Scale, heterogeneity and secondary production in tropical rangelands
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Andrew Ash John Gross Mark Stafford SmithTropical rangelands across the world are experiencing land use intensification pressures which are reducing the spatial scale of grazing management units. There are implications of a reduction in scale on environmental heterogeneity and its relationship with secondary production of large... -
Lines around fragments: effects of fencing on large herbivores
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: RandallB Boone N Thompson HobbsPeople construct fences to delineate land ownership and to control access to land. Fences accomplish several purposes, notable among these are containing livestock or wildlife raised for profit or subsistence, excluding use of vegetation within areas to be conserved and... -
Early survival and growth of vegetatively propagated indigenous grasses in a clear-felled timber plantation in KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: JCO du Toit --- School of Biological and Conservation Sciences, South AfricaTransformation of natural landscapes can result in the local extinction of many plant species. If the new land use is discontinued, many original species will not recolonise the area, necessitating their reintroduction for rehabilitation purposes. One method is to fragment... -
Fragmented participation in management of the fishery for small pelagic fish in South Africa – inclusion of small-rights holders is a complex matter
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MM Hara --- Institute for Poverty, Land and Agrarian Studies [PLAAS], University of the Western Cape, South Africa J Rogerson --- Institute for Poverty, Land and Agrarian Studies [PLAAS], University of the Western Cape, South Africa J de Goede --- Pelagic and High Seas Fisheries Management, Branch: Fisheries Management, Department of Agriculture, Forestry and Fisheries [DAFF], South Africa J Raakjær --- Innovative Fisheries Management [IFM], Department of Development and Planning, DenmarkThe reasons why most small-rights holders do not participate in management of the fishery for small pelagic fish (‘small pelagics’) in South Africa, despite legislation and policy encouraging their participation, were analysed. Membership of the Small Pelagics Management Working Group... -
Factors affecting diet, habitat selection and breeding success of the African Crowned Eagle Stephanoaetus coronatus in a fragmented landscape
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Christopher J Swatridge --- School of Biosciences, UK Ara Monadjem --- All Out Africa Research Unit, Department of Biological Sciences, Swaziland David J Steyn --- , South Africa Garth R Batchelor --- , South Africa Ian CW Hardy --- School of Biosciences, UKThis study aimed to identify variables that affect habitat selection and nesting success of the African Crowned Eagle Stephanoaetus coronatus, the largest forest raptor, in north-eastern South Africa. A preference for nesting in the Northern Mistbelt Forest vegetation type was... -
Fragmented populations of leopards in West-Central Africa: facing an uncertain future
Item type: Journal Article • Journal: African Zoology • Authors: Pauline Toni --- Université de Rennes 1, France Thierry Lodé --- Université de Rennes 1, FranceDuring recent decades, most endangered species have suffered serious population declines. Little has been documented on leopards inWest-Central Africa and as a result the efficiency of protection measures and wildlife managing practices can be questioned. Using 416 occurrences of leopards,... -
Current distribution of the southern barred minnow, Opsaridium peringueyi (Pisces: Cyprinidae), in South Africa:Is there reason for concern?
Item type: Journal Article • Journal: African Zoology • Authors: J.A. Venter --- School of Biological and Conservation Sciences, South Africa P.S.O. Fouché --- Zoology Department, South Africa W. Vlok --- Centre for Aquatic Research, Department of Zoology, South AfricaIn South Africa, relatively small, but healthy populations of Opsaridium peringueyi remain in the middle reaches of the Luvuvhu, Blyde, Sabie and Pongolo Rivers. The species may be extinct in some rivers like the Shingwedzi and lower-Olifants and its status... -
Spatial metrics effect of forest fragmentation on forest bird abundance and site occupancy probability: the influence of patch size and isolation
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Robert B Modest --- Department of Wildlife Management, Tanzania Shombe N Hassan --- Department of Wildlife Management, Tanzania Alfan A Rija --- Department of Wildlife Management, TanzaniaThe persistence of species taxa within fragmented habitats is dependent on the source–sink metapopulation processes, and forest patch size and isolation are key factors. Unveiling species–patch area and/or species–patch isolation relationships may help provide crucial information for species and landscape... -
Seasonal use of remnant forest fragments by understorey forest birds in the Uluguru Mountains, Tanzania: a conservation priority
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Chacha Werema --- Department of Zoology and Wildlife Conservation, Tanzania Kim M Howell --- Department of Zoology and Wildlife Conservation, Tanzania Henry J Ndangalasi --- Department of Botany, TanzaniaForest fragmentation can lead to extinctions of some species at local levels and is eroding bird diversity at an increasing rate. While there is information on the distribution of forest bird species in most of the Eastern Arc Mountain forests,... -
Did informed order flow move to multilateral trading facilities? Evidence for some Eurozone countries
Item type: Journal Article • Journal: Investment Analysts Journal • Authors: Paulo Pereira da Silva --- CEFAGE, Universidade de Évora, PortugalThis paper investigates the effects of the fragmentation of European stock markets after MiFID application in 2007. Specifically, we discuss whether the process of fragmentation elicited a flight of informed trading from the primary stock exchanges to the incoming multilateral... -
Remote sensing of forest health and vitality: a South African perspective
