Abstract Whale carcasses create remarkable habitats in the deep-sea by producing concentrated sources of organic matter for a food-deprived biota as well places evolutionary novelty and biodiversity. Although many faunal patterns on whale falls have already been described, biogeography these communities is still poorly known especially from basins other than NE Pacific Ocean. The present work describes community composition deepest natural carcass described to date found at 4204 m depth...
Abstract The increasing demand for metals is pushing forward the progress of deep‐sea mining industry. abyss between Clarion and Clipperton Fracture Zones (CCFZ), a region holding higher concentration minerals than land deposits, most targeted area exploration polymetallic nodules worldwide, which may likely disturb seafloor across large areas over many years. Effects from nodule extraction cause acute biodiversity loss organisms inhabiting sediments nodules. Attention to ecosystems their...
Abstract Productivity and environmental stress are major drivers of multiple biodiversity facets faunal community structure. Little is known on their interacting effects early assembly processes in the deep sea (>200 m), largest environment Earth. However, at hydrothermal vents productivity correlates, least partially, with stress. Here, we studied colonization rock substrata deployed along a deep‐sea vent gradient four sites without direct influence fluids 1,700‐m depth Lucky Strike...
Whale falls are important environments contributing to biodiversity, connectivity and evolutionary novelty in deep-sea ecosystem. Notwithstanding, most of this knowledge is based studies from NE Pacific basin. Interestingly, the only known natural whale fall on SW Atlantic has faunal composition affinities with carcasses other deep-ocean basins. In carcass, annelid worms belonging Hesionidae abundant species-rich, include some shared species Ocean. Here we evaluate diversity using new...

The unique ecosystems and biodiversity associated with mid-ocean ridge (MOR) hydrothermal vent systems contrast sharply surrounding deep-sea habitats, however both may be increasingly threatened by anthropogenic activity (e.g., mining activities at massive sulphide deposits). Climate change can alter the through increased bottom temperatures, loss of oxygen, modifications to deep water circulation. Despite potential these profound impacts, mechanisms enabling their persist, function respond...
Abstract The recently discovered deep-sea Capelinhos hydrothermal edifice, ~ 1.5 km of the main Lucky Strike (LS) vent field (northern Mid-Atlantic Ridge), contrasts with other LS edifices in having poorly-altered end-member fluids low pH and chlorine, high metal concentrations. unique chemistry location offer opportunity to test effects local abiotic filters on faunal community structure while avoiding often-correlated influence dispersal limitation depth. In this paper, we characterize for...
At the nearly pristine hydrothermal vents of deep sea, highly endemic animals depend upon bacteria nourished by fluids that emerge as outflows from seafloor. These are remarkable in tolerating extreme conditions, including high heat, toxic reduced sulfide, and low oxygen. Here, we test whether vent environment has selected for functionally similar species across world’s ocean, despite well-established global geographic patterns phylogenetic distinctness. High functional redundancy pools...
Whale carcasses create habitats in the deep sea which are colonized by organisms related to other chemosynthetic environments suggesting that whale falls may act as intermediate refugia for dispersal and evolution of deep-sea organisms. Such evidence comes mainly from macrofaunal whereas smaller meiofauna, data on whalebone assemblages is lacking. In this study, we investigated nematode colonization whalebones experimentally deployed at 1500 3300 m depth bones a natural carcass found 4204 m,...
