A suite of three digenean eel specialist species occurred in all three lagoons, of which any two members dominated each community.
These probably functioned to regulate the rate and timing of seasonal inundation and subsequent drainage of the lagoon and adjoining fields.
This trend reflects the emergence of a new political center among the lagoon settlements.
The incubation bottles were then removed, and the samples rinsed several times with washes of ' cold ' lagoon water.
Excavation of lagoon canals shows their original depth and the depositional patterns that have developed since the abandonment of the canal system.
The situation with respect to eels from coastal lagoons is less clear.
Mangroves are a special group of plants colonising estuaries, deltas, lagoons and coasts.
Flooding would then allow planting in the elevated areas along the seasonal lagoon's edge and on top of the broad dams.
