Abstract

The Importance of the Regional Species Pool

The regional species pool—the set of species capable of entering a local community—is a foundational concept for understanding ecological processes that occur between local and extensive (biogeographic) spatial scales. However, the lack of precise definitions for the regional species pool, coupled with limited research into the dynamics of regional biodiversity, has impeded the development of a comprehensive framework to explain the mechanisms shaping these pools.

Processes Governing Regional Species Pools

Although ecological processes at local and extensive scales are relatively well understood, the mechanisms shaping regional biota remain less clear. Regional species pools are likely shaped by a unique set of processes that often overlap minimally with those operating at local or extensive scales. Despite their significance, our understanding of the specific mechanisms driving the dynamics of regional species pools remains incomplete.

The Need for a Theory of Regional Species Pools

We argue that it is essential to prioritise the study of the regional species pool for two reasons. First, the regional species pool bridges spatial and temporal scales from ecological dynamics in landscapes to the long-term processes shaping the biotas of entire biogeographic provinces. As such, understanding the dynamics of species pools addresses fundamental questions about the origin, maintenance, and dynamics of biodiversity. Second, effective biodiversity conservation in the Anthropocene hinges on understanding the processes that operate at regional scales.

区域物种库的出现与动态

区域物种库——能够进入当地群落的物种的集合——是理解发生在局部和广泛（生物地理）空间尺度之间的生态过程的基础概念。然而，缺乏对区域物种库的精确定义，加上对区域生物多样性动态的研究有限，阻碍了解释这些物种库形成机制的综合框架的发展。虽然在局部和大范围尺度上的生态过程相对较好地理解，但形成区域生物群的机制仍然不太清楚。区域物种库可能是由一组独特的过程形成的，这些过程通常与在局部或广泛尺度上运行的过程重叠最少。尽管它们具有重要意义，但我们对驱动区域物种库动态的具体机制的理解仍然不完整。区域物种库理论的需要我们认为，优先研究区域物种库是至关重要的，原因有两个。首先，区域物种池连接了从景观生态动态到整个生物地理省生物区系形成的长期过程的时空尺度。因此，了解物种池的动态解决了有关生物多样性起源、维持和动态的基本问题。其次，人类世中有效的生物多样性保护取决于对区域尺度上运作的过程的理解。

期刊介绍： Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
