Title of thesisLandscape Transformation and fragmentation: setting the playing field for global change drivers in the Cape Floristic Region

Description:  Landscape transformation and habitat fragmentation pose direct threats to biodiversity mainly through habitat loss. However, indirect effects through their interaction with other global change drivers such as climate change and alien invasions create potential for much greater impacts on biodiversity. For example, species’ tracking of shifting climates is constrained by unsuitable matrix and long distances to suitable habitat. Similarly, fragmentation interacts with alien species invasions; increasing the invasability of natural habitats through edge effects and increased propagule pressure from the matrix. My research explores how landscape patterns such as fragmentation interact with other global change drivers and the implications for biodiversity in the CFR.

Title of thesisAn analysis of post-fire catchment erosion dynamics under different land cover types, Jonkershoek, Western Cape

Description: Water and sediment fluxes in a channel network are the most important processes involved in sculpting catchment morphology. The response of a system to these fluxes and resulting geomorphic signatures may vary across catchments. Differences may occur due to terrain, variation in burn severity, variation in channel conveyance efficiency and vegetation dynamics. As such, similar systems may respond differently under similar conditions. Research indicates that vegetation cover is one of the most important erosion-controlling factors as it provides surfaces that are resistant to erosion through root cohesion. When vegetation is removed (e.g. by wildfire), the susceptibility of surfaces to erosion increases until the cover re-establishes over time. However, further investigation is required elucidating the relative dominance of erosion-controlling factors and how different systems will respond to different elements. Langrivier and Tierkloof are two gauged catchments in the Jonkershoek Nature Reserve with contrasting vegetation cover, providing an ideal setting to test ideas about key controls on erosion and deposition at catchment scale. Here a spatially distributed numerical model (CAESAR-Lisflood) coupled with detailed fieldwork i.e. erosion plots, time-integrated sediment sampling, soil and vegetation surveys, will provide a systematic means of testing the relative effect of these variables as well as offer insight into the mechanisms that control catchment form and function. The aim of this study is primarily to improve knowledge and understanding about sediment fluxes at catchment scale. To achieve the above aim, the following objectives will be carried out: 1) to investigate the variation of erosion dynamics in two different landscape settings through the wet season 2) to investigate the nature and dynamics of fine sediment transfer through the main channel of Langrivier and Tierkloof catchments 3) to simulate the effects of different land cover types on erosion rates using a landscape evolution model. The key theoretical contribution would be an improved understanding of the controls on modern catchment geomorphology in the rugged Cape Fold terrain.

Title of thesis: Comparison of the IUCN Red List of Ecosystem, South Africa approach to ecosystem threat status assessment

Description: In South Africa, ecosystems listed as either Critically Endangered or Endangered are prioritized for conservation and efforts made to reduce the rate of ecosystem collapse and species extinction. Previous assessment were based on nationally accepted and scientifically rigorous framework, but the IUCN have recently published a new assessment framework that has subtle differences to the existing South African system.

Since the publication of the new IUCN standards for the Red List of Ecosystem (RLE), there is pressure for South Africa to comply such that the national assessment can be comparable with other assessments across the globe. Key concerns around changing assessment standards that may hamper South Africa (SA) from adopting the IUCN RLE include (i) differences in their underlying philosophy and purpose (including the policy context), (ii) differences in the assessment outcomes of the current state of South African ecosystems using the SA and RLE approaches, and (iii) the implications of differences in these outcomes for the conservation of biodiversity. As such this thesis aims to test the IUNC RLE criteria in a South African context, explore the potential concerns raised above and, where necessary, explore ways in which any critical differences may be reconciled.
