| cholangitis associated with species of progamotaenia (cestoda: anoplocephalidae) in the bile ducts of marsupials. | gross and histopathologic changes due to infection with progamotaenia festiva and p. effigia in the bile ducts of the marsupials, macropus rufus, m. giganteus, m. fuliginosus, lagorchestes conspicillatus, vombatus ursinus and lasiorhinus latifrons are described. the integrity of the bile duct mucosa was not impaired but varying degrees of hyperplasia and hypertrophy of mucosa and mucosal glands, inflammatory infiltration and fibrosis were found. portal fibrosis was the prominent reaction in lasi ... | 1978 | 691133 |
| digestive tract morphology and digestion in the wombats (marsupialia: vombatidae). | wombats consume grasses and sedges which are often highly fibrous. the morphology of the digestive tract and the sequence of digestion were studied in two species of wombats from contrasting habitats: vombatus ursinus from mesic habitats and lasiorhinus latifrons from xeric regions. studies were performed on wild wombats consuming their natural winter diets, and on captive wombats fed a high-fibre pelleted straw diet. vombatus had a shorter digestive tract (9.2 vs 12.5 times body length) of grea ... | 1992 | 1430423 |
| hindgut fermentation in the wombats: two marsupial grazers. | the wombats vombatus ursinus and lasiorhinus latifrons have a capacious proximal colon with only a vestigial caecum. the pattern of microbial fermentation in the hindgut of both species was studied in captive animals fed a pelleted straw diet and in wild wombats feeding on their natural winter diets. digesta ph was low in the stomach but near neutrality along the hindgut, indicating effective absorption and/or buffering of the colonic contents. initial proportions and production rates of short c ... | 1992 | 1430424 |
| adiaspiromycosis in south australian hairy-nosed wombats (lasiorhinus latifrons). | spherical organisms, with an average diameter of about 22 microns, were detected in the lungs of adult and pouched young hairy-nosed wombats (lasiorhinus latifrons). although infections of up to 640 x 10(3) organisms per cubic centimeter were detected, their presence produced only limited pathological change. in-vitro growth was obtained at 30 c but not at 37 c or 40 c. however, at the higher temperatures, typical chlamydospore spherules were produced by colonies initially grown at 30 c. this re ... | 1982 | 7201528 |
| the distribution and sizes of ganglion cells in the retinas of five australian marsupials. | maps of ganglion-cell distribution have been constructed from whole-mounted retinas of five australian marsupial species. the pademelon wallaby (thylogale billiardieri), the scrub wallaby or tammar (macropus eugenii), and the carnivorous tasmanian devil (sarcophilus harissi) have both a visual streak and an area centralis. the retina of the brown bandicoot (isoodon obesulus) also shows both these features but they are less prominent than in the former three species, whereas the burrow-dwelling, ... | 1981 | 7204673 |
| comparative erythrocyte metabolism in marsupials and monotremes. | concentrations of atp and dpg, activities of 10 enzymes and the glycolytic rates were measured in the erythrocytes of 11 species of marsupials and two species of monotremes. mean dpg concentrations were greater in the erythrocytes of marsupials than those of eutherian mammals. the opposite is true of atp. significant findings from the results of enzyme activities were: high activity of hexokinase (7.39 +/- 0.82 eu/g hb) in the short-beaked echidna, pyruvate kinase (37.49 +/- 1.0 eu/g) hb in brid ... | 1995 | 7599974 |
| comparative study of the antioxidant defence systems in the erythrocytes of australian marsupials and monotremes. | a comparison of the erythrocyte (rbc) antioxidant metabolites and enzymes in nine marsupial and two monotreme species was carried out. reduced glutathione (gsh) concentrations were comparable with those reported for other marsupial and eutherian species. an important finding was that the erythrocytes of the southern hairy nosed wombat regenerated gsh faster than the erythrocytes from its close relative, the common wombat. the activities of glutathione-s-transferase, nadh-methaemoglobin reductase ... | 1995 | 7599975 |

| follicular development in cryopreserved common wombat ovarian tissue xenografted to nude rats. | the northern hairy-nosed wombat (lasiorhinus krefftii) is a highly endangered marsupial species and every possible option for sustaining the species needs to be explored. one important approach may be the development of assisted reproductive technologies in the non-endangered common wombat (vombatus ursinus) and southern hairy-nosed wombat (lasiorhinus latifrons) for application in breeding the northern hairy-nosed wombat. in this study, it was examined whether cryopreserved wombat ovarian tissu ... | 2001 | 11182515 |
