marine protected areas facilitate parasite populations among four fished host species of central chile.1. parasites comprise a substantial proportion of global biodiversity and exert important ecological influences on hosts, communities and ecosystems, but our knowledge of how parasite populations respond to human impacts is in its infancy. 2. here, we present the results of a natural experiment in which we used a system of highly successful marine protected areas and matched open-access areas in central chile to assess the influence of fishing-driven biodiversity loss on parasites of exploited f ...201323855822
optimal feeding strategy of the temperate herbivorous fish aplodactylus punctatus: the effects of food availability on digestive and reproductive patterns.in this study we examined differences in feeding behevior of populations of the marine temperate herbivorous fish aplodactylus punctatus, in three different localities off the chilean coast, which differ qualitatively and quantitatively in food availability. we test whether food selection follows optimal foraging strategics, whether there is any modification of the fishes' digestive tracts in relation to their diets, and whether differences in diet quality affect the allocation of energy into re ...199428313956
three species of plagioporine opecoelids (digenea), including a new genus and two new species, from marine fishes from off the coast of chile.villarrealina peruanus (syn. pirupalkia queulensis) is described from cilus gilberti, off the talcahuano region, chile. it is considered an opecoelid and is distinguishable by the combination of its extensive uterus, which reaches to the posterior extremity, and the vitellarium restricted to the hindbody. jerguillicola leonora n. g., n. sp. from aplodactylus punctatus, off the talcahuano region, chile, is distinguished by the uterus reaching into the post-testicular region, the lack of a seminal ...200211912348
