Quaternary of the Pantanal, west-central Brazil

The Pantanal is a tectonic depression located at the left margin of the Upper Paraguay River. The Paraguay is the trunk river of an alluvial depositional tract composed by several large marginal alluvial fans, the Taquari fan being the largest one. The present landscape is a complex tropical wetland characterized by month-long floods every year, with geomorphic features derived from the present conditions and others inherited from successive Pleistocene and Holocene climates. Some areas containing ponds are landscape relicts generated by eolian deflation during the Last Glacial Maximum. Many ponds, closed depressions isolated from the superficial waters by vegetated crescent ridges of fine sands, were interpreted as salt pans bordered by lunette sand dunes. Initiation of the modern wetland has occurred during the Pleistocene/Holocene transition, with the change to a more humid climate and the individualization of lacustrine systems. Active tectonics has been playing an important role in the development of the Pantanal landscape. Nowadays, the Paraguay River meanders in a large flood plain with extensive swamp surfaces, being structurally constrained by faults in the west border of the basin. Sedimentation within the Pantanal wetland is also affected by tectonic activity, especially along faults associated with the Transbrasiliano Lineament. (C) 2003 Elsevier B.V. Ltd and INQUA.

The Phylogeographic History of the New World Screwworm Fly, Inferred by Approximate Bayesian Computation Analysis

Insect pest phylogeography might be shaped both by biogeographic events and by human influence. Here, we conducted an approximate Bayesian computation (ABC) analysis to investigate the phylogeography of the New World screwworm fly, Cochliomyia hominivorax, with the aim of understanding its population history and its order and time of divergence. Our ABC analysis supports that populations spread from North to South in the Americas, in at least two different moments. The first split occurred between the North/Central American and South American populations in the end of the Last Glacial Maximum (15,300-19,000 YBP). The second split occurred between the North and South Amazonian populations in the transition between the Pleistocene and the Holocene eras (9,100-11,000 YBP). The species also experienced population expansion. Phylogenetic analysis likewise suggests this north to south colonization and Maxent models suggest an increase in the number of suitable areas in South America from the past to present. We found that the phylogeographic patterns observed in C. hominivorax cannot be explained only by climatic oscillations and can be connected to host population histories. Interestingly we found these patterns are very coincident with general patterns of ancient human movements in the Americas, suggesting that humans might have played a crucial role in shaping the distribution and population structure of this insect pest. This work presents the first hypothesis test regarding the processes that shaped the current phylogeographic structure of C. hominivorax and represents an alternate perspective on investigating the problem of insect pests. © 2013 Fresia et al.

Os cadernos de física: algumas inquietações sobre o currículo oficial do Estado de São Paulo

The assumptions of Marxist philosophy helps us understand the inherent contradictions of the historical process. The category mode of production is understood as the means and the ends for which mankind produces and reproduces reality objectively and subjectively. The temporal evolution of the mode of production has spurred antagonistic social classes, which are the world capitalist bourgeoisie and proletariat. At the rise of the current mode of production each class produced a pedagogy according to your interests. The proposal of the workers is centered on unity between teaching and non-alienated labor, enabling the development of human potential and building a new social order. The last historical period was marked by the implementation of the neoliberal agenda to reduce social spending and market liberalization. The educational reforms of the state of São Paulo followed the same goals. From the program São Paulo Faz Escola, São Paulo School Curriculum was introduced in the State of São Paulo, which integrates several documents. The Student Notebook, separated by discipline and delivered bimonthly to students of public schools, is one of those publications. Specifically, the physics notebook brings a content with no depth, where theories are presented by minimizing the mathematical formalism for a broad education that meets the needs for dynamize the economy
