Topics for bachelor and master theses
Below is a list of topics for B.Sc. or M.Sc. theses. If you are interested in doing your research in our group the procedure is as follows:
- go through the list and topics and find what you are interested in
- contact the direct supervisor by email and ask for more information
- make an appointment with your direct supervisor to discuss the topic, timeframe etc. in more detail
- if you have found a topic that you would like to choose there will be a meeting between your direct supervisor, yourself and W. Weisser, to discuss the design of your study, starting dates, financial aspects and other formalities.
- you develop a thesis plan that will be part of the formal agreement between yourself, your direct supervisor, and W. Weisser for the thesis
- If you are interested in a topic that is not listed below or if you have any other question please feel free to contact W. Weisser or any other person in the group.
Urban areas are expanding rapidly, yet we still have limited knowledge about how city structures influence insect populations. Insects play vital roles in ecosystems, contributing to processes such as pollination, pest control, and soil health. Cities represent unique habitats characterized by fragmented green spaces, varying temperatures, and artificial surfaces, which can either benefit or harm different species.
By investigating how urban structures affect insect diversity and abundance, we can develop strategies to support biodiversity in urban environments. This research is not only scientifically significant but also has practical applications in conservation, urban planning, and sustainable city development. If you are interested in this, this thesis topic presents an opportunity to make a meaningful impact!
We are offering one to two master‘s theses for motivated students to explore how city structures affect arthropod populations in Munich. We will sample ants using pitfall and bait traps and use a variety of sampling methods for other arthropod groups (Insect cameras, trap nests, light traps).
Sampling will occur in various locations throughout Munich, including the city center and surrounding districts.
The master theses include the following work steps:
Literature review on your thesis topic
Fieldwork in Munich in summer
Statistical data analysis in R
Digitization of collected data
Writing
Requirements
Most important is that you are motivated and interested in the topic. You will be supervised by Zoé Hentschel, a PhD student at TUM and Prof. Wolfgang Weisser. We provide a vivid working environment with many Master’s and PhD students with whom you can interact and learn from/together with. We expect that you have some experience with data analysis in R. Prior experience with arthropod sampling is beneficial. The project results might contribute to a publication based on the outcome and the derived data. The theses start in May, at the latest in June 2025. The theses can be supervised in German or English.

Effects of habitat elements and substrate depth on plant and insect diversity on extensive green roofs
Green roofs offer the opportunity to promote biodiversity, in addition to other functions such as improving the appearance of a building or reducing the heat island effect and surface water run-off. Green roofs can, at least in theory, serve as a refuge for insects and a potential food source for birds and bats. However, green roofs are exposed to extreme climatic conditions, the effects of which are exacerbated by their shallow substrate depth. How exactly the ecological function of green roofs can be enhanced is still relatively unknown, especially for animals.
As part of the ‘Animal-Aided Design’ project, the roof of a building in Brantstraße in Munich-Laim was greened and developed as a test area. An experimental approach will be used to test whether small changes in soil depth (mounds) or the addition of piles of stones, dead wood or refugia can increase the diversity of animals or plants.
The Master's theses focus on either plants or animals. The following work steps are planned:
- Sampling of plants or animals, in particular above-ground insects and soil animals
- Identification of the plants or animals (in some cases sorting by order)
- Statistical analysis of the data to test which of the approaches have positive effects on plants or animals.
If the work is successful, the results can be published together with other data. The Master's thesis will be supervised in German and English.
