Abstract The Humboldt Current System (HCS) is one of the most productive marine
ecosystems on earth. It extends along the west coast of South America from southern Chile …

Methodological and biological considerations are intertwined when studying cryptic species.
A potentially large component of modern biodiversity, the frequency of cryptic species …

Reflecting increased interest in the field and its relevance in global environmental issues,
Oceanography and Marine Biology: An Annual Review, Volume 45 provides authoritative …

A previous molecular study has revealed that the Mediterranean reef building vermetid
gastropod Dendropoma petraeum conforms a complex of at least four cryptic species with …

Evolutionary transitions between different modes of development in marine invertebrates are
thought to be biased toward the loss of feeding larvae. Because the morphology of feeding …

Current knowledge about the performance of floating seaweeds as dispersal vectors comes
mostly from mid latitudes (30°–40°), but phylogeographic studies suggest that long-distance …

Calyptraeid gastropods are well know for the taxonomic difficulties caused by their simple,
phenotypically variable shells. In this paper I demonstrate that what was previously …

Intracapsular development is common in marine gastropods. In many species, embryos
develop alongside nurse eggs, which provide nutrition during ontogeny. The common whelk …

In gregarious species with copulation and internal fertilization, male–male competition and
female cryptic choice may affect reproductive success of both sexes. We carried out a …

Abstract A new Pliocene (3.4 Ma) mollusk fauna from Mejillones Peninsula, northern Chile is
described and compared with the Pliocene La Cueva fauna of little constrained age from …
