(University of the Western Cape, 2017)
Bladder grasshoppers (Orthoptera: Pneumoridae) are nocturnal African herbivores that are
endemic to the coastal regions of southern Africa. They rely heavily on sound communication
for mate location and have a unique body ...
Conservation and resource-use relations: Analysis for protected area expansion feasibility in the Western Cape
(University of the Western Cape, 2022)
It is assumed that expanding the size and/or number of protected and conservation areas can contribute
to more effective conservation, ecosystem services and environmental protection. Expansion is
normally a response to ...
Snake community structure in a heterogeneous fynbos ecosystem
(University of the Western Cape, 2022)
Snakes occur in most terrestrial ecosystems, forming an integral part of many ecological
communities. A diverse community of snakes in an ecosystem can indicate a complex habitat
structure capable of supporting a diverse ...
Detection of phycotoxins along the South African coast: a comparison of three different biological assay systems and instrumental analysis by high performance liquid chromatography
(University of the Western Cape, 1998)
In recent years, harmful algal blooms have been of growing concern in many parts of the world. These blooms often result in deterioration in water quality, large-scale mortalities in marine life, and shellfish poisonings ...
Understanding mangrove dynamics in range edge populations in South Africa
