Research Project

Title: Detecting tipping points in lake ecosystems

Description: Lake ecosystems can abruptly shift from one steady state to another, sometimes crossing hysteretic tipping points and resulting in regime shifts. Past research has shown that early warning signs can anticipate tipping points, offering ecosystem managers an opportunity to reverse the adverse lake conditions. However, the techniques used to detect EWS remain ambiguous, especially in relation to using palaeoenvironmental techniques. This project aims to develop research analysing how structural changes of chironomid communities can be used to detect changes in ecosystem resilience, especially in relation to past climate change. 

Funding agencies: This project is funded by a studentship provided by the SPITFIRE NERC Doctoral Training Programme at the University of Southampton, with fieldwork and laboratory analyses being supplemented by Norwegian Research Council project EGOGEN, in collaboration with Tromsø University Museum.
