C9. Trees: Structure, Function, Ecology and Climate Change

Consider the world from a tree’s perspective. From the start of life as a tiny seed, trees must assimilate water and nutrients from the surrounding air and soils. As sessile creatures, trees must not only adapt to their increasing height and mass, but also a variable environment that features temperature extremes, heavy precipitation, and drought. How do trees communicate and interact with their surroundings, including other inhabitants of the forest? How are trees faring under climate change and how can trees help with it? We will visit the challenges and successes of trees, the ecology of life from roots to canopy, and the important role of trees in our changing New England climate.
