunity did not exhibit significant difference between localities (Valparaíso vs Concepción) for any of the host species. Only the parasitological descriptors of H. chilensis and G. marmoratus showed significant difference between years for Valparaíso. Similarity of parasite composition of each host species was low between years and geographical localities. The endoparasite infracommunity of S. viridis exhibited a nestedness
