Última Influence of biotic and abiotic factors on the metazoan parasite communities of a native prey fish: study in 28 Andean Patagonian lakes Ecología austral Fernandez,Valeria; Garibotti,Gilda; Semenas,Liliana; Viozzi,Gustavo. Galaxias maculatus (small puyen) is a prey fish which plays a main role in lake food webs of Patagonia. Previous studies, at local scale, have shown that the richness and composition of parasitic metazoan component communities associated to G. maculatus in a group of small shallow lakes in the surroundings of the Nahuel Huapi Lake, are affected by the composition of the native fish assemblage in each lake. The aims of this work were: a) to characterize the helminth community of G. maculatus at regional scale, including data of 28 Andean lakes of the Neuquén and Río Negro Provinces, and b) to identify biotic and abiotic factors of these lakes influencing the occurrence and prevalence of the different helminth species parasitizing this highly abundant and...

Ano: 2015 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1667-782X2015000300007 The cephalic lateral line system of temperate perches (Perciformes: Percichthyidae) from Argentinean Patagonia Rev. Bras. Zool. Vega,Rocío M.; Viozzi,Gustavo P.. ABSTRACT The species of Percichthys (Percichthyidae) are endemic to southern South America. Some authors have pointed out that the genus includes four valid species, based on the morphology of the head, jaws, and fins. A phylogenetic analysis published by other authors suggests that three of them are morphotypes belonging to the same species, Percichthys trucha (Valenciennes, 1833). The aim of this study is to describe for the first time the morphology of the cephalic seismosensory system of Patagonian perches, and how these characters vary in the three morphotypes, in order to provide morphological elements to analyze the taxonomy of these fish species. Comparisons of the cephalic seismosensory system between juveniles and adults were also conducted....
