- Description: The prediction of, and changes in, medullated fibre levels during early stage processing of mohair, from greasy to top, have been studied. Commercial lots, representative of the South African and Basuto mohair clips, covering a wide range of properties, with respect to objectionable medullated (kemp type) fibres, length and fibre diameter, were sampled for testing at three different processing stages, viz. greasy, preparatory gilled sliver, and top. All samples were tested with an Optical Fibre Diameter Analyser (OFDA100) for medullated- and fibre diameter related properties. Various statistical analyses were conducted to determine the most significant correlations and best prediction of changes in medullated fibre levels, during processing. As expected, the medullated fibre levels of the Basuto lots were much higher than those of the Cape lots. Moreover, the inclusion or exclusion of flat fibres, in combination with other medullated fibres, resulted in significant differences in the outcome of some of the statistical analysis. It was found that flat fibre levels were highly correlated with the standard deviation of fibre diameter at all processing stages, and also, the greasy standard deviation of fibre diameter was the best predictor of flat fibre levels in the top. Further, the percentage reduction in flat fibres, from greasy to preparatory gilled sliver, was more than double that of the reduction in flat fibres from preparatory gilled sliver to top. Similarly, the percentage reduction in objectionable medullated (including flat) fibres, from greasy to preparatory gilled sliver, was about 1.7 times more than that of the reduction from preparatory gilled sliver to top.

- Description: Prostitution or Sex work has been a crime in the country for a number of decades. In earlier years sex work was not explicitly crminalised and the government relied on various laws to regulate and deal with sex work. With the passage of time sex work was formally regulated and dealt with specifically as a criminal offence by legislation. Those legislative measures still exist to ensure that sex work remains a crime in South Africa. Courts have on a number of occasion been tasked to consider the status of sex workers in the context of the human rights provided for by the Constitution of the Republic (both the interim and the final). In the two seminal cases of S v Jordan and others and Kylie v CCMA the courts approached the status of sex workers on the basis that even sex workers are entitled to the human rights enshrined in the Constitution. The Constitutional Court in Jordan, however refused to decriminalise sex work for those purposes holding that it is for the legislature to decide the issue of decriminalisation. Various interest groups have lobbied for the decriminalisation of sex work in order to give meaning to Constitutional rights of sex workers. The criminalisation of sex work appears to be a case of the state legislating morality and interfering with private individual matters. With a bad history of state interference in private affairs of individuals this practise should be guarded against in the Constitutional dispensation. Criminal law as such should have no application in private instances that cause no harm to any other person or state interests. It appears that the continued criminalisation of sex work is increasingly appearing to be without proper justification and as such it is recommended that the country adopts the New Zealand model of decriminalisation. This will ensure that the rights of sex workers are duly respected.

- Description: Product development using quality by design is a proactive and risk-based approach that shifts the manufacturing process from empirical to science-based. Risk assessment was performed to identify and analyse risk areas for the manufacture of captopril pellets. Twelve experimental runs were performed using a Plackett-Burman screening design. Pareto plots revealed the effect of formulation and process variables on the responses monitored and facilitated the identification of the most critical parameters for optimization of the formulation. A response surface methodology approach in conjunction with a central composite design was used to optimize the Eudragit® RL 30D (15-30 ml), microcrystalline cellulose (20-40 % w/w), sodium starch glycolate (2-5 % w/w) and spheronizer speed (650-1050 rpm).

- Description: The applicability of a quality by design framework for the development of a sensitive, simple and selective, stability-indicating reversed-phase high-performance liquid chromatography analytical method for the analysis of captopril was investigated. Design of experiments using a central composite design approach was used for method development. Twenty experimental runs were performed with acetonitrile content ranging between 28 and 36 % v/v, pH from 2.8 to 3.6 and temperature between 22° and 32°. The experimental data obtained was used to derive a quadratic model for the retention time of captopril. The optimized method produced sharp peaks with good resolution (>2) for captopril and the internal standard with retention times of 3.1 and 6.2 min, respectively. The experimental data revealed that acetonitrile content in the mobile phase and pH are significant factors that affect the retention time and resolution of captopril. Normal probability plots revealed that the residual and predicted data fall approximately on a straight line, indicating that the experimental error for these studies was evenly distributed suggesting that the model could be used to navigate the design space. This approach is useful to expedite method development and optimization activities in analytical laboratories.

