- ... Toxicity tests were performed exposing the polychaete Dinophilus gyrociliatus to seawater samples containing the toxic dinoflagellate Ostreopsis cf. ovata. Experiments were carried out twice in mid summer, when O. cf. ovata bloomed, and twice in late summer, when the dinoflagellate density declined. Each time, four treatments were considered: original sample; reference sample, which always contain ...

- ... Mating opportunities fluctuate in the wild and hermaphrodites have the chance of partitioning reproductive resources between their two sexual functions accordingly, i.e., they have a plastic sex allocation. Plasticity is usually promoted by environmental fluctuations but may be affected by species-specific factors, which may be revealed by comparisons between related species. We tested whether pol ...

- ... The effects of diet and density on growth, survival and gametogenesis of the common ragworm Hediste diversicolor (Nereididae, Polychaeta) were investigated with the aim of contributing to define their optimal ranges in the context of a commercial farming system. Two different experimental trials were set up: in the first one, juveniles of H. diversicolor, obtained from laboratory cultures establis ...
