Cleaned stones or glass slides placed in streams were quickly colonized by vorticellids and Carchesium, whose numbers increased for about 2 weeks before falling to a steady level by about 4 weeks. Platycola populations developed more slowly, but tended to become dominant after 3 or 4 weeks. The populations of peritrichs on surfaces already coated with 'periphyton' remained at low levels, even after the surface had been disturbed by removal to a new site. Stone surfaces carried higher peritrich populations than glass slides, though Platycola colonized grooves on glass slides to almost twice the density found on the smooth glass surface. Surface irregularities appear to enhance attachment. It is suggested that in general the densities of peritrich colonization are determined by available settlement sites, available food, and predation.
清洗过的石头或玻璃载玻片放置在溪流中，很快就会被涡虫和 Carchesium 殖民，它们的数量在大约 2 周内增加，然后在大约 4 周后降至稳定水平。盘形虫的种群发展得更慢，但在 3 或 4 周后往往会占据优势。已经被“周丛生物”覆盖的表面上的缘毛类种群数量仍然很低，即使表面已经被移到新的地点而受到干扰。石头表面的缘毛类种群数量高于玻璃载玻片，尽管盘形虫在玻璃载玻片的凹槽中殖民的密度几乎是光滑玻璃表面的两倍。表面的不规则性似乎增强了附着性。有人认为，一般来说，缘毛类殖民的密度取决于可用的定居点、可用的食物和捕食。
