▼ A mapping study using remote sensing software called ENVI was conducted utilizing four software algorithms to investigate whether these techniques could accurately classify habitat types and vegetation communities along West Bay of the Galveston Bay Ecosystem from color infra-red (CIR) imagery. The algorithms were used in a small-scale study to investigate which of these techniques could most accurately distinguish habitat types and vegetation communities from the imagery at a site specific location. The most accurate algorithm of the four was used in a large-scale classification study in which entire images were classified utilizing the same data from the small-scale study. Regions of interest (ROIs) were used within ENVI to specify areas of interest within each image that was classified. The locations of ROIs were recorded using a GPS prior to classification, then each was added into ENVI as data points, and each ROI polygon was digitized according to its respective pixel color. Once all of the ROI polygons were completed, each software algorithm was employed. After classification, each habitat type and vegetation community was ground-truthed in order to verify the accuracy of the algorithms. The position points were added as ground truth points within ENVI and an accuracy matrix was assessed. The technique with the greatest averaged accuracy within the smallscale study was selected for the large-scale study. The ROIs and ground truth points used in the smallscale study were used again in the large-scale study. The small-scale study concluded that the Parallelepiped algorithm produced significantly less accurate classifications than the other three. Although the Mahalanobis algorithm was not significantly different from the other two algorithms, it yielded the highest overall average accuracy and was used in the large-scale study. In both the small-scale and large-scale studies there was no significant difference in the two different years of aerial imagery and there were no significant differences in accuracy for locations. None of the software algorithms were accurate at classifying habitat types and vegetation communities using the imagery. The accuracy for the Mahalanobis algorithm was less than 60%. Inaccuracies were largely due to overlapping spectral signatures among habitat types and vegetation communities. Advisors/Committee Members: Webb, James W.

▼ Coastal marshes on the Gulf Coast of Texas are an important transition zone between the ocean and land, acting as an ecological buffer and providing invaluable ecosystem services to people and the surrounding environment. Accelerated erosion threatens the stability of these regions and a greater understanding of the interacting processes is vital to the preservation of coastal marshes. The central objective of this study is to evaluate the impacts of wave energy, vegetation, and soil properties on coastal marsh edge erosion. To accomplish this, the first objective was to quantify tidal marsh edge erosion across temporal and spatial scales using TLS. The second objective was to evaluate the relationships between marsh edge erosion and incident wave energy. The final objective was to assess the correlation between vegetation roots and marsh edge erosion as well as the correlation between soil properties and marsh edge erosion. The study area is on an eroding edge of a salt marsh wetland known as Anchor Bay, located at the terrestrial-aquatic interface of Galveston Island and West Bay specifically, between Melager Cove and Oxen Bayou. Galveston Island is a barrier island on the Texas Gulf Coast, located about 50 miles southeast of Houston, Texas, U.S.A. Many methods were used to accomplish the objectives including LIDAR and photographic surveying, point cloud change analysis, wave modeling, image classification and soil analysis for bulk density, percent organic matter, and sediment grain size. Overall, lateral marsh edge erosion at the study site for the duration of the study was relatively large with greater than 1 meter of erosion observed at the study site in a 318 day period. Wave heights, as driven by wind direction and speed, affected the erosion at the study site. The site was prone to greater erosion when winds blew from the east-northeast to the north directions, and from the north-northwest to the west directions. While root concentration did not play an apparent role in preventing erosion, soil properties did have some influence on erosion.

▼ The structure and function of coastal marshes results from a complex interaction of biotic and abiotic processes that continually influence the characteristics of marsh vegetation. A great deal of research has focused on how tidal processes influence vegetation dynamics along the Atlantic coast, but few studies have investigated the influence of similar processes in the marshes along the Gulf of Mexico. This study aims to identify the characteristic vegetation assemblages of the coastal marshes bordering the East Bay of Galveston Bay, Texas, and identify if elevation, inundation frequency and burning frequency are important to their structure. To identify characteristic vegetation assemblages, hierarchical cluster analysis was used. The cluster analysis resulted in seven statistically different vegetation assemblages that were used in diversity analysis and classification and regression analysis (CART) as dependent variables. Diversity measures were calculated at both the plot and assemblage scale using Shannon's diversity index and species richness. The resulting diversity measures were used as predictor variables in the CART analysis as well as regression analysis. Hydrologic modeling was accomplished using Mike 21, a flow and wave simulation model, along with a geographic information system (GIS), to model hourly inundation frequency at each of the sampled plots. The inundation frequency was then used as a predictor variable in the CART analysis and regression analysis. This study found that the main factor contributing to species richness was elevation. Vegetation assemblages at high elevations generally had high diversity, and assemblages at low elevations had lower diversity. Elevation and inundation frequency are inversely related, and the strong correlation between species richness and elevation also assumes that inundation frequency is important in structuring the marsh. Burn frequencies had no influence on diversity in general, but more frequent burning did result in monospecific stands of Spartina patens at Anahuac NWR. Advisors/Committee Members: Cairns, David M.

