A comparative study of pollen morphological characters of 19 species of Combretaceae from Nigeria was undertaken with a view to obtaining additional characters for adequate identification and classification of the taxa. Pollen samples were acetolysed and investigated under light microscope. Hierarchical cluster analysis was employed to show the sim...

Modern surface analogue dataset combining biotic and abiotic proxies (i.e., pollen, phytolith, diatom, stable carbon and nitrogen isotopes of organic matter, soil geochemical and textural parameters together with magnetic susceptibility) were generated from the Ghaghara-Gandak and Ganga-Ghaghara interfluves of the Central Ganga Plain (CGP) to deter...

Accuracy of vegetation reconstruction portraying land cover of the past is based on a careful analysis of pollen production, dispersal and their quantitative deposition. The present attempt to integrate sampling of pollen–vegetation spectrum through Crackles Protocols for vegetation surveys, at three spatial zones with intervals of 0–10 m (A), 10–1...

The present study attempts to understand the geomorphic response in the upper Ganga catchment to the mid-late Holocene (neoglacial) climate variability. The study infers five major phases of millennial-scale climate variability with centennial-scale inversions using geochemical and magnetic proxies from relict Lesser Himalayan Lake sediments. Phase...

This paper presents the first modern pollen, non-pollen palynomorphs and grain size data from a pristine mangrove tidal creek on the South Andaman Island, Andaman and Nicobar Islands, India. The surface sediment samples were collected from different mangrove environments of the Wright Myo Creek, South Andaman to study the relationship between the p...

The relict intertidal deposits from the Kharod River Estuary, Gulf of Kachchh, and the distal end of Kori Creek are used to infer the Mid-to Late Holocene relative sea-level (RSL) change in western India. Employing sedimentology, geochemistry, palynology, ichnology, and optical and radiocarbon dating, the study suggests the dominance of fluvial act...

The Holocene evolution of the Krishna Delta was inferred using landform characteristics and 11 sediment cores with 59 Accelerator Mass Spectrometry ¹⁴C dates. The landform assemblages in a 5880 km² area of the Krishna Delta indicate an upper (landward) river-built fluvial plain and a lower (seaward) marine-built beach-ridge plain. Holocene sediment...

The Holocene sea-level history of the east coast of India is relatively unexplored. We analysed a 17.37-m-long sediment core from Kolleru Lake, a fresh waterbody located in a deltaic setting along the east coast of India, to reconstruct the climate, environmental, and sea-level history of the region. Sedimentary facies and pollen assemblages, with...

Unlike Glacial- Interglacial periods, the Holocene period is seldom known for any drastic climate and sea level changes and thus has been a prime focus for investigating the interplay land-sea level vacillations. Sea level has fluctuated more or less at the present level during mid-Holocene Period and hence local sea level variability should be con...

We present the results of sediment texture, δ13C values, TOC, TN, TOC/TN, and magnetic susceptibility (χlf) of a 1.54-m deep sediment trench recovered from the core monsoon zone (CMZ) of central India, to understand the paleovegetational history and Indian summer monsoon (ISM) variability during the Holocene. The lower δ13C values, TOC/TN ratio, an...

Modern pollen–vegetation studies are crucial for the calibration and interpretation of fossil pollen assemblages. In eastern India, knowledge regarding the relationship between pollen deposition and the modern-day vegetation is required to make use of fossil pollen data, which is still scant. To fill this gap, the present study deals with the polle...

Thirty surface samples collected from the Pakhiralaya area, south-western Ganges-Brahmaputra Delta, India, have been analysed for pollen in order to investigate modern pollen-vegetation relationships. Data on non-pollen palynomorphs (fungal spores, dinoflagellate cysts and algal cysts) were also obtained. There is currently a paucity of modern poll...

The palynological studies of a sediment core collected from the northeastern region of the Chilka Lagoon, reveal the history of mangrove vegetation during the last 4165 yrs BP The Chilka Lagoon (a Ramsar Site) is one of the ecologically and socio-economically important wetlands situated in the humid tropical climatic zone along the east coast of In...

In the present investigation, an attempt has been made to evaluate modern pollen-vegetation relationship in the surface sediments of the Chilka Lagoon, Odisha. The ecosystem of the Chilka Lagoon has remained unique throughout its existence and the data generated from the analysis of surface sediments can be used for the interpretation of palynologi...

Bangladesh has a unique hydro-geological setting and deltaic floodplain which is jointly formed by the deposition of the Ganges (Padma), Brahmaputra (Jamuna) and Meghna River. The physical characteristics of the geographic location, river morphology and the monsoon climate render Bangladesh highly vulnerable to natural disasters, primarily, floods...

Studies on modern pollen deposition are important for understanding the relationship between pollen assemblages and the vegetation from which they are derived. In the present study, 30 surface samples collected from different sites of South and Little Andaman Islands were palynologically analysed to determine the composition of pollen deposited on...

The air-borne pollen grains and fungal spores, the main biocomponents of air are found responsible for the causation of respiratory disorders in sensitive individuals. The air-monitoring in relation to flowering periods, mode of pollination, qualitative and quantitative assessment of bioaerosols are the prerequisites for allergists to identify the...
