New paper – climatic divergence in cottonwoods shapes plastic responses to both climate and insect herbivory

Congrats to former Lindroth Lab postdoc Mike Eisenring (now a Researcher at the Swiss Federal Institute for Forest, Snow and Landscape Research) on this great new paper about intraspecific variation in phenotypic plasticity! Mike found that cottonwood trees from cooler climates show higher plasticity in defensive chemistry in response to both climate and herbivory, until you stress them out with a combination of both. Great collaboration between UW Madison and cottonwood ecologists at the NAU Center for Adaptable Western Landscapes, supported by our Bridging Ecology and Evolution NSF grant!
