Keynote speakers

We are pleased to confirm the following keynote speakers at ESA20

Dr Gretta Pecl, Institute for Marine and Antarctic Studies (IMAS), Tas.

Gretta Pecl is a Professor of marine ecology at the Institute​ for Marine and Antarctic Studies (IMAS)​, and the Director of the Centre for Marine Socioecology (CMS), which leads the Future Seas collaboration project (, both located in Tasmania, Australia. She is a marine ‘generalist’ with broad interdisciplinary research interests, building on a background in population dynamics, fisheries biology, and movement and migration of commercial species. She currently focusses on species and ecosystem responses to climate change, and the development of adaptation options for natural resource management. She has a specific interest in exploring the mechanisms and processes underpinning climate-driven species redistribution, and the ecosystem implications of these, including co-convening the 2016 & 2019 ‘Species on the Move’ conferences ( One of the approaches she uses to examine climate-driven changes in species distribution includes citizen science; she developed and leads the National citizen science project Redmap Australia, the Range Extension Database and mapping project, which invites fishers and divers around our coastline to help monitor changes in Australian seas. Gretta has a strong passion for science communication and engagement with the public. She is also a Lead Author for the IPCC AR6 report, an Australian Research Council ‘Future Fellow’ and an associate editor for Reviews in Fish Biology and Fisheries, Ecography and Citizen Science Theory & Practice.

Professor Adrienne Nicotra, Australian National University, ACT

Prof Adrienne Nicotra is a plant evolutionary ecologist with interest in the capacity of plants to respond to environment and environmental change –phenotypic plasticity. Her work focusses on native species from a wide range of environments, though she is particularly fond of mountain flora. Adrienne joined ANU as a postdoctoral fellow in 1998 and has been there ever since, now as a Professor in the Division of Ecology and Evolution in the Research School of Biology. In addition to her research work, Adrienne teaches, supervises honours and postgraduate students and is the director of the Australian Mountain Research Facility (
