Herbaceous responses to herbivory, fire and rainfall variability differ between grasses and forbs
(Elsevier, 2018)Herbivory and fire are known to shape plant community structure and function in savanna ecosystems worldwide, yet these drivers are increasingly being altered in their behaviour, or completely excluded. Furthermore, ... -
Long-term water quality patterns of a flow regulated tropical lowland river
(MDPI, 2020)Floodplain ecosystems in Africa are under threat due to direct anthropogenic pressure and climate change. The lower Phongolo River and associated floodplain is South Africa’s largest inland floodplain ecosystem and has ... -
Opportunistic survival strategy of Welwitschia mirabilis : recent anatomical and ecophysiological studies elucidating stomatal behaviour and photosynthetic potential
(Canadian Science Publishing, 2017)We present new findings on leaf and stomatal apparatus anatomy and ecophysiology of Welwitschia mirabilis Hook.f. that are relevant to survival in the desert. We show that the structure of the stomatal apparatus with ... -
Photosynthetic responses of canola and wheat to elevated levels of CO2, O3 and water deficit in open-top chambers
(MDPI, 2019)The effects of elevated CO2 (700 ppm) and O3 (80 ppb) alone and in combination on the photosynthetic efficiency of canola and wheat plants were investigated in open-top chambers (OTCs). The plants were fumigated for four ...
