Willow, a deciduous, woody shrub, is a characteristic and often dominant riparian species (Amlin and Rood 2002) that has been unable to successfully regenerate throughout much of its western range, and Yellowstone National Park (YNP) is no exception (Singer et al. 1994, NRC 2002a). The primary objective of this study was to understand growth and maintenance of established willow stands as a community and as individual species following winter browse. These were based on the premises that (1) different levels of herbivory produce varying levels of compensatory growth (Brookshire et al. 2002), (2) different channel types provide diverse hydrologic conditions for vegetation establishment and maintenance (Patten 1998, Castelli et al. 2000), (3) riparian biodiversity is a function of fluvial dynamics and is increased by the degree of hydrologic connectivity of the system (Amoros and Bornette 2002), and (4) the possibility of willow species being either generalist (showing water source shifts) or specialist (availability doesn't influence water source) (Dawson and Ehleringer 1991, Busch et al. 1992, Schwinning and Ehleringer 2001). Site selection and design, and sampling scheme were designed to evaluate biophysical gradients both within and between sites over time. Gradients of biophysical parameters were quantified throughout the growing season. Regressions were used to identify relationships among physical and biological parameters or characteristics. Vegetative communities were compared using Sorenson's similarity index. Ecosystem functions that influence willow presence on the Northern Range include establishment, browse pressure, and maintenance and resilience or their ability to recover. Establishment of willow was a result of availability of their preferred water source while winter decline was a function of location and herbivore preferential selection. Maintenance and resilience were dominated by soil water use in the early season and groundwater use later in the season but with distinct variations between hydrologic systems. Nutrient availability and hyporheic connectivity, essential to dispersing those nutrients among the plant communities, also may influence growth and resilience of willow plants. However, excess or even "acceptable" levels of only one of the physical factors was not enough alone to control dominant plant growth and response to herbivory.

I detta examensarbete skrivet vid Musikproducentprogrammet på Linköpings Universitet har jag efter litteraturstudier om surroundljud och inspelningsteknik undersökt möjligheterna att spela in konsertframträdanden i 5.1-ljud, ett relativt nytt medium för musikinspelningar som är på stark frammarsch. Målet med examensarbetet är att utröna hur detta nya ljud-format kan appliceras vid återgivning av framföranden på scen och vilka tekniker som i så fall kan användas för att uppnå ett tillfredsställande resultat. Metoden som denna rapport baserats på består av två olika delar, en teorisk del samt ett praktiskt moment för att prova de inhämtade kunskaperna. Den teoretiska delen har bestått av litteraturstudier av både tryckta och elektroniska källor. För att ha ett lämpligt material att arbeta med har jag spelat in en konsert med popbandet Weeping Willows som spelade i Hörsalen i Norrköping den 11 november 2005. Sammanlagt 16 låtar spelades in vid detta inspelningstillfälle, musik som sedan redigerades och mixades med 5.1-ljud med hjälp av ljudredigeringsprogrammet Nuendo 3 från Steinberg. Undersökningen visar att det går att uppnå ett tillfredsställande resultat med inspelningar av konsertinspelningar av populärmusik i surroundljud, men det medför också att betydligt fler ljudkanaler behöver hanteras på lämplig inspelningsutrustning, jämfört med stereoinspelningar. Konsertinspelningar i surroundljud ställer högre krav på lokalens akustiska egenskaper, eftersom dessa framkommer tydligare vid återgivning. Kraven ökar också på monitorsystemet vid redigering och mixning av det inspelade materialet för att uppnå en korrekt återgivning hos slutanvändaren.In this essay I have made research concerning the possibilities to record live concerts of popular music in 5.1 surround sound, which is a rather new media for musical recordings. The purpose of the study is to find out how this new format can be applied when reproducing live performances and which techniques that can be used to achieve pleasing results. The method which this essay is based on is divided into two parts, a theoretical part and an empirical project. The theoretical work has been literature studies of both printed and electronic sources. The project I have made to acquire some proper working material were a recording of a live concert by Swedish band Weeping Willows, which made a performance in Norrköping on the 11 of November 2005. Sixteen songs were recorded at this concert, which later were edited and mixed in 5.1 surround sound. The result of the study shows that it is possible to achieve good results when recording live performances in surround sound but it also means that more audio channels have to be handled on suitable recording equipment compared to stereo recordings. Recording of live concerts in surround sound also means higher demands of the locations acoustical qualities, since they are more noticeable when reproducing the recording in surround sound. The demands are also higher on the

