- Description: Local and indigenous knowledge is being transformed globally, particularly being eroded when pertaining to ecology. In many parts of the world, rural and indigenous communities are facing tremendous cultural, economic and environmental changes, which contribute to weaken their local knowledge base. In the face of profound and ongoing environmental changes, both cultural and biological diversity are likely to be severely impacted as well as local resilience capacities from this loss. In this global literature review, we analyse the drivers of various types of local and indigenous ecological knowledge transformation and assess the directionality of the reported change. Results of this analysis show a global impoverishment of local and indigenous knowledge with 77% of papers reporting the loss of knowledge driven by globalization, modernization, and market integration. The recording of this loss, however, is not symmetrical, with losses being recorded more strongly in medicinal and ethnobotanical knowledge. Persistence of knowledge (15% of the studies) occurred in studies where traditional practices were being maintained consiously and where hybrid knowledge was being produced as a resut of certain types of incentives created by economic development. This review provides some insights into local and indigenous ecological knowledge change, its causes and implications, and recommends venues for the development of replicable and comparative research. The larger implication of these results is that because of the interconnection between cultural and biological diversity, the loss of local and indigenous knowledge is likely to critically threaten effective conservation of biodiversity, particularly in community-based conservation local efforts.

“Having it all”?’: ”?:(re) examining conspicuous consumption and pernicious masculinities in South African chick-lit

- Description: A number of South African women writers have taken up chick-lit as a form of writing that enables them to reflect on the experiences of the modern woman in post-apartheid South Africa. The protagonists portrayed in chick-lit narratives occupy ambiguous positions: they may have benefitted from feminist politics, which has opened new possibilities for them; however, underlying this emancipation is an implicit collusion with patriarchy. Chick-lit refuses to offer a clear-cut construct of women’s lives; instead, it suggests a problematic terrain that is inherently ambiguous and contradictory, simultaneously empowering and oppressing women. It depicts a realistic world where contemporary women critique patriarchy and attempt to break free of its stranglehold by finding new methods of self-realisation. In this article, I argue that as a genre chick-lit offers a space of recognition and reflection for women who share a similar world view and emotional knowledge that stems from a common historical experience.

- Description: Fish are constantly in contact with pathogens inhabiting water. High population density as well as poor hydrodynamic conditions and feeding lead to an increased sensitivity towards infections. In order to prevent major economic losses due to diseases, various medications are used for treatment and prevention of infections. The use of antimicrobial drugs in aquacultures could lead to emergence of resistance in pathogenic microorganisms. Alternatives are being sought over the last few years to replace antibiotics, and medicinal plants are one of available options for this purpose. These plants are rich in secondary metabolites and phytochemical compounds, which have an effect against viral, bacterial, and parasitic diseases in fish. Their main advantage is their natural origin and most of these plants do not represent threat for human health, the fish, and the environment. The goal of this review is to present information on the treatment of viral, bacterial, and parasitic diseases in fish through medicinal plants, with focus on the mechanisms of action of the identified secondary metabolites, fractions, or plant extracts.
