The Use of Palynomorphs as Indication for Environmental Monitoring “Case Study” River nun, Southern Ijaw, Niger Delta
Abstract
Various application of palynology has been used in environmental studies primarily in its application to the study of vegetational history and palynomorphs such as pollen remains, charred plant particles/ tissue, diatom frustules, dinoflagellate cysts, fungal spores were encountered when analyzing palynological preparations. The samples were collected with Modified Auger Sampler using simple technique and analyzed palynologically. The Results of the analysis samples showed a grand total of 4,000 palynomorphs consisting of fungal spores, charred plant tissues, diatom frustules, pteridophyte spores and dinoflagellate cysts. Some of this palynomorphs have been associated with water transport while fungal spores constitute human, animal and plant pathogens with long history of epidemiology. Diatoms and dinoflagellates cysts are useful in palaeoecological species with distinct ecological tolerance and autecological information; and have been implicated in environmental analysis. Charred plant particles serve as measure of bush fire and can be used in monitoring the intensity and frequency of indiscriminate bush burning. The results is anticipated to provide useful insight into climatic and vegetation shift within the context of palaeo-environmental reconstruction which is fresh water marine sedimentary environment, with a diagnostic palynomorphs showing that the paleoecology consists of mangrove with the present of Podocarpus milanjianus diagnostic form of Pliocene.
