Environments Through Time

November 18, 2022
WDG

The University of Amsterdam “Environments Through Time” course is currently underway. This cross-disciplinary course is part of the MSc Biological Sciences program and also attracts many students from the MSc Earth Sciences. During the course students gain an understanding of the importance of having a long-term (centennial to millennial) context to understanding environmental problems, and how datasets can be generated that are relevant to these timescales. To gain an understanding of uncertainty in reconstructing past environmental change students conduct a re-analysis of previously published datasets (such as those archived in Neotoma) and assess if the findings of those papers was robust. To do this students develop skills in data mining, Bayesian probability modelling, multi-variate statistical analysis, and change-point analysis. At the end of the course students have gained experience in the critical evaluation of the scientific literature, transferable numerical skills, and a greater appreciation of Earth history and past environmental change.

If you would like to learn more about past environmental change and its relevance to ongoing societal, climatic and ecological change sign up for the MSc Biological Sciences or MSc Earth Sciences and take this course. If this course sparks further your interest in exploring past environmental change then further opportunities exist to take on masters projects in this field with our team.

Detecting past peoples in the tropics

January 22, 2020

Detecting the presence, and impact, of peoples past impact in ecosystems and landscapes in the tropics is a challenging because the traces that they leave behind are few and disentangling them from ‘natural’ (non-human related) variability is a challenge. As an Associate Editor for Vegetation History & Archaeobotany (VHAA) I enjoy handling manuscripts that think about these issues and explore the role of humans in tropical landscapes. Two recent papers published in VHAA touched on this subject (one of which I “communicated” as an editor).

Bodin et al. (2020) studied charcoal recovered from soil at sites with a gradient of archaeological evidence for past human activity in French Guiana.
Goethals & Verschuren (2019) explored the relationship between the amount of dung fungi found in lake sediments and the herbivore populations living around the lakes.

Climate change and precipitation in past present and future: Mini symposium

June 13, 2016

Research Group of Palaeoecology & Landscape Ecology
Institute for Biodiversity & Ecosystem Dynamics
University of Amsterdam

Date: 17/06/2016
Time: 13:30-16:00
Location: Amsterdam Science Park 904
For registration & full details please contact: Dr. John van Boxel

When addressing climate change the focus often is on temperature. However precipitation is a climate variable that is at least as important, but much more difficult to assess. This mini symposium will address several aspects of the changes in the precipitation climate. William Gosling shows how climates in the far past can be reconstructed using proxies. One of these proxies, biomarkers, will be discussed by Susanna Mölkänen, who uses them to reconstruct altitudinal gradients. John van Boxel discusses 20th century climate change in the Netherlands focussing on changes in precipitation extremes. The models that are used to study climate change are the topic of the presentation by Geert Lenderink from KNMI. Some of these models were also used by Emma Daniels (WUR) to study the effect of urbanisation on precipitation in the Netherlands. For anyone involved in climate change and precipitation this should be an interesting afternoon.

PDRA: Past environmental and climate change in West Africa

March 29, 2013
WDG

Full time Post-Doctoral Research Associate, Temporary contract for 36 months, £27,854 – £36,298
Department of Environment, Earth & Ecosystems, Faculty of Science, The Open University

Closing date : 25/04/2013

The PDRA project will descover more about past vegetation and climate change in Lake Bosumtwi (Ghana)

We are seeking a PDRA to study past climate and vegetation change in tropical West Africa as part of the NERC-funded “500,000 years of solar irradiance, climate and vegetation changes” project. You will join a multidisciplinary collaborative research team and will work with an international network of project partners. The project will utilise cutting-edge organic geochemical techniques to generate the longest continuous record of fossil pollen chemistry change. The study will build upon previous research into the sediments recovered from Lake Bosumtwi (Ghana). The data generated will shed new light on the role of climate in driving vegetation change in the tropics.

You will already hold a PhD, or be near to completing your PhD, in a relevant scientific discipline with a background in the Earth or Environmental sciences. You must have substantial experience of organic geochemistry or tropical palynology, with well-developed self-management skills and the ability to prioritise effectively.

The PDRA will work with an associated PhD student looking at modern pollen-vegetation relationships in the same region.