Cottonwoods (Populus sp.) and willows (Salix sp.) are generally limited to riparian landscapes in semi-arid regions of western North America. Water availability is a major determining factor for the establishment, growth and survival of these plants. Willows generally occur closer to the stream and at lower elevations than cottonwoods, suggesting reduced drought tolerance and increased flood tolerance. In the present thesis project, three related studies were conducted to investigate this hypothesis. Firstly, tolerable rates of water table decline and the impacts of the corresponding drought stress were investigated by growing cottonwoods and willows under water table decline rates from 0 to 12 cm/d. Willow saplings responded similarly to cottonwood saplings, but willow seedlings were more vulnerable than cottonwood seedlings to rapid rates of water table decline. In the second study, will saplings tolerated elevated water tables of 0 to 7.5 cm below substrate surface and the resulting flood stress for 152 days slightly better than cottonwood saplings. Finally, mature cottonwoods along Willow Creek, Alberta experienced water table decline from 1996 to 1998 due to water pumping in a nearby gravel pit; the water table recovered in 1999. The cottownwoods displayed physiological changes indicating drought stress in 1998 and recovered following restoration of the water table. This confirmed the cottonwoods' reliance on the water table as their primary moisture source. These studies indicate that the spatial separation of willows and cottonwoods may be particularly related to reduced drought tolerance of willows and these display only slightly increased flood tolerance of willos and these display only slightly increased flood tolerances. The studies confirm that both willows and cottonwoods are physiologically dependent on a sufficient riparian water table.85 leaves : ill. ; 28 cm.

PHYTOREMEDIATION OF WEATHERED PETROLEUM IN GROUNDWATER BY ARROYO WILLOWS IN NUTRIENT AMENDED ON-SITE MESOCOSMS
SARAH BRAGG-FLAVAN
A large-scale mesocosm study was conducted to determine if vegetation with willow trees enhances biodegradation and to evaluate the mechanisms of natural biodegradation of weathered petroleum compounds under field conditions. The mesocosms were designed to model conditions at a former oil field where mid-range petroleum distillates were used as a diluent for pumping crude oil contaminated the soil and groundwater at the site with petroleum compounds. Ten mesocosms were constructed at the field site using un-impacted soil and diluent-impacted groundwater from the site. Five of the mesocosms were planted with Arroyo Willow trees native to the field site and the other five served as controls without trees. Since these willow trees are phreatophytes, their roots are capable of consuming water from the water table. A previous study was conducted using these mesocosms, however the willow trees then were in poor condition. In this study, fertilizer was added to the mesocosms to promote healthy growth of the willows. Fertilizer was added equally to mesocosms with and without willow trees to avoid introducing bias. Groundwater was circulated through the mesocosms for two 109 to 126 days runs, while the total petroleum hydrocarbon (TPH) concentrations of the groundwater were measured periodically. Dissolved oxygen concentrations were also monitored in each of the mesocosms to determine if the willow trees had any impact on oxygen transfer to the subsurface.
In the first run without nutrient amendments the trees did not enhance biodegradation. All the mesocosms started with an average TPH concentration of 6.3 mg/L and ended with a concentration of 1.0 mg/L. After this first run, nutrient amendments were added to all the mesocosms, resulting in healthy trees with robust growth. With healthy willow trees, the planted mesocosms resulted in a statistically significant increase in long-term biodegradation of dissolved-phase petroleum compounds. The planted mesocosms resulted in 29 percent more degradation. These results agree with prior lab studies using bench-scale microcosms with media from the former oil field which indicated that TPH concentrations after 100 days were lower in containers with willows or lupines compared to controls without plants. Microtox® toxicity decreased for both planted and control mesocosms, showing no toxic root exudates or by-products.
There are several potential mechanisms of the observed phytoremediation. Terminal restriction fragment analyses showed that the planted mesocosms had different microbial communities than the unplanted mesocosms. Thus, a possible mechanism of the phytoremediation is stimulation of a rhizobial microbial community that biodegrades petroleum compounds. The dissolved oxygen (DO) concentrations were actually lower in the planted mesocosms, possibly due to consumption of oxygen during biodegradation of root exudates. The reduced DO concentrations in the planted mesocosm discounts the possibility that the plants stimulated biodegradation by increasing oxygen transfer to the subsurface. It is not known from these experiments if the petroleum compounds were taken up by the plants or if the plants stimulated bacterial biodegradation. Since it is difficult for plants to uptake non-polar compounds with a high octanol-water coefficient (Kow), it is usually unlikely that plants could uptake petroleum compounds which usually have a Kow > 3. However, the log Kow of the dissolved phase diluent determined in this research was only 0.14. Although the mechanism by which the willow trees increased biodegradation was not elucidated, this study demonstrated that phytoremediation of the polar and hydrophilic weathered petroleum compounds was successful.
Column chromatography was used to fractionate petroleum compounds extracted from the groundwater into aliphatic, aromatic and polar components so that biodegradation of each of these fractions could be determined independently. The first mesocosm experiments showed that regardless of the presence of trees, there was a decrease in TPH concentration for all three fractions. The overall unfractionated biodegradation rates averaged 41 ug/L/day over this experiment, and the biodegradation rate of the polar fraction was similar at 40 ug/L/day. In comparison, the biodegradation rates of the aliphatic and aromatic fractions were considerably lower at 1.2 and 2.6 ug/L/day, respectively.