| faecal progesterone metabolites and behavioural observations for the non-invasive assessment of oestrous cycles in the common wombat (vombatus ursinus) and the southern hairy-nosed wombat (lasiorhinus latifrons). | wombats belong to australia's unique marsupial species. two of the three remaining species, the common wombat (vombatus ursinus) and the southern hairy-nosed wombat (lasiorhinus latifrons) are abundant. the third species, the northern hairy-nosed wombat (lasiorhinus krefftii) has only about 115 individuals left in the wild. this study aimed to gain further insight into the basic reproductive biology of wombat species and evaluate the value of faecal progesterone metabolites and behavioural patte ... | 2002 | 12137986 |
| antibodies to the ross river virus in captive marsupials in urban areas of eastern new south wales, australia. | serum samples collected from 224 tammar wallabies (macropus eugenii) in two captive populations in urban areas in eastern new south wales australia, between december 1999 and may 2004, were tested for antibodies to ross river virus (rrv). in one population in northwest sydney, 21 animals (11%) tested positive, and in another population in newcastle, new south wales, thirteen (33%) of the animals were positive. antibodies were detected in four of 11 wallaroos (macropus robustus) (36%) but not in ... | 2005 | 16244073 |
| effect of exogenous gonadotrophins on ovarian morphology and oocyte maturation in the southern hairy nosed wombat lasiohinus latifrons during the breeding season. | the effect of the exogenous administration of porcine follicle-stimulating hormone (pfsh) and pregnant mare serum gonadotrophin (pmsg) on ovarian follicular development and oocyte maturation in the southern hairy nosed wombat lasiorhinus latifrons was investigated. three experimental groups were administered pfsh at various doses and for different treatment lengths, followed by 25 mg porcine luteinising hormone (plh) 12 h after the last dose of pfsh. another group was given pmsg followed 72 h la ... | 2006 | 16737641 |
| ovarian follicular superstimulation and oocyte maturation in the anoestrous southern hairy-nosed wombat, lasiorhinus latifrons. | this study investigates the effect of three exogenous gonadotrophin regimens on ovarian follicular development in southern hairy-nosed wombats during the non-breeding season. females were given either porcine follicle stimulating hormone (pfsh; total of 200 mg at 12 h intervals over 7 (group 1), or 4 days (group 2)), or pregnant mares' serum gonadotrophin (pmsg; single dose of 150 i.u. (group 3)). in all treatment groups 25 mg of porcine luteinising hormone (plh) was used to trigger maturation; ... | 2007 | 16884866 |
| hematologic and serum biochemical reference values for free-ranging northern hairy-nosed wombats. | hematologic and serum biochemistry values were determined for 31 adult (21 male and 10 female) and four subadult male northern hairy-nosed wombats (lasiorhinus krefftii) from the only existing population in epping forest national park, australia. blood samples were obtained from free-ranging northern hairy-nosed wombats during trapping for population census and health and reproductive assessment in 1999. hematologic and biochemical values were compared between adult males and adult females, and ... | 2008 | 18263822 |
| molecular characterization of blastocystis isolates from zoo animals and their animal-keepers. | blastocystis is an enteric protist and one of the most frequently reported parasitic infections in humans and a variety of animal hosts. it has also been reported in numerous parasite surveys of animals in zoological gardens and in particular in non-human primate species. pcr-based methods capable of the direct detection of blastocystis in faeces were used to detect blastocystis from various hosts, including non-human primates, australian native fauna, elephants and giraffes, as well as their ke ... | 2010 | 20089360 |
| pharmacokinetics of moxidectin in the southern hairy-nosed wombat (lasiorhinus latifrons). | sarcoptic mange, caused by sarcoptes scabiei var. wombati, could be a significant threat to populations of southern hairy-nosed wombats (lasiorhinus latifrons; shnw) in australia. treatment is currently based on the off-label use of various parasiticidal drugs, with limited clinical efficacy trials. our primary aim was to determine the pharmacokinetic parameters of a macrocyclic lactone, moxidectin, to assist in the development of effective treatment protocols. pharmacokinetic parameters were de ... | 2011 | 21719829 |
| sarcoptic mange in wombats-a review and future research directions. | sarcoptic mange is caused by the mite sarcoptes scabiei and has recently been recognized as an emerging infectious disease of wildlife worldwide. the mite is one of the main causes of population decline in southern hairy-nosed (lasiorhinus latifrons) and bare-nosed wombats (vombatus ursinus). this review focuses on sarcoptes scabiei infestations in wombats and provides insights into why the disease may be so prevalent in wombats. current treatment practices and trials conducted in the field to r ... | 2017 | 29150905 |