Monitoring and maintaining the health of coastal wetlands is a global concern. The greatest threat to coastal wetlands in the Great Lakes Basin are anthropogenic removal and enrichment. The coastal wetlands in Georgian Bay are relatively undisturbed by humans, but face disturbance caused by reduced annual water-level fluctuations. Since these wetlands are critical habitat for many fish, bird, amphibian, and reptile species, many efforts to accurately monitor and maintain their health have been put into place. Recently, these wetlands have been experiencing an abrupt (~1 m) transition to higher water levels, following 14 years of sustained lows, which allowed trees and shrubs to invade the meadow vegetation zone. This sustained water-level pattern has never occurred in this region before, offering the unique opportunity to study wetlands undergoing a transition, where areas of 10+ years of upland plant species growth was inundated and became part of the wetland habitat. This thesis first investigates how this change in water level affects the distribution of meadow, emergent, floating, and submerged vegetation both in physical space and area. The second chapter of this thesis presents long-term water quality, macrophyte, and fish community monitoring using ecological indices. Water quality and macrophyte indices are robust enough to monitor wetlands undergoing a transition; however, issues arise in the calculation of the wetland fish index, as the changes in macrophyte distribution described in Chapter 1 impact the ability to replicate community sampling using fyke nets. The research done throughout this thesis is highly beneficial in adding to the limited knowledge of key factors impacting macrophyte community shifting. This work also identifies water-level scenarios where managers must adjust sampling protocols to succeed in effectively sampling wetland fish communities.

Thesis

Master of Science (MSc)

The coastal wetlands in the Georgian Bay area are primarily threatened by human development and the removal of annual water-level fluctuations. From 1999-2013, the water level decreased and remained low. In 2014, the water level rose about 1 m, causing flooding of grass and trees that had grown in the meadow zone during the 14 years when the water level was low. The first goal of this thesis is to explain how and why all wetland plants are relocating during this period. The second goal is to make sure that common indicators of wetland health (water quality, plants, and fish) can still be used during a time when flooding of grasses and trees was occurring in wetlands. The findings in this thesis contribute to the ability to predict and understand how the plants will shift within a wetland during a time of flooding, as well as informing managers on appropriate sampling protocols.

▼ South Africa has a few unique and understudied areas of interest regarding wetlands, of which the Maputaland Coastal Plain (MCP) is one. This is regarded as a large gap in scientific knowledge, especially since firstly, the MCP is regarded as a unique area in terms of biodiversity, geology, social history, and ecosystem variety; and secondly, wetlands are a vulnerable, and yet a greatly important ecosystem type in South Africa. Additionally the wetlands on the aeolian derived sandy soils associated with the MCP are problematic to delineate. Although the wetland delineation guideline of DWAF (2005) gives a list of criteria to aid the delineation process on sandy coastal aquifers, this has never been scientifically reviewed. The aim of this study was to investigate how vegetation and soil properties vary down the topographical slope in various wetland types on the MCP. This was done in order to contribute to the knowledge base and understanding of wetlands in this area, as well as to determine whether differences between zones are significant enough to be used as indicators of wetland boundaries. Soil colour was investigated as a possible new delineation indicator. A section is also devoted to commentary on the current wetland delineation procedure on the MCP. This study shows that wetland types on the MCP are very distinct from each other, and therefore broad statements about the soil and vegetation characteristics of wetlands are discouraged. Three substrate types namely high organic-, duplex-, and sandy substrates dominate wetlands on the MCP. These play a major influential role in the general characteristics and function of the wetland types. Contrary to popular belief, redoximorphic accumulation and -depletions do occur on the MCP, but are often inconsistent in their presence. Chemical soil properties were found not to be good indicators of wetland boundaries on the MCP, although certain patterns can be discerned and applied to determine wetland conditions. The main drivers of wetland vegetation are the wetness- and productivity gradients. A few prominent indicator species can be used for the identification of wetland and non-wetland sites specifically on the MCP. Additionally, a relatively underutilised vegetation assessment procedure called Weighted Averaging was investigated, and can in most cases effectively discern between wetland and non-wetland conditions. This is a useful tool to apply in delineation practices in addition to other indicators. Soil colour can be used to successfully indicate wetland boundaries, and therefore be used as an additional wetland indicator. However, the method requires further testing and refinement for different wetland types. In general the vegetation and soil indicators do not correlate perfectly, and therefore delineation by means of one indicator only is greatly discouraged. An investigation of recommended delineation procedures for the MCP shows that new information on the understanding of wetlands in sandy coastal aquifers urgently needs to be disseminated.

▼ Sea Rockets (Cakile: Brasssicaseae) are plant species specialized for inhabiting coastal fringes and are well known for being successful invaders worldwide. A characteristic patter of invasion in Western North America and New Zealand, has been observed in two species of this genus. Cakile edentula (Bigel.) Hook, native from eastern North America invades and colonizes a coastal area, and is then replaced by Cakile maritima Scop., native from the Atlantic coast of Europe and coast of the Mediterranean Sea. This pattern of invasion and replacement has been repeated in coastal areas of West, South, and East Australian, coast. Currently, few sites in Tasmania are the only places in which these two species coexist. A greater breeding performance of Cakile maritima is one explanation for this replacement pattern In this research, the niche of each species is determined, through ecological niche modelling with MaxEnt, and contrasted to assess the importance of environmental conditions in Cakile edentula's replacement Species' niches were determined through comparison of habitat suitability of each species in the Australian coast. Ecological niche models were developed using data and environmental variables of Cakiles' native range and extrapolated onto Australian records of both species. To compare Cakile edentula's and Cakile maritima's realized niche differences it was necessary to test the ability of each species to predict the distribution of the other. Modelling results showed there are niche differences between both species. However, contrary to what was expected from replacement dynamics, models predicted greater habitat suitability for Cakile edentula than Cakile maritima in the South and East Australian coast. This result, in addition to low model performance and unexpected environmental factors driving C. maritima's distribution, could indicate that model assumptions of equilibrium and unbiased distribution of species records are not being fulfilled. In addition, there are other factors such as the choice of environmental variables, niche similarity methods and biological knowledge of Cakile that may affect niche comparison. Therefore, modelling limitations together with potential solutions are discussed, reinforcing the importance of taking into account the assumptions of species equilibrium and unbiased records, as well as the use of relevant environmental variables.

