(2000)Lakes are an important resource. They provide vital ecosystem services and employment for many communities worldwide. Maintaining lakes as ecosystem providers without damaging the lake ecosystems themselves, against a ... -
Recasting the Sangoan Stone Age Techno-Complex in the Stone Age Nomenclature at Sango Bay, Southern Uganda
(Studies in the African Past, 2022)This paper discusses the complex use of the term ‘Sangoan’ and its placement between the Early Stone Age (ESA) and Middle Stone Age (MSA) using data from Simba Hill in Sango Bay. The purpose is to examine whether the Sangoan ... -
Land use and land cover change influence on soil organic carbon content for a pastoral area: use of geographical information system
(East African Journal of Science, Technology and Innovation, 2022)Data on land use and cover change and soil organic carbon (SOC) in rangelands are essential. This is because rangelands ecosystems are fragile, and poor land-use practices can significantly threaten their sustainability ... -
The Challenges of Reconstructing Tropical Biodiversity With Sedimentary Ancient DNA: A 2200-Year-Long Metagenomic Record From Bwindi Impenetrable Forest, Uganda
(Frontiers in Ecology and Evolution, 2020-07-10)Sedimentary ancient DNA has been proposed as a key methodology for reconstructing biodiversity over time. Yet, despite the concentration of Earth’s biodiversity in the tropics, this method has rarely been applied in this ... -
Minerals in the Foods Eaten by Mountain Gorillas (Gorilla beringei)
(PLoS ONE, 2014)Minerals are critical to an individual’s health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas ... -
