Article
Full-text available
The impact of bottom trawling on cold-water corals (CWC) has been thoroughly studied and shown to be long-lasting; however the effects of bottom longlining on CWC ecosystems have received little attention. The present paper identifies the principal CWC species landed by bottom longlining in Faial (Azores) from 150 to 600 m depth. Data were obtained...

The submarine Azores Plateau in the Central Northern Atlantic has generally been considered to represent a large igneous plateau formed some 10 Ma by widespread volcanism, however a lack of age progression amongst the younger submarine and subaerial volcanism, an irregular distribution of platform-related magmas east and west of the Mid-Atlantic Ri...
Article
Full-text available
Mid-ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension-and filter-feeding organisms, such as cold-water corals and deep-sea sponges. However, the pioneering work conducted along the Mid-Atlantic Ridge failed to report the presence of large and dense living coral reefs, coral...
Article
Octocorals are prominent habitat builders in deep-sea ecosystems. The octocorals Dentomuricea aff. meteor and Viminella flagellum are common deep-sea octocoral species in the Azores Archipelago, where they form dense, structurally complex and diverse communities between 150 and 600 m of depth. The objective of this study was to determine the reprod...

Article
Full-text available
The deep sea plays a critical role in global climate regulation through uptake and storage of heat and carbon dioxide. However, this regulating service causes warming, acidification and deoxygenation of deep waters, leading to decreased food availability at the seafloor. These changes and their projections are likely to affect productivity, biodive...

The main purpose of this STSM was to start the 3rd year of my PhD project by learning molecular techniques applied to the discrimination of octocoral species in the deep-sea of the Atlantic Ocean. Available at https://www.oceangov.eu/wp-content/uploads/2019/04/OG-STSM-Report_Sampaio.pdf
Presentation
Octocoral taxonomists are rare worldwide. Even in geographical areas like the NA Ocean, commonly considered well explored, taxonomical knowledge of Octocorallia is insufficient due to a lack of taxonomic effort. The NW African deep-sea is not as explored as the NWA Ocean, specifically the Mauritanian region. Only a few deep-sea research expeditions...
Article
Full-text available
Highly migratory, cosmopolitan oceanic sharks often exhibit complex movement patterns influenced by ontogeny, reproduction, and feeding. These elusive species are particularly challenging to population genetic studies, as representative samples suitable for inferring genetic structure are difficult to obtain. Our study provides insights into the ge...

Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, specificity and nature of their associations with their coral hosts. In this study, analyses of molecular data (mtDNA COI, 16S and...
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...
Technical Report
The research program of cruise M128 Azores Plateau mainly aimed at improving our understanding of the igneous and tectonic processes that occur during the initial emplacement of large igneous plateaus and the subsequent interaction between intraplate volcanism and ultraslow rifting. The sampling program targeted the oldest and youngest igneous volc...

Our results show an important unknown diversity of zoanthids associated with deep sea corals. The monophyly of octocoral associated zoanthids suggests that substrate specificity is tightly linked to the evolution of zoanthids. The parasitic behaviour of these octocoral associated zoanthids raises questions on their importance as a natural cause of...

Question
Crypthelia species are gonochoric. One of the characters used on the identification of species belonging to this genus is the formula developed by Cairns, 1986 which is based on the positioning of ampullae for both sexes. Size and position of the ampullae and efferent pores are indicators of the gender. However, some positions of ampullae are possible for both sexes. Is there any other way to distinguish one gender from the other?
Thanks a lot in advance.

Question
I am aware of the nature of this question, not truly scientific. Nonetheless, how many of us had to deal with nonsense comments on reviews of papers? I would like to learn with your expertise about this topic. When facts are not enough to argue a nonsense list of comments what do you do? 
Thanks in advance.
Question
While in Bayer et al., 1983 double disks are sclerites characteristic of several genus, capstans are one of the characteristic sclerites of Swiftia species. Is there any Swiftia where this kind of sclerites are present?
