13. Estrutura populacional e alometria reprodutiva de Podocnemis expansa (Testudines, Podocnemididae) no entorno do Parque Nacional do Araguaia, Tocantins / Population structure and reproductive allometry of Podocnemis expansa (Testudines, Podocnemididae) around the Parque Nacional do Araguaia, Tocantins
Among the reptiles found in the Amazon, the turtles stand out because of its diversity and economic importance. Podocnemis expansa, popularly known as Amazon river turtle, is considered the largest freshwater turtle in South America and has been heavily exploited for centuries by many indigenous and riverine communities. This study aimed to expand the knowle

14. Ecology, behavior and natural history of the harvester ant Pogonomyrmex naegelii (Formicidae, Myrmicinae) in cerrado vegetation: activity schedule, diet, home range, nest structure and demography / Ecologia, comportamento e história natural da formiga ceifeira Pogonomyrmex naegelii (Formicidae, Myrmicinae) em cerrado : ritmo biológico, dieta, área de vida, estrutura e demografia dos ninhos
Pogonomyrmex naegelii belongs to the group known as harvester ants, which collects and stores seeds in underground chambers for later consumption. These ants can be found in both warm temperate and tropical regions around the world, especially in areas of semiarid to arid vegetation, although they may also be found in moist habitats. The following study prov

15. Liberdade e não-liberdade em o conceito de angústia de SØREN KIERKEGAARD / Liberté e Non-liberté dans le Concept dAngoisse de Søren Kierkegaard
Lobjectif de notre étude est de faire une analyse dinterprétation de loeuvre Le Concept dAngoisse (Begrebet Angest, 1844) de Kierkegaard, particulièrement des phénomènes de liberté et de non-liberté. Nous avons commencé la recherche par une tentative dexplication de la méthode de communication indirecte, utilisée par le philosophe. En effet, nous i

16. ASSEMBLÉIAS DE FORMIGAS DO PARQUE ESTADUAL DO ITACOLOMI (MG) E RELAÇÕES INTRA E INTERESPECÍFICAS ENTRE ESPÉCIES DOMINANTES
Arboreal ants usually show a strong territolialist behavior, defending aggressively their foraging sites or the area surrounding their nest against individuals of other colonies. Thereby, the most aggressive ants with larger distribution, which may be considered dominants, defines the ant assemblage structure by shaping species distributions into threedimens

17. Estrutura genética e sociogenética das populações e ninhos de Euglossini (Hymenoptera: Apidae) determinadas por meio de microssatélites.
Euglossine bees are important pollinators of many Neotropical plant species, particularly orchids which could present a species-specific bee-flower relationship, essential to the reproductive success of these plants. Orchids produce chemical compounds to attract males of Euglossine bees (the effective pollinators of the orchids), and these compounds were iso

18. Artificial nest predation: application, challenges and perspectives for the tropical areas / Predação de ninhos artificiais: aplicações, desafios e perspectivas para as áreas tropicais
The natural predation of the nests has been suggested as the principal cause to the decline of bird population, acting on the performance and community structure. Due to the difficulty of natural nest localization and monitoring, the artificial nests are used as a fast alternative to check the avian reproductive success. The artificial nest studies are widel

19. AnÃlise da estrutura genÃtica e biologia reprodutiva do papagaio-verdadeiro (amazona aestiva)
Information on biology, ecology and genetic variability of a specie are ultimate to subsidize the elaboration of strategies of conservation of its natural populations. The blue-fronted amazon (Amazona aestiva) presents a widespread distribution and is still abundant in some areas of occurrence, therefore it is not under threat of extinction. However, it is o

20. Melodrama e NaÃÃo no Cinema Brasileiro dos Anos 1940 / Melodrama and Nation on Brazilian Cinema of the Forties
I wanna to realize an approach about brazilian film production linked with Estado Novo values. The movies are the feature films Birds without Nest (1939) by Raul Roulien, Clay (1940) by Humberto Mauro and Forbidden Romance (1944) by Adhemar Gonzaga. My key matter is to show the easy or difficult relations of those ideological values with the melodramatic str

21. Modelos computacionais para o processo de forrageamento e facilitação social em cupins / Computer models to social facilitation and foraging process in termites
There is much current interest in understanding the dynamic principles that generate patterns in space and time. In biology, the complexity of self-organized patterns are seen from colonies of bacterias, of social insects to the human society. Among these, animal foraging patterns associated to the strategies of systematic search for food sources are include

22. Formigas cortadeiras (Hymenoptera, Formicidae) como agentes modificadores da disponibilidade de luz e da estrutura da comunidade vegetal em Floresta AtlÃntica Nordestina
Leaf-cutting ants of the genus Atta are important generalist herbivores of the Neotropics, with many species showing a marked preference for early successional plants. Previous studies have revealed that their enormous nest constructions (up to 200 m2) locally affect the abundance and species richness of the plant community. Moreover, leaf harvesting activit

23. DesnutriÃÃo experimental e treinamento fÃsico: estudo de parÃmetros murinomÃtricos de ratas gestantes e dos conceptos
The period of conception to the birth is characterized by fast growth, replication, cellular differentiation, and maturation of organs and systems. A stimulus or insult when applied at a critical or sensitive period of development results in a long-term effects of on the structure or function of the organism. The present study had as objective establishes a

24. Discurso político: a constituição do presidenciável Luiz Inácio LuLa da Silva como sujeito dicursivo
Ce travail a pour but expliquer la constitution de Luiz Inácio Lula da Silva, comme sujet discursif au cours de sa trajectoire politique, focalisant les campagnes présidentielles de 1989 et 2002. Dabord, nous commencerons du concept de discours, et des rapports inter et intra-discursifs où le sujet discursif se trouve, pour qui nous puissions dévoiler sa
