WDG

As part of this years BSc Palaeoecology course at the University of Amsterdam we visited the Department of Archaeology. Organised by Anja Fischer we visited the human bone collection, the animal bone collection and the archaeobotany section. Amazing collections and lots of opportunities for cross faculty projects and teaching.

In addition to explaining the physical reference collections Anja also explained how she has been developing data mining techniques to allow information to be synthesised from the thousands of archaeological reports across the Netherlands.

She used this approach to make new discoveries about the role of urban farming and ruralisation in Dutch history. Her findings formed a report for the Dutch national heritage organisation (Rijksdienst voor het Cultureel Erfgoed) which can be downloaded for free (in English).

The University of Amsterdam (UvA) palaeoecology course is underway. The course is part of the BSc Biology program and the “Earth & Ecology” minor of the BSc Future Planet Studies.

Week 1 (last week) we got everyone up to speed with the fundamentals of palaeoecology (including: key principles, depositional environments, dating methods) and laboratory skills (pollen, phytolith and macrofossil identification). This week (week 2) we are out and about (coring sediments, surveying vegetation and visiting the archaeology department). By the end of the week the students will (should!?) have generated sufficient data in the laboratory and field to be able to identify the location from which their mini-project “mystery slides” were taken. Next week (week 3) will be number crunching to generate the statistical support for their ideas and inferences.

These samples were recovered in collaboration with the BosGroep Zuid Nederland as part of an ongoing project to gain new insights into the nature of the past landscape in the Netherlands and aid conservation efforts.

Scientific Archaeology 2021

The Science in Archaeology 2 course, run as part of the minor in “Archaeology Today” by the Amsterdam Centre for Ancient Studies and Archaeology (ACASA), is currently underway. This year I have again contributed to this course with a weeks worth of activity related to detecting past human impacts. During this week we have focused on what sorts of evidence contained within the sedimentary record can be used to track human actions. We focused in particular on the manipulation of fire regimes and the the abundance of animals in landscapes (i.e. extinctions vs. introductions of domestic species). To illustrate how past human activities can be detected in landscapes I tapped into some recent publications I have been involved with (eastern Andean flank, Samoa and Mauritius) and the students selected papers in line with their own focus to discuss. Here is what they came up with…

This year my contribution to the Science in Archaeology course (VU Amsterdam) was done online due to the COVID-19 restrictions. The course comprised live online lectures, pre-recorded video clips and case study discussions. The focus was how to detect past human impacts on the landscape and we explored many proxies including: charcoal, diatoms, egg shells, non-pollen palynomorphs, phytoliths, and pollen. In the final session of the humans impacts section of the course each student presented a case study paper that they had chosen. Here is what they chose:

Scientific Methods in Archaeology

November 21, 2018
WDG

VU AmsterdamOver the last two weeks I have been giving my lectures at the VU Amsterdam “Scientific Methods in Archaeology” bachelor program. In my lectures we think about how to detect past environmental change with particular reference to tracking past human activities. As part of our exploration of past human-environment-climate interactions each student is asked to choose a scientific article, summerise it, and we then discuss it in class. The three papers sected this year covered the Neolithic of the Netherlands (Weijdema et al., 2011), a overview of Mediterranean and north African cultural adaptations to drough events during the Holocene (Mercuri et al., 2011), and an exploration of the role of humans in mega-faunal extinctions in South America (Villavicencio et al., 2015). All papers provided interesting points of discussion and an opportunity to think about different aspects of how we investigate past environmental and societal change.

Environments Through Time paper presentations

November 6, 2018
WDG

The 2018 edition of the University of Amsterdam masters course “Environments Through Time” is now up and running. The course sits at the interface between ecology, physical geography and archaeology and seeks to provide students with a better understanding of how long-term (>100’s years) datasets can provide insights in to past environmental change.

