Fossil age data and molecular sequences are increasingly combined to establish a
timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically …

Barnacles are intriguing, not only with respect to their importance as fouling organisms, but
also in terms of the mechanism of underwater adhesion, which provides a platform for …

We present a comprehensive revision and synthesis of the higher-level classification of the
barnacles (Crustacea: Thecostraca) to the genus level and including both extant and fossils …

Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977,
numerous vent sites and endemic faunal assemblages have been found along mid-ocean …

Some marine invertebrates can inhabit floating substrates, and raft over long distances,
becoming a significant environmental problem in terms of alien species and habitat …

The characterization of evolutionary and biogeographical patterns is of fundamental
importance to identify factors driving biodiversity. Due to their widespread but discontinuous …

The Helicoidea is one of the most diverse superfamilies of terrestrial land snails. In this study
we present a molecular phylogeny of the western Palaearctic Helicoidea obtained by means …

Dioecy (gonochorism) is dominant within the Animalia, although a recent review suggests
hermaphroditism is also common. Evolutionary transitions from dioecy to hermaphroditism …

Though not directly dependent on photosynthesis, deep-sea chemosynthetic communities
have not been sheltered from catastrophic changes affecting Earth's photic zone. Instead …

Rhizocephalans are abundant members of marine ecosystems and are important regulators
of crustacean host populations. Morphological and ecological variation makes them an …