Deciduous woody vegetation (DWV) in Yellowstone's northern range is a rare, but important habitat type. Including willow, alder, aspen, and cottonwood, DWV was limited in height and areal extent since the early 1900s. Since the mid-1990s; however, DWV has increased in height and areal extent in some locations. Previous studies regarding DWV change have focused on quantifying change in vegetation growth in areas of limited extent and none have quantified increased DWV growth at the scale of the landscape. Furthermore, no studies have evaluated the implications for increased growth of DWV for wildlife in the region or how DWV species themselves may influence rates of growth. In this thesis I evaluate change in DWV within wetland and riparian areas using aerial photographs from 1991 and 2006. I also investigate how an increase in willow, the dominant component of DWV in the region, has likely influenced bird diversity. Finally, since willow species vary with respect to genetic limitations on growth and reproduction that in turn may influence observed patterns of growth; I examine willow species composition across the northern range. Results of the air photo interpretation revealed a 170% increase in DWV. Most plots that increased did so by recruitment rather than densification; however, DWV was difficult to detect below 100 cm indicating that the number of plots increasing by recruitment may have been overestimated. Bird community variables were examined in three willow growth conditions: height suppressed, recently released, and previously tall (tall prior to observed increase in growth). I found that willow structure generally increased in complexity from structurally simple height suppressed willows to structurally complex previously tall willows and that this allowed for greater bird richness, abundance, diversity, and the abundance of several willow dependent bird species. I also found that willow species composition was similar and diverse between the released and previously tall condition, but that the suppressed condition was dominated by a singe species. I conclude that increased DWV has allowed for greater bird diversity in the northern range and that increased willow growth in the suppressed condition may be influenced by species composition there.

South Africa‟s social, economic and political landscape was shaped by a long and bitter history of land reform and dispossession. It is against this background that the land reform policy was introduced. According to the Department of Land Affairs the objective of land reform was to alleviate poverty and improve the livelihoods of the poor. Since the introduction of the land reform policy in South Africa, there is no empirical evidence that land reform is improving the livelihoods of its beneficiaries and other affected groups such as farm workers. However government focus has been on how much land was redistributed to the previously disadvantaged and dispossessed. The study sought to assess the impact of land reform on the livelihoods of farm workers with specific reference to the Oaks/Willows Citrus farm in Maruleng Local Municipality, Limpopo Province. The study focussed on whether this land reform project achieved its intended objective of improving livelihoods and alleviating poverty. The following groups participated in the study: The farm workers, project committee members, representative of the traditional leader and a representative of the Department of Rural development. The study found that the livelihoods of the farm workers had not improved after the implementation of this land reform project. The study also revealed that government intervention with post settlement support programmes to monitor progress or offer assistance with regard to farm management and extension services, is very important to ensure that land reform projects achieve their intended objective of reducing poverty and improving the livelihoods of the poor.

The purpose of this thesis is the determination of a minimum market price for Short-Rotation Forestry (SRF) willow biomass grown in monoculture and windbreaks in Quebec and Ontario. Full cost budgeting was used and developed on a Microsoft Excel spreadsheet. Harvest cycles of 3 and 4 years for monoculture plantations, and 8 years for windbreaks were investigated. Estimates for establishment and other preharvest costs were obtained from mid-sized (5 hectares) commercial SRF willow plots in Quebec and Ontario.For the monoculture plantations, irrespective of cycle length, and using the base case figures, the final delivery cost of willow biomass ranged between 74-126 $/odMg and 63--109 $/odMg based on current and projected costs respectively. These hold for yields between 7 and 11 odMg/ha/yr. Moreover, the 4-year cycle was revealed to be more economically efficient than a 3-year cycle. Along with yield, the main cost factors affecting the economics of SRF monoculture plantations are: harvesting, transportation to a processing plant, land lease management. For the two major energy markets, ethanol and electricity production (biomass in replacement of coal), SRF willow biomass in monoculture plantations does not appear to be a viable feedstock given present technology and yields. In the short run, a more promising outlet for willow biomass is space heat production for small buildings, farm complexes, etc. In this market, many potential buyers can afford to pay a higher price for biomass than ethanol or electricity utilities.
In the windbreak system, biomass could be produced for between 44 and 68 $/odMg, assuming that yields between 12 to 20 odMg/ha/yr can be achieved. At this price, windbreak biomass is not a competitive feedstock for ethanol or electricity generation, but is attractive for space heat production. (Abstract shortened by UMI.)

In this thesis, I explore the works of Kenneth Grahame in light of what some critics have deemed “literary paganism”. I argue that Grahame employs certain “pagan” tropes in order to launch a critique of modern culture. Grahame upholds a classical vision of leisure that rejects the ideology inherent to urbanization. His critique of modernity relies on a literary persona indicative of an alternative attitude to that of the middle class fin de siècle urban culture. His short stories add to this critique in their presentation of childhood as a pre-converted pagan existence which en-kindles a sense of disappointment with routinized adult life in the modern city. The Wind in the Willows embodies Grahame's vision of true leisure which is depicted in both the River Bank animals and their wetland ecosystem itself. By paying close attention to the pagan themes in Grahame’s writing, we gain a comprehensive view of his often misunderstood body of work.

The Savi’s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species’ habitat requirements is essential to maintain a viable population and design action plans. This study, the first of its kind in Sweden, examined the vegetation structures in occupied territories of Savi’s Warblers at Lake Tåkern, the country's stronghold for the species. The species was found to be associated with the outer edge zones and fragmented areas of reed (Phragmites australis). Occupied territories differed from randomly chosen unoccupied (control) territories by having a thicker layer of reed litter, and on average more bushes of Willow (Salix spp.) present. Reed density and reed height did not differ from areas that lacked Savi’s Warblers. Territorial and displaying males were concentrated in two edge areas with a mosaic of reed islets where the territories remained relatively close together.

