The mean incidence of periparturient mortality reported in Merino ewes ranges from 0.3% to 11.4%. However, there are challenges with reporting mortality figures in extensive production systems due to the nature of record keeping and farm characteristics.

The aim of the study was to identify prognostic factors for koalas affected by bushfire. Koalas (n = 199) were grouped based on their burn status in combination with their burn bandaging requirement at triage; those with no burns, with burns that did not require bandaging and with burns that did require bandaging. Overall, 59.8% of koalas had positive outcomes, but this reduced to only 13% of koalas in the most severely affected group (burns that were bandaged). Negative outcomes were found to be associated with several factors, including the timing of presentation, with the worst affected animals presenting in the first 2 weeks of the operation. Also, an increasing number of bandage changes during hospitalisation led to increasingly negative outcomes, with no positive outcomes beyond three bandage changes. In addition, clear associations were found with patterns of burns on feet, with only 4% positive outcomes for animals with all 4 feet burnt. All bandaged koalas with severe dehydration had negative outcomes and body weights decreased over time for hospitalised animals from the most severely affected bandaged burn group. Mild serum sodium concentration elevation at triage was the only clinically significant blood abnormality for koalas with bandaged burns.

Historically, these samples have been obtained through recreational and commercial fisheries or via fisheries-independent sampling, often involving lethal methods. However, with a significant number of elasmobranch species listed as conservation concerns under IUCN standards - approximately one-third of species are threatened with extinction - there is an urgent need for nonlethal tissue sampling techniques to optimise animal care and further conservation research. Recent advances have demonstrated nonlethal liver sampling in teleost fishes, but this has rarely been attempted in elasmobranchs. Yet, in elasmobranchs, the liver is one of the largest organs, performing critical functions such as buoyancy regulation, energy storage and metabolic processes. Here, we present a nonlethal liver biopsy procedure in an elasmobranch species, the epaulette shark (Hemiscyllium ocellatum). Individual sharks were wild-collected from coastal waters of Queensland, Australia and maintained in holding facilities at James Cook University and Heron Island Research station where all procedures took place. Following surgery, the sharks made a full recovery, accepted food within 24 hours, and were monitored for 2 weeks before being released back to their original collection sites after complete healing.
