Research conducted by staff and postgraduate students encompasses a broad spectrum of projects on tropical animals inhabiting a variety of terrestrial, freshwater and marine environments. Emphasis has been placed on research into whole animals, e.g. their ecology, ecophysiology, evolution and behaviour and the ecosystems containing them, but opportunities also exist for investigations at the sub-organism level in certain fields, such as nutritional physiology and DNA techniques for determining genetic relationships.
Particular research strengths lie in the following subject and topic areas:
Animal Behaviour
Social behaviour in birds.Dragonfly behaviour.
Behavioural organisation in social insects.
Animal Ecology
The structure and distribution of rainforest and savanna faunal communities.Autecological studies on tropical marsupials and rodents.
Ecology of tropical bird communities.
Ecology of reptiles and amphibians.
Ecophysiology
Ecophysiology of vertebrates especially reptiles.
Entomology
Insect/plant interactions.Seasonality in tropical insects.
Freshwater Biology
Ecology of tropical streams and wetlands.Biology of tropical frogs and fish.
Ecological interactions of introduced species with native freshwater communities.
Taxonomy of tropical freshwater insects.
Population dynamics and dispersal of cane toads.
Ecology of mosquito and snail vectors of disease.
Development of biological monitoring for aquatic ecosystems.
Parasitology
Evolutionary relationships among parasites.Ecology of parasites in local amphibians.
Parasite systematics and genetics.
Tropical Biodiversity
Determinants of biodiversity in tropical rainforest communities (freshwater fauna, terrestrial invertebrates and vertebrates).Taxonomy and systematics of rainforest species.
Wildlife Conservation and Management
Effects of vegetation structure and fragmentation on small mammal communities.Classification of tropical wetlands.
Monitoring and survey methodology; environmental impact assessment.
Population studies towards conservation and management of threatened species.
Population genetics of endangered species.
Evolutionary Biology
Ecological, behavioural and genetic influences on geographic variation and natural selection.The function, ecology and evolution of animal colour patterns and vision.
