10. Descrição da estrutura anatômica do lenho e sua aplicação na identificação de espécies arbóreas do cerrado e da Mata Atlântica do Estado de São Paulo. / Description of the anatomical structure of the log and its application in the identification of arboreal species from the cerrado and the mata atlântica of the state of São Paulo.
The bio diversity of Brazil is a subject that is being argued more frequently in the direction of its preservation, conservation and sustainable use. The anatomy of the wood, important branch of Dendrology, is an essential tool for the determination of the floristic composition, since the taxonomic identification is restricted and limited for the difficultie

11. Phylogenetic and Morphological Diversity of Cyanobacteria in Soil Desert Crusts from the Colorado Plateau
We compared the community structures of cyanobacteria in four biological desert crusts from Utah's Colorado Plateau developing on different substrata. We analyzed natural samples, cultures, and cyanobacterial filaments or colonies retrieved by micromanipulation from field samples using microscopy, denaturing gradient gel electrophoresis, and sequencing of 16
