Global warming and local eutrophication simultaneously lower oxygen (O2) saturation and
increase biological O2 demands to cause deoxygenation. Tropical shallow waters, and their …

The deep sea, the largest ecosystem on Earth and one of the least studied, harbours high
biodiversity and provides a wealth of resources. Although humans have used the oceans for …

Water masses can become undersaturated with oxygen when natural processes alone or in
combination with anthropogenic processes produce enough organic carbon that is …

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 …

Biological structures exert a major influence on species diversity at both local and regional
