Variations in deep-sea hydrothermal vent communities on the Mid-Atlantic Ridge near the Azores plateau
Near the Azores Triple Junction as the Azores Plateau is approached, the ridge axis becomes shallower; its depth decreases from ca. 2400 m in the Rainbow vent field (36°13′N) to ca. 850 m in theExpand
Nutritional relations of deep-sea hydrothermal fields at the Mid-Atlantic Ridge : a stable isotope approach
Nutritional relations among invertebrates from the hydrothermal vent fields at the Mid Atlantic Ridge were studied via the carbon and nitrogen stable isotope approach, providing a general picture of the community structure. Expand
Shallow water hydrothermal vent field fluids and communities of the D. João de Castro Seamount (Azores)
D. Joao de Castro seamount has an elevation of 1000 m and is located between the islands of Terceira and Sao Miguel, Azores, on the hyper-slow spreading Terceira Rift. The summit of the seamountExpand
Ecology of the Menez Gwen hydrothermal vent field (Mid-Atlantic Ridge Azores Triple Junction)
The Menez Gwen fauna is similar to the Lucky Strike fauna, but it differs markedly from the fauna previously described from other MAR hydrothermal areas. Expand
Hydrothermal Vents and Methane Seeps: Rethinking the Sphere of Influence
Although initially viewed as oases within a barren deep ocean, hydrothermal vent and methane seep communities are now recognized to interact with surrounding ecosystems on the sea floor and in theExpand
Temporal change in deep-sea benthic ecosystems: a review of the evidence from recent time-series studies.
The evidence for long-term changes both in biologically driven, sedimented, deep-sea ecosystems (e.g. abyssal plains) and in chemosynthetic ecosystems that are partially geologically driven, such as hydrothermal vents and cold seeps is assessed. Expand
Polar lipid fatty acids as indicators of trophic associations in a deep-sea vent system community
The polychaete Amathys lutzi shows the most diversified bacterial diet, with fatty acid biomarkers from both S-oxidizing and S-reducing bacteria. Expand
Non-indigenous marine species of the Azores
Marine benthic species introduced to the Azores are collated from scientific publications, internal reports and own data and are regarded as particularly invasive along the shores of this oceanic archipelago. Expand
A strategy for the conservation of biodiversity on mid-ocean ridges from deep-sea mining
This work adapts marine reserve design principles to the distinctive biophysical environment of mid-ocean ridges, offers a framework for design and evaluation of these networks, and introduces projected climate-induced changes in the deep sea to the evaluation of reserve design. Expand
Bioaccumulation of Hg, Cu, and Zn in the Azores triple junction hydrothermal vent fields food web.
In this work, mercury (Hg), copper (Cu) and zinc (Zn) concentrations and tissue distribution are determined in seven benthic invertebrates species (the key species) from the Mid Atlantic Ridge (MAR)Expand
