| revision of the progamotaenia zschokkei (janicki, 1905) complex (cestoda: anoplocephalidae), with the description of six new species. | a review of cestodes currently attributed to progamotaenia zschokkei (janicki, 1905) (cestoda: anoplocephalidae) suggests that six additional species are present: pr. tenuis n. sp. found in thylogale stigmatica (gould) and t. thetis (lesson), pr. lomatosoma n. sp.from macropus agilis (gould), pr. petrogale n. sp. from petrogale spp. and macropus dorsalis(grey), pr. fimbriata n.s p. from lagorchestes conspicillatus gould and l. hirsutus gould, pr. obesa n. sp. from onychogalea fraenata (gould) an ... | 2007 | 17323116 |
| microchips for macropods: first use of a microchip-automated door by a bridled nailtail wallaby (onychogalea fraenata). | commercially available microchip-automated devices for companion animals also have potential application with captive wildlife. to explore this potential, a captive bridled nailtail wallaby was trained to use a sureflap microchip pet door. throughout the 62 day study the wallaby's interactions with the door increased in frequency and intensity, culminating in the repeated use of the microchip-automated door. this was the first record of any captive macropod being trained to use a microchip-autom ... | 2018 | 29923213 |
| effects of body size and home range on access to mates and paternity in male bridled nailtail wallabies. | the bridled nailtail wallaby, onychogalea fraenata, is a relatively small, solitary and sexually size dimorphic macropod. we studied the mating system of free-ranging wallabies over 3 years, using microsatellite analysis of paternity, radiotelemetry and behavioural observations. both sexes were promiscuous, and general reproductive behaviour was similar to that of larger, better-known macropods. home range size influenced the number of associations with oestrous females, and was a significant co ... | 1999 | 10413548 |
| optimal adaptive management for the translocation of a threatened species. | active adaptive management (aam) is an approach to wildlife management that acknowledges our imperfect understanding of natural systems and allows for some resolution of our uncertainty. such learning may be characterized by risky strategies in the short term. experimentation is only considered acceptable if it is expected to be repaid by increased returns in the long term, generated by an improved understanding of the system. by setting aam problems within a decision theory framework, we can fi ... | 2009 | 19323207 |
| scrub-itch mite infestation in the endangered bridled nailtail wallaby. | skin lesions on the ears and inguinal and axillary regions of a number of adult animals within a captive population of the endangered bridled nailtail wallaby (onychogalea fraenata) were associated with the trombiculid mite, eutrombicula hirsti. the local inflammatory response of these australian marsupials is described. | 2009 | 19673851 |
| mass capture and anesthesia of australian bridled nailtail wallabies (onychogalea fraenata) with the use of medetomidine and ketamine. | we anesthetized 301 bridled nailtail wallabies (onychogalea fraenata), captured within scotia sanctuary, new south wales, australia over four nights in october 2009 to perform health assessments before their release into a predator-proof exclosure. we tested two anesthetic dose-rate combinations, protocol 1 (0.08 mg/kg medetomidine-4.5 mg/kg ketamine), and protocol 2 (0.1 mg/kg medetomidine-5 mg/kg ketamine), each given intramuscularly. median time from injection to recumbency for protocol 1 was ... | 2014 | 25105815 |
| molecular identification and expression of lyn tyrosine kinase isoforms in marsupials. | lyn is a tyrosine kinase molecule required for modulation of signalling cascades in cell populations including b lymphocytes of the mammalian immune system. we have characterised the coding domain of the marsupial lyn gene of two macropod marsupials; the tammar wallaby (macropus eugenii) and the bridled nailtail wallaby (onychogalea fraenata) and show the co-expression of two lyn isoforms in cells and tissues of these and three other marsupials (brush-tail possum, trichosurus vulpecula; american ... | 2013 | 23522727 |
| isoforms of the cd79 signal transduction component of the macropod b-cell receptor. | b cell responses and their concomitant signal transduction pathways are not well understood in marsupial mammals, despite the availability of gene expression data for key immunoglobulin genes and for elements of the cd79a/cd79b heterodimer signalling complex for two model marsupials. broader studies of factors that influence b cell responses are still hampered by a lack of species-specific reagents and there are few reports of other factors that influence gene expression such as the potential fo ... | 2014 | 25064685 |
| the common gamma chain cytokine interleukin-21 is expressed by activated lymphocytes from two macropod marsupials, macropus eugenii and onychogalea fraenata. | in mammals, interleukin-21 is a member of the common gamma chain cytokine family that also includes il-2, il-4, il-7, il-9 and il-15. il-21 has pleiotropic effects on both myeloid and lymphoid immune cells and as a consequence, the biological actions of il-21 are broad: regulating both innate and adaptive immune responses and playing a pivotal role in antiviral, inflammatory and antitumour cellular responses. while il-21 genes have been characterized in mammals, birds, fish and amphibians, there ... | 2016 | 27306193 |
| genetic variation in the mitochondrial cytochrome c oxidase subunit 1 within three species of progamotaenia (cestoda: anoplocephalidae) from macropodid marsupials. | sequence variation within 3 morphologically defined species of the anoplocephalid cestode genus progamotaenia (p. ewersi, p. macropodis and p. zschokkei) was investigated using the cytochrome c oxidase subunit 1 gene. the magnitude of genetic variation detected within each morphospecies suggests that, in each instance, several cryptic species are present. within p. ewersi, 5 genetically distict groups of cestodes were detected, 1 shared by macropus robustus and m. parryi in queensland, 1 in m. a ... | 2005 | 15700763 |
