Inter-oceanic variation in patterns of host-associated divergence in a seabird ectoparasite
[Aim] Parasites with global distributions and wide host spectra provide excellent models for exploring the factors that drive parasite diversification. Here, we tested the relative force of host and geography in shaping population structure of a widely distributed and common ectoparasite of colonial...

[Aim] Parasites with global distributions and wide host spectra provide excellent models for exploring the factors that drive parasite diversification.

[Location] Two natural geographic replicates of the system: numerous seabird colonies of the North Pacific and North Atlantic Ocean basins. [Methods] Using eight microsatellite markers and tick samples from a suite of multi-specific seabird colonies, we examined tick population structure in the North Pacific and compare patterns of diversity and structure to those in the Atlantic basin.
