“…For example, Nemertesia ramosa has large population sizes both in shallow and deep waters, and develops robust ramified colonies from which several reproductive structures can originate, favouring genetic connections across wide bathymetrical ranges. Inversely, demonstrating the correlation between hydroid growth and food availability (Di Camillo et al, ), “true” Nemertesia antennina develops prominent colonies in shallow waters only, leading to wide dispersal of haplotypes throughout the NE Atlantic and Mediterranean, whereas cryptic Nemertesia “ antennina ” has delicate colonies with few reproductive structures in deep waters, resulting in reduced geographic ranges of haplotypes and ultimately sympatric and parapatric speciation. The vulnerability or adaptability of species to thrive in different biotic and abiotic conditions, therefore, seems to affect population sizes and dispersal.…”

We provide preliminary insights into the global phylogeographic and evolutionary patterns across species of the hydrozoan superfamily Plumularioidea (Cnidaria: Hydrozoa). We analyzed 1,114 16S sequences of 198 putative species of Plumularioidea collected worldwide. We investigated genetic connections and divergence in relation to present‐day and ancient biogeographic barriers, climate changes and oceanic circulation. Geographical distributions of most species are generally more constrained than previously assumed. Some species able to raft are dispersed widely. Human‐mediated dispersal explains some wide geographical ranges. Trans‐Atlantic genetic connections are presently unlikely for most of the tropical‐temperate species, but were probably more frequent until the Miocene–Pliocene transition, before restriction of the Tethys Sea and the Central American Seaway. Trans‐Atlantic colonizations were predominantly directed westwards through (sub)tropical waters. The Azores were colonized multiple times and through different routes, mainly from the east Atlantic, at least since the Pliocene. Extant geminate clades separated by the Isthmus of Panama have predominantly Atlantic origin. Various ancient colonizations mainly directed from the Indian Ocean to the Atlantic occurred through the Tethys Sea and around South Africa in periods of lower intensity of the Benguela upwelling. Thermal tolerance, population sizes, dispersal strategies, oceanic currents, substrate preference, and land barriers are important factors for dispersal and speciation of marine hydroids.

“…Hydrozoans were a minor contributor to the communities detected at Burdwood Bank. Di Camillo et al (2017) demonstrated the role of these as habitat-forming organisms for small fauna and the juvenile stages of many organisms. The complex threedimensional structures developed by the hydrozoan species recorded during this study hosted several associates, principally other small hydroid colonies, thus providing microhabitats for small organisms, and in this way increasing the general richness of the habitat at the slope (Martin Sirito, 2019 hydroids were considered epizoic generalists that settle principally on living substrata (Genzano et al, 2017;Genzano, Giberto, Schejter, Bremec, & Meretta, 2009).…”

“…In the North Atlantic, sponge grounds occur on gravel and coarse sand bottoms from 150 to 1700 m in depth, reaching densities of 5-25 sponges per m 2 , also increasing the number of associated fauna (Beazley, Kenchington, Murillo, & Sacau, 2013;Knudby, Kenchington, & Murillo, 2013). Hydroids, at their relative dimensional scale, also change the features of the geological habitat, becoming habitat formers by providing settling space, shelter, or food to several associated species, thereby enhancing local biodiversity (Di Camillo et al, 2017). Moreover, hydroid forests release a large number of planulae, medusoids, or medusae into the surrounding environment, contributing to benthic-pelagic coupling and affecting biogeochemical cycles (Gili et al, 1998;Rossi et al, 2012).…”

The characterization of benthic communities at the Burdwood Bank slope (≥200 m depth) is provided, comprising data from the marine protected area (MPA) Namuncurá II (created in December 2018), as well as from some deep bathyal surrounding areas in the Southwest Atlantic Ocean. This information was acquired during two research cruises with RV Puerto Deseado (Argentina) during 2016 and 2017. Marine animal forests were detected in the study area: coral gardens, mainly composed of alcyonaceans, were detected in the south and west of Burdwood Bank (MPA Namuncurá II) and neighbouring areas, whereas pennatulacean aggregations were detected in the north‐west of the plateau. The three‐dimensional structures of live but also dead corals provide substrate and refuge to many associated species. Benthic communities dominated by sponges were also recorded between 200 and 300 m in depth. Six sites that meet the characteristics of vulnerable marine ecosystems (VMEs) are reported. Conservation strategies applied to scarcely known austral Argentinean waters led to the establishment of a pioneer MPA (Namuncurá I). Following the management plan that aimed to establish the biodiversity of Namuncurá I and neighbouring areas, the area of protection has now been enlarged to include the southern slope of the bank (currently Namuncurá II), where marine animal forests were detected, at depths below 200 m. The data presented here provide empirical evidence to support the conservation value of the region.

“…In particular, 12 genera are more frequently reported in shallow waters, and among them, Distichopora, Stylaster and Stylantheca show a bathymetric range including very shallow depths (1-806 m, 0-1845 m and 0-27 m, respectively) (Lindner et al 2008;Cairns 2011). Stylasterids are listed among hydrozoans forming perennial 'forests' that have a role in the energy transfer from plankton to benthos, collecting organic particles from the water column (Di Camillo et al 2017). In fact, in different geographic areas, they form vast mono-or multi-specific aggregations.…”

This work focuses on the carbonate factories constituting the Pietra di Finale Fm cropping out in the Ligurian Alps. This unit constituted a mixed carbonate–siliciclastic coastal wedge developed during the Middle Miocene. The carbonate factories characterizing the coastal wedge of the Pietra di Finale clearly differ from those of the coastal mixed systems and carbonate platforms developing during the Miocene elsewhere in the Mediterranean area. Here, in the Ligurian Alps, the euphotic carbonate factory does not show any evidence of seagrass meadows and coral bioconstructions. Zooxanthellate corals are present only as skeletal debris associated with abundant stylasterids. In the mesophotic and oligophotic zones, the typical oligophotic biota of red algae and larger benthic foraminifers are strongly reduced. The coastal wedge of the Pietra di Finale shows an unusual abundance of stylasterids, classically interpreted as deep-water biota. However, in this example, the absence of low-energy textures and other skeletal components suggest a shallow-water origin, probably in the eu- or mesophotic zone. The stylasterids colonized the hard substrates available and were successively removed and resedimented to form the skeletal fraction of the coastal wedge of the Pietra di Finale. The abundance of stylasterids is restricted to particular and limited situations in the Miocene of the Mediterranean, thus suggesting that their abnormal development is controlled by local rather than global factors.
