Última Vertical structure of an assemblage of bats (Mammalia: Chiroptera) in a fragment of Atlantic Forest in Southern Brazil Rev. Bras. Zool. Carvalho,Fernando; Fabián,Marta E.; Menegheti,João O.. Few studies have focused the vertical structure of bat assemblages, and how it influences community composition. The goal of this study was to analyze the vertical structure of an assemblage of bats in a forest fragment in southern Brazil. Bats were sampled using mist-nets placed at three heights (understory, below-canopy, and canopy). Forest strata were compared with respect to their species richness and diversity. The latter was estimated using the Shannon-Wiener index (H'), and the statistical significance of differences among strata was assessed using t tests. We used an index of Constancy (C) to determine the frequency of a given species in each vegetation stratum, such that a species was considered as "frequent" (C > 50), "less frequent" (25...

A detailed analysis of the interactions between Tursiops truncatus (Montagu, 1821) and the artisanal fishing of mullets (Mugil spp.) is presented at two localities in the south of Brazil: Laguna (Santa Catarina) and Inibé/Tramandaí (Rio Grande do Sul). Its behavioral strategies and the advantages of their association are re-described and quantified based on the success of the capture and on the selectivity of the prey sizes. The mullets are the main resource involved (92% to 75%) both at numerical level and as biomass. Twenty individuals of Tursiops truncatus participated in the interactions in Laguna and 9 in Imbé/Tramandaí. The participation and learning of calves is also reported.
