The June 2023 meeting of the Dutch palynological society (Palynologische Kring) took place at the offices of the Dutch National Cultural Heritage Agency (Rijksdienst Cultureel Erfgoed) in Amersfoort. The focus of this meeting was the past forest landscape of the Netherlands. The meeting included the annual report of the society, three scientific talks, and a prize giving for the best MSc thesis.
The annual report of the society showed a healthy finances and membership (>100 members). Two key events from last year were the award of the societies highest award, the Jongmanspenning, to Margaret Collinson for her massive contribution to the field, and the annual excursion; in 2022 this was to Leiden and included visits to Roman archaeological sites.
The scientific part of the meeting was kicked off my Roy van Beek who presented results from his ongoing project on the peatlands of the Netherlands which suggest peatland expansion occurred between 5500 and 3500 years ago (van Beek et al., 2023). The second talk was by our host, Otto Brinkkemper, and traced the history of woodlands across the Netherlands on the basis of macrofossil finds; including huge tree stumps remarkably preserved in peatlands (Bazelmans et al., 2021; Kooistra et al., 2006). The final talk was given by Jos Bazelmans who showed the remarkably high volume of tree stumps that have been recovered from the Netherlands, and how tree rings from these 100s of record are being used to reconstruct forest histories and past climate change. It was interesting to hear that the average age of the tree stumps found was around 250 years, and that some of the trees had lived to around 400 years in exceptional cases.
The final section of the meeting was the prize giving. Corrie Barkels, on behalf of the independent judging panel, announced Kelly van Leeuwen as the winner for her thesis entitled “Using soils samples and footwear to improve forensic palynology”. Her thesis was conducted at the University of Amsterdam as part of her MSc Earth Sciences degree and was conducted in collaboration with the Netherlands Forensic Institute. Congratulations Kelly!

The next meeting of the Palynologische Kring will take place on the afternon of Tuesday 13 June in Amersfoort. There will be scientific seminars from Roy van Beek (Wageningen University & Research), Otto Brinkkemper (Cultural Heritage Agency), and Jos Bazelmans (Cultural Heritage Agency) focused on the development of the Dutch landscape. In addition the prize for best palynological MSc thesis in the Netherlands – the Florschütz Award – will be given out.

The thirteenth Mapping Ancient Africa seminar was delivered by Andrea Manica on the 18th May 2023. In the seminar Andrea introduced the pastclim R package and gave examples of how it can be applied to address questions related to human evolution and dispersal.
Details of this seminar can be found here. You can find more Mapping Ancient Africa seminar videos on the “Ecology of the Past” YouTube channel.

On Tuesday 16 May 2023 a small team of researchers from the Institute for Biodiversity & Ecosystem Dynamics (University of Amsterdam) visited the Maashorst (Netherlands) to visited an area “re-wilded” with European Bison (Bison bonasus). In addition to the bison the area is also now home to Tauros and Exmoor Ponies The purpose of the trip was to collect soil surface samples to examine for dung fungal spores. Certain fungi grow only on the dung of herbivores and the spores of these fungi can be preserved in the sedimentary record (for more information see Lee et al., 2022). Analysis of dung fungal spore diversity through the sedimentary record can therefore provide insights into the changes in the amount of dung (animals) in the landscape in the past. The purpose of this sampling effort was to see if we can quantify how many, and what type, of spores are representative of this group of bison. This information will help us to be able to interpret ancient records of fungal spores in more detail.
Special thanks to Maurice van Doorn (Gemeente Maashorst) for showing us around.

On Wednesday 11 May 2023 I was delighted to give a online seminar for the African Pollen Database group on integrating palaeoecological data into educational programs. Thanks to Sarah Ivory, Chris Kiahtipes, and Alejandra Domic for inviting me and organizing this series.
I covered topics including the motivation of students, designing a MSc level course, and setting up BSc/MSc research projects. My presentation was centered around my personal experience of running courses for BSc Biology and Future Plant Studies students (Palaeoecology), and for MSc Earth Science and Biological Science students (Environments Through Time) at the University of Amsterdam. It was nice to get a wider perspective from discussion with the audience and to pick up some additional ideas and advice. If you have other thoughts on this topic please feel free to comment on this post.
The entire African Pollen Database online seminar series is now available to watch via the associated YouTube channel. So to find more click here.

In addition to researchers, many of us are also educators! William Gosling (this blog’s esteemed owner) will be leading a discussion of how to use the African Pollen Database (APD) for outreach and education! Please join us Wed, May 10 at 9am EDT (time zone converter). Please email sji15@psu.edu for the zoom link and instructions.
At this workshop, Will is going to focus on:
Do you have exercises and modules that you have incorporated paleoecological data into? If so, we’d love to hear some of your ideas as well!
