Background: The KwaZulu-Natal Sandstone Sourveld (KZNSS) Research Programme is part of a collaborative, transdisciplinary research partnership between the University of KwaZulu-Natal and the eThekwini Municipality (EM), aimed at bridging the science-policy-practice gap. The research programme focuses on generating knowledge and capacity to support local land-use planning, management and policy development related to biodiversity and climate change issues. Objectives: The objectives were (1) to describe how a continuous reflective evaluation approach helped to better understand the research programme and its outcomes; and (2) to assess research outputs and outcomes, relevance of outcomes to the requirements of EM, and participants’ perceptions of the programme (both the outcomes and the process). Methods: The evaluation took a mixed methods approach, combining various quantitative and qualitative methods such as anonymous individual questionnaires, reflective exercises and group reflections. Results: The KZNSS programme was successful in capacity building and establishing a long-term partnership, but had lower scientific publication output and practice uptake than expected. Participants’ perceptions changed over time, with a decrease in the perceived success of addressing tangible research outcomes, and an increase in the perceived success of collaborative relationships in the partnership. Conclusion: Transdisciplinary partnerships can be a means of integrating research into policy and practice through knowledge exchange. An important lesson in the early stages of this partnership was to pay attention to the process and not only the outputs. The study highlights the importance of continuous participatory reflection and evaluation in such partnerships.

This study investigates genetic diversity in three species of Ephemeroptera, one eurytopic and therefore widespread (Afroptilum sudafricanum) and two stenotopic and thus endemic (Demoreptus natalensis and Demoreptus capensis) species, all of which co-occur in the southern Great Escarpment, South Africa. Mitochondrial DNA was analysed to compare the genetic diversity between the habitat generalist and the two habitat specialists. Afroptilum sudafricanum showed no indication of population genetic structure due to geographic location, while both Demoreptus species revealed clear genetic differentiation between geographic localities and catchments, evident from phylogenetic analyses and high FST values from AMOVA. In addition, the phylogenetic analyses indicate some deeper haplotype divergences within A. sudafricanum and Demoreptus that merit taxonomic attention. These results give important insight into evolutionary processes occurring through habitat specialisation and population isolation. Further research and sampling across a wider geographic setting that includes both major mountain blocks of the Escarpment and lowland non-Escarpment sites will allow for refined understanding of biodiversity and associated habitat preferences, and illuminate comparative inferences into gene flow and cryptic speciation.