Carbon storage was compared between two perennial biomass energy systems, namely switchgrass (Panicum virgatum L.) and short-rotation willow Salix alba x glaffelteri L.) at 2 adjacent sites, and further compared with a corn cultivation, a 20-year-old abandoned field, and a mature hardwood forest, in southwestern Quebec. Aboveground carbon results indicated that switchgrass and corn had significantly greater carbon levels than willow at the less fertile site, but no significant differences were detected at the more fertile site. Root carbon results indicated that corn had significantly lower carbon levels than both perennial systems to a depth of 30 cm at both sites. However, switchgrass had significantly greater root carbon levels beyond 30 cm compared with willow and corn, and beyond 45 cm compared with the forest and abandoned field. These findings indicate that deep-rooted perennial grasses such as switchgrass have the potential to sequester carbon at deeper soil layers. Soil carbon results showed that at the more fertile site, willow was associated with significantly greater soil carbon levels than switchgrass. Moreover, both perennial crops had soil carbon levels that were greater than for corn, the abandoned field, and the forest. In contrast, at the less fertile site, no significant differences in soil carbon were detected between the various plant systems examined. The results of this study suggest that the perennial energy crops used, when grown on relatively fertile soils, have the potential to substantially increase soil carbon levels compared with conventional agricultural and/or forest systems. Consequently, when these crops are grown on less fertile soils, their added advantage of increasing carbon storage is lost.

Definisanjem parametara akumulacije, otpornosti i tolerantnosti različitih klonova vrba na prisustvo kadmijuma u podlozi, kao i uspešnosti primene limunske kiseline kao helatora u procesu asistirane fitoremedijacije, mogao bi se identifikovati klon (ili klonovi) pogodan za dekontaminaciju zemljišta zagađenog kadmijumom. Da bi se postigao cilj istraživanja biljke su gajene u polu-kontrolisanim uslovima tokom 3 meseca. Eksperiment je podeljen u dve faze (dve godine istraživanja),zasnovane na razlikama u metodološkom pristupu. Tokom prve godine limunska kiselina je dodata jednom, dok je tokom druge druge godine aplikacija ovog helatora vršena u tri ponavljanja. U radu je analizaran sadržaj i distribucija Cd u zemljištu irazličitim biljnim organima (koren, izdanak, mladi i stari listovi); uticaj Cd i limunske kiseline na morfometrijske parametre: visina i prečnik izdanka, masa i površina listova, broj listova, masa i zapremina korena; na fotosintetičke karakteristike: intenzitet fotosinteze, intenzitet transpiracije, stomatalnu provodljivost, intercelularnu koncentraciju CO2, efikasnost korišćenja vode, koncentraciju fotosintetičkih pigmenata; na mineralnu ishranu i distribuciju makronutrijenata u biljkama (sadržaj azota, fosfora i kalijuma); na sadržaj aminokiseline prolina i cisteina; na aktivnost antioksidativnih enzima (katalaza, askorbat-peroksidaza, gvajakol-peroksidaza), kao neezmiskih antioksidanata poput sadržaja redukovanog glutationa i tiola. Dobijeni rezultati su ukazali na genotipsku specifičnost analiziranih klonova vrba u procesu fitoremedijacije u zavisnosti od primenjenog tretmana, doze Cd i prisustva limunske kiseline. Toksično dejstvo nije bilo jasno uočljivo na morfološkom nivou, dok su primenjeni tretmani signifikantno uticali na fiziološko-biohemijske procese u biljkama. Sa povećanjem sadržaja Cd u biljkama je utvrđena tendencija smanjenja intenziteta fotosinteze, transpiracije, kao i efikasnosti koršćenja vode, dok je primena limunske kiseline ublažila štetan efekat ovog teškog metala, što je registrovano nakombinovanim tretmanima. Kao odgovor na akumulaciju Cd u biljnom tkivu utvrđenaje promena aktivnosti antioksidativnih enzima, kao i neezimskih komponentiodbrambenog sistema zaštite. Pored toga, u radu je utvrđeno da primena limunske kiseline utiče na usvajanje, akumulaciju i toleranciju vrba na prisustvo Cd, te rezultati ove studije imaju praktičan značaj u usavršavanju tehnika fitoremedijacije i dekontaminacije zagađenih područja.The role of citric acid on morphological, physiological and biochemical characteristics of selected willow clones (Salix spp.) grown in soil with moderately polluted cadmium (Cd) was presented. The aim of this study was to determine the Cd accumulation, translocation and tolerance of different willow clones, as well as the influence of citric acid as a chelator in the assisted phytoremediation process. In order to achieve this goal, plants were grown in semi-controlled conditions for 3 months. The experiment was divided into two phases (two years of research), based on differences in the methodological approach, regarding the application of citric acid. During the first-year experiment, citric acid was added once, while in the second year the application of this chelator was performed in three repetitions. The analyses included: the accumulation and distribution of Cd in soil and various plant organs (root, stem, young and old leaves); influence of Cd and citric acid on morphometric parameters: stem hight and diameter, number of leaves, biomass and area of leaves, biomass and volume of the root; on photosynthetic characteristics: net photosynthetic and transpiration rate, water use efficiency, stomatal conductance, intercellular concentration of CO2, concentration of photosynthetic pigments; on mineral nutrition and distribution of macronutrients in plants (nitrogen, phosphorus and potassium content); on the content of the amino acid proline and cysteine; on the activity of antioxidant enzymes (catalase, ascorbate peroxidase, guaiacol peroxidase), as non- enzymatic components such as reduced glutathione and thiol content.The obtained results indicated the genotypic specificity of the analyzed willow clones in the phytoremediation process, depending on the treatment applied, the Cd dose, and the presence of citric acid. The toxic effect was not evident on the morphological level, while the applied treatments showed a significant influence on the physiologicalbiochemical processes in the willows. The net photosynthetic rate, transpiration rate, as well as, water use eficiency showed decreasing with increasing Cd concentration in plant tissue, while the application of citric acid mitigated the harmful effect of this heavy metal, which was registered on combined treatments. In response to the accumulation of Cd in plant tissue, a change in the activity of anti-oxidant enzymes, as well as nonenzymatic components of the defense system has been established. In addition, theapplication of citric acid showed the promotion role on the absorption, accumulation and tolerance of willows grown in moderately polluted soil cadmium, which has a practical significance in the improvement of phytoremediation techniques and decontamination of polluted soil.

