Critérios para a amostragem de lianas: comparação e estimativa da abundância e biomassa de lianas no Cerrado

Lianas play a key role in many tropical forests ecosystems, contributing to community abundance, diversity and structure. Techniques to census lianas and estimate biomass have been used mainly in tropical forests. The aim of this study was to verify if different measurement location on the stem and inclusion criteria influence the estimations of liana abundance and biomass in Cerrado. The study was carried out at Itirapina fragment (ca 260 ha) located in Sao Paulo, Southeast Brazil. We measured all apparent ramets of rooted lianas by using different inclusion criteria: >= 0.5 cm in diameter at 30 cm basal area (D_30), and at 130 cm diameter breast height (DBH), in 36 transects (10 x 25 m). We compared the biomass using the allometric equation based on data from tropical florest take at 130 cm (DBH) and other The allometric biomass equation development to estimate the aboveground biomass of live lianas in tropical forests (DAP = 130 cm) was used. We tested the liana biomass, based on measurements taken at (D_30) using two different conversion equations. The results did not show significant differences in liana abundance and above ground biomass estimated applying the different criteria of inclusion However the biomass estimated from data collected at D_30 and converted into DAP showed a tendency to increase in biomass. Our findings suggest that the protocol used to the census of liana and the allometric biomass equation proposed to forests can be applied in the Cerrado.

Potenciais aves dispersoras de sementes das espécies vegetais zoocóricas da Mata da Bica, Botucatu - SP

The semidecidual forests, as tropical forests, presents zoochoric dispersal syndrome in the most of their plant species, with approximately one third of frugivorous species responsible for the seeds dispersal are birds. The bills width is a limiting factor, it must be equal or bigger than the seeds width, because the viable seeds dispersal depends on leaving the digestive system after been swallowed hole. Birds and plants inventorys were realized in a semidecidual Forest fragment, in Botucatu – SP, called Mata da Bica. After this, the birds consumers of fuits/seeds were selected (frugivorous, granivorous and onivorous) and also the zoochoric plants, both for building a possibilities matrix, to verify the potential seed dispersers according to the seeds and bills width. Going to the matrix end we can observe a decrease in the interaction possibillities, because the seeds width increases and the bills width decreases. It has been observed that 50,7% seeds could be dispersed by all listed birds, because the seeds were narrower than the narrowest bill. In the other way large seeded species, as Holocalix balansae and Hymemaea courbaril has shown only two possible dispersers: Trogon surrucura and Piaya cayana. There are no possible dispersers to Syagrus oleraceae in the matrix. The need for large birds or other animals that works as large seed disperses demand conservation efforts, since most of these animals need big and conserved areas for their life habits
