- Description: This study analyses a selected cohort of black South African novelists‟ depiction of the real burning issues of the post-Apartheid South Africa. The ideas that the study is concerned with in the novel under study, are based on the aspect of theme and how it is utilised by the respective authors to address the social, economic and political issues in the post-Apartheid South Africa. The study is an investigation of the extent to which black South African novelists have depicted the aforementioned issues. The research highlights those issues that the novels under study addressed and continues by revealing how the authors depict these issues in their texts. Moreover, the study concludes that literature has a role to play in the society and recommends that it should be reliable and useful to the society. It further recommends that literature should not ignore societal issues and should be corrective in its approach. The study is comprised of six chapters: Chapter One functions as an introduction to the study. It provides information on the aims and objectives of the study, the background information on the novels under study and South African literature itself. The chapter also outlines the method and the theories, which will be used in the study. It concludes by addressing the significance of the study. Chapter Two provides a detailed analysis of the theories, which will be used in the study. This includes the Marxism and Realism theory, Afrocentric theory and the Feminist Literary theory. It also defines the concept of theme and outlines its characteristics. It discusses post-colonial literature and its development in Africa. The chapter will conclude with a disclosure of the role of theme and of the author in the African novel. Chapter Three addresses the depiction of burning issues in Mpe‟s novel “Welcome to Our Hillbrow”. It discusses the real post-colonial challenges confronting the society during the post-Apartheid South Africa. It determines whether the novel under study adequately addresses these issues. Chapter Four identifies and addresses the depiction of burning post-colonial issues in Magona‟s novel “Beauty‟s Gift”. It unveils the themes that are dealt with in the novel under study thereby linking them effectively to the current situation in the new South Africa. Chapter Five unveils the central themes in Mahala‟s Novel “When a Man Cries” and it illustrates how the author protests against the ills of post-Apartheid South Africa. Chapter Six serves as the conclusion of the study and brings out the findings and recommendations of the study. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: South Africa has seen remarkable growth in student numbers at universities since reforms were introduced with the advent of democracy in 1994. Enrolments have almost doubled in the past twenty years, yet South African Higher Education (HE) is characterised by high levels of failure and dropout, and an estimated 50 to 55% of each intake will never graduate. This is not only an indictment on HE institutions (HEIs), but also results in rising debt to the students and to society. In South Africa, student debt has increased at an alarming rate since 2012, whilst state funding has decreased. Students have advocated for education to be free. President Zuma announced in December 2017 that education for the poor would be free. It is not clear yet where the funding will come from, but it would not be from universities’ as their budgets are already thinly spread. The main aim of this study was to identify the factors contributing to students dropping out of university in their final year of study, with some modules still outstanding. 360 final year students were identified as having less than 60% of their required credits left to complete their studies, but they had not re-registered and they were thus categorised as non-completing students or dropouts. An analysis of their biographical characteristics revealed that non-completing students were more likely studying for a diploma, male, ‘black’, and did not have English as a home language. Trends were also analysed across faculties and qualification types. In addition to the quantitative description of the biographical characteristics of the non-completing students, a further qualitative exploration was undertaken.Telephonic interviews were conducted with 65 of the non-completing students using a semi-structured interview schedule. The schedule consisted of four grand tour questions and various prompts to ascertain the reasons for students not completing their qualifications. The qualitative results revealed that financial, academic, health and personal problems were the main factors in Nelson Mandela University (NMU) final year undergraduate students’ decisions not to complete their studies. Other factors identified included taking up job opportunities and struggling to balance work and studies; along with factors related to the need for more flexible modes of delivery; and a more inclusive, caring, humanising institutional culture. If the 360 students with 60% or less of their required credits outstanding had graduated at NMU, the institution would have received approximately R8.6 million in subsidy income. In addition to the R8.6 million loss in subsidy income, there would also have been a considerable loss in fee income. Of these 360 non-completing students, 27 students had just one module outstanding. Had these 27 students with just one module outstanding been able to complete their outstanding module and graduate, the institution could have earned an approximate subsidy income of R767 667. The cost of the outstanding modules of these 27 students amounted to R111 070. This shows that the university could have reaped a substantial return on investment if these students could have been assisted to graduate. Based on these findings, a number of recommendations and suggestions were made to support students with the aim to assist the university to reduce the number of non-completing students and enable as many students as possible to complete their studies and graduate. These included having procedures in place for students to be able to take up their concerns with academics and faculty administration; implementing a system to track student progress and to institute interventions as soon as possible; greater flexibility in the delivery modes of modules, with increased online and distance learning possibilities for students who had only a few modules to complete; and creating an institutional culture where students develop a sense of belonging and feel included, which enhances the chances that they will persist until they complete their studies. Limitations of the study were noted and a number of recommendations for further studies were made.