Municipal treated wastewater entering rivers contain biologically active pharmaceuticals capable of inducing effects in aquatic life. Phytoremediation of three of these pharmaceuticals and an herbicide was investigated using Sandbar willow (Salix exigua) and Arabidopsis thaliana. Both plants were effective at removing compounds from solution, with removal of 86% of the synthetic estrogen, 17α-ethynylestradiol, 65% of the anti-hypertensive, diltiazem, 60% of the anti-convulsant, diazepam (Valium®), and 51% of the herbicide atrazine, in 24 hours. Distribution of compounds within roots and shoots, in soluble and bound forms, differed among compounds. Uptake and distribution of pharmaceuticals within the study plants confirmed pharmaceutical behaviour can be predicted based on a physiochemical property, their octanol-water partitioning coefficients.
An effective method for detection of 17α-ethynylestradiol within surface water using solid phase extraction and gas chromatography-mass spectrometry was developed. Previously unreported breakdown of 17α-ethynylestradiol into another common estrogen, estrone, during preparative steps and gas chromatography was resolved.xv, 216 leaves ; 29 cm.

Ideas that are migrating from Canada are already guiding advocates who seek greater judicial and constitutional recognition of Aboriginal and Torres Strait Islander peoples. However, there is a need for a conceptual framework through which to approach the lessons that can be learned from Canada in this area. Inspired by The Migration of Constitutional Ideas, an edited work by Sujit Choudhry, in this thesis I argue that by thinking about the migration and transplantation of foundational ideas and by differentiating between four ‘modes’ of migration (arguments of counsel, judicial determinations, academic critique and constitutional reform deliberations), it is possible to better understand some of the processes that are at play. In particular, by adopting the terminology of the ‘migration’ and ‘transplantation’ of ‘foundational’ ideas, I aim to demonstrate that it is dangerous to transplant foundational ideas, whether derived from the common law or constitutional law, without other ideas (particularly in relation to implications) also migrating.
This thesis is a response to two distinct but related topics: ‘Topic 1 — The Potential for Judicial Recognition of Indigenous Self-Government Rights: The Migration of Foundational Ideas from Canada to Australia’ and ‘Topic 2 — Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples, the Race Power and an Anti-Discrimination Guarantee: Contemplating Canadian Approaches to Equality’.
Through these two topics I examine two of the recognised modes of recognition — judicial and constitutional — and focus on two discrete types of recognition — self-government and non-discrimination — and the lessons that can be learned from Canada.
In response to the first topic I consider the extent to which foundational ideas are migrating from Canada to Australia in the field of Indigenous self-government rights and whether these ideas could be used in Australian courts. In response to the second topic I consider the extent to which Canadian experiences may assist when exploring the potential implications of prohibiting discrimination in the Australian Constitution and when examining the various options that are available. As far as the migration of foundational ideas from Canada is concerned, in Topic 1 my starting point is to consider what could be learned from the Canadian jurisprudence in order to understand the ideas that have migrated or could potentially migrate to Australia. In contrast, in Topic 2 I start with an appraisal of the lack of recognition of Aboriginal and Torres Strait Islander peoples in the Australian Constitution and the perceived problems with s 51(xxvi) (the ‘race power’), and in so doing I consider what benefits (modified) Canadian transplants may offer, if any.

