越来越多的证据表明,α多样性对生态系统功能具有积极影响。我们在此强调β-多样性的关键作用-生物多样性的一个迄今尚未充分探索的方面-以更好地理解生物多样性变化及其对生态系统的影响。对β-多样性的关注有可能改善对自然和人为影响多样性和生态系统功能的预测。然而,连接的原因和生物多样性变化的后果是复杂的,因为在自然界中的物种组合是由许多因素同时,包括干扰,环境异质性,确定性生态位因素,和随机性。由于变异性和变化在生态系统中无处不在,承认自然的这些固有特性是在理论和实践中进一步推进生物多样性生态系统功能科学知识的重要一步。
Evidence is increasing for positive effects of α-diversity on ecosystem functioning. We highlight here the crucial role of β-diversity – a hitherto underexplored facet of biodiversity – for a better process-level understanding of biodiversity change and its consequences for ecosystems. A focus on β-diversity has the potential to improve predictions of natural and anthropogenic influences on diversity and ecosystem functioning. However, linking the causes and consequences of biodiversity change is complex because species assemblages in nature are shaped by many factors simultaneously, including disturbance, environmental heterogeneity, deterministic niche factors, and stochasticity. Because variability and change are ubiquitous in ecosystems, acknowledging these inherent properties of nature is an essential step for further advancing scientific knowledge of biodiversity–ecosystem functioning in theory and practice.
