对影响原生生物种群，特别是浮游生物的假定生态因素的简要评论。Pearsall对Dinobryon的观察结果与作者未发表的数据以及其他研究人员的发现进行了比较。NO_3：P.PO_4比值的升高或SiO_2浓度的降低，通常与极大甲藻共存。也许在这种情况下和更普遍的情况下，化学因素主要是通过改变物种之间的竞争关系而起作用的，而不是通过直接超越耐受限度而消灭物种。
Brief critical review of supposed ecological factors affecting protistan populations, especially in plankton. Pearsall''s observations on Dinobryon are compared with unpublished data of the author''s, and with the findings of other investigators. A rise in the N.NO3:P.PO4 ratio or a fall in the SiO2 concn. is often concomitant with Dinobryon maxima. Probably both in this case and more generally, chem. factors primarily act by altering the competitive relations between species, rather than by eliminating species through direct transgression of tolerance limits.
