I am generally interested in functional ecology and its relevance for interspecific interactions with a focus on sensory ecology, roosting ecology, and tropical biology. For my research I am applying a broad variety of methodological approaches such as bioacoustics, population genetics, and stable isotope analyses. Furthermore, I am trying to improve processes to communicate and share scientific knowledge with the public. A selection of my research interests can be found below.
Mutualistic interactions are major drivers of evolution. However, how they evolve and which mechanisms stabilise them is largely unknown. Using the interaction between the foliage-roosting bat species Kerivoula hardwickii and their mutualistic plant partner Nepenthes hemsleyana as a model system, I am testing different hypothesis regarding functional traits of both partners that stabilise their interaction. During my PhD (submitted) I focused on morphological, communicational and behavioural traits. The mutualism is asymmetric: The pitcher plants strongly rely on the bats, whose faeces are the most important nutrient source for the plants. This coprophagous nutrient acquisition strategy seems to be so efficient that the plants gave up important traits of arthropod attraction and outsourced capturing and pre-digestion of prey to their bat partners. The bats, in contrast, are less depending on N. hemsleyana as they additionally roost in other pitcher plant species and in developing furled leaves of different plant species. Together with my international collaborators I found that this asymmetric dependency is reflected in the specifity and function of the traits that stabilize the mutualism in each of the two involved species. Especially on the morphological level, N. hemsleyana seems to have evolved several traits that perfectly fit to K. hardwickii (i.e. a pitcher shape and fluid level that perfectly fits to the solitary roosting bats and an echoreflecting structures that is highly effective in attracting the echolocating bats resulting in high-quality roosts). In contrast, the bats’ traits more generally facilitate their roosting in funnel-shaped plant structures and their occurrence in cluttered habitats (i.e. broadband echolocation calls with extraordinary high starting frequencies and morphological traits that facilitate in slippery plant structures).Thus, they are probably exaptations (i.e. traits that evolved for another reason) that are nevertheless functional and stabilise the mutualism with N. hemsleyana. This plant‘s superior roost quality is likely a consequence of the competition with alternative roosting plants and helps N. hemsleyana that the bats prefer it. Moreover, my study confirms earlier findings that asymmetric dependencies support the stabilisation of mutualistic interactions. Finally, my work indicates that the specifity of functional traits can be used as a measure to determine mutual dependencies of mutualistic partners. In a future project I will transfer my predictions to the interaction between ants (Camponotus spp.) and the rattan palm Korthalsia robusta.
Many bat species regularly need to find new day roosts that, e.g., offer protection from predators and adverse climatic conditions.It has been shown that bats exchange information about roosts among colony members, and use echolocation and social calls of conspecifics in order to find roosts. However, how bats initially find new roosts and the role of inter- and intraspecific communication (including eavesdropping) still presents a puzzle. Investigating the sensory traits of various bat species that use different roosts (e.g., tree holes, bat boxes, furled leaves, carnivorous pitcher plants) in different regions (Germany, Borneo, Costa Rica) and using playback experiments my collaborators and I try to shed light on that field of bat ecology.
In recent years skepticism against scientific findings has been raised by broad parts of society. Academia has been called to raise awareness to this trend and to leave its ivory tower where science is only shared among experts. One solution to this problem is "Citizen Science" that invites interested citizens to participate in the process of gaining new scientific knowledge. However, in many projects Citizen Scientists were only involved in data collection but had no chance in participating the whole scientific process, i.e. observation, raising questions, building hypothesis and trying to answer the questions on basis of collected data. With our project "FUN" we are trying to close that gap. This project aims at various groups of age and societies. Thus, we are also collaborating with schools that are interested in testing teaching concepts that focus on the scientific practice.
