- Description: Bereavement is something that we experience in one way or another. It involves many steps from one culture to the other. Many scholars have documented the role of social media tools in bereavement processes. In this study, I look at the challenges and opportunities offered by Fa-cebook during bereavement, especially in a community that is still tradi-tional and has yet to fully comprehend the importance of social media, particularly in matters considered sacred. The study used interviews with residents from Taung to collect data. Thematic analysis was used to analyze the collected data from the interviews. The study findings indicate some challenges associated with bereavement on Facebook: emotional shock, lack of sensitivity, misinformation, and cultural dilution. There are also opportunities: fast news sharing, ongoing emotional support, and sharing of memories. The study argues that the findings should expand our understanding and knowledge of bereavement in some African cultures and use social media tools to complement and not destroy African beliefs and practices.

- Description: Temporary wetland ecosystems are common in arid and semi‐arid envi-ronments, and are inhabited by diverse invertebrate communities. Little is known about the dynamics of genetic connectivity in the geograph-ically scattered populations of these wetland specialists. The current study investigated the spatial genetic structure and dispersal history of a recently described calanoid copepod, Lovenula raynerae, reported from temporary wetlands in the Eastern Cape province of South Africa. We tested whether the species represents a single, well‐connected population or comprises different regional genetic groups, some of which may be rare or endangered.

- Description: Ringing activity in the Eastern Cape province, South Africa, spanned 30 years, with three sites active concurrently over a 14-year period, and three sites over a 6-year period. In total, in the course of 714 ringing days, in all months, we handled 1 207 Amethyst Sunbirds, 708 Southern Double-collared Sunbirds, 707 Greater Double-collared Sunbirds, 381 Grey Sunbirds, 121 Malachite Sunbirds and 140 Collared Sunbirds. Although individuals of all six species were recaptured more than five years after ringing, and despite evidence of the seasonal passage of sunbirds at two sites near the Indian Ocean coast, no birds were recaptured away from the original ringing site.

- Description: The South African spearfishery targets a variety of data-deficient species, which are consequently poorly managed. This study aimed to describe the age and growth of one of these species, the Cape knifejaw, Oplegnathus conwayi, which is endemic to the southern and eastern coasts of South Africa. Monthly biological samples were collected through research spearfishing (n = 170) and augmented by recreational spearfishers’ catches (n = 135). The results indicated that the O. conwayi population sex ratio was skewed towards males (1M:0.6F). The length- and age-frequency distributions were similar between sexes. Oplegnathus conwayi is a relatively slow-growing species, with a maximum-recorded age of 27 years. No significant differences were observed between male and female growth, with the overall population growth curve being best described as L(t) = 697.15(1 − e−0.06(t−6.30)). The slow growth observed in this species is characteristic of a species that is vulnerable to overexploitation, and accordingly a precautionary approach to future management is recommended.

Breaking the Rules: Zodwa Wabantu and postfeminism in South Africa

- Description: Zodwa Wabantu, a South African celebrity recently made popular by the Daily Sun, a local tabloid newspaper, is notorious as an older working-class woman who fearlessly challenges social norms of feminine respectability and beauty. Her assertion of sexual autonomy and her forays into self-surveillance and body-modification, mediated by the Daily Sun and other tabloid and social media platforms, could be read as a local iteration of a global postfeminist subjectivity. However, the widespread social opprobrium she faces must be accounted for: Using Connell’s model of the gender order together with a coloniality frame, I argue that northern critiques of postfeminism omit to consider the forms of patriarchy established by colonialism in southern locales such as South Africa. The local patriarchal gender order, made visible within the tabloid reportage, provides the context within which the meaning of Zodwa Wabanu’s contemporary postfeminist identity is constructed. I examine a range of Zodwa Wabantu’s (self)representations in Daily Sun and other digital media in the light of this context, and conclude that a close examination of the local gender order assists in understanding the limits of postfeminism’s hegemony.

- Description: Hyphaene coriacea and Phoenix reclinata are two abundant palm species in the Maputaland coastal plains of southern Mozambique. They provide an array of subsistence and commercial non- timber forest products. This research characterizes the ethnobotanical knowledge and uses of these species. Using structured interviews we assessed the knowledge, past and current uses, cultural importance and the determinants of the knowledge and current uses of these species. The knowledge about the uses of these two palms is widespread, however only 32% of respondents are engaged in palm exploitation. Thirteen palm products are used in the area with palm wine production from the sap of both species being the dominant activity, followed by broom production.

- Description: The inclusion of new environmental knowledge in the South African Geography Curriculum and Assessment Policy Statement (CAPS) has meant that many student teachers are unprepared to teach a systemic process like catchment and river management, which concerns the management of water catchment basins and the rivers within. New environ-mental knowledge, by definition, involves systems thinking towards a grasp of social-ecological systems, notably cause and effect processes, and circularity within a system. A so-cial-ecological system is the complex relationship between the social and ecological processes on a parcel of land. The need for such systems thinking is implicit in the catchment and river management component of the CAPS (South Africa DBE 2011). The teaching of a case study of a catchment management system (which is the management system that governs a water catchment basin) has never been included in any previous curriculum. Water management has devel-oped on a widening scale into the 21st century in South Afri-ca, but there was little comprehensive data on catchment management systems until 2017. It was only in July 2017 that a draft catchment management strategy was published. Hence it is not surprising that no curriculum case studies ex-ist since there was no data to base them on (Meissner et al. 2017). An internet search in June 2020 uncovered no trace of any catchment management strategy for the more densely populated and, arguably, more significant eastern catch-ments of the country.

