Growth, size class frequency and reproduction of purple sea urchin, Paracentrotus lividus (Lamarck, 1816) in Bistrina Bay (Adriatic Sea, Croatia)
2002). As a consequence, echinoid stocks had to be strictly managed in order to be protected (LESSER & WALKER, 1998; YOKOTA et al., 2002). Increasing demand for sea urchin roe has led, in the last decade, to over-fishing of natural populations (CONAND & SLOAN, 1989; LE GALL, 1990). Several possible solutions have been tested; reseeding natural habitats with farmed juveniles (AGATSUMA & MOMMA, 1...

متن کاملHigh-quality RNA extraction from the sea urchin Paracentrotus lividus embryos
The sea urchin Paracentrotus lividus (Lamarck, 1816) is a keystone herbivore in the Mediterranean Sea due to its ability to transform macroalgal-dominated communities into barren areas characterized by increased cover of bare substrates and encrusting coralline algae, reduced biodiversity and altered ecosystem functions. P. lividus is also an excellent animal model for toxicology, physiology an...
متن کاملHabitat and Scale Shape the Demographic Fate of the Keystone Sea Urchin Paracentrotus lividus in Mediterranean Macrophyte Communities
Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and spatial scales, this can influence our ability to predict their population at a particular life-history stage given the previous life stage. In particular, when keystone species are involved, this relative coupling between demographic stages can have significant implicatio...
