The function of female and male ornaments in the lovely fairy-wren
Ornaments like plumage colours or complex song are generally regarded as male traits that are shaped by sexual selection. By contrast, the factors that shape female elaborate traits have often been overlooked, though they ...
Predicting ectotherm life cycles under a variable climate: physiological diversity of matchstick grasshopper eggs and their ecological and evolutionary implications
Understanding the processes underlying the phenology and distribution of species is a key problem in ecology. These relationships are important for predicting the responses to species to environmental change. Phenology and ...
Testing the decline of the threatened New Holland Mouse (Pseudomys novaehollandiae)
Delineating the distribution of a threatened species is critical for identifying threats and guiding conservation management. The process is challenging, however, especially when a species is rapidly declining, and so ...
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. ...
