Biochemical mechanisms of biomineralization and elemental incorporation in otoliths: implications for fish and fisheries research
All vertebrates have small bioinorganic “earstones” in their inner ear labyrinth that are essential for hearing and balance. While otoliths play a vital anatomical role in fish, their true value to science is as biochronometers, ...
Novel gene therapy for the treatment of diabetes-induced heart failure
People with diabetes are at risk of developing myocardial abnormalities known as diabetic cardiomyopathy. This is characterised by diabetes-induced left-ventricular (LV) impairment, which develops independent of hypertension, ...
Taxonomy, ecology and conservation genomics of North-Eastern Australian Earless Dragons (Agamidae: Tympanocryptis spp.)
Land clearing and modification of natural habitats is threatening biodiversity globally. In Australia, most native grassland habitats have been heavily modified for agriculture, including cropping and grazing. Grassland ...
Spiders of wheat agroecosystems of southern Victoria, Australia
Spiders are important predators of insects in all terrestrial ecosystems. Their great diversity, broad diet and varied foraging strategies make their role in food webs complex and dynamic and are therefore not an easy group ...
Breeding biology of the platypus (Ornithorhynchus anatinus)
This thesis examines the different behavioural stages of the reproductive cycle in the platypus, Ornithorhynchus anatinus, the time and energy investment of the female in breeding, and use of burrows by wild juveniles ...
The role of web-based chemical communication in the mating and foraging strategies of the orb web spider Argiope keyserlingi
Chemical communication is critical in shaping the interactions of individual animals, both within and between species. Pheromones (species-specific chemical signals) occur in all species and arguably contribute to more ...
Defining the master regulator of urethral closure in mouse
Hypospadias is the ectopic placement of the urethral opening on the underside of the penis and is one of the most common developmental abnormalities in humans, occurring in approximately 1 in every 125 live male births. ...
Triple jeopardy in the tropics: assessing extinction risk in Australia's freshwater biodiversity hotspot
Freshwaters are the most degraded and imperiled ecosystem globally. Despite this high vulnerability, conservation efforts in freshwaters often lag behind those in terrestrial and marine ecosystems. In Australia this is ...
Cognitive bias as an indicator of emotional state and welfare in captive zebrafish
Concerns regarding animal welfare are ultimately predicated on the assumption that animals can experience subjective feelings, which are the prerequisite to experiencing suffering, pain and pleasure. Assessing the subjective ...
Defining the role of endogenous estrogen in penile urethral development
Hypospadias, the ectopic placement of the urethral meatus along the ventral aspect of the penis, is one of the most common birth defects in boys. The prevalence of hypospadias has increased in recent decades, a phenomenon ...
