摘要

更好地了解环境梯度上的生物多样性-生产力关系(BPRs)对于有效的生态系统管理和生物多样性保护至关重要。压力-梯度假说认为,与更有利的条件相比,压力环境中的生物多样性-生产力关系更强。然而,人们对 BPRs 沿海拔梯度的变化及其在不同地貌中的普遍性了解有限。为了研究 BPR 如何随海拔高度而变化,我们利用了温带欧洲和亚热带亚洲山地森林中 152 个地块的 6431 棵树的库存数据,这些数据每隔八到十年调查两次。我们量化了地上生产力与不同生物多样性指标之间的关系,包括分类、功能和系统发育多样性。为了阐明BPR的基本过程,我们研究了不同功能特征在不同地貌上随海拔高度的变化。我们发现,不同地貌和海拔的 BPRs 没有普遍的模式。在温带森林中,所有生物多样性指标的关系都是中性的,而在亚热带森林中,分类和功能多样性的关系则是负的。分类学、功能和系统发育多样性之间的生物变异系数基本一致。我们发现压力梯度假说仅得到微弱支持,在亚热带森林中,BPRs 在接近树线时由负转正(影响不显著)。然而,在温带森林中,海拔模式受到物种特征效应的强烈调节,并受到特定性状的影响。群落加权最大植株高度平均值和木材密度等性状对生产力的影响在不同地貌中是一致的。我们的研究强调了生物生产力指标在不同海拔梯度和地貌条件下的环境依赖性。物种性状是生物生产力因子的关键调节因素,在研究生物多样性的功能作用时应更明确地加以考虑。此外,我们的研究结果突出表明,在保护生物多样性和提高生态系统生产力之间存在潜在的权衡,这需要在政策和管理方面给予更多关注。

No generality in biodiversity-productivity relationships along elevation in temperate and subtropical forest landscapes

An improved understanding of biodiversity-productivity relationships (BPRs) along environmental gradients is crucial for effective ecosystem management and biodiversity conservation. The stress-gradient hypothesis suggests that BPRs are stronger in stressful environments compared to more favorable conditions. However, there is limited knowledge regarding the variation of BPRs along elevational gradients and their generality across different landscapes. To study how BPRs change with elevation, we harnessed inventory data on 6,431 trees from 152 plots surveyed twice in eight to ten year intervals in mountain forests of temperate Europe and subtropical Asia. We quantified the relationship between aboveground productivity and different biodiversity measures, including taxonomic, functional, and phylogenetic diversity. To elucidate the processes underlying BPRs, we studied the variation of different functional traits along elevation across landscapes. We found no general pattern of BPRs across landscapes and elevations. Relationships were neutral for all biodiversity measures in temperate forests, and negative for taxonomic and functional diversity in subtropical forests. BPRs were largely congruent between taxonomic, functional and phylogenetic diversity. We found only weak support for the stress-gradient hypothesis, with BPRs turning from negative to positive (effect not significant) close to the tree line in subtropical forests. In temperate forests, however, elevation patterns were strongly modulated by species identity effects as influenced by specific traits. The effect of traits such as community-weighted mean of maximum plant height and wood density on productivity was congruent across landscapes. Our study highlights the context-dependence of BPRs across elevation gradients and landscapes. Species traits are key modulating factors of BPRs and should be considered more explicitly in studies of the functional role of biodiversity. Furthermore, our findings highlight that potential trade-offs between conserving biodiversity and fostering ecosystem productivity exist, which require more attention in policy and management.

期刊介绍: Forest Ecosystems is an open access, peer-reviewed journal publishing scientific communications from any discipline that can provide interesting contributions about the structure and dynamics of "natural" and "domesticated" forest ecosystems, and their services to people. The journal welcomes innovative science as well as application oriented work that will enhance understanding of woody plant communities. Very specific studies are welcome if they are part of a thematic series that provides some holistic perspective that is of general interest.
