Analysing Bat Diversity on Peatland PV Sites Using Audio Data
Time: from spring 2026
Contact: Hanna Martens (hanna.martensuni-greifswaldde)
Master thesis
Introduction: To reduce greenhouse gas emissions, rewetting of peatland soils is urgently needed, as is a transition to green energy sources. While the expansion of solar parks is happening rapidly, rewetting peatlands is slow to progress. One option for peatland rewetting that is currently being explored is the construction of solar parks on rewetted peatlands. This has the potential to provide green energy while also reducing the greenhouse gases emitted from the soil. However, this is a very new concept, and there is little understanding of how biodiversity will respond to such a land use. The project MoorPower is the first of its kind, setting up an experimental site to assess the impacts of rewetted peatland PV from many different angles, including hydrology, peat formation potential, microbiology, and other topics.
This thesis project would focus on bat species. As part of this project, you would have the opportunity to learn to identify bat species that live in wetlands and agricultural landscapes. Additionally, you would learn about the rapidly evolving methods for species determination with machine learning. The thesis work will include some fieldwork, but is focused on processing and analysing large datasets.
Methods:
In 2026, AudioMoth audio recorders will be set up in the solar park and at reference sites. Methods for analysing this data will include use of machine learning and human verification through visualizing sound waves. This data can then be analysed to determine the species groups present at the peatland PV site and in the surrounding intensively used grassland on drained peatland.

Croaks to Chirps: Mapping the Listening Limits of Bioacoustic Monitoring in Open Landscape
Time:
Field recordings: spring–summer 2026
Data analysis: spring–autumn 2026
Location:
Experimental peatland sites within the PaludiZentrale project, Mecklenburg-Western Pomerania
Contact:
Alexander Drexler, Dr. Susanne Arbeiter
Background:
Passive acoustic monitoring is an increasingly important tool in biodiversity research, offering a non-invasive way to detect species and study their activity patterns. Within the PaludiZentrale project, AudioMoth recorders are used on experimental peatland restoration sites to monitor biodiversity. However, the effective detection range and directional sensitivity of these recorders under typical mire field conditions have not yet been systematically assessed.
This thesis focuses on understanding what we can hear and from where: How far and from which directions can different species groups (e.g., birds, amphibians, insects) be detected in an open landscape? The work aims to evaluate the performance of AudioMoth devices for different taxa and acoustic conditions and to contribute to improving bioacoustic monitoring setups in peatland ecosystems.
Methods:
You will conduct field experiments with AudioMoth recorders, using standardized sound sources and real species calls to assess the detection range and microphone directionality under natural conditions. In addition, recordings from ongoing monitoring sites will be analyzed to identify species and evaluate detection probabilities. You will gain insights into semi-automatic bioacoustic data processing, acoustic ecology, and field-based biodiversity monitoring.
Depending on your study level and interest, the focus can be more experimental (field- and method-oriented) or analytical (data and signal analysis). Both Bachelor’s and Master’s theses are possible, and the scope will be adapted accordingly.
You will contribute to the PaludiZentrale research project, which investigates biodiversity and ecosystem processes in rewetted peatlands. Are you interested in combining field ecology, technology, and biodiversity monitoring? Then this project might be ideal for you.
Development of a cattail cultivation and accompanying vegetation on an 8-hectare experimental field, five years after establishment (MA)
Time: field work in July 2026
Location: Experimental field near Neukalen
Contact: Josephine Neubert (josephine.neubert@uni-greifswald.de
Introduction: To reduce greenhouse gas emissions, soil degradation and soil subsidence of drained peatlands, rewetting of these sites is urgently needed. An important question for farmers and society is how to keep these areas productive - especially for Mecklenburg-Western Pomerania, rich in fen sites.
Paludiculture, as the productive use of wet and rewetted peatlands for example with the cultivation of suitable plants, is a promising solution.
Near Neukalen, a cattail (Typha spp.) field of approx. 8 ha was established in 2019, to investigate the cultivation of large-scale paludiculture on a rewetted peatland. The initial focus was to answer questions about e.g. the feasibility, economics, and biomass quality of cattail in the first years after establishment. Since 2022, a new project Paludi-PROGRESS (“Paludiculture in practice: Optimisation of cattail and reed cultures”) is testing and further developing the cultivation of cattail as a new
permanent crop.
