| chromosomal rearrangements in rock wallabies, petrogale (marsupialia: macropodidae). ix. further g-banding studies of the petrogale lateralis complex: p. lateralis pearsoni, the west kimberley race, and a population heterozygous for a centric fusion. | g-banded metaphase preparations from cultured fibroblasts were used to examine the karyotypes of petrogale lateralis pearsoni and the west kimberley (wk) race of p. lateralis. petrogale lateralis pearsoni was found to retain the ancestral 2n = 22 petrogale karyotype, while the wk race (2n = 20) was found to be characterized by a 9-10 centric fusion. this taxon had been reported to have an 8-10 fusion. karyotypic analysis was also used to identify petrogale populations in the erskine range, weste ... | 1997 | 9061916 |
| comparative water metabolism of barrow island macropodid marsupials: hormonal versus behavioural-dependent mechanisms of body water conservation. | seasonal variations in rates of water turnover were measured over a 7-year period in four species of macropodid marsupials (lagorchestes conspicillatus, bettongia lesueur, petrogale lateralis and macropus robustus isabellinus), on barrow island off the arid pilbara coast of western australia. these ranged from over 100 ml kg(-0.82) d(-1) in wet seasons to as low as 28.2 ml kg(-0.82) d(-1) in dry seasons in the spectacled hare wallaby, l. conspicillatus. plasma osmolality increased significantly ... | 2008 | 17720162 |
| a role for selective contraception of individuals in conservation management programs. | contraception has an established role to play in managing overabundant populations and preventing undesirable breeding in zoos. we propose that it can also be used strategically and selectively in conservation management programs to increase the genetic and behavioural quality of the animals. in captive breeding programs, it is becoming increasingly important to maximise the retention of genetic diversity by managing the reproductive contribution of each individual, and preventing genetically su ... | 2017 | 29080297 |
| source population of dispersing rock-wallabies (petrogale lateralis) identified by assignment tests on multilocus genotypic data. | the ability to confidently identify or exclude a population as the source of an individual has numerous powerful applications in molecular ecology. several alternative assignment methods have recently been developed and are yet to be fully evaluated with empirical data. in this study we tested the efficacy of different assignment methods by using a translocated rock-wallaby (petrogale lateralis) population, of known provenance. specimens from the translocated population (n = 43), its known sourc ... | 2001 | 11903898 |
| haematology and biochemistry of warru (petrogale lateralis macdonnell ranges race) in captivity and the wild. | use haematology, biochemistry and protein electrophoresis analyses to establish reference values for, and describe the health status of, wild and captive colonies of critically endangered warru (black-footed rock-wallaby: petrogale lateralis macdonnell ranges race). | 2012 | 22928680 |
| finding the balance: fertility control for the management of fragmented populations of a threatened rock-wallaby species. | populations of australian marsupials can become overabundant, resulting in detrimental impacts on the environment. for example, the threatened black-flanked rock-wallaby ( petrogale lateralis lateralis ) has previously been perceived as overabundant and thus 'unwanted' when they graze crops and cause habitat degradation. hormonally-induced fertility control has been increasingly used to manage population size in other marsupials where alternative management options are not viable. we tested whet ... | 2015 | 26694471 |
| eimeria species in the pearson island rock wallaby, petrogale lateralis pearsoni. | four species of previously described eimeria were identified from oocysts present in the faeces of pearson island rock wallabies, petrogale lateralis pearsoni from pearson island, south australia. eimeria petrogale and eimeria sharmani have been reported in p. lateralis; however, the presence of eimeria godmani and eimeria inornata expands the suite of eimerian species known in rock wallabies of the "lateralis" complex. these observations indicate that the host distribution of eimeria species in ... | 1998 | 9925269 |
