Spatiotemporal variation in microplastic contamination along a subtropical reservoir shoreline.

Microplastics have become a major environmental concern globally due to their potential impact on ecosystem function. They are known to be ubiquitously present, persistent and bio-accumulative, yet there is a lack of abundance quantifications in freshwater shorelines. Furthermore, there is little understanding of combined effects of seasonality and human population density on the extent of microplastic pollution.

Functional response quantifies microplastic uptake by a widespread African fish species.

Ecological impacts of microplastic remain poorly understood, despite their ubiquity across all habitat types globally. Microplastic concentrations vary significantly across spatiotemporal gradients, however we lack quantitative methodologies to predict species-level responses to differential environmental concentrations. In the present study, we expose a key species, the banded tilapia Tilapia sparrmanii Smith, 1940, to different concentrations of microplastic particles.

The impact of and responses to flooding in Thulamela Municipality, Limpopo Province, South Africa.

The frequency of climate-related disasters such as floods is growing due to environmental and human factors. This paper examines the impact of flooding and communities' perceptions towards responses to flooding in the cases of Maniini and Tshilungwi Villages in the Thulamela Municipality in the Limpopo Province of South Africa. A questionnaire survey was conducted with 60 household respondents in the two selected villages and then analysed.