▼ The role of coastal vegetation in mitigating shoreline erosion by damping of incoming waves and the resultant effect on sediment transport is a critical area of coastal management research. However our understanding of the underlying hydrodynamic processes is limited. Laboratory flume experiments were conducted where a naturally grown emergent vegetation channel and a vegetation-less sand channel were exposed to regular waves. Wave height data was collected using wave gauges located at various points along the channel in the direction of oncoming waves. Acoustic Doppler Velocimeters (ADVs) placed at various depths in the water column measured wave orbital velocity signatures. This thesis investigates the wave-damping phenomenon of the vegetation and attempts to quantify it using the wave attenuation factor. Variation of plant drag coefficient with distance in the vegetation field as well as dependence with Reynolds number, Keulegan Carpenter number and the Viscous Frequency Parameter â are investigated. Horizontal and vertical orbital velocity signals from ADV measurements were analyzed and variation of turbulent kinetic energy with depth has been presented. Comparisons with Linear and Stokes Wave Theory predicted values, calculated using wave height data from wave gauges, were made to understand the turbulence generated by the vegetation bed under wave action. Frequency analysis of the power spectra of wave orbital velocities was used to separate the wave and turbulent portions from the total component of the velocity and has been separately studied to understand the depth variation of the turbulent structures. Wave attenuation factor decreased with increasing distance in the vegetation field while the drag coefficient remained almost constant after a couple of meters. The drag coefficient decreased with both Reynolds number and Keulegan Carpenter number. The observed orbital velocities were less than the wave theory predicted values with the horizontal component showing a zone of decreased attenuation in the mid-depth region, while the vertical velocities showed greater attenuation near the free surface. This work advances the existing knowledge base of vegetative wave attenuation and turbulence studies involving emergent vegetation canopies under regular wave action by employing natural vegetation effects in the laboratory environment as an unique feature of the experiment.

Šiame darbe aptariama šiaurės vakarų Lietuvoje, Plungės rajono savivaldybėje, esančio Babrungo upės baseino reguliuotose upėse vykstantys natūralizacijos procesai. Reguliuotose Babrungo ir Dirnupio upės pakrantės šlaituose ir apsaugos juostose aptikta 871 vienetai sumedėjusios augalijos. Tyrimais nustatyta, kad augalija dažniausiai ir tankiausiai auga šlaito viduriniojoje dalyje. Dirnupio upės tyrinėtame 1,8 km ruože sumedėjusios augalijos plotis kairiajame šlaite Lap = 2,11 ± 0,14 m, dešiniajame šlaite Lap = 1,71 ± 0,23 m. Babrungo upės tyrinėtame 2,2 km ruože apskaičiuotas kairiajame šlaite Lap = 1,86 ± 0,44 m, o dešiniajame šlaite Lap = 1,47 ± 0,27 m. Atlikus dispersinę analizę galima teigti, kad apaugusių sumedėjusia augalija šlaitų pločių vidurkiai, esant 95 % patikimumui, esminiai nesiskiria. Babrungo ir Dirnupio upės ruožų pakrančių apsaugos juostų pločiai miškuose ir pievose atitinka, o ariamoje žemėje neatitinka aplinkosauginių reikalavimų. Ariamose žemėse visi matuoti upės pakrantės apsaugos juostos pločiai buvo ≤5,0 m.

This article is about naturalization processes that take place in the regulated rivers of Babrungas river-basin in the northwestern Lithuania, Plungė district municipality. There are 871 units of woody vegetation in the riverside slopes and protective zones of the regulated Babrungas and Dirnupis rivers. Researchers have shown that usually the vegetation is the densest in the middle part of the slope. The width of woody vegetation on the left slope of 1.8 km strip of the Dirnupis river Lap = 2.11 ± 0.14 m, on the right slope Lap = 1.71 ± 0.23 m. On the left slope of 2.2 km strip of the Babrungas river Lap = 1.86 ± 0.44 m, and on the right slope Lap = 1.47 ± 0.27 m. The dispersive analysis allows to claim that given 95% of reliability, width averages of woody vegetation on the slopes do not differ. The widths of protective coast zones of Babrungas and Dirnupis rivers are the same in the woods and meadows, but in arable land they do not meet the environmental requirements. All widths of protective coast zones of arable land were ≥ 5.0 m.

