Enclosed ecosystem platforms (or ‘in vitro’): controlled environments dedicated to the analysis of processes involved in natural ecosystems or sub-systems within a research facility, for greater control over environmental variables (e.g. from preindustrial to future environmental conditions) and facilitated measurements. They possess inbuilt, often continuous, on-line, measurement systems for a wide array of environmental conditions (air, soil and canopy) and ecosystem processes (e.g. water, carbon, nitrogen fluxes). Isotopic labelling and isotopic fractionation are available in some of these platforms for a more in depth analysis of ecosystem functions.  These facilities enable efficient hypothesis testing and quantitative analysis of natural ecosystem functions.

The AnaEE call for interest received 44 submissions from enclosed ecosystem platforms.
