Abstract:

Austroglanis gilli and A. barnardi are endemic to the Clanwilliam-Olifants System in the Western Cape, South Africa. The populations of each of these species are considered to be threatened by various anthropogenic activities, which include inappropriate agricultural practice and impacts of alien invasive fish species. The purpose of this thesis was to assess the life-history of these two endangered species in order to contribute to understanding their biology. Such information is vital for the development of strategies for their conservation. Marginal zone and marginal increment analyses from

The taxonomic position and biogeography of redfins in relation to other barbs are uncertain. Enzyme electrophoresis was employed to assess genetic differentiation within and among certain Barbus and Pseudobarbus taxa. Fourteen enzymes were routinely recorded from muscle tissue extracts, yielding a differential number of active loci. The latter is due to different plo

Abstract:

The outlook for Nile crocodiles in the Olifants River does not look optimistic. Since the increase in capacity of the Loskop and Flag Boshielo Dams, the crocodile population was left with no basking or nesting sites and has declined over the past 30 years. Shortly after the Massingire Dam in Moçambique filled to full capacity an estimated 160 crocodiles died in the Olifants River Gorge, a couple of kilometres upstream from the dam. The Olifants River is acknowledged by many experts as one of the most polluted rivers in South Africa and acid mine drainage, industrial pollution and untreated sew

Furthermore, the impact of invasion is determined by the geographical range, abundance and the per-capita or per-biomass effect of the invader.

The Matjes River Rock Shelter, in the Plettenberg Bay region of South Africa, has a large collection of archaeological cranial remains representing 8,000 years of occupation. Forty-three adult crania from the Matjes River collection are studied here, many which have not previously been published. These crania are compared through multivariate analysis with other dated crania from Fish Hoek, Cape Flats, Elands Bay, Port Elizabeth and Kenkelbosch, and with archaeological crania from five ecological biomes, Forest, Fynbos, Nama Karoo, Savanna, and Succulent Karoo biomes in southern Africa.

Abstract:

The spatial and temporal patterns in selected components of the ichthyofauna and piscivorous avifauna in the small temporarily open/closed Riet River Estuary located on the eastern seaboard of southern Africa was investigated monthly over the period August 2005 to July 2006. The ichthyofauna within the littoral zone of the estuary was sampled using a 5 m seine net (8 stations) while a 30 m seine net (4 stations) was employed to sample the fish in the channel. Bird counts were made along repeat transects along the length of the estuary. Total ichthyofaunal abundances and biomass ranged between

Abstract:

The grasslands of South Africa are the foundation of commercial and subsistence agriculture yet they are being degraded at an alanning rate. The coastal grasslands of the Eastern Cape are no exception and they suffer added pressure of coastal resort development because of their proximity to an attractive coastline. In order to determine the degree of conservation necessary for any area it is essential to know what species occur there in order to determine if protection from habitat destruction is required. Four aims were defined for this studv. The initial aim was a phytogeographical classific

Abstract:

The main aim of the project is to investigate the feasibility of artificial recharge of the Bushmans River Mouth Aquifer in the Eastern Cape. The suggested method of recharge is through natural infiltration through a series of wetlands in the back dune area. The proposed site was the Klipfontein Vlei which is located just north of the Bushmans River Mouth. Artificial recharge is defined as augmenting the natural movement of surface water into underground formations by some method of construction, the spreading of water, or by artificially changing natural conditions. A variety of methods have

Bibliography: leaves 74-77.<br>The increase in urbanisation and the use of metal compounds and products domestically and in industry has resulted in the production of by-products and wastes, which needs to be evaluated in the urban environment. The discharge of some of these wastes into urban rivers should be evaluated to determine the potential effects, for example, toxicity and mobility. The effects may, in part, be determined by the chemical states in which these wastes manifest themselves, and by the chemical associations they have.

>Magister Scientiae - MSc<br>The present study investigated the application of a multi-method approach to determine groundwater-surface water (GW-SW) interactions to quantify and characterize the quality of water resources in a fractured rock aquifer system in upper catchment of the Berg River (G10A). Demonstrating methods for improved understanding of groundwater and surface water interactions is important for informing development of strategies that ensure effective utilization and management of water resources. Applying a single method to inform innovative strategies for water resources has

The aquifer of the study area occupies an escarpment and low lying limestone plain, and exhibits a Vaal River type karst. The four dolomitic formations present fall into two distinct aquifer forming types; chert poor units and chert rich units. The chert poor units of the Oaktree and Lyttelton Formations were deposited in a subtidal environment and were probably dolomi tised in a migrating schizohaline environment during basin subsidence and shoreline trangression. The chert rich units of the Monte Christo and Eccles Formations were deposited in the shallow subtidal to supratidal zones and the

The purpose of this study was to evaluate the level of service quality within South African sport tourism and in the tourism industry in general, by focusing on a specific case study, the Berg River Canoe Marathon. The study discussed the importance of service quality within sport tourism, while the methods and instruments applic

A metre wide column was excavated through six metres of shell-rich deposits at the junction of two cuttings made in the 1920s and 1950s and known as the "Apex". A small section was cut into the upper layers in the entrance area. A suite of radiocarbon dates shows the deposits to be between 6300 and 10 600 years old with a possible hiatus in deposition

The writer has attempted through policy intervention to achieve this goal. A policy for a greenbelt was compiled to allow for limited development along the Crocodile River Greenbelt area. The first step was to compile a policy for the Crocodile River Greenbelt area, and to contextualise the legislative requirements to compile such a
