Abstract:
In this research we studied the diet of Enteroctopus megalocyathus from three principal locations of the octopus fishery (Ancud, Quellón and Melinka) in southern Chile. The gastric contents of 523 individuals, collected between October 1999 and September 2000, were examined and statistically analysed. Diet composition was described using detrended correspondence analysis and analysed as a function of predator gender, body size and fishing area. Food items were found in ~50% of the octopuses examined and a total of 14 prey items were recognized. The diet of E. megalocyathus consisted primarily

A new species is described, Hemilamprops chilensis, from Chile. The new species was collected at several localities, from Bahia Herradura in the central part of the country, to Ancud on the island of Chiloe in the south. The depth of collection ranged from 0–30 m. The species with the closest affinity to H. chilensis is the South African species, H. glabrus Day, 1978. The new species is distinguished from all other Hemilamprops by the combination of a short lateral ridge anteriorly on the carapace, maxilliped 3 with the basis much longer than the remainder of the appendage, and the telson bear

Abstract:
The temperate rainforests of southern Chile, a recognized biodiversity hotspot, were significantly affected by Pleistocene glacial cycles in their southern portion and have been severely disrupted mainly due to recent human activities. Additionally, the landscape is characterized by a series of potential barriers to gene flow, such as the Chacao Channel, Cordillera de Piuche in Chiloé and both the Ancud and the Corcovado gulfs. We used mitochondrial DNA sequences and microsatellite data across several populations to evaluate the genetic variability and structure of the sigmodontine rodentAbrot
