Available in PDF, EPUB and Kindle. Book excerpt: Previous field work characterized the wetness requirements of four plant communities by modeling their hydrologic regimes in three reference wetlands and correlating the results. The objectives of this work were to: 1) determine whether the modeled predictions were accurate by growing four tree species that represented different plant communities under the modeled hydrologies in the greenhouse, and 2) determine how different tree species adapt to saturated soil conditions. Bald cypress (Taxodium distichum), sweet bay (Magnolia virginiana), pond pine (Pinus serotina), and swamp chestnut oak (Quercus michauxii) were grown in greenhouse experiments under three hydrologic regimes: i) ponded for 100 d, ii) ponded for 15 d, and iii) unsaturated. Loamy sand and sapric materials from a restored Carolina Bay were the substrate materials used to represent mineral and organic soils. Bald cypress (representing Non-riverine Swamp Forest) adapted well to 100 d of ponding by producing lateral roots near the surface, aerenchyma tissue in roots and stem, and increasing P uptake. In organic soils ponded for 100 d, bald cypress had significantly greater height, diameter, and total biomass than all other tree species. Sweet bay (representing Bay Forest) adapted well to 100 d of ponding by producing adventitious roots on the submerged portion of the stem. Pond pine (representing Pond Pine Woodland) was intolerant to 100 d of ponded conditions and 75% of the seedlings died in the ponded experiments. Swamp chestnut oak (representing Non-riverine Wet Hardwood Forest) was intolerant to ponding and all seedlings died in ponded treatments. A rhizotron study was conducted to further observe and quantify biological, morphological, and physiological changes in two wetland tree species with differing tolerances to saturated conditions. Bald cypress and swamp chestnut oak seedlings were grown under ponded and unponded conditions for 106 d in rhizotrons containing the same soils used in the contain.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Located at the interface between uplands and surface water networks, headwater wetlands act as a natural filter to improve downstream water quality and play a critical role in maintaining the ecological integrity of downstream aquatic ecosystems. Vulnerable to development pressure, as well as indirect impacts from land use and climate change, the loss and alteration of headwater wetlands has been linked to the loss of biodiversity and regional water quality declines worldwide. The overall goal of this dissertation is to address some of the challenges associated with the management and conservation of headwater wetlands in the coastal plain of Virginia including: the identification of palustrine forested wetlands in flat coastal landscapes (Chapter II); and improved understanding of the impacts of land use (Chapter III) and climate change (Chapter IV) on the hydrologic regime of headwater wetlands. First, a simple model of wetland distribution was developed by characterizing the depth to groundwater using widely available geospatial data, including surface water features and a high-resolution digital elevation model. Comparison with the National Wetland Inventory (NWI) and targeted field validation indicated that this model provides an effective approach to identify palustrine forested wetlands often unmapped by NWI. Results from this study indicate that there may be at least 37% more wetland area than is currently mapped within the study area; and that in the future, modeling approaches should be used in addition to NWI mapping to better understand the full extent and distribution of wetlands in forested areas. The impacts of land use and climate change were then investigated through field studies of headwater wetland hydrology and community composition. Potential differences in headwater wetland hydrology were evaluated through an index of hydrophytic vegetation occurrence, the wetland prevalence index (PI). Changes in PI between sapling and canopy strata, with respect to local land use, indicated that decreased forest cover was associated with a shift in plant community composition, and that increasing road density was associated with a shift towards more upland type species, while increasing agricultural cover was associated with a shift towards more wetland type species. The effects of climate change, including rising temperatures and altered precipitation patterns were evaluated by developing an empirical model of water table depth for coastal headwater wetlands. Wetland water levels were simulated under current and potential future conditions to evaluate the impact of climate change on the hydrologic regime of headwater wetlands. Based on the model scenarios applied in this study, it appears that decreasing water availability may lead to drier conditions at headwater wetlands by the end of the 21st century, with a substantial decline in minimum water levels and a 3-10% decline in average annual percent saturation. Collectively, the results of this dissertation provide practical insights for improving the conservation and management of coastal headwater wetlands. Improved understanding of the extent and distribution of previously unmapped forested wetlands can improve the capacity to monitor wetland loss and degradation. Additionally, clarifying the influence of land use and climate on the hydrologic regime of these wetlands, can help improve the capacity to forecast and then mitigate potential future impacts to wetland hydrology.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the papers presented at the Smart and Sustainable Built Environments Conference, 2018 (SASBE).This latest research falls into two tracks: smart and sustainable design and planning cities; and the technicalities of smart and sustainable buildings. The growth of smart cities is evident, but not always linked to sustainability. This book gives an overview of the latest academic developments in increasing the smartness and sustainability of our cities and buildings. Aspects such as inclusivity, smart cities, place and space, the resilient city, urbanity and urban ecology are prominently featured in the design and planning part of the book; while energy, educational buildings, comfort, building design, construction and performance form the sub-themes of the technical part of the book. This book will appeal to urban designers, architects, urban planners, smart city designers and sustainable building experts.

