- Abstract: In this study we evaluated floristic composition patterns of communities of climbers within ten inventoriescarried out in semideciduous forest fragments of southeastern Brazil. One of the inventories is original, beingcarried out for the present study in Ribeirão Cachoeira forest, Campinas, São Paulo State, Southeastern Brazil. Thisinventory was then pooled together to other nine climbers’ inventories made in other forests of Southeastern Brazilto form a data base, which was examined regarding species richness, similarity, species distribution and climbingmethods. The total number of species obtained was 355, belonging to 145 genera and 43 families. The ten mostdiverse families Bignoniaceae (45 species), Fabaceae (42), Malpighiaceae (36), Asteraceae (31), Apocynaceae(29), Sapindaceae (28), Convolvulaceae (21), Cucurbitaceae (14), Passifloraceae (10), and Euphorbiaceae (8)contributed to 74.4% of the total number of species recorded. The commonest climbing method in the studied siteswas main stem or branch twining, accounting for 178 species or 50.1% of the total, the second commonest wastendril climbing (121 species, 34.1%), and the least, scrambling (56 species, 15.8%). We found a high percentageof exclusive species i.e., those occurring in only one forest site, which accounted for 49.3% of the total recorded.The mean similarity among forest sites (30%) may be considered low. The climbing species contribution to the totalwood plant richness recorded on the forests sites was very high in some of the sites (up to 52.5%). These resultsindicated the importance of climber communities to plant diversity for semideciduous forests in SoutheasternBrazil, enhancing the regional diversity and the conservation value of these forest remnants.Keywords: lianas, climbing mechanism, floristic, similarity, NMS.

- The goal of this work was to study the species composition, the use of breeding sites, and the seasonal patterns of breeding activity of the anuran fauna from Parque Estadual Carlos Botelho - Nucleo Sete Barras, state of Sao Paulo, southeastern Brazil. Fieldwork was carried out from September 2005 to October 2007 through two main methods: active visual search inside a 10 ha- permanent plot and aural and visual search in seven previously selected aquatic breeding habitats. Species richness was related to the sampling effort by means of species accumulation curve and through non-parametric estimators. Thirty-three species distributed in 12 families were recorded, from which 69% are endemic to the Atlantic Forest. Trachycephalus mesophaeus represents a new record for the park. Cycloramphus lutzorum is included as Data Deficient in the IUCN list. The species accumulation curve did not stabilize, showing some tendency to rise. The use of breeding sites by 20 species was compared using cluster analysis, which revealed two major groups: the first with five species (two habitat generalists and three stream specialists) and the second composed by the other species (with different reproductive modes associated with flooded environments). The breeding period of most species was associated to the rainy season (October to February), and only Scinax hayii showed continuous breeding activity during the entire period of study.
