The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats
TLDR
Overall spatial and temporal patterns of species diversity and major changes and threats were assessed, and temporal trends indicated that overexploitation and habitat loss have been the main human drivers of historical changes in biodiversity.
Deep, diverse and definitely different: unique attributes of the world's largest ecosystem
Abstract. The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet.
A Census of Marine Biodiversity Knowledge, Resources, and Future Challenges
TLDR
A global review of gaps in marine biodiversity knowledge and resources is overdue because society and many scientists believe the authors have discovered most species, or that doing so is out of fashion except when new technologies are employed.
Major viral impact on the functioning of benthic deep-sea ecosystems
TLDR
It is reported that viral production in deep-sea benthic ecosystems worldwide is extremely high, and that viral infections are responsible for the abatement of 80% of prokaryotic heterotrophic production.
Composition of organic matter in sediments facing a river estuary (Tyrrhenian Sea): relationships with bacteria and microphytobenthic biomass
TLDR
Analysis of biochemical composition of sediment organic matter and bacteria and microphytobenthic biomass distribution, along the coast of Northern Tuscany, suggests that specific organic compounds need to be measured rather than bulk carbon and nitrogen measurements in order to relate microbial biomass to the quality of organic matter.
Deep-Sea Biodiversity in the Mediterranean Sea: The Known, the Unknown, and the Unknowable
TLDR
It is shown that in contrast to what was expected from the sharp decrease in organic carbon fluxes and reduced faunal abundance, the deep-sea biodiversity of both the eastern and the western basins of the Mediterranean Sea is similarly high.
Extracellular DNA Plays a Key Role in Deep-Sea Ecosystem Functioning
TLDR
It is demonstrated that extracellular DNA accounts for about one fifth of the total organic phosphorus regeneration and provides almost half of the prokaryotic demand for organic phosphorus in deep-sea ecosystem functioning on a global scale.
