Book Synopsis The Structure and Function of Peatlands in the Hudson Bay Lowland by : Lorna Harris
Download or read book The Structure and Function of Peatlands in the Hudson Bay Lowland written by Lorna Harris and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The peatlands of the Hudson Bay Lowland (HBL) are the world's second largest expanse of northern peatland and are globally important carbon (C) stores. Within the bogs and fens covering this extensive landscape, small-scale variations in surface elevation (microtopography - hummocks and hollows) form distinct spatial patterns accentuated by different vegetation cover related to water table depth. These spatial differences in peatland structure and biogeochemical function enable peatlands to occupy alternate dry and wet stable states, therefore increasing peatland resilience to environmental change. The objectives of this research were to examine mechanisms controlling peatland structure and function through analysis of field evidence from HBL peatlands. Relationships among vegetation, hydrology, and nutrients were examined for peatland microforms to test current hypotheses and conditions of peatland development models, and whether these models are applicable to HBL peatlands. My analysis shows the development of surface patterns of microforms within the HBL peatlands may be explained by small-scale structuring mechanisms that control peat accumulation at the microform scale, specifically, the peat accumulation and water ponding mechanisms. Vegetation type is an important control, with greater shrub cover on hummocks associated with larger production for hummocks than hollows. My results also suggest the occurrence of different spatial patterns depends on position within a peat landform, with these differences attributed to varying ecohydrological settings related to landscape-scale hydrology. In turn, the ecohydrological setting influences the strength and direction of feedback mechanisms controlling peat accumulation at the microform scale. Mat-forming lichens cover a large area of the surface of HBL peatlands (up to 50 % in places) and are an important control for peat accumulation and microform development. My results demonstrate that where there are thick lichen mats, local peat accumulation ceases through smaller productivity, faster lichen decay rates, and a loss of structural integrity in underlying peat. Lichens therefore represent a significant temporary limit to peat growth, likely constraining or reducing hummock height relative to adjacent hollows.The potential effects of hydrological change (drier conditions and lower water tables caused by gradual short-term drainage) on these relationships, and on peatland structure and function, were also assessed. My results reveal changes in vegetation and biogeochemical processes are dependent on microform. A significant loss of vegetation and associated biogeochemical changes in dry pools indicate a shift in ecosystem state. Minor changes for hummocks and intermediate microforms however, demonstrate the resilience of HBL peatlands to hydrological change that may be analogous to future climate change scenarios. This thesis contributes new knowledge on the current state of bogs and fens in the HBL for which there has been limited research, and provides insight into possible mechanisms controlling peatland structure and function. This understanding will be invaluable when considering the risks of climate change and increasing development for infrastructure and mining in these iconic peatlands. " --
Book Synopsis Examining Large-scale Peatland Patterns in the Hudson Bay Lowland by : Qianru Wang
Download or read book Examining Large-scale Peatland Patterns in the Hudson Bay Lowland written by Qianru Wang and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Peatland ecosystems are important for maintaining biodiversity, balancing the hydrological system, and regulating climate variability. The development of peatlands strongly affects the global carbon cycling, which in turn contributes to changes in both large-scale structure and community compositions. It has been proposed that peatlands can be viewed as complex adaptive systems with varying degrees of self-regulation due to a series of negative feedbacks on peatland hydrology, vegetation, nutrients, and peat accumulation. This study utilizes several classification algorithms to classify and examine the peatland patterns over a regional scale of the landscape in the Hudson Bay Lowland. Four typical types of peatlands are detected though some errors and uncertainties remain. Moreover, pattern regulations are examined and quantified by several spatial analysis methods such as image pixel area calculation, density-based spatial clustering of applications with noise, autocorrelation analysis (including river buffer test), co-location analysis, and watershed extraction (with slope calculations). The quantification results show a significant correlation between different types of peatlands and confirm that hydrological features drive regular patterns. Furthermore, this thesis opens the door for the extended modelling of large-scale two-dimensional peatland accumulation surface patterns which could help demonstrate the self-regulated properties of large-scale peatlands and explain associations between peatland horizontal successions and different environmental factors"--

Book Synopsis Land Use and Land Cover Mapping in Europe by : Ioannis Manakos
Download or read book Land Use and Land Cover Mapping in Europe written by Ioannis Manakos and published by Springer. This book was released on 2014-07-08 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land use and land cover (LULC) as well as its changes (LUCC) are an interplay between bio-geophysical characteristics of the landscape and climate as well as the complex human interaction including its different patterns of utilization superimposed on the natural vegetation. LULC is a core information layer for a variety of scientific and administrative tasks(e.g. hydrological modelling, climate models, land use planning).In particular in the context of climate change with its impacts on socio-economic, socio-ecologic systems as well as ecosystem services precise information on LULC and LUCC are mandatory baseline datasets required over large areas. Remote sensing can provide such information on different levels of detail and in a homogeneous and reliable way. Hence, LULC mapping can be regarded as a prototype for integrated approaches based on spaceborne and airborne remote sensing techniques combined with field observations. The book provides for the first time a comprehensive view of various LULC activities focusing on European initiatives, such as the LUCAS surveys, the CORINE land covers, the ESA/EU GMES program and its resulting Fast-Track- and Downstream Services, the EU JRC Global Land Cover, the ESA GlobCover project as well as the ESA initiative on Essential Climate Variables. All have and are producing highly appreciated land cover products. The book will cover the operational approaches, but also review current state-of-the-art scientific methodologies and recommendations for this field. It opens the view with best-practice examples that lead to a view that exceeds pure mapping, but to investigate into drivers and causes as well as future projections.

Book Synopsis Wetlands and Human Health by : C Max Finlayson
Download or read book Wetlands and Human Health written by C Max Finlayson and published by Springer. This book was released on 2015-08-03 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses the interactions between wetlands and human health and well-being. A key feature is the linking of ecology-health and the targeting of practitioners and researchers. The environmental health problems of the 21st Century cannot be addressed by the traditional tools of ecologists or epidemiologists working in their respective disciplinary silos; this is clear from the emergence and re-emergence of public health and human well-being problems such as cholera pandemics, mosquito borne disease, and episodic events and disasters (e.g. hurricanes). To tackle these problems requires genuine cross-disciplinary collaboration; a key finding of the recently concluded Millennium Ecosystem Assessment when looking at human well-being and ecosystem health. This book brings the disciplines of ecology and health sciences closer to such a synthesis for researchers, teachers and policy makers interested in or needing information to manage wetlands and human health and well-being issues.
