Document Summary

We will primarily be studying plants as they are easier to study & a lot of research has been done. Plants are the primary producers and are crucial to the overall productivity of and ecosystem. Primary production: process that converts chemical/solar energy is converted to biomass. Biomass: mass of living material in a given area or volume (aquatic) Gas exchange: flux towers (eddy co-variance) [regional scale] Measures co2 exchange of an area (micro-climatology: remote sensing [global scale] Only measures radiation (requires a model: models [global scale] 1 & 2 are used to calibrate the global models used in 3 & 4. As co2 increases photosynthesis increases, then plateaus. Growth increases with co2, but other factors also have an effect. Relative impact on different spp (c3 vs. c4) Long-term effects may be lessened at this scale, due to other interacting factors. Solar radiation is highest in the tropics & decreases as we approach the poles.
