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.

"This edited volume extends the traditional organismal focus of phenology to include ecosystem-level processes [...] . This volume is most appropriate for scientists interested in understanding and tracking temporal (diel, seasonal, interannual) dynamics of carbon across a variety of spatial scales [...] . cleverly illustrates the relationship between structure and function over time, with standard acronyms serving as codes to more experienced scientists. [...] chapters contain content, detail, and analyses that would be most appropriate for the advanced undergraduate student and beyond."
