Léon Referent: Prof. Dr. Jens Léon Korreferent: Prof. Dr. Jaime Fagúndez Korreferent: Prof. Dr. Dietmar Quandt Tag der mündlichen Prüfung: 15.11.2013 Erscheinungsjahr: 2013 A mis flores Rolf y Florian Abstract Abstract With over 840 species Erica L. is one of the largest genera of the Ericaceae, comprising woody perennial plants that occur from Scandinavia to South Africa. According to previous studies, the northern species, present in Europe and the Mediterranean, form a paraphyletic, basal clade, and the southern species, present in South Africa, form a robust monophyletic group. In this work a molecular phylogenetic analysis from European and from Central and South African Erica species was performed using the chloroplast regions: trnL-trnL-trnF and 5´trnK-matK , as well as the nuclear DNA marker ITS, in order i) to state the monophyly of the northern and southern species, ii) to determine the phylogenetic relationships between the species and contrasting them with previous systematic research studies and iii) to compare the results provided from nuclear data and explore possible evolutionary patterns. All species were monophyletic except for the widely spread E. arborea , and E. manipuliflora . The paraphyly of the northern species was also confirmed, but three taxa from Central East Africa were polyphyletic, suggesting different episodes of colonization of this area. -

E-mail: [email protected] Abstract Putterlickia neglecta, a new species here described and illustrated, is known from South Africa (Mpumalanga and north- eastern KwaZulu-Natal), Swaziland and southern Mozambique. It is considered a near-endemic to the Maputaland Centre of Endemism. Plants grow as a shrub or small tree in savanna and thicket, or in the understory of inland, coastal and dune forests. Vegetatively it superficially resembles P. verrucosa, the species with which it has hitherto most often been confused. Both species have stems with prominently raised lenticels, but P. neglecta differs from P. verrucosa in having sessile to subsessile leaves with mostly entire, revolute leaf margins, flowers borne on pedicels 8–15 mm long, with petals up to 6 mm long and spreading or slightly recurved. Putterlickia verrucosa has leaves with distinct petioles, spinulose-denticulate mar- gins, much smaller flowers borne on pedicels up to 4 mm long, with petals up to 2 mm long and erect or slightly spreading. -

Birding Tour South Africa: Western Cape Custom Tour
BIRDING TOUR SOUTH AFRICA: WESTERN CAPE CUSTOM TOUR 8-12 OCTOBER 2016 By Chris Lotz Orange-breasted Sunbird (photo John Tinkler) www.birdingecotours.com [email protected] 2 | T R I P R E P O R T Western Cape custom tour October 2016 ITINERARY Date (2016) Location Overnight 8-Oct Cape Town to Tankwa Karoo Sothemba Lodge, Tankwa 9-Oct Full day in the Karoo Sothemba Lodge, Tankwa 10-Oct Tankwa Karoo to the Overberg Mudlark River Front Lodge 11-Oct Agulhas Plains Mudlark River Front Lodge 12-Oct Betty's Bay and Rooiels (back in Cape Town) Day 1: 8 October 2016 I fetched Robert and Elizabeth from Hotel Verde at Cape Town International Airport at 7:30 a.m., and we immediately started heading toward the amazingly endemic-rich Tankwa Karoo. But we had lots of birding to do before getting to the Karoo. En route we stopped in the famous Cape wine town of Paarl for an hour or two, as Paarl boasts some excellent birding sites and is perfectly right on the way to the Karoo. Just as we entered Paarl we were glad to be able to stop for a pale-phase Booted Eagle soaring above us – we actually ended up seeing a good number of this small eagle throughout our tour. After admiring the eagle we headed for the botanical garden within the Paarl Mountain Nature Reserve, where we got acquainted with a bunch of fynbos endemics and other goodies. This trip proved excellent for raptors. As we arrived at the botanical garden, we saw a Black Harrier hunting, then later we got amazingly close views of a perched African Goshawk – a two-accipiter morning is always a good morning! Three species of beautiful sunbirds were much in evidence: Malachite, Southern Double-collared, and Orange-breasted Sunbirds. -
The Behaviour of Reef-Dwelling Sparid Fishes