- Description: South Africa is faced with high incidents of sexual violence and abuse, affecting a large part of the population either directly or indirectly.Previous studies have shown that a contact with victims of violent crime may cause psychological symptoms of Secondary traumatic Stress (STS) in police officers. Despite this knowledge, there appears to be a lack of studies that focus specifically on police detective officers (PDOs) in South Africa. Aim: This study aimed to investigate the relationship between exposure to traumatic complainants and STS among PDOs in the SAPS-FCS unit. Findings: The results have shown that most of the PDOs were exposed to traumatised complainants as they often conduct investigation, testify in court, escort complainants for biopsychosocial services and collect evidence from both complainants and perpetrators. The study further found that most PDOs were experiencing a degree of STS symptoms. Additionally, no significant statistical relationship was found between exposure to traumatised complainants and STS. Nonetheless, there is a statistically significant relationship between type of crimes and STS among PDOs in the SAPS-FCS unit. This study sheds light on how the PDOs are indirectly affected by the crimes experienced by complainants’, such as indecent assault and child molestation. This research can be used as a platform for the development of various interventions with police officials exposed to or affected by indirectly trauma. Future research should investigate other pivotal risks and protective factors such as environmental factors and personal factors that may have impacted on the development of STS in the PDOs.

To contribute to the ongoing attempts to reduce poverty, it is necessary to have an understanding as to why people remain poor in an affluent world and what can be done to address the causes of poverty. Unless a global culture of ethics and value alignment is pursued for the reduction of poverty, there will be devastating effects for the future Underwriting lasting escapes from chronic poverty demands more investment in education, employment and human development potentials and in the related infrastructure that permits people to enhance their living standards while developing their resilience to handle setbacks and the effects of climate change.ffects include, for example, disaster-risk management, global healthcare and social cohesion.

- Description: In many parts of the world, excess growth of Eichhornia crassipes (Pontederiaceae) poses a serious threat to aquatic environments. In Cameroon, where manual clearing is still undertaken, little is known about fungal diversity associated with the plant, or its potential for biological control. Surveys of the Wouri River Basin in the Littoral Region of Cameroon were conducted during a rainy season (May–October 2014) and a dry season (November 2015–April 2016) at various sites, to identify fungi associated with water hyacinth. Fungi were isolated and identified from symptomatic plant parts collected. In the rainy season, 130 fungal isolates belonging to 12 genera were identified morphologically, whereas 299 isolates belonging to 23 genera were identified during the dry season. With the exception of Fusarium oxysporum and Phytophthora sp., the genera represented new records for Cameroon, and Chaetomium strumarium, Colletotrichum gloesporioides, C. acutatum, C. dematium, Curvularia pallescens and Pytomyces chartarum were considered new host records for E. crassipes in Africa. Isolates of Acremonium zonatum, Chaetomium strumarium, Alternaria eichhorniae, Phytophthora sp. and Rhizoctonia sp. showed the highest frequency of occurrence on E. crassipes in the Wouri River Basin and, given their record as plant pathogens, could be potentially useful in the development of mycoherbicides for this weed in Cameroon.

- Description: Since publication of the first record of Eichhornia crassipes in Cameroon in 1997, the weed has become highly invasive in the Wouri River Basin. Between June and September 2014, a socio-economic survey using participatory and qualitative methods was undertaken in the riparian villages of the Wouri River Basin to assess the perception of respondents to the presence of water hyacinth. The survey revealed that water hyacinth was a significant threat to activities along the river, which included fishing, sand extraction and river transportation. The presence of water hyacinth mats reduced catch rates of several common fish species, river transportation by 75%, and significantly reduced the income for sand extraction. Cameroon employs manual clearing of water hyacinth; however, respondents indicated they would consider other control methods, provided they do not have any negative impacts.

