... with a distinct transition from Difflugia globulus dominance in the lower half of the core to a Difflugia oblonga dominated assemblage in the upper half. D. oblonga prefers organic-rich substrates and its dominance coincides with an increase of organic material in the core. Late Holocene thecamoebian abundance...

... Cucurbitella tricuspis . Strong inverse relationships of cysts of Peridinium willei (R 2 = 0.81) and Difflugia oblonga tests (R 2 = 0.7) with water depth are attributed to variations in bottom water oxygen concentrations. Both ecological and taphonomic factors must be considered when reconstructing...
