W'14 Colloquium in Plant Physiology and Biochemistry

Overview:

Colloquium in Plant Physiology and Biochemistry, Winter 2014
Theme is the ‘Effect of Climate Change on Plant Physiological Processes and Agriculture’

Title: Plant-arthropod interactions in the context of rising CO2 concentration
Presenter: Jonathan Newman, School of Environmental Sciences, University of Guelph

 

ABSTRACT:

In this talk I first discuss the results from several of my studies investigating the interactions between grasses, their endophytic fungi, and their arthropod herbivores, as they respond to rising carbon dioxide concentrations. I will then place this work in a much broader context of the impacts of climatic change on plant-arthropod interactions. I will do this by way of a meta-analysis of >5000 data points extracted from 270 papers published between 1979 and 2009. I hope to convey to the audience what it is like to work in this field, what is the current state of knowledge, and where we might go from here.
