Influence of pH on the distribution and abundance of freshwater snails.

We compared snail populations with pH as a limiting factor in two acidic and two alkaline lakes in Northern Michigan. We estimated populations by the depletion method to determine whether the snails differed in abundance and diversity. The two acidic lakes contained no snails as opposed to the basic lakes which had relatively large snail populations. No species overlap existed between these alkaline lakes. We concluded that pH was a limiting factor in snail distribution.https://deepblue.lib.umich.edu/bitstream/2027.42/54335/1/2771.pd
