Quest 03 / Population scale

Species biogeography and evolution in island systems

How do isolation, movement, and environment shape diversity across island populations?

Island honey bees reveal how colonization history, admixture, local environments, and human-mediated movement structure biodiversity across archipelagos.

RESEARCH BACKGROUND

Why this system?

Islands are natural systems for examining movement, isolation, admixture, and environmental differences. Their geographic boundaries help connect colonization history to present-day genomic variation without assuming that every difference is adaptive.

QUESTIONS / SYSTEMS / APPROACH

From biological observation to evolutionary mechanism.

Guiding questions

  1. 01

    How do colonization history and connectivity structure diversity across islands?

  2. 02

    When does human-mediated movement reinforce or reduce geographic differentiation?

  3. 03

    Which genomic patterns remain after demographic history is considered?

Biological systems

  • Honey bee populations across island systems
  • Managed and feral populations connected by movement
  • Archipelagos with contrasting ecological and colonization histories

Approaches

  • Population and landscape genomics
  • Biogeographic and demographic reconstruction
  • Comparative sampling across islands
  • Tests of gene flow and admixture

NEXT QUESTIONS
