1. Composition and Functional Diversity of the Urban Flora of Alfenas-MG, Brazil
ABSTRACT Urban tree cover has important environmental and social functions and can act as ecological refuges. The objective of the present study was to investigate the taxonomic and functional diversities of urban plant communities in Alfenas, Minas Gerais State, Brazil. We sampled all trees DBH ≥ 3 cm in eight different urban green areas, recording 1,138

2. High-level phylogeographic structuring of Neoleucinodes elegantalis Guenée (Lepidoptera, Crambridae) in Brazil: an important tomato pest
ABSTRACT Neoleucinodes elegantalis is an important tomato pest in Brazil, occurring throughout the country and resulting in economic losses in agriculture. In several species, biogeographic studies in Brazil indicate the structuring of populations, following the refuge model, with a split between the populations of the northeast and the southeast regions of

3. Reproductive aspects of Hyalella carstica (Amphipoda: Hyalellidae) in a natural environment in southeastern Brazil
Abstract The reproductive aspects of populations are important determinants of their ability to maintain themselves throughout time. In the case of amphipods from the genus Hyalella Smith, 1874, the reproductive period is easily determined by the presence of ovigerous females and pre-copula pairs in the population. This study evaluated the fecundity, pairing

4. Evaluation of natural foci of Panstrongylus megistus in a forest fragment in Porto Alegre, State of Rio Grande do Sul, Brazil
Introduction Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil. The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and tria

5. Filolegrafia e fluxo gênico em espécies do gênero Caryocar / Phylogeograghy and gene flow in species of Caryocar genus
O gênero Caryocar é composto por espécies arbóreas, distribuído na região neotropical. A maioria das espécies do gênero ocupa biomas florestais, porém três espécies se distribuem na diagonal seca que corta os dois biomas de floresta tropical brasileira sendo elas C. brasiliense, C. coriaceum e C. cuneatum. Entender o padrão filogeográfico dessas

6. Microhabitat use by species of the genera Bothrops and Crotalus (Viperidae) in semi-extensive captivity
Many factors influence microhabitat including climate and the occurrence of predators, prey and suitable shelters. The influence of predators in a semi-extensive breeding system is minimized due to frequent monitoring of the area. This situation enables the independent analysis of such other variables as refuges and temperature. Some specimens of the Viperid

7. Efeitos da rugosidade de substratos, distúrbios físicos e organismos pastejadores na estruturação de assembleias de algas bênticas e na biomassa perifítica em um riacho subtropical : uma abordagem experimental
Os estudos apresentados nesta tese tiveram como objetivo compreender aspectos da organização de assembleias de algas bênticas em riachos. Foi avaliado especificamente o efeito da heterogeneidade de habitat na escala de rugosidade de substratos e sua interação com distúrbios hidrológicos e organismos pastejadores (grazers). Utilizou-se uma abordagem ex

8. Spider diversity in a rice agroecosystem and adjacent areas in southern Brazil / Diversidad de arañas en un agroecosistema de arroz y áreas adyacentes en Brasil meridional
Las arañas son uno de los grupos de depredadores terrestres más numerosos que se encuentran en diversos ambientes tales como agroecosistemas y áreas circundantes. Es importante investigar los cambios en diversidad de arañas en agroecosistemas debidos al manejo agrícola. Este trabajo evaluó riqueza, abundancia, y similitud de arañas en diferentes etapa

9. Presence of the fire ant Solenopsis invicta (Westwood) (Hymenoptera: Formicidae) stimulates burrowing behavior by larvae of the sandfly Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae)
The sandfly Lutzomyia longipalpis (Lutz & Neiva) vectors leishmaniasis in the neotropics. Although much is known about the biology of adult flies, little is known about interactions with its natural enemies. Here, we examined behavior of larvae of L4 L.longipalpis on a soil substrate when exposed to the fire ant Solenopsis invicata (Westwood). When ants were

10. The community of medium and large mammals in fragments of Atlantic Forest in the environmental protected area of Campinas, São Paulo state / Comunidade de mamiferos de medio e grande porte em fragmentos de mata semidecidual da APA municipal de Campinas, SP
I evaluated the medium and large mammal community in 13 small fragments (1 to 12ha) and a control (220ha) in the Environmental Protected Area of Campinas, São Paulo state. The community was sampled using baited track stations (Pro s Choice and Canine Call bait) over a year (once each quarter) from July 2007 to June 2009, giving 15 to 170 track-station night

11. 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

12. Hospitalidade e reconhecimento da diferença na transnacionalização dos direitos humanos. A crise da alteridade na questão dos apátridas e refugiados
O problema dos apátridas e refugiados de guerra, no panorama mundial, é um dos entraves onde mais podemos observar a crise de sentido que atravessa as relações humanas na modernidade recente. Constata-se a insuficiência da concepção abstrata de direitos humanos tradicional. O presente trabalho procura estabelecer um novo ponto de partida para esta que