THE BEHAVIOUR OF REEF-DWELLING SPARID FISHES M. J. PENRITH1 CSIR Oceanographic Research Unit, University of Cape Town. ABSTRACT Notes on the behaviour of six species of sparid fish, all rock reef dwelling, and forming an important section of the inshore line fish industry in the southern Cape, are given. It is shown that these fIShes, although closely related, show very different feeding patterns. Notes on the breeding of Spondy/io soma emarginatum are given, and the male behaviour in nature is shown to differ from that observed in an aquarium. The line fish industry of the southern Cape coast is a primitive yet at times productive fishery. The fIShing is all done by hand line; traditionally cotton lines stiffened with ox blood were used, but heavy monoftlament lines have become universal in the last twenty years. The line ends with a round lead sinker and two traces, each with a single hook. An estimated catch of 20 000 short tons a year (not including snook, Thyrsites atun) is landed in the Republic and South West Africa (Division of Sea Fisheries Annual Reports) with this simple gear. In the area studied, Cape Point to the Tsitsikarna coast, the major catch comprises kabeljou (Johnius hololepidotus), geelbek (Atractoscion aequidens), yellowtail (Seriola lalanliii) and snook (l'hyrsites atun). These, however, are are all seasonal species, and between seasons a subsistence level fishery is undertaken with sparid fishes comprising the major portion of the catch. The sparid fIShes are important because they tide the crews over between seasons rather than as a profitable fishery, and it was for this reason that a study of their biology was undertaken as a joint project between the Division of Sea Fisheries and the Institute of Oceanography, University of Cape Town. -
Timeline Port Beaufort & Malgas
TIMELINE FOR PORT BEAUFORT & MALGAS 1488: The Portuguese recognized the Breede River Mouth as the finest natural anchorage on the whole southern seaboard of Africa. 1576: King Sebastian’s navigator, Manuel De Mesquita Perestrello called the bay, St. Sebastian’s Bay, after “Dom Sebastiao, the most serene King of Portugal”, and the west bank “Cape Infanta”. 1790: San Sebastian Bay was surveyed by the French sea captain, Captain Duminy. 1798: During May, the Breede River mouth was visited by Lady Anne Barnard and her husband, who was Colonial Secretary under the British Administration, with Jacob Van Reenen of Slang River. 1800: Landrost Anthonie Faure reported to Governor Sir George Young that the river was suitable for navigation “up to six hours inland, with excellent safe loading – places for small vessels along either bank”. 1802: Baron Von Buchenröder visited San Sebastian’s Bay, crossed the river in a small boat and pronounced it “only three to four feet deep at low tide, thus only suitable for sloops and long flat vessels, such as one sees on the Main, Nekker and Weser in Germany”. He also found an English ship anchored in the Breede River. 1803: Dirk Gysbert Van Reenen gave the same advice (as Baron Von Buchenröder) to General Janssens. 1813: Malagas got its name from the farm belonging to Adriaan Odendaal, “Malagas Craal gelegen aan de Breede River” which took its name from a former Khoikhoi Chief. 1817: It was found that the bar was navigable by vessels displacing not more than six feet of water. Lord Charles Somerset named the east bank of Breede River after the title of his father, the 5th Duke of Beaufort. -
Breede River Basin Study. Groundwater Assessment
DEPARTMENT OF WATER AFFAIRS AND FORESTRY BREEDE RIVER BASIN STUDY GROUNDWATER ASSESSMENT Final MAY 2003 Groundwater Consulting Services P O Box 2597 Rivonia 2128 Tel : +27 11 803 5726 Fax : +27 11 803 5745 e-mail : [email protected] This report is to be referred to in bibliographies as : Department of Water Affairs and Forestry, South Africa. 2003. Groundwater Assessment. Prepared by G Papini of Groundwater Consulting Services as part of the Breede River Basin Study. DWAF Report No. PH 00/00/2502. BREEDE RIVER BASIN STUDY GROUNDWATER ASSESSMENT EXECUTIVE SUMMARY The objectives of this study were to assess the significance and distribution of groundwater resources in the Breede River catchment, estimate the amount of abstraction and degree of stress it may be causing and to indicate the scope for further development of groundwater resources. This was achieved by a review of all available literature and obtaining yields and quantities from all significant schemes. The characterisation of important aquifers and assessment of the groundwater balance (recharge versus consumption) allowed for identification of further groundwater potential. The geohydrology of the Breede River catchment is controlled by the occurrence of the rocks of the Table Mountain Group (which form the mountainous areas), the occurrence of high levels of faulting and folding in the syntaxis area of the upper catchment and the variable rainfall, being highest in the mountainous areas in the west. These factors result in a catchment with highest groundwater potential in the west, where recharge, yields and abstraction potential are greatest and the quality is the best. As a result of these factors, the western half of the catchment is also the area with the greatest groundwater use. -
Banded Mongoose
