Hypothesis

Can a single colonization event lead to a stable population that resists further invasions?

Conclusion

The study suggests that the initial colonization of the Kerguelen Archipelago by house mice has resulted in populations that are resistant to further invasions.

Supporting Evidence

  • Most mice on Kerguelen share the same mitochondrial haplotype.
  • Two small islands show different mitochondrial haplotypes but share a major Y-chromosomal haplotype.
  • The genetic data suggest that the mice from both primary invasions originated from related source populations.

Takeaway

Mice that first arrived on the Kerguelen Islands have made it hard for new mice to come in and take over.

Methodology

The study involved typing 18 autosomal and six Y-chromosomal microsatellite loci and obtaining mitochondrial D-loop sequences from mouse samples.

Limitations

The study's sampling was limited to specific islands and may not represent all populations.

Participant Demographics

The study focused on house mice (Mus musculus domesticus) from various islands in the Southern Ocean.
