Kirkia Acuminata
''Kirkia'' is a genus of plant in family Kirkiaceae. It was previously placed in family Simaroubaceae, but was transferred into Kirkiaceae, together with '' Pleiokirkia'', because these genera produce neither quassinoids nor limonoids.

Acacia Afra
''Senegalia afra'', also known as hook-thorn or ''Acacia afra'', is a tree that occurs commonly in southern Africa. Though it is cultivated, it often occurs naturally in Gauteng suburban gardens, together with '' Acacia karroo'' and ''Acacia robusta''. It is up to tall and may be found in open woodland, grassland, rocky hillsides or watercourses. Description It has extremely hard, dense and attractive timber, and is only spared from intense exploitation because of its strongly twisted trunk which does not lend itself to long planks, and its tendency to develop heart rot. The bark is rough, dark grey and flaking, while the strong, paired hooked thorns are a formidable deterrent on young plants. Twigs which may vary in hairiness from densely puberulous to pubescent or tomentose. Due to its variability the species has been described under many names, some being listed below. ''Senegalia afra'' is deciduous and older plants are resistant to frost, fire and drought. Its appearance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veld
Veld ( or , Afrikaans language, Afrikaans and Dutch language, Dutch: ''veld'', field), also spelled veldt, is a type of wide-open, rural landscape in Southern Africa. Particularly, it is a flat area covered in grass or low scrubland, scrub, especially in the countries of South Africa, Namibia, Lesotho, Eswatini, Zimbabwe, and Botswana. A certain subtropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. Trees are not abundant; frost, fire, and grazing animals allow grass to grow, but prevent the build-up of dense foliage. Etymology The word ''veld'' () comes from the Afrikaans language, Afrikaans word for "field". The etymological origin is older modern Dutch language, Dutch ''veldt'', a spelling that the History of Dutch orthography, Dutch abandoned in favour of ''veld'' during the 19th century, decades before the first Afrikaans dictionary.Eric Anderson Walker (ed).

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

Dominance (ecology)
Ecological dominance is the degree to which one or several species have a major influence controlling the other species in their Community (ecology), ecological community (because of their large size, population, productivity, or related factors) or make up more of the Biomass (ecology), biomass. Both the composition and abundance of species within an ecosystem can be affected by the dominant species present. In most of the world's ecosystems, biologists have repeatedly observed a Rank abundance curve, rank-abundance curve in which ecosystems comprise a handful of incredibly abundant species, but more numerous, rarer species that are few in number. Danish botanist Christen C. Raunkiær described this phenomenon as his "Occupancy frequency distribution, law of frequency" in 1918, in which he recognized that in communities with a single species accounting for most of the biomass, species diversity was often lower. Understandably, biologists expect to see more profound effects fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...
