ZO25023Helox suggests advective ventilation of the insect tracheal system during discontinuous gas exchange

Waseem Abbas , Philip C. Withers and Theodore A. Evans

 

We compared gas exchange for two insects varying in the absence (red flour beetle) or presence (cockroach) of air sacs, using 21% oxygen in helium to increase the diffusion rate relative to normal air. Contrary to theory, gas exchange of the small red flour beetle was mainly advective, enhancing our physiological understanding of this pest beetle with implications for its pest management.

ZO25024The Southern Angle-headed Dragon (Lophosaurus spinipes): a systematic review of the literature

Bradley J. Traynor , Heike Schütze , Darryl L. Houston , Harold Heatwole and Eric J. Nordberg

 

The Southern Angle-headed Dragon (Lophosaurus spinipes) is a cryptic agamid endemic to the warm-temperate and subtropical rainforests of south-eastern Australia. We conducted a systematic literature review to synthesise information relevant to its potential conservation in the face of predicted climatic change. There is limited empirical data on L. spinipes; more research on population sizes, trends over time, thermal properties of the microclimate, thermal limits, and metabolism, with a focus on rising environmental temperatures, is required to underpin conservation decisions.

ZO25009Science meets the taipan: the discovery and description of an iconic venomous snake

Kevin Markwell and Richard Shine

 

Warning: Aboriginal and Torres Strait Islander people should be aware that this publication contains images of deceased persons, and discussion of historical events which may be deemed culturally sensitive.

We explore the history of the taipan’s ‘discovery’ by Western scientists, and early attempts to classify the species. Our analysis of historical documents reveals a much greater role for First Nations people in collection of the first taipans known to science; and identifies reasons why this giant snake remained poorly understood for many decades. Photographs by Rob Valentic and Ray Sumner.

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.

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.
