Predator and scavenger movements among and within endangered seabird colonies: Opportunities for pathogen spread

摘要: 1. The spatial structure of host communities is expected to constrain pathogen spread. However, predators and/or scavengers may connect distant (sub)populations when foraging. Determining whether some individuals or populations play a prominent role in the spread pathogens critical inform management measures. 2. We explored movements and epidemiological status brown skuas (Stercorarius antarcticus), only avian terrestrial consumer native Amsterdam Island (Indian Ocean), assess how they could be involved bacterium Pasteurella multocida, which recurrently causes cholera outbreaks endangered albatross penguin species breeding on island. 3. High proportions seropositive DNA-positive for P. multocida indicated that are highly exposed able transmit it. Movement tracking revealed foraging ranges largely overlap among expand all along coasts where albatrosses penguins nest, but not inland plateau hosting endemic (Diomedea amsterdamensis). 4. Considering movement data, skua provide opportunity within seabird colonies. 5. Synthesis applications. This work highlights importance considering behaviour disease dynamics because such can potentially limit efficiency local measures spatially-structured communities. Such thus represent priority vaccination targets implement efficient aiming at limiting also used as sentinels monitor circulation evaluate effectiveness measures.
