Our research explores the experience of adults looking for flexible online learning opportunities that intersect with university study. We interviewed 58 people living in 14 African countries who have taken a Massive Open Online Course (MOOC) developed by the University of Cape Town. The interview data reveals diverse uses of MOOCs in workplace contexts. While only two of those we interviewed articulated a goal of making a career change, there were many more taking a MOOC for some form of self-development within their current profession. There were also cases where people had not yet identified a new career, but believed the knowledge and skills would support future transitions. Our intentions for exploring the expectations of MOOC takers regionally is to improve our understanding of how universities, following open practices, could support the educational aspirations of this audience through the provision of flexible online learning opportunities.

MOOCs have been seen as holding promise for advancing Open Education. While the pedagogical design of the first MOOCs grew out of the Open Education Movement, the current trend has MOOCs exhibiting fewer of the original openness goals than anticipated. The aim of this study is to examine the practices and attitudes of MOOC educators at an African university and ask whether and how their practices and attitudes become open after creating and teaching a MOOC. Activity Theory is used to contextually locate the educators' motivations and to analyse their practices in terms of striving towards an object. With this lens we describe how educators' openness-related practices and attitudes change over time in two different MOOCs. Two sets of conceptions of open practices are used to detect instances of change, providing four dimensions of changed open educational practices. Semi-structured interviews, focus groups, and artefacts provide data for this rare study, which considers these issues from the perspective of the Global South. Through studying the educators' practices in relation to openness, it becomes evident how open practices are emergent and responsive.

The diurnal activity budgets of giraffes were effectively studied from June 2012 until August 2013, in the Kalahari Region of southern Africa. Direct field observations identified how the daily activity budgets varied amongst the different subgroups of giraffes and the effects of seasonal changes and the time of the day. Feeding was the highest-performed activity whilst non-feeding activities were, however, also prominent. This study aimed to determine why giraffes are willing to sacrifice time on nonfeeding activities. A deeper look into the social and non-feeding-related behaviour of giraffes might prove that giraffes devote significant time to various other activities to improve their health and comfort. It unveils trade-offs between digestion efficiency and foraging, impacting energy gain. Understanding this balance informs conservation strategies, habitat management and their well-being. Investigating the motivations behind these behavioural choices unveils adaptive mechanisms, shedding light on the intricate interplay between physiological and ecological needs, ultimately contributing to a holistic comprehension of giraffe's ecological roles and promoting their coexistence with their environment. Such investigations also aid in highlighting why giraffes' social structures should be considered as complex and why further research is needed to better understand these relationships, amongst subspecies.

Aim: Ecological traits (e.g. biotope specialisation and habitat preference) and biological traits (e.g. mobility and life history) are highly variable among species. In insect conservation, considerable focus has been on ecological generalisation, with species occupying many biotope types (generalists) often assumed to be widely distributed, whereas species occupying few biotope types (specialists) are assumed as rare and localised. Although this may be valid in most cases, there is an increasing recognition that functional traits, such as insect mobility and life history, have similar importance as drivers of range size among species. Here, we investigate ecological and biological traits simultaneously to determine their relative importance as drivers of range size variation. We hypothesise that ecological traits are primary drivers, whereas biological traits related to mobility and life history are less important drivers of range size. Location: Sub‐Saharan Africa. Taxon: 115 sub‐Saharan dragonfly species. Methods: Five measures of species range size were obtained from the Odonata Database of Africa. Number of biotope types occupied by adults and larvae, larval habitat preference and adult biological trait information were collated from published sources. We explore the relationships between ecological and biological traits. Using linear mixed models and model averaging, we determine the relative importance of number of biotope types occupied, overall habitat preference and traits related to mobility and life history that drive dragonfly range size while accounting for phylogenetic relationships among focal species. Results: Dragonflies occupying more biotope types had wider ranges, although these relationships were overall weak. Dragonflies with longer and later breeding seasons had wider ranges. Overall habitat preference and mobility traits had low importance in our models. Main conclusions: Ecological versus biological traits are interactive in shaping the geographical ranges of dragonfly species across Africa. Single traits are weak predictors of species range sizes and we recommend investigating multiple traits simultaneously to improve the accuracy of predictions. In doing so, more informed decisions can be made to ensure effective large‐scale conservation of dragonflies. [ABSTRACT FROM AUTHOR]

Artificial ponds assure continuous societal water supply, especially during droughts. Obligate aquatic and amphibiotic insects readily inhabit novel water bodies, as many possess mobility traits for opportunistic colonization. We review here the value of artificial ponds (< 2 ha) (and reservoirs; > 2 ha) for local aquatic insect diversity in mostly dry and drought-prone southern Africa. We compare these ponds to natural pools, wetlands, and stream deposition pools. The region has a highly varied topography and physiographical zones. Flat, arid areas largely support widespread insect generalists, while the mountainous orographic zones support an additional rich fauna of localized endemics. However, the many ponds (> 0.5 million) have greatly changed the local distribution patterns of surface freshwater across the region, increasing the area of occupancy for many aquatic insect species, especially dragonflies. We focus on the extent to which aquatic insect assemblages have benefitted from new ponds and reservoirs. We conclude that these novel ecosystems benefit almost all lentic aquatic insect species, while also enabling population resilience during droughts. However, while these benefits are substantial, these ponds are not a substitute for natural still waters, which are still required to maintain all indigenous lentic aquatic insect diversity.

