Researchers have discovered a new player in aquatic environments that thrives on nitrate.
Diatoms – unicellular organisms – have long been known to science, but their overwhelming appetite for nitrate is a new discovery made in a global survey.
Nitrate is a nutrient, widely used as fertilizer in agriculture, and today, nitrate concentrations in Earths aquatic systems are a lot higher than in pre-industrial times.
– There is too much nitrate in rivers, fjords and coastal ecosystems today. What happens to it? Will it further accumulate? Or will it be consumed – and by whom? Our new study helps answer these questions, said Peter Stief, associate professor at Department of Biology, University of Southern Denmark.
