The A.thaliana receptor-like kinase PERK13 guides root hair tip growth and controls cell wall composition during pH-related stress
Plant root hairs are tubular shaped cells emerging from the outermost cell layer of the root. They substantially extend the root surface, thereby optimise the plant’s capacity to absorb water and nutrients. Root hairs, ...
Evolution of communication: a comparison of investment in chemical sensory systems of behaviourally diverse bees
To understand how group living has evolved we must understand how these societies are maintained. Communication is essential to social life – it is used to coordinate mating, reproduction, aggression, and to define group ...
Fitness trade-offs involved in adaptation to host plants, diapause-egg phenotypes and pesticides pressure in the redlegged earth mite, Halotydeus destructor
The redlegged earth mite, Halotydeus destructor, is an invasive species introduced into Australia from South Africa. In Australia, this species enters summer diapause at the egg stage which can survive desiccation, heat ...
Exploring the transition of primary to secondary cell walls
Plant cell walls are essential for plant growth and development, and they also provide food, feed and raw material for textiles, timber and paper for human use. While all growing plant cells are surrounded by a primary ...
Characterization and mechanisms of a novel density-dependent death phenotype in Plasmodium falciparum
The malaria parasite Plasmodium falciparum encounters diverse environments throughout its asexual lifecycle, including high parasite densities during sequestration of trophozoites and schizonts in the microvasculature. ...
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 ...
Investigating the loci that contribute to convergent craniofacial evolution between the thylacine and canids
One of the most fundamental questions in evolutionary developmental biology is how phenotypic adaptations are controlled at the molecular level. One way we can address this question is by looking at examples of convergent ...
Molecular systematics of siphonous green Algae (Bryopsidales, Chlorophyta)
The evolutionary history of the siphonous green algae (Bryopsidales, Chlorophyta) was investigated using a combination of molecular techniques and phylogenetic inference methods. Analyses of chloroplast genomes of the order ...
The physiological effects of artificial light at night on the Australian black field cricket
The presence of artificial light at night (ALAN) is one of the fastest growing, most pervasive and, until recently, under-appreciated forms of global pollution. Current ALAN levels in urban environments are associated with ...
Genetic epidemiology of the Plasmodium falciparum reservoir of infection in Bongo District, Ghana
Malaria remains a major global health problem, with Plasmodium falciparum being the causative agent of the majority of malaria-related deaths and clinical cases in humans. This burden is largely concentrated in West and ...
