What Trees Could Learn from Alan Greenspan Stephen Soerens Advisor: Adam Wolf Princeton Environmental Institute (PEI)

Why do we care about trees?  Forests are essential to the climate system – how will forests react to climate change?  Competition – Must outgrow and outlast neighbors to survive  Risk Management – Photosynthesis vs. Cavitation  Mechanisms of reaction and adaptation

Driving Questions  Why is this plant and not another plant in this location?  When does a plant no longer act in its best interest? - when does it lose to its competitors?  What plant will be here in _____ years?

Methods  How much water is the leaf pulling and how much is it evaporating?  Evaporative Flow Meter (Pressure Differential)  LI-COR Portable Photosynthesis System (gas exchange differential of CO 2 and H 2 O)
