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 ... -
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 ... -
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 ... -

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 ... -
Documenting the association between a non-geniculate coralline red alga and its molluscan host
(University of the Western Cape, 2010)To further investigate the strength of the association and the relative advantages of the association to both organisms, several manipulation experiments were set up. A cage experiment set up in the shallow subtidal zone ... -
Dynamics and biological implications of the Port St Johns cyclonic lee eddy
(University of the Western Cape, 2016)This project describes the current dynamics of the cyclonic lee eddy off Rame Head, Port St Johns and Waterfall Bluff, and how its physical forcing may influence the biological communities. Three research surveys were ... -
Ecklonia maxima kelp forests along a thermal gradient: community composition and recovery from disturbance
(University of the Western Cape, 2017)Climate change will influence species distributions, survival and ecosystem functioning, mostly through changes in sea surface temperatures and storm disturbance. Species are expected to shift poleward in response to ocean ... -
Ecology and diet of the caracal (Caracal caracal) on lethal and non-lethal control farms in the Karoo
(University of the Western Cape, 2020)Human-wildlife conflict is an ongoing issue worldwide. Within South Africa, human-carnivore conflict (HCC) as a result of carnivore depredation on small-livestock causes large-scale losses, and promotes the use of predator ... -

The effect of copper on the growth, development and chemical composition of some dryland wheat cultivars
(University of the Western Cape, 2005)Heavy metal accumulation in arable land as a result of mining activities, pesticides and fertilisers has become a global concern. Steinkopf and Concordia in the Northern Cape are well-known for subsistence farming, but ... -
The effect of exogenous growth regulators on salinity tolerance in Erucastrum strigosum
(University of the Western Cape, 2003)Randomized block experiments were conducted to examine the putative amelioratory effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in Erucastrum strigosum plants subjected to a salinity ...
