ZO24036Hospital admissions to a major wildlife hospital in south-east Queensland, Australia, over a 10-year period, 2012–2022

Kate J. Dutton-Regester

 

Wildlife hospitals play a vital role in caring for injured animals and revealing threats to local species. A study of 10 years of data from the RSPCA Wildlife Hospital in Brisbane found that orphaning, vehicle collisions, disease, and dog attacks were the main causes of admissions, with vehicle collisions having a major impact on koalas. These findings highlight the need for better conservation efforts to reduce these threats and protect wildlife in urban areas. Photograph by RSPCA Queensland Ltd.

ZO25015A new species of Phryssonotus (Diplopoda: Synxenidae) from north-eastern New South Wales, Australia

Cuong Huynh and Anneke A. Veenstra

 

Penicillate millipedes are tiny, soft-bodied arthropods under 5 mm long, lacking body calcification and covered in trichomes. Phryssonotus borealis is a newly discovered synxenid species from north-eastern New South Wales, Australia. It is distinguished taxonomically by having white tergal scale trichomes and by its unique genetic characteristics when compared to related species. Photograph by Cuong Huynh.

ZO24031Group structure in a social huntsman spider (Delena cancerides) reveals seasonal variation in group complexity

Vanessa Penna-Gonçalves

 

Spider social behaviour is a fascinating area of study that reveals how these often-misunderstood creatures interact. Research on the Australian huntsman spider (Delena cancerides) shows that its colonies can be quite diverse, especially in summer, with multiple adults and juveniles cohabiting and sharing prey. These findings challenge previous assumptions and suggest a more intricate social structure that could reshape our understanding of spider ecology and behaviour.

ZO24041Evaluation of parameters of health in Australian fur seal (Arctocephalus pusillus doriferus) pups during early and mid-lactation

Jessalyn J. Taylor , Rebecca R. McIntosh , Isabelle Charrier and Rachael B. Gray

 

This study assessed parameters of health in Australian fur seal pups at Seal Rocks (Victoria) in early (3–6 weeks) and mid-lactation (5–6 months). Results provide a baseline for health monitoring and highlight the increased vulnerability of younger pups during early lactation. This research informs understanding of pinniped health and management strategies. Photograph by Jessalyn Taylor.

ZO25006Molecular and morphological analysis confirms two additional species of python (Antaresia) on Cape York Peninsula, Queensland

D. J. D. Natusch , L. McIntyre, B. J. Muller and D. Esquerré

 

We examined molecular and morphological information from Antaresia pythons in northern Cape York Peninsula, Australia. We confirm the presence of two additional species from Cape York (Antaresia childreni and A. papuensis), making this region Australia’s hotspot for python diversity. Photographs by Daniel Natusch.

ZO25002The influence of season, habitat and diet on the faecal microbiome of the yellow-footed rock-wallaby (Petrogale xanthopus xanthopus)

The characterisation of Australian marsupials’ faecal microbiome is largely uncharted, but has previously been identified as an important component of conservation programs. This project examined the interaction between diet and faecal microbiome of yellow-footed rock-wallabies in South Australia, found that there are similarities with other Australia marsupials and that diet likely affects faecal microbial composition. Continuing to characterise the faecal microbiome of Australian marsupials will provide a valuable tool for their conservation as climate change worsens. Photograph by Stacey Dix.

ZO24034Population structure, growth and reproduction in two species of Tympanocryptis (Agamidae)

Lyn Nelson and Paul D. Cooper

 

Growth of two species of the endangered lizard in the genus Tympanocryptis (T. lineata and T. osbornei) from around the Canberra, ACT, and Cooma, NSW, respectively, is similar over three years, as is the population age structure. Individuals of each species are also able to survive over multiple years. Colour changes with reproduction in females is most obvious for both species in spring and autumn during the year for both species. Image Paul Cooper.

ZO24027Determination of population age structure from the survivorship of individuals of unknown ages in unicorns and platypuses

J. W. Macgregor , P. A. Fleming , O. Wade, R. Donaldson and K. S. Warren

 

Knowing the ages of animals in wild populations is important for conservation modelling. But for many species it is not possible to determine an adult individual’s age. By looking at how long individuals of unknown ages live, this report uses a hypothetical population of unicorns to illustrate a method of working out the proportion of animals in a population that are any particular age, and then applies the same method to a population of wild platypuses.

We conducted molecular identification of the highly depredated remains of a cetacean specimen found on a beach in the Jurabi Coastal Park, Western Australia. The specimen was identified as Shepherd’s beaked whale (Tasmacetus shepherdi). This represents the most northern occurrence record for this poorly known beaked whale species.

ZO24025GPS tracking informs nest reserve design for an endangered raptor, the grey goshawk (Tachyspiza novaehollandiae), in hostile anthropogenic landscapes

David A. Young and James B. Kirkpatrick

 

The grey goshawk (Tachyspiza novaehollandiae) is an endangered raptor whose spatial ecology is poorly known. We estimated home range size of 15 GPS tracked goshawks in Tasmania to assist with conservation management of the species. Home range size of male goshawks (160.50 km²) was eight times larger than that of females (19.03 km²). Image by David A. Young.

ZO24037Population differentiation in the white-fronted chat (Epthianura albifrons) at a continental scale: implications for dispersal, biogeography and conservation

Richard E. Major , Georgina M. Schlub, Rebecca N. Johnson , Andrew G. King and Gretel S. Major

 

Fragmentation of populations is a major concern for many threatened species. Population genetics can be used to identify barriers to dispersal and, in this study, revealed that small extents of ocean and urbanised land resulted in isolation of populations of the white-fronted chat. Conservation efforts for this species, listed as Vulnerable in NSW, must recognise that despite the powers of flight and a tendency towards nomadism, this species is not as dispersive as was previously believed.

ZO24030Rocky landform specialists of the Mount Isa Inlier: camera trapping reveals seasonal occupancy and habitat associations of a unique faunal assemblage in an ancient landscape

Jarrad C. Barnes , Elizabeth A. Brunton, Mark G. Sanders and Christofer J. Clemente

 

We conducted a 13-month camera trap study investigating when and how a diverse fauna utilises the ancient and complex rocky landforms of the Mount Isa Inlier. We found a unique rocky landform specialist community that utilised the landscape at different rates throughout the year, and favoured certain slope aspects, landform types, and lithologies. Our results highlight the best times of year and the environmental characteristics of sites in which to focus future management and conservation initiatives for this unique community.
