Development of the Nyika Plateau, Malawi: A Long Lived Paleo‐Surface or a Contemporary Feature of the East African Rift?

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022
Abstract Northern Malawi's Nyika Plateau is a 3,700 km2 large, highly elevated (∼2,500 m) plateau located at the western margin of the Miocene‐Recent Malawi rift and the confluence of multiple Proterozoic orogenic belts. Neighboring asthenospheric upwelling in the Rungwe Volcanic Province, associated with the active East African Rift, has created ...

Large Methane Emission Fluxes Observed From Tropical Wetlands in Zambia

Global Biogeochemical Cycles, Volume 36, Issue 6, June 2022., 2022
Abstract Methane (CH4) is a potent greenhouse gas with a warming potential 84 times that of carbon dioxide (CO2) over a 20‐year period. Atmospheric CH4 concentrations have been rising since the nineteenth century but the cause of large increases post‐2007 is disputed.

A Thermo‐Compositional Model of the African Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 3, March 2022., 2022
Abstract Recently, the continually increasing availability of seismic data has allowed high‐resolution imaging of lithospheric structure beneath the African cratons. In this study, S‐wave seismic tomography is combined with high resolution satellite gravity data in an integrated approach to investigate the structure of the cratonic lithosphere of ...

The contribution of fisheries-based households to the local economy (Capital and Labour) and national fish yield: A case of Lake Bangweulu fishery, Zambia

Scientific African, 2019
Fishing industry contributes 3.2% to the national Gross Domestic Product (GDP) and is important to the household, society and the environment. Despite its importance, fisheries based household is marginalized and underreported in national policy and ...

Geodetic Constraints on Cratonic Microplates and Broad Strain During Rifting of Thick Southern African Lithosphere

Geophysical Research Letters, Volume 48, Issue 17, 8 September 2021., 2021
Abstract Southern Africa is typically considered to belong to a single tectonic plate, Nubia, despite active faulting along the southwestern branch of the East African Rift System. We analyze regional Global Navigation Satellite System (GNSS) measurements, and find that the “San” microplate, situated south of the southwestern branch of the East African

Origin, Accretion, and Reworking of Continents

Reviews of Geophysics, Volume 59, Issue 3, September 2021., 2021
Abstract The continental crust is unique to the Earth in the solar system, and controversies remain regarding its origin, accretion and reworking of continents. The plate tectonics theory has been significantly challenged in explaining the origin of Archean (especially pre‐3.0 Ga) continents as they rarely preserve hallmarks of plate tectonics.

Going with the flow? Diversification of gastropods reflects drainage evolution in Africa

Journal of Biogeography, Volume 48, Issue 7, Page 1579-1593, July 2021., 2021
Abstract Aim The roles of geodynamics, climatic variability and landscape evolution in shaping aquatic biodiversity patterns on the African continent remain poorly understood. We studied the geographical origin and phylogenetic relationships of an Afrotropical freshwater snail genus to examine the role of drainage evolution on diversification and range

Alarming decline of bovids in Kasanka National Park, Zambia: A case study of the puku antelope (Kobus vardonii)

African Journal of Ecology, Volume 59, Issue 2, Page 387-398, June 2021., 2021
Abstract Knowledge about antelope populations and their status is a key for conservation. In November 2019, we used distance sampling to perform a re‐survey of the bovid species in Kasanka National Park, Zambia, with a focus on the puku (Kobus vardonii).

Diversity and host specificity of monogenean gill parasites (Platyhelminthes) of cichlid fishes in the Bangweulu-Mweru ecoregion [PDF]

Journal of Helminthology, 2017
AbstractThis study represents the first exploration of the parasite fauna of cichlid fishes in the Mweru-Luapula subregion (Central Africa). Twelve species of cichlids and 14 species of Monogenea from three genera (Cichlidogyrus, Gyrodactylus and Scutogyrus) were collected.
