13. Forest Restoration Evaluation Through Indicators in Areas of Bauxite Mining
ABSTRACT The state of Pará ranks second in Brazilian mineral production, where bauxite accounts for 84% of total mineral extraction, with negative impacts on the environment as a result. The determination of objectives and targets using environmental indicators as a tool to evaluate forest restoration processes is essential in the recovery of these exploite

14. Forest Restoration in the State of Rio De Janeiro: Adherence to Legislation
ABSTRACT This study evaluated forest restoration projects filed at the state environmental agency of Rio de Janeiro (Inea), regarding the requirements contained in the Resolution Nº 36/2011. Legal, technical, environmental and ecological parameters of 65 restoration projects in the design and implementation phases were analyzed. Only 29% of the projects met

15. Leaf-litter Entomofauna as a Parameter to Evaluate Areas Under Ecological Restoration
ABSTRACT The aim of this study was to characterize the leaf-litter entomofauna in degraded areas under restoration process with different restoration techniques, using the native forest as a reference and ecological indexes as parameters to select bioindicator groups. The study was conducted at “Serra do Itajaí” National Park (PNSI). The survey was cond

16. Pteridophytes as ecological indicators: an overview
RESUMO As pteridófitas apresentam grande potencial como indicadores ecológicos (EIs), mas pouco explorado, mostrado apenas em trabalhos esparsos. Portanto, para analisar esse potencial, revisamos artigos publicados, sites ou livros com pteridófitas como EIs, realizando buscas em cinco bases de dados acadêmicas e no Google. Selecionamos 134 estudos, feito

18. 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. For thi

19. Phytosociology of the herbaceous-subshrub layer of a rupestrian complex in Serra do Espinhaço, Brazil
ABSTRACT Rupestrian complexes of the Serra do Espinhaço are recognized for their high degree of biodiversity and endemism. However, environmental impacts, particularly from mining, have degraded these environments. The purpose of this study was to describe the herbaceous-subshrub communities that occur in quartzitic (QRC) and ferruginous (FRC) rupestrian co

20. ECOLOGICAL-ECONOMIC ZONING OF THE CITY OF ALTINÓPOLIS – SP, BRAZIL
ABSTRACT: Since colonial times, Brazilian land use has been made under an extractivist model at the expense of deforestation, increasing soil and vegetation depletion, stream siltation, as well as loss of biodiversity. An ecological-economic zoning (EEZ) has been taken as feasible alternative to guide public policies aimed at city land-use planning. This stu

21. Management of the environmental restoration of degraded areas
The aim of this work was to study ecotechnology for the management of degraded areas originally covered by the Atlantic Rainforest and located at the coordinates 25º31'50''S, 9º09'30''W. The area included 12 islands, each consisting of six jute bags with 20 kg of substrate (cattle manure and soil transposed from forest fragments). In six of these bags, nat

22. Retrolabyrinthine approach for cochlear nerve preservation in neurofibromatosis type 2 and simultaneous cochlear implantation
INTRODUCTION: Few cases of cochlear implantation (CI) in neurofibromatosis type 2 (NF2) patients had been reported in the literature. The approaches described were translabyrinthine, retrosigmoid or middle cranial fossa. OBJECTIVES: To describe a case of a NF2- deafened-patient who underwent to vestibular schwannoma resection via RLA with cochlear nerve pres

23. Reproductive biology and early establishment of Pinus elliottii var. elliottii in Brazilian sandy coastal plain vegetation: implications for biological invasion
Pinus is the most invasive woody taxon, exceeded only by herbaceous plants. This study reports the reproductive biology and early establishment of Pinus elliottii Engelm. var. elliottii, describing its invasive properties in a protected natural area of the Brazilian coastal sandy plains. We evaluated the seed germination and rain, longevity of seed viability

24. Structure and floristic pattern of a coastal dunes in southeastern Brazil
The Brazilian shrublands area (restinga) is composed of marine coast vegetation on Quaternary sandy plains, where the species composition can vary depending on the surrounding ecosystems. The aims of this study were to describe the structure and floristic composition of a restinga near the community of Itaúnas, in the northern part of the state of Espírito
