The analysis of the influence of edaphic finer textures, as a facilitating factor for the expansion of forest formations in the absence of fire, was possible thanks to rare characteristics found in a savanna fragment located in the State of São Paulo, Brazil. The total suppression of fire for over four decades, and the occurrence of two savanna physiognomies, cerrado sensu stricto and cerradão,...

Two siblings suffering from mental retardation, progressive bronchiectasis, extensive warts, and persistent hepatitis B are described. The propositus also had an unusual physiognomy and non-specific colitis. Both patients had a marked decrease in the population of CD4+ helper T cells.

Ectodermal dysplasia is a rare hereditary disorder. Its Hypohidrotic (HED) variant is also known as ChirstSiemens-Touraine syndrome. It is inherited as an Xlinked trait. Such Patients are characterized by the clinical manifestations of Hypodontia, Hypotrichosis, Hypohidrosis and a highly characteristic facial physiognomy. This article, reports a typical case of Hypohidrotic Ectodermal Dysplasia...

The importance of fire in the creation and maintenance of mesic grassland communities is well recognized. Improved understanding of how grasses--the dominant clade in these important ecosystems--will respond to alterations in fire regimes is needed in the face of anthropogenically driven climate and land-use change. Here, we examined how grass communities shift in response to experimentally man...

The Brazilian savanna, locally known as "cerrado", is the most intensely stressed biome with both naturaland human-induced pressures. In this study, we aimed to improve discrimination and characterization of the Brazilian cerrado physiognomies using hyperspectral Hyperion imagery, the first space-borne imaging spectrometer onboard the NASA's Earth Observing-1 (EO-1) platform. A Hyperion image w...

In any theocratic and monotheistic system, the female image is represented as a sexual entity, reduced to its most material physical dimension, avoiding intellectual or psychological peculiarity. The objective of following article describe analyze categorization, without modesty, women according their aptitude and, for this, we focus on physiognomic text bequeathed by Syrian writer al-Shayzarī ...

Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring variation in floristic diversity and phylogenetic s...

Gosling & Bush (2005) criticize our interpretation (Wüster et al. 2005) of a phylogeographic analysis of the Neotropical rattlesnake (Crotalus durissus) as supporting a hypothesis of Pleistocene fragmentation of the Amazonian rainforests. We thank these two authors for the opportunity to further discuss issues concerning the ecological and biogeograph-ical history of the Amazon Basin. Gosling a...
