The Nutrient Network (NutNet)
The Nutrient Network, or NutNet (nutnet.org), is a grassroots, ecological experimental network, established to address global ecological questions at a global scale - the Earth. NutNet was formed and is sustained by the individual efforts of more than 100 ecologists from all over the world, including many graduate students and early-career scientists. We are, of course, excited about the scientific questions, but also our do-it-yourself approach, and especially the rich collaboration opportunities with colleagues world-wide. Our ground rules are really simple rules that we teach in kindergarten: play well with others and share.
NutNet now includes over 100 sites, in more than 25 countries, and on 6 continents. One of the original questions we had when we formed the NutNet was how changes to multiple nutrients drive changes in plant biodiversity. We focus on grassland ecosystems because of their importance: they generate one-third of Earth's terrestrial production and account for 70% of agricultural land, and because of their value to sustaining food production they are also one of the most impacted ecosystem types.
PhyDiv is associated with sites in Europe and North America:
