13. Radiossensibilidade gama de Cladonia substellata Vainio (lÃquen) e o conseqÃente efeito sobre rochas calcÃrias / Gamma radiosensibility of Cladonia substellata vainio (lichen) and the consequent chelating effect on calcareous rocks
Soil is an unconsolidated surface that recovers the rocks and maintains animal and plant life on Earth. It is formed from climatic and biotic relationship, modified by topography that acts on original material, over a long period of time. Concerning biotic activities, one may emphasize that performed by lichens, which allow the succession of rocky substratum

14. Dinâmica da regeneração natural de espécies arbóreas e arbustivas no sub-bosque de povoamento de Mimosa scabrella Bentham, em área minerada, em Poços de Caldas-MG / Dynamics of natural regeneration of tree and shrub community in understory of stands of Mimosa scabrella Bentham in mined area, Poços de Caldas, Brazil
In 1982/1983 as part of its mine rehabilitation strategy, ALCOA Alumínio S.A. hydroseeded herbaceous species and planted tree seedlings of Mimosa scabrella Bentham in Retiro-Branco bauxite mining site. In 1997, 19 sample plots of 50m2 were implanted in this area for initial characterization of natural regeneration process. Sampling sufficiency and ideal siz

15. 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

16. Molecular Basis of Symbiotic Promiscuity
Eukaryotes often form symbioses with microorganisms. Among these, associations between plants and nitrogen-fixing bacteria are responsible for the nitrogen input into various ecological niches. Plants of many different families have evolved the capacity to develop root or stem nodules with diverse genera of soil bacteria. Of these, symbioses between legumes