| informative enzyme/probe combinations for the multilocus dna fingerprinting of marsupials. | dna fingerprinting has become an invaluable tool in the study of population genetics, paternity success, and individual identification; however, the species specificity of some methods has made the wide-range screening of many different species very time-consuming. in this study we describe the development and application of reliable and informative dna fingerprinting techniques in a range of marsupial species using three different restriction enzyme and two oligonucleotide probe combinations. s ... | 1997 | 9378146 |
| pouch young removal and return to oestrus in wild southern hairy-nosed wombats (lasiorhinus latifrons). | the southern hairy-nosed wombat (lasiorhinus latifrons) is a seasonal breeding, burrowing marsupial adapted to a semi-arid environment and the closest relative of the endangered northern hairy-nosed wombat (lasiorhinus krefftii). females typically give birth to one to two young every 3 years with young weaned at 360-400 days. this study examined the occurrence of polyoestry in a wild population of southern hairy-nosed wombats, and in particular the ability of this species to produce additional o ... | 2007 | 17023125 |
| determination of seasonality in southern hairy-nosed wombats (lasiorhinus latifrons) by analysis of fecal androgens. | little is known about the reproductive biology of australia's critically endangered northern hairy-nosed wombat (lasiorhinus krefftii), largely due to its cryptic nature and the difficulty in accessing the small remaining population of about 70 animals. using the noninvasive technique of fecal steroid analysis, we have examined the endocrinology of the more common yet closely related southern hairy-nosed wombat (lasiorhinus latifrons). the aims of this study were to 1) develop and validate fecal ... | 2000 | 10906060 |

| measurement of testosterone and cortisol metabolites and luteinising hormone in captive southern hairy-nosed wombat (lasiorhinus latifrons) urine. | this study reports the validation and use of enzyme immunoassays (eia) to measure changes in plasma and urinary luteinizing hormone, testosterone metabolites (utm) and cortisol metabolites (ucm) in captive southern hairy-nosed wombats (lasiorhinus latifrons). gnrh agonist and acth agonist challenges were conducted to validate urinary testosterone (male wombat only) and cortisol (male and female wombats) eias. following intra-muscular injection of 8-12μg buserelin (n=4 males), there was a signifi ... | 2017 | 28599837 |
| evidence of subdivisions on evolutionary timescales in a large, declining marsupial distributed across a phylogeographic barrier. | major prehistoric forces, such as the climatic shifts of the pleistocene, can remain visible in a species' population genetics. inference of refuges via genetic tools is useful for conservation management as it can identify populations whose preservation may help retain a species' adaptive potential. such investigation is needed for australia's southern hairy-nosed wombat (lasiorhinus latifrons), whose conservation status has recently deteriorated, and whose phylogeographic history during the pl ... | 2016 | 27732594 |
| effects of overnight captivity on antioxidant capacity and clinical chemistry of wild southern hairy-nosed wombats (lasiorhinus latifrons). | an animal's antioxidant capacity is measured by its ability to quench reactive oxygen species (ros). during everyday metabolism, antioxidants and ros are in equilibrium with one another. in times of stress, an animal produces more ros and therefore uses its antioxidant capacity more readily in order to maintain this equilibrium. when the production of ros exceeds the antioxidant capacity, an animal will experience extensive oxidative stress, which can ultimately affect that animal's health. duri ... | 2014 | 25314812 |
| non-invasive urine collection in the female southern hairy-nosed wombat (lasiorhinus latifrons) with the aid of classical conditioning. | we propose that regular urine samples can be used to monitor and characterize the reproductive cycle of the wombat, but this approach has never before been attempted in a marsupial. we conducted a three stage conditioning process for non-invasive urine collection in captive female wombats, which included (1) initial habituation and observation of urination patterns; (2) classical association of a stimulus with urination and (3) urine collection with the classically-conditioned stimulus. four of ... | 2015 | 25201777 |
