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

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.
I am sitting on the shore of Lago Condorcillo in Southern Ecuador, after a long day of travel, trying to control my shivering. At roughly 10,500 ft. above sea level, the lake is very cold, with wind that howls over the barren hills dotted with giant boulders. The lake is also almost always blanketed by thick fog and pelted by driving rain. When you’re surrounded by the thick fog punctuated by lightning bolts, it’s easy to believe that some lost civilization lurks just out of sight. Tonight we are experiencing lightning storms, which is adding to the feeling that some angry, ancient life form must live at Lago Condorcillo.
Tomorrow, I will be out in the cold and rain, balancing on an inflatable boat and fighting frostbite. Mark Bush, who is my Ph.D. advisor, Courtney Shadik, who is my lab partner and tent buddy, and I will be collecting cores of mud from the bottom of Condorcillo. We will create our rig for coring by tying two inflatable boats together, and placing a wooden platform between them. Mark, Courtney, and I will then collect our mud cores from this platform.
As I’m contemplating the hazards of camping in a lightning storm, Mark says, “Tell me everything that went wrong today.” Courtney pulls a sleeping bag closer to her. I begin to describe how Google Maps can’t seem to understand distance in the Andes, and so traveling to Lago Condorcillo took much longer than we anticipated. Courtney laughs beside me and adds, “We don’t have any matches to start a fire.” Despite our troubles, I am grinning from ear to ear, no doubt spoiling the grim mood Mark is attempting to cultivate and Lago Condorcillo is doing its best to enforce.
We are currently looking for a new representative to join the British Ecological Society (BES) Education and Careers Committee (ECC) of which I am currently the chair. I have been involved with the BES for may years first attending a conference in 2000 (Warwick University), running the Tropical Ecology special interest group (2006-2009), as an ordinary member of council (2010-2014), and chairing the ECC (2014-2020). Throughout my envolvement with the BES I have had positive experiences and enjoyed contributing to a society that can get things done. Since I have been involved with ECC we have launced under-graduate and A-level summer schools, introduced a mentoring scheme for acadmices, and helped to encourage academics to engage the public with science. If you are interested in helping us to develop the activity of the society please consider joining us!
