Cryptic indicators of provenance from the geochemistry of the Okavango Delta sediments, Botswana
(Elsevier; http://www.elsevier.com/wps/find/journaldescription.cws_home/503361/description#description, 2005)
[Please note that chemical formulae do not display properly]:The siliciclastic sediments of the Okavango inland Delta of northwest Botswana have a modal composition of quartz arenites and result from a complex history, ...
Indicators of desiccation-driven change in the distal Okavango Delta, Botswana
(Elsevier Ltd; www.elsevier.com/locate/jaridenv, 2007-01)
This work seeks to determine whether riparian woody plant variables respond to drying and salinity regimes in the semi-arid distal Okavango Delta, northern Botswana. Structural and compositional variables were obtained ...
Use of the geochemical and biological sedimentary record in establishing palaeo-environments and climate change in the Lake Ngami basin, NW Botswana
(Elsevier; http://www.elsevier.com/wps/find/journaldescription.cws_home/865/description#description, 2007-02-07)
[Please note chemical formulae do not display correctly in this abstract]. Sediment samples from a continuous 4.6m profile in the dry bed of Lake Ngami in NW Botswana were analysed for geochemistry and dated using both 14C ...
Vegetation cover trends along the Botswana Kalahari transect
(Elsevier; www.elsevier.com/locate/jaridenv, 2003)
Vegetative response aspects of climate change studies include the determination of vegetation cover changes across climatic gradients. Vegetation characteristics and soil moisture measurements were obtained from four ...
Use of remotely sensed data in the analysis of soil-vegetation changes along a drying gradient peripheral to the Okavango Delta, Botswana
(Taylor & Francis; http://www.tandf.co.uk/journals/titles/01431161.asp, 2005-10-10)
This work determines the value of remotely sensed imagery in developing drying impacts which occur as a result of internal and/or external factors in the Okavango catchment. Three sites provide a preview of the consequences ...
