“…Representativeness differences between pollen and phytoliths to different plant taxa agree with previous calibrations in the same or adjacent bioclimatic zones (e.g., Sun et al, 2016 ; Jiang et al, 2020 ; Fang et al, 2022 ). Pollen-vegetation relationship calibrations have found that R values of the Pinus , Castanopsis , and Dicranopteris pollen (or spores) are greater than 1 (R is the representativeness of a given pollen type, cf .…”

“…In contrast, as most arboreal phytoliths are produced in the leaves of the trees in subtropical evergreen forests, the under-representation of arboreal phytoliths to trees is not surprising ( Piperno, 1988 ; Wang and Lu, 1993 ). Future additional calibrations are needed to address the representativeness differences between arboreal and herbaceous phytoliths, as has been done in palynology (e.g., Sun et al, 2016 ; Jiang et al, 2020 ; Fang et al, 2022 ). Regardless, relative abundances of arboreal and grass phytoliths varied consistently with natural vegetation changes along the elevation gradient, suggesting that phytolith assemblages might be a useful tool for quantitative vegetation reconstruction.…”

“…Pollen-vegetation relationship calibrations have found that R values of the Pinus , Castanopsis , and Dicranopteris pollen (or spores) are greater than 1 (R is the representativeness of a given pollen type, cf . Davis, 1963 ), indicating that those pollen and spore types may significantly over-represent their occurrence in subtropical forests (e.g., Sun et al, 2016 ; Jiang et al, 2020 ; Fang et al, 2022 ). This explains why the percentage of Pinus pollen was greater than 40% in broadleaf forest plots despite the almost total absence of Pinus species in those communities ( Table 1 and Figure 7A ).…”

“…The mismatch between the vegetation inventory and the topsoil pollen assemblage might be linked to the vertical transport of pollen ( Qiu, 1993 ), causing additional complexities in interpreting the topsoil pollen assemblage accurately. Besides vertical transportation, topsoil pollen might be subject to selective preservation; thin-walled taxa may be destroyed during taphonomic processes resulting in lower percentages, while pollen taxa with thicker walls may survive and therefore accumulate in a comparably higher percentage ( Mander and Punyasena, 2018 ; Chevalier et al, 2020 ; Fang et al, 2022 ). As a result, changes in the relative abundance of pollen assemblages may reflect taphonomic processes, rather than ecological factors ( cf .…”

For phytoliths, the aeolian transportation and selective preservation that is quite common for pollen, have less impact on soil phytolith assemblages.…”

This study investigates the reliability of phytolith assemblage analysis for characterizing subtropical vegetation and explores the potential for using these modern phytolith–vegetation relationships for paleoenvironmental interpretation in southeastern China. The samples were collected from five common subtropical vegetation communities in the Daiyun Mountains, southeastern China, with the above-ground vegetation recorded at each plot. Constrained ordination analysis was used to determine the most important factor governing the variations in phytolith assemblages that could be quantitatively reconstructed with weighted averaging partial least squares regression (WAPLS). The relationship between modern phytolith assemblages and the parent vegetation, as well as production, dispersal, and taphonomic processes, was discussed. Results demonstrated that the main subtropical biomes in southeastern China could be well distinguished by soil phytolith assemblages. In particular, the overall amount of tree coverage was well represented by topsoil phytolith assemblages. Grass silica short cell phytoliths (GSSCP) tended to occur in higher proportions in open habitats (shrub-meadow) at higher elevations, whereas non-grass phytolith morphotypes attained higher frequencies under mixed and broadleaf forests at lower elevations. Human-induced deforestation might increase the frequency of GSSCP within the bulk phytolith assemblage. Our results constitute the primary phytolith reference data for the subtropical zone in southeastern Asia where vegetation change during the Holocene period, particularly forest shifts, anthropogenic deforestation, and early agriculture are poorly documented.

Characterising the vegetation-pollen signal is a crucial task for enhancing the interpretation of fossil pollen records. This study analyses 28 surface soil samples collected in the surroundings of Iztaccíhuatl volcano, between 2,650 and 4,024 m asl. Pollen zones and ordination analysis were assessed to establish a qualitative connection between the pollen signal and the distribution of plant communities along the elevation gradient. The results show: (i) the predominant pollen type in the pollen assemblage is Pinus; (ii) pollen grains of Quercus and Alnus are present along the elevation gradient, even at high elevations where the parental plants are not typically found; (iii) samples taken between 2,650 and 3,338 m asl., where fir forests dominate, exhibit higher values of Abies pollen compared to samples above 3,405 m asl.; (iv) the locally-dispersed pollen of the hemiparasite Arceuthobium results key in identifying the presence of pine forests; and (v) pollen taxa such as Apiaceae, Eryngium, Valerianaceae, and Caryophyllaceae are linked to higher elevations, specifically where the plant communities of Pinus hartwegii and alpine grassland occur. The study suggests that the pollen signal along the elevation gradient is useful to characterise the main plant communities of the study site (fir forest, pine forest and alpine grassland). Additionally, the percentage variations of Abies in the pollen signal below 3,600 m asl. show the reduction of fir forest communities resulting from recent human activities in the area.