- Description: This study sought to investigate lecturer preparedness to apply a critical approach to curriculum implementation and to establish their willingness or unwillingness to engage as transformative intellectuals with their students and to apply a problem-posing education in their classrooms. The study investigated lecturers’ critical pedagogy dispositions as well as their orientations towards applying a critical approach to curriculum implementation. A comprehensive literature review was done regarding the concept critical pedagogy, its tenets and principles as well as what it entails to apply a critical approach to curriculum implementation. In particular the literature review highlighted the responsibilities of a transformative intellectual as well as the requirements of applying a problem-posing education. The study was conducted through a constructivist lens and theoretically framed by referring to specific critical pedagogy concepts. The study is located in the interpretive paradigm and a qualitative research approach was followed. In particular, an instrumental case study analysis was used as research method. The sample consisted of 20 permanently employed lecturers from the School for Initial Teacher Education in the Faculty of Education at Nelson Mandela University who volunteered to participate in an online investigation regarding their critical pedagogy dispositions as well as their orientations towards applying a critical approach to curriculum implementation. The findings of the study revealed that lecturers generally have a positive disposition towards critical pedagogy as well as towards the application of a critical approach to curriculum implementation. Despite this positive picture there were pockets of resistance towards critical pedagogy and the application of a critical approach to curriculum implementation. Finally, the study proposes a critical approach model that could be employed to enhance lecturer preparedness to apply a critical approach in their classes.

- Description: The concept of "the people" has become a key concept within the work of several Latin American theologians, Korean Minjung theologians and South African theologians. When liberation theologians use the concept of "the people" in their literature they do so with a lack of clarity, to the extent that the exact meaning of the term is obscure. In their usage of the concept "the people" liberation theologians come up with differing and at times contradictory meanings, particularly as regards the concrete and symbolic meanings of the concept. This thesis sets out to investigate the use of the concept "the people" by liberation theologians by consulting a selection from Latin American theology, Korean Minjung theology, South African liberation theology and Marxism, to detect its influence on the use of this notion. A general overview of the thesis indicates the following. The first chapter provides a detailed analysis of the concept of "the people" in the work of different liberation theologians. Chapter two considers "the people" in relation to poverty and oppression. The third chapter deals with "the people" as subjects of history. In the fourth chapter "the people" as a concept is developed in relation to belief within the Christian church. The final chapter is an evaluation. The thesis reveals that the following characteristics are central to "the people", they are poor and oppressed but are also inclusive of all those persons who identify and actively support the struggle against poverty and oppression. "The people" are subjects of their own history, finally they are Christian believers.

- Description: Bull sharks (Carcharhinus leucas) are globally distributed top predators that play an important ecological role within coastal marine communities. However, little is known about the spatial and temporal scales of their habitat use and associated ecological role. In this study, we employed passive acoustic telemetry to investigate the residency patterns and migration dynamics of 18 adult bull sharks (195–283 cm total length) tagged in southern Mozambique for a period of between 10 and 22 months. The majority of sharks (n = 16) exhibited temporally and spatially variable residency patterns interspersed with migration events. Ten individuals undertook coastal migrations that ranged between 433 and 709 km (mean = 533 km) with eight of these sharks returning to the study site.

