Resumo

The diversity and richness of bats was analysed between 1991 and 1997 in an regenerated forest at Rio de Janeiro city. The minimum effort of 14,000 hour-nets in 12 or more nights was achieved in each of six sites. The total sampling of bats comprised 4,043 animals, being recognized the occurrence of 40 species. The number of species confirmed by local varied from 19 to 27. The capture efficiency varied from 0.0124 to 0.0473 bat/net-hour. The diversity (Index of Shannon-Wiener) varied from H’ = 1.87 and H’ = 2.19. The comparison of this sampling with similar works carried out in Atlantic Forest at southeastern Brazil demonstrates that: (1) the diversity in the Massif of Tijuca is elevated, comparable with other areas where H’ tended to be 2.0; (2) the richness confirmed in each site is among the highest observed in the Atlantic Forest in southeastern Brazil.
