“…Where multiple captures were recorded during the lifetime of an individual, trapping location and data from the first adult capture were used (adults were identified as animals >180 g according to Procter (2007)). DNA was then extracted from tissue by S. Barclay using the method described in Barclay et al (2006). These samples were submitted to commercial sequencing company Diversity Arrays Pty Ltd (DArT) for single nucleotide polymorphism (SNP) genotyping.…”

Dispersal behaviour and sociality are significant factors influencing survival at both the individual and population levels. In translocation and breeding programmes, social structure and sex-biased philopatry and dispersal should be considered in order to maximise population viability and conservation outcomes. Here, we use the greater stick-nest rat (Leporillus conditor), a native Australian rodent, as a case study to understand how knowledge of social structure and dispersal can inform conservation and translocation programmes. We combine high-throughput DNA sequencing with field trapping data from a translocated population of greater stick-nest rats at Arid Recovery Reserve, South Australia, to provide the first empirical evidence of female philopatry and male-biased dispersal in this species. Males were found to disperse, on average, 1.5 km from the natal nest, while females typically did not disperse beyond 500 m. Further, recapture data showed that females demonstrated a higher degree of nest fidelity than males over time. Based on these findings, we make two key recommendations for future translocations of the species. Firstly, founders should be harvested in small groups at adjacent nest sites with groups separated by a minimum of 1.5 km allowing family group structure to be retained during translocation while simultaneously maximising genetic diversity. Secondly, translocated individuals should be released in family cohorts into patches of optimal habitat that contain adequate shelter substrates interspersed over short distances (~300-500 m, the maximum dispersal distance of females found in this study), thereby facilitating nest establishment and maintenance of family groups. The results of this study have implications for conservation and reintroduction biology as a whole; we highlight the importance of considering spatial genetic structure during all stages of translocations to improve outcomes, and the value of combining genetic and field data to better understand species' social and spatial preferences.

Comparative tongue anatomy of the rakali (Hydromys chrysogaster) and greater stick-nest rat (Leporillus conditor) (Rodentia; Muridae)

et al. 2023

For many mammals, the tongue provides an important functional interface with the environment through roles including manipulating, ingesting, and mechanically processing food items. As such, the adaptations of the tongue reflect different physical properties of an animal’s diet. We sought to investigate whether adaptations of the tongue are apparent in two native Australian rodents that have divergent dietary niches: the semiaquatic and mixed feeding rakali (Hydromys chrysogaster) and the arid dwelling, herbivorous stick-nest rat (Leporillus conditor). Both species retained many lingual features typical of rodents. A notable difference was a large, annular pad surrounding the single circumvallate papilla in H. chrysogaster, suggesting an enhanced gustatory function, which would be consistent with adaptation to a semiaquatic, mixed diet. In contrast, L. conditor appeared to have reduced gustatory sensitivity and mechanical dexterity, consistent with crushing their preferred succulent plant forage and manipulating sticks for nest building. The descriptions provide a novel view of the evolution of soft tissues within Australian endemic rodents.
