Scientific Archaeology 2021

November 13, 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…

Mapping Ancient Africa: Report of kick off meeting

The kick off meeting of the INQUA funded Mapping Ancient Africa project took place on the 14 and 15 October 2021. This hybrid meeting linked up face-to-face meetings in Kenya, South Africa, Germany and the USA online. In total around 35 people participated in the meeting over the two days. It was great to start to get researchers back into rooms together, and to take advantage of the online link ups to connect people within regions who could not travel, and people in different continents. The purpose of the meeting was to introduce the researchers to each other and to start to think about how we can work together to deliver the project goals of collating and synthesising data related to past climate, vegetation and hominin activity from across the continent.

Scientific Archaeology 2020

November 20, 2020
WDG

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:

Keep on pollen sniffing

May 5, 2020
WDG

By Cas Verbeek (University of Amsterdam)

Luckily, in spite of these trying times, we are allowed to continue our research in Amsterdam and on the Veluwe to determine the effects of air pollution on airborne pollen grains. Unfortunately for us (but generally perhaps one of the few silver linings of this situation), the COVID-19 lockdown has largely eliminated our main variable of interest; air pollution.

With traffic in the city at a minimum, any chemical differences might not be as pronounced between the city and rural areas. However, this may actually provide us with a unique opportunity to get a baseline of the pollen chemistry in Amsterdam with relatively little pollution. This baseline may also be of interest to projects working on urban air quality and greenifying urban spaces, such as the projects in the Amsterdam Knowledge Mile Park, which is included amongst our sampling locations.

Pollen in the Netherlands

April 21, 2020
WDG

By Letty de Weger (Leiden University Medical Centrum)

In the coming weeks lots of pollen can be collected. Due to the nice, sunny weather birch trees are in full flower and release their pollen into the air.  This is of course not so good news for the individuals sensitized to the pollen of birch because they can suffer from hay fever symptoms.

Next to birch also the ash trees are flowering. The black buds of the ash branches have bursted, releasing the purple anthers (first figure). Among those anthers you can see some that release their yellow pollen  (second figure).

Neotoma PackratAn African Pollen Database data steward training event was held at the Institute for Biodiversity & Ecosystem Dyanmics (University of Amsterdam, 27-29 January 2020) where training in the use of the Neotoma database was provided by Eric Grimm. The participants are now enabled curate and archive data within Neotoma. If you have a palaeoecological data set that you would like to contribute to Neotoma, or if you would like training as well, these people can now help you. Contact details below:
