1. Response of mangrove plant species to a saline gradient: Implications for ecological restoration
ABSTRACT Mangroves are salt tolerant plants that occur in tropical and sub-tropical sheltered coasts. Saltwater intrusions into terrestrial landscapes often occur due to either anthropogenic reasons or natural calamities such as tsunamis. We investigated the potential of using mangrove species for rehabilitation of high saline environments by revealing the c

2. Evaluation of environmental rehabilitation practices in bauxite mining at the plateau of Poços de Caldas
Abstract Bauxite mining has been carried out around Poços de Caldas, Minas Gerais, since the 1940s. Companies operating in the region pioneered land rehabilitation in Brazil, conducted since the early 1980s. Different procedures of recontouring, runoff drainage, soil preparation and vegetation planting were employed. This research aims to evaluate current e

4. Deficiência de macronutrientes em Cariniana estrellensis (Raddi) Kintze
Resumo O conhecimento dos efeitos da nutrição mineral sobre a fisiologia vegetal de espécies nativas é um importante auxílio para que se obtenha o sucesso desejado quando estas são usadas no reflorestamento ou na recuperação de áreas degradadas. A presente pesquisa avaliou as consequências da deficiência de macronutrientes em Cariniana estrellensi

5. Diversity and Efficiency of Rhizobia Communities from Iron Mining Areas Using Cowpea as a Trap Plant
ABSTRACT Mining is an important economic activity. However, its impact on environment must be accessed, mainly on relevant processes for their sustainability. The objective of this study was to evaluate the diversity and efficiency of symbiotic nitrogen fixing bacterial communities in soils under different types of vegetation in the Quadrilátero Ferrífero:

6. Enrichment of arbuscular mycorrhizal fungi in a contaminated soil after rehabilitation
Abstract Spore counts, species composition and richness of arbuscular mycorrhizal fungi, and soil glomalin contents were evaluated in a soil contaminated with Zn, Cu, Cd and Pb after rehabilitation by partial replacement of the contaminated soil with non-contaminated soil, and by Eucalyptus camaldulensis planting with and without Brachiaria decumbens sowing.

7. Litter Decomposition of Two Pioneer Tree Species and Associated Soil Fauna in Areas Reclaimed after Surface Coal Mining in Southern Brazil
ABSTRACT Decomposition of leaf litter from pioneer tree species and development of associated soil meso- and macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim of our study was to evaluate decomposition of Schinus terebinthifolius and Senna multijuga to answer three basic questions: (i) What type of leaf litter de

8. Bioindicadores de qualidade do solo em um gradiente de restauração ambiental / Soil quality bioindicators of an environmental restoration gradient
Impactos ambientais podem interferir nas características da biomassa microbiana, no processo de ciclagem de nutrientes, nas características físicoquímicas e também na diversidade da microbiota e da macrofauna. O objetivo desse trabalho foi conhecer as diferentes interações entre estes atributos e identificar os indicadores da qualidade do solo envolvi

9. Espécies tropicais de pteridófitas em associação com fungos micorrízicos arbusculares em solo contaminado com arsênio
The symbiosis of plants with mycorrhizal fungi represents an alternative to be considered during the processes of revegetation and rehabilitation of arsenic-contaminated soil. The aim of this study was to evaluate under greenhouse conditions the effect of arsenic on the mycorrhizal association of two species of tropical fern (Thelypteris salzmannii and Dicra

11. Crescimento e teor de metais de muda de especies arboreas cultivadas em solo contaminado com metais pesados.
O objetivo do trabalho foi avaliar o teor de metais pesados e o crescimento de mudas de 20 especies arboreas tropicais em solo em elevado grau de contaminacao com metais pesados. Em casa de vegetacao, as mudas foram transplantadas para vasos contendo 3,3 kg de misturas com diferentes proporcoes (0, 20, 40 e 60% v/v) de solo contaminado. Verificou-se comporta

12. Diversidade de fungos micorrízicos arbusculares em áreas restauradas de Mata Atlântica, São Paulo, Brasil / Diversity of arbuscular mycorrhizal fungi in restored areas of the Atlantic Forest, São Paulo, Brazil
Os fungos micorrízicos arbusculares (FMA) são muito importantes para a nutrição mineral das plantas e para a recuperação de áreas degradadas, pois possibilitam um melhor desenvolvimento das espécies arbóreas usadas na revegetação. Entretanto, para um melhor desempenho dos FMA, as condições ambientais devem ser favoráveis, pois tanto a ocorrênc
