Data from: Island size shapes genomic diversity in a great speciator (Aves: Zosterops)

Islands have long represented natural laboratories for studying many
aspects of ecology and evolutionary biology, from speciation to community
assembly. One aspect that has been well documented is the correlation
between island size and taxonomic diversity, likely due to decreased
complexity and population size on small islands. This same logic can apply
to genetic diversity, which should predictably decrease with effective
population size. The island size-diversity correlation has received
support over the years, but often focuses on simple metrics of genetic
diversity. Here, we use Zosterops white-eyes in the Solomon Islands to
study the correlation between island size and various metrics related to
genetic diversity, including runs of homozygosity and fixation of
transposable elements. We find that almost all of these metrics strongly
correlate with island size, and in turn with each other. We infer that
island size is independently correlated with these different variables,
demonstrating that population size impacts genomic metrics of diversity in
a variety of ways across temporal and hierarchical scales.
