The northern hardwood forest type is a critical habitat component for the endangered Carolina northern flying squirrel (CNFS; Glaucomys sabrinus coloratus) for denning sites and corridor habitats between montane conifer patches where the squirrel forages. This study examined terrain data, and patterns of occurrence for the northern hardwood forest type in the recovery areas of CNFS in western North Carolina and southwestern Virginia with the purpose of creating a more robust predictive model of this forest type for spatial delineation. I recorded overstory species composition as well as terrain variables at 338 points throughout the study area in order to quantitatively define the northern hardwood forest type. These data were used in conjunction with digital terrain data for creation of the predictive model. Terrain variables we examined to attempt to differentiate northern hardwoods from other forest types included elevation, aspect, slope gradient, curvature, and landform index. I used an information-theoretic approach to assess six models based on existing literature and a global model.  My results indicate that on a regional, multi-state scale, latitude, elevation, aspect, and landform index (LFI) of an area are significant predictors of the presence of the northern hardwood forest type in the southern Appalachians.  My model consisting of Elevation + LFI was the best approximating model based on lowest AICc score.  Our Elevation + LFI model correctly predicted northern hardwood presence at 78.2% of our sample points observed to be northern hardwoods. I then used this model to create a predictive map of the distribution of the northern hardwood forest type in CNFS recovery areas. / Master of Science

Magister Artium - MA / The issue of personhood has long been of concern to many philosophers. The primary concern has been about determining the necessary and sufficient conditions for an entity to be a person at a particular point in time. The most common answer in Western terms is that to be a person at a time is to have certain special mental properties such as psychological connectedness. On the other hand, others argue that we can only ever understand the ascription of mental characteristics as part of a necessarily joint set of physically instantiated properties. Most recent contributions to the topic have however cast doubt on these earlier attempts to understand personhood solely in terms of bodily and psychological features. Not only do they suggest a model of personhood that is individualistic, they also fail to make reference to communal and social elements. In particular, many non-Western, specifically African, cultures foreground these communal and social aspects. This is true of the Akan, Yoruba and Igbo cultures. As Kwasi Wiredu and Kwame Gyekye; Dismas Masolo; Segun Gbadegesin; and Ifeanyi Menkiti have shown respectively. However, there is a lack of comparable philosophical inquiry in the Southern African context. The primary aim of this study is to critically explore the metaphysical, cultural, linguistic and normative resources of the Zulu people in understanding what it means to be a person. The approach is predominantly conceptual and analytic, but it also draws on some empirical data with a view to extending the results of the literature-based study. Not only does this extend the field of cultural inquiry to personhood, it also opens up new opportunities to tackle old problems in the debate, including the question of what should be the proper relationship between the individual and the community. Specifically, I argue that rather than focus attention on the priority of the individual or community in relation to each other, consideration of the notion of personhood in Zulu culture reveals that notwithstanding significant communal constraints forms of agency are available to individuals. http://

The giant bullfrog, Pyxicephalus adspersus, is a large, explosive-breeding anuran from southern Africa, which spends most of the year buried in a state of torpor. In South Africa this species is considered to be Near-Threatened by habitat loss and other factors, especially in the densely human populated Gauteng Province. The aim of this thesis was to obtain essential outstanding information about the ecology of P. adspersus to contribute towards improved conservation management of this species. A model was used to predict the geographic range of P. adspersus in southern Africa, and recent land cover data were used to determine the amount of suitable habitat remaining for this species in Gauteng. As a step towards identifying P. adspersus conservation management units, genetic structure and gene flow for populations from 23 localities in Gauteng and seven additional localities in the north-eastern interior of South Africa was quantified using 708 base pairs of the mitochondrial gene cytochrome b. To investigate the unpredictable activity and unknown spatial habitat requirements of P. adspersus, a population’s spawning and non-breeding activity was monitored, and the movements of 70 adult frogs were radio- or spool-tracked during five summers at a site in Diepsloot, Gauteng. Using skeletohronology, the age distribution of breeding P. adspersus at this and two other peri-urban sites near Johannesburg, Gauteng, was examined. Bioclimatic conditions were predicted to be suitable for P. adspersus in the temperate to semi-arid interior, but not the low-lying eastern subtropical and arid western sides of southern Africa. Limited genetic data suggested that P. adspersus was common in the north-eastern interior of South Africa, and that populations in the Free State Province represent an evolutionary significant unit of this species. In central Gauteng, where P. adspersus may have declined by > 90%, populations < 20 km apart exhibited significant genetic differentiation, possibly as a result of genetic drift. At Diepsloot, both annual numbers of spawning events and numbers of spawning males were positively correlated with rainfall, although other meteorological variables also affected the activity of P. adspersus. Radio- or spool-tracked frogs showed high fidelity to their breeding site and burrows, which were situated up to 1 km away from the water. Male P. adspersus probably live 20 years in the wild, but at some peri-urban breeding sites adult life expectancy and body size may be declining. The geographic range of P. adspersus was predicted to be slightly smaller than that reported by other authors, and deserves phylogeographic validation. The main conservation priority for P. adspersus in South Africa should be the protection of terrestrial habitat for adult foraging and aestivation around, and for juvenile dispersal and gene flow between, breeding sites. In Gauteng, the conservation of a P. adspersus metapopulation is critical, and could most likely be achieved in the northern region of this province. Populations in the Free State Province deserve improved protection given their reported genetic uniqueness. At local spatial scales specific threats (e.g. pollution) should be ameliorated, and long-term monitoring should be implemented to detect real population trends. / Thesis (PhD)--University of Pretoria, 2012. / Zoology and Entomology / Unrestricted

