Genotyping of koalas at CA‐repeat microsatellite loci has revealed significant differences in the levels of allelic diversity (A) and expected heterozygosity (HE) between populations from north‐eastern and south‐eastern Australia. In the 10 populations studied, allelic diversity ranged from 8.0 in the Nowendoc population to 1.7 in the Kangaroo Is. population, and values of HE ranged from 0.831 in the Nowendoc population to 0.331 in the Kangaroo Is. population. Data from pooled populations… 
Population genetics of the koala (Phascolarctos cinereus) in north-eastern New South Wales and south-eastern Queensland
TLDR
It is suggested that koala populations in north-eastern New South Wales and south-e eastern Queensland are experiencing contemporary impediments to gene flow, and the importance of maintaining habitat connectivity across this region is highlighted.
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.
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.
Genetic Analysis reveals a distinct and highly diverse Koala (Phascolarctos cinereus) population in South Gippsland, Victoria, Australia
TLDR
It is illustrated that historic anthropogenic impacts have had little effect on reducing the genetic diversity of a population in the South Gippsland region, and it is suggested that the SouthGippslands koalas require an alternative conservation management program.
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.
Molecular population genetic analysis of the spectacled bear (Tremarctos ornatus) in the northern Andean area.
TLDR
The low heterozygosity and the population fragmentation could be explained by ancient events related to the bear colonization, with the arrival of humans beings in the Americas, and/or with the glacial maximum, 16.000-30.000 years ago.
Genetic diversity in natural and introduced island populations of koalas in Queensland
TLDR
The genetic diversity of the naturally occurring population of koalas on North Stradbroke Island in south-east Queensland is compared with other island populations including the introduced group on St Bees Island in central Queensland, indicating that it is most unlikely that these populations were established by a sole secondary introduction.
Genetic diversity and population structure of Tasmanian devils, the largest marsupial carnivore
TLDR
Genetic diversity and population structure were investigated across the core range of Tasmanian devils, a wide‐ranging marsupial carnivore restricted to the island of Tasmania, implying limited dispersal of devils between the well‐connected, eastern populations and a smaller northwestern population.
Microsatellite variation and population structure in a declining Australian Hylid Litoria aurea
TLDR
It is concluded that maintaining areas of continuous habitat is critical to the conservation of the species and argued that population recovery and/or persistence in all areas sampled is possible if appropriate protection and management are afforded.
Genetic structure and diversity of the koala population in South Gippsland, Victoria: a remnant population of high conservation significance
TLDR
Compared to other Victorian koala populations, greater genetic diversity found in South Gippsland koalas, may provide this population with a greater chance of survival in the face of future environmental pressures.

Low genetic diversity and inbreeding depression in Queensland koalas
TLDR
The hypothesis that koalas have a history of small population size, resulting in reduced susceptibility to inbreeding depression is suggested, because of the limited data it would be premature to conclude thatKoalas are relatively resistant to the effects of inbreeding.
VNTR loci reveal differentiation between and structure within populations of the eastern barred bandicoot Perameles gunnii
TLDR
It is concluded that VNTR markers can be of benefit for use in studies of population differentiation and for conservation management.
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.
Influence of Fragmentation and Bottlenecks on Genetic Divergence of Wild Turkey Populations
TLDR
Fragmented distributions and population bottlenecks due to human activities appear to have increased genetic differentiation among populations of wild turkeys, which agrees with theoretical predictions concerning the effects of isolation and bottlenekks on the genetic structure of field populations.

Genetic basis for species vulnerability in the cheetah.
TLDR
The extreme genetic monomorphism, especially at the major histocompatibility complex, and the apparent hypersensitivity of the cheetah to a viral pathogen may be related, provide a biological basis for understanding the adaptive significance of abundant genetic variation in outbred mammalian species.
A molecular analysis of relationships and biogeography within a species complex of Holarctic fish (genus Osmerus)
TLDR
P Phenetic and parsimony analyses of the sequence divergence estimates and of sequence polymorphisms suggested that the north Pacific/Arctic form and the northwestern Atlantic form shared a common ancestor more recently than either has with the north‐eastern Atlantic form, thus supporting the hypothesis that the species complex has arisen from two independent Pacific‐Atlantic divergences probably beginning during the mid‐Pliocene.
Paternity exclusion in koalas using hypervariable microsatellites.
TLDR
It is demonstrated that microsatellite loci are ideal genetic markers for paternity exclusion and pedigree analysis of koalas, which have shown little genetic variation using most other methods.