In the first week of the course the students had to present their ‘favourite’ paper in just three (3) minutes! Quite a challenge and lots of fun. This years selection of papers themed around:

  • mega-fauna extinctions (Bakker et al., 2016; Gill et al., 2009; van der Kaars et al., 2017),
  • impacts of human land use practices (Bitusik et al., 2018; Carson et al., 2014; Chepstow-Lusty et al., 2009; Gauthier et al., 2010; Tisdall et al., 2018), and
  • climatic drivers of vegetation change (Haug et al., 2001; Tierney et al., 2017; Tudhope et al., 2001).

For full list of papers presented see below.

In the second and third weeks (now ongoing) students get to deconstruct published chronologies and conduct time series analsis of multi-proxy datasets. Data for these excercises is frequently is extracted from databases such as Neotoma, Pangea, NOAA – paleoclimatology datasets database and the Global Charcoal Database – which shows the importance of these open access databases for developing effective research led eductation, as well as pushing forward to frontiers of research.

Environments Through Time is taught in English, delivered by myself (William Gosling), Crystal McMichael and Milan Tunissen van Manen and currently has 31 registered students from MSc Biological Sciences and MSc Earth Sciences degrees.

Britte reconfiguring the chronology for Lake Pata

Britte reconfiguring the chronology for Lake Pata

The second and third weeks of the Environments Through Time course at the University of Amsterdam has focused on obtaining practical experience of developing chronologies, analyzing multi-variate data-sets, and conducting time series analysis. The focus of the course has been on Quaternary environmental change, however, the skills learnt can be applied to almost any time-scale so long as you have time control points you want to tie together, and multiple things you can track changing through that time.

Over the two week period the students worked on a previously published paper that they had selected that contains: (i) chronological information (at least 3 control points), and (ii) multiple variables that change through the time series (at least 9 variables). In week two they deconstructed the chronologies and generated their own revised versions. For example students have (re-)calibrated radiocarbon dates, made different decisions on dates to include/exclude, and used different approaches to constructing the age vs. depth model, e.g. contrasting linear point-to-point vs. Bayesian methodologies. In week three they have taken the data-set(s) associated with their paper and re-evaluated it in light of the revised chronologies using cluster analysis, ordination techniques, and wavelets.

Through this exercise students have gained experience of how to critically assess scientific literature and gained an appreciation of where re-analysis of data-sets can (and cannot) make a difference. Personally I have be delighted with the high level of engagement and enthusiasm for the material and have been excited to have a chance to delve into literature that I would not otherwise be aware of.

Me teaching human impacts on environmental change…

The first, ever, week of the Environments Through Time course at the University of Amsterdam has just finished. The course sits within the MSc Biological Sciences (Ecology & Evolution) and MSc Earth Sciences (Geo-ecosystem Dynamics) but is also avaliable to other masters students. In the first week we have thought about four main topics:

  1. Scales of change (ecological, geological, and human).
  2. Humans as drivers of environmental change.
  3. Extra-terrestrial forcing of environmental change.
  4. Earth system feedbacks.

The week was completed with each student giving a three (3) minute presentation of their favourite paper. The papers presented ranged from the extinction of giant sharks, through forest-savannah transitions, to how climate change thwarted Ghengis Kahn. Next week we continue by disecting how chronologies are constructed.

Success for BSc project students

BSc students on the Palaeoecology course prior to undertaking a research project with us.

Many BSc students undertook our “Palaeoecology” course prior to choosing to do a research project with us.

This year 15 (fifteen!) bachelors students completed their research projects in palaeoecology based within the Department of Ecosystem & Landscape Dynamics at the University of Amsterdam. The students had a variety of backgrounds with the majority coming from the BSc Biology and the BSc Future Planet Studies programs.

Each project was set up to test a particular ecological or biogeographic hypothesis. Investigations included the exploration of the role of humans in modifying ecosystems in Amazon, the nature of the pre-farming landscape in the the Netherlands, and how to chemically identify fossil charcoal. In undertaking their projects individual students had the opportunity to variously develop skills in microscopy, spatial modelling, or analytical chemistry. The high quality of the data produced means that hopefully many of these data sets can be used in future scientific publications. Well done to all!

If you are interested in conducting a similar project (at any academic level) with us please do not hesitate to get in contact. For further details of ongoing research within the Department of Ecosystems & Landscape Dynamics visit our web pages by clicking here.
