can initially act as a fertilizer, increasing photosynthesis and water-use efficiency (WUE), these benefits are often offset by extreme temperatures and drought, which can trigger "carbon starvation" and hydraulic failure. 1. Disruptions to Water Relations

Global change impacts tree physiology and forest ecosystems primarily by disrupting water and carbon cycles, leading to widespread physiological stress and altered growth patterns . While rising CO2cap C cap O sub 2 Impacts of Global Change on Tree Physiology and...

: During severe drought, excessive water tension in the xylem can cause "cavitation" (air bubbles), blocking water transport from roots to leaves and leading to tree death. can initially act as a fertilizer, increasing photosynthesis

Climate change creates a complex "tug-of-war" in tree carbon balances, affecting their role as global carbon sinks. 5 Ways Climate Change Impacts Forests can initially act as a fertilizer
