Telford et al. (Brevia, 19 May 2006, p. 1015) reported that freshwater diatoms exhibit regional-scale richness-pH relationships that depend substantially on regional habitat availability. On this basis, the authors argued that, despite their microscopic size, diatoms are not ubiquitously dispersed. Here, I describe my demonstration that their primary evidence against the ubiquitous dispersal hypothesis is spurious.
特尔福德等人（《快报》，2006年5月19日，第1015页）报道称，淡水硅藻呈现出区域尺度的丰富度与pH值的关系，这种关系在很大程度上取决于区域栖息地的可利用性。基于此，作者认为，尽管硅藻体型微小，但它们并非普遍分布。在此，我描述了我的论证，即他们反对普遍分布假说的主要证据是虚假的。
