Vegetation responses to late Holocene climate changes in an Andean forest By Klaas Land (currently studying MSc Biological Sciences (Ecology & Evolution) at the University of Amsterdam.
The discussion during the APC meeting on the 19th of March was on the paper by Schiferl et al. (2018), a very recent study on the climatic shifts in the late Holocene and their effects on the South American tropics. The study had analysed a core going back about 3800 years from Lake Palotoa, which was in the Andean foothills (1370m elevation). They found that subtle changes to the fossil pollen record could be identified around the estimated periods for the Little Ice Age (LIA) and Medieval Climate Anomaly (MCA). The focus in the paper Continue Reading

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 Nina Witteveen and I’m doing a research project for my master (Biological Science) with Crystal McMichael and William Gosling. I’m analyzing phytoliths to reconstruct the vegetation changes of Campo Libre (Napo, Ecuador) of the past 30,000 years. It is so exciting to count phytoliths of such an old age!
Simon Scholz is currently doing a charcoal analysis and two years ago, Maaike Zwier performed a physical analysis in the sediment. With all these results combined, I will investigate how climate changes and human influence have changed the vegetation of Campo Libre. Hopefully this research will give more insight into the effect of a changing climate on this biodiversity hotspot!
I’ve completed my thesis for the Biology bachelor at the UvA under the supervision of Crystal and Will. Together with other students we performed phytoliths, pollen and charcoal analysis from sediment of Well-Aaijen (Limburg, the Netherlands). More specifically, I’ve looked at the vegetational changes during the transition from hunter-gatherers to farmers through pollen and phytolith analysis. I’m very happy to be working with Crystal and Will again, this time in a more tropical setting!
In January of this year, I travelled to Panama with Veerle Vink, Britte Heijink and Crystal McMichael. It was a great experience! Surrounded by Howler Monkeys, we made our way through streams and Geonoma palms to collect soil surface samples for future phytolith analysis. Definitely a highlight of my fieldwork so far! I am now back in the microscope lab, and always up for a (paleo)chat 🙂
