- Description: The Okavango River Basin is a hotspot of bat diversity that requires urgent and adequate protection. To advise future conservation strategies, we investigated the relative importance of a range of potential environmental drivers of bat species richness and functional community composition in the Okavango River Basin. During annual canoe transects along the major rivers, originating in the central Angolan highlands, we recorded more than 25,000 bat echolocation calls from 2015 to 2018. We corrected for possible biases in sampling design and effort.

- Description: Limited knowledge of wetland geomorphic processes often results in poor wetland management. This study aims to illustrate the importance of incorporating geomorphic knowledge of wetland origin in their management. The geomorphic origin and dynamics of the Kafue wetland were determined from the analysis of remotely sensed and geological data. The wetland is a remnant of a paleo-lake that was captured by the tributary of the middle Zambezi River. At the point of capture, resistant Muva Group metavolcanic rocks dominate narrow valleys characterised by straight channels. The resistant lithology prevents the lower Kafue River to cut into the wetland thus maintaining wetland conditions upstream. Sedimentation regime through overbank and bed deposits shaped the wetland’s structure, ecological diversity, and hydrological functioning. The operation of the Itezhi-tezhi dam has negatively impacted the wetland’s hydrological and sedimentological regime. The dam starves the system of sediment needed for promoting levee and channel bed aggradation. Regulated discharge with reduced sediment load can lead to channel incision and therefore reduce flood frequency, which may ultimately lead to wetland desiccation.

- Description: The Expanded Public Works Programme (EPWP) in South Africa is an extensive governmental intervention to provide work opportunities. The EPWP context is a significant site of green skills emergence in South Africa, especially at the elementary occupation level. The training associated with these programmes has, to date, been largely top down, and little nuanced understanding exists on the training and learning pathways potential development for these green skills. There is a paradox between the top down approach to training, and the primarily regional implementation platforms of EPWP job opportunities and their developmental intent. To reconcile this paradox, I draw on social ecosystemic skills research to probe the potential for such a conceptual and theoretical framework for guiding green skills research for the EPWP. I share some methodologies and insights developed in EPWP green skills research projects that offer potential for providing insight into a social ecosystemic model for green skills research in EPWP programmes. Social ecosystemic models in skills research seek to develop skills development approaches that forge stronger connections between working, living and learning, foregrounding regional, place-based models for skills planning that require interfacing with vertical facilitatory mechanisms and horizontal connectivities.

- Description: Large swathes of arable fields have been abandoned in many areas of the world over the last few decades driven by a multitude of local and broader-scale factors. Many former fields experience a change in vegetation composition and structure post-abandonment, typically through a process of plant succession. The changes in species and abundance mean that the nature and quantity of ecosystem services provided by the former fields also varies. We examined the types of provisioning services obtained from non-timber forest products (NTFPs) with increasing age since field abandonment. We sampled 43 former fields ranging in age since abandonment from approximately 7 to 55 years, and seven plots in intact forests. We held seven focus group discussions with local residents to determine uses of species found in the former fields.

Against this backdrop, in this article we focus on the academic leadership role of Heads of Departments (HoDs) at Rhodes University. In this small-scale project we interrogate how HoDs conceptualised their roles in this uncertain and complex context. From the data analysis a number of tensions emerged in the ways in which they articulated and enacted their roles. The findings indicate that the protests have contributed to the increasing complexity of the role of an HoD. Issues raised during the protests catalysed HoDs at Rhodes University, some for the first time, into considering the implications of the decolonising call from students and into exercising stronger transformative leadership roles.

We have previously demonstrated that FN interacts directly with Hsp90, as well as showing that the Hsp90 inhibitor novobiocin results in FN turnover via a receptor mediated process. However, the receptor involved has not been previously identified. LRP1 is a ubiquitous receptor responsible for the internalisation of numerous ligands that binds both Hsp90 and FN, and therefore we investigated whether LRP1 was involved in novobiocin-mediated FN turnover.

For many South African writers, London comes to stand metonymically for English culture and literature even if their attitude toward Englishness and Empire may be one of ambivalent critique. The intertexts invoked in South African representations of London forge literary solidarities, and foreground belated postcolonial engagements with modernity that are significantly displaced from the “margin” to the “center” of modernism (and Empire) itself.

