Alfred Deakin Prof. Marcel Klaassen has developed broad research interests including theoretical, experimental and observational studies on numerous animal, plant and microbe taxa. Throughout this, his focus has primarily been on bird migration, nutritional ecology and disease ecological issues.
- Modelling avian migration strategies, population dynamics and conservation strategies
- Disease Ecology and the connecting powers of migrants
- Nutritional ecology and reserve dynamics in waterfowl, waders and marsupials

Hampered foraging and migratory performance in swans infected with low-pathogenic avian influenza A virus. PLoS ONE 2007, 2:e184.
“The first behavioural ecological paper on the consequences of Avian Influenza infection in wild migratory birds, changing the thinking of many virologist, veterinarians and epidemiologist on AIV dynamics.”

“Using novel applications of stable isotope ecology and eco-immunology, we identified that the chance of becoming infected is highly related to age and the habitat choice of birds.”

“Cleverly using stable isotopes in feathers of adults and chicks, grown at various localities, we found that waders do not make eggs from nutrients deposited while migrating to the Arctic.”

“We spectacularly made a bird migrate voluntarily in a windtunnel for “6,300 km”, while meticulously measuring its energy and nitrogen balance, uniquely showing the fuel composition used in migratory flight.”

“Where empirical research is difficult, models can assist. We show how fitness consequences of environmental change vary dramatically depending on the subtle relation between environmental cue and optimal timing.”
