1. Um novo ecossistema: florestas urbanas construídas pelo Estado e pelos ativistas
resumo Historicamente, a expansão das cidades resultou na substituição da paisagem natural pela urbana, tendo como consequência a degradação ambiental por meio das mudanças na cobertura do solo, nos sistemas hidrológicos, nos ciclos biogeoquímicos, no clima e na biodiversidade, tornando as cidades especialmente vulneráveis às mudanças climáticas

2. The challenge of restoring tropical freshwater ecosystems
Resumo Vivemos um processo mundial crescente de degradação das bases de sustentação da vida. No Brasil esta ameaça se intensifica pela fragilização crescente das estruturas de proteção ambiental. A restauração ecológica é uma alternativa para enfrentar a degradação dos ambientes aquáticos. Ela tem sido empregada em maior escala nas regiões d

3. Functional patterns of tree communities in natural Araucaria forests and old monoculture conifer plantations
ABSTRACT A functional perspective of tree communities is helpful for understanding forest dynamics, especially vegetation recovery after other land uses. Knowledge about ecological filters and survival strategies of trees are also important for the restoration of degraded areas. This study aimed to evaluate the functional composition and structure of adult a

4. 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

5. Uso de mantas geotêxteis na revegetação de um fragmento de mata de galeria no Jardim Botânico de Brasília - DF: sobrevivência e desenvolvimento de mudas
Resumo Atividades antrópicas têm causado danos ao Cerrado, segundo maior bioma do Brasil. Entre as formações vegetais mais ameaçadas do bioma Cerrado, destaca-se a Mata de Galeria. Programas de recuperação tentam restaurar essa fitofisionomia, mas ervas invasoras dificultam o estabelecimento e o desenvolvimento de espécies nativas lenhosas. Nesse cen

6. Restoring Ecological Functions Using Agroforestry Systems in Riparian Forests
ABSTRACT Agroforestry systems and restoration models were compared with native forests by examining the restoration of ecological processes that generate stability, resilience and reliability. The stability assessment was obtained using indicators of diversity, structure and functionality. Indicators of soil protection and nutrient cycling were also used to

7. Ex situ initial seedling development of Hymenaea courbaril L. (Fabaceae): a crucial phase to preserve the species
RESUMO Hymenaea courbaril L. é uma importante espécie Neotropical, que aparece com baixa densidade populacional, restrita a fragmentos de florestas semidecíduas, com baixa mortalidade e baixo recrutamento. Assim, algumas questões orientaram os objetivos deste trabalho, incluindo a capacidade de sementes armazenadas para formar mudas normais. Sementes col

8. Patologia de Sementes Florestais: Danos, Detecção e Controle, uma revisão
RESUMO A demanda por sementes com boa qualidade fisiológica e sanitária, com o propósito de produzir mudas sadias de espécies florestais nativas, cresceu nos últimos anos, em função da restauração de florestas, recuperação de áreas degradadas, recomposição de paisagens e matas ciliares. Poucas pesquisas têm sido desenvolvidas na área de sanid

9. Restoration Strategies in an Area Invaded by Pteridium aquilinum (L.) Kuhn
ABSTRACT Pteridium aquilinum is an invasive species that stands out for its aggressiveness, invading pastures, agricultural areas and forests. In order to improve this situation, several techniques have been tested, although not common to tropical climate areas. Thus, the objective of this study was to evaluate the survival of eleven tree species according t

10. Vegetative Propagation of Brazilian Native Species for Restoration of Degraded Areas
ABSTRACT Vegetative propagation by live cuttings is an alternative to reproduce native plants with the potential to be used in restoration of riparian forests and degraded areas. This propagation capacity is intrinsic to each species and is influenced by several factors, particularly the time of the year when cuttings are collected. The aim of this work was

11. Photosynthesis and Growth of Copaiba Seedlings Subjected to Soil Flooding
ABSTRACT The present study aimed to evaluate the effects of soil flooding on photosynthesis, growth, and biomass partitioning of young plants of copaiba (Copaifera lucens Dwyer, Fabaceae ) to investigate the possibility of using this species in restoration projects of riparian forests. Based on our results, we concluded that young plants of C. lucens are ab

12. Vegetative and Environmental Components in a Secondary Riparian Forest in the Southern Plateau of Santa Catarina, Brazil
ABSTRACT This study investigated the vegetation and environmental variable of fragments at different successional stages in a secondary riparian forest in the municipality of Ponte Alta, Santa Catarina state, Brazil (27°29’00” S and 50°17’11” W, WGS84), aiming to list priority variables for monitoring forest succession in riparian forests.
