Spatialised ecosystem modelling to evaluate the influences of marine protected areas and provisioning ecotourism on the foraging and distributional response of top predators from Mossel Bay to Algoa Bay, South Africa
High trophic level ecosystem-regulating top predators are an important facet in the structure and functioning of the South-East coast of South Africa. This region is influenced by the warm, fast-flowing Agulhas Current, which make it a highly productive biodiversity hotspot. This consequently …

Modelling British Columbia’s ecosystems and avian richness using landscape-scale indirect indicators of biodiversity
… repeatable broad-scale methods for biodiversity modelling is an important goal to address as habitat loss, fragmentation and environmental degradation threaten our ability to maintain ecosystem and species diversity levels. Geospatial reviews of biodiversity monitoring have identified ecological …

Offshore power production and marine stakeholders: from understanding conflict to impact mitigation
… potentially leading to conflict. Using the Ecosystem Approach (EA) as a conceptual framework, this thesis aimed to answer the question: What is the potential for conflict between the marine renewable energy industry and marine stakeholders, and how can this be mitigated?<br/>The research …

Trophic models of the Benguela upwelling system : towards an ecosystem approach to fisheries management
… many upwelling areas. In the southern Benguela ecosystem, anchovy were dominant in the 1980s whereas sardine abundance increased in the 1990s. Mass-balanced models were constructed of the trophic flows in the southern Benguela ecosystem for 1980-1989 and 1990-1997 and in the northern Benguela …

The influence of sediment nutrient dynamics on the response of lake ecosystems to restoration and climate change
… predicting how, and over what time-scales, lake ecosystems will respond to future scenarios such as climate change, in-lake restoration or altered external nutrient loading. Through a sediment field study on 14 different lakes, and applications of complex lake ecosystem models to three New …

Measurements and modelling of eutrophication processes in Lake Rotoiti, New Zealand
… fundamentally important for predicting how lake ecosystems will respond to management scenarios and which management actions are most likely to be successful to improve lake health. Through a field study in a morphologically diverse lake in New Zealand, and the application of a lake ecosystem …

Walking the bridge from single- to multi-species approaches in Southern African fisheries management
… worldwide is in flux with calls for an EAF (Ecosystem Approach to Fisheries) needing to be balanced with the ongoing requirements to provide timeous and realistic assessment-based advice for management ( often with major economic and social consequences), that is typically based on …

Integrated process-based simulation of soil carbon dynamics in river basins under present, recent past and future environmental conditions
… To perform this assessment an eco-hydrological modelling tool was used and extended by a process-based description of coupled soil carbon and nitrogen turnover. The extended model aims at delivering sound information on soil C storage changes beside changes in water quality, quantity and …