MENVSC (Climatology) / Department of Geography and Geo-Information Sciences / Subtropical anticyclones locate and modulate weather and climate over subtropical belts for both the Northern and Southern Hemispheres. This study investigates the spatio-temporal variability of the Mascarene High over the South Indian Ocean on (anomalous) weather and climate over southern Africa at intraseasonal, seasonal, interannual, multidecadal and event time-scales. The Mascarene High is located 25-35°S, 40-110°E, playing a vital role in day-to-day weather and climate patterns conditions over southern Africa. Spatio-temporal characteristics of the Mascarene High investigated in this study span the period 1985-2014 and 2071-2100, using NCEP-NCAR reanalysis datasets for present-day climate observations and the Conformal-Cubic Atmospheric Model (CCAM) for future projections. The Mascarene High is analysed using mean sea level pressure (MSLP) extracted from ECMWF ERA-interim monthly reanalysis data. The Mascarene High is also subjected to Principal Components Analysis, depicting eastern displacements of the weather system to be dominant for weather and climate fluctuations over southern Africa. The Mascarene High migrates south (north) during austral summer (winter) and is centred over the eastern Indian Ocean in summer in connection with the Indian Ocean Subtropical Dipole. Event scale analysis is also employed for investigating Mascarene High blocking and induced anomalous weather. Mascarene High blocking leads to anomalous rainfall events over southern Africa associated with tropical cyclones, cut-off lows and cloud bands. There is also a vital geographical variability of the Mascarene High development, distribution and movement in the South Indian Ocean at the different time-scales. Projections of the Mascarene High indicate a shift in mean location as a result of future expansion and intensification. This projected expansion and intensification is expected to shift tropical cyclone trajectories equatorward, with the baroclinic structure of cold fronts expected to shift poleward affecting changes in the weather and climate of southern Africa. This finding is important as it projects changes in weather and climate conditions over southern Africa in a changing climate due to increased greenhouse gas emissions.

Unemployment among youth within the Southern African Development Community (SADC) region is one of the major factors that has contributed to migratory movements. Today many youths are leaving their home countries within the region, in search of employment opportunities in stronger economies like that of South Africa. However, the local unemployment rates hinder their chances of employment. This qualitative study explored the livelihood strategies of unemployed black female migrant youth living in Cape Town, South Africa. The study interviewed twenty unemployed black female migrant youth between the ages of 25 and 34 to understand their experiences and perceptions of a) factors or conditions that forced them to immigrate to Cape Town, b) challenges they encountered in trying to secure employment, and vulnerabilities experienced, and c) the livelihood strategies they employed and available social service support. The findings reveal that unemployed black female migrant youth have immigrated to Cape Town for various reasons including political instability, social influences, poor economic conditions, and social factors such as marriage and poverty in their home countries. When they arrive in Cape Town, they face many obstacles in securing employment because of either their nationality or documentation status. They are also vulnerable due to lack of basic needs, living in overcrowded homes, and being in informal settlements where they build temporary shelters. To overcome the challenges they face, they engage in different livelihood strategies such as accessing free government clinics or hospitals for their healthcare. They are dependent on their spouses for support and engage in part-time employment. Besides, they have had limited information about any government or non-governmental organisations that provide support for unemployed black female migrant youth. The need for well-established social networks for unemployed black female migrants, where they can be received and assisted in integrating into society through legitimate channels, is relevant. There need to be centres that offer free English-language training for migrants who are not conversant in English. Established non-governmental organisations or government agencies need to provide facilities that could assist undocumented immigrants who have prolonged their stay in Cape Town. There is also a need to establish support centres that specifically target unemployed black female immigrants. The South African government should enforce sensitization and educate the public and stakeholders about the legitimacy of asylum-seeker permits issued to immigrants. If implemented in conjunction with policy measures, this could increase black female immigrant youth's ability to secure employment. The enforcement of the development of entrepreneurial skills programmes, which specifically vi target unemployed black female youth migrants in Cape Town, is another potentially beneficial strategy.

