Ascídias (Tunicata, Ascidiacea) introduzidas no Arquipélago de Alcatrazes, São Paulo

Abstract: O Arquipélago de Alcatrazes (24º06'S, 45º42'W) localiza-se a 36 km da costa e constitui uma Estação Ecológica desde 1987. Estando próximo à região portuária de São Sebastião, São Paulo, está sujeito à introdução de espécies exóticas. Com o objetivo de detectar se está ocorrendo ou não introdução de espécies, foram coletados 40 exemplares de ascídias da principal ilha do arquipélago, a Ilha de Alcatrazes, sendo 15 amostras da Baía do Oratório e 25 do Saco do Funil. Foram encontradas 24 espécies em sete famílias… Show more

“…Modular growth, fragmentation and fission of colonies are part of the life-cycle of the encrusting ascidian Didemnum rodriguesi Rocha & Monniot, 1993 which is relatively common in sublitoral rocky substrates of southeastern (ROCHA & BONNET, 2009) and southern Brazil (ROCHA et al, 2005). Here we studied reproductive strategies of D. rodriguesi in terms of investment in sexual and asexual reproduction and their associations with mortality and fusion rates to test for the relative importance and consequences of each mode of reproduction.…”
