Urbanization is one of the greatest challenges for biodiversity. Yet, there is still not enough knowledge about how species cope with the conditions in urban areas. In her doctoral research, Sinah Drenske investigates the impact of urbanization on squirrels (Sciurus vulgaris) in Berlin. The study shall create a scientific basis for the ecology of squirrels and to understand whether and how they can adapt to urban environments. The aim is to decipher which biotic and abiotic factors determine the distribution and prevalence of squirrels.

Drenske is measuring how population densities differ at different locations along a rural-urban gradient over a period of three years and which individual characteristics (such as body size and weight) and health conditions captured squirrels exhibit. In addition, she investigates the factors that influence the behavior of squirrels in Berlin. Another important aspect is the role of squirrels as seed dispersers. For this purpose, she analyses the squirrels diet.

The research aims to develop sustainable measures for wildlife management in urban areas. The results will not only serve as a basis for long-term research projects, but also as a source of information for interested citizens.