- Description: This study explores people’s insights of personal branding by means of social networking. The continuously increasing competitive marketplace is creating a situation where people find it difficult to stand out from their peers. Personal branding affords the opportunity for people to be noticeable in competitive environments. This study used a qualitative research method employing two phases. The semi-structured personal interviews using a semi-structured interview schedule was conducted in the first phase, while the content analysis using criterion schedules analysing participants’ Facebook and LinkedIn social networks was done in phase two. The results of phase one of the study revealed that the majority of participants did not know what a personal brand was, but they believed they possessed a personal brand. Phase two of the study revealed that only a few participants had a coherently perceived personal brand and presented personal brands on both Facebook and LinkedIn. Phase two of the study also revealed that the majority of participants more prominently presented the skills necessary for the future work environment on Facebook rather than LinkedIn. In conclusion, the findings showed that most participants did not actively manage their personal brands across multiple social networking sites. They also did not effectively present the necessary skills for the future work environment on their social networking profiles.

- Description: Men who are victims of intimate partner violence seem to be largely ignored in research and literature. This in part is linked to the perception of men as perpetrators, rather than as victims of violence. While intimate partner violence has been studied extensively across the world, through a number of disciplines, there appears to be a glaring gap in the literature. Men who are victims of intimate partner violence may experience the emotional and psychological consequences of violence differently, given the factors influencing the role of men in society. The resulting shame, guilt and even rejection may be factors explaining why these cases of violence are underreported. This research used a systematic review methodology and data was collected through online databases. Significant thematic findings identified included 1) the impact of stigma, 2) misrepresentation of the article content focus, and 3) the lack of awareness surrounding the act of male abuse within intimate partner relationships. The study findings suggested that male victims of intimate partner violence are likely to experience the psychological and emotional experiences that follow the experience. Further insight was given regarding the need to develop interventions that take into account the required social, psychological and emotional needs of men in violent intimate partner relationships.

Men who are victims of intimate partner violence may experience the emotional and psychological consequences of violence differently, given the factors influencing the role of men in society. The resulting shame, guilt and even rejection may be factors explaining why these cases of violence are underreported. This research used a systematic review methodology and data was collected through online databases. Significant thematic findings identified included 1) the impact of stigma, 2) misrepresentation of the article content focus, and 3) the lack of awareness surrounding the act of male abuse within intimate partner relationships. The study findings suggested that male victims of intimate partner violence are likely to experience the psychological and emotional experiences that follow the experience. Further insight was given regarding the need to develop interventions that take into account the required social, psychological and emotional needs of men in violent intimate partner relationships.

- Description: .M. Coetzee’s The Lives of Animals (1999) is a literary representation of, and intervention into, human-animal relations. It is an experimental literary destabilisation of the generic boundaries that underlie the systematic (mis)representation and (mis)treatment of nonhuman animals, specifically their mass commodification in contemporary societies. The text provides a critique and negotiation of anthropocentric reason and its ramifications for nonhuman animals. This study focuses on how Coetzee’s narrative problematises dominant discourses through questioning their authority and offering alternatives to anthropocentric conceptions of the animal that are based upon reason-centred and dualistic thought. The duality of human versus animal is explored alongside other dualities deconstructed in the text, such as fiction versus nonfiction, and philosophy versus literature. Coetzee’s representation of these constructs and their interconnectedness is investigated, specifically with regards to positively developing human-animal relations. Through exploring what Coetzee calls the ‘sympathetic imagination’, his alternative contribution to the field of human-animal relations will be considered. This study focuses on the space for re-imagination that Coetzee has provided with The Lives of Animals. It highlights the role literature can and ought to play in this re-imagination, and why this re-imagination is necessary for the development of human-animal relations. Posthumanism will be used as a theoretical lens throughout, as it appears to resonate closely with Coetzee’s project. Both the form and the content of the text will be analysed, highlighting their interconnected significance in Coetzee’s project and the continued relevance of interventions such as this.

