IARC research faculty Jessie Cable will discuss her work on Bayesian modeling approaches and their connection to hydrology research.
Boreal Forest Ecohydrology: Integrative Modeling of Freshwater Production
Integration of field, lab, and Bayesian modeling approaches reveal the response of plant water flux to environmental conditions
Arguably, the link between ecology and hydrology is stronger in sub-Arctic and Arctic systems than in any other system. Yet we lack an integrative framework to merge these two disciplines and quantify how climate change alters freshwater production in the Boreal forest. For this reason, it is difficult to quantify relevant environmental conditions, constraints, and their controls on transpiration. For example, changes in air temperature, humidity, permafrost (and consequently, soil temperature and moisture), and vegetation composition will all contribute to altering boreal plant transpiration.
The goal of my research is to integrate field-, lab-, and process-based models within a Bayesian statistical framework to better quantify the effects of environmental and soil conditions on plant transpiration from the two dominant Boreal systems (coniferous forests with permafrost, deciduous forests without permafrost). This research highlights the importance of temporal and spatial variability in environmental and soil conditions for transpiration by quantifying the effect of antecedent soil moisture and temperature. It also notes the depths at which these variables are important. This research also produces a predictive framework that utilizes widely available environmental data to quantify transpiration over large scales.