- Description: Land reform is an important socio-political strategy in many countries. Despite the importance of ecosystem health in attaining land reform objectives, human-nature interactions have been largely absent from contemporary land reform discussions. In this perspectives paper, we highlight why land reform programmes could benefit from considering ecosystem services in their planning processes, to better achieve their goals of socio-economic development and equity. Drawing on examples from South Africa, we argue that an ecosystem services lens can help achieve equity in land reform programmes by providing insight into how land-use legacies and the multi-functional nature of landscapes influence who benefits from land reform across space and through time.

The record of phosphorus in sediments, which has no notable source within the ocean, and the radiogenic strontium isotopes in Archean carbonates indicate that, prior to the Great Oxidation Event (GOE), subaerial expanses represented only about 20% of the modern continental surface area, i.e. 7% of the surface of the Earth. Because these simple first-order observations, in contrast to the low oxygen content of the pre-GOE atmosphere, have so far received only little attention in the appraisal of the marine chemistry of the early Earth, a reassessment of the chemistry of the pre-GOE ocean is warranted. Here we discuss some of the geochemical cycles of the Archean world, including protons, alkalinity, electrons, and other electrolytes, and attempt to build a first conceptual framework for Chemical Archeoceanography.

- Description: The contribution of ecosystem services to smallholder agriculture is widely recognised. However, they are seldom analysed in tandem with the ecosystem disservices, such as crop weeds and pests, which the same systems produce. We do so by quantifying the provisioning ecosystem services and disservices in smallholder arable agricultural systems in three rural villages in southeastern South Africa. Using a mixed methods approach we consider the relative benefits from ecosystem services after the effects of disservices, and the management and strategies that households adopt to minimise disservices. The role of ecosystem services and disservices was expressed in economic terms to provide a common framework to assess the relative magnitude of their contribution or loss.

- Description: Quantifying organismal sensitivity to heat stress provides one means for predicting vulnerability to climate change. Birds are ideal for investigating this approach, as they display quantifiable fitness consequences associated with behavioural and physiological responses to heat stress. We used a recently developed method that examines correlations between readily‐observable behaviours and air temperature (Tair) to investigate interspecific variation in avian responses to heat stress in seasonally hot, arid regions on three continents: the southwestern United States, the Kalahari Desert of southern Africa and the Gascoyne region of western Australia.

- Description: This study presents an integrated examination of both the ecosystem services (ES) and ecosystem disservices (EDS) associated with smallholder animal husbandry in rural livelihoods in three villages in southeast South Africa. It recognises the contribution of ES supporting and resulting from smallholder livestock and poultry production, but also details the limiting factors or EDS, such as tick-borne disease, birds of prey or unpalatable rangeland, produced by the same system. Using a mixed-methods approach, including focus group discussions with various Participatory Learning and Action (PLA) activities, key informant interviews, household surveys and land-use change mapping on GIS, we consider the relative value and benefits from ES after the effects of EDS, as well as the management and strategies that households adopt to minimise EDS.

- Description: Urban green infrastructure (UGI) provides numerous environmental, social and economic benefits through direct and indirect use of ecosystem services. The maintenance of UGI also provides work opportunities for skilled and unskilled workers in the public and private sectors, so-called green collar jobs. However, the extent and benefit of such employment has rarely been examined, especially in a developing country context where unemployment is often high. We quantified the number of green collar jobs and wage levels across all green collar categories in 12 towns of the Eastern Cape via means of questionnaires and interviews. Overall, we enumerated 17 429 jobs, receiving approximately ZAR503 million (US$37 million) per year. The number of jobs was strongly linked to town size, but the number of jobs per unit area was inversely related to the level of underdevelopment or deprivation per town.

- Description: The Rhodes University Library strategic plan 2020 - 2022 is informed by the 2020 Academic Library standards developed by the Committee of Higher Education Libraries in South Africa (CHELSA), a coalition of all 26 Higher Education Libraries in South Africa. The standards seek to advance the role of academic libraries as partners to the teaching, learning and research endeavors of South African higher education institutions. The framework is further influenced by the principles as laid down by the 2018 National Policy for Library and Information Services (LIS) in South Africa which seeks to promote and develop the LIS Sector to contribute to the development of a responsive, responsible, and deliberative informed and reading nation. The Strategy is aligned to the Rhodes University (RU) Institutional Development Plan (2018 -2022) and the seven (7) RU goals outlined in the 2020 RU Annual Performance Plan. The seven RU goals are premised from the two most important documents that define the academic project; the RU Institutional Development Plan (IDP) and transformation imperatives document, the RU Institutional Transformation Plan (ITP). The Strategy is made up of the four strategic elements; the overall RU Vision and Mission, the LIS Purpose Statement, Values, Broad Focus Areas (BFAs)and Key Performance Areas (KPAs) that are all aligned to the seven (7) RU goals. Both the vision and mission are derived from the institutional IDP. The LIS further developed purpose statement, values, developed the BFAs and KPAs that translated to action plans and activities that form the Annual Operating Plan for the LIS.

- Description: Urban greenery provide a variety of goods and services to city dwellers. A core one is amelioration of the urban heat island effect. However, the many estimates from temperate regions cannot be extrapolated to the tropics, where more empirical studies are required to guide urban planning and optimization of green infrastructure design and distribution. This study reports on the temperature differentials in fortnightly readings, in winter and summer, between 12 urban green spaces and the surrounding built-up urban matrix at increasing distances from each green space. Additionally, the value of energy costs saved for air conditioning by urban greenery was calculated.
