This Ecotron facility will initially consist of 12 units where monoliths of 1 m² and 1 m depth can be installed in lysimeters. It can harbor small-statured ecosystems, such as grasslands or crops. By sampling inlet and outlet air, trace gas fluxes (CO2, H2O, in the future possibly CH4, N2O) are continuously determined in the units, which serve as growth environment as well as “ecosystem analyzer”. As biogeochemical cycles are often tightly coupled, the simultaneous measurement of these fluxes - in the long run also in combination with stable isotope determinations - will advance understanding relative to focusing on single or few fluxes. This Ecotron is capable of imposing temperatures well above ambient temperatures (up to +12 K), and together with the hosts' expertise in the domain, is suitable for climate extreme research.The platform will be situated on the University of Antwerp campus, and will be operational in 2022.

Relevant Research Questions

Highly-instrumented Ecotrons (environmentally controlled chambers) advance understanding of interacting processes by testing specific combinations of forcing variables, and measuring gas fluxes in an automated way (Roy et al. 2021). Multiple key questions regarding climate change, biodiversity loss, eutrophication and other global change factors can be addressed. We especially welcome research into climate extremes.

Advantages

  • newly built, state-of-the-art facility
  • automated whole-system gas fluxes 
  • controlled micro-environment (CO2, temperature, air humidity, soil moisture)
  • capable of warming well above ambient temperatures

Limitations

This platform is currently under construction.
