“…However, Madhuca indica and Sapotaceae have been recorded with 37% and 8% pollen owing to good preservation of their pollen in the sediments and high pollen dispersal efficiency. The high representation of Madhuca indica and Sapotaceae has also been recorded from the study of surface samples from Sapna Lake, Betul District (Chauhan & Quamar 2012). However, Madhuca indica, Holoptelea, Lannea coromandelica, Emblica officinalis, Terminalia, are also recorded in moderate values from Khedla Quila Lake samples (Quamar & Chauhan 2013b), whereas Sapotaceae Schrebera and Sterculia are sporadic.…”

“…In the science of Quaternary palynology, this type of study has been given various names such as modern pollen-rain studies, modern pollen deposition patterns, modern pollenvegetation relationships, etc. In some advanced literature, the study has been given the name of Response Transfer Function as it serves as a modern analogue for the accurate explanation of the pollen sequences generated from the sedimentary beds in terms of past vegetation and climate in chronological order in the region during the Quaternary Period, especially the Holocene and/or Late Pleistocene epochs (Quamar & Chauhan 2012Chauhan & Quamar 2012a. So far as the relationship between the present-day set-up of vegetation and pollen assemblages is concerned, it is not straightforward.…”

“…Bera Palynology 149 one is limnolite which is rich in iron whilst the other is bauxite rich in aluminium (Joseph 1963). Most of the area is under the cultivation of conventional crops such as wheat, paddy, pulses, sugarcane, etc., and is inhabited by Gonds, Bhils, Oraons, Korkens, Kols, Baiga and Panika tribes (Quamar & Chauhan 2012). The Vindhyan Group of rocks and the Deccan Traps in the central sector of the Narmada Valley form the basement for the Quaternary deposits in the area of investigation.…”

The present communication reviews the pattern of modern pollen-rain studies carried out in southwestern Madhya Pradesh, India. The study largely revealed that Tectona grandis (teak), despite being an enormous pollen producer (7500 average number of absolute pollen/flower) and the dominant forest constituent (80 to 95% of the total forest constituents), is recorded mostly in low frequencies, attributable to its low pollen dispersal efficiency as well as poor pollen preservation in the sediments. However, Madhuca indica (Mahua) and other dominant members of Sapotaceae (cf. Manilkara hexandra and Mimusops elangi) have always shown their typical behaviour in the pollen spectra and are represented in high frequencies, which are assigned to their local abundance around the provenance of the samples, coupled with high dispersal efficiency as well as good pollen preservation in the sediments. Meanwhile, the other usual and characteristic associates of teak (Tectona grandis) in the tropical deciduous forests, despite being the common elements of the forests, are under-represented, sporadically represented or not represented at all, which could be ascribed to their low pollen productivity owing to entomogamy. Various factors that affect the deposition pattern of the diverse constituents of the tropical deciduous forests dominated by teak (Tectona grandis) have been discussed and suggestions are also given while interpreting the pollen sequences generated from the sedimentary beds in terms of past vegetation and climate in a chronological order in the region during the Late Quaternary Period.

Non-pollen palynomorphs comprising algal remains, namely Botryococcus, Chara, Concentricystis, Pediastrum, Spirogyra and Zygnema as well as fungal spores such as ascospore types, Alternaria, Cookeina, Curvularia, Diplodia, Glomus, Helminthosporium, Nigrospora, Microthyriaceae and Tetraploa, well identified from the palynoslides prepared basically for the study of palaeovegetational succession and palaeoclimatic reconstructions, are discussed and illustrated from the late Quaternary sediments collected from southwestern Madhya Pradesh (India), which is regarded as one of the core monsoon zones of the Indian subcontinent. Botryococcus and zygospores of Zygnemataceae indicate warmer climate. PediastrumBotryococcus alternation may reflect colder -warmer climates. Botryococcus and Pediastrum may also suggest oscillations in atmospheric precipitation. They could be sensitive indicators of salinity, pH, temperature and depth changes in palaeolagoons influenced by sea-level oscillations and climate. Chara points to less oxygenated and hard water conditions. The record of fungal spores advocates the prevalence of a humid climate.

“…The available information on pollen rain-vegetation relationships from these regions has provided a valuable tool for the accurate appraisal of past vegetation scenarios, which also reflect the climatic changes during the late Quaternary (Chauhan 1995(Chauhan , 2000(Chauhan , 2002(Chauhan , 2004(Chauhan , 2005Chauhan et al 2001;Yadav et al 2004;Shaw et al 2007;Patnayak et al 2009;, 2012a, 2012bQuamar & Chauhan 2011a, 2012, 2014. Hence, in the present study, we investigated how the present-day vegetation in the tropical deciduous forest is represented in pollen spectra of surface samples and moss polsters.…”

The present paper analyses the pollen deposition pattern in a swampy area of tropical mixed deciduous forest at the Baikunthpur Forest Range in the Koriya District of Chhattisgarh, India, based on the palynological investigation of surface samples. The palynological assemblages revealed the dominance of non-arboreal pollen taxa (NAPs: herbs) over the arboreal pollen taxa (APs: trees and shrubs). Among the arboreal taxa, trees constitute on average 41.92% of the pollen in the total pollen rain, whereas the average contribution of shrubs is only 2.19%. Among the herbaceous taxa, Poaceae (grasses) has a relatively high frequency (average 38.20%). The NAPs, on the whole, constitute on average 53.51% of the pollen in the total pollen rain. Cerealia, Chenopodiaceae/Amaranthaceae, Caryophyllaceae, Brassicaceae, Artemisia and Alternanthera reflect the agrarian activities in the study area. Cyperaceae and other marshy taxa represent boggy places around the sampling site and Typha, Lemna, Potamogeton and Nymphoides the aquatic vegetation. Pinus, Cedrus, Picea and Alnus occur in low frequencies and are exclusively wind transported from the Himalayas. Trilete fern spores and lycopods are indicative of humid climatic condition.
