Biography

Aaron Potito photo

My research focuses on the use of biological indicators in lake sediments and tree-rings to reconstruct late Pleistocene and Holocene climates and to assess human impacts on lake and forest environments. My research has increasingly concentrated on chironomid (non-biting midge fly) subfossils in lake sediments as a palaeoenvironmental indicator, but I remain active in dendroecological and dendroclimatological studies. Current chironomid-based research interests include palaeotemperature reconstruction for Holocene climates in Ireland, assessment of historical and pre-historical human impacts on lake systems in Ireland, and the study of recent human impacts on lake ecosystems in China. Dendrological research interests include the use of tree ring techniques to assess the health and growth patterns of natural forest stands in western Ireland. My work has been based in the United States, Ireland, and China.

Research Interests

Palaeoclimatology - Palaeolimnology - Chironomids - Tree rings - Climate change - Holocene

Collaborative Interests

I am interested in collaborating on palaeoenvironmental studies using lake sediments, where I can offer my chironomid expertise as part of a multi-proxy investigation. I am interested in Holocene and Late Glacial studies, as well as more recent changes to lake systems due to human impacts and climate change.
