Occurrence and distribution of <I>Bostrychia</I> and <I>Caloglossa</I> (Rhodophyta, Ceramiales) in the Ratones River Mangrove, Florianópolis - SC- Brazil

Abstract

Four species of Bostrychia and two of Caloglossa were identified and their horizontal and vertical distribution are described for Santa Catarina State of Brazil. The reproductive state of each taxa along the year is also given. Horizontal and vertical distributions, and seasonal occurrence of fertile plants of Bostrychia and Caloglossa spp. are given for the seven identified taxa. Bostrychia radicans was more abundant at the river mouth (site one), where salinity ranged from 20 to 36%¢. Site two, located 1.7 km from the river mouth, with salinity varying from 12 to 30%¢ exhibited the largest specific diversity. Caloglossa leprieurii was more abundant upstream in areas with lower salinity.
