[Truncated abstract] Understanding the effect that the disturbance of habitat by humans has on the population dynamics and ecology of wild animals is critical for the management of these populations. By understanding the demographic effects of disturbance the ways in which a population can be managed to increase or decrease its rate of change in size also become apparent. This thesis describes the effect that human disturbance, through the establishment of a large naval base, has had on the population dynamics and ecology of tammar wallabies (Macropus eugenii) on Garden Island, Western Australia. The disturbance of the environment on the HMAS Stirling Naval Base included the establishment of large areas of irrigated and fertilised couch grass (Cynodon dactylon) that increased and made virtually constant the amount of food available to the tammars in that area. In addition, traffic associated with the naval base resulted in large numbers of tammar wallabies being killed by vehicles. The effects of these disturbances were determined by comparing population dynamics, through vital rates of survival and fecundity and population growth rates, and spatial ecology, through the size of the animals' home ranges, in three areas of Garden Island. The three areas were the naval base (highly disturbed), southern bushland (adjacent to the naval base) and the northern bushland (undisturbed). The tammars on the naval base were in better body condition than those living in the two bushland areas of the island. ... When the impact of road-kills was removed, increased to 1.150.101 per year on the naval base and 0.960.076 per year in the southern bushland. Fecundity transitions, defined as the product of the rates of birth and pouch-young survival, and adult survival rates were lower in the bushland areas compared with the naval base in two of the three years, which were the main reasons for the lower estimates. There were no significant differences in the size of the tammars' home ranges between areas with modified or unmodified habitats or between the sexes (P>0.05). In summer the mean size of the home ranges was 3.90.66 ha, which was larger than winter when home ranges were 3.20.54 ha, but this difference failed to reach significance (P=0.058). These results indicate that the modification of the tammars' habitat has probably not caused significant changes in the size of the animals' home ranges. The size of the home ranges of tammar wallabies is likely to be determined by a complex interaction of many factors, and habitat modification alone has not been sufficient to cause substantial changes. The results presented in this thesis demonstrate that the disturbance caused by the establishment of the naval base on Garden Island has altered the population dynamics of the tammars wallabies, through increasing in the amount of food available to the tammars and through high numbers of road-kills. These results also demonstrate how gaining detailed knowledge of population dynamics can have direct application to managing the impact of disturbance on populations of wild animals.

While it is now well established that many Europeans were delighted with the landscapes they encountered in colonial Australia, the pioneer narrative that portrays colonists as threatened and alienated by a harsh environment and constantly engaged in battles with the land is still powerful in both scholarly and popular writing. This thesis challenges this dominant narrative and demonstrates that in a remarkably short period of time some colonists developed strong connections with, and even affection for, their 'new' place in Western Australia. Using archival materials for twenty-one colonists who settled in five regions across southern Western Australia from the 1830s to the early 1900s, here this complex process of belonging is unravelled and several key questions are posed: what lenses did the colonists utilise to view the land? How did they use and manage the land? How were issues of class, domesticity and gender roles negotiated in their 'new' environment? What connections did they make with the land? And ultimately, to what extent did they feel a sense of belonging in the Colony? I argue that although utilitarian approaches to the land are evident, this was not the only way colonists viewed the land; for example, they often used the picturesque to express delight and charm. Gender roles and ideas of class were modified as men, as well as women, worked in the home and planted flower gardens, and both men and women carried out tasks that in their households in England and Ireland, would have been done by servants. Thus, the demarcation of activities that were traditionally for men, women and servants became less distinct and amplified their connection to place. Boundaries between the colonists' domestic space and the wider environments also became more permeable as women ventured beyond their houses and gardens to explore and journey through the landscapes. The selected colonists had romantic ideas of nature and wilderness, that in the British middle and upper-middle class were associated with being removed from the land, but in colonial Western Australia many of them were intimately engaged with it. Through their interactions with the land and connections they made with their social networks, most of these colonists developed an attachment for their 'new' place and called it home; they belonged there.

