Urban vs. rural pollen chemistry project design

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.

Plant Ecology & Diversity: Global Change & Vegetation Dynamics

February 10, 2020
WDG

As a palaeoecologist and biogeographer I am delighted to have become a Subject Editor for Plant Ecology & Diversity (PE&D). In my new role for the journal I hope to handle a broad range of articles within my area “Global Change & Vegetation Dynamics: Past, Present & Future”. As Subject Editor, as well as organizing general submissions, I would also like to promote a range of articles focused on scientific themes that build upon key publications.

The first of these themes will be “long-term ecology” and will build upon the recent ‘monster’ Grubb Review written by John Birks (Birks, 2019). The Birks manuscript covers a vast range of topics centred on the contribution of Quaternary botany to understanding modern ecology and biogeography. Topics covered within the Birks manuscript include:

  • Vegetation range shifts
  • Extinction events
  • Human impacts on ecosystems
  • Biodiversity trends
  • Conservation

I plan to pull together the “long-term ecology” set of manuscripts for PE&D during 2020, and contributions are welcome on any of the issues and research areas highlighted in the Birks manuscript.

African Pollen Database – Data stewards

January 29, 2020

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:

African Pollen Database data steward training event

APD “Awesome” in Paris October 2019 – Vincent Montade, William Gosling, Chris Kiathipes, and Manu Chevalier (l-r)

The African Pollen Database (APD; Vincens et al., 2007) has recently received a new life thanks to the work of Anne-Marie Lezine, Eric Grimm, Sarah Ivory and Jack Williams who have obtained funding to develop the digital infrastructure and link to the Neotoma Palaeoecology Database (Williams et al., 2018) and the Institut Pierre-Simon Laplace (IPSL) Paleoclimate database. The kick off meeting was held at the IRD centre in Bondy (October 2019), and the next step (training the data stewards) will be held in my department within the Institute for Biodiversity & Ecosystems Dynamics (University of Amsterdam) next week (January 2020).

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.

Detecting past peoples in the tropics

January 22, 2020

Vegetation History & ArchaeobotanyDetecting 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.