Mungos mungo – Banded Mongoose Assessment Rationale The Banded Mongoose is listed as Least Concern as, although its distribution is restricted to the northeast of the assessment region, it is generally common in suitable habitat and is present in several protected areas. There are no major threats that could cause range-wide population decline. Accidental persecution through poisoning, controlled burning, and infectious disease may lead to local declines, whilst wildlife ranching might have a positive effect by conserving more suitable habitat and connecting subpopulations. Regional population effects: Dispersal across regional Chris & Mathilde Stuart borders is suspected as the range extends widely into Mozambique and is continuous into southeastern Regional Red List status (2016) Least Concern Botswana and southern Zimbabwe, and the species is not constrained by fences. National Red List status (2004) Least Concern Reasons for change No change Distribution Global Red List status (2016) Least Concern This species is distributed widely in sub-Saharan Africa TOPS listing (NEMBA) (2007) None from Senegal and Gambia to Ethiopia, Eritrea and Somalia, and south to about 31° in South Africa. It has CITES listing None been recorded to 1,600 m asl. in Ethiopia (Yalden et al. Endemic No 1996). Although fairly widespread in southern Africa, M. mungo appears to be rare in West Africa. Its relative In addition to living in groups numbering tens of scarcity in West Africa may be due to niche overlap with its individuals, Banded Mongooses are plural congener, the Gambian Mongoose (M. gambianus), breeders, females giving birth synchronously, and endemic to West Africa and reported to occupy similar provide cooperative care to the communal litter of habitat and have a similar diet (Cant & Gilchrist 2013; van pups (Cant & Gilchrist 2013). -

K. Lee Blue Hill Nature Reserve | University of Cape Town | University of KwaZulu-Natal Gillian McGregor Rhodes University Alastair Potts Nelson Mandela University Matthias Hammer (editor) Biosphere Expeditions 1 © Biosphere Expeditions, a not-for-profit conservation organisation registered in Australia, England, France, Germany, Ireland, U , the International Union for the Conservation of Nature and the European Citizen Science Association. Abstract The fynbos biome of South Africa is a biodiversity hotspot renowned for its very high plant species richness, endemic birds and the presence of the Cape mountain leopard, a small race of African leopard Panthera pardus ssp pardus. Biodiversity monitoring across a range of faunal and floral taxa was conducted in mountain fynbos habitat. Studies were conducted for two weeks in October 2017, with the help of international citizen scientists recruited by Biosphere Expeditions and based at Blue Hill Nature Reserve (Western Cape). In this report we provide a status update on the leopards of Blue Hill Nature Reserve for the period 2016-2020 through photo records. Camera-trapping confirmed the presence of male leopard ‘Strider’, resident since 2015 until early 2019. It also captured a female, suspected of being accompanied by a nearly fully-grown cub. -
Vegetation Map for the Riversdale Domain
VEGETATION MAP FOR THE RIVERSDALE DOMAIN Project Team: Jan Vlok, Regalis Environmental Services, P.O. Box 1512, Oudtshoorn, 6620. Riki de Villiers, CapeNature, Private Bag X5014, Stellenbosch, 7599. Date of report: March 2007 Suggested Reference to maps and report: Vlok, J.H.J. & de Villiers, M.E. 2007. Vegetation map for the Riversdale domain. Unpublished 1:50 000 maps and report supported by CAPE FSP task team and CapeNature. 2 Dedication: For Anne Lise, my dear wife, who motivated so strongly for this study to be done. I sincerely hope that this work will enable her, current and future CapeNature colleagues to contribute more towards the conservation and sustainable use of the biodiversity of the rather remarkable biodiversity of the Riversdale region. 3 EXECUTIVE SUMMARY The vegetation of a circa 800 000 ha area in the Riversdale region of the southern Cape was classified and mapped at a scale of 1:50 000 for the CAPE Fine-Scale Conservation Plan task team. The vegetation was mapped as their occurrence was perceived to be in the 17th century, thus before any transformation due to European impacts. The classification system follows a six-tier hierarchy in order to facilitate analyses at biome, habitat type and vegetation unit level. Aquatic and terrestrial systems are recognized, with two biomes within aquatic ecosystems and five biomes within the terrestrial ecosystems. Aquatic ecosystems cover approximately 12 percent of the domain and terrestrial ecosystems 88 percent. At habitat level, 47 habitat types are recognized; six are within the aquatic ecosystems and 41 in the terrestrial ecosystems. Brief descriptions and a photograph are provided for each habitat type.
