1. Rhizobial characterization in revegetated areas after bauxite mining
Abstract Little is known regarding how the increased diversity of nitrogen-fixing bacteria contributes to the productivity and diversity of plants in complex communities. However, some authors have shown that the presence of a diverse group of nodulating bacteria is required for different plant species to coexist. A better understanding of the plant symbioti

2. Vegetação dunar: caracterização estrutural de dunas do município de Natal-RN como subsídio para implantação de técnicas de reflorestamernto, recuperação e conservação do ecossistema
The Brazilian coast has a wide variety of complex environments and ecosystems along the coast, about 80% are represented by sandbanks and dunes. The coastal ecosystems were the first to suffer the impacts man and places, as the very fragile ecosystems, are somehow altered. Are few areas of restinga well as natural features, very few protected in conservation

3. Malaise traps for use as strategy for evaluation of bioindicators in agroecosystem : diversity and guild of braconidae in different vegetation mosaics of Fazenda Canchim (Embrapa, São Carlos, Brazil) / Uso de armadilhas Malaise como estratégia de avaliação de bioindicadores em agroecossistemas : diversidade e guildas de Braconidae em diferentes mosaicos vegetacionais da Fazenda Canchim (Embrapa), São Carlos, SP, Brasil
This work aimed to study the composition and distribution of the fauna of Braconidae (Hymenoptera) in three ecosystems of Fazenda Canchim (Embrapa, Sao Carlos, Brazil), analyse the bioindicator potential of that group and its possible use by farmers in order to contribute for the use of a more sustainable agroecosystems. The specimens were captured by three

5. Characterization of organic matter as support to the study of the formation of surface horizon in soils under minimum cultivation of eucalyptus. / CaracterizaÃÃo da matÃria orgÃnica como subsÃdio ao estudo da formaÃÃo de horizonte superficial em solos sob cultivo mÃnimo de eucalipto.
In Brazil, a substantial part of the forest plantations has been undertaken in areas in which the soil presents some degree of physical, chemical or biological degradation. The protection provided by tree canopy of forest plantations and soil cover, as a function of the deposition of litter, is one of the most important processes in the recovery of degraded

6. CRESCIMENTO, ESTADO NUTRICIONAL E CARACTERÍSTICAS FOTOSSINTÉTICAS DE Bertholletia excelsa SOB TRATAMENTOS DE ADUBAÇÃO EM ÁREA DEGRADADA NA AMAZÔNIA CENTRAL
Human activities on forest ecosystems can result in the removal of forest cover followed by impoverishment of the soil physical, chemical and biological properties. Throughout time, these areas without forest coverage can turn in to degraded areas. In face of this, for the revegetation of these areas with forest species different methods have been applied fo

7. Ãreas degradadas do bioma caatinga na regiÃo de Xingo, Brasil: processo de formaÃÃo x recuperaÃÃo ambiental
Os ecossistemas sofrem alteraÃÃes por diferentes agentes de degradaÃÃo, sobretudo pela pressÃo antrÃpica, sendo muitas vezes necessÃria a intervenÃÃo humana para a sua recuperaÃÃo. Foram desenvolvidas vÃrias tÃcnicas de restauraÃÃo para os Biomas brasileiros, porÃm pouco se sabe sobre este processo na Caatinga. Desta forma, este estudo objeti

8. Management of Indigenous Plant-Microbe Symbioses Aids Restoration of Desertified Ecosystems
Disturbance of natural plant communities is the first visible indication of a desertification process, but damage to physical, chemical, and biological soil properties is known to occur simultaneously. Such soil degradation limits reestablishment of the natural plant cover. In particular, desertification causes disturbance of plant-microbe symbioses which ar
