Krista Takkis


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.
