Gloeotrichia Echinulata

The quantity and distribution of colonies of Gloeotrichia echinulata migrating from the sediments into the water column were studied in Lake Erken by the use of inverted traps. The epilimnetic population and the phosphorus status of the epilimnetic colonies were quantified. The numbers of colonies in the traps were greatest in the shallower areas. As the stratification became weaker and the epilimnetic population declined, the amount of colonies in all the traps increased markedly. Most of the colonies in the traps were due to redistribution within the water column. On the assumption that no epilimnetic uptake of phosphorus occurred in G. echinulata, the internal loading of phosphorus due to migrating colonies was calculated to be between 0.4 and 0.6 mg P m-2 day-1 during July and August. The proportion of newly migrated colonies in the epilimnetic G. echinulata population was calculated to be around 50% for the period before the epilimnetic population maximum. The increasing phosphorus content of the epilimnetic colonies after the population maximum indicates that the migration continued even after this.
