1. Soil Seed Banks in a Forest Under Restoration and in a Reference Ecosystem in Southeastern Brazil
ABSTRACT The current study aims to characterize the soil seed banks in a forest under restoration and in a seasonal semideciduous forest remnant, as well as to quantitatively and qualitatively compare them in order to evaluate the seed bank potential to influence the restoration process. In total, 60 samples of soil seed banks were collected in two adjacent

2. Aspectos ecológicos das espécies regenerantes de uma floresta urbana com 150 anos de sucessão florestal: o risco das espécies exóticas
Resumo A presença de florestas dentro de centros urbanos tem grande importância, principalmente devido aos serviços ecossistêmicos proporcionados por elas. Fragmentos urbanos são pouco estudados e trabalhos quantitativos focados na flora arbórea na área do presente estudo nunca foram realizados. O objetivo foi avaliar a composição, estrutura e diver

3. Functional morphology of subtropical tree seedlings in southern Brazil
Resumo O objetivo deste estudo foi analisar os atributos morfofuncionais das espécies da Floresta Ombrófila Mista, pertencentes a diferentes categorias sucessoriais. Frutos foram coletados de remanescentes florestais em Curitiba, Paraná. Foi realizada a biometria das sementes e plântulas e estimados os seguintes índices: comprimento da parte aérea/plâ

4. Structure and floristic diversity of remnant semideciduous forest under varying levels of disturbance
The perturbation of Neotropical forests generates large disturbances in biological communities. The species that suffer least from the resulting habitat fragmentation are the pioneers, because they possess greater ability to inhabit disturbed environments. Therefore, it is expected that species diversity will be greater in areas subjected to intermediate dis

5. Influência do desenvolvimento florestal sobre a comunidade edáfico-epígea de Arthropoda e a mirmecofauna: bases para a bioindicação do processo sucessional na restauração ecológica / The influence of forest development on edaphic and epigeic Arthropod communities and ant fauna: bases for bioindicantion of successional process in ecological restoration
A restauração ecológica visa o estabelecimento de ecossistemas semelhantes aos que originalmente ocupavam uma determinada área que foi degradada. Todavia, os resultados dos esforços envolvidos na restauração e no retorno dos processos ecológicos naturais são difíceis de serem medidos, pois faltam métodos apropriados. Os bioindicadores são ferrame

6. Processo de decomposição e padrão sucessional de artrópodes em carcaças de suínos expostas em locais abrigados e desabrigados / The process decomposition and the successional pattern of arthropods in pig carcasses exposed to unsheltered environments
Forensic Entomology uses data, mainly from carrion insects, to estimate the Post Mortem Interval (PMI). The oviposition pattern of these insects can be influenced by several factors, such as the presence of materials in the vicinity of the body, whether the corpses are buried, burned or disposed in open or closed environments, etc. These factors can affect t

7. Drought resistance in seedlings tree species of semideciduous tropical forest / Resistência à seca em plântulas de espécies arbóreas da floresta estacional semidecídua
The rainfall is high in tropical forests, but there is great variation in water availability to plants. On a local scale, this availability may vary depending on the location of individuals in gaps, their position in the landscape and soil composition. On a regional scale, variations related to the volume and distribution of rainfall, coupled with seasonal c

8. Sucessão secundária em áreas de Mata Atlântica de Pernambuco : mudanças florísticas e estruturais
Secondary forests have been considered as priority areas for conservation in tropical regions due to their possible role as buffer zones. They serve as habitats for plants and animals coming from destroyed mature forests and as corridors between forest fragments. They also have the capacity to accumulate biomass and nutrients at high rates, to maintain bioge

9. The process of natural regeneration and ecosystem restoration in former forest production areas / O processo de regeneração natural e a restauração de ecossistemas em antigas áreas de produção florestal
In Forest Companies that cultivate fast-growing forest species for industrial supply, it has been usual the existence of commercial production areas that need to be converted in protected areas with native vegetation. Nevertheless, depending on local conditions and landscape context, the natural regeneration process is not enough to guarantee the successiona

10. Aspectos da estrutura fitossociológica e silvigenética em fragmentos de floresta estacional semidecídua com diferentes histórias de perturbação em Botucatu, SP / Aspects of the phytossociological and silvigenetic structure of seasonal semi deciduous forest fragments with different disturbance histories, at Botucatu, SP
The seasonal semi deciduous forest fragments in São Paulo State suffered the fragmentation process mainly because agricultural and urban expansion. These remnants are very important for taxonomic and ecological studies, although they are much altered. By joining phytossociological and silvigenetic studies is possible a diagnosis of their present situation,

11. Use of stabilized sewage sludge in revegetation of a decapitated soil / Uso de lodo de esgoto estabilizado na revegetação de um solo decapitado
One of the consequences of urban population growth was the emergence of various environmental problems in the most of urban cities in Brazil, mainly the deterioration of water resources and land degradation caused by inadequate disposal of various types of waste generated by cities. In order to evaluate the use of sewage sludge composted with waste of grass

12. ESTRUTURA E COMPOSIÇÃO DO ESTRATO ARBÓREO EM DIFERENTES TRECHOS DA RESERVA BIOLÓGICA MUNICIPAL SANTA CÂNDIDA, JUIZ DE FORA-MG
The anthropogenic disturbances as coffee plantation in the Zona da Mata of Minas Gerais were main factors to the elimination of the vegetal coverage. After the reduction human activities in Juiz de Fora, there was the recovery of degraded ecosystem, resulting on secondary forests.
