WaterGlacial-origin lakes in southern South America are increasingly exposed to anthropogenic pressures, but early signs of contamination often remain undetected in apparently pristine systems. In this study, we assessed the bioaccumulation of trace metals (Cu, Mn, Zn, Cr) in the tissues of the native freshwater mussel Diplodon chilensis and their ...

El bivalvo de agua dulce Diplodon chilensis como herramienta para el estudio de ambientes acuáticos contaminados en Patagonia Norte. [PDF]
, 2014 El incremento en el vertido de efluentes cloacales hacia los cuerpos de agua, como producto de la expansión de las áreas urbanas, representa una amenaza tanto a nivel ecosistémico como sanitario.

Native mussels, Diplodon chilensis, were sampled from four lakes in Nahuel Huapi National Park, Northern Patagonia, Argentina in order to evaluate heavy-metal distribution in the region and to assess the contribution of this compartment of the trophic web to their circulation in the food chain.

Summary Spermiogenesis and sperm ultrastructure of Diplodon chilensis chilensis have been studied. Early spermatids show some peculiar characteristics which include scanty cytoplasm mitochondria restricted to a juxtanuclear region and a poorly developed Golgi complex, a feature present throughout spermiogenesis.

The freshwater mussel Diplodon chilensis (Hyriidae) is abundant in bays where salmon farming takes place in southern Chilean lakes. In order to evaluate the possibility of mitigating salmon farming impacts through the management of benthic communities, we measured the ability of D.
