BACKGROUND The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered.

BACKGROUND Biogeographical and macroecological principles are derived from patterns of distribution in large organisms, whereas microscopic ones have often been considered uninteresting, because of their supposed wide distribution. Here, after reporting the results of an intensive faunistic survey of marine microscopic animals (meiofauna) in Northern(More)
Monocelis lineata consists of a complex of sibling species, widespread in the Mediterranean and Atlantic Ocean. Previous genetic analysis placed in evidence at least four sibling species. Nevertheless, this research was not conclusive enough to fully resolve the complex or to infer the phylogeny/phylogeography of the group. We designed specific primers(More)
Pinna nobilis is the largest endemic Mediterranean marine bivalve. During past centuries, various human activities have promoted the regression of its populations. As a consequence of stringent standards of protection, demographic expansions are currently reported in many sites. The aim of this study was to provide the first large broad-scale insight into(More)
The order Proseriata (Platyhelminthes) represents one of the most abundant soft-bodied meiofaunal groups. These minute interstitial organisms are characterized by a very simple morphology, which often hides the occurrence of cryptic species. Accordingly, molecular analyses are often needed to provide reliable taxonomic assessment and/or species(More)
Patterns of genetic variation in marine species reflect the interplay of species-specific traits, oceanographic features, historical processes and selection. In the Atlantic–Mediterranean regions, Patella ulyssiponensis (Mollusca: Gastropoda) was previously used as a model to investigate these patterns. Our study gained insight into the genetic patterns of(More)
The composition of the taxon Proseriata (Platyhelminthes) in the São Sebastião area (S.E. Brazil) is presented and discussed. The area was extensively studied by E. Marcus, who described a large number of species, most of which have not been found thereafter. Of the 29 species found, 16 have been described by Marcus. The new findings allowed in many cases(More)