- Description: A study was conducted in Melani rural community of Raymond Mhlaba district in Eastern Cape, with the aim of identifying types of energy sources and households energy utilization. Melani village (32°43’29” S, 27°07’35” E) is 13 km away from Alice, the closest town and its household population is about 350. The survey was conducted with 50% of the randomly chosen households using semi-structured questionnaires and some onset CTA-A hobo current transducers were installed in three households to measure electricity used for either cooking, heating or lighting. The survey shows that electricity (supplied by Eskom) is the main source of energy for cooking, lighting and heating, while paraffin and candles are also used for lighting. The data collected using the data acquisition system has also shown that each household consumes an average of 140 kWh of electricity per month. Assuming this amount of energy being used throughout the year, on average the households consume 1680 kWh of electricity per year. The research concludes that there is a need to promote sustainable energy resources and technologies such as the use of biogas digesters as an alternative source of energy since the households has on average 20 of cattle, 10 of goats, 10 sheep and 4 donkeys. The research has also shown that the economic analysis of the biogas project is financially feasible. The Net present value was high and positive showing the feasibility of the investment on the project. The payback period was implying that the project pays itself off within the service life or within a set payback limit, which must be shorter than the technical service period of 5 years. The research has further shown that the emission factor for carbon dioxide for every 1MWh of electrical energy saved is 1.07 kg and consequently a corresponding volume of avoidance water is 1.40 KL. This can be mentioned that this monthly cost saving in the electrical energy consumption can go a long way in improving the social and economic welfare of the people. More so, it also vi plays a key role in the reduction of the global warming potential and the amount of air pollutant in the atmosphere. The avoidance water also contributed greatly in reducing the total volume of water used in the cooling towers of the coal power generation plant.

The research concludes that there is a need to promote sustainable energy resources and technologies such as the use of biogas digesters as an alternative source of energy since the households has on average 20 of cattle, 10 of goats, 10 sheep and 4 donkeys. The research has also shown that the economic analysis of the biogas project is financially feasible. The Net present value was high and positive showing the feasibility of the investment on the project. The payback period was implying that the project pays itself off within the service life or within a set payback limit, which must be shorter than the technical service period of 5 years. The research has further shown that the emission factor for carbon dioxide for every 1MWh of electrical energy saved is 1.07 kg and consequently a corresponding volume of avoidance water is 1.40 KL. This can be mentioned that this monthly cost saving in the electrical energy consumption can go a long way in improving the social and economic welfare of the people. More so, it also vi plays a key role in the reduction of the global warming potential and the amount of air pollutant in the atmosphere. The avoidance water also contributed greatly in reducing the total volume of water used in the cooling towers of the coal power generation plant.

- Description: This study examined and documented the perceptions of local communities towards the socio-environmental impacts associated with illegal sand mining activities along the Umvoti River, in the KwaDukuza Local Municipality in South Africa. It was imperative to elicit the perceptions of both the local people and the government officials to understand the extent of the socio- environmental effects of illegal sand mining in the study area. To this end, a qualitative research approach was designed and used to collect the data. Data collection techniques employed included site observations and a semi-structured interview schedule with key informants. Additionally, 50 questionnaire surveys were administered to the residents of the Nsikeni and Melville communities within the study area. The results of the study revealed that illegal sand mining along the Umvoti River has contributed significantly to the degradation of grazing and farm lands, including diversion of the river and the destruction of the riparian vegetation. Evidence of water pollution, and air pollution in the form of dust, were also reported. The study observed problems in ecosystem functioning, particularly in regard to the flora and fauna, and there was extensive destruction of the aesthetic beauty of the local landscape. In addition, the study indicated that people and livestock drowned in the deep trenches that were not rehabilitated following illegal sand mining practise that was migrating along the river. Furthermore, illegal sand mining was linked with an increase in poverty and prostitution, as well as the destruction of the infrastructure in the nearby communities. Moreover, community conflicts arose from the differing perceptions on the existence of illegal sand mining in these communities. To curb illegal sand mining, the study recommends that the current legislation on the extraction of mineral commodities in South Africa should be stringently and effectively enforced. The research further recommends that community policing forums should be established and work closely with law enforcement agencies to deal with illegal sand mining activities. Accordingly, the research study recommends the elimination of the current tedious and burdensome process of obtaining amining permit. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2020

