Pollen analysis and analysis of sediment organic matter content will provide the paleobotanical information needed to compare the evolution of the terrestrial and aquatic environments, making it possible to verify the timing of the response of past ecosystems to climatic changes.
The diameter and spine length of pollen from these accessions was similar to our measurements, specific to the species, Heslop-Harrison (1968) reported that the patterning in the pollen grain wall in many species is so precise, distinctive, and consistent that it has formed the basis for pollen taxonomy and wall patterning is widely used in geological and paleobotanical analyses (Moore et al.
