摘要

Quercus leucotrichophora, a keystone species in the Himalayan ecosystem, offers essential ecosystem services, such as water and soil conservation, fodder and fuel provision, and also in forest formation. Our study investigated resource utilization strategies of Quercus leucotrichophora along elevational gradients by analyzing leaf traits in the temperate forests of the Western Himalayan region. The leaf and stem trait data were collected by randomly selecting six trees of the species in each site from three different stands located at three elevations across the seasons. Analysis of variance revealed that morphological, physiological, and biochemical traits significantly contribute to the adaptation of Q. leucotrichophora across the three forest types, which have different environments measured along elevation. The results revealed that along the elevational gradient, specific leaf area, photosynthetic rate, and dark respiration rate increase, while leaf dry matter content decreases. The variation in traits along the elevation suggests a preference for resource conservation strategies that contribute to fast returns in investment, possibly in response to the harsh climatic conditions at higher elevations and the shorter growing season. These findings offer critical insights into the elevational-dependent adaptation of Q. leucotrichophora, which could inform targeted conservation strategies to preserve the species in the face of environmental changes. By aligning conservation efforts with the species adaptive traits, we can manage habitat and prioritize conservation actions, ensuring the suitability of Q. leucotrichophora in the Western Himalayan region.