Physiological colour change is rare in insects. Unusually, both the males and females of Spesbona angusta (Odonata: Platycnemididae), Red Listed as Endangered, are capable of rapid and reversible colour change. There is only one known population of this species, which occurs in a unique habitat in the Cape Floristic Region, South Africa. Appreciation of this unusual phenomenon of distinct physiological colour change helps us appreciate that we need to conserve phenomena in the insect world as well as the species themselves. Using controlled experiments, we evaluated the importance of ambient temperature as the possible primary cue for physiological colour change. We found that S. angusta responds rapidly to short-term changes in ambient temperature, even in the absence of additional environmental stimuli and without the body temperature matching the ambient temperature. Colour change is reversible when temperature returns to its earlier level. The reason why S. angusta shows this rapid and reversible colour change may be a combination of reproductive enhancement, competitive advantage and thermoregulation. This colour change appears to have strong selective advantage in a very particular habitat type, meaning that careful conservation of its habitat in all respects is important, and must be considered in any possible future translocations.

Recent largely unexplained deaths in African flamingos have prompted the need for standard, reproducible methods for thepost-mortemexamination of these birds, for the taking of samples and for the recording of findings. Here we describe suitable techniques and present three distinct protocols for field-basedpost-mortemexamination of flamingos that can be employed flexibly, depending on the circumstances, by veterinarians and non-professionals alike. The adoption of these protocols is strongly recommended to improve standardisation of data and sample collection, which will ultimately enhance our understanding of the causes of mortality in African flamingos.

The Cape Doctor, named after the profession as well as the wind that sweeps the Cape Peninsula of dangerous miasmas, is a social history of medicine, seeking to place formal western medicine within its political, social and economic context. Besides Shula Marks' study of South African nurses, Divided Sisterhood, no previous work has brought such a breadth of material about South Africa's medical past under the framework of social history. This work provides clear evidence of the way in which the Cape medical profession excluded all but a few women and black practitioners, and discriminated along lines of race, class and gender in their practice, but it also moves beyond the classic revisionist tradition (documenting the emergence of a society divided along lines of race and gender) by providing examples of cultural crossover and medical pluralism.

Simple Summary: The expansion of urban areas in combination with climate change places great pressure on species found in freshwater habitats. Dragonflies are iconic freshwater organisms due to their large body sizes and striking coloration. They have been widely used to indicate the impacts of natural and human-mediated activities on freshwater communities, while also indicating the mitigation measures required to ensure their conservation. Here, we review the major threats to dragonflies in southern Africa, specifically those in urban areas. We also provide information on effective mitigation measures to protect dragonflies and other aquatic insects in urban spaces. Using three densely populated areas as case studies, we highlight some of the greatest challenges for dragonflies in South Africa. More importantly, we give a summary of current mitigation measures which have maintained dragonflies in urban spaces. In addition to these mitigation measures, public involvement and raising awareness contribute greatly to the common cause of protecting dragonflies around us. Urban settlements range from small villages in rural areas to large metropoles with densely packed infrastructures. Urbanization presents many challenges to the maintenance of freshwater quality and conservation of freshwater biota, especially in Africa. There are many opportunities as well, particularly by fostering contributions from citizen scientists. We review the relationships between dragonflies and urbanization in southern Africa. Shifts in dragonfly assemblages indicate environmental change, as different species are variously sensitive to abiotic and biotic water and bank conditions. They are also conservation umbrellas for many other co-occurring species. Major threats to southern African dragonflies include increasing infrastructure densification, frequent droughts, habitat loss, pollution, and invasive alien vegetation. Mitigation measures include implementation of conservation corridors, maintenance of healthy permanent ponds, pollution reduction, and removal of invasive alien trees. Citizen science is now an important approach for supplementing and supporting professional scientific research. [ABSTRACT FROM AUTHOR]

Summary In a recent paper in Current Biology , Fennessy and colleagues [1] conclude that there are four species of giraffe and that their numbers are declining in Africa. Giraffes ( Giraffa camelopardalis ) are presently classified as one species, with nine subspecies, which are considered ‘Vulnerable’ on the IUCN Red List [2] . The present consensus of one species divided into nine subspecies has previously been questioned (Supplemental information), and Fennessy and colleagues [1] provide another viewpoint on giraffe taxonomy. The fundamental reason for different taxonomic interpretations is that they are based upon different datasets that adopt different statistical techniques and follow different criteria for nomenclature.