- Description: Despite many initiatives that are being implemented by the governments of different nations and the international community to minimize hunger and poverty in rural areas, several households continue to suffer from food insecurity. The World Food Programme (WFP) and the government in Zimbabwe are providing food aid to approximately 1.6 million people across the 37 districts in the country. Measures have been undertaken to counter food insecurity in Zimbabwe but to no avail. Food related public policies such as donor aid and government subsidies have also been unworkable for such a long time. In this study a comprehensive analysis of the role of decent rural employment in counteracting food insecurity will be provided. The study also seeks to assess how humanitarian work psychologists can work together with various stakeholders in society so as to curb household food insecurity. The Study population included all the households in Bindura rural district in Zimbabwe. Both quantitative and qualitative research designs were used. The researcher used cluster sampling procedure in which households were divided into groups (clusters) and a sample of the groups was selected. A random sample was then drawn from the elements within each selected group. The results confirmed that those that are not decently employed face a broad range of decent work deficits, exploitation at work and are food insecure, a finding that is similar to other countries. Thus, the researcher concluded that Decent Rural employment do have an impact on food security. Taking a look at the basic tenets of decent employment such as full time employment, a decent income, reasonable working hours and employee benefits among others, the results showed that they all impact on food security. The information obtained will be fundamental for communities at risk and dealing with the issue may help improve food insecurity situation in the country. This information will also help in formulating special measures in the form of tailor made strategies specifically made for the district and helps in doing away with what is called a one size fits all approach to food security as it pays particular attention to the households in that particular district. , Thesis (MA) -- Faculty of Management and Commerce, 2014

- Description: In South Africa, local government as represented by a number of municipalities, is at the coal-face of service delivery. As such, the effect of community displeasure with poor service delivery is usually directed at this sphere of government. To maintain and develop infrastructure such as roads and electricity, municipalities are dependent on financial grants allocated by the national government. Notably, in the main, municipalities are required to maximise their own sources of revenue in order to render the requisite operational services/activities. Inevitably, municipal budgets are usually not sufficient to meet the unlimited service delivery obligations required by the local communities. The Nelson Mandela Bay Municipality (NMBM) is not immune to these interconnected revenue generation and service delivery priorities. The primary objective of the study is to establish an effective CRM framework that may enhance revenue collection at the NMBM. More specifically, the study investigates the nature of Customer Relationship Management (CRM) at the NMBM, factors that are responsible for ineffective CRM at the NMBM, the impacts of ineffective CRM on revenue collection at the municipality and the ways in which a CRM framework suitable to improve revenue collection at the NMBM can be established. Purposive sampling was used to select a sample of 130 respondents from a population of 420 employees in the Revenue Management and Customer Care Sub-directorate of the municipality. In view of the primary objective of the study, participants were drawn from relevant divisions such as, customer care, debtor management, rates and valuations, billing coordination and receipting. Of 130 questionnaires distributed, only 121 usable questionnaires were returned. This translates to a response rate of 93%. The empirical results reveal that there is a positive relationship between CRM and revenue management. In addition to this, the empirical results show that there is a positive relationship between customer satisfaction, customer engagement, customer value, customer experience, service standards and CRM. Furthermore, the findings of the study show that more needs to be done, as very little has been achieved by the NMBM in the context of implementing measures to enhance CRM. In this regard, the study provides managerial and future research recommendations.