- Description: The South African state’s ideological commitment to a participatory approach to managing water resources and delivering services in a way that includes all stakeholders warrants critical analysis.Realising this ideological commitment has proved challenging, due largely to the complex historical, political, social, and environmental context of integrated water resource management (IWRM) in South Africa. The overarching aim of this study was to explore and expand the learning of civil societyparticipating in water governance processes at a local government scale. To address this aim a single, in-depth, four-year case study into civil society participation in water governance in the Makana Local Municipality in the Eastern Cape Province of South Africa was conducted between 2014 and 2018. The case study comprised two research phases. Both phases of the research were conducted using an adaptive transdisciplinary and participatory action research approach underpinned by General Complexity Theory. Located at the research-practice interface, the study sought to be transformative and advance both scientific research and societal goals. Qualitative research methods and inductive and deductive modes of inference were used to collect and analyse the data respectively. In the first phase of the study, a Communities of Practice theoretical framing was adopted to investigate the emergence, practice and learning of a civil society organisation (CSO), Water for Dignity (WfD), in response to household water service delivery issues in the municipality. This phase served to build an understanding of factors that enabled and constrained the practice of WfD in addressing local water service issues, and of their role as social learning agents in building water-related knowledge in their community. As participation with the first civil society organisation fragmented, the opportunity arose for local government, the National Department of Water and Sanitation and civil society to co-engage. This opened up the second phase of the research during which the role of a multi-stakeholder platform, the Makana Water Forum (MWF), in enabling democratic water governance was investigated. The MWF was South Africa’s first catchment management forum with an integrated water service and water resource management agenda. In this phase, the study drew on interventionist methodology, Change Laboratory, from Cultural Historical Activity Theory (CHAT) to 1) describe the historical development, composition and shared purpose of the MWF multi-activity system constellation; and to 2) guide participants through seven learning actions (expansive learning cycle) to identify, analyse, model and implement remedial actions to problematic aspects (contradictions) of the MWF practice. Participants of the Change Laboratory workshops built their individual and collective transformative agency (deliberate actions to transform a problematic situation) as they navigated the expansive learning process. The development of this agency was identified through a micro-analysis of agentive talk. The two phases served to advance the exploration of civil society participation from informal participation to address water issues, to formal participation in water governance processes at a local government scale. Findings from the first phase of the research revealed that dedicated and sustained support of partners with distributed expertise and the highly motivated core members of WfD enabled the practice and emergence of the civil society organisation. However, factors such as poor internal leadership, power dynamics between supporting partners, socio-economic constraints and a deeply embedded lack of agency were found to be key constraining factors to WfD’s practice. Findings revealed that learning at WfD team level occurred in four ways, through learning as belonging, learning as doing, learning as experiencing and learning as becoming. The WfD CSO was able to catalyse social learning related to personal water rights; and best practices for improving water quality and water conservation in their wider community of practice. Social learning was fostered mainly through structured citizen engagements offered by WfD. The research provides evidence that civil society organisations can play an important role in bridging water-related knowledge gaps and can foster active citizenship in South African communities. However, despite significant inputs of support and resources through the engaged transdisciplinary research process, the practice and learning outcomes of WfD had a marginal transformative impact on improving the citizen’s every-day water service experiences. Findings from the second phase of the study revealed the MWF to resemble a multi-activity system constellation with a multiple, partially overlapping. interests related to the management of water. The establishment, function and contradictions constraining the function of the MWF were influenced by past cycles of participatory water governance-related activity and practice at national and local scales. Through the Change Laboratory process, 25 contradictions were identified that appeared to constrain the ability of the MWF to enable inclusive and meaningful participatory water governance. Through a process of expansive learning, participants sought to overcome three sets of contradictions grouped as Problem Themes: lack of clear focus of the MWF; representation, representivity and nonattendance; and the MWF relationship with the Makana Local Municipality. Remedial actions modelled and those enacted have improved aspects of the function of the MWF (such as diversified modes of engagement and a more focussed agenda) but have only resulted in incremental shifts towards enabling improved participatory practice, most markedly in building a collaborative relationship and trust between the MWF members, municipal and government officials. The microanalysis of agentive talk revealed seven different expressions of transformative agency. Constraining socio-economic and political conditions and the limited capacity of the coordinating committee of the MWF hindered the development of transformative agency to the extent to which concrete actions were implemented. Findings further revealed that contextualising a Change Laboratory process within the adaptive cycle of a complex social-ecological system, and the particular opportunity context the system presents, could inform the enactment of agency and its potential impact on the transformation of the system. The intervention with the MWF was too short a process to clearly observe the effects of transformative actions on the sustainability of the Makana Local Municipality water system. However, long-chain transformative agency through the development of one-on-one engagements, learning journeys and a reflexive component to the MWF engagements could support transformative pathways to sustainability in the municipality and water management system. The study contributes in-depth insight into the key role of learning as a catalyst in transformative processes. Learning improves the collaborative and adaptive capacity of people, and therefore, water management institutions, to manage explicitly for the complexity inherent in “complex” socialecological systems. It provides empirical evidence as to what enables and constrains “real” participation and learning in grass-roots water governance processes in the context of a shifting national drive towards a more adaptive and developmental Integrated Water Resource Management approach. It further provides methodological contributions to 1) the application of the Change Laboratory method with multi-activity system constellations in developing world contexts and 2) value and limitations of extended and engaged transdisciplinary research. Lastly, it provides practical recommendations to the establishment and sustainable function of both community-based CSOs and multi-stakeholder platforms engaging in water governance processes.

