Professor Gell is a paleoecologist who examines change in the condition of wetlands over culturally relevant timelines. He has a particular interest in contributing to a better understanding of natural ecological character under the Ramsar Convention. He specialises in the use of diatoms as indicators of present, and past, river and lake condition, particularly in coastal systems and across Australia's Murray Darling Basin. An emerging interest is the use of paleoecological approaches to reveal past instances of regimes shifts and tipping points in wetland ecosystems. He also continues his interests in the use of birds as indicators of ecosystem health. Professor Gell has written over 140 journal articles, books, book chapters and reports, is a member of the Scientific Steering Committee of the Future Earth Global Change Project PAGES (Past Global Changes) and leads its Aquatic Transitions working group. Professor Nick Davidson is an Adjunct Professor at the Institute of Land, Water and Society, Charles Sturt University, Australia, and an independent consultant on wetland conservation and wise use. His work focusses on improving the science knowledge-base for policy-relevance and decision-making at national and international scales and the implementation of wetland wise use. His current research interests focus on wetland status and trends and the status, migrations and ecophysiology of migratory waterbirds. Nick was the Deputy Secretary General of the Ramsar Convention on Wetlands from 2000 to 2014, with overall responsibility for the Convention's global development and delivery of scientific, technical and policy guidance and advice and communications, as the Convention Secretariats senior advisor on these matters. Prior to his Ramsar Convention post he worked for the UK's national government conservation agencies on coastal wetland inventory, assessment, information systems and communications, and as International Science Coordinator for the global NGO Wetlands International. He currently chairs the Society of Wetland Scientists (SWS) Ramsar Section, is an SWS International Fellow and an Honorary Fellow of the Chartered Institute of Water & Environmental Management (CIWEM). Professor Max Finlayson is an internationally renowned wetland ecologist with extensive experience internationally in water pollution, mining and agricultural impacts, invasive species, climate change, and human well-being and wetlands. He has participated in global assessments such as those conducted by the Intergovernmental Panel for Climate Change, the Millennium Ecosystem Assessment, and the Global Environment Outlook 4 & 5 (UNEP). Since the early 1990s he has been a technical adviser to the Ramsar Convention on Wetlands and has written extensively on wetland ecology and management. He has also been actively involved in environmental NGOs and from 2002 - 07 was President of the governing council of global NGO Wetlands International. He is currently on the scientific committee of the International Lake Environment Committee. Professor Finlayson has contributed to over 400 journal articles, reports, guidelines, proceedings and book chapters on wetland ecology and management. He has contributed to the development of concepts and methods for wetland inventory, assessment and monitoring, and undertaken many site-based assessments in many countries.