- Description: It is imperative that society works together with government and industry to find solutions in solving the problem of the high utilisation of natural resources in the built environment. Natural resources are not infinite, and the increasing population are compounding the problem. The high level of unemployment in South Africa could be increased dramatically if the old skills in the industry become redundant due to new technology and there are not enough skills to apply to these technologies. This study set out to investigate the extent of the readiness of South Africa for the Smart built environment towards 2035 with an aim to provide valuable information for decision making to the government, policy makers, academic and training institutions and business leaders. South Africa boasts about the achievements of the four major municipalities namely, Cape Town, Johannesburg, Tshwane and eThekwini in terms of their commitment towards the aim for net zero carbon emissions of newly built buildings by 2050. The commitment for sustainable solutions in all sectors is echoed by the Minister of Environmental affairs, as part of the Paris agreement. South Africa does not lack the ability to plan for eventualities. This is evident by the myriad of strategies and policies that can be found all over the government information sharing outlets. The South African government is failing in implementing these policies and strategies that have been around for more than a decade. A lack of execution, lack of transparency as well as a lack of accountability is a hindrance to South Africa’s general growth path. The realisation of the preferred future rest on the acceptance, by all South Africans, that technological advancement is inevitable, and that a joint and inclusive effort should be made to prepare for such a future. South Africa has the ability and appetite to change the future for the better. Two fundamental areas of improvement are to create a united South Africa where people are held accountable for their actions. The unisons should transcend across the various South African government departments but must also include industry, entrepreneurs and the public to create a future where technology is embraced, and innovation encouraged, instead of waiting for technology to dictate a specific future.

- Description: Post-colonial states in Africa continue to pursue nation-building and socio-economic development. This process is taking place with the sustained support of global agencies in terms of development cooperation, assistance and aid. Insofar as an endogenous development path which speaks to national priorities can be formulated and implemented by post-colonial states, their relationship with these agencies raises serious questions about such a path if the relationship entails dependence and indeed subordination of post-colonial states. This raises important questions about state autonomy under post-colonial conditions and the possibility of autonomy being compromised. In this light, the thesis examines European Union budget support to Mozambique and, in particular, the relationship between EU budget support and Mozambique state autonomy in pursuing national development. This is particularly pertinent given the massive dependence of the Mozambican state on foreign funding (notably EU funding) with specific regard to the national budget. Despite the broad claims existing in the prevailing literature that nation-state autonomy is seriously undermined in and through the international development system, the thesis argues against reductionist arguments that simply posit post-colonial states as mere instruments of global forces. This system, including European Union budget support, does indeed set the conditions of existence for post-colonial states such as Mozambique. But autonomy is necessarily relative and is subject to different forms and degrees. Ultimately, it is through empirical investigation that the specific form and degree of autonomy can be pinpointed and understood. The thesis contributes to this endeavour and suggests that the relationship between European budget support and Mozambican state autonomy is more complex and tension-riddled than the prevailing literature would seem to suggest.

