Islands promote diversification within the silvereye clade: a phylogenomic analysis of a great speciator

This study uses phylogenomic analysis to show that islands promote population divergence in silvereye birds, supporting the role of geographic isolation in speciation.

Standing genetic variation and de novo mutations underlie parallel evolution of island bird phenotypes

The paper investigates the genetic basis of parallel evolution in island silvereye birds, finding both de novo mutations and standing genetic variation contribute to body size changes.

Candidate gene length polymorphisms are linked to dispersive behaviour: searching for a mechanism behind the "paradox of the great speciators"

The study investigates genetic associations between dispersal behavior and six candidate genes in silvereye populations, finding links between allele length variations and dispersal propensity.

Density dependent environments can select for extremes of body size

The paper develops size-structured models to explore how density dependence influences body size evolution, showing that gigantism or dwarfism depends on population maturity proportions and developmental trajectories.

The genomic landscape of divergence across the speciation continuum in island-colonising silvereyes (Zosterops lateralis)

This study uses RAD-sequencing and simulations to analyze genomic divergence in silvereyes, finding limited support for genomic islands widening with time and divergence accumulating around selected loci.
