Morphology, anatomy and histology of Doto uva Marcus, 1955 (Opisthobranchia: Nudibranchia) from the Chilean coast Naturalis
Fischer, M.A.; Velde, G. van der; Roubos, E.W..
Doto uva Marcus, 1955 is a nudibranch species recorded from the Brazilian and Chilean coast. In spite of its wide distribution, D. uva has been described only superficially, mainly as to the pattern of its coloration, external morphology, radular teeth and reproductive system. Here we substantially extend this description, paying special attention to the morphology, anatomy and histology of the digestive and reproductive system. Furthermore, new data on the morphology of the central nervous system and its cell types are given, and finally, the egg mass is described. On the basis of these data, we consider the Doto specimens described from Chile conspecific with those from Brazil.

The onshore distribution and abundance of the South American sea lion Otaria flavescens along the central Chilean coast was estimated during the period January-February 2007. Additionally, changes in population abundance during the period 1970-2007 were examined. Population surveys were based on photographs taken from boats or aircraft. A total of 16301 sea lions (CI = 16209-16375) were counted in 33 colonies (6 breeding and 27 non-breeding sites). After correction to account for the proportion of individuals at sea and for pups not seen at the time of the survey, the mean estimated abundance was 18179 (95 % CI = 17777-18851) sea lions. Population trend analysis showed that from 1970 to 1985, South American sea lions showed a positive increase of...

Family Pilargidae (Polychaeta): new distributional ranges and a new record for the Chilean coast RChHN
ROZBACZYLO,NICOLAS; QUIROGA,EDUARDO.
Species of the family Pilargidae are revised based on bibliographic information and on specimens collected in soft bottoms, from 16 to 68 m depth, in three localities of the northern Chilean coast. Five genera and six especies, including a new record for the Chilean fauna, Parandalia fauveli, are recognized. Synonyms, diagnostic features, geographic distribution data and illustrations are provided for each species. Abundance data and biomass, as well as granulometry and organic matter of the sediments where the specimens were collected, are also reported. Presence of Pilargis berkeleyae and Sigambra bassi in the collected material allows extension of their distributional ranges from approximately 35-36ºS to 18º30'S. A taxonomic key to the six species of...

Algal wrack deposits and macroinfaunal arthropods on sandy beaches of the Chilean coast RChHN
JARAMILLO,EDUARDO; HUZ,ROSARIO DE LA; DUARTE,CRISTIAN; CONTRERAS,HERALDO.
Four Chilean sandy beaches were sampled during the summer of 2000, to study the role of stranded algal wrack deposits on the population abundances of three detritus feeder species of the macroinfauna that inhabit the upper shore levels of that beaches: the talitrid amphipod Orchestoidea tuberculata Nicolet, the tylid isopod Tylos spinulosus Dana and the tenebrionid insect Phalerisida maculata Kulzer. The beaches were Apolillado (ca. 29° S), Quidico (ca. 38° S), Guabún and Mar Brava (ca. 42° S). Replicated samples were collected with a plastic cylinder (25 cm in diameter) from algal wrack deposits including the sediments beneath the wrack and nearby bare sand areas. Samples were collected at two beach levels, one closer to the sea with fresh deposits and...
