1. Lianas of Seasonally Dry Forest: Ecophysiology and Use in Restoration Ecology / Lianas da floresta estacional semidecidual: ecofisiologia e uso em restauração ecológica
Lianas are important components of the structure and dynamics in seasonally dry forests, but there are few studies on their ecophysiology and use in restoration ecology. The objective of this study was to evaluate the ecophysiology of seeds and juveniles of species of liana in the preferences for environmental regeneration and the variables involved in using

3. Germination and emergence of weeds in function of light and the sugarcane (Saccharum spp) harvest residue / Germinação e emergência de plantas daninhas em função da luz e da palha de cana-de-açúcar (Saccharum spp)
During the last years it has been observed an increase in the mechanical harvest without using fire of the sugar cane. This system has been modifying the characteristics of sugar cane, considering that leaves a straw harvest residue on the soil, which affects the light incidence on it and the occurrence and management of weeds. The present experiment was car

4. Bancos de sementes do solo da reserva biologica e estação experimental de Moji Guaçu, em area de cerrado no estado de São Paulo
In spite of have been initially considered an exceptional condition, sexual reproduction of cerrado plants is now accepted as a common fact, as mentioned by several authors working in field and laboratory conditions. Nevertheless, the composition and dynamics of cerrado soil seed banks remain to be understood. This study intends to investigate the soil seed

5. Germinação, crescimento, atividade fotossintetica e translocação de compostos de carbono em especies arboreas tropicais : estudo comparativo e influencia de sombreamento natural
Gennination, growth, photosynthesis and translocation of carbon in tropical tree species: a comparative study and the influence of natural shade. Light has been recognized as a major factor in species replacement during secondary sucession in forests. The degree of shade tolerance may be important in detennining successional sequences, since these are condit
