The Mapping Ancient Africa (MAA) workshop in Rome will take place on the 12 and 13 July 2023. The workshop supported by International Union for Quaternary Research (INQUA) and hosted by the Royal Netherlands Institute in Rome. During the workshop we will be working towards aims of the MAA project to strengthen the research community of Quaternary scientists working across Africa, and to further our scientific goals of understanding past climate change. To achieve this we will work collaboratively to:
Twenty-seven people are registered for the workshop and we look forward to seeing them in Rome. If you are not registered for the workshop but still want to participate this is possible. On the 13 July between 15:00 and 18:00 CEST the workshop sessions will be online via Zoom. To obtain the Zoom link either visit the MAA Slack channel, or contact William Gosling. During the online part of the meeting we will present the outputs from the palaeoclimate mapping activity, the plans for the special issue, and outline the ideas future of MAA. Feedback from the wider MAA community will be very welcome.

Yesterday evening, in my capacity as chair of the exam board MSc Earth Sciences, I had the pleasure of handing out degree certificates to graduates of both our Earth Science and Biological Science programs. It was unusual to have a combined event, but very nice given that I teach on both programs. It was great to meet up with some familiar faces and recount tales from past courses, notably the Field Course “Geoecological Systems”, and the associated adventures in the high Andes, came up a number of times! It was impressive to note the span of the research projects that students had been engaged with; from molecular biology to carbon cycle dynamics, and environmental policy. I think that all concerned had a great time at the ceremony, and throughout their studies at the University of Amsterdam. Congratulations again to all!
If you are interested to also become a happy graduate in a few years time sign up online for programs starting in September 2023:

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.
