Biodiversity of the Mediterranean Sea: estimates, patterns and threats
Marta Coll,Jacopo Aguzzi,Enric Ballesteros,Marta Estrada,Josep M. Gasol,João Gil,Daniel Martin,Daniel Oro,José Templado,Xavier Turon,Roger Villanueva,Eleni Voultsiadou +11 more
TL;DR: Overall spatial and temporal patterns of species diversity and major changes and threats were assessed, and temporal trends indicated that overexploitation and habitat loss have been the main human drivers of historical changes in biodiversity.

TL;DR: In this article, the authors combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists.
Journal ArticleDOI
Lipid and fatty acid composition of early stages of cephalopods : an approach to their lipid requirements
TL;DR: It can be deduced that cephalopod paralarvae and juveniles must require a food rich in polyunsaturated fatty acids (PUFA), phospholipids and cholesterol and with a moderate content in neutral lipids.
Journal ArticleDOI
Rearing of Octopus vulgaris paralarvae: Present status, bottlenecks and trends
Jorge Iglesias,F. J. Sánchez,J.G.F. Bersano,José Francisco Carrasco,Jean Dhont,Lidia Fuentes,F. Linares,Jose Luis Muñoz,S. Okumura,Javier Roo,T. Van Der Meeren,Erica A. G. Vidal,Roger Villanueva +12 more
TL;DR: Rearing techniques for the O. vulgaris paralarvae used by the different research participant teams are described, with regard to tank systems, feeding environment, and diets (Artemia, crustacean zoeae, sandeel flakes, copepods, etc.).
Journal ArticleDOI
Experimental rearing and growth of planktonic Octopus vulgaris from hatching to settlement
TL;DR: Comparison of these results with previous studies suggests that paralarvae settle when they reach a critical size irrespective of age, and that the duration of the planktonic period is probably temperature dependent.
