The impact of people on islands

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!

Off to the tropics!!

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

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

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.
