Stuart Hall, cultural studies e a nostalgia da dominação hegemônica

Stuart Hall é um dos poucos autores contemporâneos que ainda se apóia no conceito de ideologia. Ela interfere na língua falada definindo limites, regulando a forma discursiva com a intenção de estabilizá-la e congelá-la. Ela domina o bloco histórico e a estratégia seria a de unir as camadas populares, a partir de dentro, para que estas possam fortificar-se e combatê-la. Mas todo esse esquema tem sabor nostálgico, como se houvesse uma manobra dos poderosos e os dominados não se identificassem com os signos de poder e prestígio. Como no caso da “leitura crítica”, não seria o caso de modernizar Stuart Hall?

Range extensions along western Atlantic for Epialtidae crabs (Brachyura, Majoidea) genera Acanthonyx Latreille, 1828 and Epialtus H. Milne Edwards, 1834

The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. Milne Edwards, 1834, and E. brasiliensis Dana, 1852. Specimens of both genera from different carcinological collections were studied by comparing morphological characters. We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil), and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil), and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens.

Comportamiento de "Osilinus atratus" (Wood, 1828) ante diferentes sustratos rocosos

[ES] Se estudia el comportamiento del burgado (Osilinus atratus) ante diferentes tipos de sustratos rocosos, tanto en color como en tamaño. Los individuos muestran cierta tendencia a permanecer sobre sustratos de color gris-verdoso, sobre piedras de basalto-fonolitas, muy similares a los colores que abundan en las conchas de esta especie. Igualmente, evitan permanecer sobre sedimentos de pequeña granulometría, incrementándose el tiempo de permanencia cuanto mayor es el grano del sedimento.

A VEGETATION RECONSTRUCTION OF UNION COUNTY, PENNSYLVANIA DURING THE EARLY HISTORICAL PERIOD (1755-1855)

This thesis assesses relationships between vegetation and topography and the impact of human tree-cutting on the vegetation of Union County during the early historical era (1755-1855). I use early warrant maps and forestry maps from the Pennsylvania historical archives and a warrantee map from the Union County courthouse depicting the distribution of witness trees and non-tree surveyed markers (posts and stones) in early European settlement land surveys to reconstruct the vegetation and compare vegetation by broad scale (mountains and valleys) and local scale (topographic classes with mountains and valleys) topography. I calculated marker density based on 2 km x 2 km grid cells to assess tree-cutting impacts. Valleys were mostly forests dominated by white oak (Quercus alba) with abundant hickory (Carya spp.), pine (Pinus spp.), and black oak (Quercus velutina), while pine dominated what were mostly pine-oak forests in the mountains. Within the valleys, pine was strongly associated with hilltops, eastern hemlock (Tsuga canadensis) was abundant on north slopes, hickory was associated with south slopes, and riparian zones had high frequencies of ash (Fraxinus spp.) and hickory. In the mountains, white oak was infrequent on south slopes, chestnut (Castanea dentata) was more abundant on south slopes and ridgetops than north slopes and mountain coves, and white oak and maple (Acer spp.) were common in riparian zones. Marker density analysis suggests that trees were still common over most of the landscape by 1855. The findings suggest there were large differences in vegetation between valleys and mountains due in part to differences in elevation, and vegetation differed more by topographic classes in the valleys than in the mountains. Possible areas of tree-cutting were evenly distributed by topographic classes, suggesting Europeans settlers were clearing land and harvesting timber in most areas of Union County.
