25. Demografia e variação genética de Puma concolor (Linnaeus, 1771) na região nordeste do estado de São Paulo
The northeast area of São Paulo state was originally covered by cerrado and semideciduous forest, but for the last two centuries, it has experienced distinct cycles of human exploitation of its fertile soils. Despite of intensive human activities, large habitat loss and fragmentation of the native vegetation cover, pumas (Puma concolor) still inhabit remnan

26. Distribution of Lymnaeidae (Mollusca: Pulmonata), intermediate snail hosts of Fasciola hepatica in Venezuela
An extensive malacological survey was carried out between 2005-2009 in order to clarify the exact number of lymnaeid species which may be intermediate hosts of Fasciola hepatica in Venezuela. Four species were discovered during this survey, including two local species: Lymnaea cubensis and Lymnaea cousini and two exotic species: Lymnaea truncatula and Lymnae

27. O plÃsmon da regiÃo de recobrimento da ligaÃÃo quÃmica como ferramenta para caracterizaÃÃo de materiais
Important issues can be raised about the possibility of relations between macroscopic properties of materials and concepts, introduced recently, of the chemical bond overlap polarizability (PR) and the concept of ionic specific valence (VIE). A proposal in which the overlap region of chemical bond is considered as a âplasmon‐likeâ charge distribution

28. Inverse problem in proton-proton elastic scattering in the impact parameter representations / Problema inverso do espalhamento elastico proton-proton na representacao de parametro de impacto
The Impact Parameter and Eikonal Representations are investigated by means of an empirical analysis of the experimental data on proton-proton elastic scattering, at the highest energy region with experimental information available (six data sets at center of mass energies 19.4 - 62.5 GeV). Making use of a novel model-independent parametrization for the scatt

29. Análise da Microestrutura de Escamas de Serpentes Xenodontinae em Associação à Ocupação de Diferentes Microhabitats. / Analysis of the Microstructure of Xenodontinae Snake Scales Associated to Different Habitat Occupation Strategies.
The morphology of many organisms seems to be related to the environment they live in. Nonetheless, many snakes are so similar in their morphological patterns that it becomes quite difficult to distinguish any adaptive divergence that may exist. Many authors suggest that the microornamentations on the scales of reptiles have important functional value. Here,

30. Análise morfométrica e variabilidade morfológica em populações de Syngonanthus nitens (Bong.) Ruhland (Eriocaulaceae) / Morfometric analysis and morphological variability in populations of Syngonanthus nitens (Bong.) Ruhland (Eriocaulaceae)
Syngonanthus nitens (Bong.) Ruhland (common name "Golden Grass") is a widespread distributed species in Brazil. The handcrafts are made from scape of S. nitens, which are bright and gold in color. The identity of this taxon has been questionable, since plants with very different morphological patterns are identified as belonging to the same species. These in

31. Construção de cDNA infeccioso de Citrus Sudden death-associated virus
The orange is an important fruit, widely spread around the world and very well suited to the climate in Brazil. However, citriculture has suffered a lot with a new disease, called Morte Súbita dos Citros (MSC) (Citros Sudden Death Disease) that has been recognized the first time in 2001 in Minas Gerais State, Brazil. The disease cause severe damages to plan

32. Habitat partition among cervids in the Iguaçu National Park / Partição de habitats entre os cervídeos do Parque Nacional do Iguaçu
This study evaluated the determinant patterns of spatial distribution among the sympatric species Mazama americana and Mazama nana in the Iguaçu National Park under the principles of competitive exclusion and coexistence of ecologically related species. Three potential models of habitat partition were proposed to evaluate the relations among the occurrence

33. Estratigrafia e petrogênese das sequências vulcânicas paleoproterozóicas na região de São Félix do Xingu (PA), Província Mineral de Carajás / Stratigraphy and petrogenesis of the paleoproterozoic volcanic sequences in the São Félix do Xingu (PA) region, Carajás Mineral Province
Near the São Félix do Xingu city, centersouth portion of the Pará state, in the context of the Carajás Mineral Province, occur extensive Paleoproterozoic volcanoplutonism (1.88 1.87 Ga) exceptionally well-preserved and grouped in the Sobreiro and Santa Rosa formations. These suites are generically correlated to Uatumã Supergroup volcanoplutonism, a magm

34. Regeneração natural de espécies arbóreas em fragmento florestal da Zona da Mata Mineira / Natural regeneration of tree species in a Mountain Seasonal Semideciduous Forest fragment in the Atlantic Forest domain, southeastern Brazil
Tree species natural regeneration floristic composition was studied in a Mountain Seasonal Semideciduous Forest fragment in the domain of the Atlantic Forest, in southeastern Brazil (2045 S, 4255 W) to subsidize forest management. Ten sites were selected based on aspect, slope and topographic position. Natural regeneration indexes were estimated for each tre

35. Niche characterization of Sporophila spp. (Aves: Emberizidae) and its relation to microhabitat in palm swamp areas near Uberlândia, MG / Caracterização de nicho de Sporophila spp. (aves: Emberizidae) e sua relação com a estrutura de microhabitat em áreas de vereda de Uberlândia, MG
The relative importance of each environmental factor in structuring birds community seems to be variable, and each species exhibits a distinct and specific response to environmental characteristics and their changes. Some granivorous birds can perform seasonal migrations in search of good seeds. They often include the brazilian cerrado, both for breeding and

36. Analysis on the limitation of the law in the solution of environmental conflicts: the use of geographic information systems in judicial proceedings / Análise das limitações do direito na solução de conflitos ambientais: a aplicação de sistemas de informações geográficas a processos judiciais
There is a hiatus between the environmental law existence, mainly because of its great rigidity, and the fact of being considered an impediment to the economic development. The Permanent Preservation Areas (PPA) and Legal Forest Reserve (LFR) are institutes created by the Environmental Law that limit the economic exploitation in rural properties without an i