Download or read book XXXXX written by Xxxxx and published by xxxxx. This book was released on 2006 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: xxxxx proposes a radical, new space for artistic exploration, with essential contributions from a diverse range of artists, theorists, and scientists. Combining intense background material, code listings, screenshots, new translation, [the] xxxxx [reader] functions as both guide and manifesto for a thought movement which is radically opposed to entropic contemporary economies. xxxxx traces a clear line across eccentric and wide ranging texts under the rubric of life coding which can well be contrasted with the death drive of cynical economy with roots in rationalism and enlightenment thought. Such philosophy, world as machine, informs its own deadly flipside embedded within language and technology. xxxxx totally unpicks this hiroshimic engraving, offering an dandyish alternative by way of deep examination of software and substance. Life coding is primarily active, subsuming deprecated psychogeography in favour of acute wonderland technology, wary of any assumed transparency. Texts such as Endonomadology, a text from celebrated biochemist and chaos theory pioneer Otto E. Roessler, who features heavily throughout this intense volume, make plain the sadistic nature and active legacy of rationalist thought. At the same time, through the science of endophysics, a physics from the inside elaborated here, a delicate theory of the world as interface is proposed. xxxxx is very much concerned with the joyful elaboration of a new real; software-led propositions which are active and constructive in eviscerating contemporary economic culture. xxxxx embeds Perl Routines to Manipulate London, by way of software artist and Mongrel Graham Harwood, a Universal Dovetailer in the Lisp language from AI researcher Bruno Marchal rewriting the universe as code, and self explanatory Pornographic Coding from plagiarist and author Stewart Home and code art guru Florian Cramer. Software is treated as magical, electromystical, contrasting with the tedious GUI desktop applications and user-led drudgery expressed within a vast ghost-authored literature which merely serves to rehearse again and again the demands of industry and economy. Key texts, which well explain the magic and sheer art of programming for the absolute beginner are published here. Software subjugation is made plain within the very title of media theorist Friedrich Kittler's essay Protected Mode, published in this volume. Media, technology and destruction are further elaborated across this work in texts such as War.pl, Media and Drugs in Pynchon's Second World War, again from Kittler, and Simon Ford's elegant take on J.G Ballard's crashed cars exhibition of 1970, A Psychopathic Hymn. Software and its expansion stand in obvious relation to language. Attacking transparency means examining the prison cell or virus of language; life coding as William Burrough's cutup. And perhaps the most substantial and thorough-going examination is put forward by daring Vienna actionist Oswald Wiener in his Notes on the Concept of the Bio-adapter which has been thankfully unearthed here. Equally, Olga Goriunova's extensive examination of a new Russian literary trend, the online male literature of udaff.com provides both a reexamination of culture and language, and an example of the diversity of xxxxx; a diversity well reflected in background texts ranging across subjects such as Leibniz' monadology, the ur-crash of supreme flaneur Thomas de Quincey and several rewritings of the forensic model of Jack the Ripper thanks to Stewart Home and Martin Howse. xxxxx liberates software from the machinic, and questions the transparency of language, proposing a new world view, a sheer electromysticism which is well explained with reference to the works of Thomas Pynchon in Friedrich Kittler's essay, translated for the first time into English, which closes xxxxx. Further contributors include Hal Abelson, Leif Elggren, Jonathan Kemp, Aymeric Mansoux, and socialfiction.org.

This book was released on 2000-08-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.
