Acesso restrito. p. 56-61Little is known about the recruitment and behaviour of sponge larvae, especially of the class Calcarea. The calcareous sponge Paraleucilla magna is very common in Southeast Brazil, where it is considered a cryptogenic species. This study quantified recruitment rates in shaded and illuminated habitats for 2 years in Rio de Janeiro, Brazil, and analyzed larval photoresponses of this species. Four structures, each containing a shaded and an illuminated surface, were exchanged every 3 months for 2 years. The number of recruits was quantified on each plate. In the laboratory, larvae of P. magna were placed in halfshaded Petri dishes and the number of settlers in each side was counted after 24 h. Paraleucilla magna recruited continuously throughout the experiment. Recruits occurred in greater abundance on shaded surfaces than on illuminated surfaces, and the larvae were negatively phototactic in vitro. Despite the possible influence of other factors in the recruitment of sponges (such as sedimentation, competition and predation), the prevalence of P. magna in shaded habitats may also be related to larval choice.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-06-26T15:26:49Z No. of bitstreams: 1 111111.pdf: 176789 bytes, checksum: e22e108edb4c04e664dd79f7798d3b9d (MD5)Approved for entry into archive by Alda Lima da Silva(sivalda@ufba.br) on 2013-06-27T21:03:25Z (GMT) No. of bitstreams: 1 111111.pdf: 176789 bytes, checksum: e22e108edb4c04e664dd79f7798d3b9d (MD5)Made available in DSpace on 2013-06-27T21:03:25Z (GMT).
