Name the 3 ways in which you can measure the effects of incresaed CO2 on forests
1. exposure of leaf to high co2 2. expose whole plant to high CO2, 3. expose whole ecosystem to high CO2
1 of 9
What are the effects when exposing a leaf to high CO2? (3)
internal plant CO2 lower then outside, increased photosynthesis, increased rubisco activity
2 of 9
What are the effects of FACE? (4)
fast growing trees maintain enhanced growth, mature trees show altered growth morphology, leaves change e.g. green and longer, changes in soil chemistry
3 of 9
What does FACE stand for?
free air CO2 environment
4 of 9
What are the 3 ways you can expose a whole plant to high CO2?
Growth chamber studies, greenhouse studies and open top chambers
5 of 9
what are the effects of exposing a whole plant to high CO2?
increased photosynthesis but decreased capacity, acclimation of the plant- invest less into C capture
6 of 9
What are the physiological effects of increasing temperature on trees? (4)
incresed photosynthesis and respiration, overall increase in growth, indirect effect on water relations, incresaes disease susceptibility
7 of 9
what are the effects on soil processes with an increased temperature? (3)
increased respiration and microbial growth, decay of organic matter, N cycling increases
8 of 9
How will rainfall change in the future?
change in rainfall patterns effecting plant growth, causing a spread in temperate forests
