Combined Effects of Drought and Herbivory on Tea Metabolism

Importing data from a LI-COR photosynthesis meter into R

The LI-6400XT is a portable device used to measure photosynthesis in plant leaves. As you take measurements by pressing a button on the device, they are recorded into memory.

Quantifying leafhopper damage with automated supervised classification

As part of my fieldwork in China, I collected harvested tea leaves that were damaged by the tea green leafhopper. I want to quantify the amount of leafhopper damage for each harvest.

Non-linear effects of tea green leafhopper (Empoasca onukii) density on tea (Camellia sinensis) secondary metabolites and implications for tea quality.

Plant metabolic responses to herbivory are generally elucidated using experiments that compare the metabolite concentrations in attacked plants to un-attacked plants. In these experiments, herbivore density is often arbitrary, and may only elicit one …
