  • Water-use dynamics of an alien-invaded riparian forest within the summer rainfall zone of South Africa 
    Scott-Shaw, Bruce C.; Everson, Colin Stuart (Copernicus Publications on behalf of the European Geosciences Union, 2019-03-18)
    In South Africa the invasion of riparian forests by alien trees has the potential to affect the country’s limited water resources. Tree water-use measurements have therefore become an important component of recent ...

    Botha, Monique; Archibald, Sally; Greve, Michelle (Wiley Open Access, 2020-10)
    1. Fire and frost represent two major hurdles for the persistence of trees in open grassy biomes and have both been proposed as drivers of grassland-forest boundaries in Africa. 2. We assess the response of young tree ...
  • What is in a name? Scientific name changes of potentially poisonous plants and fungi in South Africa 
    Botha, C.J. (Christoffel Jacobus); Van Wyk, Abraham Erasmus (Braam) (Medpharm Publications, 2022)
    Changes over the past five decades in the scientific names of some potentially poisonous plants and toxigenic fungi in South Africa are briefly reviewed. Some of the reasons why taxonomists change names are highlighted. ...
  • Wheat line “RYNO3936” is associated with delayed water stress-induced leaf senescence and rapid water-deficit stress recovery

    Random mutagenesis was applied to produce a new wheat mutant (RYNO3926) with superior characteristics regarding tolerance to water deficit stress induced at late booting stage. The mutant also displays rapid recovery ...
  • Whole genome sequencing of extended-spectrum- and AmpC- beta-lactamase-positive enterobacterales isolated from spinach production in Gauteng Province, South Africa 
    Richter, Loandi; Du Plessis, Erika Margarete; Duvenage, Stacey; Allam, Mushal; Ismail, Arshad; Korsten, Lise (Frontiers Media, 2021-10-01)
    The increasing occurrence of multidrug-resistant (MDR) extended-spectrum β-lactamase- (ESBL) and/or AmpC β-lactamase- (AmpC) producing Enterobacterales in irrigation water and associated irrigated fresh produce represents ...
  • Why herbicides are most effective on young weeds 
    Reinhardt, Carl Frederick (Charlie) (Plaas Publishing, 2019-01)
    Weeds are wonderous creations of nature – weedy type plants not only survived but over time have evolved miraculous adaptations to all the control methods we humans have exposed them to. Our battle against weeds has seen ...
  • Wicked' US weed has put down roots locally 
    Reinhardt, Carl Frederick (Charlie) (Plaas Publishing, 2018-09)
    The term ‘wicked’ weed is borrowed from the field of sociology where a wicked problem is defined as one without clear causes or solutions, and thus difficult or impossible to solve (Shaw, 2016, Weed Science: Special Issue, ...
  • Willingness-to-pay for environmental services provided by trees in core and fringe areas of Benin City, Nigeria 
    Arabomen, O.J.; Chirwa, Paxie W.; Babalola, Folaranmi Dapo (Commonwealth Forestry Association, 2019-03-15)
    Economic valuation of environmental services has emerged as a new and more direct argument and incentive for protection of trees and sustenance of environmental quality. This study's aim was to estimate the monetary value ...
