| provenance of a new zealand brush-tailed rock-wallaby (petrogale penicillata) population determined by mitochondrial dna sequence analysis. | modern molecular genetic techniques provide a valuable means to address questions concerning the origins of naturalized populations. brush-tailed rock-wallabies (petrogale penicillata), of unknown provenance, were introduced to new zealand from australia in the early 1870s. while the introduced wallabies prospered in new zealand, their antecedents in australia experienced widespread local population extinctions as part of a drastic, widespread and ongoing decline. in this study, a polymerase cha ... | 2001 | 11742554 |
| estimating population size of endangered brush-tailed rock-wallaby (petrogale penicillata) colonies using faecal dna. | the brush-tailed rock-wallaby (petrogale penicillata) is an endangered species in southeastern australia and many of the remaining populations are declining. the steep rocky habitat and shy nature of the species make it difficult to obtain data on population parameters such as abundance and recruitment. faecal pellet counts from scat plots are commonly used to monitor population trends but these are imprecise and difficult to relate to absolute population size. we conducted a noninvasive genetic ... | 2006 | 16367832 |
| population structure of brush-tailed rock-wallaby (petrogale penicillata) colonies inferred from analysis of faecal dna. | genetic data obtained using faecal dna were used to elucidate the population structure of four brush-tailed rock-wallaby (petrogale penicillata) colonies located in wollemi national park, new south wales. the results suggested that the four sampled colonies are genetically differentiated and do not form a panmictic unit. based on assignment tests, approximately 5% of sampled individuals were inferred to be dispersers and both male and female migrants were detected. multilocus spatial autocorrela ... | 2006 | 16367833 |
