(Oxford, 2024)We report here on the timing of 597 pulsars over the last four years with the MeerKAT telescope. We provide times of arrival, pulsar ephemeris files, and per-epoch measurements of the flux density, dispersion measure (DM), ... -
The effects of Jurassic igneous intrusions on the generation and retention of gas shale in the lower permian source-reservoir shales of karoo basin, South Africa
(Elsevier B.V, 2023)Shale gas potential of the Whitehill Formation (Permian), Karoo Basin, South Africa is strongly influenced by widespread Jurassic igneous intrusions. A high-resolution organic petrographic and geochemical study is reported ... -
Understanding climate change effects on the potential distribution of an important pollinator species, ceratina moerenhouti (apidae: ceratinini), in the eastern afromontane biodiversity hotspot, Kenya
(Elsevier Ltd, 2023)Monitoring key pollinator taxa such as the genus Ceratina requires precise near real-time predictions to facilitate better surveillance. The potential habitat suitability of Ceratina moerenhouti was predicted in the Eastern ... -

From benthic to floating: phytoplankton dynamics in African freshwater lakes and reservoirs
(Elsevier, 2023)This chapter reviewed phytoplankton communities in African freshwater lakes and reservoirs and further assessed the latitudinal diversity gradient (LDG) which has been used to explain species variations in other taxonomic ... -
Multispectral remote sensing of wetlands in semi-arid and arid areas: A review on applications, challenges and possible future research directions
(Remote Sensing, 2022)Wetlands are ranked as very diverse ecosystems, covering about 4–6% of the global land surface. They occupy the transition zones between aquatic and terrestrial environments, and share characteristics of both zones. Wetlands ... -
Impacts of climate variability and drought on surface water resources in sub-saharan africa using remote sensing: A review
(Remote Sensing, 2022)Climate variability and recurrent droughts have caused remarkable strain on water resources in most regions across the globe, with the arid and semi-arid areas being the hardest hit. The impacts have been notable on surface ... -
Trends in elephant poaching in the Mid-Zambezi Valley, Zimbabwe: Lessons learnt and future outlook
(African Journal of Ecology, 2023)Background: The conservation of African elephants (Loxodonta africana) has important ecological, economical, cultural and aesthetic values, at both local and global levels (Pittiglio et al., 2014). Despite the important ... -
The use of stable isotopes to identify surface water–groundwater interaction in the Kruger National Park, South Africa
(South African Water Research Commission, 2023)The role of groundwater, in general, is often overlooked in freshwater ecosystem management policies and in the management of South Africa’s flagship conservation area, the Kruger National Park (KNP). To address this gap, ... -
Modelling the distribution of the invasive Ziziphus mauritiana along road corridors in Zimbabwe
(Wiley, 2019)We investigate how human fruit consumption affects the spread of the alien invasive Ziziphus mauritiana along road corridors in northern Zimbabwe. A field survey was conducted to identify and map Z. Mauritiana stems at ... -
Two pulses of Mesoproterozoic intra-plate magmatism in the heart of the Palaeoproterozoic Ubendian Domain of northern Malawi
(Elsevier, 2023)Two Mesoproterozoic anorogenic igneous events are recorded in the Palaeoproterozoic Ubendian Domain in northern Malawi. The oldest is represented by the Mwakikome orthogneiss, a small peraluminous, sub-alkaline and ferroan ... -