Thesis (MScFor)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: Free-ranging lions (Panthera leo) in the Kgalagadi Transfrontier Park (KTP) have been subject to persecution by farmers following livestock depredation in adjacent grazing areas. In recent years at least one adult female was killed annually from a sub-population of five boundary prides that have home ranges adjoining these livestock grazing areas. While no long-term records of human-caused mortality are available, the impact of current rates of human-caused mortality is uncertain. Female-based, age-structured models were thus used to estimate the long-term viability of the KTP lion sub-population subjected to human-caused mortality under deterministic and stochastic environmental conditions. Population parameters incorporated in the models included age-class specific natural mortality, female fecundity and birth sex ratio. In so doing sustainable threshold rates of persecution were established, so that effective conservation measures can be taken, if required, to ensure the continued survival of boundary prides in the park. Sensitivity analyses of natural survival rates indicated that adult female survivorship is the most important population parameter with respect to maintaining population viability, compared to younger female age-classes, fecundity or birth sex ratio. Hence adults were also the most sensitive age-class with respect to human-caused mortality, as adult survival repeatedly acts upon individuals with the highest reproductive value. In the deterministic model, with the most optimistic survival parameter values, fecundity and birth sex ratio (female-biased) estimates, the sub-population is only able to sustain an annual persecution of three adult females, before the sub-population exhibits a sustained decline. In the worst-case scenario, where fecundity and sex ratio estimates are at their lower extremes, the maximum sustainable age-class specific persecution rate is zero, for all age-classes. Whilst these hypothetical scenarios are unrealistic, they do highlight the extreme thresholds of potentially sustainable persecution rates. Under the most optimistic scenario using the stochastic model, the highest achievable survival probability of the sub-population, when subjected to a persecution rate of one adult annually, was 78%. Although increased fecundity and birth sex ratio biased towards females may increase the survival probability, these parameters are generally at their mean values in the long-term, and may thus not necessarily prevent a sustained population decline. The models therefore suggest that the current persecution rate of one adult annually (or 4% of the adult sub-population), appears unsustainable in the longterm. To ensure the survival of existing boundary prides and to maintain a viable subpopulation, adult lionesses should, as far as possible, be afforded protection from persecution. / AFRIKAANSE OPSOMMING: Vrylewende leeus (Panthera leo) in die Kgalagadi Oorgrenspark (KTP) is onderworpe aan vervolging deur boere as gevolg van predasie op vee in aangrensende weidingsgebiede. In onlangse jare is ten minste een volwasse wyfie uit ‘n subpopulasie van vyf troppe met loopareas wat aan die weidingsgebiede grens, jaarliks uitgewis. Geen langtermyn rekords van vrektes as gevolg van menslike oorsake is beskikbaar nie, en die impak van vrektes wat deur mense veroorsaak word, is dus onseker. Wyfie-gebaseerde, ouderdomgestruktureerde modelle is daarom gebruik om te voorspel wat die langtermyn lewensvatbaarheid is van die KTP leeu subpopulasie wat onderworpe is aan vrektes deur menslike invloede onder deterministiese en stogastiese omgewingsfaktore. Bevolkingsfaktore wat deur die modelle in ag geneem is, sluit ouderdomsgroep-spesifieke natuurlike vrektes, aanwas van wyfies en geboorte geslagsverhouding in. Sodoende is volhoubare uitwissingstempos bepaal sodat, indien nodig, effektiewe bewaringsmeganismes toegepas kan word om die voortbestaan van troppe in die grensgebiede van die park te verseker. Sensitiwiteitsanalises van natuurlike oorlewingstempos het aangetoon dat volwasse wyfies se oorlewing die belangrikste bevolkingsfaktor is om die bevolking se lewensvatbaarheid te volhou vergeleke met jonger wyfie ouderdomsgroepe, aanwas of geslagsverhouding by geboorte. Daarom was volwassenes ook die sensitiefste vir vrektes as gevolg van menslike invloede, omdat die oorlewing van volwassenes herhaaldelik inwerk op individue met die hoogste reproduktiewe waarde. In die deterministiese model met die mees optimistiese oorlewing, aanwas en geboorte verhouding (wyfie-gebasseerde) beramings, is die subpopulasie slegs in staat