Disturbance factors related to conservation of biodiversity in large-scale ecological networks
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Globally, habitat transformation causes biodiversity loss, with the transformed matrix often affecting the disturbance regime in remnant natural patches. In South Africa, significant parts of the Indian ...
An investigation of the evolutionary diversification of a recent radiation of dwarf chameleons (Bradypodion) from KwaZulu-Natal Province, South Africa
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: An important prerequisite for evolutionary change is variability in natural populations;
however, when phenotypic and molecular rates of change differ, species delimitation is
problematic. Such discordance ...
Exploring meaningful nature experience, connectedness with nature and the revitalization of transformative education for sustainability
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Humanity‘s growing separation from nature is central to the convergent social and ecological crises facing earth. This is both a psychological (e.g. perceptual, emotional) and physical (e.g. experiential) ...
Plant response to habitat fragmentation : clues from species and functional diversity in three Cape lowland vegetation types of South Africa
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: The South African Cape lowlands have been severely transformed and reduced to fragments embedded in matrices of various activities. With the need to prioritise conservation efforts, information on the ...
Pollination ecosystem services to onion hybrid seed crops in South Africa
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Insect pollination contributes in various degrees toward the production of a variety of
agricultural crops that ensure diversity and nutritional value in the human diet. Although
managed honeybees (Apis ...
The conservation value of habitat remnants for flower visiting insects in the lowlands of the Cape Floristic Region

ENGLISH ABSTRACT: See full text document for abstract
Links between lateral riparian vegetation zones and flow
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: Riparian vegetation communities that occur along perennial rivers are structured in lateral
zones that run parallel to river flow. This dissertation investigated the structure of South
African riparian ...
Grasshopper bioindicators of effective large-scale ecological networks
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Land use change is leading to rapid biodiversity loss in terrestrial ecosystems worldwide. Ecological
networks (ENs) are systems of remnant natural habitat which remain intact in a transformed matrix,
and ...
Restoration ecology of the Seychelles giant millipede
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The loss and degradation of habitat is recognised as the greatest threat to invertebrate biodiversity. Restoration practices have the potential to reduce these impacts. The Seychelles giant millipede ...
Effects of vineyard management and landscape context on taxonomic diversity and interaction networks of flower-visiting insects in the Cape Floristic Region biodiversity hotspot
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Both taxonomic diversity and diversity of species interaction networks are experiencing
declines as a result of agricultural intensification at habitat and landscape scales. Reversing
this trend is a ...
