A long-standing question in ecology and biogeography is how the population of a species is distributed across space. The highest abundance has been hypothesized to be in the geographical centre or the niche centre, although mixed patterns from empirical studies have triggered a recent debate. Here, we propose a conceptual framework based on environmental suitability and dispersal to interpret the mixed evidence.

使用模拟数据解释扩散可以提高对物种丰度模式的理解

生态学和生物地理学中一个长期存在的问题是一个物种的种群如何在空间中分布。最高丰度被假设在地理中心或生态位中心，尽管经验研究的混合模式引发了最近的争论。在这里，我们提出了一个基于环境适宜性和分散性的概念框架来解释混合证据。