| suspected pyrrolizidine alkaloid hepatotoxicosis in wild southern hairy-nosed wombats (lasiorhinus latifrons). | southern hairy-nosed wombats (lasiorhinus latifrons) inhabiting degraded habitat in south australia were recently identified with extensive hair loss and dermatitis and were in thin to emaciated body condition. pathological and clinicopathological investigations on affected juvenile wombats identified a toxic hepatopathy suggestive of plants containing pyrrolizidine alkaloids, accompanied by photosensitive dermatitis. hepatic disease was suspected in additional wombats on the basis of serum bioc ... | 2014 | 24708262 |
| the effect of group size on vigilance in a semi-solitary, fossorial marsupial (lasiorhinus latifrons). | prey species that congregate gain protection against predatory attacks and this advantage is often reflected by a reduction in vigilance behaviour by individuals in larger groups. comparatively few studies have investigated vigilance in solitary animals, but those that have, found that vigilance increases as group size increases because of the threat posed by conspecifics and/or competition for resources. the southern hairy-nosed wombat (lasiorhinus latifrons) is a large fossorial, nocturnal mar ... | 2013 | 24140418 |
| effects and treatment of sarcoptic mange in southern hairy-nosed wombats (lasiorhinus latifrons). | we examined the clinical and cellular effects of sarcoptic mange on southern hairy-nosed wombats (shnw, lasiorhinus latifrons) and the effectiveness of a single dose of ivermectin as a treatment for captive and wild animals. wambats were caught at three sites in south australia between april and august 2005 and blood and skin samples were collected. hematology, biochemistry, and protein electrophoresis reference intervals were determined for healthy and diseased shnw. diseased shnw had significa ... | 2013 | 23568906 |
| the seminiferous epithelial cycle and microanatomy of the koala (phascolarctos cinereus) and southern hairy-nosed wombat (lasiorhinus latifrons) testis. | the koala (phascolarctos cinereus) and southern hairy-nosed wombat (lasiorhinus latifrons) are iconic australian fauna that share a close phylogenetic relationship but there are currently no comparative studies of the seminiferous epithelial cell or testicular microanatomy of either species. koala and wombat spermatozoa are unusual for marsupials as they possess a curved stream-lined head and lateral neck insertion that superficially is similar to murid spermatozoa; the koala also contains serto ... | 2013 | 23278248 |
| auditory laterality in a nocturnal, fossorial marsupial (lasiorhinus latifrons) in response to bilateral stimuli. | behavioural lateralisation is evident across most animal taxa, although few marsupial and no fossorial species have been studied. twelve wombats (lasiorhinus latifrons) were bilaterally presented with eight sounds from different contexts (threat, neutral, food) to test for auditory laterality. head turns were recorded prior to and immediately following sound presentation. behaviour was recorded for 150 seconds after presentation. although sound differentiation was evident by the amount of explor ... | 2013 | 23231543 |
| non-invasive methods of oestrus detection in captive southern hairy-nosed wombats (lasiorhinus latifrons). | in order to develop a reliable method of oestrus detection in captive southern hairy-nosed (shn) wombats, the reproductive behaviour of four groups of adult animals (1 male:2 female) was monitored using video surveillance and activity using movement-sensitive radio transmitters for a period of 12 months. during this time faecal samples were collected every 3 days and subsequently analysed for progesterone and oestradiol-17beta metabolites. in an attempt to induce and characterise oestrus-specifi ... | 2010 | 20163924 |
| monitoring male southern hairy-nosed wombat (lasiorhinus latifrons) reproductive function and seasonality in a captive population. | this study reports on the development and application of techniques used to assess the reproductive status of captive male southern hairy-nosed wombats (n=4) at rockhampton zoo. initially, a gnrh agonist was used to establish a method for determining a reliable index of plasma and faecal testosterone secretion. intra-muscular injection of buserelin (4 microg) resulted in an increase (p<0.05) in plasma and faecal testosterone concentration 90 min and 3 days after administration, respectively. sea ... | 2010 | 19892498 |
| evidence for habitat fragmentation altering within-population processes in wombats. | habitat fragmentation and associated reduced dispersal of wildlife can lead to an accumulation of related individuals in fragments. the altered kin interactions and amplified chance of inbred matings has profound implications for mating and social systems, and ultimately population persistence. nonetheless, within-fragment population processes are rarely studied. with this aim, we examined relatedness structure in two candidate isolated populations (kulpara and scrubby peak) of southern hairy-no ... | 2008 | 18386311 |
