Angiostoma margaretae n. sp. (Angiostomatidae) is described from the oesophagus of the slug Milax gagates Draparnaud collected near Caledon in the Western Cape Province of South Africa. The new species closely resembles ...
Applying a resilience approach to flood management in rapidly changing landscapes

Ilse, Kotzee (Stellenbosch : Stellenbosch University, 2016-12)

ENGLISH ABSTRACT: Human land use activities have significantly changed the capacity of ecosystems to deliver essential service. Additional stresses brought about by climate change will require a shift in how ecosystems are ...
Approaches towards a critical evaluation and update of the red list of South African Butterflies

Ball, Johathan Bradford (Stellenbosch : University of Stellenbosch, 2006-03)

Using the World Conservation Union’s (formerly the International Union for the Conservation of Nature) IUCN 2001 categories and criteria, the conservation status of the South African butterfly fauna has been reassessed. ...
Arthropod communities of Proteaceae with special emphasis on plant-insect interactions

ENGLISH ABSTRACT: Arthropod communities of five proteaceous species viz. Protea repens. P. neriifolia. P.cynaroides, Leucospermum cordifolium and Leucadendron /aureolum were studied. A faunal list of the insects was compiled ...
Arthropods associated with commercial Proteaceae in the Western Cape Province, South Africa

Sasa, Archbold (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: The commercial cultivation of Proteaceae is an important industry in the Western Cape, however, farmers are challenged with arthropod infestation which compels them to solely rely on chemical pesticides. ...

An assessment of different beekeeping practices in South Africa based on their needs (bee forage use), services (pollination services) and threats (hive theft and vandalism)

Masehela, Tlou Samuel (Stellenbosch : Stellenbosch University, 2017-03)

ENGLISH ABSTRACT: Two honey bee subspecies indigenous to South Africa, Apis mellifera capensis Escholtz (Cape honey bee) and Apis mellifera scutellata Lepeletier, are actively managed by beekeepers for honey production, ...
Assessment of fish as bio-indicators of river health in rivers of the southwestern Cape

Hayes, Johan Barnard (Stellenbosch : Stellenbosch University, 2002-03)

ENGLISH ABSTRACT: In this study, the Fish Assemblage Integrity Index (FAll) was applied on three rivers within the southwestern Cape. This index uses fish as indicators of biological aquatic integrity and is based ...
Assessment of quantitative and genetic molecular variation of Acacia karroo in two extreme populations

Bayonne Mboumba, Georges (Stellenbosch : University of Stellenbosch, 2006-03)

Acacia karroo is widespread in southern Africa and displays remarkable phenotypic plasticity over its geographical range. However, it is currently unknown whether this phenomenon is merely phenotypic variation due to ...
Assessment of the alien marine intertidal invertebrates in the Kogelberg Biosphere Reserve, South Africa

Malherbe, Hanlie (Stellenbosch : Stellenbosch University, 2011-12)
