Altitude-induced variations in vegetation characteristics and soil properties

Abstract

Elevational gradients exhibit diverse patterns in species distribution and soil characteristics, creating distinct ecological zones. This paper aims to synthesize current knowledge on the relationships among elevation, environmental factors, plant families, and life forms to uncover the mechanisms driving these patterns. Species richness varies with elevation, with some plants declining while others thriving due to eco-physiological properties and functional traits. These elevational patterns differ among plant families and life forms. Intermediate elevation transition zones host diverse floras, with temperate species thriving at lower elevations than their primary habitats and tropical lowland species extending to higher elevations. Climatic conditions, area size, the mid-domain effect, and biotic processes, particularly water-energy dynamics, are crucial for understanding the intricate relationships between climate and vegetation. Changes in temperature and precipitation along altitudinal gradients significantly impact the attributes of soil. This review emphasizes the importance of microorganisms in nutrient cycling and the adaptability of psychrophilic bacteria and fungi to high-altitude environments. Understanding these complex interactions is essential for predicting the impacts of climate change and ensuring the sustainable management of high-altitude ecosystems. Further research into species richness patterns, soil dynamics, and microbial roles is necessary for developing effective conservation strategies and sustainable land management practices.
