Helena Wirta - Visiting Researcher

E-mail: helena.wirta@helsinki.fi

I am interested in ecological communities from various perspectives: what taxa they consist of, how are they structured, how they function and how did they form to what they are as well as how they change.

My research currently focuses on pollination communities. My main project examines honeybees and their interactions with microbes and flowers, assessing how these communities and interactions change and how they are formed, using DNA based identification.

Alyssa Cirtwill - Postdoctoral Researcher

E-mail: alyssa.cirtwill@helsinki.fi

My main research interests are how we can describe the ways species fit into ecological networks and what the network perspective can add to our understanding of ecology. I am currently investigating how phenological change in plants and insects affects pollination networks, including crops that we humans depend on. I am also interested in how we can draw better conclusions from messy and missing data.
