Cold-water coral (CWC) systems are hotspots of biodiversity that need protection from the increasing human impacts and global climate change. The restoration of degraded cold-water coral reefs may be conducted through transplantation of nubbins. To do so, we need to set up the optimal conditions for CWCs livelihood in an aquarium setting. Here we i...

Population connectivity studies are a useful tool for species management and conservation planning, particular of highly threatened or endangered species. Here, we evaluated the genetic structure and connectivity pattern of the endangered coral Cladocora caespitosa across its entire distribution range in the Mediterranean Sea. Additionally, we exam...
Article
Full-text available
The 30–150 m bathymetric range is commonly adopted in the literature to constrain the mesophotic zone. However, such depth interval varies depending on sunlight penetration, which is primarily a function of solar radiation incidence and water clarity. This is especially obvious in the Mediterranean Sea with its peculiar biophysical properties. Inte...
Article
Full-text available
The neodymium isotopic composition (εNd) of seawater is one of the most important geochemical tracers to investigate water mass provenance, which can also serve as a proxy to reconstruct past variations in ocean circulation. Nd isotopes have recently also been used to reconstruct past circulation changes in the Mediterranean Sea on different time s...

Cover Story : Carbonate skeletonized organisms such as bryozoans, mollusks, echinoderms, cnidarians, barnacles, serpulids, foraminifers, ostracods, and red algae occur in Antarctic marine biota today. Depending on the different carbonate polymorphs secreted and postmortem circumstances, their skeletal remains play a major role in reconstructions of...
Article
Full-text available
The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as t...
Article
Full-text available
Marine biogenic skeletal production is the prevalent source of Ca-carbonate in today’s Antarctic seas. Most information, however, derives from the post-mortem legacy of calcifying organisms. Prior imagery and evaluation of Antarctic habitats hosting calcifying benthic organisms are poorly present in the literature, therefore, a Remotely Operated Ve...