om ‘n jaarlikse uitwissing van drie volwasse wyfies te onderhou, voordat die sub-populasie ‘n volgehoue afname toon. In die uiterste geval waar aanwas en geslags verhouding skattings op die laagste is, is die maksimum volhoubare ouderdomsklasspesifieke beramings nul vir alle ouderdomsklasse. Terwyl hierdie hipotetiese senario’s onrealisties is, onderstreep dit die uiterste vlakke van potensiële volhoubare uitwissingstempos. Onder die mees optimistiese senario – ‘n uitwissingstempo van een volwassene jaarliks – met die gebruik van die stogastiese model, was die hoogste haalbare oorlewingswaarskynlikheid van die sub-populasie 78%. Alhoewel ‘n toename in aanwas en geboorte geslagsverhouding (met oorhelling na wyfies), ‘n toename in oorlewingswaarskynlikheid tot gevolg kan hê, is hierdie faktore oor die algemeen gemiddeld oor die langtermyn en sal dit nie noodwendig ‘n volgehoue afname in die populasie verhoed nie. Die modelle dui daarop dat die huidige uitwissingstempo van een volwassene (of 4% van die volwasse sub-populasie) op ‘n jaarlikse grondslag onvolhoubaar is oor die langtermyn. Om die oorlewing van bestaande troppe in die grensgebiede, asook ‘n lewensvatbare subpopulasie, te verseker, moet volwasse leeuwyfies so ver as moontlik teen vervolging beskerm word.

Thesis (MA (Geography and Environmental Studies)--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This research focuses on the black rhinoceros and ecotourism in three conservation areas in the Kunene region of Namibia. The reciprocal impact between black rhino and community-based ecotourism is analysed. The research is located in two communal conservancies, #Khoadi-//Hôas and Torra, and in a photographic tourism concession, the Palmwag Concession Area. The research aims to explore and describe the reciprocal impact of community-based ecotourism efforts and black rhino spatial movement patterns in three conservation areas in north-west Namibia. An in-depth literature review was undertaken on the reciprocal impact between rhino-tracking tourism and conservation. A comparison was also made between the effects of human-induced disturbance on spatial movement patterns of black rhinos and the perception of tourists about tracking black rhinos. The value of black rhinos to community-based ecotourism was also determined. Quantitative research methodology was used for this study. Explorations of objectives were conducted through direct field observation with the aid of radio-telemetry tracking and aerial surveying for data gathering. The researcher employed SRT (Save the Rhino Trust) trackers in the study areas to assist with the tracking. The sample consisted of 24 transmitter-fitted black rhino in the three conservation areas. Rhino not fitted with transmitters have been included in the sample for more accurate results. Four hundred questionnaires were distributed at four tourist lodges in the study area. The hypothesis that sustainable ecotourism does not influence black rhino spatial behaviour was rejected. Rhinos in the study were easily disturbed and did not readily return to undisturbed behaviour. Their major response to disturbance was to run away. The disturbance was influenced by their initial activity when found. The highest disturbance occurred early in observations. Rhinos illustrated similar causes of disturbance throughout the study sites. The Springbok River emerged as the area with the most severe reactions to disturbance. This was supported by home range data and ecological constraints. Analysis of tourist responses regarding rhino tracking indicated a high demand for and level of satisfaction. This was the single determining factor for tourists to return to the Kunene region to do rhino tracking again. Tourists were willing to pay close to market price to track black rhino. It is recommended that tracking of black rhino should be avoided in the Springbok River and Aub/Barab areas. Tracking protocols should stipulate that tracking should only be conducted early in the morning; that rhinos may only be approached from downwind; that observation time may not exceed 15 minutes; that groups must be kept small; and that the approach distance may not be less than 100 metres. / AFRIKAANSE OPSOMMING: Die fokus van die navorsing is op swart renosters en ekotoerisme in drie bewaringsgebiede in die Kunene streek van Namibia. Die wedersydse wisselwerking tussen swart renosters en gemeenskaps-gebaseerde ekotoerisme is nagevors. Die navorsing het plaasgevind in twee kommunale bewaringsgebiede, #Khoadi-//Hôas en Torra asook ‘n konsessie vir fotografie in die Palmwag Konsessie Gebied. Die doel van die navorsing was om die wedersydse wisselwerking