  • Description: The Wilderness lakes system represents a segmented barrier lagoon and comprises three interconnected lakes; Rondevlei, Langvlei and Eilandvlei. The latter is further linked by the Serpentine channel to the Touw river and Wilderness lagoon. The role of these channels, as well as a sluice in the Serpentine, in structuring certain aspects of the ecology of the system was investigated. An analysis of the salt budget of the lakes suggests that the Serpentine dampens tidaI processes to such an extent that they play only a minor role in the overall budget. Furthermore, the channel between Eilandvlei and Langvlei prevents any tidal salt input to the upper lakes. Their estuarine environments are however maintained by salt inputs which occur when the mouth is closed. This unusual phenemenon means that the sluice may have a minimal effect on the salt budget of the system because it is only closed when the mouth of the lagoon is open. Environmental conditions in each of the lakes, the Touw river and Wilderness lagoon were compared in terms of their physico-chemical characteristics and submerged macrophyte communities. A principal components analysis suggests that the physico-chemical environment of each lake is similar. The Touw river however has a very different environment, whilst that of Wilderness lagoon has some similarities to both the lakes and the river. During the study macrophyte communities recovered from a major recession which occurred between 1979 and 1981 . Biomasses in excess of 1000g m⁻² were recorded in both Langvlei and Eilandvlei. In the latter however, macrophyte growth was less prolific than in the former, as some areas of the littoral supported no growth at all. Macrophyte encroachment in the channels is a major factor inhibiting water flow between the lakes. This encroachment is most severe in the Eilandvlei/Langvlei channel where macrophytes covered 80% of the channel's area.The dominant fish fauna throughout the system is composed of a marine/estuarine migratory component. In the lakes the Mugilidae and Sparidae are the most common families, whilst in the lagoon and Touw river predators such as Lichia amia and Argyrosomus hololepidotus also commonly occur. Eilandvlei serves as the initial nursery area for most migratory species. An estimated 52000 fish migrated up the Serpentine towards Eilandvlei during February 1984 . Most fish do not penetrate as far as Langvlei, and this can be related to macrophyte encroachment in the Eilandvlei/Langvlei channel. However, it is argued that should this channel be dredged and the macrophytes removed, the nursery potential of the system would not be greatly enhanced . This is because environmental heterogeneity, in association with an abundance of food in Eilandvlei, make this lake the most attractive nursery area to juvenile marine/estuarine fish.

  • Description: From introduction: In the sixth book of The Faerie Qveene, the reader is presented with a vision of the Graces and their attendants dancing on Mount Acidale to the piping of a simple shepherd. Spenser identifies this favoured musician as Colin Clout and then goes on to pose a seemingly inconsequential rhetorical question. "Who knowes not Colin Cloute?” he asks. The note of confident pride which can be discerned in the query clearly reveals Spenser's peculiar interest in one of his most intriguing creations. It is almost impossible to read a representative selection of Spenser's poetical works without noticing the hauntingly frequent appearances of his "Southerne shepheardes boye". Colin appears or is named in no fewer than six of Spenser's poems.

  • Description: The Glen Grey Act was promulgated in August 1894. The main provisions of the Act were for the survey into individual allotments of land held tribally and for a system of local self-government. Described by its originator, C.J. Rhodes, as a 'Bill for Africa, it was first applied to the district of Glen Grey and subsequently extended (in a piece-meal fashion) to a number of districts in the Transkei. The Act was introduced at a crucial stage in South Africa's history. During this period the country stood poised on the threshhold of a significant and far-reaching transformation. The South Africa of 'old', predominantly agricultural and rural was giving way to a 'new' South Africa, modern and industrial. At the centre of this development was the mineral discoveries of the 1860s and 1880s. The period of colonial conquest had also virtually been completed. Most of the hitherto independent African chiefdoms had either been broken up or were under European control. The most urgent problem which now faced the new rulers was devising a policy to govern the millions of black people over whom they had assumed responsibility. Of crucial concern was the creation of working class to minister to the needs of the developing economy. This task was made all the more difficult by the divisions which existed among the ruling groups at the time. To all intents and purposes the country was made up of essentially four independent and autonomous regions. Although the economic changes which were taking place would hasten the unification of the country, until that happened it was well-nigh impossible for a uniform 'native policy' to take shape. The inevitable consequence was the emergence of a number of regional responses to what was essentially a country-wide issue. As the unification of South Africa drew closer however these different regional responses began to vie with each other for supremacy at a national level. The Glen Grey policy then was the response of the Cape to the changes which were taking place in the country. As such, it drew much of its inspiration from the traditions which had developed in the Cape Colony. Its initiators did not however view it as only a regional policy. For them it had applicability to the whole country. It was therefore to be expected that they would attempt to 'sell' their policy to the rest of the country. In the end however it won few adherents outside of the Cape Colony and when Union became an established fact it bowed out to a policy favoured largely by the northern provinces. To be sure the Glen Grey system did linger on for a while in those districts where it had first been applied but it would not be long before it was to fall into official disapproval. While the Glen Grey Act was ushered in with much fanfare and vaunted expectations, its demise was silent and ignominous. The grandiose course which it had charted for the taking-in-hand of the 'native question' came to naught, as did the profound and far-reaching changes which it was believed the policy would inaugurate. The origins of this policy, its implementation and actual working, and the reasons why in the end it foundered and was abandoned will be the main themes of this thesis.

