Genetic variation in a chilean endangered endemic: Gomortega keule (Molina) Baillon

Gomortega keule (Molina) Baillon is an endangered, rare species, the only representative of its genus, and endemic to Central Chile. Populations of this tree are now fragmented and few individuals can be found in any of them. Genetic diversity was studied in 33 individuals from three populations in Cauquenes, a coastal mountain area (35°58'S-72°41'W). Fifteen InterSimple Sequence Repeat primers were used to determine the degree of similarity between and within populations. This revealed that 30% of the variation exhibited was between populations while 70% was within; nevertheless individuals were clearly clustered in a pattern which reflected a narrow base of diversity. Three other species from the Laurales order were used in order to provide an external reference as to the degree of diversity. In addition, an external wild population from the native species, Peumus boldus, was used to verify the utility of the markers. We show that the primers are effective in quickly giving an estimate of the degree of diversity of a population, thus giving important topical information relevant to preserving endangered species. Aspects of the conservation and management policy for the species in order to maintain the remaining populations and to preserve the genetic resources are discussed.

Sangue e carne no cinema de Joaquim Pedro de Andrade

'Macunaíma' (Joaquim Pedro de Andrade, 1969) ends with a shot of blood emerging from the water. This text proposes an approach to this image following a comparison with other films by the same filmmaker: 'Couro de gato' (1960) and 'Os Inconfidentes' (1972). The main thesis is that in these images the aesthetical work with flesh synthesizes the ritual cannibalism and the capitalist one. This synthesis is specified in heroes’ assimilation by power.
