Fire and life history affect the distribution of plant species in a biodiversity hotspot
(Wiley, 2019)Aim: Species distribution models (SDMs) provide valuable insights into species–environment relationships and potential climate change impacts on diversity. Most SDMs do not account for the role of natural disturbance ... -
Fire‑mediated disruptive selection can explain the reseeder–resprouter dichotomy in Mediterranean‑type vegetation
(Springer, 2014)Crown fire is a key selective pressure in Mediterranean-type plant communities. Adaptive responses to fire regimes involve trade-offs between investment for persistence (fire survival and resprouting) and reproduction (fire ... -
Food for body and soul : tourism development opportunities in the Western Cape
(SUN MeDIA, 2013)This article applies spatial multiple criteria evaluation (MCE) by weighted linear combination of factor layers in a computerised geographical information system (GIS) to aid development of spatial policy and planning of ... -
Framing the concept of satellite remote sensing essential biodiversity variables : challenges and future directions
(John Wiley & Sons Ltd., 2016-03)Although satellite-based variables have for long been expected to be key components to a unified and global biodiversity monitoring strategy, a definitive and agreed list of these variables still remains elusive. The growth ... -
Free satellite data key to conservation
(American Association for the Advancement of Science, 2018-07)INTRODUCTION: Biodiversity is in crisis, with extinction rates orders of magnitude higher than background levels (1). Underfunded conservationists need to target their limited resources effectively. Over the past ... -
Future land cover change scenarios in South African grasslands - implications of altered biophysical drivers on land management
(Elsevier, 2018)Future land cover changes may result in adjustments to biophysical drivers impacting on net ecosystem carbon exchange (NEE), catchment water use through evapotranspiration (ET), and the surface energy balance through a ... -
Game, fences and motor vehicle accidents : spatial patterns in the Eastern Cape
(South African Wildlife Management Association, 2005-10)In South Africa, very little research on motor vehicle accidents involving animals has been done. Transport networks expand while traffic volumes and speed increases. Animals entering the road reserve pose dangers to ... -
Gaps in the protected area network for threatened Afrotropical birds
(Elsevier, 2004)Protected areas established for wildlife conservation (IUCN category I–VI protected areas) or for forest and watershed conservation (forest reserves) across mainland sub-Saharan Africa have high biodiversity values. However, ... -
Gated developments : international experiences and the South African context
(SUN MeDIA Bloemfontein, 2012)Gated developments, more commonly known as gated communities, have become a feature of urban living throughout the world. Gated developments in South African cities are an ubiquitous feature of the contemporary urban ... -
Geo-information pyramids for up-to-date and flexible conservation plans : a case study for Transfrontier Conservation Areas
(OpenJournals Publishing, 2007)The initiative to link habitat and parks across political borders, to form large Transfrontier Conservation Areas (TFCAs), has gained momentum in Africa and the world. TFCAs hold many advantages, one of them being the ... -
The geographical distribution of diagnostic medical and dental X-ray services in South Africa
(Health & Medical Publishing Group, 1998)Aim. The aim of this study was threefold, viz.: (/) to evaluate the availability and accessiblity of medical and dental X-ray services in South Africa; (//) to evaluate geographical information systems (GIS) as a tool for ... -
A geographical profile of the South African population as a basis for epidemiological cancer research
(Health & Medical Publishing Group, 1988)Because people do not necessarily become ill proportionally, particular subgroups of the population are more susceptible to certain types of disease than others. It is also essential to take spatial distribution and ... -
Die groot avontuur – wondere van lewe op aarde
(AOSIS OpenJournal, 2007)Leon Rousseau se Die groot avontuur is ’n populêre wetenskap oor die geskiedenis van lewe op aarde. Populêr-wetenskaplike tekste stel hoë eise aan die skrywer: aktualiteit, toeganklikheid van aanbieding, ’n getroue ... -
Growth potential study 2014
(Western Cape Government, 2014-03)This study determined the growth potential and socio-economic needs of settlements in the Western Cape outside of the Cape Town metropolitan area using quantitative data (e.g. factors relating to socio-economic, economic, ... -
A hierarchical Bayesian model of wildfire in a Mediterranean biodiversity hotspot : implications of weather variability and global circulation
(Elsevier, 2010)In this study we combined an extensive database of observed wildfires with high-resolution meteorological data to build a novel spatially and temporally varying survival model to analyze fire regimes in the Mediterranean ... -
I fish because I am a fisher : exploring livelihood and fishing practices to justify claims for access to small-scale fisheries resources in South Africa
(AOSIS, 2021)In South Africa, claims for and access to natural resources are deeply embedded in people’s histories, identities and livelihood experiences. As in the case of land, access to and rights over fisheries resources is a highly ... -
Identifying the challenges of creating an optimal dissemination geography for census
(CONSAS Conference, 2015-02)The importance of census data in government and private-sector planning cannot be underestimated. However, the geographic level at which it is made available for different users, is a highly debateable issue. ... -
Impact of ecological redundancy on the performance of machine learning classifiers in vegetation mapping
(Wiley Open Access, 2017)Vegetation maps are models of the real vegetation patterns and are considered important tools in conservation and management planning. Maps created through traditional methods can be expensive and time-consuming, thus, ... -
Input variable selection for interpolating high-resolution climate surfaces for the Western Cape
(Water SA, 2011-07)Accurate climate surfaces are vital for applications relating to groundwater recharge modelling, evapotranspiration estimation, sediment yield, stream flow prediction and flood risk mapping. Interpolated climate surface ... -
Into the future : Donkergat military training area and the Langebaan Ramsar site
(AOSIS, 2019-02-26)Militaries need natural areas for offensive and defensive combat-readiness programmes. Here soldiers, war machinery and munitions are employed to prepare forces to execute warfighting tactics. Integration of environmental ...
