Agent Based Modelling of Auxin Transport Canalisation
… agent-based simulations of auxin transport canalisation. Auxin transport canalisation is the dominant theory describing how auxin promotes its own transport through a tissue from a site of auxin biosynthesis to an auxin sink. Directional transport of auxin through plant tissues is mediated …

Regulatory dynamics of axillary bud competition in Arabidopsis
… to systemic regulation via auxin transport canalisation, local regulation in the bud by the transcription factor BRANCHED1 (BRC1), has an important role in maintaining bud dormancy. However, its relationship to auxin canalisation-based regulation is poorly understood. This is particularly …

Environmentally-sensitive river management : assessment and mitigation of impacts on urban rivers
… caused by urban development, channelisation and canalisation. It then suggests possible measures to mitigate the impacts at the levels of the catchment, floodplain and river channel. The present cycle of degradation of urban rivers in the Cape Metropolitan Area (and elsewhere) can be halted. In …

Long-term change in the invertebrates of Zandvlei Estuary, with focus on the invasive reef worm Ficopomatus enigmaticus
… including the construction of a rubble weir, canalisation of the Estuary mouth, construction of a marina and hardening of the banks with concrete. These changes have facilitated the expansion of an invasive reef-building polychaete, Ficopomatus enigmaticus. This study quantifies long term …

Developmental, ecological and biological drivers of macroevolutionary trajectories of postcranial morphological diversification in bats
… humeral prenatal development, suggesting the canalisation of asymmetry throughout development. I uncovered decoupled patterns of humeral phenotypic variability and scaling across foraging and roosting guilds, as well as a diaphysis-epiphyses modular partition of humeral shape variation. …

Procedures and methods utilised by social workers within Gauteng during the selection process of prospective foster parents
… 3: Investigation; Theme 4: Foster committee and canalisation of reports; Theme 5: Children's Court. Section D comprises the final conclusions, limitations and recommendations of the research study. Section E includes addenda that were relevant to the research study

Dissecting the spatio-temporal development of the human reproductive tract
… pinpointing candidate genes involved in urethral canalisation of the penis, with direct relevance to the developmental origins of hypospadias. By integrating histological features with gene expression and chromatin accessibility data, I defined the transcription factors and cell signalling events …

Conservation ecology of the Cape clawless otter, Aonyx capensis, in an urban environment
… with optimal habitat that has been fragmented by canalisation and urban development. Road-killed otters showed signs of accumulation of PCBs in liver tissue suggesting that despite otters being adaptable generalists, their dependence on polluted freshwater systems may have long-term health …

The role of strigolactone and auxin in the regulation of shoot branching
Shoot branching is an essential ecological and agronomical trait regulated by the complex interaction of many signals, of which phytohormones are among the main actors. In this thesis I investigate the role of strigolactone and auxin in controlling bud growth dynamics and their effect on plant …

Adaptation at High Altitudes: A Comparative Analysis of Body Size and Proportions in Ancient Tibetan and Lowland Chinese Populations
… remained relatively elevated, perhaps due to canalisation or gene flow from cold-adapted northern populations. Climatic variables, particularly minimum precipitation, are positively associated with limb length, while spatial residuals imply unmeasured genetic or cultural factors also have a …

Bioaccumalation of metals in mullet from Mhlathuze Estuary and the effect of Cu and Pb on the uptake kinetics,haematology and acid-base balance of Liza dumerelii.
… development. The disturbance took the form of canalisation and redirection of Mhlathuze River and cutting of the new mouth after the berm wall was erected. These were drastic changes, which had a profound influence on the sanctuary (estuary). Resultant changes included siltation of the estuary …