▼ In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe. To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened. During the design process, the most favourable variant was to construct a dune and beach system in front of the sea dike, which was constructed soon after, and finished in 2015. This changed the 'hard' sea defence to a 'soft' one, linking the beaches and dunes in the north and south with each other. Thereby not only increasing the safety of this part of the coast, but also providing a new area reserved for recreation and nature. The change from a hard to a soft coastal system fundamentally changes the characteristics of the area. Where the old sea dike was a static structure, the newly constructed sandy beach and dune system is very dynamic in nature. The change in properties of this coastal defence stretch brings the question how the HD (Hondsbossche Dunes) can best be maintained to ensure its functions as a sea defence now and in the future. The answer to this question requires insight in the processes relevant to aeolian sediment transport in general, and for the HD in specific. With the knowledge of what processes are important for coastal dune growth in the HD, a model can be selected to make predictions on the likely development of the HD in the future. Aeolian sediment transport, much like hydrodynamic sediment transport, can be described as a balance between forcing and resistance against forcing. The most important factors which govern the dynamics of dune growth as a consequence of aeolian sediment transport are: wind speed and direction, grain size, humidity, sediment availability, beach slope, and vegetation. Especially vegetation (marram grass) is important, as it stabilizes the dunes with its roots and rhizomes below ground, and by locally decreasing the wind velocity with the biomass above ground. The above ground component of the marram grass not only stabilizes the present sediment, it also accommodates a sheltering effect for any incoming sand grains. Dune growth rate is the sum of incoming and outgoing aeolian sediment transport rates. For a healthy dune system, this must be a positive value, as this process negates the effect of dune erosion as a consequence of storm events. In the period between 2015-2018, positive dune growth rates have been observed. An alongshore dune growth velocity gradient has been found, with the highest growth rate being in the south. This is due to a combination of difference in vegetation health (being poorer in the north), and the orientation of the dunes in relation to the average wind direction (more onshore directed in the south). The dune growth rate has decreased over time, but has remained positive over the regarded period. This is due to the eroding beach, which decreases the sediment availability for aeolian transport. Another factor is the… Advisors/Committee Members: Goessen, P.

▼ Abstract Conservation of rare habitats and species are central elements in the management of semi-natural grasslands of high biodiversity. Understanding the impacts of various abiotic and biotic interactions and management methods on threatened species is fundamental to their conservation. In the present study, effects of competition, plant parasitism, grazing and mowing were studied at the community level in Bothnian Bay coastal meadows and in greenhouse. This was the first time when the impacts of various biotic interactions on the critically endangered creeping alkali grass (Puccinellia phryganodes) have been explored in detail in one of its rare occurrences in the boreal vegetation zone in Europe. In addition, questions related to ecological and economical sustainability of cattle grazing on coastal meadows were examined. Puccinellia phryganodes was found to suffer severely from competition with taller graminoids. Simulated and actual grazing by greylag goose, Anser anser, as well as infection by a hemiparasitic plant, Odontites litoralis, were found to indirectly benefit P. phryganodes by decreasing the competitive advantage of its competitors. In spite of the relatively intensive grazing by greylag goose in the field, P. phryganodes experienced a drastic decrease during four years in the grazed experimental quadrats and simultaneously the proportion of the taller graminoids increased substantially. Primary succession of coastal meadow vegetation was found to progress rapidly and continuous formation of suitable open habitats is therefore crucial for the subordinate species. Mowing was found to be an effective management method for some threatened plant species in coastal meadows, but not for P. phryganodes, which would probably benefit more, for example, from livestock grazing. Both lightly and rather intensively managed large open meadows could provide optimal habitats for the critically endangered lesser white fronted goose (Anser erythropus) as well as for the greylag goose. The relatively low and variable yield of the coastal meadow vegetation compared to that of cultivated grasslands sets limits how management by cattle grazing can be implemented. Key factors for both the biodiversity management and livestock production in coastal meadows are timing of the grazing season, intensity of grazing and selection of suitable types of animals.

▼ The main objective and secondary objective, which corresponds to the in-depth research are as follows: (1) To develop guidelines for engineers to include salt marshes in hydraulic infrastructure projects, subject to the Building with Nature philosophy. (2) To investigate the effect of grazing at salt marshes on the coastal protection property. This research concerns the development of guidelines for engineers to include salt marshes in coastal protection projects, subject to the Building with Nature philosophy. The results include important design aspects for engineers and an analysis of trade-offs between biodiversity and the coastal protection property of salt marshes. This research is based on a literature study about the natural and artificial development of salt marsh. Thereafter, the effect of grazing on wave attenuation is modelled by the numerical model SWAN (Simulating WAves Nearshore). The effect of vegetation and the bathymetry is analysed. The vegetation data results from a grazing experiment at the salt marsh at Noord Friesland Buitendijks, in the north of the Netherlands. The results from the literature study and the in-depth research are translated to important design aspects within the engineering design guidelines for salt marsh development. The main conclusion of the in-depth research is that the effect of vegetation on wave attenuation is small compared to the effect of wave breaking and bottom friction. Moreover, the variations in wave attenuation between the different grazing strategies is also small. However, grazing could be used as an ecosystem management strategy, as from literature it follows that grazing positively affects biodiversity. Although the effect of biotic factors on wave energy dissipation is small, the presence of a salt marsh indirectly affects wave attenuation. The salt marsh vegetation enhances sediment accumulation, which leads to a higher bottom profile elevation compared to the bare foreshore. This should be substantiated by future research.

