Many of these basins can be considered to have formed as a response to reactivation along lineaments, which had initially formed by accretion processes during the amalgamation of the craton Keywords: Kaapvaal during the Mid-Archaean. Faulting along these lineaments controlled sedimentation either directly by Witwatersrand controlling the basin margins, or indirectly by controlling the sediment source areas.

Sequence Stratigraphic Development of the Neoarchean Transvaal Carbonate Platform, Kaapvaal Craton, South Africa Dawn Y
DAWN Y. SUMNER AND NICOLAS J. BEUKES 11 Sequence Stratigraphic Development of the Neoarchean Transvaal carbonate platform, Kaapvaal Craton, South Africa Dawn Y. Sumner Department of Geology, University of California 1 Shields Ave, Davis, CA 95616 USA e-mail: [email protected] Nicolas J. Beukes Department of Geology, University of Johannesburg P.O. Box 524, Auckland Park, 2000 South Africa e-mail: [email protected] © 2006 March Geological Society of South Africa ABSTRACT The ~2.67 to ~2.46 Ga lower Transvaal Supergroup, South Africa, consists of a mixed siliciclastic-carbonate ramp that grades upward into an extensive carbonate platform, overlain by deep subtidal banded iron-formation. It is composed of 14 third-order sequences that develop from a mixed siliciclastic-carbonate ramp to a steepened margin followed by a rimmed margin that separated lagoonal environments from the open ocean. Drowning of the platform coincided with deposition of banded iron-formation across the Kaapvaal Craton. The geometry and stacking of these sequences are consistent with more recent patterns of carbonate accumulation, demonstrating that Neoarchean carbonate accumulation responded to subsidence, sea level change, and carbonate production similarly to Proterozoic and Phanerozoic platforms. The similarity of carbonate platform geometry through time, even with significant changes in dominant biota, demonstrates that rimmed margins are localized primarily by physiochemical conditions rather than growth dynamics of specific organisms. Stratigraphic patterns during deposition of the Schmidtsdrift and Campbellrand-Malmani subgroups are most consistent with variable thinning of the Kaapvaal Craton during extrusion of the ~2.7 Ga Ventersdorp lavas. Although depositional patterns are consistent with rifting of the western margin of the Kaapvaal Craton during this time, a rift-to-drift transition is not required to explain subsidence. -

Schweickerdt Herbarium, Department of Plant and Soil Sciences, University of Pretoria, Pretoria, 0002 South Africa. *Author for correspondence. E-mail: [email protected] Abstract Gymnosporia sekhukhuniensis, a new species from north-eastern South Africa, is described, illustrated, mapped, and compared with closely related species. It belongs to Gymnosporia sect. Buxifoliae, more specifically Group 1, the members of which are characterized by the capsules being (2)3(4)-valved, rugose or verrucose, and the seeds partially covered by the aril. The new species has a restricted distribution range and is near-endemic to the Sekhukhuneland Centre of Endemism. This biogeographical region rich in restricted-range plants is more or less congruent with surface outcrops of mafic and ultramafic igneous rocks belonging to the Rustenburg Layered Suite of the eastern Bushveld Complex. The range of the new species shows marginal intrusion into the far northern part of the nearby Wolkberg Centre of Endemism, where it is associated with dolomites of the Malmani Subgroup. Gymnosporia sekhukhuniensis is a suffrutex mainly associated with rocky outcrops in open savannah. Diagnostic characters include its dwarf habit (up to 1.6 m tall), capsules that are relatively small (5–8 mm long), woody, scaly-rugose, with hard pointed apices, and leaves that are very laxly arranged on the stems, with some often present on the thorns. -
A Phylogeographic Survey of the Pygmy Mouse Mus Minutoides in South Africa: Taxonomic and Karyotypic Inference from Cytochrome B Sequences of Museum Specimens
A Phylogeographic Survey of the Pygmy Mouse Mus minutoides in South Africa: Taxonomic and Karyotypic Inference from Cytochrome b Sequences of Museum Specimens Pascale Chevret1*, Terence J. Robinson2, Julie Perez3, Fre´de´ric Veyrunes3, Janice Britton-Davidian3 1 Laboratoire de Biome´trie et Biologie Evolutive, UMR CNRS 5558, Universite´ Lyon 1, Villeurbanne, France, 2 Evolutionary Genomics Group, Department of Botany and Zoology, University of Stellenbosch, Stellenbosch, South Africa, 3 Institut des Sciences de l’Evolution de Montpellier, UMR CNRS 5554, Universite´ Montpellier 2, Montpellier, France Abstract The African pygmy mice (Mus, subgenus Nannomys) are a group of small-sized rodents that occur widely throughout sub- Saharan Africa. Chromosomal diversity within this group is extensive and numerous studies have shown the karyotype to be a useful taxonomic marker. This is pertinent to Mus minutoides populations in South Africa where two different cytotypes (2n = 34, 2n = 18) and a modification of the sex determination system (due to the presence of a Y chromosome in some females) have been recorded. This chromosomal diversity is mirrored by mitochondrial DNA sequences that unambiguously discriminate among the various pygmy mouse species and, importantly, the different M. minutoides cytotypes. However, the geographic delimitation and taxonomy of pygmy mice populations in South Africa is poorly understood. To address this, tissue samples of M. minutoides were taken and analysed from specimens housed in six South African museum collections. Partial cytochrome b sequences (400 pb) were successfully amplified from 44% of the 154 samples processed. Two species were identified: M. indutus and M. minutoides. The sequences of the M. indutus samples provided two unexpected features: i) nuclear copies of the cytochrome b gene were detected in many specimens, and ii) the range of this species was found to extend considerably further south than is presently understood. -

Chapter 15 the Mammals of Angola
Chapter 15 The Mammals of Angola Pedro Beja, Pedro Vaz Pinto, Luís Veríssimo, Elena Bersacola, Ezequiel Fabiano, Jorge M. Palmeirim, Ara Monadjem, Pedro Monterroso, Magdalena S. Svensson, and Peter John Taylor Abstract Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records. We present a short history of mammal research, and provide brief information on each species known to occur in the country. Particular attention is given to endemic and near endemic species. We also provide a zoogeographic outline and information on the conservation of Angolan mammals. We found confirmed records for 291 native species, most of which from the orders Rodentia (85), Chiroptera (73), Carnivora (39), and Cetartiodactyla (33). There is a large number of endemic and near endemic species, most of which are rodents or bats. The large diversity of species is favoured by the wide P.

It also serves as a compact record of your African journey for future reference that hopefully sparks interest in other wildlife spheres when you return home or when travelling elsewhere on our fragile planet. Although always exciting to see, especially for the first-time Africa visitor, once you move beyond the cliché of the ‘Big Five’ you will soon realise that our wilderness areas offer much more than certain flagship animal species. Africa’s large mammals are certainly a big attraction that one never tires of, but it’s often the smaller mammals, diverse birdlife and incredible reptiles that draw one back again and again for another unparalleled visit. Seeing a breeding herd of elephant for instance will always be special but there is a certain thrill in seeing a Lichtenstein’s hartebeest, cheetah or a Lilian’s lovebird – to name but a few. As a globally discerning traveller, look beyond the obvious, and challenge yourself to learn as much about all wildlife aspects and the ecosystems through which you will travel on your safari. -
