Looking at a time capsule from Twente
By Dobrochna Delsen (currently studying for BSc Biology at the University of Amsterdam)
An unusual early morning.
It is 8:15. My train arrives at Science Park. After a ten-minute walk accompanied by other students I arrive at the university. After a short contemplation about whether I should take the elevator, I decide to take the stairs. The stairs are a bit exhausting, especially since the microscope room is at the top floor, but it gives me the necessary ‘exercise’ for the day. As I walk to the room at the end of the corridor I can see that the coat rack is still empty, except of the one lab coat that hangs there since the day my bachelors project started. I take out my student card and hold it against the door handle. The sound of the unlocking door gives me feeling of satisfaction and power. I step into the empty room with a feeling of superiority and go to my microscope where I will sit for the rest of the day.

This is the first is a series of blog posts based on papers discussed at our “Amsterdam Palaeoecology Club” meetings. The APC meetings are organized to promote palaeoecological discussion and to help the scientific development of our MSc and BSc research students. At each meeting we discuss a paper and the progress of individual projects. Short summaries of the papers and discussions are then made by the student introducing the paper. First up is MSc researcher Rianne van Duinen with her thoughts on Kaplan et al. (2016).

We discussed the paper “Large scale anthropogenic reduction of forest cover in Last Glacial Maximum Europe“ by Kaplan et al. (2016) which was found by the group to be super interesting and it incited a lot of discussion. The paper was mostly concerned with the anthropogenic influences and past vegetation of Europe. The main conclusion was that humans had a very big impact on forests during the last glacial period through the use of fire. The authors suggest that human actions are the explaining factor for the low amount of forests cover suggested by pollen records during the last glacial maximum (c. 21,000 years ago). The suggestion from Kaplan et al. that human modification of forest cover through fire during the glacial links with a recent study from Sevink et al. (2018) that suggests, based on pollen and charcoal data from the Netherlands, that human use of fire altered forest cover into the Holocene. In our discussion it was also noted that animals (mega-herbivores) were not really taken into account or discussed, even though animals probably had a big impact on the vegetation (e.g. see Bakker et al., 2016). Furthermore, another discussion point was the charcoal records that were used in the Kaplan et al. study, more specifically the number of cores. Kaplan et al. only used three cores to map out the effect of charcoal. It would be interesting to see what happens when more data from more cores is used. The Global Charcoal Database has a lot of data on European cores (c. 38% of the cores are from Europe) so there is a lot of potential for this. All in all, the article by Kaplan et al. raised a lot of questions and opened up a nice discussion.
