Abiotic and biotic factors influencing the mobility of arsenic in groundwater of a through-flow island in the Okavango Delta, Botswana
Mladenov, Natalie; Wolski, Piotr; Hettiarachchi, Ganga M.; Murray-Hudson, Michael; Enriquez, Hersy; Damaraju, Sivaramakrishna; Galkaduwa, Madhubhashini B.; McKnight, Diane M.; Masamba, Wellington (Elsevier, https://www.elsevier.com, 2014-10-10)The Okavango Delta of Botswana is a large arid-zone wetland comprising 20,000 km2 of permanent and seasonal floodplains and over 100,000 islands. It has been shown that island groundwater can have very high dissolved arsenic ... -
Biomass production and economic value of Phragmites australis reedbeds in the Southern Okavango Delta, Botswana
Murray-Hudson, Michael; Mmopelwa, Gagoitseope (Global Science Books, www.globalsciencebooks.info, 2010-11-10)Most work globally on Phragmites spp. has been done in temperate northern hemisphere localities, where winter low temperatures and short day lengths cause a seasonal decrease in growth. In this study, we report above-ground ... -
Disaggregating hydroperiod: components of the seasonal flood pulse as drivers of plant species disribution in floodplains of a tropical wetland
Murray-Hudson, Michael; Wolski, Piotr; Murray-Hudson, Frances; Brown, Mark T.; Kashe, Keotshephile (Springer Link, http://link.springer.com/article/10.1007/s13157-014-0554-x#, 2014-06-22)Wetland hydroperiod consists of different components, including frequency, duration and depth. A significant proportion of the seasonally flood-pulsed Okavango Delta is inundated for part of each year. Variation in ... -
Interactions between flooding and upland disturbance drives species diversity in large river floodplains
Murray-Hudson, Michael; Arias, Mauricio, E.; Wittmann, Florian; Parolin, Pia; Chochrane, Thomas, A. (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 ... -
Phenology is the dominant control of methane emissions in a tropical non-forested wetland
Hefter, Carol; Gondwe, Mangaliso; Murray-Hudson, Michael; Makati, Anastacia; Lunt, Mark F.; Palmer, Paul, I.; Skiba, Ute (Springer Nature, https://www.springernature.com, 2022-01-10)Tropical wetlands are a significant source of atmospheric methane (CH4), but their importance to the global CH4 budget is uncertain due to a paucity of direct observations. Net wetland emissions result from complex ... -
The population structure of riparian tree species in the Okavango Delta, Botswana: 50 years of independence and conservation
Tsheboeng, Gaolathe; Murray-Hudson, Michael; Kashe, Keotshephile (Botswana Notes and Records; http://journals.ub.bw/index.php/bnr/, 2017-07-05)Riparian woodlands in the Okavango Delta play a significant role of removing salts from surface water through transpiration. This function renders surface water healthy to drink by wildlife and the people. Despite their ... -
Post-fire succession on savanna habitats in the Okavango Delta wetland, Botswana
Heinl, Michael; Murray-Hudson, Michael; Tacheba, Buzanani (Cambridge University Press, https://www.cambridge.org/, 2007-10-29)Drying floodplains that were not inundated for more than 10 y were investigated to relate plant species and vegetation structure to time-since-fire for the southern Okavango Delta wetland in Botswana. The aims of the ... -
A review of the freshwater diversity in the Okavango Delta and Lake Ngami 1 (Botswana): taxonomic composition, ecology, comparison with similar 2 systems and conservation status
Makati, Kaelo; Chadwick, Michael A.; Catford, Jane A.; Price, Benjamin W.; Mackay, Anson W.; Guiry, Michael D.; Murray-Hudson, Michael; Murray-Hudson, Frances; Moliner Cachazo, Luis (Springer Link, https://www.springer.com/journal/27/, 2023-10-11)Freshwater organisms in the Okavango Delta and Lake Ngami (Botswana) provide direct and indirect benefits to people and the economy of the region. However, their existence could be potentially threatened by human activities ... -
Species richness, diversity, density and spatial distribution of soil seed banks in the riparian woodland along the Thamalakane River of the Okavango Delta, northern Botswana
Mmusi, Mmusi; Tsheboeng, Gaolathe; Teketay, Demel; Murray-Hudson, Michael; Kashe, Keotshephile; Madome, Joseph (Elservier, https://www.elsevier.com, 2021-12)Soil seed banks serve as reservoirs of seeds for subsequent regeneration of plants. Soil seed banks were investigated along the Thamalakane Riparian Woodlands (hereafter referred to as TRWs) of the Okavango Delta, northern ... -
Water balance and variations of nutrients and major solutes along a river transect through the Okavango Delta, Botswana
Gondwe, Mangaliso J.; Masamba, Wellington R.L.; Murray-Hudson, Michael (Botswana Notes and Records; http://journals.ub.bw/index.php/bnr/, 2017-07-05)Wetland goods and services provide a means of survival for many riparian rural communities in developing countries, particularly in the Sub-Saharan Africa. To sustain the provision of goods and services for human use, ...
