From: Dynamics of natural populations of the dertitivorous mudsnail Potamopyrgus antipodarum (Gray) (Hydrobiidae) in two interconnected Lakes differing in trophic state

Figure 2

Relative distribution of P. antipodarum over depth in meso-oligotrophic lake I and eutrophic lake II. Depth in m. Snail abundances (grey areas) are presented as the percentage of the total number collected monthly (indicated by the numbers) to allow comparison of the relative distribution between meso-oligotrophic lake I and eutrophic lake II, in which the grey area accounts for 100% of the sampled time frame for each lake.
