The effect of urbanization and agriculture on predacious arthropod diversity in the Highveld grasslands
(2015)Biodiversity provides vital ecosystem services and more diverse ecosystems are known to be more stable and resilient in the face of disturbance. Predacious arthropods provide a valuable ecosystem service to control pest ... -
Effects of Bt crop residues on the development, growth, and reproduction of the freshwater snail, Bulinus tropicus
(North-West University, 2014)Genetically modified (GM) crops were introduced in South Africa in 1989 and commercially available by 1998. Legislation to control the use of GM crops was only implemented in 1999, with the genetically modified organisms ... -
