Kok Effect Paper Out! 

9/19/2013

 
In December 2010, as a qualification exam for my graduate program, I wrote a directed literature review on the light inhibition of respiration (the "Kok Effect") and how it can be scaled upward to the ecosystem level. Two years later in December 2012, I submitted a much revised version of this paper to Ecosphere, the open access journal of ESA. 

This is the first review I've submitted, and it did not include datasets or a meta-analysis of data from other papers...making review a bit challenging for me and the reviewers. However, after a resubmission, extra focus on current scaling potential, and a deeper look into modeling, the paper was accepted in Summer 2013. 

This paper urges the incorporation of the light inhibition of respiration in estimates of net ecosystem exchange. It was a great experience to delve so deeply into a topic that is rarely considered outside of our lab group.
