| dc.description | En Argentina existen escasos estudios sobre los epibiontes y los parásitos de crustáceos, siendo el objetivo del presente estudio reportar la presencia de los organismos asociados a anfípodos del género Hyalella y ampliar su distribución geográfica en ambientes de agua dulce de Patagonia. Los anfípodos se colectaron con un tamiz de 1 mm de tamaño de malla en diferentes cuerpos de agua dulce, abarcando un rango latitudinal entre los 38º27’S y los 54º55’S (provincias de Neuquén a Tierra del Fuego). Entre el año 2002 y el 2005 se capturaron un total de 24.571 anfípodos en 43 sitios y se registraron 21 taxones de epibiontes y de endoparásitos en Hyalella spp. Los epibiontes hallados fueron ciliados (Peritrichia sp. y Folliculinidae gen. sp.), digeneos (Catatropis chilinae, Notocotylus biomphalariae y otros notocotílidos no identificados a nivel específico) y rotíferos.
Los endoparásitos fueron microsporidios (Thelohania sp., Microsporidium sp. y Microsporidia sp.), digeneos (Maritrema patagonica), cestodes (4 especies de ciclofilídeos), nematodes (Acuariidae gen. sp., Hedruris suttonae y Hedruris sp.) y acantocéfalos (Acanthocephalus tumescens, Pomphorhynchus patagonicus, Pseudocorynosoma sp. y Polymorphus sp.). Los hallazgos realizados indican el importante rol que cumplen las especies de Hyallela en los ambientes acuáticos patagónicos considerando que son utilizados como sustrato por organismos epibiontes y como hospedadores intermediarios por diversos metazoos endoparásitos. | |
| dc.description | In Argentina studies about epibionts and parasites on crustaceans are scarce, so the objective of the present study was to report the presence of those organisms in amphipods of the genus Hyalella and to increase their distribution range in freshwater environments in Patagonia. Amphipods were collected with a sieve of 1 mm of mesh size in different freshwater environments in Patagonia, including a latitudinal range between 38º27’S and 54º55’S (Neuquen to Tierra del Fuego provinces). Between 2002 and 2005, 24.571 amphipods were captured in 43 localities. In the present study were recorded 21 taxons of epibionts and endoparasites in Hyalella spp. The epibionts were ciliates (Peritrichia sp. y Folliculinidae gen. sp.), digeneans (Catatropis chilinae, Notocotylus biomphalariae and another unidentified notocotilid) and rotifers. The endoparasites were microsporidians (Thelohania sp., Microsporidium sp. and Microsporidia sp.), digeneans (Maritrema patagonica), cestodes (4 species of Cyclophyllidea), nematodes (Acuariidae gen. sp., Hedruris suttonae and Hedruris sp.) and acanthocephalans (Acanthocephalus tumescens, Pomphorhynchus patagonicus, Pseudocorynosoma sp. and Polymorphus sp.). The findings reported in this study indicate the important role of Hyalella species in Patagonian freshwater environments considering they provide substrate for epibionts organisms and they act as intermediate hosts for many metazoans endoparasites. | |