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol) / The tribe Anthemideae is a large tribe of the family Asteraceae comprising 111 genera and 1 800 species distributed in Africa, Europe, Asia, and the Northern temperate region, with southern Africa as one of its main centers of diversity, together with Central Asia and the Mediterranean. Ongoing studies have focused on analysing relationships among the southern African subtribes of Anthemideae and the most recent classification recognised fourteen subtribes in which there is a clear biogeographical gradient, with the six southern African subtribes comprising the earliest diverging lineages. The present study focuses on two of these southern African-centred lineages (viz. subtribes Athanasiinae and Phymasperminae). Previous phylogenetic studies of the tribe were based on nuclear nrDNA ITS and plastid cpDNA ndhF sequence data and included only a single representative from each of the genera within the subtribes Athanasiinae and Phymasperminae. / 2024

The purpose of this study is to get some concrete evidence that group principles can be applied to church groups in an effective manner. The more immediate purpose is to improve the relations in the individual classes so that they will have a feeling of belongingness, relatedness, or close affiliation. It is the purpose of this experiment to help these individuals find the fulfillment of their personal needs that can be supplied in the Sunday School class.

Bibliography: p. 206-228. / Understanding a widespread motif in San rock art - a human figure depicted in frontal perspective with distinctive bodily characteristics - is the aim of this study. A concentration of these figures in north eastern Zimbabwe was first described by researchers in the 1930s and subsequently, when one researcher, Elizabeth Goodall, described them as 'mythic women'. Markedly similar figures in the South African art have received little attention. On the basis of fieldwork in the KwaZulu-Natal Drakensberg, the south western Cape (South Africa) and Zimbabwe, and an extensive literature survey, a spectrum of these figures is described. In order to further understanding of the motif, existing interpretive methods and the traditions which inform them are examined, with a view to outlining a number of areas in need of attention. It is argued that analysis of rock art remains dependent on a range of dualistic notions which may be linked to retained structuralist ideas. It is suggested that the dominant model in rock art research, in which the rock art is seen as essentially shamanistic, perpetuates distinctions between mind and body, myth and ritual, and sacred and profane, while in its search for general truths concerning the rock art, and its central focus on iconography, the model retains traces of linguistic structuralism. It is proposed that the 'mythic woman' motif, with its gendered and sexual characteristics, is not well accounted for by reference to southern San ritual and religious practice alone. Drawing on contemporary theories concerning temporality and embodiment, it is argued that the motif is better understood in relation to recurrent themes of death and regeneration in San mythology and oral narratives, with shamanistic practice enacting related themes. The motif may be seen as representing San history in terms of culturally specific temporal schemes arising from San experience of the world. The 'ethnographic method', by means of which San accounts are used to illuminate features of the art, is reassessed and extended. Hermeneutic theories are drawn upon in order to address questions regarding the way in which ethnographies and art may be mutually illuminating, and to account for the inevitability of multiple interpretations arising from the situated process of reading or viewing. Prominent themes, images and devices in San myth and oral narrative are discussed in an attempt to move beyond a narrowly iconography-centred approach and in order to account for devices and stylistic features of San arts which are evident in both verbal and visual media. Implications of the research for investigating an archaeology of gender, and the writing of San history, are discussed.

