My research focuses on climate change effects on mountain lakes.
The long-term ecological research site Lake Tovel (LTER, IT 09–005-A) is my focal study site. Lake Tovel is a climate sentinel for the over 300 lakes of the Trentino province.
To uncover the manyfold and complex interactions between plankton or lake physics and climate change, I am using traditional techniques (classical monthly sampling covering key environmental parameters) and innovative techniques (environmental DNA, sensors [temperature, oxygen, light, water level, conductivity], isotopes [O18, dH1]). For statistical analyses, I am using the open-source software R and I am applying Bayesian and frequentists models. I am an expert on the ecology and taxonomy of rotifers, a necessary condition to study the plankton of Lake Tovel.
The combination of traditional and innovative techniques allows me to get a holistic view on on-going biogeochemical processes in an aquatic lake ecosystem.
Key words of my research are physical limnology, lake metabolism, functional ecology, mixing processes, plankton ecology, and winter limnology.
