| ultrastructure and motility of spermatozoa in macropodid and potoroidid marsupials. | in order to gain some understanding of the significance of the morphological features of spermatozoa within the macropodoidea, the motility of spermatozoa from two macropodids (petrogale xanthopus and dendrolagus matschiei) and the motility, number and distribution of spermatozoa from three potoroidids (aepyprymnus rufescens, bettongia penicillata and potorous tridactylus) were examined. sperm were collected by electro-ejaculation or from the cauda epididymides. epididymides from the potoroidids ... | 1995 | 8848581 |
| hypoaldosteronism in a matschie's tree kangaroo (dendrolagus matschiei). | a 20-yr-old female matschie's tree kangaroo (dendrolagus matschiei) was diagnosed with hypoaldosteronism, a rare condition in which the body fails to produce normal amounts of the mineralocorticoid aldosterone. aldosterone plays a key role in body salt homeostasis, increasing sodium reabsorption and promoting excretion of potassium. hypoaldosteronism resulted in decreased appetite, lethargy, and weight loss in conjunction with hyponatremia, hyperkalemia, and hypercalcemia in this tree kangaroo. ... | 2016 | 27468039 |
| comparative mtdna analyses of three sympatric macropodids from a conservation area on the huon peninsula, papua new guinea. | matschie's tree kangaroo (dendrolagus matschiei), new guinea pademelon (thylogale browni), and small dorcopsis (dorcopsulus vanheurni) are sympatric macropodid taxa, of conservation concern, that inhabit the yopno-urawa-som (yus) conservation area on the huon peninsula, papua new guinea. we sequenced three partial mitochondrial dna (mtdna) genes from the three taxa to (i) investigate network structure; and (ii) identify conservation units within the yus conservation area. all three taxa displaye ... | 2016 | 26006282 |
| successful management of hypertrophic cardiomyopathy in a matschie's tree kangaroo (dendrolagus matschiei). | a 3-yr-old, intact male matschie's tree kangaroo (dendrolagus matschiei) was examined for a 1-wk history of intermittent lethargy and tachypnea. an echocardiogram revealed concentric hypertrophy of the left ventricular free wall and interventricular septum. these findings were compared to measurements from healthy matschie's tree kangaroos, supporting a diagnosis of hypertrophic cardiomyopathy. at the time of publication, the patient has been managed for over 11.5 yr, using a combination of enal ... | 2015 | 25831580 |
| spatial requirements of free-ranging huon tree kangaroos, dendrolagus matschiei (macropodidae), in upper montane forest. | tree kangaroos (macropodidae, dendrolagus) are some of australasia's least known mammals. however, there is sufficient evidence of population decline and local extinctions that all new guinea tree kangaroos are considered threatened. understanding spatial requirements is important in conservation and management. expectations from studies of australian tree kangaroos and other rainforest macropodids suggest that tree kangaroos should have small discrete home ranges with the potential for high pop ... | 2014 | 24642914 |
| genetic evaluation of the association of zoos and aquariums matschie's tree kangaroo (dendrolagus matschiei) captive breeding program. | matschie's tree kangaroo (dendrolagus matschiei) is an endangered species that has been bred in captivity since the 1970s. in 1992, the tree kangaroo species survival plan(®) (tkssp) was established to coordinate the captive management of association of zoos and aquariums (aza) d. matschiei. the tkssp makes annual breeding recommendations primarily based on the mean kinship (mk) strategy. captive breeding programs often use the mk strategy to preserve genetic diversity in small populations-to av ... | 2011 | 22147592 |
| a multiplex pcr assay to distinguish among three sympatric marsupial taxa from huon peninsula, papua new guinea, using the mitochondrial control region. | matschie's tree kangaroo (dendrolagus matschiei) is an endangered arboreal macropodid marsupial that is difficult to locate in the wild. the tree kangaroo conservation program noninvasively collected d. matschiei faecal samples, but a high percentage of samples were misidentified and belonged to two terrestrial macropods, new guinea pademelon (thylogale browni) and small dorcopsis (dorcopsulus vanheurni). we developed species-specific primers that produced a unique sized mitochondrial dna contro ... | 2010 | 21565037 |
| genetic diversity in captive and wild matschie's tree kangaroo (dendrolagus matschiei) from huon peninsula, papua new guinea, based on mtdna control region sequences. | the association of zoos and aquariums (aza) matschie's tree kangaroo (dendrolagus matschiei) population is at a critical point for assessing long-term viability. this population, established from 19 genetically uncharacterized d. matschiei, has endured a founder effect because only four individuals contributed the majority of offspring. the highly variable mitochondrial dna (mtdna) control region was sequenced for five of the female-founders by examining extant representatives of their maternal ... | 2009 | 19504594 |
| seroprevalence of retrovirus in north american captive macropodidae. | laboratory records of serology results from captive macropodidae sampled between 1997 and 2005 were reviewed to assess the seroprevalence of retrovirus exposure. serum samples from 269 individuals (136 males, 133 females) representing 10 species of macropods housed in 31 north american captive collections were analyzed for retrovirus antibody using an indirect immunofluorescent assay. the prevalence of positive antibody titers comparing male versus female, between species, between age groups, an ... | 2008 | 18816994 |
| characterization of the estrous cycle and assessment of reproductive status in matschie's tree kangaroo (dendrolagus matschiei) with fecal progestin profiles. | the population of matschie's tree kangaroos (dendrolagus matschiei) held in north american zoos has declined to critically low numbers, and information on the reproductive biology of tree kangaroos is limited. the objectives of this study were to (1) characterize the temporal features of the estrous cycle through the measurement of fecal progesterone metabolite (i.e., progestin) concentrations and (2) determine the reproductive status of female tree kangaroos in the captive population of north a ... | 2008 | 18241863 |
