Experiments were conducted to evaluate the effects of combined water salinity and deficit irrigation on common bermudagrass in order to address the shortage of water…

Mutualism between plants and animals demonstrates that grazing has positive impacts on plant growth. Animal saliva plays an important role in plant–herbivore…

Abstract Stipa tenacissima L. (alpha grass) steppes are one of the most representative ecosystems in arid Mediterranean ecosystems. On the one hand these steppes, which…

Condensed tannins are ecologically important compounds in plants for several reasons, e.g. as herbivore deterrents or protecting photosynthetic tissues against ultraviolet…

This study assesses how climate impacts on agriculture may change the evolution of the agricultural and energy systems in meeting the end-of-century radiative forcing…

Annual burning homogenizes plant communities and causes a shift in species composition. Annual burning does not cause significant reductions in plant species richness…

Browsing herbivores are generally highly selective feeders, selecting for new shoots and young plant material. Determinations of browser carrying capacity are then greatly…

The main aim of this study was to examine how concentrations of the micronutrients cobalt, copper, iron, manganese, molybdenum, nickel and zinc change with phenological…

Global warming in response to accumulation of human-induced greenhouse gases inside the atmosphere has already caused several visible consequences, among them increase of…

Tropical and subtropical rangeland systems provide core ecosystem services for the welfare of human populations that rely on readiness and quality of forage resources.…

With the rapid expansion of wildlife ranching and conservation in South African savannas and the resultant increase in multi-species grazing and browsing systems,…

Research to study the effect of cover crop sowing rate, row spacing and cultivar on establishment of lucerne (Medicago sativa L.)-based pastures in a semi-arid zone mixed-…

The degree of dispersion of trait values among species in a community has frequently been used to infer processes of community assembly. However, multiple assembly…

Abstract The knowledge of relative performance of plants across environmental gradients is critical for their effective management and for understanding future range…

Land Type mapping units were used to stratify the Heritage Park corridor, in the North West province, South Africa, into eight Land Type units prior to placing 109…

As a textbook, the volume is well organised, with introductory chapters on the scope and key concepts of restoration ecology, followed by chapters on its ecological…

Climate change is expected to adversely affect agriculture in South Africa. A rise in variable and unfavourable conditions is likely to surpass the limits of current…

Stable global temperatures of the last 10–15 years have been a topic of considerable discussion. A new proxy extension of the global temperature record enables better…

Editorial

Currently, the methods used to assess the veld condition of the Lambert's Bay Strandveld along the West Coast of South Africa require that the operator knows all the…
