Does malaria infection increase the risk of predation-related mortality during bird migration? Gangoso De La Colina, Laura Esther Santamaría Cervantes, Claudia Martínez de la Puente, Josué Ruiz López, María José Figuerola, Jordi The migratory culling hypothesis posits that infected individuals are less likely to survive long-distance migration due to physiological and behavioral effects, but this lacks empirical evidence. Here, we tested this hypothesis by sampling 357 passerines from 11 species during their autumn migration to wintering grounds in two different areas, i) at a stopover in southern Spain, and ii) in the Canary Islands, where they were drifted and preyed upon by Eleonora’s falcons while en route to the southern Sahara. Molecular detection of infections by Plasmodium, Haemoproteus, and Leucocytozoon was conducted on bird samples. A higher prevalence of both Plasmodium and Haemoproteus was observed in birds preyed upon by falcons. While a complete understanding of the mechanistic effects of haemosporidian infections on migration performance needs experimental validation, our approach suggests that infection reduces migration success by increasing mortality due to route deviations and/or predation. 2025-01-29T13:19:59Z 2025-01-29T13:19:59Z 2025-01-29T13:19:59Z 2024-12-20 journal article https://hdl.handle.net/20.500.14352/116907 2589-0042 10.1016/j.isci.2024.111358 eng info:eu-repo/grantAgreement/Cabildo de Lanzarote/8023/2023 info:eu-repo/grantAgreement/MICINN/Plan Estatal de Investigación Científica y Técnica y de Innovación 2020-2023/CNS2022-135873/Comprendiendo las respuestas fenotípicas al cambio ambiental: el papel de la variación genética y su relación con la plasticidad en la respuesta al estrés ambiental info:eu-repo/grantAgreement/MICINN/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PID2020-118205GB-I00/Efectos de la microbiota del mosquito en la transmisión de patógenos aviares info:eu-repo/grantAgreement/MICINN/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PID2020-118921RJ-100 info:eu-repo/grantAgreement/MICINN/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PID2021-123761OB-I00/Comprendiendo la ecología de los vectores del Virus West Nile para reducir el riesgo de transmisión a humanos info:eu-repo/grantAgreement/Junta de Andalucía/ P21_00049 Gangoso, L., Santamaría-Cervantes, C., Martínez-de la Puente, J., Ruiz López, M.