van gemeenskapsgebaseerde ekotoerisme en swart renosters se geografiese bewegingspatrone in drie bewaringsareas in noordwes Namibië te ondersoek en te omskryf. ‘n Deeglike literatuurstudie is gedoen ten opsigte van die wedersydse wisselwerking tussen toerisme met die doel om renosters waar te neem deur spoorsny en bewaring van die spesies. Die uitwerking van versteuring deur mense op die geografiese bewegingspatrone van swart renosters is vergelyk met die persepsie van toeriste ten opsigte van spoorsny van swart renosters. Die waarde van swart renosters ten opsigte van ekotoerisme is ook bepaal. Kwantitatiewe navorsingsmetodologie is gebruik in die studie. Die doelstelling van die navorsing is uitgevoer deur direkte veld waarnemings met behulp van radio-telemetriese opsporing en data insameling met behulp van lugsensusse. Die navorser het spoorsnyers van SRT (Save the Rhino Trust), wat in die studiegebied werk, in diens geneem om van hulp te wees met die spoorsny van renosters. Die steekproef het bestaan uit 24 swart renosters toegerus met seintoestelle in drie bewaringsgebiede. Renosters wat nie seintoestelle gehad het nie, is ook in die steekproef ingesluit ten einde beter dekking te verkry. Vierhonderd vraelyste is by vier toeristeoorde in die studiegebied versprei. Die hipotese dat volhoubare ekotoerisme nie ‘n invloed uitoefen op die geografiese gedrag van swart renosters nie, is verwerp. Renosters in die studie-gebied is maklik versteur en het nie geredelik teruggekeer tot onversteurde gedrag nie. Hulle reaksie op versteuring was gekenmerk deur weg te hardloop. Die mate van versteuring is bepaal deur die renosters se aanvanklike aktiwiteit by opsporing. Die meeste versteuring het gedurende vroeë waarneming plaasgevind. Dieselfde oorsake van versteuring is in al drie gebiede gevind. Die Springbokrivier was die gebied waar die sterkste reaksies ten opsigte van versteuring bespeur is. Dit word ondersteun deur die grootte van die loopgebiede van die renosters en ekologiese beperkings van die gebied. Data-analise van toeriste-vraelyste het aangetoon dat daar ‘n groot aanvraag en belangstelling is in die spoorsny van renosters. Die grootste bepalende faktor vir toeriste om na die Kunene streek terug te keer, is om renosters te sien deur middel van spoorsny. Toeriste is gewillig om die heersende markprys vir spoorsny van renosters te betaal. Navorsingsaanbevelings sluit in dat spoorsny van swart renosters in die Springbokrivier en Aub/Barab gebiede vermy word. Spoorsny-protokol moet stipuleer dat dit net in die vroeë oggend gedoen word, dat renosters slegs van onderkant die wind genader word, waarnemingstyd mag nie 15 minute oorskry nie, groepe moet klein wees en die afstand vanaf die diere mag nie nader as 100 meter wees nie.

The aim of the project was to explore the acquisition and dissemination of knowledge amongst decision-makers involved in the management of red deer in Scotland. While research exists on the ecology of red deer habitat, no research exists that focuses on the relationship between the deer and the people responsible for their management. Therefore, this thesis is primarily qualitative research which aimed to explore the various aspects of red deer management in Scotland within the socio-ecological context in which it exists. There are numerous groups with interest in red deer management, however this research, due to scope and time restrictions, was limited to two primary groups, the individuals tasked with implementing policy and the practitioners who carry out culling. During the course of the project, under-researched topics surfaced, highlighting areas of practical and theoretical divergence between stakeholders. This thesis therefore aims to explore how differing views and perspectives of two of the key stakeholder groups – the estate-based practitioners (including stalkers, land-managers, and land-owners) and staff of governmental agencies – influence the management of red deer in Scotland. This research indicates that people with different roles hold different relationships with the deer, which affect management decisions and implementation at local, regional, and/or national level. As with other areas within conservation and wildlife management, this research indicates there is a disconnect between blanket governmental policy and site-specific needs, with a lack of inclusion of practitioner knowledge. Potential future research would include additional qualitative research to follow up some of the management issues raised by this research and formulate recommendations for changes to practice, followed by collection of quantitative data assessing the efficacy of interventions.

