Results from model‐based inference from an integrative modeling approach that generates spatially explicit expectations that are tested with approximate Bayesian computation contrasts with those from correlative analyses, highlighting the importance of expanding the landscape genetic perspective to tests the links between pattern and process.
Impact of Plio‐Pleistocene arid cycling on the population history of a southwestern Australian frog
Phylogeographical analyses identified several dispersal routes, possible refugial areas within the range of the species and also regions of secondary contact, which may now be closed to the species because of habitat destruction and salinity problems in inland regions, posing concerns about the evolutionary potential of thespecies in light of predicted climate change.

Critically analyse datasets with explicit supporting phylogenetic data and estimates of the time since divergence for all available elements of the terrestrial fauna and compare these datasets to those available for plants, and derive four testable models of historical biogeography for animal taxa in SWWA.

A methodological framework combining multivariate and clustering techniques that uses genetic, morphological and ecological data to detect and assign individuals to putative species and recovers a similar number of species recognized using traditional, qualitative taxonomic approaches that are not detected when using purely genetic methods.
Effect of sperm concentration, medium osmolality and oocyte storage on artificial fertilisation success in a myobatrachid frog (Limnodynastes tasmaniensis).
Oocytes stored in 5 mOsm kg(-1) solutions showed no significant decline in fertilisability after 2 h, showing that swelling of the jelly surrounding the eggs does not prevent sperm from fusing with the oocyte in this species.
Climatic fluctuations shape the phylogeography of a mesic direct‐developing frog from the south‐western Australian biodiversity hotspot
Assessment of phylogeographic pattern throughout the range of Metacrinia nichollsi is carried out in order to develop specific biogeographical hypotheses for the wet forests of south‐western Australia.

An mtDNA dataset consisting of 1462 base pairs for 61 individuals from 13 islands produced a well-resolved phylogenetic hypothesis supported by high bootstrap values and posterior probabilities within Brachylophus, and a clade of animals in this clade is described as a new species of Brachylphus based on molecular and morphological data.
Description of a New Galapagos Giant Tortoise Species (Chelonoidis; Testudines: Testudinidae) from Cerro Fatal on Santa Cruz Island
DNA characters that define this new species are identified, and evolutionary relationships relative to other species of Galapagos tortoises are inferred.
Giant tortoise genomes provide insights into longevity and age-related disease
The genomes of two long-lived giant tortoises, including Lonesome George, reveal candidate genes and pathways associated with their development, gigantism and longevity and expands the understanding of the genomic determinants of ageing.
Effects of vicariant barriers, habitat stability, population isolation and environmental features on species divergence in the south‐western Australian coastal reptile community
The results show that patterns of genetic variation reflect complex and species‐specific interactions related to the spatial distribution of habitats present currently and during repeated glacial minima, as opposed to being associated with historical factors such as habitat stability between glacial and inter‐glacial periods or vicariant barriers.
