物种丰度分布的一般模式

自20世纪70年代以来，物种多度分布（SAD）一直是生态学中最基本的问题之一，并经常被调查和审查。然而，令人惊讶的是，几乎没有达成共识。本研究着重于三个基本问题。(1)是否有一个普遍的SAD模式，任何社区都不能违反它？(2)如果它存在，它看起来像什么？(3)为什么会这样？来自8个数据集（包括陆地，水生和海洋生态系统的11个分类组）的19,833个SAD的频率分布表明SAD可能存在一般模式。根据两个假设（总能量的有限性和从熵到多样性的因果关系），本研究假设SAD的一般模式与Zipf定律近似一致，这意味着Zipf定律在研究任何SAD时可能更容易观察到。未来，这一猜想不仅需要越来越多的数据集来检验（或支持），还取决于从不同的理论角度解释得如何。
Since the 1970s, species abundance distributions (SADs) have been one of the most fundamental issues in ecology and have frequently been investigated and reviewed. However, there was surprisingly little consensus. This study focuses on three essential questions. (1) Is there a general pattern of SAD that no community can violate it? (2) If it exists, what does it look like? (3) Why is it like this? The frequency distributions of 19,833 SADs from eight datasets (including eleven taxonomic groups from terrestrial, aquatic, and marine ecosystems) suggest that a general pattern of SAD might exist. According to two hypotheses (the finiteness of the total energy and the causality from the entropy to the diversity), this study assumes that the general pattern of SAD is approximately consistent with Zipf’s law, which means that Zipf’s law might be more easily to observe when one investigates any SAD. In the future, this conjecture not only needs to be tested (or supported) by more and more datasets, but also depends on how well it is explained from different angles of theories.
