Even though there is quite a lot of snow and minuses outside, the fieldwork season is now open! Last week we had couple of visitors from the Swiss Federal Institute for Forest, Snow and Landscape Research in Zürich – researcher Marco Moretti and his PhD student Joan Casanelles -, who were here in the framework of our joint urban ecology ERA-NET project BioVeins (2017-19).
The plan is to study green and blue urban infrastructure (basically city parks, and parks with water bodies) in Antwerp, Zürich, Paris, Poznan, Lisbon, Almada and Tartu from the point of view of park size and spatial isolation, and the ecosystem services they provide.
Our Swiss colleagues are studying the zoological aspects of city parks, monitoring insects and bats. And for that they installed, with the help of two local PhD students, Tiit Hallikma and Marta Alos Orti, insect trapnests in 12 selected sites in Tartu. These look like slightly oversized birdhouses, but actually contain typical infrastructure of a bug hotel. Plus, there is an additional space for the instrument that “hears” bat signals.
Here are couple of pictures from the two-day fieldwork. (For more pics, click here.)
