TLDR
Assessment of genetic diversity in D. lumholtzi suggests the species has relatively low levels of diversity which is uniformly distributed throughout the Atherton Tablelands; a pattern congruent with data from many othervertebrates endemic to the Australian Wet Tropics.Abstract:
Lumholtz’s tree-kangaroo (Dendrolagus lumholtzi) is one of two species of tree-kangaroo resident in the tropical rainforests of north-eastern Australia The species is confined to the Wet Tropics region, with its distribution centred on the Atherton Tablelands While D lumholtzi was exposed to periodic large-scale climatic fluctuations during the Quaternary that have effectively acted as natural fragmentation events, the species is currently under pressure from anthropogenic disturbance and habitat fragmentation This study aimed to assess the level of genetic diversity in D lumholtzi by examining hypervariable microsatellite loci and the control region of mitochondrial DNA (mtDNA) in 21 individuals from a single 20 ha forest fragment, and from a further 24 animals collected throughout the Atherton Tablelands Results suggest that D lumholtzi has relatively low levels of genetic diversity which is uniformly distributed throughout the Atherton Tablelands; a pattern congruent with data from many other vertebrates endemic to the Australian Wet Tropics It is suggested that Pleistocene climatic fluctuations, which resulted in large-scale rainforest contractions, have imposed an ancient population bottleneck on the ancestral D lumholtzi population The apparent over-riding influence of these natural, historical effects on the genetic structure of D lumholtzi populations, will complicate attempts to assess the genetic impact of current anthropogenic habitat loss and fragmentationread more

Gap Analysis of Environmental Research Needs in the Australian Wet Tropics
TL;DR: In this article, a review and consultation process with the aim of identifying end-user needs, research gaps and possible synergies is proposed to identify the areas of research where stakeholder interests overlap.

Conservation and health of Lumholtz's tree-kangaroo (Dendrolagus lumholtzi)
TL;DR: Health of Lumholtz’s tree-kangaroo appears to be impacted by the increase in humans and domestic animals in their range, and where increased information on health and population viability will improve conservation and management of the species is identified.

First record of quadruplets in the musky ratkangaroo Hypsiprymnodon moschatus.
TL;DR: It is shown that the birth of more than three young has not previously been observed in H. moschatus or any other macropodoid, even though all species possess four teats.

Molecular Evolutionary Genetics
TL;DR: Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.

Description and Power Analysis of Two Tests for Detecting Recent Population Bottlenecks from Allele Frequency Data
TL;DR: In this article, two statistical tests for detecting a heterozygosity excess are described, and the most useful markers for bottleneck detection are those evolving under the infinite allele model (IAM) and they provide guidelines for selecting sample sizes of individuals and loci.
