Migration-driven microbial adaptation and ecological spillover in birds.

Area of Science:

• Ecology
• Microbiology
• Animal Physiology

Background:

• Migratory birds face extreme physiological stress, relying on gut microbiota for energy and immunity.
• Gut microbial communities in birds shift with diet and environment during migration.
• Birds can transmit zoonotic diseases and antimicrobial resistance genes via their gut microbes.

Purpose of the Study:

• To explore the role of gut microbiota in bird migration.
• To understand how microbial communities change during migration and their impact on performance.
• To identify risks associated with microbial exchange at stopover sites.

Main Methods:

• Longitudinal sampling of migratory birds.
• Meta-omics analyses to study microbial composition and function.
• Controlled experiments to investigate host-microbe interactions.

Main Results:

• Gut microbiota composition and function change dynamically during migration.
• Microbiota shifts can impact nutrient absorption and immune function.
• Stopover sites facilitate microbial exchange, increasing disease transmission risks.

Conclusions:

• Gut microbiota is crucial for migratory bird adaptation and performance.
• Further research is needed to understand microbiota dynamics and their link to migration.
• A One Health approach is essential for managing risks associated with migratory birds and their microbes.
