“…Cassia fistula is a polleniferous/ nectarless tree species. Pollen grains of Cassia fistula have been reported in honey from various parts of India (Tiwari et al, 2010;Harugade et al, 2016;Tripathi et al, 2017). Citrus was identified as a secondary pollen type in the present study.…”

Eighteen Apis dorsata Fabricius summer honey samples collected from Prayagraj District (Uttar Pradesh) during the summer season were analysed for pollen content. A total of 43 pollen types belonging to 26 plant families were found in these samples. Five of the 18 honey samples were found to be unifloral; 13 were multifloral. In terms of frequency, pollen of Syzygium cumini, Azadirachta indica and Coriandrum sativum were recorded as predominant pollen types, 11 pollen types as secondary pollen types, 23 as important minor pollen types, and 38 as minor pollen types. The Asteraceae family showed the highest frequency of occurrence. Four pollen types were recorded in more than 50% of the honey samples: Ageratum conyzoides, Bombax ceiba, Azadirachta indica and Syzygium cumini. Absolute pollen type counts per 10 g of honey samples ranged from group II to group V. The aim of determining and evaluating the pollen data was to infer the flora visited by the honeybees during the summer season in Prayagraj District. The findings were correlated with the pattern of vegetation in the vicinity of the bee hive sites during honey production. The study indicates that Prayagraj District has good potential for beekeeping ventures, due to the high diversity of nectar- and pollen-producing taxa during the summer season.

“…While some research has been conducted to understand past vegetation and climate history in relation to the paleoherbivory in national parks in tropical regions of the world (Burbridge et al, 2004; Ekblom and Gillson, 2010), little research has been carried out on modern pollen deposition in relation to the different vegetation types in national parks and wildlife sanctuaries in Asia (Basumatary et al, 2014; Bera et al, 2014; Djamali et al, 2009; Ghosh et al, 2017; Pandey and Minckley, 2019; Setyaningsih et al, 2019; Tripathi et al, 2016). These previous studies have often not recorded the presence of coprophilous fungal spores so cannot be used to determine the presence and abundance of herbivorous animals in the region.…”

The main aim of this study is to produce a modern analog for pollen and non-pollen palynomorphs (NPPs) preserved in soil in relation to the different vegetation types and herbivore impact in the Kaziranga National Park (KNP). The pollen data obtained reflects both the extant vegetation types in each habitat as well as landuse, but some site-by-site variation was observed with respect to the coprophilous fungal spores present in the palynoassemblage. Canonical correspondence analysis (CCA) analysis of pollen data reveals the presence of five significantly different vegetation types, while the non-pollen palynomorphs are relatively similar in relation to the different vegetation types. The long-term association of the wildlife and their impact on different vegetation types is one of the main reasons for the variation seen in the depositional pattern in the assemblage. The openland area is one of the most important areas for wildlife in the KNP as indicated by the presence of marker pollen and coprophilous fungal spores in the palynoassemblages. Coprophilous fungal spores were most abundant in this vegetation type reflecting the higher density of herbivores. The representation of pollen and coprophilous fungal spores from the swamp samples reflected the overall composition of all vegetation types existing in the KNP. This data can be utilized as a baseline for the interpretation of paleoecological and paleoherbivory studies in other parts of the Indian subcontinent as well as its potential application at a global level.

“…Taylor and Hu (2010) believed that pollen morphology could help distinguish anemophilous and entomophilous plants in fossil specimens and identify pollen grains carried in insect specimens to infer the origin of the insects (Chang, 2018;Hendrix & Showers, 1992;Liu, Fu, Mao, Xing, & Wu, 2016) and study their flower-visiting behaviors (Chen & Wang, 1998;Wang, 2020;Zhang, Lu, Gao, & Wang, 2002). Moreover, analyses of pollen grains in honeybee samples were used in melissopalynology to explore honeybees' foraging ecology, visiting vegetation, habitat composition, food source changes, and hive geographical location (Ahmad, Zafar, Ahmad, Yaseen, & Sultana, 2019;De Jesus et al, 2015;Devender, Ganga Kailas, & Ramakrishna, 2016;Matos & Dos Santos, 2017;Rasoloarijao et al, 2018;Tripathi, Basumatary, Bera, Brahma, & Sarma, 2017;Ullah et al, 2021). Some scholars believed that pollen morphology is closely correlated with pollination syndrome (Lee, 1978;Stroo, 2000;Taylor & Levin, 1975).…”

In order to provide a palynological guide for the identification of insect-carrying pollen grains, we studied the pollen grains of 10 anemophilous species and 10 entomophilous species in the Beijing urban area using light and scanning electron microscopies. We found that anemophilous pollen grains are small, spheroidal, or oblate spheroidal, while entomophilous pollen grains are medium and oblate. Comparison of the exine thickness and surface ornamentation showed that anemophilous pollen grains have significantly thinner exine and smoother surface ornamentation than entomophilous pollen grains. The results also revealed pollen characteristics adaptive to different pollination types. Overall, our study indicated that pollen morphology might be helpful for preliminary identification of anemophilous and entomophilous pollen.
