Abstract

Forest ecosystems are increasingly vulnerable to environmental changes, including rising temperatures, shifting precipitation patterns, and persistent water stress. These changes disrupt essential physiological processes such as photosynthesis, transpiration, and nutrient uptake, directly impacting forest productivity, species distribution, and carbon sequestration capacity. Moreover, fluctuations in temperature and water availability influence tree growth trends, contributing to biodiversity loss and altering ecosystem dynamics. At the molecular level, trees exhibit gene expression modifications in response to climatic stressors, indicating potential adaptation mechanisms. This review explores the complex interactions between forest ecosystems and environmental changes, emphasizing key processes such as nutrient cycling, soil health, and microbial activity. We analyze the effects of extreme temperatures, drought, and excessive rainfall on tree physiology and ecosystem stability, highlighting species-specific adaptive strategies, including altered nutrient allocation, root modifications, and physiological adjustments. Additionally, we discuss human interventions such as targeted fertilization, biochar application, and sustainable land management as potential mitigation strategies to enhance forest resilience. Understanding the physiological, morphological, and molecular responses of forests to climate variability is crucial for developing adaptive management strategies. By integrating scientific insights into forest conservation and management, this review proposes innovative approaches to safeguard forest ecosystems against environmental stressors, ensuring their long-term sustainability and continued role in global climate regulation.
