Thesis Abstract

Abstract
Climate change is a pressing global issue that has far-reaching implications on various ecosystems, including plant communities. This study investigates the effects of climate change on plant phenology and physiology, aiming to provide insights into how plants are adapting to changing environmental conditions. The research focuses on understanding how shifts in climate patterns influence the timing of plant life cycle events and the physiological responses of plants to these changes. The study begins with a comprehensive review of the existing literature on climate change impacts on plant phenology and physiology. It explores the current understanding of how rising temperatures, altered precipitation patterns, and changing levels of atmospheric carbon dioxide affect plant growth, development, and reproduction. The literature review also examines the mechanisms through which plants respond to environmental stressors and the potential consequences for plant communities and ecosystems. Methodologically, this research employs a combination of field observations, laboratory experiments, and data analysis to investigate the effects of climate change on plant phenology and physiology. Field observations involve monitoring plant phenological events such as flowering, leaf emergence, and fruiting across different environmental conditions. Laboratory experiments focus on measuring physiological parameters like photosynthesis rates, stomatal conductance, and water use efficiency under controlled environmental conditions. Data analysis techniques include statistical modeling to assess the relationships between climate variables and plant responses. The findings of this study reveal significant impacts of climate change on plant phenology and physiology. Results indicate that rising temperatures lead to earlier flowering and leaf emergence in many plant species, disrupting the synchrony between plants and their pollinators or seed dispersers. Changes in precipitation patterns also affect plant water availability and stress responses, influencing plant growth and survival. Furthermore, elevated carbon dioxide levels alter plant nutrient uptake and allocation, influencing plant productivity and competitive interactions. The discussion of findings delves into the ecological implications of climate change-induced shifts in plant phenology and physiology. It highlights the potential consequences for plant community composition, ecosystem functioning, and biodiversity conservation. The study emphasizes the importance of considering plant responses to climate change in conservation and management strategies to mitigate the impacts of global warming on natural ecosystems. In conclusion, this research contributes to the growing body of knowledge on the effects of climate change on plant phenology and physiology. By elucidating the mechanisms through which plants respond to changing environmental conditions, the study provides valuable insights for understanding and predicting the impacts of climate change on plant communities. The findings underscore the urgent need for adaptive strategies to safeguard plant biodiversity and ecosystem resilience in the face of ongoing global environmental change.
