Over 85% of plants, including 2/3 of all crops, rely on animals for sexual reproduction. What lures animals to perform lurid favors for plants? Through the study of plant-pollinator interactions, this course will examine ecology and evolution as drivers of species- and individual-level cooperation and specialization, and critically examine cooperation and specialization as drivers of evolution. Pollinators are diverse, yet the importance of pollinator diversity per se to agricultural production remains unclear. We will review evidence for the link between pollinator diversity and the provision of pollination services, and ask when practices that promote “ecosystem services,” like pollination, and practices designed to support and restore biodiversity are congruent. We will engage with conceptual and empirical feedbacks between biological conservation and human well-being.