The influence of streambank location and timing of herbivory on success of
planted Booth's willow (Salix boothii Dorn) cuttings along a Rosgen C5-type stream
in an eastern Oregon meadow was determined. Willow cuttings were planted on two
morphological locations (i.e. point bar and floodplain) in May of 2002 and 2003.
Gravimetric soil moisture and depth to water table data were collected periodically on
each planting location during the growing season, May through September, in both
years. Three grazing treatments, early season, late season, and none (control) were
conducted. Percent survival, leader density, and number of browsed leaders of
willows were recorded prior to and after each grazing treatment, as well as stubble
height of forage species. Simple linear regression was used to determine if a
relationship between residual stubble height and percent willow browse existed.
Multiple linear regression was used in an attempt to develop a predictive equation for
percent browse based on pre-grazing stubble and willow heights.
It was hypothesized that depth to water table and percent soil moisture
throughout the growing season would significantly influence willow survival and
growth; that survival would be higher on point bar locations; and that willows would
be browsed at different intensities according to season of grazing.
Soil moisture content at point bar locations was greater than that of floodplain
locations for the majority of the growing season in both years. In 2003, groundwater
levels were higher on point bar than floodplain locations from May through
September. Willow survival was higher for point bar locations than floodplain
locations, in both years, regardless of grazing treatment.
Willows were browsed more intensively later in the growing season. Results
from the simple linear regression suggest that percent browse of willows was related
to the residual stubble height, but did not explain the variability observed. An attempt
to develop a predictive equation, i.e., expected browse based on pre-grazing stubble
height, was made, however no apparent relationship between the willow height,
stubble height, and percent browse was found. Grazing treatment did influence
willow survival; survival on floodplain locations within the late grazing treatment was
less than that of the ungrazed floodplain locations.
Our results suggest that planting willows in locations where the planting depth
remains within 40 cm of the groundwater depth will increase planting success.
Protection from grazing for at least the first year of growth is recommended for
optimum planting survival; grazing early in the season is more favorable to survival
than grazing later in the season.Graduation date: 2004

Kenneth Grahame’s The Wind in the Willows not only has long been regarded as a part of the canon of children''s classics, but also has been widely read by children and adults. This thesis will ask why the book has been claimed to be part of the canon of children’s classics and address the problem of allegorical genre in a book for children through an analysis based on the theory of Mikhail Bakhtin. Bakhtin explores the idea of “heteroglossia” through which the dialogical opposition of verbal-ideological centripetal and centrifugal forces are working at the same time in the novel. From Bakhtin’s concept of heteroglossia, an artistic work like The Wind in the Willows not only shows the representation of multi-voices concealed within this children’s book, but also shows the representation of the dialogical tension between the centripetal force of the traditional pastoral and the fable as opposed to the centrifugal force of the adventuring child voice in The Wind in the Willows. That is, although the pastoral and the fable are shown to have oppositional forces within them in the allegorical doubling of voices as used in Grahame’s novel, they represent the traditional literature and literary interpretation of the educated adult to be decentered by the child voice. In Chapter One, I introduce the theories I use in this thesis. In Chapter Two, I discuss the subjects of Mobility and Domesticity in Victorian England through an analysis of the structure of the process of leaving and returning home using Bakhtin’s concept of centripetal and centrifugal forces. In Chapter Three, I explore the problem of the pastoral allegory and the fable allegory in The Wind in the Willows, which brings up one question from the main thesis: is this work a pastoral and fable allegory with such a double meaning or an adventure for children’s literature? Thus, with the doubling of voice of the pastoral and the fable, this book retains an ambiguous position as a children’s book. In Chapter Four, I discover that the uniqueness of Grahame’s The Wind in the Willows as a child’s book depends not upon ambiguous meaning of the pastoral and fable but the adventure story with its own heteroglossic features. Ultimately, in my conclusion, I explain how The Wind in the Willows not only offers the readers a text concealing multi-voices, but also shows how the dialogical tension even strengthens the innocence of the child voice amid the pastoral and the fable double voices. Therefore, we can read and interpret this child’s book from different perspectives, but it is the emergence of the child voice that makes the work a children’s book.

