Abstract:

This thesis examines water conservation in the upper valley of the Huai River in Anhui Province, close to the border between north and south China, during the Republic of China (ROC) era (1912-1949). Two main flood relief and water conservation projects are studied in detail. In order to gain a deeper and broader understanding of water conservation policies and practices in China during that period, additional comparative studies were undertaken of two water conservation projects in the lower areas of the Yangtze River in south and northwest China. The main question addressed in the thesis is:

Abstract:

Landscapes are changing environments. Conservation of the amenities associated with landscapes must take into account the tendency of a landscape to change over time. Change is considered to be influenced by both cultural land use practices and natural resource processes which act on the landscape. A technique is developed which demonstrates an approach to measure the stability of landscapes. This approach also provides a means to qualify the importance of the elements which make up the landscape, thus defining the matrix of the landscape.

Abstract:

There is little doubt that anthropogenic climate change will have long lasting, unavoidable, large scale and cross sector effects. Having a clear understanding of the scale and rate of projected future changes, and the potential impacts of those changes at multiple spatial and temporal scales, will be important to allow environmental managers the best chance of adapting to changing conditions. There are particular concerns about impacts on freshwater systems due to the coupling of direct impacts to both hydrology and ecology. Expected changes can be grouped into three functional categories: th

Wireless sensor networks suffer from limited power resources. Therefore, managing the energy constraints and exploring new ways to minimize the power consumption during the operation of the nodes are critical issues. Conventional MAC protocols deal with this problem without considering the internal properties of the sensor nodes’ batteries. However, recent studies about battery modeling and behaviour showed that the pulsed discharge mechanism and the charge recovery effect may have a significant impact on wireless communication in terms of power saving.

The aim of this thesis is to examine the nature of the changes that took place within paper conservation, a section of the practice/occupation of material conservation, in the United Kingdom during the period from 1975 to 2005. In the 1970s, conservation emerged as a distinct practice within the museum sector from two sources: semi-skilled cleaners and movers of art objects, and the traditional restorers of cultural objects. From then until the end of the century, it continued to grow and mature. The nature of this growth and the changes that took place within it will be modelled with the obje

Global climate change is one of the largest threats faced by biodiversity globally, with a wide range of impacts already observed and greater impacts projected to occur by the end of this century. Early identification of which species are most threatened by climate change is crucial to ensuring conservation action can be taken to prevent species losses. In this thesis I analyse the performance of a wide range of methodologies used to assess the risk to individual species from climate change, finding overall poor agreement between the different methods and validation using historic data sources

Abstract:

Species have responded to recent increases in global temperatures by shifting their geographical ranges poleward and to higher altitudes. As the climate changes in the future, species ranges are predicted to shift out of existing nature reserves. One suggestion to mitigate this effect is to conserve areas which contain a range of microclimates in the hope that species will find refuge in some suitable locations even though the global climate changes. However, such potential conservation strategies require evaluation oftheir likely success before they can be implemented. This thesis addresses t

Global climate change is an important threat to biodiversity and is predicted to be a major driver of wildlife population extinctions throughout the current century. Across a wide range of taxa, a well-documented response to climate change has been changes in species distributions, often towards higher latitudes and altitudes. Species distribution models (SDMs) have been widely used to predict further range changes in future but their use has often focused on discrete geographical areas. Moreover, SDMs have typically been correlative, ignoring biological traits. Here, I use SDMs to project fut

Learners regard Chemistry as one of their most difficult courses at secondary and undergraduate levels, because they have to link several modes of representing matter and their interactions. Phase changes are one of the topics that learners of Chemistry experience problems with. On microscopic level phase changes can be explained in terms of the particulate nature of matter. During a phase change the outward appearance of a substance change, while the substance itself remains the same. In order to learn this concept, learners performed experiments on conservation of mass in an empirical study.

ENGLISH ABSTRACT: Biodiversity refers to the variety of life on earth at all scales of observation. Its persistence underlies ecological and evolutionary processes and is pivotal for the sustenance and future development of human societies through the provision of ecosystem services. Especially since the industrial revolution, anthropogenic land-cover change has placed ever-increasing strain on natural systems through the destruction and degradation of habitat. The Cape Floristic Region (CFR) is a global biodiversity hot spot which contains some of the highest levels of floristic diversity an

Abstract:

Includes bibliographical references.<br>This study uses bioregionalism and bordering as a lens for understanding the construction of Mapungubwe as a transfrontier conservation area and the effects of that process on biodiversity, the local economy and local communities. The main assumption underlying the study is that transfrontier conservation areas are founded on principles of bioregionalism. The study is motivated by three main claims that are advanced in support of the establishment of bioregions across international borders, namely, that transfrontier conservation areas enhance biodiversi

Abstract:

The Namaqualand area in the North Western Cape, South Africa is unique in comparison to other similar semi-arid areas of the world. It has a high biodiversity and endemism and is consequently an area of interest for a growing number of conservation initiatives. Climate plays an important role in influencing the phenology and growth of the vegetation in the area. Remote sensing techniques were used to reveal the vegetation patterns in the greater Namaqualand area and to relate them to climatic variables. To do this we used the normalised difference vegetation index (NDVI) to relate biomass to a

Abstract:

Includes bibliographical references<br>Climate change poses a major threat to living organisms, with maximum temperatures expected to continue to rise over the next few decades. Hot desert environments are particularly at risk because they experience high environmental temperatures, scarce vegetation, low productivity and unpredictable water sources. Endotherms such as birds face the challenge of maintaining a stable body temperature while avoiding dehydration. This study was carried out in the southern Kalahari, in South Africa's Northern Cape, where about 50% of bird species (36 species) dep