In this dissertation we explore the concept that the works of God continue in a creative and coherent continuum from the portrayal in Genesis 1 to the description of their consummation in Revelation through the dynamic broad movement of the Kingdom of God that moved through Israel and the other nations of the world and through the churches and other institutions as well as in the Bible, in the experiences of humanity and in the vast non-human creation. Therefore creation, redemption, renewal and consummation are seen to be linked in a process which is not confined to the usual theological pointers of the Church and the Bible. Churches and the Bible are signs and instruments of the Kingdom of God amongst and in the many universes and not the only signs and instruments of the Kingdom of God in and amongst the many universes. The importance of the coherence between each work of God, the otherness of each work and the ongoing character of God's works demonstrates itself in the impact of faith on human experience and on the very existence of human beings. The concept of developing a wholesome person with a fivesome awareness is developed, this being an awareness of a human beings creatureliness, an awareness of their sinful tendencies of doing damage to God, the self as being created by God and all other creatures of God, an awareness of the salvific and reconciliatory power of the cross and resurrection of Jesus Christ and an awareness of the renovating and renewal power of the Spirit of Pentecost which is carrying and guiding the process of the fivesome awareness in our minds, our experiences and our living into afterlife towards the consummation of all things in the new heaven and the new earth. The ongoing experience of anticipatory fragments and moments of meaning and significance breaking in from the future into our current life, bridges God's Kingdom works in the future through reflective understanding of faith experience with our everyday experience as human beings. The basic point and the thrust of this dissertation is that of a `both...and' and not an `either...or' relationship between human beings and their experience of God as Creator, their own falling into sin, God as Reconciliator in Christ, God the Holy Spirit as the Renewer and Renovator of all things unto afterlife and the creation of the new heaven and the new earth - the whole ongoing process of God's works is attested in the Biblical texts and attested in the foursome and inclusive experiential awareness of God's works in our daily experience by the Holy Spirit. / Systematic Theology and Theological Ethics / M.Th.

The research on "The healing touch of Nature in the context of pastoral therapy" illustrated the role of Nature in bringing healing to individual people in an urban context in South Africa. The role Nature plays in connecting the participants with God and how this positively affects their daily lives, has been central in the research. Through their interaction with Nature, the participants lead richer, more meaningful lives and experience a greater sense of well-being. Nature stimulates and elicits response as the digital world is set against the calm energy and "warmth of the earth". Through connection with God in Nature, the participants translate the healing metaphor into more tangible "language" – the "beautifying effect" of Nature. It is not the words that captivate, but the thoughts which the words carry. Mostly the research tells the story of the experiential knowledge of living in the intimate presence of God and the healing power of God‘s presence. This narrative is about a kind of knowing that can only come through Nature. The research offers a way of seeing Nature that could influence pastoral care today. / Philosophy, Practical and Systematic Theology / M. Th.

Surface water pollution is prevalent in numerous areas of central Roodepoort mainly due to gold mining activities. The surface water quality for the Bosmontspruit, Russell’s Stream and the New Canada Dam was assessed from October 2010 to March 2011. Physical, chemical and biological characteristics of the water were determined for 8 monitoring points and the results obtained were compared with the In-stream water quality guidelines for the Klip River catchment and the South African Water Quality Guidelines. A trend noticed throughout the sampling period was the non-compliance in the levels of total dissolved solids (TDS) and dissolved oxygen. The results indicated that concentrations of iron, aluminium, nickel, manganese and potassium were above the limit across the Bosmontspruit and Russell’s stream. There was also significant evidence of excessive faecal coliform and ammonium pollution in the Bosmontspruit. During the monitoring period it was noted that water from these streams were utilised for crop irrigation, bathing, livestock and human consumption and may pose a health hazard due to poor water quality. / Environmental Sciences / M.Sc.

