25. DIVERSIDADE DE ESPÉCIES FLORESTAIS ARBÓREAS ASSOCIADA AO SOLO EM TOPOSSEQÜÊNCIA DE FRAGMENTO DE MATA ATLÂNTICA DE PERNAMBUCO
The objective of this research was study the floristic and the phytosociology in a fragment of Atlantic Wood Forest, known Tejipió Forest, in Recife Pernambuco, Brazil, in order to define the ten most valuable important (IV) species and to know the arboreos vegetal community to better understand and its population behavior and structure, in the area as a wh

26. Evolução geologica das rochas maficas e ultramaficas no Greenstone Belt Barbacena, região de Nazareno, MG
The study area is located at the southem border of the São Francisco Craton and shows plutonic, vo1canic and sedimentary rocks, of Archean to Mesoproterozoic age, reworked by later thermo-tectonic events. Two different groups of mafic and ultramafic rocks occur in this region. The first is a komatiite-tholeiite sequence belonging to the Barbacena Greenstone

27. Estudo floristico e fitossociologico de um trecho de mata ciliar do Rio Paraguai, Pantanal-MS, e suas relações com o regime de inundação
A floristic and phytosociological study was carried out in a galIery forest of the Paraguay river near Corumbá and Ladário - MS, Brazil. Structural aspects of the forest were correlated to the flooding of the river, and the dynamics and some caracteristics of dispersion of the species were evaluated. The floristic survey comprised an area of about 22 km al

28. Sucessão e ecologia de populações de insetos associados a decomposição de carcaças de suinos expostas em ambiente natural de mata mesofila semidecidua, Campinas-SP
The existence of sarcosaprophagous insects specialIy Calliphoridae and Sarcophagidae families, is known a long time ago, however, the successional pattern of them in carcass only has been studied recently in tropics. The present study was done at "Reserva Mata de Santa Genebra", Southeastern Brazil, and some aspects of succession, diversity, relative abundan

29. Índices de vegetação e valores de proporção na caracterização de floresta tropical primária e estádios sucessionais na área de influência da Floresta Nacional do Tapajós-Estado do Pará / Vegetation indices and fraction values to characterize primary rainforest and sucessional stages in the area of influence of Tapajos National forest - Para State
In May 1995, a field campaign was carried out in the innerside and proximities of Tapajós National Forest - Pará State, aiming to measure dendrometric variables and leaf area index (LAI) in vegetation communities of tropical rainforest and regrowth, represented by three stages, c1assified in function of age: less than 5 years; 5 to 10 years and more than 1

30. Germinação, crescimento, atividade fotossintetica e translocação de compostos de carbono em especies arboreas tropicais : estudo comparativo e influencia de sombreamento natural
Gennination, growth, photosynthesis and translocation of carbon in tropical tree species: a comparative study and the influence of natural shade. Light has been recognized as a major factor in species replacement during secondary sucession in forests. The degree of shade tolerance may be important in detennining successional sequences, since these are condit

31. Fitossociologia e dinamica do estrato herbaceo de dois fragmentos florestais do Estado de São Paulo
A phytosociological study of the herbaceous layer was carried out in two forest areas. One is a 42 hectares remnant of gallery forest in Brotas and the other, a 250 hectares reserve of semideciduos forest in the municipality of Campinas, both in the state of São Paulo (SP). The phytosociological method was based on 50 plots of 2x1 m, irregularly distributed

32. Ecologia de pequenos mamiferos da mata Atlantica : seleção de habitats na reserva biologica de Poço das Antas (R.J.)
In order to obtain a quantitative approach of the differential ecological use of the available macrohabitats, in the main stages of secondary plant sucession of the Atlantic Forest in the State of Rio de Janeiro. This study was divided in three parts: (I) montlhy sampling by mark-release method in four macrohabitats in the boundaries of the Biological Reserv
