Distortion of allele frequency distributions provides a test for recent population bottlenecks.
It is demonstrated that population bottlenecks cause a characteristic mode-shift distortion in the distribution of allele frequencies at selectively neutral loci, and a qualitative graphical method is illustrated and evaluated for detecting a bottleneck-induced distortion of allele frequency distributions.
Usefulness of molecular markers for detecting population bottlenecks via monitoring genetic change
The variance test was most powerful; it provided an 85% probability of detecting a bottleneck of size Ne = 10 when monitoring five microsatellite loci and sampling 30 individuals both before and one generation after the bottleneck.

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.
Genetic variation of microsatellite loci in a bottlenecked species: the northern hairy‐nosed wombat Lasiorhinus krefftii
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.
Population structure in an inshore cetacean revealed by microsatellite and mtDNA analysis: Bottlenose dolphins (Tursiops sp.) in Shark Bay, Western Australia
The results indicate that dispersal in female dolphins in Shark Bay is more restricted than that of males, and analysis of genetic differentiation between sampling localities showed a pattern of isolation-by-distance.

Using mitochondrial DNA analyses, it is shown that sponging shows an almost exclusive vertical social transmission within a single matriline from mother to female offspring, adding a new dimension to charting cultural phenomena among animals.
A BIOPSY SYSTEM FOR SMALL CETACEANS: DARTING SUCCESS AND WOUND HEALING IN TURSIOPS SPP.
Overall sampling success for obtaining biopsy samples when an animal was struck ranged from 96.6% to 100% in the four populations, however, hit rate varied for the four different populations.
Characterization of microsatellite loci in Tursiops aduncus
The cloning and characterization of five highly polymorphic microsatellite loci cloned from aduncus dolphins from Western Australia are described, and it is found that these markers are likely to be useful in a number of cetacean population studies.
Invasive species can't cover their tracks: using microsatellites to assist management of starling (Sturnus vulgaris) populations in Western Australia

It is shown that genetic techniques can provide information regarding the source and pathway of the invasion, and the degree of connectivity with other populations can greatly benefit management strategies, even when applied to highly vagile species over continental scales.
Detecting bottlenecks using BOTTLENECK 1.2.02 in wild populations: the importance of the microsatellite structure

The efficiency with which this software detects bottlenecks in two koala populations of known history is tested, and the sign test performed well, suggesting this model could be the more realistic for marsupial microsatellites than other mutation models.
