Stefan has broad interests in animal evolutionary biology, ecology and behaviour. Since receiving his BSc in Marine biology and Zoology in 2000 (JCU) he has been employed as a lecturer, research fellow, and environmental research consultant. In 2010 he received a PhD from JCU for his work on reef fish breeding systems and strategies. From mid 2011 to end 2013 Stefan worked as a Research Fellow at the Centre of Excellence for Coral Reef Studies using theoretical and experimental approaches to study collective-action and consensus-decision problems and the evolution of animal communication, behavioural decision rules and strategic cooperation
New research on the Great Barrier Reef associates severe coral loss with substantial increases in the size of large, long-living herbivorous fish. However, the ecosystem is also left vulnerable to cra
Though coral reefs are in sharp decline across the world, scientists say some reefs can still thrive with plentiful fish stocks, high fish biodiversity, and well-preserved ecosystem functions. An i
Australia’s iconic Great Barrier Reef is experiencing its third coral bleaching event in just five years. The 2020 bleaching is severe, and more widespread than earlier events. “We surveyed 1,0
Stunning ‘gardens’ of deep-sea corals have been discovered in the Bremer Canyon Marine Park by Australian and international scientists during an oceanographic expedition aboard Schmidt Ocean Insti
Abstract: The dynamics of metapopulations are governed by many factors, including the spatial structure of populations across the landscape, life-history characteristics, demographic processes, and t
Abstract: I will start with a brief overview of the importance of movement as an element of ecological adaptation to environmental change. I will then consider two examples, both involving birds, of
Abstract: Achieving sustainable development requires scientists, decision-makers and practitioners to understand and work with synergies and trade-offs among the social, economic and environmental co
Abstract: In this talk you will discover that my research encompasses a diverse range of projects associated with ecology and fisheries across a variety of species. As such, I will discuss the findin
Abstract: Wildlife crime is a significant global problem that undermines efforts to protect the environment, applies immense pressure to often fragile social and cultural structures and deprives econ
Abstract: The talk will provide an early account of the severity and extent of coral bleaching on the Great Barrier Reef in 2020, and how it compares with earlier mass bleaching in 1998, 2002, 2016 a
Abstract: The continuing and rapid global decline of coral reefs calls for new approaches to sustain reefs and the millions of people who depend on them. In this talk, I present ongoing work by my re
Abstract: International conflict over fishery resources is a growing security concern. Increasing incidences of conflict, diminishing fishery resources and climate impacts on marine systems have aler
