Abstract: knowledge on what, how much, when and where hosts eat and live should help to understand the changes that occur in parasite communities because transmission of endoparasites is tightly linked to diet composition as well as ectoparasites are to the use that hosts make of the habitat. thus, geographical and ontogenetic variations in diet and parasite fauna of the thornfish bovichthys chilensis are described, and discussed taking into account the ontogenetic shifts in this host's niche. a total 122 individuals: 108 juveniles collected from the intertidal zone at four localities along the south-central coast of chile (between 33o and 40o s), and 14 adults collected from the shallow subtidal at a fifth locality (36o s), were examined for food contents and parasite infracommunities. food items were encountered in almost 70 % of fish examined with 25 prey items being recognized. only one of the prey items was found in both juvenile and adult fish. the diet of juvenile fish consisted mainly of amphipods and while that of adults was mainly composed of crustacean decapods. almost 40 % of fish examined harbored parasites with a total of 624 individuals and belonging to 16 taxa being identified, four of which were shared between juvenile and adult fish. prevalence, total intensity, richness, and diversity of parasites was similarly low among juvenile fish sampled at four different localities, while significant differences in total prevalence, dietary and parasite infracommunity composition among localities were found. absence of a clear relationship among juvenile fish between the composition of the diet and of infracommunities may be due to the fact that parasitoses are necessarily recent. adult hosts had infracommunities with greater total prevalence, total intensity, taxonomic richness and diversity than juveniles sampled at a nearby locality. all these observations could be associated to ontogenetic shifts in diet and concomitant shifts in parasite fauna. further studies ar

Resin Diterpenes from Austrocedrus chilensis  [PDF]
Verónica Rachel Olate,Olatz Goikoetxeaundia Usandizaga,Guillermo Schmeda-Hirschmann
Molecules , 2011, DOI: 10.3390/molecules161210653
Abstract: Seventeen diterpenes belonging to the labdane, abietane and isopimarane skeleton classes were isolated from the resin of the Chilean gymnosperm Austrocedrus chilensis and identified by spectroscopic and spectrometric methods. The diterpene 12-oxo-labda-8(17),13E-dien-19 oic acid is reported for the first time as a natural product and 14 diterpenes are reported for the first time for the species.
A TEORIA DOS DIREITOS ANIMAIS HUMANOS E N O-HUMANOS, DE TOM REGAN
Gabriela Dias de Oliveira
Ethic@ : an International Journal for Moral Philosophy , 2004,
Abstract: What place should non-human animals have in an acceptable moral system? Regan s rights view points out to coherence as expression of a rational demand and grounds moral rights of human and non-human animals on the principle of equality. What all human beings and some animals (especially mammals) have in common is the property of being a subject-of-alife, i. e., of being sensitive self-conscious individuals. From this property Regan requests the equal inherent value of all subjects-of-a-life; such value will be converted into a right of be respected (we cannot use them merely as a means to our ends). Animals still exist on the borderline of our moral concepts. Given these considerations, Regan concludes that we must radically alter the ways in which we treat animals.
Sulfated Polyhydroxysteroids from the Antartic Ophiuroid Gorgonocephalus Chilensis  [PDF]

Molecules , 2000, DOI: 10.3390/50300348
Abstract: Five disulfated steroids and a mixture of monosulfated steroids were isolated from the ethanolic extract of the antarctic ophiuroid Gorgonocephalus chilensis. The structures were determined by 1H-NMR, 13C-NMR and FABMS.

Abstract: samples of pinguicula chilensis (lentibulariaceae) where collected from the cordillera de nahuelbuta in order to characterized some of its anatomical features. leaves where processed for scanning electrom microscopy analysis in which pedunculated trichomes and secrecetory glands form 4-8 cells could be observed

Abstract: introduction: phenolic compounds are well-known antioxidants and their regular ingestion contribute to improve antioxidant status of plasma. phytochemical findings describe phenolic compounds in aristotelia chilensis (molina) stuntz leaves, therefore, their administration in herbal teas may support the prevention of diseases whose etiology lies in the oxidative stress. objetive: to evaluate the antioxidant capacity of the herbal tea and the extracts from dry aristotelia chilensis (molina) stuntz leaves. methods: the leaves underwent a phenolic extraction process with successive solvents, and the stabilizing capacity of radical 2,2′- azino-di-(3-etilbenzotiazolin-6-sulfonatodiamonio) and hydroxyl both from extracts and 1 % tea was evaluated. also the antioxidant capacity of plasma before and after taking the tea was evaluated according to the etnomedical use. results: the extracts obtained with polar solvents showed the stabilizing capacity of free radicals and the antioxidant capacity of plasma which, after taking a. chilensis tea, increased to 30.27% as an average. conclusion: herbal tea and extracts from a. chilensis exhibited antioxidant capacity under the described conditions.
