Capacity building for whole genome sequencing of Mycobacterium tuberculosis and bioinformatics in high TB burden countries
(Oxford University Press, 2020)Background Whole-genome sequencing (WGS) is increasingly used for Mycobacterium tuberculosis (Mtb) research. Countries with the highest tuberculosis (TB) burden face important challenges to integrate WGS into surveillance ... -
Analyzing chemical data in more than two dimensions: A tutorial on factor and cluster analysis
(Journal of chemical education, 1990)This tutorial is intended to introduce factor and cluster analysis at a level that will afford a senior student-and the practicing chemist, for that matter-some insights into the workings of the computer packages employing ... -
Topography-derived variables provide insight into habitat occupancy of a cryptic snake, Bitis atropos
(Wiley, 2021)Understanding species’ habitat use is fundamental for conservation and management. However, quantifying habitat use for small cryptic species is limited by imperfect detection during field surveys and the lack of habitat ... -
Wildlife- friendly livestock management promotes mammalian biodiversity recovery on a semi-arid Karoo farm in South Africa
(Frontiers Media, 2021)Agriculture is an essential production system used to feed the growing human population, but at the same time has become a major driver of biodiversity loss and environmental degradation. Employing production methods that ... -
Variation and change of upwelling dynamics detected in the world's eastern boundary upwelling systems
(Frontiers Media, 2021)Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of ... -
Transfer of Madagascan species of Gnidia L. to Lasiosiphon Fresen. (Thymelaeaceae: Thymelaeoideae)
(South African Journal of Botany, 2017)Thirteen of the fourteen Malagasy species of Gnidia are transferred to Lasiosiphon following its re-instatement based on systematic studies of the Thymelaeoideae. New combinations are made for five of the species and the ... -