▼ Une série de sondages continentaux (FZ4, FZ5, et SZY) ont été collectés dans la plaine de Fuzhou et dans la montagne de Ningde. Les trois enregistrements ont permis de reconstituer et ainsi de comprendre l'évolution de la végétation ainsi que d'évaluer l'impact de la mousson est-asiatique et les changements du niveau marin sur les environnements du quaternaire récent. Ma thèse donne un aperçu de la végétation passée et des changements paléoclimatiques au cours des 50000 dernières années. Pour les derniers millénaires je me suis aussi intéressé aux activités humaines préhistoriques et leur relation avec les changements de l'environnement local durant l'Holocène. Dans cette thèse, j'ai utilisé une approche multidisciplinaire incluant principalement la palynologie, la sédimentologie, le paléomagnétisme et la micropaléontologie pour reconstituer les environnements passés.L'enregistrement palynologique SZY issu d'une tourbière subalpine couvre les 50000 dernières années en continu. Les diversité de la flore et des changements forestiers au cours des 50 dernières millénaires permettent de reconstituer l'évolution de la mousson régionale dans le sud-est de la Chine. Les changements climatiques estimés par un indice de mousson saisonnier, la température et les précipitations mensuelles ont été quantitativement reconstruits.Les assemblages polliniques pendant la période entre ca. 50 et 30,4 ka cal BP, correspondant au stade isotopique marin (MIS) 3, sont caractérisés par une forte abondance de pollen arboricole, principalement subtropicaux Quercus, Castanopsis/Lithocarpus avec des taxons tempérés de montagne à feuillage caduque tels que Fagus et Alnus et accompagné de quelques conifères mésiques de montagne telles que les Taxodiaceae et Tsuga. Une telle composition de l'écosystème suggère que le MIS 3 était plutôt humide avec une forte mousson d'été. L'insolation d'été élevée peut avoir entraîné une intensification de la mousson au cours de cette période et a donc contribué au maintien d'un tel écosystème subtropical. Une expansion progressive des taxons arborés feuillus, qui a remplacé les taxons subtropicaux à feuillage persistant pendant la période du dernier maximum glaciaire (LGM) (de ca. 30,4 à 11,8 environ cal ka BP), indique que le climat est devenu beaucoup plus frais que lors du MIS 3. Cet intervalle froid se produit entre ca. 21 et 17 cal ka BP lorsque la savane arbustive a augmenté et la forêt de feuillus a diminué rapidement. Cet événement est également marqué par la concentration de pollen qui montre des valeurs faibles au cours du dernier maximum glaciaire. Ceci est probablement lié à un paysage ouvert ou semi-ouvert sous un climat plus sec et plus froid que durant le MIS 3. En comparaison avec les études des isotopes de l'oxygène (δ18O/δ16O) issues de spéléothèmes et ses carottes de glace du Groenland, plusieurs événements climatiques rapides pourraient être reconnues tels que le Dryas récent et l'interstade Bølling-Allerød qui ont marqué la fin de la dernière période glaciaire. Au cours de l'Holocène, la… Advisors/Committee Members: Cheddadi, Rachid (thesis director), Zheng, Zhuo (thesis director).

▼ Storms are considered one of the rapid climatic events that have a dramatic impact on coastal morphology, hence they require further investigation and quantifying of coastal changes and responses. Light detection and ranging (LiDAR) is the most advanced technology to be widely used by researchers for coastal geomorphological studies. The purpose of this study is to apply an object-based approach using repeated LiDAR surveys to understand the short-term morphological changes that occurred on Santa Rosa Island, Florida after category 3 hurricanes Ivan (2004) and Dennis (2005), making it the first study to apply this method, as opposed to previous studies’ commonly used field-based approaches. The first analysis was conducted using a coastal morphology analysis (CMA) tool. In the second analysis, the extracted mean elevation change values were linked to three factors—mean vegetation, mean slope, and mean elevation—to demonstrate their contribution to the change using ordinary least square (OLS) analysis. The third analysis was carried out using the classification and regression tree (CART) analysis. Of the study area, 18.64% encountered erosional processes and 11.35% with depositional processes during Hurricane Ivan, whereas during Hurricane Dennis, 5.91% faced erosional processes and 8.18% was affected by depositional processes. Both hurricanes resulted in a net sediment loss; 283,167 m3 during Hurricane Ivan and 52,440 m3 during Hurricane Dennis. Generally, objects tended to be irregular, asymmetrical, and shaped with smooth boundaries. Along the coast, most objects tended to have an elongated shape, but inland the shapes were more irregular. The overall OLS model during Hurricane Ivan yielded statistically significant results for the three factors, with a confidence level of 0.00 and an adjusted r-square of 0.40; and during Hurricane Dennis, the mean vegetation and mean elevation results yielded significant statistical results (p-value 0.00), while slope did not show significance and had an adjusted r-square of 0.47. CART analysis of both hurricanes ranked the mean elevation as the most important factor in predicting the mean elevation change, followed by the mean slope and finally the mean vegetation variable.

