Plant community light efficiency: measuring light response as a function of both photosynthesis irradiance.
Abstract
Light response is a unique plant trait that is caused by a species level adaptation to a particular light environment and leaf morphology. By ignoring individuals and focusing on communities as a whole, I was better able to understand how irradiance levels shape plant life. I measured some key characteristics of light responses: dark respiration, maximum rate of photosynthesis, and light compensation point as functions of light environment, reduced light environment, and leaf traits. The leaf area of the dominant species has a strong relationship to light compensation point and the maximum rate of photosynthesis of the community. Leaf mass per area had a negative correlation to dark respiration rates. The association between the leaf traits and light response characteristics demonstrated how communities respond to differences in irradiance levels.
