The causes of the worldwide problem of encroachment of woody plants into grassy vegetation are elusive. The effects of soil nutrients on competition between herbaceous and woody plants in various landscapes are particularly poorly understood. A long-

The puzzling exclusion of native trees from grassland under mesic climates can hypothetically be explained by nutritional regimes that make grasses competitively superior to trees. One hypothesis holds that where nutrient concentrations in soils allo

The ultimate reasons for treelessness in the natural grassland of the Highveld of southern Africa have long eluded biologists. This is partly because of the ambivalence of adaptive determinism versus biogeographical/phylogenetic accidents, and partly

The influence of soil organisms on the availability of nutrients to other biota within ecosystems can be context-dependent. Fungus-culturing termites, for example, are known to concentrate nutrients by building large mounds in nutrient-poor savannas,

The scarcity of indigenous trees on the Highveld of eastern South Africa is usually attributed to frost, fire and drainage, regardless of whether the soils are nutrient-poor (sourveld grasslands) or nutrient-rich (sweetveld grasslands). However, soil

Aerosols play important roles in soil genesis and plant nutrition, at both local and intercontinental scales, by redistributing nutrients through the atmosphere. Aerosol capture by tree crowns is a possible mechanism by which trees significantly augm

Teachers may use apprenticeships and collaboration as instructional strategies that help students to make authentic scientific discoveries as they work as amateur researchers in academic field studies. This concept was examined with 643 students, age

The influence of soil nutrients on woody plants is poorly understood. Are trees – fire and other disturbance factors being equal – generally promoted by nutrient-rich or by nutrient-poor soils? To determine the edaphic parameters controlling wood

Although numerous hypotheses have been proposed to explain geophagy, the primary driver of this behaviour remains elusive. Supplementation of scarce nutrients is one commonly cited explanation. We examined the element concentration of three licks rel