- Description: Infection control is an essential cornerstone of clinical care at all healthcare settings. The changing pattern of infections emphasises the need for all healthcare workers, including radiographers, to implement and strictly adhere to standard infection control precautions (SICP) that will protect both patients and healthcare workers from healthcare associated infections (HAIs). However, implementing SICP can be difficult, especially if radiographers do not have adequate knowledge, and skilled practices, in infection control. As a practicing radiographer and a health educator, the researcher observed that there were discrepancies regarding implementation of SICP by radiographers in Malawi. No study has been conducted to explore and describe the knowledge and practices of radiographers regarding infection control in radiology departments in Malawi. There are also no infection control guidelines. These gaps led to this study being conducted. The aim of the study was to explore, and describe, knowledge and practices of radiographers regarding infection control in radiology departments in government referral hospitals in Malawi in order to develop a draft guideline for infection control to facilitate sound knowledge and practices of radiographers regarding infection control in these departments. The study took place in four government referral hospitals and followed a quantitative, exploratory, and descriptive design that was contextual in nature. The study was conducted in two phases. In the first one a self-administered questionnaire was used to explore and describe the knowledge and practices of radiographers regarding infection control in government referral hospitals in Malawi. The second one included the development of a draft guideline for infection control in order to facilitate sound knowledge and practices of radiographers regarding infection control in government referral hospitals in Malawi. In phase one, the research population consisted of 80 permanently employed radiographers. A census sampling method was used to select 62 respondents. The data were collected by means of a self-administered questionnaire that was developed based on a literature review. Some questions were adapted from an existing questionnaire. The questionnaire consisted of questions and statements. It had four parts: demographic information (Part A), knowledge regarding infection control (Part B), practices regarding infection control (Part C), and additional relevant information (Part D). Descriptive and inferential statistics, with the help of a statistician, were used to analyse the data. The results of the study revealed that radiographers had average knowledge and practice in terms of infection control. The results revealed a significant association between age and knowledge (P<0.05). In phase two, a draft guideline was developed. The guideline’s content is based on 20 gaps identified in phase one of the study, as well as literature. The draft guideline consists of seven sets of recommendations: hand hygiene, personal hygiene, personal protective equipment (PPE), safe handling of sharps and sharp containers, decontamination and cleaning, housekeeping, and routine infection control practices. Reliability and validity were ensured. Ethical considerations were considered throughout the study. Respect for persons, beneficence and justice were adhered to. The study is the first in the field of radiography in Malawi. Results of this study should contribute to the body of knowledge of radiography practice. The results are to be used to inform practicing radiographers, heads of departments, the Ministry of Health and Population, and other health practitioners about the current practices and knowledge of radiographers in government referral hospitals in Malawi. The draft guideline should facilitate sound knowledge and practices regarding infection control among practicing radiographers in these departments. Recommendations include further development and implementation of the draft guideline, and radiography education and development of further research on infection control in the radiography profession, specifically in the African context.

- Description: Tuberculosis (TB) is a multi-organ infection caused by rod-shaped acid-fast Mycobacterium tuberculosis. The World Health Organization (WHO) ranks TB among the top 10 fatal infections and the leading the cause of death from a single infection. In 2017, TB was responsible for an estimated 1.3 million deaths among both the HIV negative and positive populations worldwide (WHO, 2018). Approximately 23% (roughly 1.7 billion) of the world’s population is estimated to have latent TB with a high risk of reverting to active TB infection. In 2017, an estimated 558,000 people developed drug resistant TB worldwide with 82% of the cases being multi-drug resistant TB (WHO, 2018). South Africa is ranked among the 30 high TB burdened countries with a TB incidence of 322,000 cases in 2017 accounting for 3% of the world’s TB cases. TB is curable and is clinically managed through a combination of intensive and continuation phases of first-line drugs (isoniazid, rifampicin, ethambutol, and pyrazinamide). Second-line drugs which include fluoroquinolones, injectable aminoglycoside and injectable polypeptides are used in cases of first line drug resistance. The third-line drugs include amoxicillin, clofazimine, linezolid and imipenem. These have variable but unproven efficacy to TB and are the last resort in cases of total drug resistance (Jilani et al., 2019). TB drug resistance to first-line drugs especially isoniazid in M. tuberculosis has been attributed to single nucleotide polymorphisms (SNPs) in the catalase peroxidase enzyme (katG), a protein important in the activation of the pro-drug isoniazid. The SNPs especially at position 315 of the katG enzyme are believed to reduce the sensitivity of the M. tuberculosis to isoniazid while still maintaining the enzyme’s catalytic activity - a mechanism not completely understood. KatG protein is important for protecting the bacteria from hydro peroxides and hydroxyl radicals present in an aerobic environment. This study focused on understanding the mechanism of isoniazid drug resistance in M. tuberculosis as a result of high confidence mutations in the katG through modelling the enzyme with its respective variants, performing MD simulations to explore the protein behaviour, calculating the dynamic residue network analysis (DRN) of the variants in respect to the wild type katG and finally performing alanine scanning. From the MD simulations, it was observed that the high confidence mutations i.e. S140R, S140N, G279D, G285D, S315T, S315I, S315R, S315N, G316D, S457I and G593D were not only reducing the backbone flexibility of the protein but also reducing the protein’s conformational variation and space. All the variant protein structures were observed to be more compact compared to the wild type. Residue fluctuation results indicated reduced residue flexibility across all variants in the loop region (position 26-110) responsible for katG dimerization. In addition, mutation S315T is believed to reduce the size of the active site access channel in the protein. From the DRN data, residues in the interface region between the N and C-terminal domains were observed to gain importance in the variants irrespective of the mutation location indicating an allosteric effect of the mutations on the interface region. Alanine scanning results established that residue Leucine at position 48 was not only important in the protein communication but also a destabilizing residue across all the variants. The study not only demonstrated change in the protein behaviour but also showed allosteric effect of the mutations in the katG protein.

