I would like to draw readers attention to the “Unissued Diplomas” exhibition that documents stories of students killed in the ongoing war in Ukraine. This exhibition is currently on display in the entrance hall of the Science Faculty building of the University of Amsterdam. You can view the exhibition online at: https://www.unissueddiplomas.org/

Ansis Blaus is a Latvian postdoctoral research associate exploring patterns of climatic and anthropogenic change in the Neotropical Paleoecology Research Group led by Mark Bush at Florida Institute of Technology. He earned his Ph.D. in Earth Sciences from Tallinn University of Technology, Estonia. Supervised by Dr. Triin Reitalu he worked on modern pollen-plant relationships and palaeoecological reconstructions of peatlands and calcareous spring fens with an emphasis on biodiversity and plant functional trait reconstructions.
Currently, at Florida Tech, Ansis works on pollen data and other proxies from the sediment cores collected in the tropical Amazon. He investigates the tropical forest changes in relation to the global climate from a historical perspective, particularly during the Last Glacial Period and the Last Interglacial ca. 130 thousand years ago. His work will shed light on the history of dynamics and climate tipping points in the Amazonian rainforest. This research is particularly important in the face of the current global climate crisis and could help to anticipate the tropical forest response to the changing climate in the future.
Another objective of Ansis’s work is to study the pollen signature of human disturbance in the Amazon Basin as a means to model and interpret human presence and activities in the past and to understand human-nature interactions in tropical forest ecosystems in different spatial and temporal scales. For that, he is collaborating with the University of Amsterdam, Institute for Biodiversity and Ecosystem Dynamics, and working on a project aiming to quantify tropical pollen assemblages led by Crystal McMichael.
Ansis is fascinated by the potential revelations that come with the intersection of neoecology and paleoecology and human interactions. His interest in paleoecology, biodiversity, and various natural processes comes through the sense of pursuing a higher purpose for society and the well-being of our planet, and from the concern that humans have altered tropical forests and most other ecosystems in the world to the level of a negative rebound effect. Ansis believes that we must study and understand these ecosystems from different perspectives to decrease the current damage, predict future scenarios and to develop conservation strategies for both nature and human well-being.

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!