Повний текст джерелаАнотація:
This thesis explores the hydrological factors that may contribute to the observed distribution
patterns of invasive willows (Salix) and native trees (Eucalyptus camaldulensis, E. largiflorens and
Acacia stenophylla) along the Lower River Murray (LRM) in southern Australia. An initial survey,
establishing the diversity and flowering biology of Salix taxa was carried out to ascertain the extent
of invasion, and the likelihood of hybridisation, which may accelerate invasion. S. babylonica,
S. fragilis, S. × chrysochoma and S. × rubens occur in the study region, each represented by a single gender. None were present on floodplains, but the most dominant taxon, S. babylonica,
occurred along the entire length of the main channel. No seed or seedlings were observed; hence
reproduction is likely to be asexual.
More detailed survey work was then carried out to characterise the distribution patterns of the
dominant S. babylonica and co-occurring natives (Eucalyptus camaldulensis, E. largiflorens and
Acacia stenophylla) along a hydrologic gradient produced by the extensive weir system in the
LRM. In weir pools, variation in daily water levels of weir pools is low (± 0.1 m) immediately
upstream of the weir, but higher immediately downstream (0.2-1.0 m daily). The distribution of
natives was uniform across weir pools, while S. babylonica was more abundant above weir
structures, suggesting low tolerance to variable water regimes.
Hypotheses relating to the observed distribution patterns were then tested experimentally on
juveniles of the S. babylonica, E. camaldulensis and A. stenophylla. The experiment was carried
out in outdoor ponds using an orthogonal design, with four elevations in relation to water level (-25
cm, 0 cm +25 cm, + 50 cm) under each of three water regimes. Experimental water regimes
manipulated the magnitude of daily water level changes (static, 0 m dayˉ¹ ; moderate, ± 0.05 - 0.15
m dayˉ¹; high, ± 0.2 -0.5 m dayˉ¹) to mimic typical hydrological conditions across weir pools in the
LRM. Final biomass and mean relative growth rates (S. babylonica, 0.0403 ± 0.002 g mˉ²dayˉ¹ A.
stenophylla, 0.0249 ± 0.0017 g m ˉ² dayˉ¹; E. camaldulensis, 0.0204 ± 0.0016g mˉ² dayˉ¹) of all 3
species were unaffected by water regimes (i.e. water fluctuations), but were affected by elevation.
Survival of both S. babylonica and A. stenophylla was lowest at low elevations where inundation
was high. At higher elevations (+25 cm, +50 cm) the RGR of S. babylonica juveniles was much
higher than the native juveniles.
To test if the persistence of adults of each species along hydrologic gradients were associated with
differing tolerances to water deficits and water use characteristics, S. babylonica and native species
were examined under typical hydrological conditions in the field and during an unusual drawdown.
S. babylonica occurring at the lowest elevations on riverbanks, had the least negative predawn shoot water potential (ψpredawn), followed by the natives, which were at higher elevations.
A. stenophylla had the lowest stable carbon isotope ratio (δ¹³C) values (by 1.7 ‰) on the riverbank;
suggesting more profligate water use than S. babylonica and E. camaldulensis. However, all
riverbank trees had significantly less negative ψpredawn and lower δ¹³C than native trees on
floodplains, consistent with higher water availability on riverbanks. The position and stable oxygen
isotope ratio (δ¹⁸O) values were consistent with riverbank S. babylonica sourcing their water
directly from the river or from shallow soil-water sources (<0.25 m). In floodplain habitats, depth
to water was > 2.5 m, and groundwater was 5 times more saline (4.97 ± 0.88 dS mˉ¹) than river-water.
Native trees with deep roots, the ability to lower water potentials and alter water use
efficiencies may be at an advantage in this habitat relative to S. babylonica.
Extreme low flows in the LRM, over a 6-month period, provided an opportunity to assess how
S. babylonica and E. camaldulensis responded to a river-water drawdown. During the drawdown,
river-water levels fell at a rate of ~2 – 2.5 mm dayˉ¹ and dropped to a minimum of 0.42 m below
the designated pool level. S. babylonica and E. camaldulensis maintained high ψpredawn across the
drawdown period, most likely because riverbank soil water availability was not limited; as depth to
water table only decreased marginally (≤0.15 m) and soil water content and soil water potential
were high (<1.1 MPa). However, an above average rainfall in February 2003 significantly
increased soil water potential in the upper 0.25 m of the riverbank, which correlated with a
significant increase in ψpredawn in E. camaldulensis, suggesting they were able to use shallow,
precipitation derived soil-water sources whereas S. babylonica were not. Also under hot, dry
conditions, S. babylonica had higher transpiration rates and lower instantaneous water use
efficiencies than co-occurring E. camaldulensis. This suggests that S. babylonica may consume
larger volumes of water per unit leaf area than natives, if access to water is maintained.Thesis (Ph.D.) - University of Adelaide, School of Earth and Environmental Sciences, 2010

Culture types in Pacific Northwest archaeology are characteristic artifact assemblages distinguishing different prehistoric periods. Assemblages indicate a culture type transition during the 2,630 BP–270 BP occupation of Willows Beach (DcRt-10), southeastern Vancouver Island. Faunal remains could reveal links to subsistence patterns, following Croes’s theory that culture type change reflects subsistence intensification.
Five dated DcRt-10 faunal assemblages underwent taxonomic and size classification, weighing and MNI calculation. Vertebrate weight and NISP percentages were compared between stratigraphic units associated with the later Gulf of Georgia and earlier Locarno Beach culture types. The youngest assemblage contains a smaller proportion of land mammal bone, suggesting increased sea mammal, fish, and bird procurement. Faunal remains also suggest a greater variety of taxa exploited over time.
Faunal assemblages suggest that culture type change at DcRt-10 is the product of subsistence change, increasing knowledge of the culture historic sequence of this region.

