Galaxias platei, es un pez endémico de Chile y cubre una extensa área geográfica desde la zona centro-sur hasta gran parte de la Patagonia (38ºS-54ºS), incluyendo también parte de Argentina. En este trabajo se determinó el contenido somático de ADN nuclear (valor 2C) de Galaxias platei (Galaxiida...
This study reports the present distribution range of Musculium argentinum (D'Orbigny, 1835) and Musculium patagonicum Pilsbry, 1911 in Chile, from sampling data carried out from 2002 to 2006. Morphological and biometric characteristies of the studied populations show that M. argentinum is discont...

The gonadal organization and cytological characteristics of gametogenesis in a population of the freshwater clam Musculium argentinum (d'Orbigny, 1835) are described. Sections of the rather small gonad demonstrate the existence of hermaphroditic specimens, and is composed of hermaphrodite follicl...

El número cromosómico y la morfología del cariotipo de Girella laevifrons (Tschudi 1846) son descritos por primera vez. G. laevifrons presenta un número cromosómico 2n = 48 y su cariotipo está constituido por 24 pares de cromosomas acrocéntricos en ambos sexos, similar a lo documentado previament...
The karyotype of Luzuriaga radicans R. & P. was quantitatively studied, assessing characters such as chromosome morphology and size, satellite location, asymmetry level and bimodality. L. radicans has an asymmetric and bimodal karyotype 2n = 20 with three metacentric pairs, followed by six submet...
