Foliar nitrogen dynamics of an invasive legume compared to native non-legumes in fynbos riparian zones varying in water availability
(Creative Commons Attribution License, 2019)
The legume Acacia mearnsii invades South Africa’s fynbos riparian zones and may alter the nitrogen (N) dynamics and supply in these areas that typically support few native N fixers. Nitrogen uptake by A. mearnsii may also ...
Alien bamboos in South Africa: a socio-historical perspective
Changes in fashions and economic imperatives underlying plant introductions have a profound influence on the movement of species around the world. Using bamboo introductions into South Africa as a case-study, we explore ...
Non-invasive monitoring of adrenocortical activity in free-ranging Namaqua rock mice Micaelamys namaquensis from South Africa in response to anthropogenic land use and season
Stress in animals has been linked to behavioural and physiological changes in response to environmental, social and anthropogenic stimuli. Hence, stress-related responses in animals, especially in rodents, have been used ...
A successful biocontrol agent in the USA, Diorhabda carinulata (Coleoptera: Chrysomelidae) on Tamarix spp. (Tamaricaceae), rejected in South Africa due to insufficient host specificity
Several countries globally, including South Africa, have been invaded by at least one of five species of Tamarix. South Africa therefore considered using one or more species of leaf-feeding beetles in the genus Diorhabda ...
The absence of keystone indigenous trees inhibits bird recovery up to a decade after invasive tree removal from riparian habitats
When invasive alien trees are removed, ecosystems are usually left to “self-repair”. Little is known about the extent of recovery or whether plant and animal taxa respond in a similar way. In most cases, the absence of a ...
