Coastal eutrophication caused by anthropogenic nutrient inputs is one of the greatest threats
to the health of coastal estuarine and marine ecosystems worldwide. Globally,∼ 24% of the …

The tropics contain the overwhelming majority of Earth's biodiversity: their terrestrial,
freshwater and marine ecosystems hold more than three-quarters of all species, including …

Growing populations and agricultural intensification have led to raised riverine nitrogen (N)
loads, widespread oxygen depletion in coastal zones (coastal hypoxia) and increases in the …

Ocean deoxygenation is predicted to threaten marine ecosystems globally. However, current
and future oxygen concentrations and the occurrence of hypoxic events on coral reefs …

Regime shifts are large, abrupt, and persistent critical transitions in the function and structure
of ecosystems. Yet, it is unknown how these transitions will interact, whether the occurrence …

Because of human action, the Earth has entered an era where profound changes in the
global environment are creating novel conditions that will be discernable far into the future …

Scientists have advocated for local interventions, such as creating marine protected areas
and implementing fishery restrictions, as ways to mitigate local stressors to limit the effects of …

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

BACKGROUND Oxygen concentrations in both the open ocean and coastal waters have
been declining since at least the middle of the 20th century. This oxygen loss, or …

It is well established that a global sanitation crisis threatens humans. By comparison, much
less attention has been given to address the effects of this crisis on the health of ecosystems …