Methods: In the first vegetation period, 80 plots were already established and vegetation surveys took place over the following years (2020-2026). In the vegetation period of 2026, we want to continue to monitor the development of the target species and its accompanying vegetation in the sixth year by assessing e.g. plant height, species composition and plant cover. Furthermore, we want to identify the influence of environmental factors, such as the water table level, and mowing intensity on cattail plants. The data for the thesis will be collected during several days of fieldwork on the experimental field near Neukalen (first two weeks in July). Species knowledge of wetland plants is beneficial, but can also be acquired during the data collection.
Spring phenology - how beneficial is it to leaf our early? (Kopie 1)
Time: Data collection from November to December 2025
Location: Campus Soldmanstraße 15
Contact: Ilka Beil
We have grown beech seedlings of different phenological behaviour closed together for some years. We applied one late frost event, and summer drought of different severity. Which seedlings grew better, the early flushing ones, who made better use of the moist conditions in spring, or the late flushing seedlings that avoided the late frost? - You can figure out!
Comparing phenology of beech saplings form different regions of Europe
Time:
Growth: winter 2025/2026 and winter 2025/26
Spring phenology: end March - begin May 2026
Autumn phenology: September - ca. November
Location: Forest near Hanshagen
Contact: Ilka Beil
Background:
Plants phenology is typically optimized in a way that the growing season is as long as possible while the risk of freezing is as low as possible. In a widespread species like Fagus sylvatica (European beech) one would expect that different ecotypes, developed in different regions of Europe, show some variation regarding spring and maybe even autumn phenology. If climate is now getting warmer and winters become shorter, plants with earlier leaf out strategies in spring and later autumn coloration might be at an advantage, because they have more time to grow over the year. An early onset of growth is even more important when the likelihood of summer drought is rising.
Methods:
We planted beech seedlings originating from different regions in Europe into the forest near Greifswald following a randomized block design. After establishment in 2020 they are now ready for comparing the spring and autumn phenology as well as tree growth of the different provenances (ecotypes). In winter, we measure height and stem diameter. End of March until begin of May, spring leaf out will be observed 3 times a week and in autumn (September until November) leaf senescence will be assessed every week. You will be part of a research project, that investigates phenology and growth of beech provenances over many years. Are you interested in a bachelor or master thesis that might have interesting implications for forest management? Then this project might be interesting for you.
Root phenology of fen plants in mesocosms with different nutrient loads and water regimes
Root phenology of fen plants in mesocosms with different nutrient loads and water regimes
Timing: from spring 2026 onwards
Contact: Juergen Kreyling
Plant roots play a key role in ecosystems and are particularly important in fens, where the roots and rhizomes form peat and thus store large amounts of carbon. However, little is known about the root dynamics under different nutrient loads and water regimes.
Weekly minirhizotron scans will be used in a mesocosm facility and automatically evaluated by an existing AI-algorithm.
Plant roots play a key role in ecosystems and are particularly important in fens, where the roots and rhizomes form peat and thus store large amounts of carbon. However, little is known about the root dynamics of reed and sedges, for example, how the roots and rhizomes respond to different water levels or periods of drought. This is being investigated, among other things, as part of the Paldui-PROGRESS project.
As part of the project, various theses are possible at the University of Greifswald's mesocosm facility:
Use of mini-rhizotrons (root cameras) in a mesocosm facility to evaluate root growth and root architecture of reed and sedges under different groundwater conditions.
Evaluation of the biogeochemistry and gas fluxes that arise at different groundwater levels in the mesocosm facility.
Root dynamics in drained and rewetted peatlands in the face of climate change (MA or 2 BA)
Timing: first and/or second half of 2026
Contact: Bo Peters & Jürgen Kreyling
Location: Greifswald
Peatlands are globally important carbon sinks, but drainage of peatlands leads to a release of the stored carbon and to large emission of greenhouse gases. To reduce greenhouse gas emissions, efforts are made in rewetting these systems in the hope of restoring their potential as carbon stores.
Here, the root growth dynamics in three different types of drained and rewetted peatlands (alder carr, percolation mire and coastal mire) are assessed by the minirhozotron technique. The same observations occurred already in the extremely dry and warm years 2018 and 2019 and 2020, when water tables even in the rewetted fens dropped below -60 cm. According to the IPCC report (2013), these extreme weather conditions are projected to increase with climate change. Long-term observations of root dynamics in drained and rewetted peatlands will increase our knowledge on how these ecosystems might react to changes in climate and if they are able to maintain their important function as carbon sinks in the future. This project is within the framework of WETSCAPES2.0.
Methods: Using minirhizotrons (root cameras), root growth in space and time is analysed at drained and rewetted peatlands in MV, which will be visited monthly during the growing season. A driving license is needed and an own car is a merit (travel costs will be covered).
