I come from Estonia, where I
completed my undergraduate and graduate studies at the University of Tartu. For my PhD thesis in the Macroecology workgroup I studied plant population
response to habitat fragmentation and degradation in semi-natural calcareous
grasslands, looking at how historical and current landscape structure and human
effect in combination with current environmental conditions determine the
population condition in remnant grasslands and to detect delayed responses to
landscape changes.
Here at the University of the Aegean
I have now turned focus on the effect of climate change on plant-pollinator
interactions in Mediterranean communities. I study changes in plant nectar and
pollen production under experimental conditions, involving multiple plant
species. Also I am interested in the effect of wildfires on pollinator
diversity.
In addition to science I enjoy reading,
hiking and doing handicraft.
