Figure 9From: A comparative study of shell variation in two morphotypes of Lymnaea stagnalis (Mollusca: Gastropoda: Pulmonata) Relationships between geographical latitude and mean SH in the morphotypes L . fragilis (left) and L . stagnalis (right) in Western Siberia. Each point corresponds to a mean SH in a particular habitat. Statistics for regression equations is given in Table 4.Back to article page