| female dispersal and male kinship-based association in southern hairy-nosed wombats (lasiorhinus latifrons). | generalizations about sociobiology require investigations of species with diverse ecological roles and phylogenetic affiliations. the southern hairy-nosed wombat (lasiorhinus latifrons) is valuable here, in that it is a marsupial of semi-arid habitat, and one of the largest burrowing herbivores (commonly attaining 26 kg). its sociobiology is poorly understood because the species is nocturnal, shy, and difficult to observe or capture nondisruptively. to investigate aspects of the species' sociobi ... | 2008 | 18302694 |
| does soil type drive social organization in southern hairy-nosed wombats? | spatiotemporal distributions of key resources are hypothesized to underpin sociobiological patterns. burrow availability and quality is of paramount importance to fossorial animals. the southern hairy-nosed wombat (lasiorhinus latifrons) burrows in both hard and friable soils. theoretical and empirical studies suggest that the harder substrate should promote closer geographical clustering of burrows than in softer soils. clustered burrows are expected to be associated with larger group sizes. if ... | 2007 | 17181731 |
| oestrous cycle of captive southern hairy-nosed wombats (lasiorhinus latifrons) in south australia, australia. | there is limited information available on the oestrous cycle of female southern hairy-nosed wombats (lasiorhinus latifrons). this is mainly due to an extremely poor breeding success in captivity and the difficulty in routine recapturing of these cryptic, semi-fossorial animals in the wild. the aim of this study was to characterise the oestrous cycle of this species by monitoring peripheral plasma concentrations of progesterone and oestradiol, assessing changes in vaginal cytology, pouch conditio ... | 2006 | 16289971 |
| ventilation and metabolism in a large semifossorial marsupial: the effect of graded hypoxia and hypercapnia. | metabolic and ventilatory variables were measured in a large semifossorial marsupial, the hairy-nosed wombat (lasiorhinus latifrons, 21.9 kg). in normoxia, the rate of oxygen consumption was 63% of that predicted for a similar-sized marsupial, and the level of ventilation (v(e)) was such that the convective requirement (v(e)/vo2) was similar to other mammals. exposure to hypercapnia (5% co(2)) evoked a hyperventilatory response (3.55 x normoxia) that was no different to that observed for epigeal ... | 2013 | 11880980 |
| comparative chromosome painting between marsupial orders: relationships with a 2n = 14 ancestral marsupial karyotype. | a 2n = 14 karyotype is shared by some species in each of the marsupial orders in australian and american superfamilies, suggesting that the ancestral marsupial chromosome complement was 2n = 14. we have used chromosome painting between distantly related marsupial species to discover whether genome arrangements in 2n = 14 species in two australian orders support this hypothesis. cross-species chromosome painting was used to investigate chromosome rearrangements between a macropodid species macrop ... | 1999 | 10598566 |
| immunocytochemical identification of cells containing insulin, glucagon, somatostatin, and pancreatic polypeptide in islets of langerhans of the wombat pancreas with electron microscopy. | the endocrine pancreas of the southern hairy-nosed wombat (lasiorhinus latifrons) was investigated by means of electron-microscope immunocytochemistry using the protein a--gold technique on london resin (lr) white-embedded tissue. the primary antibodies used were raised against insulin, glucagon, somatostatin and pancreatic polypeptide. the morphology of the secretory granules differed in the four cell types. the insulin cells are pleiomorphic, and the secretory granules composed of an electron- ... | 1997 | 9359033 |
| histology and histochemistry of the accessory reproductive glands in the male hairy-nosed wombat (lasiorhinus latifrons). | the accessory male reproductive glands of the hairy-nosed wombat, lasiorhinus latifrons, are a prostate and three pairs of cowper's glands. component units of all are branched tubular structures of varying epithelial makeup and secretory content. the prostate has the carrotlike shape and three consecutive regions commonly found in marsupials. the regions differ in their tubular histology and histochemistry: all contain secretory globules in glandular lumina. cowper's glands a and b are histologi ... | 1981 | 6169693 |
