| description | A 370 cm long sedimentary core was investigated using paleoecological proxies to reconstruct environmental changes
of the meander bend in Pak Nam Pran area, the Malay-Thai Peninsula during the last millenniums. The sedimentary profile can
be divided into four biozones based on their dominant palynomorphs. The Micrasterias zone represents a back swamp on the
floodplain deposited around 1800 years before present (B.P.) until 1,500 years B.P. After that, the younger Ilex zone represents a
swampy area with Ilex trees until 1,000 years B.P. The younger Cyclotella striata zone represents the swampy area near the Pran
Buri riverbank up to 150 years B.P. indicating an ongoing marine regression during the last millennium. The youngest
Rhizophoraceae zone indicates a mangrove forest occurring from 150 years B.P. with seawater intrusions during daily high tides.
Moreover, recent human activities are also recorded within the area indicated by strongly enhanced elements at the top of the
core. |
