Classic debates in community ecology focused on the complexities of considering an ecosystem as a super-organ or organism. New consideration such perspectives could clarify mechanisms underlying dynamics forest carbon dioxide (CO2) uptake and water vapor loss, important for predicting managing future Earth's ecosystems climate system. Here, we provide rubric traits aggregated, systemic, emergent, i.e., representing aggregate its individuals metaphorical literal We review recent approaches to scaling-up plant relations (hydraulics) concepts developed organs organisms enable interpret measurements at ecosystem-level. focus three community-scale versions that have potential mechanistic insight into change responses CO2 H2O gas exchange productivity: leaf (Ψcanopy), pressure volume curves (eco-PV), hydraulic conductance (Keco). These analyses can reveal additional ecosystem-scale parameters analogous those typically quantified leaves plants (e.g., wilting point vulnerability) may act thresholds drought, including growth cessation, mortality, flammability. unite these novel framework predict Ψcanopy approaching critical during using Keco eco-PV curves. thus delineate how extension from organ- organism-scales constraints interaction vegetation new understanding prediction use productivity.
