Influence of the annual flood-pulse on catch per unit effort, condition and reproduction of Clarias gariepinus from the upper Okavango Delta, Botswana
(Tailor and Francis Online; https://www.tandfonline.com, 2016-03-07)Catch per unit effort (CPUE), length, weight and maturity data for Clarias gariepinus were collected during monthly gillnet surveys in the upper Okavango Delta between 2001 and 2009 to investigate their relationship with ... -
Effects of divergent migratory strategies on access to resources for Cape buffalo (Syncerus caffer caffer)
(Oxford University Press; https://academic.oup.com, 2016-12-05)Populations of large herbivores frequently display divergent migratory strategies, a likely consequence of the trade-off between the costs and benefits of migration. Globally, physical and environmental barriers disrupt ... -
Water use practices, water quality, and households' diarrheal encounters in communities along the Boro-Thamalakane-Boteti river system, Northern Botswana
(BioMed Central; https://jhpn.biomedcentral.com, 2015-11-18)Abstract Background: Some rural African communities residing along rivers use the untreated river water for domestic purposes, making them vulnerable to waterborne diseases such as diarrhea. Methods: We determined water ... -
The role of vegetation in the Okavango Delta silica sink
(Springer Link; https://link.springer.com, 2014-12-16)We assessed the role of vegetation and hydrology in the Si cycle in the Okavango Delta. Our results show a large storage of biogenic Si (BSi) in vegetation and the sediments. The biological storage is among the highest ... -
Ecotourism in Botswana: 30 years later
(Tailor and Francis Online; https://www.tandfonline.com, 2015-08-10)Thirty years ago, conservationists, host communities, academics, and tourism practitioners perceived ecotourism as a panacea to conservation and poverty problems in tourism destination areas, especially in developing ... -
Water quality dynamics in the Boro-Thamalakane-Boteti river system, northern Botswana
(Tailor and Francis Online; https://www.tandfonline.com, 2014-11-11)The quality of water in aquatic systems is subject to temporal and spatial variations due to varying effects of natural and anthropogenic factors. This study assessed the dynamics of water ... -
Flood variation and soil nutrient content in floodplain vegetation communities in the Okavango Delta
(South African Journal of Science; http://www.scielo.org.za, 2014-02)We investigated the influence of hydroperiod variation on soil nutrient content in the Okavango Delta seasonal floodplains. Soil samples were collected from eight zones of homogenous vegetation cover after low and high ... -
Herbivore size matters for productivity-richness relationships in African savannas
(British Ecological Society, https://www.britishecologicalsociety.org/, 2017-05)Productivity and herbivory often interact to shape plant community composition and species richness with levels of production mediating the impact of herbivory. However, differences in herbivore traits such as size, feeding ... -
Interactions between flooding and upland disturbance drives species diversity in large river floodplains
(Springer International Publishing Switzerland, 2016-02-10)Understanding and predicting vegetation patterns in floodplains are essential for conservation and/or restoration of river floodplains subject to hydrological alterations. We propose a conceptual hydroecological model to ... -
Fire frequency drives habitat selection by a diverse herbivore guild impacting top–down control of plant communities in an African savanna
(Nordic Society Oikos, www.nordicsocietyoikos.org/, 2016)In areas with diverse herbivore communities such as African savannas, the frequency of disturbance by fire may alter the top–down role of different herbivore species on plant community dynamics. In a seven year experiment ... -
Tree–grass competition along a catenal gradient in a mesic grassland, South Africa
(Wiley Online Library; https://onlinelibrary.wiley.com, 2014-03-03)The interaction, both above and belowground, between tree saplings and the surrounding grass sward is dependent on solar radiation, temperature, rainfall, soil depth, tree species and sward composition. These factors, ... -
Classical fisheries theory and inland (floodplain) fisheries management; is there need for a paradigm shift? lessons from the Okavango Delta, Botswana
(Fisheries and Aquaculture Journal; https://www.omicsonline.org, 2014-07-29)This paper reviews the fisheries management question of inland (floodplain) systems in the developing world and proposes a paradigm shift in approach. Inland fisheries management is largely based on classical fisheries ... -
Soil microbial biomass carbon, nitrogen and sulphur as affected by different land uses in Seronga, Okavango Delta, Botswana
(Sciencedomain international; www.sciencedomain.org, 2014-02-06)Aim: The Okavango Delta at Seronga is fragmented into different land uses ranging from grasslands to woodland (Ximenia and mopane), often punctuated with cropped and fallow fields. The influence of land uses on surface (A1 ... -
Influence of flooding variation on Molapo farming field size in the Okavango Delta, Botswana
(International Journal of Agricultural Research and Review; http://www.springjournals.net/ijarr, 2014-02)In the Okavango Delta of Botswana, flood recession farming (molapo farming) contributes substantially to rural livelihoods by providing better yields than rain-fed dry land farming. However, molapo farming communities ... -
Analysis of the economic benefits of tourism industry in contra-distinction to agricultural sector in rural Boteti, Botswana
(Canadian Center of Science and Education, www.ccsenet.org/, 2016-07-30)Despite numerous efforts to improve agricultural production as an alternative source of employment, the high poverty headcount is still a source for concern in rural Boteti. On average, agriculture contributes to less than ... -
Behaviour-related scalar habitat use by Cape Buffalo (Syncerus caffer caffer)
(Plos One, https://journals.plos.org/plosone/, 2015-12-16)Studies of habitat use by animals must consider behavioural resource requirements at different scales, which could influence the functional value of different sites. Using Cape buffalo (Syncerus caffer caffer) in the ... -
