Advances in Field Measurements across AmeriFlux: To Improve Our Understanding of the Relationship between Plant and Ecosystem Function
Session ID#: 161721
Session Description:
AmeriFlux is one of the largest science networks that provide carbon, water, and energy flux observations and meteorological data to offer valuable insight into ecosystem function across diverse ecosystems and climate regimes. Along with ecosystem-scale measurements of carbon, water, and energy exchange, researchers use many types of field measurements to understand plant responses to changing climate at an individual or cellular level, and how these responses impact ecosystem function. These organismal scale measurements are important considering the high heterogeneity in plant physiology both within and across species, and the substantial influence of microclimate on plant responses, which may not be captured by the larger footprint eddy covariance measurements. This session will highlight research that 1) combines eddy covariance and field measurements to examine the relationships between plant scale responses, vegetation structure, and ecosystem function, and 2) explores how these relationships can advance our understanding of patterns in ecosystem function across diverse environments and changing climates.
