1. Cerrado sensu stricto sobre Neossolo Quartzarênico : fitogeografia e conservação
The Cerrado biome presents a large spatial heterogeneity and is characterized as having elevated beta diversity. The Sete Cidades National Park (PNSC) and Chapada Grande Meridional, both located at the state of Piauí, show great landscape diversity with different physiognomies and soils types. In this study, we investigated the woody vegetation of the cerra

2. Avaliação da sustentabilidade nutricional de plantios de Pinus taeda L. usando um balanço de entrada-saída de nutrientes / An input-output budget to estimate the nutritional sustainability of Pinus taeda L. plantations
The knowledgement of the nutritional sustainability of the practices used in plantations is necessary for its adequate management, mainly when used in low fertility sites, with slash-burning, and with no fertilizer application, like P.taeda plantations in south of Brazil. Given the increasing importance of the species, a study was done to investigate the nut

3. Distribuição geografica, forofitos e especies de bromelias epifitas nas matas e plantações de cacau da região de Una, Bahia
The loss of species is a natural outcome when habitats are fragmented or changed. Nevertheless, epiphytes would be particularly susceptible to this process given the high number of species with limited geographical distribution. In modified habitats changes are ais o expected in the species composition and differences in the overall abundance in the organism

4. Seed rain, seed bank and natural regeneration under three species of early succession in a restored area at Iracemápolis (SP). / Chuva de sementes, banco de sementes e regeneração natural sob três espécies de início de sucessão em uma área restaurada em Iracemápolis (SP).
The present study describes the composition of natural regeneration, seed rain and seed bank under three early species - Centrolobium tomentosum Guill. ex Benth. (Fabaceae), Cordia myxa L. (Boraginaceae) e Melia azedarach L. (Meliaceae) and evaluatuation of the possible differences among understory regeneration. The study area, a restored area, is located

5. Growth periodicity and formation of wood of some tree species of semideciduous seasonal forest in the southeast region of the state of São Paulo. / Periodicidade do crescimento e formação da madeira de algumas espécies arbóreas de florestas estacionais semidecíduas da região sudeste do estado de São Paulo.
The dendrocronology and dendroclimatology studies are now being used in the tropical and subtropical Brazilian forest. These studies are important to correlate the growth rate of forest species with climatic conditions and phenological behaviour to determine the age of the trees. This way, this investigation had as main objectives: (i) study the cambial peri