  • Description: The Pied Starling is restricted to South Africa, Lesotho and Swaziland, but within this region it occupies a variety of habitats. Its modern distribution is certainly influenced by its association with man. However, a comparison with other vertebrate species, and with patterns of plant distribution, suggests that its geographical distribution has been determined primarily by its evolutionary history. A hypothesis for the origin of this species leads to several predictions concerning biogeography in southern Africa.

The ecology of Cactoblastis cactorum (Berg) (Lepidoptera : phycitidae) in relation to its effectiveness as a biological control agent of prickly pear and jointed cactus in South Africa

  • Description: The successful biological control of the shrub-like prickly pear Opuntia stricta Haworth in Australia by cactoblastis cactorum (Berg) was not repeated when C. cactorum, derived from the Australian population, was released in South Africa in the 1930's against the tree prickly pear Opuntia ficus-indica (L.) Miller. Resistance of the woody portions of o. ficus-indica to attack by C. cactorum was regarded as the main reason for the poor performance of C. cactorum in South Africa. C. cactorum also oviposits and feeds on Opuntia aurantiaca Lindley, which is currently South Africa's most important weed and which is also considered to be partly resistant to attack by C. cactorum. This study had three main objectives: (i) to compare the ecology and effectiveness of C. cactorum as a biological control agent on O. ficusindica and O. aurantiaca; (ii) to reassess why C. cactorum has not been as effective a biological control agent in South Africa as it has been in Australia; and (iii) to evaluate whether inundative release or the importation of new biotypes of C. cactorum from South America (where it is indigenous) might be feasible methods of improving its effectiveness as a biological control agent of O. aurantiaca in South Africa. All field work was undertaken at a site near Grahamstown in South Africa. The ecology and effectiveness of C. cactorum on O. ficus-indica and O. aurantiaca was assessed in terms of its oviposition behaviour, survival and feeding on these host plants. The proportion of C. cactorum eggs laid on O. ficus-indica and O. aurantiaca was similar and was influenced by the size, conspicuousness and condition of the host plant as well as by the proximity of the host plant to moth emergence sites. Factors affecting oviposition site selection on the plant are also considered. Life tables, compiled for a summer and a winter generation, showed that the survival of C. cactorum was greater on O. ficus-indica than on O. aurantiaca, mainly because higher egg predation by ants occurred on the latter host plant species. During the period of study, the population size of C. cactorum was reduced by a number of mortality factors, of which egg predation and the effects of low temperatures on fecundity were the most important. Although there was evidence of a partial, positive response by predatory ants to C. cactorum egg densities on plants, the extent of egg predation was also affected by other factors, particularly seasonal effects. C. cactorum destroyed a greater percentage of cladodes on O. ficu-indica than on O. aurantiaca, but even on O. ficus-indica it was unable to contain the growth of plants within the study area. C. cactorum larvae rarely killed the woody rooted cladodes of O. ficus-indica and O. aurantiaca and consequently whole plants were not often destroyed. The detrimental effects of host plant resistance, natural enemies and climate on the effectiveness of C. cactorum as a biological control agent all appear to be greater in South Africa than in most of the regions occupied by C. cactorum in Australia. A field experiment conducted at the study site showed that inundative release methods for improving the effectiveness of C. cactorum on O. aurantiaca are not feasible. The importation of biotypes of C. cactorum from South America that might be better suited for destroying O. aurantiaca infestations in South Africa, is also not a viable option. Results of a survey of a 218 ha area that is regarded as being heavily infested with O. aurantiaca, illustrate how this cactus species has been overrated as a weed problem. It is argued that the present strategy for O. aurantiaca control in South Africa is not based on sound economic or ecological criteria.

  • Description: In order to determine which seaweeds were unable to survive in the stressed area and how far the effect of the effluent extended along the coast, various methods were applied and carried out over a two-year period between November 1982 and November 1984. Three major long-term studies took place. The first study was to determine the presence or absence of the seaweeds throughout (1) the entire study area and then (2) in areas broken up into sections with known distances from the outfalls. The second method involved statistical evaluations using point intersect methods and photography to produce information to determine species density, diversity, evenness, and to provide the information required to work with a number of ecological equations in the future. The third method incorporated a long-term survey on cleared plots in various sectors of the study area. The recolonization of the plots was recorded over a thirty-week period. (par. 1.1, p. 6-7)

  • Description: The publication of a new phase of research on the fishes of the Okavango drainage starts with this account which gives the valid names and broad distribution patterns of all species known from the system. Eighty species and subspecies are recognised, of which at least two (Parakneria fortuita Penrith; Serranochromis gracilis Greenwood) are endemic. Notes on early collections, synonymy, taxonomic status and distribution are given. New synonyms are recognized under Aplocheilichthys hutereaui (A. schalleri), Aplocheilichthys johnstoni (Haplochilus carlislei) and Ctenopoma multispinis (Ctenopoma machadoi) respectively. Recently published taxonomic changes are incorporated including two genera (Mesobola and Afromastacembelus), a species Serranochromis (Sargochromis) gracilis and the re-allocated Amphilius uranoscopus. The Zambezian Hemichromis species is re-identified as H. elongatus. A number of unresolved taxonomic problems are pointed out and certain dubious records are excluded from the checklist. The Okavango has a diverse fish fauna with tropical affinities. Many fish species are poorly studied. Man-induced threats to the continued natural functioning of this complex and dynamic system, especially large-scale water abstraction, overgrazing, deforestation and biocide spraying to eliminate tsetse fly, make it imperative that studies on the nature and role of the fishes are continued. , Rhodes University Libraries (Digitisation)
