After taking this course, the student should be able to: * Display an appreciation of the richness of interactions between plants and herbivores at the biochemical, physiological, and toxicological levels. * Describe the host-finding and food-selection mechanisms of a number of herbivores, relating these to the properties of the plants and the environments in which they are found. * Describe a number of named examples of plant defensive mechanisms and herbivore strategies to overcome these. * Understand the feeding behaviour of herbivores in terms of optimal foraging and optimal digestion/nutrition strategies. * Relate the present status of plant-herbivore interactions to the existence of past evolutionary arms races. * Discuss other kinds of plant-animal interactions, including mutualisms connected with pollination, seed dispersal, and the trophic relations between carnivorous plants and their prey. * Display a critical appreciation of the experimental and field ecological methods used to study these phenomena. Content: Various examples of plant herbivore and other kinds of plant-animal interactions, taken from the scientific literature will be presented in introductory lectures, will form the subject of directed study by the class, and will be presented as topics in student led seminars.
