Palaeoecology course 2023

The pollen and phytolith identification quiz! Is that an Asteraceae phytolith I see…???

The University of Amsterdam “Palaeoecology” course commenced this week with lectures getting students up to speed with the fundamental principles and approaches to the subject, and laboratory practicals training students in the identification of micro- and macro-fossils. Once students have gained a basic understanding of pollen and phytolith identification – and demonstrated this by passing the ‘dreaded’ identification quiz – it is time to commence the group project work.

This year the students are trying to identify from which study site their ‘mystery slides’ come from on the basis of the micro-fossil assemblages (pollen and phytoliths) that they contain. The study sites all come from the area around Hilversum (Netherlands) and (could) include: heathland, pine forest, mix-deciduous forest, and birch woodlands. In addition, just to make it more interesting, one group has samples taken from the medieval palaeosol that is found locally.

Next week is field work week and the students will then need to parameterise the vegetation around the Hilversum area in such a way that they: (i) get a representative sample the variation across the landscape, and (ii) can compare the vegetation data with their micro-fossil data. Then, following the number crunching in the third week of the course, we will find out if the different groups can identify the correct study site from which there samples came…

The Palaeoecology course at the University of Amsterdam is part of the BSc Biology program, it is also frequently taken by students on the BSc Future Planet Studies degree. We also welcome students from other programs, such as BSc Béta-Gamma, and international exchange students.

Introducing Tessa Driessen

Tessa DriessenHi I’m Tessa and really excited to introduce myself here!

I’m an Environmental Biology Master student from Utrecht University (UU) doing a research internship in Amsterdam with William Gosling and Rike Wagner of the UU. Most people would describe me as a typical biologist because I like identifying plants and know some birds by their name. Personally I disagree because I lack the beard and hardly wear woollen socks. Besides looking at birds and plants I’m also interested in biodiversity and palaeoecology, and I will try to combine these interests in my research project on a sediment core from Samoa. I will be working on lake sediment cores from Samoa and hope fossil record can give me an overview of the natural history of the island (past c. 10,000 years); and an insight into what impact human colonisation had on the biodiversity. To explore the islands natural history I will be looking at pollen, charcoal and non pollen palynomorphs.

The sediment core on which I will be working has already been recovered and currently resides in beautiful Southampton (UK). So I’m spared of a 30 hour trip to tropical Samoa and the opportunity to return with some Samoan tattoo’s and a tan… So thanks to David Sear and his team at the University of Southampton with whom I will be collaborating for this project.

I have a long standing interest in tropical islands. Before commencing this research internship I did my first masters internship at WWF Indonesia. For my WWF internship I spent three months in the tropics collecting baseline ecological data on timber companies located in a new reserve in Sumatra. Furthermore, during my bachelor degree, I did a research internship at Naturalis Biodiversity Center investigating the “Correlation between higher altitudes and endemic plant species” in the Malayan archipelago. Our results turned out much better then we hoped for and fingers crossed our article will be accepted soon!

In three weeks I will be starting in the lab in Amsterdam and hopefully in a few months will be able to post an update about my results here.
