Germination was evaluated as successful if an empty cyst wall was found and unsuccessful if the cyst remained intact and did not germinate after the incubation period. WebOct 4, 2024 · Cysts typically germinate from a thin (few millimeters) layer at the sediment surface where there is oxygen ( 26 ), but cysts in deeper layers can contribute to bloom initiation following bioturbation or current-driven resuspension. There is active sediment mixing throughout this region ( 27 – 29 ), so the top 3 cm are tabulated here. imbalance and selectivity bias examples