- Description: The ideologies and structures of the apartheid state have received extensive academic attention, but the legacies of the militarisation of white South African men – a group that exists at a unique intersection of apartheid privilege and exploitation – have not been sufficiently addressed. Even as beneficiaries of apartheid, white men were militarised through structures of coercion and the mobilisation of identity constructions that resulted in the widespread submission to conscription and support for apartheid militarism. This thesis explores the relationship between those militarised identities and the historical processes of apartheid through a consideration of a broad range of white SADF veteran narratives from the Missing Voices Oral History Project archive. This consideration of the role of identity mobilisation in apartheid can shed light on the effect of historical processes of militarisation on white men in South Africa, as well as address the persistence of values and behaviours that may present barriers to the social transformation of South Africa towards a true constitutional democracy. The thesis explores identity in SADF veteran narratives through the application of social constructionism in order to determine the effect of coercive structures and identity mobilisation on individuals, and to gauge the persistence militarised identities after the social and political structures underpinning them had become defunct. The identity content of the narratives is contextualised in relation to structures of coercion employed by the apartheid state and the SADF alongside a consideration of the effect of political transition on veterans. The legacy of the historical environment and the impact of political transition on SADF veterans’ constructed identities is investigated in relation to these veterans’ own visions of their roles in post-apartheid South Africa. Therefore, this thesis endeavours to contribute to the expansion of the field of historical and identity study by considering the construction and renegotiation of military identities that maintained, benefited from, and were exploited by the apartheid state.

- Description: The main aim of this thesis is to establish whether affirmative action is justified and to consider the limitations imposed thereon. Regard had to be made to the past position, as affirmative action emanated from the apartheid era. This paper provides for an extensive discussion of what affirmative action entails and compares the past position of unfair discrimination towards the current position of affirmative action. It is important to have regard to the Constitution, legislation and case law relating to the application of affirmative action. Within this paper reference to the Constitution, LRA, EEA, case law, academic writings and journal articles is made in order to evaluate on what basis affirmative action is founded, justified and limited. The approach used in terms of substantive equality based on the Van Heerden1 and Harksen v Lane2 judgments. Provision is made as to whom affirmative action applies to. The process of implementation of affirmative action is visited with a view to give guidance on how affirmative action should be implemented, what the short comings are in the public sector with the implementation process and to provide guidelines to achieve a positive and effective affirmative action in South Africa Because certain people regard affirmative action as reverse discrimination, the contrary had to be analysed by way of legislation and authority from case law in order to provide for the correct position. It would become apparent from this paper that affirmative action does not only apply to designated employees, after the Van Heerden Judgment the courts have developed their approach in a number of authorities for example in Alexandre v Provincial administration of the Western Cape Department of Health3. India makes use of affirmative action that is in some instances similar to the South African approach. For a distinct reason I have chosen a comparison between India and South Africa. The reason is that, each individual’s personal circumstances that are to benefit from affirmative action have to be assessed before affirmative action applies to them. Further that I do not agree with the fact that a group as a whole should benefit, therefore recommendations have been made.