O presente trabalho teve como objetivo avaliar as caracterÃsticas fÃsicas, fÃsico-quÃmicas e quÃmicas e atividade antioxidante total de frutos de viuvinha (Myrcia splendens (Sw.) DC.), mapirunga (Eugenia tinctoria Gagnep.) e araticum-do-brejo (Annona glabra L.) oriundos da vegetaÃÃo litorÃnea do CearÃ, em diferentes estÃdios de maturaÃÃo. Os frutos foram caracterizados fisicamente quanto Ã massa fresca, dimensÃes, coloraÃÃo, rendimento e firmeza. Para a avaliaÃÃo das caracterÃsticas fÃsico-quÃmicas e quÃmicas foram feitas as seguintes anÃlises: sÃlidos solÃveis (SS), acidez total titulÃvel (ATT), pH, relaÃÃo SS/ATT, aÃÃcares solÃveis totais e redutores, pectina solÃvel, vitamina C, clorofila e carotenÃides totais, antocianinas e flavonÃides amarelos, polifenÃis extraÃveis totais (PET) e atividade antioxidante total pelo mÃtodo ABTS. Os resultados indicaram que os frutos de viuvinha e mapirunga apresentaram um aumento na massa fresca, comprimento, diÃmetro e rendimento em polpa no decorrer do amadurecimento. Nos frutos de araticum-do-brejo observou-se um declÃnio nestes parÃmetros no final da maturaÃÃo. Observou-se tambÃm um aumento, no teor de sÃlidos solÃveis totais, na relaÃÃo SS/ATT, aÃÃcares solÃveis totais e aÃÃcares redutores nos frutos analisados Ã medida em que ocorria a hidrÃlise do amido. Apenas nos frutos de viuvinha ocorreu diminuiÃÃo da acidez ao longo do amadurecimento. Houve solubilizaÃÃo da pectina ao longo do amadurecimento, exceto nos frutos de mapirunga. Dentre os compostos bioativos observou-se aumento na vitamina C no decorrer do amadurecimento das frutas analisadas. Constatou-se alto teor de antocianinas nos Ãltimos estÃdios de maturaÃÃo na polpa de mapirunga. Apenas nos frutos de viuvinha houve uma diminuiÃÃo de flavonÃides amarelos no decorrer do amadurecimento. Foram encontrados altos valores de polifÃnois extraÃveis totais e elevada atividade antioxidante nos frutos de viuvinha e mapirunga. Houve correlaÃÃo positiva e significativa entre a atividade antioxidante total e o teor de polifenÃis extraÃveis totais de todas as espÃcies analisadas. As polpas de viuvinha e mapirunga sÃo promissoras tendo em vista considerÃveis teores de compostos bioativos como, carotenÃides, antocianinas, flavonÃides amarelos e polifenÃis totais extraÃveis que as fazem produtos diferenciais no mercado de frutas nativas.

▼ Taiwan is an island surrounded by sea. Due to the topography, the coastal wetlands distribute almost around the west seashore, and some at the estuary of the east seashore. The coastal wetland is a transitional area between territory ecosystem and marine ecosystem. The environment of the coastal wetland is influenced by tide and season, thus the distribution of vegetations here exhibits a dynamic equilibrium. This study attempts to investigate the distribution and composition of the vegetation and the appearance of the habitat environment at the coastal wetland of Taiwan. According to the results, 173 species belonging to 50 families have been recorded. This indicates that the diversity of the marsh vegetation at the coastal wetland is low. Most of the species belong to Gramineae, Compositae and Cyperaceae. Paspalum vaginatum and Phragmites karka are the most dominant plant at coastal marsh environments. According to the results of detrended correspondence analysis (DCA) and cluster analysis (CA), 16 vegetation types including one subtype and one transitional type are classified. The habitats of these vegetation types can be classified into five types, namely tidal fresh water marsh, fresh water-salt marsh, wet meadow, salt marsh and submerged environment. Most of these vegetation types have only one major dominant species. The distribution of the marsh vegetation features a belting pattern, which is mainly limited by the maximum of their salt tolerance from coastal toward inland, or estuary toward headwaters. Subsequently, it can by influenced by soil moisture and pH value. Furthermore, the vegetations are influenced by many additional environmental factors, resulting in a mosaic distribution of vegetation types. The marsh vegetation is processing at an unstable and developing period. Because the coastal wetland is seriously disturbed by human activities, the environmental variation becomes greater. Therefore, the transitional vegetations were observed frequently. Finally, the development pressure due to economic demand is the major cause that makes coastal wetland disappeared. It is urgently needed to protect this sensitive natural resource. Advisors/Committee Members: Yuen-po Yang (committee member), Ho-yih Liu (chair), Chang-sheng Kuoh (chair).

