Five chrysopetalid species are reported from samples collected at bathyal depths in three NE Atlantic regions: the Bay of Biscay, Horseshoe Abyssal Plain and Gulf Cadiz. Arichlidon reyssi (Katzmann et al., 1974), Dysponetus caecus (Langerhans, 1880) D. profundus Böggemann, 2009 free-living forms found mainly on biogenic substrates (e.g., coral sunken wood). A brief description taxonomical remarks given for each these their geographical distributions habitat records were updated accordingly....
Abstract Determining seafood geographic origin is critical for controlling its quality and safeguarding the interest of consumers. Here, we use trace element fingerprinting (TEF) bivalve shells to discriminate specimens. Barium (Ba), manganese (Mn), magnesium (Mg), strontium (Sr) lead (Pb) were quantified in cockle ( Cerastoderma edule ) captured with two fishing methods (by hand by hand-raking) from five adjacent locations within an estuarine system (Ria de Aveiro, Portugal). Results...
Abstract. The Gulf of Cadiz is an extensive seepage area in the south Iberian margin (NE Atlantic) encompassing over 40 mud volcanoes (MVs) at depths ranging from 200 to 4000 m. has a long geologic history and central biogeographic location with complex circulation ensuring oceanographic connectivity Mediterranean Sea, equatorial North Atlantic regions. geodynamics region promotes notorious diversity seep regime despite relatively low fluxes hydrocarbon-rich gases. We analyse quantitative...
Organic falls create localised patches of organic enrichment and disturbance where enhanced degradation is mediated by diversified microbial assemblages specialized fauna. The view as "stepping stones" for the colonization deep-sea reducing environments has been often loosely used, but much remains to be proven concerning their capability bridge dispersal among such environments. Aiming clarification this issue, we used an experimental approach answer following questions: Are relatively...
The “Bathymodiolus” childressi group is the most geographically diverse assemblage of deep-sea mussel species. In this paper we consider several possible hypotheses to explain present biogeographic distribution “B.” species complex. Mussels were collected for first time from mud volcanoes in Gulf Cadiz (NE Atlantic Ocean) during training through research (TTR) 16 expedition 2006. Preliminary observations shell features indicate that they belong complex, which has been recognized as...
Understanding spatio-temporal variability of trace elements fingerprints (TEF) in bivalve shells is paramount to determine the discrimination power this analytical approach and secure traceability along supply chains. Spatio-temporal TEF was assessed cockle (Cerastoderma edule) using inductively coupled plasma-mass spectrometry (ICP-MS). Four elemental ratios (Mg/Ca, Mn/Ca, Sr/Ca Ba/Ca) were measured from specimens originating eight different ecosystems Portuguese coast, as well four areas,...
Abstract Sunken whale carcasses, known as ‘whale falls’, deliver large pulses of organic material to the seafloor and serve habitat islands for unique assemblages deep‐sea fauna that include generalist scavenging species, chemosynthetic related those from hydrothermal vents cold seeps, bone‐specialist species. Despite growing interest in this peculiar last decade, all long‐term studies whale‐falls have been restricted Pacific ecology these habitats Atlantic Ocean has overlooked. Here we...
Abstract Five mammal carcasses were experimentally deployed at 1000 m depth in the Setubal Canyon ( NE Atlantic) March 2011 and remaining bones collected after 18 28 months. High numbers (1.92–6.27 individuals·cm 2 ) of small mussels found among a diverse invertebrate assemblage colonizing surfaces, crevices cavities trabecular matrix bones. In this study we characterized mussel population their associated bacteria investigated structure settlement patterns. The results molecular analysis...
Abstract The ban on the use of tributyltin (TBT) is promoting an increasing copper as active biocide in antifouling paints, with consequent rising levels this metal environment.

Abstract. Bridging the Atlantic and Mediterranean continental margins, South Iberian region has recently been focus for geological biological investigations. In this region, Gulf of Cadiz (GoC) encompasses a great variety deep-sea habitats that harbour highly diverse communities. study, we describe composition gastropod assemblages obtained from in situ colonization experiments benthic sampling GoC. Gastropod distributional patterns, such as bathymetric ranges, turnover, affinity to...
Abstract Geochemical markers are being increasingly applied to fundamental questions in population and community ecology marine habitats because they allow inferences on individuals dispersal, but vital effects, small sample size instrumental limitation still challenging particularly deep-sea studies.

Recent advances in technology have enabled an unprecedented development of underwater research, extending from near shore to the deepest regions globe. However, monitoring biodiversity is not fully implemented political agendas and biological observations deep ocean been even more limited space time.
