Tornos, J., Biovac, C. (2019). Exploring what movements matter in a critical eco-epidemiological situation, the case of avian cholera in seabirds of Amsterdam island.
Abstract: Introduction: Infectious Diseases Can Be A Threat For Wild Populations And The Spatialecology Of These Diseases Need To Be Explored To Understand How Infectious Agents Circulatein Spatially Structured Ecosystems Such As Islands. On Amsterdam Island (Southern Indianocean), Pasteurella Multocida, The Bacteria Responsible For Avian Cholera, Causes Recurrentmortality Of Albatross And Penguin Chicks. Different Types Of Movements Of Individuals, Fromforaging To Migration And Prospecting, Could Play A Major Role In The Circulation Of The Infectious Agent At Different Scales.objectives: The Main Purpose Of This Study Is To Evaluate The Potential Role Of Differentspecies In The Dissemination Of P. Multocida With A Combined Study Of Movement Ecologyand Eco-epidemiology.methods: We Considered Potentially Involved Behavioral Processes Such As Foraging Movements Of Brown Skuas (Stercorarius Antarcticus) And Within-season Prospecting Movementsof Indian Yellow-nosed Albatrosses (Thalassarche Carteri). We Deployed Uhf-gps Loggerson Breeding Skuas And Non-breeding Albatrosses During Avian Cholera Outbreaks.results: We Show That The Skuas Spent An Important Time In The Colonies Of Albatrossesand In Different Places Around The Island, But Did Not Hold Feeding Territories. In Addition,we Found Very High Seroprevalence And Titers Of Antibodies Against P. Multocida Among Thesampled Individuals, Suggesting That They Could Play An Important Role In The Circulation Ofthe Infectious Agent. We Also Show That Indian Yellow-nosed Albatrosses In Breeding Failureor Pre-breeding Individuals Can Visit Different Conspecific Colonies On The Island, Suggestingthey Could Also Play A Role In The Spread Of P. Multocida Among Breeding Patches Of Thislocally Abundant But Threatened Species.conclusion And Implications: Our Study Identifies Various Movements That May Be Involvedin Eco-epidemiological Dynamics In Multi-host/parasite Systems And That Their Careful Characterization Is Important For Basic And Applied Reasons.
