Welcome to the Nutrient Network!

Two of the most pervasive human impacts on ecosystems are alteration of global nutrient budgets and viagra tablets sale changes in the abundance and best viagra price identity of consumers. Fossil fuel combustion and fast get viagra without prescription agricultural fertilization have doubled and how to take cialis pills quintupled, respectively, global pools of nitrogen and order viagra in canada phosphorus relative to pre-industrial levels. Concurrently, habitat loss and viagra online sales degradation and price cialis selective hunting and max viagra dose fishing disproportionately remove consumers from food webs. At the same time, humans are adding consumers to food webs for endpoints such as conservation, recreation, and agriculture, as well as accidental introductions of invasive consumer species. In spite of the global impacts of these human activities, there have been no globally coordinated experiments to quantify the general impacts on ecological systems. The Nutrient Network (NutNet) is a grassroots research effort to address these questions within a coordinated research network comprised of more than 40 grassland sites worldwide.

NutNet focal research questions:

  1. How general is our current understanding of productivity-diversity relationships?
  2. To what extent are plant production and generic viagra in canada diversity co-limited by multiple nutrients in herbaceous-dominated communities?
  3. Under what conditions do grazers or fertilization control plant biomass, diversity, and composition?

NutNet goals:

  1. To collect data from a broad range of sites in a consistent manner to allow direct comparisons of environment-productivity-diversity relationships among systems around the world. This is currently occurring at each site in the network and, when these data are compiled, will allow us to provide new insights into several important, unanswered questions in ecology.
  2. To implement a cross-site experiment requiring only nominal investment of time and buy cialis on line resources by each investigator, but quantifying community and generic cialis next day delivery ecosystem responses in a wide range of herbaceous-dominated ecosystems (i.e., desert grasslands to arctic tundra).

NutNet membership:

NutNet membership is open to ecologists who are committed to either intiating a new NutNet node, collaborating with researchers at an exitisting network site, or furthering the network goals in other substantive ways. There are two primary rules of membership:
  1. You must play well with other members of the team, and
  2. You must carefully follow the research protocol for the core sampling.
