IAN JONES, PhD is a physical limnologist in the Biological and Environmental Sciences Division at the University of Stirling (UK), having previously worked for many years at the UK’s Centre for Ecology & Hydrology in Lancaster and, before that, the School of the Environment at the University of Leeds (UK). As well as physical limnology studies, his research has focussed on the interaction between lake physics and the biology and chemistry in lakes, studying interactions with phosphorus, carbon, oxygen, bacteria, charophytes, phytoplankton, zooplankton, and fish. Jones has been working with in situ high-resolution lake data for more than 20 years as well as a variety of physical and biological numerical models.JOHN P. SMOL, OC, PhD, FRSC, FRS is a Distinguished University Professor in the Department of Biology at Queen’s University (Canada). Smol founded and co-directs the Paleoecological Environmental Assessment and Research Lab (PEARL), a group of ~40 students and other scientists dedicated to the study of long-term global environmental change, and especially as it relates to lake ecosystems. John has authored >660 journal publications and chapters, as well as completed 22 books. Smol was the founding Editor of the J. Paleolimnology (1987-2007) and is current Editor of Environmental Reviews (2004 – present). Since 1990 he has received six honorary doctorates and has been awarded >70 research and teaching awards and fellowships, including the International Society of Limnology Naumann-Thienemann Medal, both the Hutchinson Award and the Margalef Award from the Association for the Sciences of Limnology and Oceanography, the International Ecology Institute Prize, and the NSERC Herzberg Gold Medal as Canada’s top scientist or engineer. He was named an Officer of the Order of Canada for his environmental work, a Fellow of the Royal Society (London), and was elected President of the Academy of Science, Royal Society of Canada (2019-2022).
