Veerle and I trying to protect ourselves from the mosquitos.

Hi all!

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!

Cheers,

Britte

The impact of people on islands

January 19, 2018
WDG

Since being appointed as an Associate Editor of Vegetation History & Archaeobotany last year I have the pleasure of working on a number of exciting and interesting manuscripts from the tropics. I am particularly delighted that the first of these (Astudillo, 2018) has now been published. I particularly liked this manuscript because of: (i) the close relationship that was shown between the historical and fossil records, and (ii) the clear signal shown from working on a island system. This linkage is something I have been thinking about in my own research on Mauritius recently (Gosling et al., 2017) and is, I believe, particularly valuable to do because it demonstrates the validity of techniques to track human activity when applied in contexts without historical documentation. The impact of people on the Galapagos is shown by Astudillo (2018) from investigation of multiple proxies (charcoal, phytoliths and macrofossils) to build up a comprehensive picture of human impacts on one of the most famous places for biodiversity on Earth. Hopefully this study is just the start of investigations into past human impacts on the Galapagos islands, and I hope that you enjoy reading the manuscript!

On Jan 1, 2018 I (Crystal McMichael) get to ring in the New Year in the best way possible by heading off to the tropics to do fieldwork! And this time I get to take two students with me. Britte Heijink and Veerle Vink are both in the Biological Sciences MSc program (Ecology and Evolution track), and they are going to work on research projects that are associated with a recent grant that I was awarded through the Smithsonian Tropical Research Institute CTFS-ForestGEO Research Grants Program.

Job: Post-doctoral researcher in Palaeoecology

November 30, 2017
cmcmicha

Job: Post-doctoral researcher in Neotropical Palaeoecology
Location: Institute for Biodiversity & Ecosystem Dynamics, University of Amsterdam
Duration: 3 years
Deadline for applications: 15 January 2018

We are seeking to recruit a Neotropical palaeoecologist to join the recently funded “The past peoples of Amazonia: Assessing ecological legacies” project (PI Dr. Crystal McMichael, funding NWO, based within the Department of Ecosystem & Landscape Dynamics). The project aims to reconstruct cultural histories from lake sediments in northwestern Amazonia, and link past human activities with modern ecological observations. The project involves analyzing microfossils (including pollen, phytoliths, and charcoal), and the development of a transfer function that estimates past human impacts in tropical forest systems.

We are particularly looking for a candidate with  expertise and experience, in:

  • Fieldwork in remote areas.
  • Neotropical pollen.
  • Quantitative analysis, including familiarity with R and Geographical Information Systems.
  • Academic publication.

Evidence of early cultivation around the globe

October 24, 2017
WDG

Two recent articles published in the journal Vegetation History & Archaeobotany, which caught my attention as an Associate Editor, explore early cultivation in Argentina and Czech Republic:

  • Lopez (2017) examine macro-botanical remains from 16 archaeological sites in Argentina and concludes that the transition from foraging to cultivation commenced around 1000 years ago.
  • Dreslerová et al. (2017) looked an charred macrofossil remains from 84 archaeological sites in the Czech Republic to think about how early farmers selected the crops they grew.

vhaHaving recently become an Associate Editor for Vegetation History & Archaeobotany I have decided that I will try and highlight a couple  papers from the journal each months which have caught my attention. My first selections are:

  • A study which demonstrated the close relationship between the fossil fungal spore record and historical accounts (Orbay-Cerrato et al., 2017).
  • An investigation of a human modification of ecosystems on the sub-tropical Pacific island of New Caledonia using fossil wood charcoal remains (Dotte-Sarout, 2017)

Scientific methods in archaeology

November 10, 2016
WDG

Preparing my lecture for the new Scientific Methods in Archaeology course for VU Amsterdam and University of Amsterdam students studying a minor in Geoarchaeology. The focus will be on detecting human activity in the past, to illustrate this I will include Easter Island/Rapa Nui as a case study. We will focus on how palaeoecological evidence can be used to gain insights into past human activity. Whilst putting this together I discovered these nice documentaries looking at humans and their environmental impacts on Easter Island/Rapa Nui which I wanted to share, they show how much effort people would have had to put into altering their landscape:
