This study investigated the abundance and detectability of forest owls in south-western Australia. Boobooks occurred 23 times (48% of nights) and the masked owl once in 42 surveys. Tawny frogmouths were detected three times. These results are considered with two other investigations of forest owls in the region.

Yellow-spotted goannas (Varanus panoptes) are the main turtle nest predators at the Wreck Rock rookery, adjacent to Deepwater National Park in south-east Queensland. Examination of space-use patterns indicates that it is the larger male yellow-spotted goannas that are the main predators of sea turtle nests at the Wreck Rock beach-nesting aggregation.

ZO16087No evidence of protracted population decline across 17 years in an unmanaged population of the green and golden bell frog in north-eastern New South Wales
Describing the population trends of threatened species is central to conservation. We conducted mark–recapture modelling for a population of green and golden bell frogs in two periods, 17 years apart. There was no evidence this unmanaged population was in decline. We highlight factors that may cause bias in population modelling.

We conducted a morphometric analysis of Crocodylus johnstoni and present formulae which allow the accurate reconstruction of C. johnstoni from measurements of individual body parts. We also compared relative growth in C. johnstoni to that in other species of crocodile and discuss possible ecological correlates of observed differences.

The breeding seasonality of female dingo–dog hybrids was investigated. Ovary follicular phase was characterised by growing follicles in late summer and autumn. Characteristics of uterus pregnancy were observed in winter and coincided with a peak of corpus luteum. Overall, the data show that hybrids have a single annual breeding season in winter, exhibiting the same breeding seasonality as dingoes.
ZO16063Ecology of the rare but irruptive Pilliga mouse, Pseudomys pilligaensis. V. Relationships with yellow-footed antechinus, Antechinus flavipes, and house mouse, Mus domesticus
We investigated relationships between Pseudomys pilligaensis and other small mammals in terms of their population fluctuations and habitat selection during its irruption. It is suggested that Mus domesticus was possibly excluded from our sites through competition with P. pilligaensis. This study provides ecological information which can contribute to effective management planning for P. pilligaensis.

ZO17025Effect of flow on platypus (Ornithorhynchus anatinus) reproduction and related population processes in the upper Shoalhaven River
The occurrence of high poststorm discharge in the period when juveniles are confined to nesting burrows was the best predictor of platypus reproductive failure in the unregulated upper Shoalhaven River. In contrast, a significant positive linear relationship was identified between percentage lactation and antecedent March–July flow.

ZO17053Isolation and characterisation of microsatellites for the endangered Slater’s skink, Liopholis slateri (Squamata : Scincidae), via next-generation sequencing
We characterised 14 new polymorphic microsatellite loci for the endangered lizard, Liopholis slateri. In addition to the reporting of new markers, we used scats as a source of DNA for subsequent genotyping. Gaining genetic information from scats will help advance our knowledge of this threatened species through non-invasive means.

ZO16028Dietary composition and prey preference of a new carnivorous marsupial species, the buff-footed antechinus (Antechinus mysticus), at the northern and southern limits of its range
We examined diet composition and prey preference of the buff-footed antechinus (Antechinus mysticus) in its southernmost and northernmost populations. Diet was dominated by Araneae (spiders), Blattodea (cockroaches) and Coleoptera (beetles). A. mysticus is evidently a dietary generalist, opportunistically consuming mostly invertebrate prey with supplementary predation on small vertebrates.

Southern elephant seals typically breed on subantarctic islands. We report on the successful weaning of a female southern elephant seal in Western Australia born to a first-time breeding mother in November 2016. This seal (1.42 m long, nose-to-tail length) fell within the lower quartile of weaning sizes and has low first-year survival prospects (20–35%).

We present a database of terrestrial mammal records on Western Australian islands that includes records of 88 indigenous species on 155 islands, compared with 54 indigenous species on 141 WA islands in Abbott and Burbidge (1995). The database also provides 266 records of 21 species of non-indigenous mammal species on 138 WA islands.
Marsupials are not generally regarded as nest-predators of birds. Three marsupials – boodie (Bettongia lesueur), woylie (B. penicillata) and brushtail possum (Trichosurus vulpecula) – were identified taking eggs from artificial ground nests. Dietary evidence of bettongs consuming vertebrates, including live prey, is presented.

ZO17017Seasonal effects on body temperature of the endangered grassland earless dragon, Tympanocryptis pinguicolla, from populations at two elevations
Populations of the endangered grassland earless dragon, Tympanocryptis pinguicolla, from two elevations were compared for seasonal preferred temperature in a laboratory temperature gradient and in the field using radio-telemetry and chest temperature measurements. These data and operative temperatures in various microhabitats indicate that these lizards are moderate thermoregulators.

ZO17004Demographic parameters of the squirrel glider (Petaurus norfolcensis) in an urban forest remnant
Effective management of species requires detailed knowledge of key population parameters. We conducted capture–mark–recapture of the squirrel glider (Petaurus norfolcensis). The overall probability of annual apparent survival was 0.49 ± 0.08. Estimates of population size varied markedly over our 4-year study, but suggested this population near Brisbane was in decline.
