The effect of purified condensed tannins of forage plants from Botswana on the free-living stages of gastrointestinal nematode parasites of livestock.
(Elsevier, 2013-10-18)The effect of condensed tannins (CT) extracted from forage plants from Botswana on the free-living stages of a number of species of gastrointestinal nematode parasites derived from infected sheep were investigated using ... -
Assessment of γ-radiation levels and associated dose rates from surface soils in the eastern part of Botswana
(INDERSCIENCE Publishers, 2014)This paper reports the γ-radiation levels of the naturally occurring 40K, 210Pb, 232Th and 226Ra and the anthropogenic 137Cs in the eastern part of Botswana so as to assess their possible dose impact to the members of the ... -
Ethnozoological Survey of the Indigenous Knowledge on the Use of Pangolins (Manis Sps) in Traditional Medicine in Lentsweletau Extended Area in Botswana.
(Researchgate, 2014-06-30)Animals have played an important role in human life from prehistory. Many animals are used in zootherapy worldwide. However, the zootherapeutic practices by some communities are not well documented and may be forgotten. ... -
Evaluation of three breeding cycles for seedling weight of switchgrass, big bluestem, and indiangrass.
(Crop Science Society of America, 2014-07-01)A modified form of restricted, recurrent phenotypic selection was used to select for seedling shoot weight in switchgrass (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), and indiangrass [Sorghastrum nutans ... -
Seed dispersal by serrated tortoises (Psammobates Oculiferus) and the effect of their gut passage on seed germination.
(Researchgate, 2014-10-27)Some tortoises are frugivores and can disperse seeds away from the parent plant to areas favourable for their establishments through gut passage. We investigated the plant species dispersed by the serrated tortoise ... -
Health risk assessment of heavy metals via dietary intake of vegetables irrigated with treated wastewater around Gaborone, Botswana
(International Conference on Plant, Marine and Environmental Sciences, 2015-01)Heavy metal concentrations of Cd, Cr, Cu, Ni, Pb and Zn in green peppers (Capsicum annuum) and tomatoes (Solanum lycopersicum) irrigated with treated wastewater from the Glen Valley farms were determined. Concentrations ... -
