Research Interests

Proximate Mechanisms of the Interactions between Bats (Kerivoula hardwickii) and Carnivorous Pitcher Plants (Nepenthes)

Mutualistic interactions are major drivers of evolution. Since 2009 I am researching on the interaction between bats and pitcher plants on Borneo. The small bat species Kerivoula hardwickii is roosting in the pitcher-like trapping organs of carnivorous plants. With one of these pitcher plants (Nepenthes hemsleyana) the bat is maintaining a symbiosis: while the bat has a safe place to sleep, the plant gains nutrients (e.g. nitrogen, potassium, phosphate) from the bats’ feces. This mutualism requires certain mechanisms so that both partners are able to interact with each other: Both the pitchers and the bats occur in vegetation-dense peat swamp forests and are rare. Nepenthes hemsleyana needs a balanced height of their digestive fluid so that bat roosting is possible and not conflicting with nutrient uptake. The bats have to stick inside the pitchers without injuring the plants too much. Thus, I am raising the following questions: Which traits of the bats and the pitcher plants enable their gathering? Do both partners show morphologies, which facilitate their interactions but are missing in closely related species? In which ways are the bats interacting with different pitcher plants (symbiosis, commensalism, parasitism)? To find answers, I am using methodologically broad approaches including non-invasive in-situ experiments, bioacoustics, radio-telemetry or morphological comparisons. My research shall provide new insights into mutualistic mechanisms and raise the awareness for fragile ecosystems like Borneo’s peat swamps.

Further Research Projects

Another project I've been involved is the question how to reduce the mortal impact of wind turbines on bats. This long-term project is conducted by the University of Erlangen.

Coordination

Moreover, I am coordinating the DFG graduate School GRK2010 "RESPONSE - Biological RESPONSEs to Novel and Changing Environments" and the central education programme of teachers (stand-in for parental leave).
