Small core communities and high variability in bacteria associated with the introduced ascidian Styela plicata
The solitary ascidian Styela plicata is an introduced species in harbors of temperate and tropical oceans around the world. The invasive potential of this species has been studied through reproductive biology and population genetics but no study has yet examined the microbial diversity associated with this ascidian and its potential role in host ecology and [...]

Relatively little is known about the life cycles of ascidians in temperate seas. Here, we investigated the biological cycle of the colonial ascidian Didemnum fulgens, a dominan species in some shallow localities of the NW Mediterranean Sea. Growth rates and frequencies of fission/fusion events were calculated over a period of 13 months, and th reproductive cycle determined after [...]

L’activité de nettoyage de Lepadogaster candolii Risso, 1810 a été observée pour la première fois en août 2009, au cours d’une plongée réalisée dans la Réserve Marine des Îles Medes (Méditerranée nord-occidentale). L’individu nettoyait la cavité buccale d’un grand mérou Epinephelus marginatus (Lowe, 1834), qui restait bouche ouverte et immobile à quelque distance du [...]

Pérez-Portela, R., Almada, V. & Turon, X. . Cryptic speciation and genetic structure of widely distributed brittle stars (Ophiuroidea) in Europe. Zoologica Scripta 42 : 151–169 (2013) The development of molecular techniques has led to the detection of numerous cases of cryptic speciation within widely distributed marine invertebrate species and important taxonomic revisions in all the major marine [...]
