本研究は、パキスタンの落葉樹、常緑樹、混交林において、機能的優占性と機能的多様性が土壌肥沃度や気候とどのように相互作用して地上部バイオマスを調節するかを、一般化線形モデルと機械学習を用いて解析した。その結果、バイオマスは主に機能的優占性と土壌肥沃度によって決まり、気候要因は限定的に影響し、混交林が最も高いバイオマスを示した。これらの知見は、資源制約下での森林管理による炭素固定の向上に役立つ。

This study analyzes how functional dominance and diversity interact with soil fertility and climate to regulate aboveground biomass in deciduous, evergreen, and mixed forests in Pakistan using GLM and machine learning. Biomass is primarily driven by functional dominance and soil fertility, with climate having secondary effects; mixed forests show highest biomass. Findings inform forest management for carbon sequestration in resource-limited landscapes.

📄 Abstract（原文）
Understanding the mechanisms driving aboveground biomass (AGB) variation in forest ecosystems is essential for biodiversity conservation and climate-change mitigation, particularly in environmentally heterogeneous and resource-limited regions. Drawing on community assembly theory and trait-based ecology, this study examines how functional dominance and functional diversity interact with soil fertility and climate to regulate AGB across deciduous, evergreen, and mixed forest stands in Pakistan. Using a combination of generalized linear modeling and machine-learning approaches, we found that AGB is primarily structured by functional dominance, with soil fertility exerting an additional but secondary influence. Climatic factors generally constrained biomass accumulation, although their importance varied among forest stand types. Functional diversity played a comparatively minor role. Forest stand type further modulated these relationships, with mixed forests supporting higher biomass and exhibiting the strongest influence of dominant functional traits, while climate effects were more pronounced in evergreen forests and negligible in mixed stands. Overall, our findings indicate that in resource-limited forest ecosystems, biomass accumulation is governed more by the dominance of particular functional strategies and soil resource availability than by functional diversity or climate alone. Integrating plant functional traits and soil conditions into forest management and restoration strategies may therefore enhance biomass productivity and carbon sequestration in heterogeneous landscapes.
