Abstract:
Two new species of Romulea are described from Northern Cape, raising the number of species in southern Africa to 76. R. collina J.C.Manning Goldblatl is endemic to the Hantamsberg near Calvinia. It is distinguished in subgenus Spatalanthus by its clumped habit, yellow flowers with dark markings in the throat, and short papery bracts. A re-examination of rela­tionships within the subgenus suggests that section Cruciatae is not monophyletic and it is accordingly no longer recog­nized as separate from section Spatalanthus. R. eburnea J.C.Manning Goldblatt is a distinctive species of subgenus Spat

AbstractThe South African Astronomical Observatory (SAAO) observing station near Sutherland, Northern Cape in South Africa, is one of the darkest sites in the world for optical and IR astronomy. The SAAO hosts and operates several facilities, including the Southern African Large Telescope (SALT) and a number of international robotic telescopes. To ensure that the conditions remain optimal for astronomy, legislation called the Astronomy Geographic Advantage (AGA) Act, of 2007, was enacted. The Act empowers the Department of Science and Technology (DST) to regulate issues that pose a threat to o

Abstract:
Extracts of Sutherlandia frutescens (cancer bush) exhibit considerable qualitative and quantitative chemical variability depending on their natural wild origins. The purpose of this study was thus to determine bioactivity of extracts from different regions using in vitro antioxidant and anti-cancer assays. Extracts of the species are complex and are predominantly composed of a species-specific set of triterpene saponins (cycloartanol glycosides), the sutherlandiosides, and flavonoids (quercetin and kaempferol glycosides), the sutherlandins.

Abstract:
Sprites are the optical signatures of electrical discharges in the mesosphere triggered by large lightning strikes associated with thunderstorms. Since their discovery in the late 1980s, sprites have been observed extensively around the world, although very few observations of sprites from Africa have been documented in the literature. In this paper, we report the first ground-based recorded observations of sprites from South Africa. In 2 out of the 22 nights of observations (11 January and 2 February 2016), about 100 sprite elements were recorded from Sutherland in the Northern Cape, comprisi

Abstract:
Sprites are mesospheric optical emissions that are mostly produced by large, positive cloud-to-ground lightning discharges. Sprites appear in different morphologies such as carrot, jellyfish and column, and are typically in the altitude range of ~40–100 km above the Earth’s surface. Sprites are a subset of transient luminous events and they contribute to the global electric circuit. South Africa has large convective thunderstorms, which typically occur in the summer months of every year. Peak current, time and geographical position of lightning strokes were obtained from the South African Weat

What does counterculture do? This is the question we asked ourselves repeatedly in curating this issue for M/C Journal. While incredible examples of countercultural lives—collective and individual—were described in articles we received, what we have tried to do is bring together research on how counterculture is both theorised and practised in local and international contexts. At the heart of this issue is a two-day conference in May 2013 titled “Aquarius and Beyond: 40 years on…” (Southern Cross University) that marked the 40th anniversary of the 1973 Nimbin Aquarius Festival, held in the nor

Abstract:
The Saltpeterkop Carbonatite Complex is a Late Cretaceous (≈76 Ma) volcanic and shallow intrusive magmatic feature located approximately 20 km southeast of Sutherland in the Northern Cape. It is unusual among southern African carbonatite complexes in that it has not been deeply eroded, and retains a significant vestige of its original volcanic features. The main geologic expression of the Complex is a ≈1.5 km diameter tuff ring, located on top of prominently updomed and fractured Beaufort Group (Karoo) sediments, that appears to have formed as the result of a major diatreme-type eruption.

The clinopyroxene, amphibole, phlogopite and ilmenite megacrysts all appear to be cogenetic, and based on known mineral relationships and intergrowths from xenoliths in the complex, the apparent order of mineral crystallisation is as follows: phlogopite → ilmenite → amphibole → clinopyroxene. Megacrysts of amphibole and phlogopite exhibit δD and δ18O values that are aligned with these grains having crystall

Post 2005, the largest optical telescope in the Southern hemisphere, known by its acronym, SALT, was constructed in RSA. It is expected that by 2024, this country will host the largest array of radio telescopes in the world, the Square Kilometre Array (SKA). It could be argued that RSA is at the forefront of modern cosmological research. This exponential growth in the field of astronomy has resulted in local astronomical bodies and un

Abstract:
Enough mammal specimens of Late Glacial date from the British Isles have been subjected to radiocarbon dating to provide a reliable outline of the likely large mammal fauna of the time, though the accompanying fauna of small mammals has mostly been assigned to this period on associative, rather than direct, dating. These give an adequate zoological background against which to examine the suggested identities of the large mammals depicted at Church Hole, Creswell Crags. This background information is reviewed in this chapter. While Bison priscus was certainly present earlier in the Devensian, there is no evidence that Bison returned to Britain in the Late Glacial, but aurochs (Bos primigenius) did so, and must be considered a more probable identification. The evidence that ibex (Capra ibex) ever occurred in Britain is very dubious, which cast serious doubt on the original identification of the Church Hole Panel III engraving as being of this species. In this case, discussion and reinterpretation of the engravings during the course of the conference suggested a better resolution than the zoological one suggested at the time. The ice of the Devensian glacial maximum, at about 20–18 ka BP, is believed to have covered all of northern Great Britain and Ireland, leaving smaller areas of the south of each island free of ice but occupied by tundra, permafrost, conditions. It is most unlikely that any of the present mammal fauna could have survived here then, though the possibilities that mountain hare (Lepus timidus) and stoat (Mustela erminea) did so must be conceded—both range well into the Arctic at the present day. The severity of the climate, and the likely nature of the mammal fauna, is indicated by the presence of musk ox (Ovibos moschatus) (Fisherton, Wiltshire, but undated) and the possible polar bear (Ursus maritimus) (Creag nan Uamh, Sutherland, 18.9 ka: Kitchener and Bonsall 1997) that date to this time. Barnwell Station, Cambridge, has a&lt;sup&gt;14&lt;/sup&gt; C date on peat of 19.5 ka BP, and a fauna including woolly mammoth (Mammuthus primigenius), woolly rhinoceros (Coelodonta antiquitatis), reindeer (Rangifer tarandus), and horse (Equus ferus). Dated specimens fromsouthern Ireland are also relevant: collared lemming (Dicrostonyx torquatus) at20.3 ka BP, woolly mammoth at 20.36 ka BP and Arctic fox (Alopex lagopus) at 19.95 ka BP, all from Castlepook Cave, Cork (Woodman et al. 1997).
