Eutrophication: a new wine in an old bottle?
Eutrophication is one of the most common causes of water quality impairment of inland and
marine waters. Its best-known manifestations are toxic cyanobacteria blooms in lakes and …

Gulf of Mexico hypoxia, aka “The dead zone”
The second largest zone of coastal hypoxia (oxygen-depleted waters) in the world is found
on the northern Gulf of Mexico continental shelf adjacent to the outflows of the Mississippi …

The nitrogen cascade
Human production of food and energy is the dominant continental process that breaks the
triple bond in molecular nitrogen (N2) and creates reactive nitrogen (Nr) species. Circulation …

Consequences of human modification of the global nitrogen cycle
The demand for more food is increasing fertilizer and land use, and the demand for more
energy is increasing fossil fuel combustion, leading to enhanced losses of reactive nitrogen …

Nitrogen transformations
Nitrogen is essential for life on Earth. Soil biota are responsible for its accumulation,
persistence, and loss from ecosystems. Microbial nitrogen transformations include its …

Legacy nitrogen may prevent achievement of water quality goals in the Gulf of Mexico
In August 2017, the Gulf of Mexico's hypoxic zone was declared to be the largest ever
measured. It has been estimated that a 60% decrease in watershed nitrogen (N) loading …

The jellyfish joyride: causes, consequences and management responses to a more gelatinous future
Human-induced stresses of overfishing, eutrophication, climate change, translocation and
habitat modification appear to be promoting jellyfish (pelagic cnidarian and ctenophore) …
