Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Describe and identify what dosimetry parameters are of importance to interpret dose-response relationships (eg., mortality, sub-lethal, growth or reproduction inhabitation, DNA damage and reactive oxygen species, etc. ) for metal-based nanoparticles? How to develop quantitative models that enable to…

‘Zelfs op het diepste punt van de oceaan kun je nog het geluid van boten horen,’ zegt bioloog Hans Slabbekoorn. ‘En dat terwijl geluid de belangrijkste vorm van communicatie is voor het onderwaterleven'. Wat betekent al die herrie in de zee voor vissen en andere dieren? Op expeditie met het onderzoeksschip…

How can mega sand nourishments, such as the Sand Motor, be designed and managed for optimal ecosystem services provision ?

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.