- Description: publisher version , This article reports on the role and value of social reflexivity in collaborative research in contexts of extreme inequality. Social reflexivity mediates the enablements and constraints generated by the internal and external contextual conditions impinging on the research collaboration. It fosters the ability of participants in a collaborative project to align their interests and collectively extend their agency towards a common purpose. It influences the productivity and quality of learning outcomes of the research collaboration. The article is written by fourteen members of a larger research team, which comprised 18 individuals working within the academic development environment in eight South African universities. The overarching research project investigated the participation of academics in professional development activities, and how contextual, i.e. structural and cultural, and agential conditions, influence this participation. For this sub-study on the experience of the collaboration by fourteen of the researchers, we wrote reflective pieces on our own experience of participating in the project towards the end of the third year of its duration. We discuss the structural and cultural conditions external to and internal to the project, and how the social reflexivity of the participants mediated these conditions. We conclude with the observation that policy injunctions and support from funding agencies for collaborative research, as well as support from participants’ home institutions are necessary for the flourishing of collaborative research, but that the commitment by individual participants to participate, learn and share, is also necessary.

- Description: publisher version , This article reports on the role and value of social reflexivity in collaborative research in contexts of extreme inequality. Social reflexivity mediates the enablements and constraints generated by the internal and external contextual conditions impinging on the research collaboration. It fosters the ability of participants in a collaborative project to align their interests and collectively extend their agency towards a common purpose. It influences the productivity and quality of learning outcomes of the research collaboration. The article is written by fourteen members of a larger research team, which comprised 18 individuals working within the academic development environment in eight South African universities. The overarching research project investigated the participation of academics in professional development activities, and how contextual, i.e. structural and cultural, and agential conditions, influence this participation. For this sub-study on the experience of the collaboration by fourteen of the researchers, we wrote reflective pieces on our own experience of participating in the project towards the end of the third year of its duration. We discuss the structural and cultural conditions external to and internal to the project, and how the social reflexivity of the participants mediated these conditions. We conclude with the observation that policy injunctions and support from funding agencies for collaborative research, as well as support from participants’ home institutions are necessary for the flourishing of collaborative research, but that the commitment by individual participants to participate, learn and share, is also necessary.

- Description: Streams and riparian areas are tightly coupled through reciprocal trophic subsidies, and there is evidence that these subsidies affect consumers in connected ecosystems. Most studies of subsidies consider only their quantity and not their quality. We determined the bidirectional exchange of organisms between the Kowie River and its riparian zone in South Africa using floating pyramidal traps (to measure insect emergence) and pan traps (to capture infalling invertebrates).

- Description: The call for the ‘transformation’ of higher education in South Africa is one instance of a wider effort, since the country’s first democratic election in 1994, to surmount an apartheid and colonial legacy of institutionalised racism. In 2015 and 2016 nationwide protests led to universities being shut down as students and staff expressed frustration institutions that continue to be experienced as racist and ‘untransformed’. In this study we report on interviews conducted with senior white academics at one South African university shortly before these protests began. Given that our participants are people of influence in their respective university departments, we asked, in in-depth open-ended interviews, what contribution they saw themselves making to ‘transformation’. We argue that the talk of these participants could be described as what authors in the field call 'racetalk', Talk is understood here as a form of social practice, the analysis of which helps us to understand how racism is reproduced in mundane ways which, taken together, account for the persistence of pervasive institutionalised racism in South African higher education that appears impervious to policy and regime change.

- Description: Enteroviruses are responsible for a multitude of human diseases. Expansion of the virus capsid is associated with a cascade of conformational changes that allow the subsequent release of RNA. For the first time, this study presents a comprehensive bioinformatic screen for the prediction of interacting motifs within intraprotomer interfaces and across respective interfaces surrounding the fivefold and twofold axes. The results identify a network of conserved motif residues involved in interactions in enteroviruses that may be critical to capsid stabilisation, providing guidelines towards developing antivirals that interfere with viral expansion during RNA release.

- Description: Several scholars have noted that citizen journalism in the West is essentially an online phenomenon, driven by the affordability of Internet technologies. In Africa, projects such as Ushahidi in Kenya have been enabled by platforms such as cell phones and social networks. Voices of Africa, based in southern Africa, publishes on the web only. Publishing on the Internet presumes a citizenry which is relatively well educated; has familiarity with, and access to, new media as a form of social communication; and is confident in their right to participate in newly developed public spheres – particularly those online.

Privilege, poverty, and pedagogy: reflections on the introduction of a service-learning component into a postgraduate political studies course

- Description: This paper reflects on the experience of integrating a service-learning component into a postgraduate course in political studies. The course in question aims to get students to reflect on the ways in which poverty and privilege are tied up with each other, and on whether and how the relatively privileged can be involved in helpful ways in struggles against oppression. The service-learning component involved spending a week volunteering with a rural community-based organisation. Students were required to relate their volunteering experience to the course content. The paper reflects on the implications of the course's failure to live up to many criteria for quality service-learning, arguing that despite its failings, the service-learning experience significantly enhanced the learning of the students and also my own learning as an educator. I show that the nature of this learning calls into question some possible assumptions about how service-learning ought to be done. The paper contributes to ongoing discussions about the ways in which service-learning can assist in the achievement of social justice-related goals.
