13. Besouros escarabeÃneos em fragmentos de Floresta AtlÃntica do Centro de Endemismo Pernambuco
Habitat fragmentation alters the dynamics of tropical tree assemblages, being able to modify the dung beetles communities. The objective of this research was to determine how the fragments metrics and functional attributes of trees assemblages influence the dung beetles communities in Atlantic forest fragments of northeastern Brazil. The collecting of dung b

14. Padrões e processos ecológicos do componente arbóreo em uma área de floresta estacional semidecidual (Araguari, MG) / Ecological Patterns and Processes on the Tree Layer in a Seasonal Semideciduous Forest (Araguari, MG)
This thesis deals with the study of the tree component in a seasonal semideciduous forest (FES) with a good state of conservation. Initially, it was prepare a general introduction, showing the importance of the detailing study of forests well preserved, as comparative basis with disturbed forests. After this context, the thesis has been divided into two chap

16. Floristic composition and phytosociological structure of a seasonal semideciduous forest in Araras, São Paulo state / Composição florística e estrutura fitossociológica de uma floresta estacional semidecidual em Araras, SP
The purpose of this study was to analyze the specific composition of tree, arboreal structure, infestation by climbers, canopy layer and compare the results with other forest fragments and, from these, to form a data bank for monitoring. The forest studied is located in the geographical coordinates S 22 17 and W 47 24. The soil is red-dark Latosoil type and

17. Macrófitas aquáticas submersas: fotossíntese, crescimento e variáveis abióticas da água/
Cabomba furcata and Egeria najas are rooted submerged species of aquatic macrophytes that occurred in Oleo Lagoon (21 36 S e 47 49 W), Mogi-Guaçu river floodplain (Ecological Station of Jataí, Luiz Antônio, SP). Limnological characteristics of the water and the net photosynthesis of C. furcata were determined in Oleo lagoon at the rainy and the dry period

18. Composição, estrutura e aspectos ecológicos da mata ciliar do Rio Araguari no Triângulo Mineiro / Composition, structure and ecological aspects of forest riparian the Araguari River within Triângulo Mineiro region
The study aimed to characterize the tree-shrub community of a riparian forest, one of the last remnatns on the Araguari River, at Uberlândia, Triângulo Mineiro region, Minas Gerais State. The composition, horizontal and vertical structure were investigated by phytosociological survey of 110 plots of 10m x 10m (1,1ha). All trees with CAP ` 15 cm were regist

19. Floristic, structure and successional stages of native fragments of the Atlantic Forest in Minas Gerais / FlorÃstica, estrutura e estÃdios sucessionais de fragmentos nativos da mata atlÃntica em Minas Gerais
A floristic study was carried out in 4 forest fragments subjected to different treatments. Two fragments were subjected to a management plan (one of them for 14 years and the other for 9 years), the third one was clear cut and burnt 22 years ago, and the last fragment (control) for which there is no record of strong intervention. The objectives of this study

20. 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

21. Estrutura etária e distribuição espacial de Myrcianthes pungens (O. Berg) Legrand (Myrtaceae) em um trecho de mata ciliar do rio da Prata, no município de Jardim, Mato Grosso do Sul
The objective of this study was to evaluate the size structure and spatial distribution model of the arboreal species Myrcianthes pungens (O. Berg) Legrand, (Myrtaceae). This is a climax, shade-tolerant semideciduous species, which is distributed from the states of Mato Grosso do Sul and São Paulo to the northern Uruguai. It is actually classified as a thre

22. Floristica, Fitossociologia e Heterogeneidade em um povoamento com predominÃncia de Anadenanthera peregrina (Benth.)Speg. / FLORÃSTICS, PHYTOSOCIOLOGY AND HETEROGENEITY IN A STAND WITH PREDOMINANCE OF Anadenanthera peregrina (Benth.) Speg
The present study was developed in an ancient abandoned area of planting of Anadenanthera peregrina, on the campus of the Federal University of Lavras, MG of about 7,56ha. It was aimed to report the floristic composition of this area as well as its phytosociological structure, paying attention to the ecologic aspects of the species, as the regeneration, disp

23. Estudo de liquens corticícolas foliosos em um mosaico de vegetação no sul do Brasil / lichens;forest;Araucaria angustifolia
Lichens are important epiphytic components of forests, however anthropogenic alterations of forest habitats could lead to substantial modifications in the diversity and species spatial distribution of lichens. This work investigates how species composition, richness, abundance, diversity and vertical distribution of lichens in tree trunks could be modified w

24. Crescimento e atividade fotossintetica em duas especies de lianas de uma floresta estacional semidecidual
The lianas are copious in natural and man-made clearings and it appears that these forms of life require high irradiance for development and growth. Lianas are rooted in the soil and use other plants, especially trees as support. Since these plants begin their growth on the forest floor, then ascend to the canopy, they can experience extreme differences in r
