Dinoflagellate cyst production was low during this brackish interval.
Genuine brackish water parasites are difficult to distinguish from marine parasites.
The soils in the forested areas are characterized by having poor drainage and brackish waters, and are covered by a thick layer of peat.
Mangroves only exist in brackish regions, savannas exist as scattered islands within the forest, and morichal is confined to swamps, streamsides and lake shores.
Dissolved particulate matter in brackish water leads to a predominant reflection of the longer wavelengths, resulting in a reddish hue to the water.
This species is thus well adapted for living in islands where only brackish water is present.
Parasites which infect only 1 host in marine or fresh water, infect several host species in brackish habitats.
In these brackish lagoons, maximum prevalence and lumen worm intensities occur each year in early summer (unpublished results).