Text in Afrikaans / Teen die agtergrond van toenemende gewelddadige gedrag binne die konteks van verskillende bevolkingsgroepe en gemeenskappe, is reeds ·heelwat navorsing ten opsigte van die aard en oorsake van aggressiewe gedrag onderneem. Aggressiwiteit as vorm van afwykende gedrag is nog nooit deur die onderskeie gemeenskappe in die Republiek van Suid-Afrika aanvaar nie. Die oorsake van aggressiwiteit word deur verskillende navorsers vanuit wydverspreide ooghoeke benader. Hoewel fisiologiese oorsake van aggressiewe gedrag nie deur die skrywer ontken word nie, word in hierdie studie die volwasse mens as verantwoordelike en verantwoordbare wese se motivering vir aggressiewe gedrag van naderby beskou. 'n Weldeurdagte literatuurstudie oor aggressiwiteit sowel as die basiese hunkeringe van die mens in die kontemporer-moderne wereld, het aan die lig gebring dat mense verskillend optree al sou hulle aan dieselfde samelewingseise blootgestel word. Ervaringsreste, veral ten opsigte van pedagogiese verhoudings, blyk 'n groat rol in die vorming van die selfbeeld sowel as belewing en hantering van krisissituasies te speel. Die mens staan nooit alleen in die wereld nie, maar is voortdurend in 'n verhouding betrokke. Die noodwendigheid van verhoudings raak horn as sosiale wese, en is ten nouste gekoppel aan belewing en beagting van die self. Defhalwe word die ervaring van verhoudings uit veral die kinderdae, of te wel pedagogiese verhoudings, as van deurslaggewende belang by die vorming van die selfbeeld beskou. Die bevindinge van hierdie studie is geverifieer by wyse van 'n idiografiese ondersoek. Gevangenes wat aggressiewe misdade gepleeg het, is op vrywillige basis by die navorsing betrek. Na aanleiding van genoemde bevindings is dit nodig geag om 'n gestandaardiseerde vraelys vir die meting van elkeen se selfbeeldstand in te skakel. Aanbevelings is geformuleer nadat insig uit navorsingsresultate ten aansien van die interafhanklikheid van pedagogiese verhoudings, selfbeeldvorming en aggressiwiteit, verkry is. Hierdie aanbevelings is veral gerig op steungewende, terapeutiese begeleiding van die aggressiewe oortreder sodat hy vaardighede kan aanleer waar~olgens hy lewenskrisisse kan begryp en hanteer. / Extensive research has already been undertaken in respect of the nature of aggression against the background of increasingly violent behaviour within different population groups and communities. Aggression as a form of deviant behaviour has never been accepted by the various communities in the Republic of South Africa. Researchers have investigated the causes of aggression from a wide range of perspectives. Although the author does not deny the existence of physiological causes of aggressive behaviour, this research focuses on the motivation for aggressive behaviour in the adult as responsible and accountable being. A thorough study of the literature concerning aggression as well as, the basic yearnings of man in the contemporary modern world, revealed a diversity in human behaviour even when people were confronted with the identical demands of society. Past experience, especially in connection with pedagogic relations, appears to have an important impact on not only the formation of the self-image but also how people experience and cope with crisis situations. Man is never in the world in isolation but is continuously involved in relationships. This essentiality of relationships affects him as a social being and is intimately a,ssociated with the experiencing and evaluation of the self. Experiences with relationships, especially in childhood, that is pedagogic relationships, are therefore, of cardinal importance in self-image formation. The findings of this research were verified by means of ideographic studies. Prisoners who had perpetrated violent crimes were included in this research on a voluntary basis. In accordance with the findings it was considered necessary to incorporate a standardized questionnaire to measure the state of the self-image of each prisoner. Recommendations were formulated after obtaining insight arising from research findings which focussed on the interdependence of pedagogic relationships, self-image formation and aggression. These recommendations are mainly directed at the supportive therapeutic guidance of the aggressive transgressor in order that he may acquire skills to understand and cope with the crises of life. / Educational Studies / D.
