Phenology of Ecosystem Processes Applications in Global Change Research

About this book

Changes in the seasonal timing of ecosystem carbon, water and energy exchange are key sources of variation in biosphere-atmosphere feedbacks. Referencing this variability to traditional phenological events, such as bud break or flowering, introduces additional uncertainty with little mechanistic relationship to the process of interest. Instead, the seasonal cycles of each process must be understood in the context of biological and environmental factors that affect it. Some processes, like photosynthesis, are represented with high degree of realism and accuracy in several existing ecosystem process models, whereas others still have significant uncertainties.

Phenology of Ecosystem Processes summarizes the current understanding of the seasonality of ecosystem carbon and water cycles in the temperate and boreal zones using eight case studies, highlighting sources of variability, necessary additional measurements and novel ways to analyze existing datasets. It also includes syntheses of the interaction between water and carbon fluxes as mediated by constraints from plant anatomy to the ecosystem level.
