Movement patterns and behavioural strategies of Estuarine Crocodiles: A long-term remote monitoring study using an underwater acoustic array. The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public.

The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public. Knowledge of where crocodiles go, what they do when they get there, and why they select particular habitats at certain times is critical for sustaining the Australian crocodile population, whilst ensuring public safety. This long term study will utilise the latest advancement in underwater acoustic technology to monitor the behavioural and physiological strategies used by estuarine crocodiles in occupying critical habitats, providing vital information for resource managers and policy makers.

Summary
Did colour vision evolve in the dark? This project aims to investigate the ability of fishes to perceive colour in dim-light conditions by studying representatives from two delicate and endangered ecosystems, coral reefs (nocturnal fish) and the deep-sea. Through a multidisciplinary approach to understanding colour vision and animal behaviour, this study expects to fill a knowledge gap in visual neuroscience and ecology while adding to the understanding of how marine creatures see and interact. ....Did colour vision evolve in the dark?

Through a multidisciplinary approach to understanding colour vision and animal behaviour, this study expects to fill a knowledge gap in visual neuroscience and ecology while adding to the understanding of how marine creatures see and interact. This should provide benefits in conservation and management strategies and may also inspire the development of new sensor technologies.Read moreRead less

Outcomes beyond multiple scientific disciplines include enhanced international collaboration and building capacity for improved reef guardianship. The benefits are scientific discovery in multiple areas, providing greater community understanding of complex science and a desire to preserve the GBR for future generations.Read moreRead less
Evolutionary roots of social bonds in female mammals. The social networks and friendships of wild female kangaroos and how these benefit individuals will be studied. This project will help us understand how the propensity of mammals to form friendships evolved; this understanding of the evolutionary roots of friendships will help in understanding why friendships affect peoples' health and mortality.

This project aims to reveal how the visual systems of marine creatures from the Great Barrier Reef receive and interpret colour and polarisation information, much of which is invisible to the human eye. It aims to utilise this data to tackle fundamental questions in neuroscience and inform bio-inspired camera design and machine-vision solutions. The resulting new generation of polarisation cameras will be used to characterise the environments, animals and brains that inspired them in the first place. This will help the understanding of how nervous systems convey information and may improve our ability to detect dysfunction in neurons and other cells.Read moreRead less
Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear f ....Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear for resident fishes, via chemical interference emanating from degraded coral. Inter-generational advantages would help management to regulate reef usage to promote resilience.Read moreRead less
Stomatopods v Cephalopods: discovery from an information coding arms-race. This proposal aims to unlock the power of a 400 million year old evolutionary arms race between two of earth's most successful predators, cephalopods (e.g. octopus) and mantis shrimp (stomatopods). New knowledge in vision (sensor design), neural coding (circuits and information flow) and behavioural (decisions and actions) innovations from these two groups will have fundamental and applied outcomes. The interdisciplinary ....Stomatopods v Cephalopods: discovery from an information coding arms-race. This proposal aims to unlock the power of a 400 million year old evolutionary arms race between two of earth's most successful predators, cephalopods (e.g. octopus) and mantis shrimp (stomatopods). New knowledge in vision (sensor design), neural coding (circuits and information flow) and behavioural (decisions and actions) innovations from these two groups will have fundamental and applied outcomes. The interdisciplinary and comparative nature of the project aims to amplify outcomes in questions of efficient neural coding, optical design and bio-inspired solutions. Benefits from the study include GPS-free navigation in marine engineering and rapid exposure of research results to millions of people through existing communication programs. Read moreRead less
New dimensions in colour and polarisation vision on The Great Barrier Reef. Many animals possess colour vision that outperforms humans and some also have a type of vision we lack altogether, polarisation vision. By comparing design and discovering strategies from the sensory systems of animals on The Great Barrier Reef, the project will enhance our knowledge of their sensory world, their ecosystem and broader visual neuroscience.
How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aim ....How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aims to fill this knowledge gap specifically it endeavours: to provide useful tools for behavioural ecologists and visual neuroscientists, and to understand for the first time the full gamut of colour signalling in both terrestrial and aquatic environments.Read moreRead less
The functions of reef fish colour patterns: how did the coral trout get its spots? How did the coral trout get its spots? Why are some reef fish striped yellow and blue while others dress in pink and orange blotches? This project goes beyond just interpreting animal colours and uses a new approach to reveal the meanings of whole body patterns. Uniquely, it does so through the eyes of the fish themselves.
