A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ... -
Functional heterogeneity of habitats and dry season forage variability in an Okavango Delta landscape, northern Botswana.
(Elsevier, 2021-08-27)The late dry season is a period when forage resources become limited in some African savannas that can induce a strong demographic bottleneck in herbivore populations with limited access to resource heterogeneity. This ... -
Fuzzy Modeling for the Dynamics of Alcohol-Related Health Risks with Changing Behaviors via Cultural Beliefs.
(HINDAWI, 2020-07-13)In this paper, we propose and analyze a fuzzy model for the health risk challenges associated with alcoholism. The fuzziness gets into the system by assuming uncertainty condition in the measure of influence of the risky ... -

Gender impact on sheep and soat production in Botswana. A case of Gaborone region
(Journal of Agriculture in the Tropics and Subtropics, 2001)A survey of 100 randomly selected farming households keeping livestock was conducted in ten randomly selected villages in the Gaborone agricultural region from October 1997 to February 1998. Data acquisition was done through ... -
Genetic characterization of tswana and tuli cattle kept at Botswana University of Agriculture and Natural Resources using microsatellite markers
(Botswana University of Agriculture and Natural Resources, 2020-10)Twelve FAO-lSAG-rccommended microsatellite markers were used to analyse genetic variation in Tswana and Tuli cattle breeds. All loci were polymorphic and a total of 75 and 77 alleles were genotyped in the Tswana and Tuli ... -
Genetic Polymorphism in the Promoter and 5 ́ UTR of HSP-70 Gene in Three Strains of Indigenous Tswana Chickens and Commercial Broilers
(Scienceline Publication, 2021-12-10)The current study was conducted to investigate sequence polymorphisms in the promoter, 5 ́untranslated regions (UTR), and partial exon regions of chicken HSP-70 gene in the normal (n = 24), naked neck (n = 22), and dwarf ... -
Genetic variation from 12 microsatellite makers in an indigenous Tswana goat flock in South-eastern Botswana
(Livestock Research for Rural Development, 2013)The objective of this study was to preliminary characterize genetic variability from 12 microsatellite markers in an indigenous Tswana goat flock in South-eastern Botswana. The genomic DNA from 87 partially pedigreed ... -
Genotypic variation in response to drought stress is associated with biochemical and transcriptional regulation of ureides metabolism in common bean (Phaseolus vulgaris L.).
(University of Ljubljana, 2022-05-29)Ureidic legumes such as common bean (Phaseoulus valgaris L.) plants export nitrogen from the nodules to shoots and leaves as ureides during symbiotic biological nitrogen fixation. Common bean gene encoding allantoinase ... -