- Description: We investigated the presence of medium-sized and large mammals utilizing by-catch data from a camera trapping survey in the Mangwe District in South West Zimbabwe, an unprotected commercial livestock farming area which is impacted by human encroachment, poaching and trophy hunting. The camera trapping survey was carried out from 23 October to 5 December 2009, covered an area of 200 km2 and was initially intended to estimate the population density of leopards (Panthera pardus). The study area was split into two contiguous subsections, with each section sampled for a total of 20 days using 20 cameras. Camera trap photographs were identified to species level, then compared to a list of species thought to occur in the area according to available literature, as well as sightings from professional hunters and local landowners.

- Description: Teamwork and the ability to work effectively in a team is a critical skill in a technologically complex workplace where no individual can possess all the knowledge and skills. MBA programmes, therefore, require students to work in collaborative learning groups in order to not only share their knowledge and skills, but also to develop the needed team-based competencies. However, collaborative learning groups are prone to many pitfalls that could result in intra-group conflict and inefficiencies such as social loafing, where the group performance is less than the sum of the output of the individual members when working alone. Team development interventions (TDI) aim to improve team-based competencies of a team. One type of TDI that is often employed is social team building. It typically consists of a one-day extra-mural excursion involving some non-work-related tasks performed by teams to improve interpersonal relationships. The MBA groups are pre-allocated at the start of the academic programme and team building interventions are therefore needed to facilitate group formation. The main research question in this study deals with the effectiveness of these social team building TDI’s to promote group formation. The literature of teams and the factors that influence team effectivity were reviewed. Input-Process-Output models relate the factors that drive team performance. Three team viability measures critical to a teams’ performance were identified namely, group cohesion, group communication and goal-setting. There is strong empirical evidence that these factors contribute positively to the performance of the team. The influence of team building interventions on each of these factors were discussed. There is empirical evidence for the impact of team building interventions on these affective outcomes. However, empirical evidence for the link to objective performance measures is still lacking

- Description: The main research problem addressed in this study is that South African cities are not effectively integrating and utilising available, and rapidly emerging smart city data sources for planning and management. To this end, it was proposed that a predictive model, that assimilates data from traditionally isolated management silos, could be developed for prediction and simulation at the system-of-systems level. As proof of concept, the study focused on only one aspect of smart cities, namely crime management. Subsequently, the main objective of this study was to develop and evaluate a predictive model for crime management in smart cities that effectively integrated data from traditionally isolated management silos. The Design Science Research process was followed to develop and evaluate a prototype model. The practical contributions of this study was the development of a prototype model for integrated decision-making in smart cities, and the associated guidelines for the implementation of the developed modelling approach within the South African IDP context. Theoretically, this work contributed towards the development of a modelling paradigm for effective integrated decision-making in smart cities. This work also contributed towards developing strategic-level predictive policing tools aimed at proactively meeting community needs, and contributed to the body of knowledge regarding complex systems modelling.

- Description: Digital participatory mapping improves accessibility to spatial information and the way in which knowledge is co-constructed and landscapes co-managed with impoverished communities. However, many unintended consequences for social and epistemic justice may be exacerbated in developing country contexts. Two South African case studies incorporating Direct-to-Digital participatory mapping in marginalized communities to inform land-use decision-making, and the ethical challenges of adopting this method are discussed. Understanding the past and present context of the site and the power dynamics at play is critical to develop trust and manage expectations among research participants. When employing unfamiliar technology, disparate literacy levels and language barriers create challenges for ensuring participants understand the risks of their involvement and recognize their rights. The logistics of using this approach in remote areas with poor infrastructure and deciding how best to leave the participants with the maps they have co-produced in an accessible format present further challenges. Overcoming these can however offer opportunity for redressing past injustices and empowering marginalized communities with a voice in decisions that affect their livelihoods.

- Description: The study examines four curriculum documents with regards to curriculum facets, further interrogated through indicators for certain facets in order to ascertain whether the documents could be considered to be educative. Comparison is made with selected resources internationally. Observed episodes in four mathematics classes are interrogated with regards to teacher facets and concomitant indicators, to assess whether the tenets proposed in the written curriculum are translated into practice in the classrooms. The four Grade 3 teachers are interviewed about their views on the curriculum, their views on teaching and their views on their own agency in teaching mathematics. The teachers’ complete selected examples from a Mathematics Knowledge for Training (MKT) questionnaire and are engaged in conversations about iii their beliefs about mathematics and their confidence in both doing and teaching mathematics. The study identifies that the current CAPS curriculum documents focus on mathematical content almost exclusively and give minimal guidance concerning pedagogical content knowledge. The agency of teachers is not addressed. The study suggests a three-dimensional model of curriculum design that encompasses new educative curriculum materials; guidance on innovative teacher practices and direction towards new beliefs in teachers which could build agency and confidence. The concern that this study uncovers is that although the school and teachers were specifically chosen to minimise linguistic and social detractors, the intended curriculum does not appear to have been universally translated into

