Food resources available to juvenile fish (particularly rhabdosargus holubi) in seagrass beds of the swartkops etuary
(University of the Western Cape, 2023)Estuarine habitats are critical nursery areas for many species of marine fishes during their early life stages in terms of food availability and structural complexity, which increases survival and growth rates. The Cape ... -
Foraging ecology of Naja nivea and Dispholidus typus
(University of the Western Cape, 2019)It is widely reported that snakes can be major predators of avian nests, but the use of a single avian prey type by competing species has rarely been examined. This study aimed to investigate predation of a single food ... -
Functional importance of snakes in a strandveld ecosystem
(University of the Western Cape, 2018)Gaps in our knowledge of the functional roles of snakes within ecosystems limit our ability to predict the potentially cascading effects their removal from an ecosystem might create. Extirpation of snake species could ... -
Genetic analysis of resistance to powdery mildew (podosphaeara leucotricha) in apple (Malus x dornestica Borkh.)
(University of the Western Cape, 2008)Apple powdery mildew, caused by Podosphaera leucotricha, is one of the major diseases of the cultivated apple in the Western Cape, causing severe losses in yield and affecting fruit quality. This affects the deciduous ... -
Genetic analysis of the Cape Sand Frog, Tomopterna delalandii (Tschudi 1838)
(University of the Western Cape, 2015)Tomopterna delalandii occurs throughout the west coast, Western Cape and south coast of South Africa. This range stretches across three distinct biogeographical assemblages. Based on historical records and the fact that ... -
Genetic and morphological comparisons within the orthopteran family Pneumoridae
(University of the Western Cape, 2019)Bladder grasshoppers belong to the order Orthoptera, ancient family Pneumoridae and Superfamily Pneumoroidea. This small group of grasshoppers are sound producing, nocturnal, herbivorous grasshoppers endemic to the coastal ... -
The genus Spongites (Corallinales, Rhodophyta) in South Africa
(University of the Western Cape, 2019)Coralline red algae (Corallinales, Hapalidiales, Sporolithales: Corallinophycidae, Rhodophyta) are widespread and common in all the world’s oceans (Adey & McIntyre 1973; Johansen 1981; Littler et al. 1985; Björk et al. ... -
A global revision of the nongeniculate coralling algal genere Porolithon Foslie (defunct) and Hydrolithon Foslie (Corallinales, Rhodophyta)
(University of the Western Cape, 2005)The purpose of this thesis was to provide a revision and characterization of the species of nongeniculate coralline algae previously ascribed to the now defunct genus Porolithon; to provide a modern account of selected ... -
Granivores as ecosystem regulators of woody plant increasers in semi-arid Savannas of the Lowveld, South Africa
(University of the Western Cape, 2006)In recent years, a global trend of increasing woody vegetation densities in semi-arid savanna habitats has been recorded, commonly described in South Africa as 'bush encroachment'. The shrubs and trees that do this ... -
Growth of juvenile abalone under aquaculture conditions
(University of the Western Cape, 2006)The aim of this research was, first to test the suitability of different seaweeds and formulated feeds as food for post-weaning juvenile South African abalone and secondly, to test the effects of basket design on the growth ... -
Heteroscleromorph demosponge taxonomy and diversity of the Amathole region (Eastern Cape, South Africa)
(University of Western Cape, 2022)Sponges are functionally important and ubiquitous components of the global marine benthos. South Africa accounts for roughly 4% of the global marine sponge diversity, comprising 374 described species and seven varieties/forms, ... -
How do teachers and learners navigate the terrain of ecology and what are the associated conceptual understanding?
(2011)This thesis relates the teaching of ecology in schools to the requirements of the National Curriculum Statements, Grades R-9 and Grades 10-12, for Natural and Life Sciences. It examines the conceptual understanding of the ... -

Identifying and mapping invasive alien plant individuals and stands from aerial photography and satellite images in the central Hawequa conservation area
(University of the Western Cape, 2012)The Cape Floristic Region, situated at the southern tip of Africa, is one of the world’s most botanically diverse regions. The biodiversity of this region faces various types of threats, which can be divided into three ... -
Impacts and control of alien Proteaceae invasion in the Western Cape Province, South Africa
(University of the Western Cape, 2017)Research focused on ecological impacts and control of invasive alien species (IAS) is gaining attention worldwide. The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant ... -
Impacts of degradation on critically endangered Oudtshoorn Gannaveld
(2010)In the Succulent Karoo biome of South Africa vegetation degradation by overgrazing is a recognized threat to biodiversity. In the eastern Little Karoo region of the Western Cape Province, ostrich farming has degraded large ... -
Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level
(University of the Western Cape, 2007)Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the ... -
Implications of potential biome boundary shifts for small mammal assemblages in the arid zone