The Sabie River Basalt Formation is a group of tholeiitic basaltic rocks erupted ca 190 Ma ago in the eastern zone of the Karoo Igneous Province of southern Africa. It is traceable over a distance of 700 km from Zululand, northwards along the Lebombo monocline into the Transvaal and south-east Zimbabwe. An abrupt compositional change in this formation occurs about halfway down its length in the vicinity of the Sabie and Komati Rivers: basalts to the north are known to be enriched in certain incompatible elements relative to basalts in the south, which are comparable in geochemistry to most basaltic rocks in the southern part of the Karoo Igneous Province. New data obtained in this work include 134 major and trace element whole-rock analyses, some 400 analyses of constituent minerals, 38 ⁸⁷Sr/⁸⁶Sr ratio determinations, 19 ¹⁴³Nd/¹⁴⁴Nd ratio determinations, 16 common Pb determinations and 12 oxygen isotope analyses. The "normal" (N) and "enriched" basaltic rocks are distinguished by differences in the concentrations of Ti, P, Zr, Nb, Y, La, Ce and Nd (high field strength elements). Broadly these differences are substantiated by K, Rb, Ba and Sr, but with much more overlap. The "enriched" group of basaltic rocks has been further subdivided into a low-Fe "enriched" (LFE) group and a high-Fe "enriched" group (HFE). The LFE-group basalts, which predominate at the base of the stratigraphic sections, are considered to be equivalent to basalts occurring in the N. Lebombo. In the central Lebombo N-group basalts predominate in the mid- and upper portions of the sections and HFE-group basalt occurs near the top of each section. Interbedding of all basalt groups occurs in the Sabie River section at the northern end of the study area, while the N- and HFE-group basalts are interbedded in the Crocodile and Komati River sections further to the south. The decrease in LFE-group basalt abundance southwards is accompanied by an increase in N-group basalt abundance. HFE-group basalts appear to be unique to the central Lebombo area of the Karoo Igneous Province and are volumetrically less significant than N- or LFE-group basalts. Petrogenetic models involving closed-system fractional crystallization; coupled assimilation (of granitic crust) fractional crystallization; replenished, tapped and fractionated magma chambers and partial melting are examined. Granitic crustal contamination appears to have been significant only in some samples of the N group where assimilation of granitic material has proceeded in a bulk fashion described by an AFC model. RTF models are dynamically more realistic than closed-system fractional crystallization models and explain increases in incompatible elements with decreasing MgO in the LFE and HFE groups. Variations in the N group, however, require varying degrees of partial melting of a N-type source to be explained fully. RTF models may explain the absence of any stratigraphic correlations of element abundances in the three groups. The HFE group may be related to an uncontaminated N-type parent composition by a combination of continued fractional crystallization from an N-group parent composition and varying degrees of partial melting of an N-type source. The only petrogenetic process by which the N and LFE groups may be related is different degrees of partial melting. However, this demands a source composition which has no resemblance on trace element and isotopic grounds, to observed mantle xenolith compositions. The preferred model is one in which the LFE group is derived from old sub-cratonic mantle similar to garnet-bearing "cold" peridotite xenoliths and the N group from a source similar in composition to estimates of primitive mantle. The existence of two types of mantle derived continental flood basalt magmas occurs in other Mesozoic basalt provinces in "southern" Gondwanaland (e.g. Kirwanveggan of Antarctica, Etendeka of Namibia and the Parana Basin of South America). It is suggested that there is a geographical association of LFE-type basalts with Archaean crust (or Archaean crust re-worked in low temperature - high pressure events) and N-type basalts with post-Archaean crust (or Archaean crust re-worked in high temperature - low pressure events). This model suggests the derivation of the LFE group, from old sub-cratonic lithospheric mantle relatively enriched in incompatible elements and the N group being derived from more recently accreted and less enriched lithospheric mantle underlying younger crustal terraines.

In recent times, the texts of Leviticus 18:22 and 20:13, has attracted the attention of Old Testament scholars, clergy and the laity alike. In my view, such an attention has been inspired by the readers’ quest to the possible light which the text can shed on the subject of homosexuality. The latter topic is one of the burning issues raised in present day South Africa. It thus comes as no surprise, that interpreting texts such as Leviticus18:22 and 20:13 becomes pertinent in our context. This research aims at coming up with a constructive dialogue between the Methodist Church of Southern Africa (hereafter referred to as MCSA)’s readings of this text, scholars’ interpretation of the same and the Xhosas’ reception of homosexuality in the Republic of South Africa. Through the use of methodologies such as the Literary, Textual, Canon, Composition and Redaction Criticism, as well as Socio-Scientific Criticism, Leviticus 18:22 and 20:13, will be brought to bear with its MCSA’s readings and Xhosas’ readings with a view to making a necessary contribution to African biblical hermeneutics. / Dissertation (MA(Theol))--University of Pretoria, 2010. / Old Testament Studies / unrestricted
