Spatio-temporal variations in the diet and stable isotope composition of the Argentine hake Merluccius hubbsi Marini, 1933 of the continental shelf of southeastern Brazil

The feeding ecology of Merluccius hubbsi was investigated in 2 regions of SE Brazil. The major food sources for the hakes were fish, crustaceans, and squid. In the upwelling system of Cabo Frio, the diet was very similar in the summers of 2001/2002 and spring 2002; fish were the most important prey followed by crustaceans. In Ubatuba, euphausiids were an important prey during the winter 2001 (100 m), while in the summer 2002, fish and amphipods predominated in the diet in the shallower site (40 m) and squid in the deeper site (100 m). The hakes showed temporal differences in stable isotope signatures in both regions, while C:N ratios varied only in Cabo Frio. delta(15)N and delta(13)C (bulk and corrected for lipid content) increased with fish length, which seems to be related to the increasing importance of fish and decreasing importance of euphausiids and amphipods in the diet of larger hakes. The mean trophic level of 3.7 for M. hubbsi was estimated using delta(15)N of bivalves as baseline and the fractionation of 3.4aEuro degrees between trophic levels.

O olho mágico, o abrigo e a ameaça: convulções - Ruy Guerra filma Chico Buarque

Desde a década de 1990, o «cinema da retomada» focaliza a violência social, a corrupção e a crise institucional no Brasil. São poucos os filmes que se afastam desta postura de transparência e de ajuste aos códigos dominantes no mercado, trabalhando dentro de um estilo afinado ao cinema moderno de autor. Um dos melhores exemplos nesta direção é Estorvo (2000), de Ruy Guerra, adaptação do livro de Chico Buarque. O artigo demonstrará como o filme, tal qual a obra original, opta por uma narrativa que nos desconcerta ao trabalhar na própria forma a crise do sujeito na atualidade, repondo nossa interrogação sobre o percurso das personagens – e da ordem familiar – em seu peculiar envolvimento com aspectos contundentes da violência social no Brasil.
