Streams and rivers process and transport carbon to downstream systems and are important components of global and regional carbon budgets. Ecosystem functions, including gross primary production (GPP) and ecosystem respiration (ER), can be used to improve understanding of carbon cycling and ecosystem health in lotic systems. Whole-stream metabolism (GPP and ER) has been studied extensively in headwater streams. However, we know less about the variability in GPP and ER in aridland rivers and tributary streams despite being globally abundant and vulnerable systems to changing climate. This dissertation explores temporal and spatial variation of GPP and ER in a montane stream …
