Characterizing native palatable legume and non-legume species in the rangelands of the Overberg area
(University of the Western Cape, 2020)The Overberg renosterveld rangelands of the Cape Floristic Region (CFR) has become well associated with commercial and communal agricultural practices, namely crop and livestock production. This Mediterranean region is ... -
Chemical investigation of some species of Amaryllidaceae from the Greater Cape Region of South Africa as a source of bioactive compounds
(University of the Western Cape, 2020)The family Amaryllidaceae is widely distributed in the southern hemisphere. Members of the family are well known for their content of pharmacologically active alkaloids and represent an important epicentre of Amaryllidac ... -
Chytridiomycosis in amphibian populations in the Western Cape, South Africa
(University of the Western Cape, 2002)There have been many cases reported of amphibian populations declining. These are often due to anthropogenic factors such as habitat destruction and pollution. However, some declines have not had an obvious cause and many ... -
Coastal marine heatwaves: Understanding extreme forces
(University of the Western Cape, 2017)Seawater temperature from regional to global scale is central to many measures of biodi- versity and continues to aid our understanding of the evolution and ecology of biolog- ical assemblages. Therefore, a clear understanding ... -
A comparative study of degeneration of the posterior limbs and girdles of some scelotes species.
(University of the Western Cape, 1981)The genus Scelotes was instituted by Fitzinger in 1826 and is represented by nineteen species and subspecies in Southern Africa (Fitzsimons, 1943) . Valuable contributions have been made to our knowledge of the Lacertilia ... -
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 ... -
Corporate Social Responsibility in the South African forestry industry – a Western Cape perspective
(University of the Western Cape, 2013)Globally plantation forestry plays a pivotal role in terms of timber production, ecological services and maintaining local livelihoods. In South Africa commercial forestry occupies a relatively small portion of the total ... -
Description and assessment of neuston 1 communities present in the South Indian Ocean
(University of the Western Cape, 2022)Animal communities living at the sea-surface are relatively poorly known, despite the fact that this biotope is globally distributed, it acts as an important nursery area for many commercially important taxa and supports ... -
Detecting patterns of upwelling variability in Eastern Boundary Upwelling Systems with special emphasis on the Benguela region
(University of Western Cape, 2020)Coastal upwelling is one of the most important oceanographic processes relating to ecosystem function at local and global spatial scales. To better understand how changes in upwelling trends may occur in the face of ongoing ... -

(University of the Western Cape, 2020)Coastal upwelling is one of the most important oceanographic processes relating to ecosystem function at local and global spatial scales. To better understand how changes in upwelling trends may occur in the face of ongoing ... -
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 ... -
Developing fixed-point photography methodologies for assessing post-fire mountain fynbos vegetation succession as a tool for biodiversity management
(University of Western Cape, 2020)Areas of high biodiversity and complex species assemblages are often difficult to manage and to set up meaningful monitoring and evaluations programmes. Mountain Fynbos is such an ecosystem and in the Cape of Good Hope ... -
The development, optimisation and evaluation of molecular methods to diagnose abalone tubercle mycosis (ATM) caused by Halioticida Noduliformans in South African abalone, Haliotis Midae
(University of the Western Cape, 2012)Land-based abalone aquaculture in South Africa started in the early 1990s and is based on the local species Haliotis midae. This industry expanded with great success over the last decade. In 2006 abalone exhibiting typical ... -
The diet and feeding ecology of the brown house snake, Boaedon capensis
(University of the Western Cape, 2022)African brown house snakes (Boaedon capensis) are widely thought to be dietary specialists that predominantly consume rodents. Given their ubiquitous distribution, these snakes potentially play an important role in ... -
The diet and feeding of the pelagic goby, sufflogobius bibarbatus, off Namibia
(University of the Western Cape, 2009)The general diet of Sufflogobius bibarbatus in the northern Benguela upwelling ecosystem was investigated from gut content analysis in two separate studies. The first study was conducted over two 48 h diel sampling stations ... -
The distribution of the desert rain frog ( Breviceps macrops) in South Africa
(University of the Western Cape, 2009)The desert rain frog (Breviceps macrops) is an arid adapted anuran found on the west coast of southern Africa occurring within the Sandveld of the Succulent Karoo Biome. It is associated with white aeolian sand deposits, ... -
Distributional and dietary overlap between two common squaloid sharks, squalus acutipinnis and squalus bassi, caught as bycatch off the coast of South Africa
(University of Western Cape, 2021)Squalus acutipinnis and S. bassi may be the most common dogfish species around South Africa, and show overlap in their latitudinal and bathymetric distributions. Even though these sharks are likely endemics, they are also ... -
Diversity and Zoogeography of South African Bryozoa
(University of the Western Cape, 2017)The taxonomic history of South African bryozoans is fragmented and outdated, with the majority of published works in the 20th Century. Sampling gaps exist in deep-sea regions and parts of the coastline, while existing ... -
