(Oxford University Press, https://academic.oup.com, 2021-01-16)We compared diets of marabou storks Leptoptilos crumenifer foraging from urban landfills and natural areas in northern Botswana using stable isotope analyses and inductively coupled plasma mass spectrometry on moulted ... -
Trace metal enrichments in water of the Okavango Delta (Botswana): hydrological consequences
(Wiley Open Access, https://agupubs.onlinelibrary.wiley.com, 2021-05-03)he Okavango Delta in northern Botswana is an endorheic ecosystem formed by 150,000 islands surrounded by a flood plain. The vegetation of these islands displays an external tree ring enclosing a barren interior domain with ... -
Low oxygen: A (tough) way of life for Okavango fishes
(Public Library of Science, http://www.plosone.org/, 2020-07-30)Botswana’s Okavango Delta is a World Heritage Site and biodiverse wilderness. In 2016–2018, following arrival of the annual flood of rainwater from Angola’s highlands, and using continuous oxygen logging, we documented ... -
Physicochemical controls of diffusive methane fluxes in the Okavango Delta, Botswana
(Springer Link, https://link.springer.com, 2015-01-29)Atmospheric methane (CH4) is one of the three key greenhouse gases (GHGs) driving global climate change. The atmospheric concentration of CH4 has increased by about 150 % above pre-industrial levels of 400–700 ppb due to ... -
Consumer attitudes towards credit reference bureaus in Botswana: the effects of financial literacy, experience with credit reference bureaus and personal values
(University of Botswana, www.ub.bw, 2015-05)The aim of this study is to investigate consumer attitudes towards Credit Reference Bureaus and how financial literacy, experience with credit reference bureaus and personal values shape those attitudes. Using a survey, ... -
