Hard work at high latitudes...Photo: Anne LiljendahlI am a PhD student in ARKTIS Graduate School located in Rovaniemi, albeit I am working de facto in ECRU. In my Masters thesis I studied aquatic ecosystem changes during the past few hundred years in two small subarctic lakes in Kilpisjärvi region using paleolimnological approaches. I used the remains of cladocera from lake sediments as proxies, and evaluated the role of climate driving the observed development in these lakes. During my Master thesis I got sucked into the world of paleoscience and arctic global change issues, within which I will continue working in my PhD research.
My current studies will focus on development of aquatic environments in general and, in particular, the foodwebs of subarctic lakes in Northern Finland during the Holocene. I will address the multiple factors that influence present cladoceran communities in these lakes, and hence the subfossil assemblage they leave to the sediments for paleolimnological interpretation.
