Jan Wieringa planten aan het inleegen in Swaziland

Ik heb een brede interesse in planten en dieren, met een geografische focus op Europa en Afrika. Mijn oudste interesse gaat uit naar insecten, met name sprinkhanen en krekels, maar ik heb ook interesse in kevers. Binnen het plantenrijk werk ik het meest aan soorten uit de peulvruchten familie en Begonia. Een recent project betreft Cassytha, een parasitaire klimmer uit de laurierfamilie. Ik heb vooral veel kennis over de flora en fauna van Gabon, waar ik meer dan twee jaar veldwerk heb gedaan.

Naast dit taxonomische en floristische/faunistische werk, verwerk ik gegevens van collectie exemplaren om zo iets te kunnen zeggen over de verspreiding van soorten om daarmee biodiversiteitsstudies te maken. Dit doe ik vooral voor de Afrikaanse botanische diversiteit. Mijn onderzoek binnen Nederland richt zich juist op insecten.

Research
interests

I am a biologist, with a focus on biodiversity. On one side I want to make biodiversity accessible by producing keys, describing new species and building databases on biodiversity data, on the other hand I am exploring it by assisting in biodiversity assessment studies.

Current taxonomic research is on:

- Begonia (Begoniaceae)
- Cassytha (Lauraceae)
- Lindackerieae (Achariaceae)
- Detarioideae (Leguminosae)
- African Phaneropterinae (Orthoptera, Tettigoniidae)

Current biodiversity studies focus on:

- Plant diversity of the world, particularly tropical Africa
- Insect fauna of The Netherlands
- Entomofauna in cities

Teaching

My teaching is either flora and fauna courses: how to identify plants and insects, and show where and how they live in the field, or it is lecturing about biodiversity assessment, and the biases in biodiversity data.

I am assisting the course "Biodiversiteit en Ecologie" at the University of Amsterdam. In this course of 4 weeks, the first week is spent in the lab teaching insect orders and plant families. The second week we visit several vegetation types like dunes & salt marshes, heathland and marshes were we demonstrate the biodiversity of these areas, and show the effect of clines in water availability, nutrients, salt and light to the vegetation, and the fauna that is linked to that. The third week the students have to perform a field study in southern Limburg, where they will sample the entomofauna and record the vegetation in 9 plots over a cline from the hill top to the valley bottom. The fourth week the insects from Limburg will be identified, the data processed, and conclusions drawn regarding the field work.
