A pioneering longterm experiment on mesophotic macrofouling communities in the North Atlantic.

The mesophotic zone represents one of our planet's largest and least explored biomes. An increasing number of studies evidence the importance of macrofouling species in marine ecosystems, but information on these communities and the factors influencing their structures at mesophotic depths remain poor. This lack of understanding limits our ability to predict anthropogenic impacts or conduct restoration operations in the mesophotic and the lower boundary of the euphotic zones.

Non-indigenous species of Bryozoa from anthropogenic habitats in the Bay of Cádiz (South Iberian Peninsula).

Samples of bryozoans collected from two localities in the Bay of Cádiz with different levels of anthropogenic impact are studied. A total of 25 species was identified, of which 8 are considered non-indigenous (NIS), 12 as native and 5 cryptogenic. A new species of , sp.

Multiple evolutionary transitions of reproductive strategies in a phylum of aquatic colonial invertebrates.

Parental care is considered crucial for the enhanced survival of offspring and evolutionary success of many metazoan groups. Most bryozoans incubate their young in brood chambers or intracoelomically. Based on the drastic morphological differences in incubation chambers across members of the order Cheilostomatida (class Gymnolaemata), multiple origins of incubation were predicted in this group.

New species and new records of bryozoan species from fouling communities in the Madeira Archipelago (NE Atlantic).

Hull fouling is considered to be the most significant vector of introduction of marine non-indigenous species (NIS) in the Madeira Archipelago (NE Atlantic) because these islands provide a vital passage route for many ships. The transfer of species between boat hulls and artificial substrates in marinas is known to be high. Bryozoans are among the most common groups of marine invertebrates growing on this type of substrate.

Bryozoan diversity on a whale bone: an uncommon substrate from the continental shelf off NW Spain.

Unlabelled: Carcasses and bones of whales are interesting yet poorly understood habitats for invertebrates and microbial communities. Nevertheless, bryozoans have never before been reported in this particular habitat at the present day. Here, we present the first study on a bryozoan community colonizing a whale bone from the continental shelf off NW Spain at 128 m depth.

Watersiporidae (Bryozoa) in Iberian waters: an update on alien and native species.

Species of the genus comprise an important invasive fouling group but are difficult to identify up to species level. This problem, in conjunction with the recent re-description of several member species, requires the revision of previous records and newly collected material in order to more precisely determine their actual presence and distribution. Here, we revise the identity and distribution of alien and native species of Watersiporidae in Iberian waters based on newly collected material, historical collections, and bibliographic data.

New species and new records of bryozoans from Galicia (NW Spain).

Although the bryozoological fauna of Galicia (NW Spain) is probably the best known of the whole Iberian Peninsula, and perhaps one of the better known in Europe, new studies continue to provide new knowledge. A new species, sp. nov.

Dismantling the (Busk, 1852) species complex (Bryozoa, Cheilostomata): two new species from European waters.

New research on bryozoans has determined that formerly widespread species are in many cases complexes of similar, but distinct, species with more restricted distributions. Notwithstanding, the limits of distribution are still unresolved for many taxa, and occasionally a wide distribution is confirmed. has been considered a widespread species, distributed throughout the Southern Hemisphere, parts of northern Pacific and Atlantic Oceans and the Mediterranean Sea.

Methodology to Reduce Distortion Using a Hybrid Thermal Welding Process.

Welding is a thermal process which results in high strain and stress values in the material and leads to its change of phase. This might cause significant distortions in the welded structure, which often becomes a relevant design and manufacturing issue. This study deals with a line-heating-based forming process that is applied at the moment of the welding operation, with the final objective of minimizing distortion.

Systematics and diversity of deep-water Cheilostomata (Bryozoa) from Galicia Bank (NE Atlantic).

Galicia Bank is a large seamount situated c. 200 km off NW Iberia with a minimum depth of 600 m. It was recently included in Natura 2000, an EU-wide network of nature protection areas.

Diversity and Systematics of Schizomavella Species (Bryozoa: Bitectiporidae) from the Bathyal NE Atlantic.

Eight NE Atlantic and Mediterranean species, which were originally assigned to the genus Schizoporella (Family Schizoporellidae) when introduced, are redescribed and stabilized by typification. Seven of these species are transferred to the bitectiporid genus Schizomavella: S. fischeri, S.

New species and new records of bryozoans from shallow waters of Madeira Island.

Two new species of bryozoans encrusting subtidal rocks are described from the shallow waters of Madeira Island. We describe one cyclostome, Favosipora purpurea sp. nov.

New species of Bryozoa from Madeira associated with rhodoliths.

Four new species of cheilostomate Bryozoa encrusting rhodoliths on Maërl beds are described from material collected at a single locality at Madeira Island. These are Coronellina atlantica n. sp.
