The south‐western land division of Western Australia (SWWA), bordering the temperate
Southern and Indian Oceans, is the only global biodiversity hotspot recognised in Australia …

Birds exhibit remarkable variation in plumage patterns, both within individual feathers and
among plumage patches. Differences in the size, shape, and location of pigments and …

Birds are prolific colonists of islands, where they readily evolve distinct forms. Identifying
predictable, directional patterns of evolutionary change in island birds, however, has proved …

The polytypic species concept unites populations that theoretically could and would
interbreed were the opportunity to arise. This concept places the burden of proof of …

The complex island archipelagoes of Wallacea and Melanesia have provided empirical data
behind integral theories in evolutionary biology, including allopatric speciation and island …

Different models of speciation predict contrasting patterns in the relationship between the
dispersal ability of lineages and their diversification rates. This relationship is expected to be …

Todiramphus chloris is the most widely distributed of the Pacific's 'great speciators'. Its 50
subspecies constitute a species complex that is distributed over 16 000 km from the Red …

Many organisms possess multiple discrete genomes (ie nuclear and organellar), which are
inherited separately and may have unique and even conflicting evolutionary histories …

As a dispersive lineage expands its distribution across a heterogeneous landscape, it
leaves behind allopatric populations with varying degrees of geographic isolation that often …

Aim Kingfishers are the most species‐rich family in the avian order, Coraciiformes. Their
modern distribution is largely pantropical; however, global species diversity is unevenly …