O presente trabalho refere-se a uma análise das alterações ambientais do município de Tramandaí, localizado no Litoral Norte do Estado do Rio Grande do Sul. A pesquisa procura analisar o município em sua totalidade, de forma integrada, a partir das relações natureza e sociedade, tendo como objetivo principal analisar as alterações ambientais geradas por processos de uso e ocupação do solo decorrente do crescimento urbano no município de Tramandaí, com ênfase no período entre 1991 e 2000. Para tanto, foi necessário um levantamento bibliográfico referente ao meio físico e ao processo de urbanização; análise de dados dos Censos demográficos (1960-2000) e setores censitários de Tramandaí (1991-2000) detalhando os bairros Centro e Agual; análise de fotografias áreas de 1974, e imagem de satélite de 2006, do município de Tramandaí, bem como observações de campo e entrevistas. Verificou-se que o município de Tramandaí se enquadra junto aos municípios urbanos com população permanente, e um significativo número de domicílios ocupados o ano inteiro. Foi constatada que mesmo com as emancipações, esse município apresenta incremento populacional decorrente de sua função polarizadora na região. As principais alterações ambientais identificadas no município de Tramandaí foram: retirada de areia das dunas; construção de prédios em substituição as dunas; aterramento de planície inundável e banhado e ocupação urbana desta área; desmatamento; cultivo de eucalipto; entre outras. Após análise dos setores censitários dos bairros Centro e Agual constatou-se que tanto no próprio bairro, como em comparação com o outro existem diferenciações como: no bairro Centro a baixa ocupação demonstra que a maioria dos domicílios é para 2ª residência, a escolaridade média do chefe de domicílio é ensino médio com a média de 10 salários mínimos, quanto a infra estrutura básica neste bairro predomina o abastecimento de água via rede geral, esgotamento sanitário via rede geral e lixo coletado, e na última década os terrenos com moradias unifamiliares estão sendo vendidos para as construtoras de engenharia civil, sendo substituídas por prédios de luxo, mantendo-se a função de 2ª. residência; enquanto que o bairro Agual passou de 2ª residência para uso permanente entre 1991 e 2000 com maior número de moradores em cada domicílio que no bairro Centro, a escolaridade média do chefe de domicílio é ensino fundamental incompleto, e a média de salários, é quase três salários mínimos, em 2000, em parte deste bairro predomina o abastecimento de água via poço e esgotamento sanitário via fossa rudimentar, tendo alguns domicílios com rede geral e fossa séptica; no restante do bairro a metade recebe o abastecimento de água via rede geral, e cresce o n°. de moradias precárias e o n°. de habitantes no bairro Agual. Constatou-se que em Tramandaí ocorre um crescimento diferenciado, tanto em intensidade quanto no perfil da população com necessidades diferenciadas.

The present work refers to an analysis of the environmental alterations of the municipality of Tramandaí,…

▼ This dissertation presents the results of a multi-year interdisciplinary study of a dynamic coastal dune ecosystem restoration effort in Pacific Rim National Park Reserve in British Columbia, Canada. The research is the result of a collaboration with Parks Canada Agency (PCA) who, under the Species at Risk Act (SARA), are mandated to restore habitat for SARA listed species within the dune complex. In response, PCA committed to, and implemented, a dynamic dune ecosystem restoration program that involved widespread removal of invasive vegetation (Ammophila spp.), transplanting of native vegetation, introduction of an endangered species, and volunteer programs to prevent re-growth of Ammophila. A comprehensive monitoring program was developed with PCA and undertaken by the author and PCA collaborators from start of the project in Summer 2008 to Fall of 2012. This dissertation is the product of independent research by the author carried out under the supervision of the advisory committee and does not reproduce written materials prepared for, or by, PCA. The dissertation consists of three separate journal manuscripts (the first two published by completion of the dissertation) that stand alone as independent investigations but are structured here to provide a natural progression of research findings and allow for an overall synthesis of ideas and broader contributions of the research. The dune restoration program afforded an opportunity to review restoration trends and methods and implement a strategy and monitoring protocols based on leading edge science. Accordingly, the first manuscript, Chapter 2, summarises recent trends in coastal dune restoration, discusses relevant research surrounding beach-dune morphodynamics and coastal dune activity, and reviews preliminary data from the project. The study identifies usable control data for the project and builds the criteria for assessing the project as a whole. The second manuscript, Chapter 3, presents and analyses the core data obtained for the dissertation - 5 years of geomorphic monitoring from detailed land surveys with 3 years of analysis of beach-foredune-transgressive dune sediment budget responses derived from aerial LiDAR surveys. This chapter identifies several trends in the dune systems’ response to restoration that, with reference to the indicators developed in Chapter 2, suggest improved levels of dynamism in the landscape. Finally, Chapter 4 (manuscript 3), extends the findings of the restoration study and utilises the rich data set obtained from the restoration program to develop a dynamic mapping technique that better conveys the spatial-temporal morphodynamic behaviour of dune ecosystems. The study comments broadly on the potential to apply these data and techniques to the study of disturbance events in beach-dune systems. The dissertation is concluded (Chapter 5) with an overall summary of key research objectives and contributions, and presents recommendations for future research.

▼ Large aquaculture systems may have the potential to damp wave energy for coastal protection. The performance of these systems are influenced by the dynamics of components such as flexible kelp blades and mussel droppers. In this thesis, the dynamics of kelp blades and mussel droppers were investigated with a consistent-mass cable model with focus on understanding the asymmetric motion of kelp blades. The results showed the asymmetric blade motion in symmetric waves is caused by the spatial asymmetry of the encountered wave orbital velocities due to blade displacements and the asymmetric action on the blade by vertical wave orbital velocities. For the kelp grown from the bottom, the asymmetry of blade motion provides ‘shelter’ that could inhibit sediment suspension and coastal erosion. For suspended kelp attached to a longline, the asymmetric motion would induce the kelp to roll over the attachment in large wave conditions. With understanding the blade dynamics, physical model experiments using the morphological and mechanical properties of the cultivated Saccharina latissima at Saco Bay, Maine in the USA were conducted to investigate the wave attenuation characteristics of suspended kelp farms. The results indicated that 20 longlines with 100 plants/m could reduce up to 23% energy of 6.3 s waves. To predict wave attenuation under wider conditions, numerical and analytical wave attenuation models coupled with blade motion were developed for regular and irregular waves. With the analytical model, a case study at a site in Northeastern US showed the potential of suspended aquaculture farms to dissipate wave energy in a storm event. Compared to naturally occurring submerged aquatic vegetation (SAV), suspended aquaculture farms were found to perform better at attenuating shorter waves and less impacted by water level changes due to tides, surge and sea level rise. Implementing offshore aquaculture structures in conjunction with SAV-based living shorelines that can enhance the coastal defense of SAV-based living shorelines. This research is useful for the design of suspended aquaculture structures for nature-based coastal protection. The analytical wave attenuation models are also convenient to implement in large-scale models to analyze the influences of wave attenuation on coastal morphology.

