Keep on pollen sniffing

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

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:

A Study in Green

July 5, 2019
WDG

By Rachel Sales (Florida Institute of Technology, USA)

My bike is angry at me.

I’m rattling down an unpaved road in the Ecuadorian Amazon. The brakes screech at every turn, and the chain is close to falling off. Unsurprisingly, the rain is pouring, turning the road into a maze of puddles and mud. The road follows the Anzu River, and I can hear its roar off to my right.

I’m forcing a perfectly innocent bike to brave the Amazon because this road leads to the Herbario Amazónico of the Universidad Estatal Amazónica (ECUAMZ). ECUAMZ (an acronym for “Ecuador Amazon”) is the only herbarium in the Amazon, and contains a repository of plant specimens for preservation and help with field identifications. It was established by Dr. David Neill, a specialist in the Fabaceae (legume) family and world-renowned expert in tropical botany, and Dr. Mercedes Asanza, the coordinator of the herbarium. They have agreed to mentor me over the summer and teach me about tropical plants. The Herbario Amazónico, which contains over 17,000 vascular plant species, is the perfect place to learn.
