The koala, Phascolarctos cinereus, is a geographically widespread species endemic to Australia, with three currently recognized subspecies: P.c. adustus, P.c. cinereus, and P.c. victor. Intraspecific variation in the mitochondrial DNA (mtDNA) control region was examined in over 200 animals from 16 representative populations throughout the species’ range. Eighteen different haplotypes were defined in the ≈ 860 bp mtDNA control region, as determined by heteroduplex analysis/temperature gradient… Expand
Genetic diversity and gene flow among southeastern Queensland koalas (Phascolarctos cinereus)
TLDR
The limited distribution of the central phylogenetic haplotype suggested the possibility of historical population bottlenecks north of the Gold Coast, while the presence of two highly divergent haplotypes at the Moreton site may indicate the occurrence of one or more undocumented translocation events into this area. Expand
Historically low mitochondrial DNA diversity in koalas (Phascolarctos cinereus)
TLDR
Low genetic diversity of the hypervariable region of mitochondrial DNA in koala museum specimens collected in the 19th and 20th centuries may not indicate recent inbreeding or founder events but may reflect an older historical pattern for koalas. Expand
Phylogeography of the Koala, (Phascolarctos cinereus), and Harmonising Data to Inform Conservation
TLDR
A holistic approach is critical to ensuring management is effective and small scale local population studies can be integrated into a wider species context, suggesting habitat fragmentation may have restricted female-mediated gene flow. Expand
Conservation genetics of the black rhinoceros (Diceros bicornis)
TLDR
Phylogenetic relationships between mtDNA haplotypes analyzed using the neighbor joining method reveal that for the small sample available, D. b. Expand
Phylogeographic patterns and conservation units of a vulnerable species, Cabot’s tragopan (Tragopan caboti), endemic to southeast China
TLDR
It is suggested that two management units (MUs) should be defined in T. caboti for conservation based on the results of genetic analyses combined with geographic isolation and distinct population history. Expand
Genome-wide SNP loci reveal novel insights into koala (Phascolarctos cinereus) population variability across its range
TLDR
This is the first use of genome-wide markers to assess population differentiation at a broad-scale in the koala and the first time that sex-linked SNPs have been identified in this species. Expand
Mitochondrial phylogeography of the Eurasian beaver Castor fiber L.
TLDR
The low level of sequence divergence of the entire cytochrome b gene among six individuals representing six subspecies suggests differentiation during the last glacial period and existence of multiple glacial refugia. Expand
Phylogeography and population structure of an ecotonal marsupial, Bettongia tropica, determined using mtDNA and microsatellites
TLDR
It is found that it may be more difficult to detect molecular signatures for recent bottlenecks under conditions of very low migration rates than for isolated populations and, conversely, that ‘false’ bottleneck signatures may be observed at higher migration rates. Expand
High effective inbreeding coefficients correlate with morphological abnormalities in populations of South Australian koalas (Phascolarctos cinereus)
TLDR
Low levels of allelic diversity and differentiation at nuclear loci between populations paralleled known recent population history, except for the close relationship between Mt Lofty Ranges and French Is, are of concern when evaluating the long-term conservation and viability of the South Australian koala populations, which may benefit from genetic augmentation in the future.

Koalas (Phascolarctos cinereus) From Queensland Are Genetically Distinct From 2 Populations in Victoria.
TLDR
Queensland koalas displayed high mitochondrial haplotype diversity and nucleotide diversity, indicating along with the microsatellite data that North American zoos have maintained high levels of genetic diversity among their Queensland Koalas, thereby suggesting that geographic structuring should be considered in the conservation management of koala.

Conservation genetics of the koala (Phascolarctos cinereus): low mitochondrial DNA variation amongst southern Australian populations.
TLDR
The mtDNA data are consistent with the interpretation that the koala translocation programme has homogenized gene frequencies amongst those populations involved, and South Gippsland is not recorded as having received translocated koalas directly, and has significantly different mtDNA-RFLP haplotype frequencies from all other populations examined.

xtreme population structuring in the threatened ghost bat, Macroderma gigas: evidence from mitochondrial DNA
TLDR
The depth of the genetic structuring suggests that the isolation of extant populations preceded the historical range contraction of the ghost bat, and it is suggested that this extreme genetic subdivision is a consequence of long-term female philopatry. Expand

The genetic population structure of a large, wide‐ranging marsupial, the red kangaroo (Macropus rufus) was assessed using sequence and haplotype frequency data of mitochondrial DNA (mtDNA) fromExpand
Low genetic variability of the koala Phascolarctos cinereus in south‐eastern Australia following a severe population bottleneck
TLDR
The significantly lower levels of variation between south‐eastern Australian populations suggests that human intervention has had a severe effect on levels of genetic diversity in this region, and this may have long‐term genetic consequences. Expand
Phylogeographic Subspecies Recognition in Leopards (Panthera pardus): Molecular Genetic Variation
TLDR
The incorporation of precise definitions for taxonomic units into wildlife legislation has necessitated the reevaluation of the taxonomy of endangered and threatened species, and it is recommended that subspecific leopard taxonomy be revised to comprise eight subspecies. Expand
Genetic variation of microsatellite loci in a bottlenecked species: the northern hairy‐nosed wombat Lasiorhinus krefftii
TLDR
The results show that appreciable levels of variation still exist in the Epping Forest colony although it has only 41% of the heterozygosity shown in a population of a closely‐related species, which is consistent with an extremely small effective population size throughout its 120‐year decline. Expand
Genetic population structure of the Greater Bilby Macrotis lagotis, a marsupial in decline
TLDR
The available evidence suggests that the bilby should be considered as a single Evolutionarily Significant Unit consisting of multiple Management Units because of the extent of current and historical subdivision across the species range. Expand
Mitochondrial DNA analysis implying extensive hybridization of the endangered red wolf Canis rufus
TLDR
Phylogenetic analysis indicates that red wolves have either a grey wolf or coyote mtDNA genotype, demonstrating hybridization among these species, and does not argue against the continued protection of the red wolf. Expand
Phylogeography, population structure and dispersal patterns of the beluga whale Delphinapterus leucas in the western Nearctic revealed by mitochondrial DNA
TLDR
The patterns of mtDNA variation in beluga whales indicated that the summering concentrations are demographically, if not phyletically distinct, while asymmetries in dispersal may be associated with the type of mating system. Expand
Population structure of the yellow‐footed rock‐wallaby Petrogale xanthopus (Gray, 1854) inferred from mtDNA sequences and microsatellite loci
TLDR
The genetic results suggest that dispersal between colonies is limited, consistent with an ecological study of dispersal at one of the sites, and suggest that management of yellow‐footed rock‐wallabies should treat each colony as an independent unit and that conservation of the Queensland and South Australian populations as separate entities is warranted.
