Spatial and temporal variations in the geometry and composition of the Permian Whitehill Formation South Africa
Published 2017“…Although the formation is composed predominantly of black laminated carbonaceous shales, earlier studies detected significant spatiotemporal variability in its stratigraphy and composition, particularly the distribution of its organic carbon content across the basin. …”

Comparative foraging ecology of macaroni and rockhopper penguins at the Prince Edward Islands
Published 2018“…Given the rapid ongoing ecosystem changes in the Southern Ocean, it is vital to better understand, firstly, how penguins respond to environmental variability, and secondly, how such changes alter ecological relationships between sympatric species. …”

The impact of submesoscales on the stratification dynamics in the Southern Ocean
Published 2019“…Furthermore, the parameterization dramatically improves the sub-seasonal variability of mixed layer stratification, particularly during the onset of seasonal restratification when the mixed layer remains deep despite a positive surface heat flux. …”

Assessing the value of ecological intensification in improving smallholder farmers' food security and rural livelihoods in a changing climate
Published 2023“…This study aimed to assess the value of ecological intensification of agriculture to improve food production systems and environmental sustainability in smallholder farming systems in the face of climate variability and change. This study uses two rural districts in South Africa namely Vhembe and Amathole from Limpopo and the Eastern Cape provinces respectively as a case study to explore how ecological intensification can help smallholder farmers. …”

Individual contributions to group behaviour in the cooperatively breeding southern ground-hornbill Bucorvus leadbeateri
Published 2023“…In birds, cooperative breeding is found mainly in harsh regions with greater environmental variability, such that individuals might do better to help relatives than attempt to breed themselves. …”

Investigating the trophic ecologies of early life stages of small pelagic fishes in the Benguela upwelling ecosystem
Published 2024“…In terms of overall model function, there was no change in biomass or system variability. However, there was a significant change in the trophic level estimation of functional groups, that had system-wide ramifications. …”

Zimbabwe's CAMPFIRE public investments: impact on education, adaptation and preferences
Published 2021“…Results of the education production function confirm that the CAMPFIRE programme affects the individual components of adaptive capacity variably; negatively on household social, economic capacities, and positively on household physical capacity, with no significant effect on human capacity and overall household adaptive capacity. …”
