Abstract

Four species of gymnamoebae isolated from a sandy shore were subjected to hydrodynamic disturbance within microcosms. Increasing the level of disturbance increased the generation times of all four isolates. Generation times of a small Platyamoeba sp. and a limax amoeba were least affected by increasing disturbance. The greatest increase in generation times was observed in populations of two large (>15 μm) Mayorella sp. and Vannella sp. This study shows that hydrodynamic disturbance may be an important community structuring force within natural marine amoebae communities.
