Advances in satellite remote sensing of the wetland ecosystems in Sub-Saharan Africa
(Taylor and Francis Group, 2022)Wetlands are highly productive systems that act as habitats for avariety of fauna andflora. Despite their ecohydrological signifi-cance, wetland ecosystems are severely under threat from globalenvironmental changes as well ... -
Development of a compendium of local, wild-harvested species used in the informal economy trade, Cape Town, South Africa
(Resilience Alliance, 2012)Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural ... -
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)The process of species description is not random, and understanding the factors that in- fluence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' ... -
Does the landscape functionality approach provide insight into rangeland conditions in the Tanqua Karoo region, South Africa?
(PeerJ, 2022)The harsh environmental conditions coupled with a long history of overgrazing have altered the ecology of the arid Tanqua Karoo rangelands in South Africa, which necessitates rehabilitation. However, a suitable method ... -
Impacts of plastic debris on biota and implications for human health: A South African perspective
(South African Assn. For The Advancement Of Science, 2020)Entanglement and ingestion of plastics are the main ecological impacts of marine plastic debris on marine biota, but indirect effects such as the transport of alien species and benthic smothering are also important to note. ... -
Iterative mapping of marine ecosystems for spatial status assessment, prioritization, and decision support
(Frontiers Media, 2023)South Africa has taken an iterative approach to marine ecosystem mapping over 18 years that has provided a valuable foundation for ecosystem assessment, planning and decision-making, supporting improved ecosystem-based ... -
Temporal partitioning of Bullacris unicolor (Orthoptera: Pneumoridae) calling activity to avoid predation
(Taylor and Francis Group, 2023)Ecological interactions, including competition, predation, and environmental conditions, may significantly impact acoustic signal-ling behaviour. Here we characterise nocturnal signalling patterns in the bladder grasshopper ... -
Topography-derived variables provide insight into habitat occupancy of a cryptic snake, Bitis atropos
(Wiley, 2021)Understanding species’ habitat use is fundamental for conservation and management. However, quantifying habitat use for small cryptic species is limited by imperfect detection during field surveys and the lack of habitat ... -
Understanding the influence of land cover change and landscape pattern change on evapotranspiration variations in Gwayi catchment of Zimbabwe
(Taylor and Francis Group, 2022)Understanding dynamics in hydrological processes helps toimprove water resource management. Climate and land coverchanges influence ecohydrological processes. This study soughtto assess the influence of climate, land ... -
Use of multispectral satellite data to assess impacts of land management practices on wetlands in the Limpopo Transfrontier River Basin, South Africa
(Taylor and Francis Group, 2022)The study sought to assess the impacts of land use and land cover (LULC) changes on two wetland systems (Makuleke and Nylsvley Nature Reserve) in the Limpopo Transfrontier River Basin (LTRB) in South Africa between 2014 ... -
Use of remotely sensed data to estimate tree species diversity as an indicator of biodiversity in BloubergNature Reserve, South Africa
(Taylor and Francis Group, 2022)We use remotely sensed data to estimate species diversity inBlouberg Nature Reserve (BNR) in the Limpopo province, SouthAfrica to understand the state of biodiversity since communities’involvement in conservation initiatives. ...
