My name is Veerle, and I am in my first year of the Master in Biological Sciences, Ecology & Evolution track, at the University of Amsterdam. I also completed my BSc Biology at the University of Amsterdam, specializing in Ecology and Global Change. One of my favorite courses during my BSc was Palaeoecology, which led to a BSc research project with William Gosling and Crystal McMichael on the farming history in the Netherlands. I really enjoyed this project and it made me even more interested in palaeoecology. This year I have gotten the amazing opportunity to do another project with Crystal McMichael…. including a field expedition together with Britte Heijink and Nina Witteveen to Panama and Colombia! This was an amazing experience with a lot of fun, mud, insect repellent and most of all really nice cores! I am super excited to tell you about my field experiences, so soon we will post another blog about that!
Collecting the soil
Now that we’re back in Amsterdam, I’m analyzing phytoliths from Gigante (Panama) to reconstruct the fire and vegetation history. I’m especially interested in past agriculture and forest management to see if there were humans present in the area and how they affected the vegetation. Hopefully I can show you some nice results about that in the future!

My name is Britte Heijink and I’m doing my MSc Biological Science thesis research project with Crystal McMichael and William Gosling. I travelled with Veerle Vink and Crystal to the Colombian part of Amazonia to collect samples for my project. At Amacayacu National Park, we collected soil cores from different locations in the plot. Now that we’re back in Amsterdam, I’m analysing the soils to reconstruct the fire and vegetation history from the plot using charcoal and phytoliths. I am specifically looking to see if humans have been present in the system and how they potentially affected the vegetation at Amacayacu.

I’ve completed my bachelor thesis for Bèta-Gamma (Liberal Arts and Sciences) under the supervision of Crystal and Will here at the UvA. I’m really excited to work with them again, and already looking forward to our meetings at the Oerknal 😉 I will be finished by the end of September, and then possibly return for a literature study.
One of the most wonderful experiences in my academic career so far has been the fieldwork to Panama and Colombia with Crystal, Veerle, and Nina. It was a lot of hard work, and 90% of our time was spent covered in mud, sweat, and insect repellant, but the experience of working in a tropical rainforest was completely worth it! Veerle and I will write another blog about our fieldwork soon. Come see us in the microscope lab if you want to hear our dangerous and amazing stories before that!
Our last day in the Amazon was spend with some of the local students, Louisa Fernando Gomez Correa and Mariana Gutierrez Munera.
Researchers in the Institute for Biodiversity and Ecosystem Dynamics (IBED) at the University of Amsterdam have been studying the páramos and Andean ecosystems for over 50 years. These highly diverse ecosystems are currently restricted to mountain-tops (resembling an archipelago of islands in the sky), but in the past dominated large surface areas throughout the Northern Andes. Climate change determined the degree of páramo fragmentation and connectivity in the past, and site-specific results have been integrated into a GIS-environment (visualization) for southern Colombia and the entire Northern Andes by IBED researchers Suzette Flantua and Henry Hooghiemstra.
