(University of Pretoria, 2009-09-17)The elephant debate deals largely with population size, how elephant numbers change over time, how they may affect vegetation, and how their populations should be managed. Trends in elephant numbers frequently motivate ...
-
(University of Pretoria, 2015)Savanna elephants currently inhabit some of the hottest environments in Africa. Because of climate change, these environments are likely to get hotter. Due to their large body size and small body surface area to volume ...
-
(University of Pretoria, 2018)Beta diversity, defined as the variation or turnover in species composition, is important to the understanding of how ecological communities assemble. Studies of beta diversity during secondary forest succession may thus ...
-
(University of Pretoria, 2014)Protected areas (PAs) cover 12.9% of Earth’s land, while just 5.8% has strict protection for biodiversity (Earth’s variety of ecosystems, species, and genetic variation). Constraints of size and configuration, mismanagement, ...
-
(University of Pretoria, 2007-06-13)Rehabilitation and revegetation of mined coastal sand dunes on the east coast of South Africa makes sense. It recovers ecosystem services such as carbon sequestration. The outcome of rehabilitation, which covers a third ...
-
(University of Pretoria, 1997)The present study is directed at obtaining information on the interaction between uterine steroid receptors and circulating steroids. Furthermore the study aimed at quantifying the affinity of these receptors for possible ...
-
(University of Pretoria, 2006-05-20)Human appropriation of natural resources, and the consequent loss of habitats, means that ecological restoration may in the future become a vital conservation tool. For this to happen, we have to understand the processes ...

(University of Pretoria, 2006-11-23)Please read the abstract in the 08summary part of this document
-
(University of Pretoria, 2005-11-22)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2015)Conservation management approaches for elephants in southern Africa, and particularly in the Kruger National Park, have changed. Recently, Kruger’s managers adapted their approach from artificially manipulating elephant ...
-
(University of Pretoria, 2007-08-18)The savanna elephant is a flagship species for conservation in Maputaland, a biologically diverse centre of endemism. At present Maputaland’s elephants are fragmented into two sub-populations, those confined to the Tembe ...
-
(University of Pretoria, 2008-08-12)Resources that can optimize survival are distributed unevenly across landscapes. I assumed that the distribution of these resources is reflected by landscape heterogeneity and that selection for areas with relatively high ...
-
(University of Pretoria, 2013)When elephants leave primary protected areas (PPAs), such as national parks and game reserves, they may come into conflict with people residing on the adjoining land. In this study, I attempted to determine why African ...
-
(University of Pretoria, 2007-04-07)A widely observed pattern in nature is a positive relationship between local abundance and spatial distribution. This study investigates this relationship amongst three taxa namely rodents, millipedes and trees on regenerating ...
-
(University of Pretoria, 2006-12-06)Please read the abstract before the references of this document.
-
(University of Pretoria, 2015)To improve the efficacy of protected areas in conserving ecological processes, initiatives such as the megaparks for metapopulations strive to increase connectivity between small and often isolated protected areas. Increasing ...
-
(University of Pretoria, 2008-04-18)Researchers use changes in bird community composition to illustrate ecological succession in restoration studies. These studies utilise a variety of methods, some of which may bias their outcomes. Here I used the point and ...
-
(University of Pretoria, 2011)Ecological restoration has the potential to stem the tide of habitat loss, fragmentation and transformation that are the main threats to global biological diversity and ecosystem services. Through this thesis, I aimed to ...
-
(University of Pretoria, 2010-08-13)Elephant management traditionally centers on reducing ecological impact and human-elephant conflict by controlling numbers. However, such an approach only deals with symptoms, and ignores the causes of the problem. Planning ...
