Water limits plant productivity in many ecosystems across the globe and climate change has the potential to alter current rainfall distribution patterns. At the leaf level, plants basically trade water vapor for the carbon dioxide used in photosynthesis. Therefore, plants contribute large amounts of water vapor to the atmosphere and water stress has direct impacts on plant and ecosystem productivity. This talk will focus on two questions regarding whether water limitations impact plant growth and productivity: 1) Does water transport limit maximum tree height? This question will be examined using data collected from palm trees (Washingtonia robusta) growing at the LA County Arboretum. 2) How do co-occurring oak species compete in a water-limited ecosystem? This research was performed in the New Jersey Pine Barrens which is a pine/oak ecosystem situated on sandy soils with limited water-holding capacity. Taken together, this research highlights the role water plays in plant and ecosystem productivity and the adaptations plants employ to utilize water effectively.
