A desintegração da plataforma de gelo da enseada Larsen A, em 1995, possibilitou uma oportunidade para estudar a comunidade bêntica da região. Foram analisadas a densidade da macrofauna e a densidade e biomassa da meiofauna. Duas estações na região de mar aberto, no Mar de Weddell, também foram coletadas, para comparações entre diferentes ambientes. Parâmetros ambientais também foram analisados, e serviram para tentar explicar a variação da fauna bêntica. Na região do Mar de Weddell as porcentagens de matéria orgânica foram maiores que na enseada Larsen A, provavelmente um reflexo da maior produtividade primária da área, enquanto as porcentagens de carbonato foram mais altas na enseada do que em mar aberto. A granulometria variou entre silte arenoso a areia síltica, sendo as estações no Mar de Weddell tiveram maiores porcentagens de areia. Em relação à fauna, Nematoda foi o táxon mais abundante, seguido por Copepoda e Nauplii dentro da meiofauna, enquanto Bivalvia e Polychaeta foram os mais abundantes dentro da macrofauna. As maiores densidades de meio- e macrofauna foram encontradas nas estações de mar aberto, e apresentaram correlação com as concentrações de pigmentos. A biomassa total dos nemátodes se correlacionou à biomassa individual do grupo, enquanto a biomassa dos copépodes se correlacionou com a densidade do grupo. Através dos resultados obtidos no presente trabalho foi possível observar que as comunidades bênticas das duas regiões estudadas diferem entre si, em termos de densidade e número de grandes grupos encontrados. E que a disponibilidade de alimento é o principal fator estruturados da fauna na região. / The collapse of the Larsen A ice shelf, in 1995, allowed an opportunity to study the benthic community in the region. The density of macrofauna and the density and biomass of meiofauna were analyzed. Two open water stations in the Weddell Sea were also collected for comparisons between different environments. Environmental parameters were analyzed to look for possible relations with benthic fauna distribution, abundance and biomass. In the Weddell Sea region the percentage of organic matter were higher than in the Larsen A, which was probably a reflection of the higher primary productivity of the area, while the carbonate percentages were higher in the bay than in open water. Particle size ranged from sandy silt to siltic sand, with Weddell Sea stations presenting higher sand content. Nematoda was the most abundant meiofauna taxon, followed by copepods and Nauplii, while Bivalvia and Polychaeta were the most abundant macrofauna. The highest densities of meio- and macrofauna were found in the open sea stations, and were correlated with pigment concentrations. The total nematode biomass was correlated with nematode individual biomass of the group, while copepod biomass correlated with its density. We observed that the benthic communities differed between studied areas in terms of density and taxon richness. Food availability appears to be the main factor structuring fauna in the region.

<p>The aim of the study is to investigate how double-consciousness operates through contrastive color imagery in Nella Larsen’s novel Quicksand. A focal point of the analysis is to show how Larsen thematizes the ability to benefit from bright colors and how color choice determines the quality and level of freedom in life.</p><p>Together with W. E. B. Du Bois’s theory of double-consciousness, a few other literary works by writers of the Harlem Renaissance have been considered in order to further support my arguments. I link these other writers’ perspectives to Quicksand and to the novel’s theme of color as a path to freedom.</p><p>In Quicksand, a broader path of colors, more bright than dull, leads to freedom, as is made evident through the novel’s connection of bright colors with Harlem’s freedom of expression. Furthermore, a narrow path of colors is contrastively figured as the course towards tragedy, which is clearly seen in the novel through the example of the protagonist Helga’s “sinking” due to an absence of color.</p>
