Abstract:

While preparing a review of published descriptions of copulatory behaviour in macropod marsupials (McLean, Lundie-Smith and Jarman 1993), we were surprised to find no description for one of the most studied species, the quokka (Setonix brachyurus, e.g. see Bradshaw 1983). Copulating quokkas have been seen previously by researchers (e.g. Kitchener 1970), but no account was given. Here we provide descriptions of copulatory behaviour in quokkas, and comment on levels of sexual behaviour and activity by quokkas in the wild and in captivity.

Abstract:

Non-invasive methods have the potential to circumvent problems associated with using more traditional techniques when surveying for rare and elusive species. In this study, non-invasive molecular-based methods have been used to analyse the scats of several species of marsupials. DNA was successfully extracted from scats of the quokka, Setonix brachyurus, and three other macropods (Macropus fuliginosus, M. irma and M. eugenii) sympatric with the quokka and with similar-appearing scats. Partial sequence from the mitochondrial cytochrome b gene from these four species and seven other macropods wa

Abstract:

Understanding the spatial structure of populations is important in developing effective management options for threatened species, and for managing habitat connectivity for metapopulation function, and for demographic and genetic heterogeneity. We used genetic information to investigate the structure of populations of the quokka, Setonix brachyurus, in south-west Western Australia. We hypothesised that movement between known populations would be relatively rare and result in significant genetic structuring. Genetic analyses from 412 adult individuals at 14 nuclear markers (microsatellite) from

Abstract:

The quokka (Setonix brachyurus), an iconic marsupial endemic to Western Australia, is listed as vulnerable. It is found at its greatest abundance on Rottnest Island, where little is known about its home range and movement patterns. We estimated the home ranges of 22 male and 23 female quokkas within each season in four habitat types on Rottnest Island: coastal dune, grass/heath, woodland and settlement areas developed for tourism. We also tested for factors affecting home range and space use. The mean seasonal home-range size of quokkas was 1.91 ± 0.23 ha, and there was no effect of sex or wei

Abstract:

The quokka (Setonix brachyurus) exists in spatially restricted populations in the northern jarrah forest in south-west Western Australia. Observations were made of adult male quokkas exhibiting morphological anomalies (cryptorchidism and micropthalmia) that may be indicative of inbreeding within these populations. Despite the presence of males with abnormalities that could potentially affect their fertility, most females captured were carrying a pouch young or feeding a joey at foot. Field researchers and managers should routinely report abnormalities seen in wild captured animals. Reduced gen

Monitoring populations of threatened species plays a part in continued conservation and contributes to assessment of how effective management actions are. We estimated population indices and studied cohort demographics of mainland populations of quokkas (Setonix brachyurus) at 14 sites across the northern jarrah forest. One site is currently monitored through annual trapping, seven were intensively surveyed a decade previously, while six sites had no previous monitoring. Across the 14 study sites, no quokkas were detected at one site and the other population estimates ranged from 5 to 25 adult

The diet of the quokka in the northern jarrah forest of Western Australia was investigated by microscopic examination of faecal pellets of known individuals and comparison with a reference collection of plant epidermal tissue. Twenty-nine plant species were identified from the 97 faecal pellet groups collected from 53 individuals, confirming that the quokka is a browsing herbivore that favours leaves and stems. Of those 29 species, 11 made up over 90% of the diet and five species accounted for 71%. Thomasia species were the most common in the diet and the most preferred; Dampiera hederacea was

We investigated the consumption of milk by the young quokka using the stable isotope deuterium oxide. The volume of milk consumed increased from 1.6 mL day–1 at 55 days post partum to 32.5 mL day–1 at 165 days. The daily energy intake ranged from ~22 to 151 kJ day–1 during pouch life. The crude growth efficiency (grams of growth per millilitre of milk consumed) increased from an average of 0.35 to 0.46 g mL–1 in the early stages of pouch life, and then decreased to 0.24 g mL–1 during Phase 2b of lactation.

Abstract:

The amount of time allocated to vigilance, foraging, and locomotion as a function of group size were studied in the quokka (Setonix brachyurus), a small, moderately social, macropodid marsupial, on Rottnest Island. Despite living in isolation from most predators for up to 7000 years, quokkas exhibited typical group size effects of aggregation: they foraged more and showed less visual vigilance as group size increased. Group size effects, therefore, may result from factors other than antipredator benefits. In groups larger than 10, quokkas, uniquely among macropodids, allocated virtually all of

Abstract:

This study explores how curvature in the quokka femur may help to reduce bending strain during locomotion. The quokka is a small wallaby, but the curvature of the femur and the muscles active during stance phase are similar to most quadrupedal mammals. Our hypothesis is that the action of hip extensor and ankle plantarflexor muscles during stance phase place cranial bending strains that act to reduce the caudal curvature of the femur. Knee extensors and biarticular muscles that span the femur longitudinally create caudal bending strains in the caudally curved (concave caudal side) bone. These

The presence or absence of quokka populations at 66 sites in the northern jarrah forest of Australia was investigated using generalised linear models (GLM). We hypothesised that fox control and the presence of a mosaic of post-fire seral stages within Agonis linearifolia swamp vegetation were important in predicting the presence of quokkas. The number

The potential for the quokka (Setonix brachyurus (Quoy & Gaimard, 1830)), a threatened macropodid marsupial, to increase in abundance following the initiation of predator control was investigated by determining the cause of deaths of radio-collared individuals. Predation was identified as a major cause of death followed by road kills. The non-parametric Kaplan–Meier method modified for staggered entry of individuals was used to estimate survivorship. Although males and females were affected differently by each cause of mortality, their overall survivorship did not differ significantly. Ind

Abstract:

A study was conducted to determine the validity of using transect counts of faecal pellet groups to estimate population densities of a threatened, macropodid marsupial – the quokka (Setonix brachyurus (Quoy & Gaimard, 1830)). Mark–recapture estimates of population density were regressed against counts of faecal pellet groups at six sites with and three sites without fox control within the northern jarrah forest of Western Australia. Significant linear relationships were found between population density and pellet counts for all sites (r2 = 0.56, P < 0.02) and when all unbaited sites wer

Abstract:

Prescribed burning is frequently advocated as a means of managing habitat for threatened species. We studied effects of fire on the quokka (Setonix brachyurus), a species currently used as a focal species for planning prescribed burns in the southern forests of Western Australia. We examined (i) the recolonisation of burnt areas; (ii) the refuge value of unburnt vegetation; and (iii) fire prediction variables that may help to guide fire planning to achieve desired habitat management outcomes. We hypothesised that fire regimes promoting vegetation structure and patchiness of burnt and unburnt v

Abstract:

Variation in five external morphological characters was examined among two island populations and five remnant mainland populations of the quokka, Setonix brachyurus. Sexual dimorphism was observed, with males being significantly larger than females at each location. Pairwise comparisons among populations showed that significant differences were mostly between the two island populations. There was a general trend for animal size to decrease with latitude. Multivariate analyses did not show clear geographic groups, although the island populations tended to cluster. The inheritance of the morpho
