Braided river springs: distribution, benthic ecology, and role in the landscape
... Most of the non-insect taxa found in this study are assumed to have low dispersal powers due to the lack of a terrestrial phase in their lifecycles (Malmquist 1991, Milner et al. 2000). For example, the molluscs ...
