Article
Cold-water gorgonians dwelling on the continental shelf are a common by-catch of bottom-contact fishing practices. Given the slow growth and limited recruitment of cold-water gorgonians, the impact of fishing activities may seriously compromise the conservation of the highly complex coral gardens communities. For this reason, the development of eff...

Cold-water coral (CWC) habitats dwell on continental shelves, slopes, seamounts, and ridge systems around the world’s oceans from 50 to 4000 m depth, providing heterogeneous habitats which support a myriad of associated fauna. These highly diverse ecosystems are threatened by human stressors such as fishing activities, gas and oil exploitation, and...
Article
Full-text available
The survival, behavior and competence period of lecithotrophic larvae depends not only on the energy allocation transferred by maternal colonies but also on the amount of energy consumed to sustain embryonic, larval, and post-larval development. The objective of the present work is to understand the effect of energy consumption on the performance o...
Article
Full-text available
Knowledge about migration potential is key to forecasting species distributions in changing environments. For many marine benthic invertebrates, migration happens during reproduction because of larval dispersal. The present study aims to test whether larval size can be used as a surrogate for migration potential arising from larval longevity, compe...
Article
Gorgonians dwelling on the Mediterranean continental shelf are among the most frequent fishing bycatch taxa. These species display several traits, such as long lifespans and slow growth, which make them very vulnerable to the impacts caused by fishing activities with far‐reaching and long‐lasting effects. Hence, restoration and mitigation actions a...

of energy fluxes in marine animal forests of the Anthropocene: factors shaping the future seascape. Climate change is already transforming the seascapes of our oceans by changing the energy availability and the metabolic rates of the organisms. Among the ecosystem-engineering species that structure the seascape, marine animal forests (MAFs) are the...
Article
Full-text available
Anthropogenic climate change, and global warming in particular, has strong and increasing impacts on marine ecosystems (Poloczanska et al., 2013; Halpern et al., 2015; Smale et al., 2019). The Mediterranean Sea is considered a marine biodiversity hotspot contributing to more than 7% of world’s marine biodiversity including a high percentage of ende...
Article
• In the Mediterranean Sea, gorgonians are among the main habitat‐forming species of benthic communities on the continental shelf and slope, playing an important ecological role in coral gardens. • In areas where bottom trawling is restricted, gorgonians represent one of the main components of trammel net bycatch. Since gorgonians are long‐lived an...
Chapter
Mesophotic coral ecosystems (MCEs) and temperate mesophotic ecosystems (TMEs) have received increasing research attention during the last decade as many new and improved methods and technologies have become more accessible to explore deeper parts of the ocean. However, large voids in knowledge remain in our scientific understanding, limiting our ab...
Article
Full-text available
This study examined the sexual reproductive cycle, energy storage and metabolic requirements of a Mediterranean gorgonian in a mesophotic ecosystem (~70 m depth). Paramuricea macrospina resulted to be a gonochoric internal brooding species with a 1:1 population sex ratio. Oogenesis lasted ~12–14 months, whereas spermatogenesis was significantly sho...
Article
The cold-water coral (CWC) Dendrophyllia cornigera is widely distributed in areas of both high and low productivity, suggesting a significant trophic plasticity of this coral depending on the food available in the environment. In this study, lipid biomarkers and their isotopic signature were compared in colonies of D. cornigera and sediment from th...

The temperate coralligenous bioconcretions are mainly built by the accumulation of encrusting coralline algae growing at low irradiance levels. They harbour approximately 10% of marine Mediterranean species (about 1600 species), including long-lived algae and invertebrates. Enhanced by climate change, several pressures affect coralligenous assembla...

Article
This study investigates the energetic investment in larval release of two Mediterranean gorgonians with different trophic strategies: Eunicella singularis (mixotroph) and Corallium rubrum (heterotroph). Both are internal brooders, releasing larvae within few weeks in summer. A biochemical approach, based on the analysis of stable isotopes, total li...
Technical Report
The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise targeted areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where Cold-water corals (CWCs) have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting faun...
Chapter
Animal forests all over the world play an essential role in benthic-pelagic coupling processes. These processes can change according to the feeding strategies of benthic species, as well as their extension and biomass. From the oligotrophic coral reefs to the highly seasonal productive Antarctic ecosystems, suspension feeders (the main eco-engineer...
Thesis
Full-text available
Sexual reproduction is one of the fundamental biological processes for most living species, it is essential for the perpetuation of the species and to ensure genetic diversity. In marine sessile invertebrates, such as corals and gorgonians, sexual reproduction is also important because it allows the dispersal of individuals, facilitating the coloni...
Article
Full-text available
Understanding processes that contribute to a better comprehension of the population dynamics of long-lived species is critical for the maintenance and potential recovery of such species. Despite the abundance of soft corals in Mediterranean rocky reefs, little information exists on their life histories and reproductive patterns. In this study, we a...
Article
Knowledge of the nutritional conditions of coastal commercial fish populations is key to understanding stock health status, and is essential when making reasonable exploitation and management plans. Here, we present the first results on the condition and feeding preferences of two coastal fish species, Diplodus sargus (Linnaeus, 1758) and Pagellus...
Article
Full-text available
Larval dispersal is the process enabling connectivity between populations of marine species with a sedentary adult stage. This transportation results from the coupling between flow and larval biological traits. This experimental study aims to quantify these larval biological traits, namely pelagic larval duration (PLD), buoyancy, and larval vertica...
Article
Biogeochemical signatures derived from organisms thriving in the ocean water column are driven by environmental conditions, with highly complex processes linking primary and export productivity. Organic matter input, in-situ production and fate depend on conditions such as sea surface temperature, ice-cover and freshwater input, mixing/stratificati...
Article
Full-text available
The annual gonad development of a shallow (20 m depth) population of the Mediterranean gorgonian Eunicella singularis was found to be closely synchronized with that of a deep (60 m depth) population, but differences were observed in the gonadal output, with the shallow population producing more and larger sexual products. Lipid content in the shall...
Article
Full-text available
In order to better understand the sources, patterns and consequences of anthropogenic effects on populations of the Mediterranean gorgonian Paramuricea clavata, we examined the proportion of injured colonies among populations exposed to a combination of anthropogenic disturbances (recreational cast fishing, commercial lobster pots, gill nets and SC...
Conference Paper
Full-text available
The increasing interest in marine protected areas applying a holistic ecosystem approach has expanded beyond the littoral zone. In order to sustainably manage coastal marine reserves, the entire continental shelf and upper slope should be protected. Recent findings in cold-water corals have influenced the Natura 2000 Network program, which is creat...