▼ Increasing sea levels and anthropogenic disturbances have caused the world’s coastal vegetation to decline 25-50% in the past 50 years. Future sea level rise (SLR) rates are expected to increase, further threatening coastal habitats. In combination with SLR, the Everglades ecosystem has undergone large-scale drainage and restoration changing Florida’s coastal vegetation. Everglades National Park (ENP) has 21 coastal plant species threatened by SLR. My dissertation focuses on three aspects of coastal plant community change related to SLR and dehydration. 1) I assessed the extent and direction coastal communities—three harboring rare plant species—shifted from 1978 to 2011. I created a classified vegetation map and compared it to a 1978 map. I hypothesized coastal communities transitioned from less salt- and inundation-tolerant to more salt- and inundation-tolerant communities. I found communities shifted as hypothesized, suggesting the site became saltier and wetter. Additionally, all three communities harboring rare plants shrunk in size. 2) I evaluated invading halophyte (salt-tolerant) plant influence on soil salinity via a replacement series greenhouse experiment. I used two halophytes and two glycophytes (non-salt-tolerant) to look at soil salinity over time under 26 and 38‰ groundwater. I hypothesized that halophytes increase soil salinity as compared to glycophytes through continued transpiration during dry, highly saline periods. My results supported halophytic influence on soil salinity; however, not from higher transpiration rates. Osmotic or ionic stress likely decreased glycophytic biomass resulting in less overall plant transpiration. 3) I assessed the best plant life-stage to use for on-the-ground plot-based community change monitoring. I tested the effects of increasing salinity (0, 5, 15, 30, and 45‰) on seed germination and seedling establishment of five coastal species, and compared my results to salinity effects on one-year olds and adults of the same species. I hypothesized that seedling establishment was the most vulnerable life-stage to salt stress. The results supported my hypothesis; seedling establishment is the life-stage best monitored for community change. Additionally, I determined the federally endangered plant Chromolaena frustrata’s salinity tolerance. The species was sensitive to salinity >5‰ at all developmental stages suggesting C. frustrata is highly threatened by SLR. Advisors/Committee Members: Jennifer H.

▼ Marsh vegetation is widely considered to offer protection against coastal storm damage, and vegetated flow has thus become a key area of hydrodynamic research. This study investigates the utility of simulated Spartina alterniora marsh vegetation as storm protection using an ADV measurement technique, and is the first to apply jet self-similarity analysis to characterize the overall mean and turbulent flow properties of a three-dimensional axisymmetric jet through a vegetated array. The mean axial flow of a horizontal axisymmetric turbulent jet is obstructed by three configurations of staggered arrays of vertical rigid plant stems. The entire experiment is repeated over five sufficiently high jet Reynolds number conditions to ensure normalization and subsequent collapse of data by nozzle velocity so that experimental error is obtained. All self-similarity parameters for the unobstructed free jet correspond to typical published values: the axial decay coefficient B is 5:8 +/- 0:2, the Gaussian spreading coefficient c is 85 +/- 5, and the halfwidth spreading rate eta_(1/2) is 0:093 +/- 0:003. Upon the introduction of vegetation, from partially obstructed to fully obstructed, B falls from 5:1+/- 0:2 to 4:2 +/- 0:2 and finally 3:7 +/-0:1 for the fully obstructed case, indicating that vegetation reduces axial jet velocity. Cross-sectionally averaged momentum for the unobstructed free jet is M=M0 = 1:05 +/- 0:07, confirming conservation of momentum. Failure of conservation of momentum is most pronounced in the fully obstructed scenario – M=M0 = 0:54 +/- 0:05. The introduction of vegetation increases spreading of the impinging jet. The entrainment coefficient alpha for the free jet case is 0.0575; in the fully obstructed case, alpha = 0:0631. Mean advection of mean and turbulent kinetic energy demonstrates an expected reduction in turbulence intensity within the vegetated array. In general, turbulent production decreases as axial depth of vegetation increases, though retains the bimodal profile of the free jet case; the fully vegetated case, however, exhibits clear peaks behind plant stems. Turbulent transport was shown to be unaffected by vegetation and appears to be primarily a function of axial distance from the jet nozzle. An analysis of rate of dissipation revealed that not only does the cumulative effect of upstream wakes overall depress the magnitude of spectral energy density across all wavenumbers but also that plant stems dissipate large anisotropic eddies in centerline streamwise jet flow. This study, thus, indicates that sparse emergent vegetation both reduces axial flow velocity and has a dissipative effect on jet flow. Typically, however, storm surge does not exhibit the lateral spreading demonstrated by an axisymmetric jet; therefore, the results of this study cannot conclusively support the claim that coastal vegetation reduces storm surge axial velocity.
