Regional conservation genomics: insights and opportunities from northern Australia Open
Biodiversity conservation in northern Australia is characterised by high endemism, data deficiency, and high Indigenous land tenure and population. The Northern Australia Conservation Genomics Forum brought together experts to explore curr…

Conservation macrogenetics reveals the potential hidden consequences of the 2019-2020 Black Summer fires on Australian biodiversity Open
The use of genetic analyses has become ubiquitous in conservation planning and management as biodiversity is increasingly threatened globally. Typically, such analyses are employed at the species-level, though as genetic data accrue, it is…

Chromosome evolution and speciation: Revisiting Bush et al. (1977) Open
Whether and how chromosome change can drive speciation has long attracted the interest of evolutionary biologists. In a seminal paper, Bush et al. (1977) demonstrated wide variation in rates of macroscopic chromosome change across vertebra…

Pleistocene climatic changes drive expansion and fragmentation in a widespread arid zone specialist, Petrogale lateralis Open
Organisms living in arid biomes are predicted to be at threat of extinction associated with ongoing climatic and anthropogenic change. Our understanding of species responses to Pleistocene climatic changes within these environments is stil…

Unrecognized lineages transform our understanding of diversification in a clade of lizards Open
Evolutionary lineages at the tip of the tree of life can be genetically diverged yet phenotypically similar and therefore unrecognized by traditional morphology-based taxonomy. Such lineages, spanning the “grey zone of speciation” 1, are i…

Molecular systematics of the Dendrolagus goodfellowi species group (Marsupialia: Macropodidae) Open
Tree-kangaroos (genus Dendrolagus) are a morphologically distinctive genus of specialized, arboreal macropodids confined to the wet forests of New Guinea and northeast Australia. A distinct Goodfellow’s group, containing up to four species…

Museum Skins Enable Identification of Introgression Associated with Cytonuclear Discordance Open
Increased sampling of genomes and populations across closely related species has revealed that levels of genetic exchange during and after speciation are higher than previously thought. One obvious manifestation of such exchange is strong …

Functionally mediated cranial allometry evidenced in a genus of rock-wallabies Open
In assessments of skeletal variation, allometry (disproportionate change of shape with size) is often corrected to examine size-independent variation for hypotheses relating to function. However, size-related trade-offs in functional deman…

The importance of appropriate taxonomy in Australian mammalogy Open
The use of correct taxonomy to describe and name the earth’s biodiversity is fundamental to conservation and management. However, there are issues that need to be overcome to ensure that the described taxa and their scientific names are bo…

Sequence Capture From Historical Museum Specimens: Maximizing Value for Population and Phylogenomic Studies Open
The application of high-throughput, short-read sequencing to degraded DNA has greatly increased the feasibility of generating genomic data from historical museum specimens. While many published studies report successful sequencing results …

Future‐proofing the koala: Synergising genomic and environmental data for effective species management Open
Climatic and evolutionary processes are inextricably linked to conservation. Avoiding extinction in rapidly changing environments often depends upon a species’ capacity to adapt in the face of extreme selective pressures. Here, we employed…

Limited Introgression between Rock-Wallabies with Extensive Chromosomal Rearrangements Open
Chromosome rearrangements can result in the rapid evolution of hybrid incompatibilities. Robertsonian fusions, particularly those with monobrachial homology, can drive reproductive isolation amongst recently diverged taxa. The recent radia…

Understanding Historical Demographic Processes to Inform Contemporary Conservation of an Arid Zone Specialist: The Yellow-Footed Rock-Wallaby Open
Little genetic research has been undertaken on mammals across the vast expanse of the arid biome in Australia, despite continuing species decline and need for conservation management. Here, we evaluate the contemporary and historical genet…

Chromosomics: Bridging the Gap between Genomes and Chromosomes Open
The recent advances in DNA sequencing technology are enabling a rapid increase in the number of genomes being sequenced. However, many fundamental questions in genome biology remain unanswered, because sequence data alone is unable to prov…

A Framework for Resolving Cryptic Species: A Case Study from the Lizards of the Australian Wet Tropics Open
As we collect range-wide genetic data for morphologically-defined species, we increasingly unearth evidence for cryptic diversity. Delimiting this cryptic diversity is challenging, both because the divergences span a continuum and because …

Phylogenomics of a rapid radiation: the Australian rainbow skinks Open
The application of target capture with next-generation sequencing now enables phylogenomic analyses of rapidly radiating clades of species. But such analyses are complicated by extensive incomplete lineage sorting, demanding the use of met…

A new genus to accommodate three skinks currently assigned to Proablepharus (Lacertilia: Scincidae). Open
The genus Proablepharus currently contains five species (P. barrylyoni, P. kinghorni, P. naranjicaudus, P. reginae and P. tenuis). Morphologically, these are readily separated into two groups: the small, almost patternless species (P. regi…

Real‐world conservation planning for evolutionary diversity in the Kimberley, Australia, sidesteps uncertain taxonomy Open
Targeting phylogenetic diversity (PD) in systematic conservation planning is an efficient way to minimize losses across the Tree of Life. Considering representation of genetic diversity below and above species level, also allows robust ana…

Analysis of Phylogenomic Tree Space Resolves Relationships Among Marsupial Families Open
A fundamental challenge in resolving evolutionary relationships across the tree of life is to account for heterogeneity in the evolutionary signal across loci. Studies of marsupial mammals have demonstrated that this heterogeneity can be s…

Gene flow despite complex Robertsonian fusions among rock-wallaby ( <i>Petrogale</i> ) species Open
Complex Robertsonian rearrangements, with shared arms in different fusions, are expected to prevent gene flow between hybrids through missegregation during meiosis. Here, we estimate gene flow between recently diverged and chromosomally di…
