“…In this paper we studied dispersed oak pollen from the Holocene deposits, Bray Area Lake, Rolla, Missouri with LM, SEM and TEM. Bray Area Lake is a man-made impoundment located next to a single-family residence and originally created in the 1940s (Haselwander & Oboh-Ikuenobe 2017). Thus, in this case correlations can be drawn between the oak species known for this region and the dispersed pollen in the lake sediment sample.…”

Oak pollen has great potential to be used in reconstructing paleovegetation and paleoclimate. Pollen grains from Holocene sediments of Rolla, Missouri, USA were studied. The goal of this study was to evaluate the morphology of dispersed oak pollen using light and electron microscopy. Three types of oak pollen were recognized: Group 1, Group 2, and Group 3. They occurred in the sample in the following approximate percentage: 52, 32 and 16% respectively. Pollen of Group 1 corresponds to that of white oaks, pollen of Group 2 to that of red oaks. Pollen of Group 3 differs from oak pollen known for the studied region. While electron microscopy shows a good prospect for a detailed interpretation of dispersed oak pollen, many factors should be taken into account when assessing past vegetation: the paleo-forest density, location of sampling, apparent wind direction during pollination, and the “resolving ability” of pollen morphology for different oak species. The intensity of flowering and direction of the pollen transport can significantly influence the quantity of pollen of a particular species in the spectrum. The possibility of medium or long-distance transport of a small quantity of oak pollen from other regions should also be considered in the interpretations of fossil spectra.

Given the increased interest in non-pollen palynomorphs (microscopic objects other than pollen identified from the pollen slides) in palaeoecological studies, it is necessary to seek a deeper understanding how reliable the obtained results are. By combining quantitative information of algal pigments and phylotaxonomical resolution from sedimentary ancient DNA (sedaDNA), we validate the richness and abundance of aquatic non-pollen palynomorphsfossil algae, in the sediment of a small temperate lake. For the first time, fossil and sedaDNA algae data were combined in a composite data-set and algal turnover rates in time were reconstructed for the last 14,500 years. This comparison will serve as an indication to what extent fossil algae can be used to answer different research questions and to reveal if it is reliable to base palaeoecological interpretation solely on fossil algae identified from the pollen slides.