- Description: Tuberculosis (TB) is a multi-organ infection caused by rod-shaped acid-fast Mycobacterium tuberculosis. The World Health Organization (WHO) ranks TB among the top 10 fatal infections and the leading the cause of death from a single infection. In 2017, TB was responsible for an estimated 1.3 million deaths among both the HIV negative and positive populations worldwide (WHO, 2018). Approximately 23% (roughly 1.7 billion) of the world’s population is estimated to have latent TB with a high risk of reverting to active TB infection. In 2017, an estimated 558,000 people developed drug resistant TB worldwide with 82% of the cases being multi-drug resistant TB (WHO, 2018). South Africa is ranked among the 30 high TB burdened countries with a TB incidence of 322,000 cases in 2017 accounting for 3% of the world’s TB cases.

- Description: This study considers the dynamical interaction of two predatory carnivores (Lions (Panthera leo) and Spotted Hyaenas (Crocuta crocuta)) and three of their common prey (Buffalo (Syncerus caffer), Warthog (Phacochoerus africanus) and Kudu (Tragelaphus strepsiceros)). The dependence on spatial structure of species’ interaction stimulated the author to formulate reaction-diffusion models to explain the dynamics of predator-prey relationships in ecology. These models were used to predict and explain the effect of threshold populations, predator additional food and prey refuge on the general species’ dynamics. Vital parameters that model additional food to predators, prey refuge and population thresholds were given due attention in the analyses. The stability of a predator-prey model for an ecosystem faced with a prey out-flux which is analogous to and modelled as an Allee effect was investigated. The results highlight the bounds for the conversion efficiency of prey biomass to predator biomass (fertility gain) for which stability of the three species ecosystem model can be attained. Global stability analysis results showed that the prey (warthog) population density should exceed the sum of its carrying capacity and threshold value minus its equilibrium value i.e., W >(Kw + $) −W . This result shows that the warthog’s equilibrium population density is bounded above by population thresholds, i.e., W < (Kw+$). Besides showing the occurrence under parameter space of the so-called paradox of enrichment, early indicators of chaos can also be deduced. In addition, numerical results revealed stable oscillatory behaviour and stable spirals of the species as predator fertility rate, mortality rate and prey threshold were varied. The stabilising effect of prey refuge due to variations in predator fertility and proportion of prey in the refuge was studied. Formulation and analysis of a robust mathematical model for two predators having an overlapping dietary niche were also done. The Beddington-DeAngelis functional and numerical responses which are relevant in addressing the Principle of Competitive Exclusion as species interact were incorporated in the model. The stabilizing effect of additional food in relation to the relative diffusivity D, and wave number k, was investigated. Stability, dissipativity, permanence, persistence and periodicity of the model were studied using the routine and limit cycle perturbation methods. The periodic solutions (b 1 and b 3), which influence the dispersal rate (') of the interacting species, have been shown to be controlled by the wave number. For stability, and in order to overcome predator natural mortality, the nutritional value of predator additional food has been shown to be of high quality that can enhance predator fertility gain. The threshold relationships between various ecosystem parameters and the carrying capacity of the game park for the prey species were also deduced to ensure ecosystem persistence. Besides revealing irregular periodic travelling wave behaviour due to predator interference, numerical results also show oscillatory temporal dynamics resulting from additional food supplements combined with high predation rates.
