Diversidade de Formicidae (Hymenoptera) em um fragmento de Floresta Estacional Semidecídua no Noroeste do Estado de São Paulo, Brasil.

(Ant diversity (Hymenoptera) in a fragment of Semidecidual Seasonal Forest in Northwest of São Paulo State, Brazil). Due to scarce knowledge about ant fauna from Northwestern São Paulo State, the present study aimed to know the taxonomic diversity of Formicidae, relating the results to climatic variation along of one year. The samples were gotten monthly, using pitfall traps. It was sampled 25 species of 15 genera and seven subfamilies. Myrmicinae was the sampled richest subfamily, follows by Formicinae and Ponerinae. According Wilcoxon test, the species richness, equability and diversity estimated by Simpson index were significantly higher in the rain season. The obtained results suggest that the abundance of ants is significantly related to the temperature variation, while the ant assemblage structure is related to thermal and pluviometric variations.

Regeneração natural do componente arbóreo após a mortalidade de um maciço de taquara em um fragmento de floresta ombrófila mista em Lages - SC

The present study aimed to analyze the floristic and structural descriptors of tree species natural regeneration in a forest sector with synchronized bamboo (Merostachys multiramea Hackel) die-off (CT) and an adjacent area with continuous canopy cover (ST) in an araucaria forest fragment in the municipality of Lages, Santa Catarina state. A total of 14, 5x5m, plots (six plots in CT sector and eight in ST sector) were allocated, where all tree species regenerative individual with circumference at breast height smaller than 15cm and height higher than 25cm was measured (diameter at soil level) and identified. The richest families were: Myrtaceae (nine), Solanaceae (six) and Aquifoliaceae (four). The Shannon Diversity Index in ST and CT sectors were respectively 2.73 and 2.31. The species with the highest importance values in CT sector were Solanum variabile, Piptocarpha angustifolia, Mimosa scabrella, Jacaranda puberula and Solanum pseudoquina. In ST sector, the species with highest importance values were Myrsine lorentziana, Casearia decandra, Cinnamodendron dinisii, Drimys brasiliensis and Ilex paraguariensis. The results showed that the synchronized bamboo die-off influenced the spatial variation in the floristic and structural descriptors of the tree species natural regeneration.

Regeneração natural de mata ciliar em ecossistema de floresta estacional semidecidual: chuva de sementes e banco de sementes do solo

The knowledge of the dynamics of soil seed bank and seed rain is fundamental to understand the forest succession process, as well as for its conservation and restoration. This paper aimed at studying the role of the soil seed bank and seed rain in the dynamics of a riparian tropical seasonal forest fragment located on the hinterland of São Paulo State. The seed rain was studied by 30 litter traps installed at 50 cm from the floor, with an area of 50 cm x 50 cm. Between November of 2008 and October of 2009, 11364 seeds of 82 species belonging to 33 different families were collected. The deposition density of seeds was 126.27 individuals.m². With the data obtained from this research, the two seasons couldn’t be differed from each other hence 2009 was an atypical year considering the precipitation, which was constantly elevated. For the soil seed bank, fifty superficial soil samples will be taken at the end of both the rainy and dry seasons. The germination method was applied for the data analysis. It was observed a predominance of herbaceous habit species, with an average of 71% of the germinations in both seasons. The Sφrensen similarity index between the seasons was low (0,27). The density and species diversity were higher after the rainy season, unlike other published researches