| haematology and clinical chemistry of hairy-nosed wombats (lasiorhinus latifrons). | the report summarises an investigation into the health of wombats (lasiorhinus latifrons) in the field during the breeding season of a drought year. health was assessed by morphometry, haematology and clinical chemistry and the findings were compared with those obtained for apparently healthy captaive wombats. the erythrocyte count was lower and the erythrocyte size greater in free-ranging wombats than in captaive wombats. plasma values for potassium, urea, lactate dehydrogenase and aspartate tr ... | 1980 | 7431528 |

| genetic variation within the genus macropostrongyloides (nematoda: strongyloidea) from australian macropodid and vombatid marsupials. | the genetic variation and taxonomic status of the four morphologically-defined species of macropostrongyloides in australian macropodid and vombatid marsupials were examined using sequence data of the its+ region (=first and second internal transcribed spacers, and the 5.8s rrna gene) of the nuclear ribosomal dna. the results of the phylogenetic analyses revealed that ma. baylisi was a species complex consisting of four genetically distinct groups, some of which are host-specific. in addition, m ... | 2019 | 31397236 |
| dual-locus dna metabarcoding reveals southern hairy-nosed wombats (lasiorhinus latifrons owen) have a summer diet dominated by toxic invasive plants. | habitat degradation and summer droughts severely restrict feeding options for the endangered southern hairy-nosed wombat (shnw; lasiorhinus latifrons). we reconstructed shnw summer diets by dna metabarcoding from feces. we initially validated rbcl and ndhj diet reconstructions using autopsied and captive animals. subsequent diet reconstructions of wild wombats broadly reflected vegetative ground cover, implying local rather than long-range foraging. diets were all dominated by alien invasives. c ... | 2020 | 32142513 |
| serum biochemistry of free-ranging southern hairy-nosed wombats (lasiorhinus latifrons). | listed as near-threatened by the international union for conservation of nature (iucn), the southern hairy-nosed wombat (shnw, lasiorhinus latifrons) faces threats such as drought, habitat degradation and loss, disease, and persecution because of competition with agriculture. to assist with evaluation of wombat health, this study reports serum biochemical reference intervals (ris) for wild-caught shnw from south australia established from 126 apparently healthy shnw using a beckman coulter au480 ... | 2020 | 31926526 |
| ovary of the southern hairy-nosed wombat (lasiorhinus latifrons): its divergent structural organisation. | the organisation of the ovarian interstitial tissue in the southern hairy-nosed wombat lasiorhinus latifrons was investigated. unlike in most other marsupials, the outer cortical region of the ovary contains abundant luteinised interstitial tissue that largely occurs in discrete lobules, many of which contain a localised area of non-cellular, highly eosinophilic and periodic acid-schiff-positive material. the findings suggest that the latter arises from the zona pellucida that surrounded the ooc ... | 2019 | 31030725 |
| a comparison between video and still imagery as a methodology to determine southern hairy-nosed wombat (lasiorhinus latifrons) burrow occupancy rates. | broad-scale abundance estimates of the southern hairy-nosed wombat population use a proxy measure based on counting the number of active burrows, which is multiplied by an index of 'wombats/active burrow'. however, the extant indices were calculated in the 1980s, prior to the use of calicivirus to control rabbits, and used invasive monitoring methods which may have affected the results. we hypothesise that the use of video might provide a logistically simple, non-invasive means of calculating up ... | 2018 | 30360470 |
| reproductive biology of captive female southern hairy-nosed wombats (lasiorhinus latifrons). part 2: oestrous behaviour. | the poor captive breeding success of southern hairy-nosed wombats (shnws; lasiorhinus latifrons) has been attributed to the difficulty in accurately characterising oestrous behaviour and their relationship to circulating reproductive hormones. over two wombat breeding seasons, the use of infrared cameras for 24-h remote behavioural monitoring and the analysis of urine samples collected from seven captive females, were investigated to determine the relationship between behaviour and changes in ur ... | 2018 | 29742384 |
| reproductive biology of captive southern hairy-nosed wombats (lasiorhinus latifrons). part 1: oestrous cycle characterisation. | southern hairy-nosed wombats (shnws: lasiorhinus latifrons) do not breed well in captivity. to better understand their reproduction, daily urine samples were collected from nine captive females and analysed for volume (ml), specific gravity and a qualitative index of the number of epithelial cells, then stored at -20°c until samples could be analysed for progesterone metabolites (p4m). the mean oestrous cycle length was 35.1±2.4 days; however, individual cycle length ranged from 23 to 47 days. t ... | 2018 | 29742383 |
