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.

Does environmental pollution enhance the allergenic nature of pollen? This is the question that drives my NWO Idea Generator grant that has just started. This project links up the pollen chemistry expertise in my group within the Department of Ecosystem & Landscape Dynamics (University of Amsterdam) and the work of Letty de Weger into human health and pollen (Leiden University Medical Centrum). Over the 2020 flowering season we will be monitoring pollen in Amsterdam (urban) and in the Hoge Veluwe (rural) in the space in which people have allergic reactions to see if there is any chemical difference between the pollen in urban and rural settings.
We are delighted that Cas Verbeek has joined the team as a Research Assistant; taking time out from his MSc Biological Sciences degree (University of Amsterdam). Cas is already busy in the field and lab fine tuning our collection and analysis protocols.
Pollen data recorded in Neotoma for Africa on 24 January 2020. Hopefully after the data steward training event we will have a few more dots on the map, and the potential for many more.
We are delighted to be able to host sixteen researchers of many nationalities conducting research in many different countries. The aim of the training event is to provide researchers with the skills to manage Neotoma and strengthen the African pollen research community. I am excited to be involved, I am confidence that much new research will be brought together, and I hope that we can get good plans in place for further steps and growth of this network.

IBED is looking for an Earth scientist/ecologist with expertise and interest in soil carbon cycling, in relation to the role of soil microbial communities therein to support ongoing work within the Department of Ecosystem & Landscape Dynamics (ELD). We are particularly looking for a researcher with an international track record with expertise in one, or more, of the following areas:
Interactions between organic carbon and the mineral soil.
Microbe-organic C interactions.
Molecular and computational approaches for analysing soil microbial communities and their functionality.
Scaling of soil carbon cycling processes from microbe to globe.
Linking global carbon cycle models and laboratory experiments.
This is one of two positions currently open in Earth Systems Science within ELD. The other position is related to Environmental Chemistry and we will be looking at complimentary between the two appointments.