Повний текст джерелаАнотація:
Knowledge of the reproductive and dispersal dynamics of invasive species is central to designing control strategies that minimise local population growth, limit range expansion and reduce the likelihood of reinfestation. Molecular ecological methods in plant population studies has allowed a greater ability to quantify ecological processes such as mating patterns and dispersal which are hard to measure with traditional ecological approaches. Such approaches would be beneficial in the management of environmental weeds to provide information on reproductive and dispersal dynamics that can be used in the development of more effective scale-appropriate management strategies. Willows are aggressive exotic components of many river systems in south-eastern Australia. Current control efforts for the most highly invasive willow species, Salix cinerea, are extensive, costly and not always successful due to rapid post-removal reinfestation. A survey of populations in the Ovens River catchment of south-eastern Australia was undertaken to determine the reproductive ecology, catchment scale variance in population fecundity and dispersal dynamics within and between populations of S. cinerea. The species was found to be predominately insect pollinated but can exhibit wind pollination. Mean seed production was found to be higher than 300,000 seeds per tree across sites and years and is driven by tree size and flowering effort. Predictions of seed production at sites across the study catchment based on population and tree size and flowering effort showed that removing the top 20% of seed producing sites would result in a reduction in catchment seed set of over 50%. This high reproductive output combined with high initial germination rates, above 95%, gives the species the potential to reinfest cleared areas and expand its range. Microsatellite-based paternity analysis was used at four sites to ascertain the relative frequency of within versus between population mating events and identify the variation of male reproductive fitness. Observed patterns of within-site mating dynamics have highlighted a highly skewed male fitness distribution with a small number of fathers being responsible for a large proportion of successful fertilisation events. Genetic profiling of populations in surrounding rivers allowed identification of the most likely pollen and seed sources to give an estimate of the scale of dispersal. Results show that 60% of pollen and 50% of seed is moving more than 15 kilometres and a small amount travelling over 30 kilometres. These results suggest control of propagule pressure will be important for preventing future invasion. This may be attained by clearing high density sites that have the greatest reproductive output; subsequently targeting large trees at sparse and remote sites will have the greatest success in reducing propagule pressure. Reproductive dynamics were found to be heavily reliant on inter-site pollen and seed movement. Extensive pollen and seed dispersal was found among sites and among rivers across the catchment. These results suggest that future control efforts should emphasise removal of large high fitness individuals and populations with high reproductive output as well as spatially coordinating control activities across sites so as to account for inter-site reproductive dynamics.

Mycorrhizae improve plant growth and ecosystem sustainability by forming a symbiotic association with higher plants including the economically important willows (Salix spp.). With the recognition of the importance of mycorrhizae in terrestrial ecosystems, inoculation of plants with mycorrhizae is becoming a common practice in agricultural and land reclamation industries. However, little information is available on important ecological parameters such as soil aggregation, soil organic carbon content (SOC) and mycorrhizal communities associated with willow rhizospheres in response to mycorrhizal inoculation in willow systems. The main objectives of this research were to explore how commercial mycorrhizal inoculation of willows impacts (1) percent water-stable soil aggregates (%WSA); (2) indigenous arbuscular mycorrhizal fungi (AMF) and ectomycorrhizal fungi (EMF) community composition associated with different size soil aggregates; (3) SOC, and (4) willow growth. These objectives were examined under both greenhouse and field conditions.
Using molecular approaches, we observed the existence of spatial variability in indigenous AMF communities among different soil aggregate size classes. This spatial variability varied with type of soil and could be reduced by inoculating with a commercial AMF inoculant. The indigenous EMF diversity was low and did not show spatial heterogeneity among soil aggregates, but it did vary with soil type. In addition, other parameters, including %WSA, SOC within the willow rhizosphere, and willow plant growth also varied by soil type and changed in association with commercial mycorrhizal inoculation.
In the field experiment, soil extracts from willow nursery soil had comparable plant growth promotion with commercial mycorrhizal inoculation, and altered the AMF community associated with bulk soil and soil aggregates in the willow rhizosphere. These results suggest that historically superior willow growth in the willow nursery soil could be due to pre-existing soil microbiological factors.
Overall this research indicates that AMF and EMF inoculation has the potential to influence the composition of the AMF community, but had little influence on the composition of the EMF community in the systems tested.Natural Sciences and Engineering Research Council of Canada

This diploma thesis deals with the cultivation of fast-growing wood and concentrates on the influence of particular factors like e.g. location, agrotechnology and fertilizers, which have a crucial impact on the phytomass production. Moreover, the thesis evaluates the economic efficiency of this type of sustainable energy ressource, which can be a source of local business. Introductory theoretical chapters describe essentials rules of the cultivation of fast-growing wood. Furthermore the thesis presents general information in this field and proposes suitable wood clones. In addition, the thesis outlines the process of choice and preparation of the agricultural parcel, the usage of various fertilizes, herbicides and agrotechnology. The applied core characterises the business case itself. The primary research compares financial investment and its return of two examined agricultural parcels under the prerequisit of suitable choice of location and agrotechnology. A trail phase depictes the cultivation of fast-gworing wood and discuss presumptions for succesfull business. This thesis is mainly based on primary research. The acquired data are further analyzed and the final chapter attempts to outline the results and suggest measures.

My dissertation offers a new look at how women authors used popular genres to negotiate their economic, artistic, and sexual autonomy, as well as their national and imperial identities, in the context of the changes brought by modernity. As medical science and popular media attempted to delineate women’s sexual natures, Sylvia Townsend Warner, Winifred Holtby, Kate O’Brien, and Molly Keane created narratives which challenged not only psychoanalytic proscriptions about the need for sexual satisfaction, but traditional ideas about women’s inherent modesty. They absorbed, revised, and occasionally rejected outright the discourses of sexology in order to advocate a more diffuse sensuality; for these writers, adventure, travel, independence, creativity, and love between women provided satisfactions as rich as those ascribed to normative heterosexuality. I identify a history of queer sexuality in both Irish and English contexts, one which does not conform to emergent lesbian identity while still exceeding the limits of heteronormativity.text