Fishes of Southern African estuaries: from species to systems

- Description: South Africa, despite its relatively small size, is often called “a world in one country”. This phrase arises mainly from the range of oceanographic and climatic features; geological and geomorphological attributes, the diversity of human cultures, languages, races and religions; the mix of developed and developing economies; the wide range in political opinion and parties; the vast array of mineral resources; and finally, what biologists find most interesting of all, the richness of the indigenous flora and fauna. Although southern African aquatic scientists cannot boast an equivalent of the Cape Floral Kingdom, the stretch of coast between northern Namibia and southern Mozambique has a particularly rich marine biota, accounting for almost 15% of all the coastal marine species known world-wide. The richness of the ichthyofauna is due to a number of factors, including the variety of habitats around the subcontinent, ranging from coral reefs, kelp beds, sheltered bays, sandy beaches, exposed rocky shores, coastal lakes to estuaries. In addition, southern Africa is the meeting place of three great oceans and is thus the recipient of species from each of these separate faunas. In comparison to land vertebrates, the world’s fish fauna is by no means well-known, either taxonomically or with regard to the biology of the component species. Apart from the very large number of fish species (estimated to be approximately 40 000), and the difficulties posed by the medium in which they live, there are other reasons for the above state of affairs. An obvious and universal reason is the shortage of funding available for taxonomic, biological and ecological studies, with increasing emphasis being placed on aquaculture, mariculture and fisheries related work. This situation is unlikely to improve and many research institutions around the world are operating on shrinking rather than expanding budgets. The onus of responsibility to disseminate information on the world’s fish faunas therefore rests squarely on the shoulders of those who are fortunate enough to be employed in the fascinating field of ichthyology. This book, which is a major revision and expansion of an earlier monograph (Whitfield 1998), is an attempt to synthesize the available information on fishes associated with southern African estuaries and to highlight the importance of conserving these systems for both fishes and people of the region. Limited reference is made to international estuarine fish research due to space constraints and readers are referred to global ichthyological reviews in this regard. The estuaries of southern Africa (defined as south of 26°S latitude for the purposes of this book) are highly diverse, both in terms of form and functioning. They range from the clear Kosi Estuary entering the coral rich subtropical Indian Ocean waters on the east coast, to the turbid Orange River flowing into the cool upwelled waters of the Atlantic Ocean on the west coast. The estuaries of the subcontinent are fed by catchments with a wide variety of climatic and geological characteristics. For example, the cool-temperate west coast is characterized by good winter rains and relatively dry summers, whereas on the subtropical east coast the opposite rainfall pattern prevails. While most south-western Cape estuaries are fed by rivers with low suspended sediment levels, those of KwaZulu-Natal normally carry high silt loads during the rainy season. Between Mossel Bay and St Francis Bay, rainfall patterns show no distinct seasonal peak and relatively acidic waters with low nutrient levels enter a variety of estuarine types along this section of the coast. The Eastern Cape is a region of transition between the subtropical and warm-temperate biogeographic provinces, and is prone to both droughts and floods occurring during any season of the year. The southern African estuarine environment is an unpredictable and often harsh habitat to occupy, yet each year millions of larval and juvenile fishes enter and thrive in these systems. The fish species that utilize estuaries as nursery areas exhibit great diversity in size, body form, salinity tolerance, diet, habitat preference and breeding behaviour. There is also a complete gradation in terms of the dependence that each species has on the estuarine environment. These and many other issues relating to the biology and ecology of estuary-associated fish species in southern Africa are explored in the chapters to follow. It is my sincere wish that our improved knowledge of these species and their environmental requirements will contribute to the wise management and conservation of these valuable ecosystems. , 2022 Edition
