FCE 4.2 Conceptual Diagram Please reflect in the poster on how your work informs the science of the FCE and your discipline. FCE 4.2 Conceptual Diagram FCE conceptual diagram of the coastal social-ecological system describing the fate (∆) of regional carbon stocks as a function (⨏) of interactions among exogenous drivers, endogenous filters, and coastal ecosystem structure and function. The diagram shows how four FCE IV working groups (bold, italics) and four cross-cutting themes (bold) will be integrated to address three central questions (gray arrows). Q1: How do non-stationary climate and emergent socio-cultural dynamics interact with endogenous factors (landscape bio-geomorphic gradients and institutional/infrastructural legacies) to produce the coastal hydrologic disturbance regime? Q2: How do changes in the hydrologic regime and its endogenous drivers shape and respond to coastal ecosystem structure and function? Q3: How do non-stationary exogenous, endogenous and ecological factors determine: (a) whether carbon stocks continue to develop (yellow line), stabilize (black line) or decline (red line), and (b) feedbacks to exogenous drivers and endogenous filters.
