Influence of drone altitude, image overlap, and optical sensor resolution on multi-view reconstruction of forest images
(MDPI, 2019)Recent technical advances in drones make them increasingly relevant and important toolsfor forest measurements. However, information on how to optimally set flight parameters and choosesensor resolution is lagging behind ... -
Near infrared technology : getting the best out of light
(AFRICAN SUN MeDIA, 2019)Imagine an analytical technique that uses no chemicals, gives accurate and precise results in minutes or even continuously, and is simple to install and safe to use. Near-infrared spectroscopy (NIRS) supplies this dream. ... -
Morphological and molecular identification of fungi associated with South African apple core rot
(Springer, 2018)Core rot is a major contributor to postharvest losses in apples worldwide. Pathogens most commonly associated with the disease are Alternaria spp. and Penicillium spp. Although both genera show specific morphological ... -
Private rhino conservation : diverse strategies adopted in response to the poaching crisis
(Wiley Open Access, 2020)Private landowners in South Africa conserve roughly 40% of white rhinos globally. Given concerns that escalating poaching has caused private‐rhino owners to disinvest, we used a national survey to assess 171 private‐rhino ... -
Phylogeography, genetic diversity, and population structure of Nile crocodile populations at the fringes of the southern African distribution
(Public Library of Science, 2018)Nile crocodiles are apex predators widely distributed in sub-Saharan Africa that have been viewed and managed as a single species. A complex picture of broad and fine-scale phylogeographic patterns that includes the ... -
The complete mitochondrial genome and phylogenetic position of the leopard catshark, Poroderma pantherinum
(Taylor & Francis Open, 2018)We present the first mitochondrial genome of a South African endemic catshark, Poroderma pantherinum. The complete mitogenome is 16,686 bp in length, comprising 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and ... -
Modification of cassava root starch phosphorylation enhances starch functional properties
(Frontiers Media, 2018)Cassava (Manihot esculenta Crantz) is a root crop used as a foodstuff and as a starch source in industry. Starch functional properties are influenced by many structural features including the relative amounts of the two ... -
Repression of sex4 and like sex four2 orthologs in potato increases tuber starch bound phosphate with concomitant alterations in starch properties physical
(Frontiers Media, 2018-07-23)To examine the roles of starch phosphatases in potatoes, transgenic lines were produced where orthologs of SEX4 and LIKE SEX FOUR2 (LSF2) were repressed using RNAi constructs. Although repression of either SEX4 or LSF2 ... -
Plant immunity is compartmentalized and specialized in roots
(Frontiers Media, 2018)Roots are important organs for plant survival. In recent years, clear differences between roots and shoots in their respective plant defense strategies have been highlighted. Some putative gene markers of defense responses ... -
Impact of climate trends and drought events on the growth of oaks (Quercus robur L. and Quercus petraea (Matt.) Liebl.) within and beyond their natural range
(MDPI, 2018-02-28)ENGLISH ABSTRACT: Due to predicted climate change, it is important to know to what extent trees and forests will be impacted by chronic and episodic drought stress. As oaks play an important role in European forestry, this ... -
Geographic variation and plasticity in climate stress resistance among southern African populations of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae)
(Nature Research, 2018-06-29)Traits of thermal sensitivity or performance are typically the focus of species distribution modelling. Among-population trait variation, trait plasticity, population connectedness and the possible climatic covariation ... -
The impact of changes in environmental conditions on organic acid production by commercial wine yeast strains
(South African Society for Enology and Viticulture, 2018)Acidity is one of the primary sensory elements in wine, and the balance of sugar and acidity is probably the strongest element affecting wine appreciation. However, little is known about how yeast strains and fermentation ... -
The current status of indigenous ovine genetic resources in Southern Africa and future sustainable utilisation to improve livelihoods
(MDPI, 2019-12-25)Abstract: Indigenous sheep play an important role in the livelihoods of communal farmers in the Southern Africa Development Community (SADC), and this underlines the need to curb the genetic erosion of these valuable ... -
An investigation into shrinkage and collapse behaviour of Eucalyptus grandis and Eucalyptus grandis x urophylla wood
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Only 1 % of land is used for forestry in South Africa and the country might experience a shortage of structural softwood sawn timber in the near future. Despite this, South Africa actually produces more ... -
Modelling the effect of stand density management and environmental variables on Pinus patula wood properties
(Stellenbosch : Stellenbosch University, 2020-04)ENGLISH ABSTRACT: Approximately one million hectares of Pinus patula has been planted worldwide, mainly in southern and eastern Africa and accounts for roughly half of the total softwood plantation area in South Africa. ... -
Assessing the competitive performance of smallholder wool growers in the South African wool industry
(2020-03)ENGLISH ABSTRACT: The South African wool value chain has potential to increase its production levels from the current 50 million kg to 75 million kg per annum without negatively affecting the wool prices, according to De ... -
The impact of globalisation on food availability and access in developing countries : a case of Malawi
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH SUMMARY : Globalisation has affected food systems in the world and the world’s poor in so many ways. The increased process of globalisation has had a major impact on food security around the world and with it a ... -
The prevalence of Campylobacter and Arcobacter species in ostriches from South Africa
