Trapped in the web of water: Groundwater-fed springs are island-like ecosystems for the meiofauna.

In the case of the stygobiotic species (Figure 4 d–f), we found a marginally significant correlation between interspring geographical distances and overall species dissimilarity (ßsor, r = .298, p = .046), whereas no correlation was found for the pure turnover component or the nestedness component (r = .123, p = .204 for ßsim and r = .047, p = .367 for ßnest, respectively).
