The half-moon shaped holes on this newly unfurled leaf are bite marks of a grasshopper that tasted the leaf and found this particular one unappealing. It moved down to feed on older tissue at the base of the plant.

Induced plant defenses across a nutrient gradient

One of my dissertation chapters focuses on a greenhouse study, where I examined the plasticity of plant defensive strategies (resistance and tolerance) in Solidago altissima across a nutrient gradient. Genotypes exhibited distinct responses in plant traits and patterns of allocation,  which depended both on the nutrient level of the soil and the degree of herbivory. This chapter was recently accepted for publication in the journal Functional Ecology. Check it out here.
