The Biology of Aquatic and Wetland Plants

The Biology of Aquatic and Wetland Plants

Aquatic plants play a critically important role in maintaining ecosystem health. They are natural biological filters in freshwater and estuarine wetlands; they contribute to the reproductive success of many organisms some of which are harvested for food; they assist in flood control; and they are prominent elements in the aesthetics and recreational use of freshwater and estuarine habitats. Despite this globally recognized importance wetlands have faced and continue to face threats from the encroachment of human activities. The Biology of Aquatic and Wetland Plants is a thorough and up-to-date textbook devoted to these plants and their interactions with the environment. The focus is on botanical diversity from the perspective of evolutionary relationships emphasizing the role of evolution in shaping adaptations to the aquatic environment. By incorporating recent findings on the phylogeny of green plants with special emphasis on the angiosperms the text is broadly useful for courses in plant biology physiology and ecology. Additionally a chapter on population biology and evolutionary ecology complements the evolutionary backdrop of hydrophyte biology by examining the details of speciation and applications of modern genetic approaches to aquatic plant conservation. Key Features • Synthesizes recent and seminal literature on aquatic and wetland plants • Emphasizes evolutionary history as a factor influencing adaptations to the wetland environment • Provides a global perspective on plant diversity and threats facing wetland ecosystems • Highlights research needs in the field of aquatic and wetland plant biology • Includes 280 figures with more than 300 color photographs and 41 tables to provide ease of access to important concepts and information

PKI Implementation and Infrastructures

PKI Implementation and Infrastructures

The concept of a PKI (public key infrastructure) has been around for decades but it is one strand of IT which has taken an extraordinarily long time to come to fruition within the mainstream. This is mostly because implementing a PKI is time consuming and difficult. Maintaining a PKI is equally time consuming and even more difficult within the real world of mergers and acquisitions against a backdrop of ever-changing technology. Many organisations simply give up and hand everything over to a third party who promises to manage everything on their behalf. This is generally not a good idea and simply delays the inevitability of failures and misunderstood complexity. This book explores all the aspects of implementing and maintaining a PKI that the other books on the subject seem to miss. It reflects decades of hard-won experience not only in PKI not only in IT not only in electronics but in business government agencies and academia alike. The book also explores the existence of a PKI alongside other technologies such as biometrics and against an ever-changing world of development methodologies. This last point is particularly relevant at this time as we are in the middle of a quiet but all encompassing revolution in this respect. Consequently this is the one book on PKI that you have to have on your shelf whether you be a company director IT manager government minister or teacher of IT. It is the book which fills in all the gaps left in the literature and treads paths which others fear to tread. You will enjoy it enormously if you are from an IT background. | PKI Implementation and Infrastructures

Critical Infrastructure Homeland Security and Emergency Preparedness

Critical Infrastructure Homeland Security and Emergency Preparedness

Critical Infrastructure: Homeland Security and Emergency Preparedness Fifth Edition represents a continuation of research and recommendations from the past editions that spans nearly twenty years of focusing on critical infrastructure (CI) protection. Over that time the operating threat and technical environments have changed drastically. The doctrines that have guided practitioners across various domains have also evolved due to changing demands. This is a natural result when doctrines collide and gradually evolve toward and coalesce into a singular understanding of an issue. Those who have practiced in this domain have seen these collisions in the past - an example being the convergence of physical security and cyber information and operational) technologies security. It is with this backdrop and understanding of the domain that the authors not only describe the current state of affairs but also provide a means through which researchers and participants - such as practitioners students industry stakeholders owners and operators in various government and private CI sectors - can look at trends and changes the in the domain that may not be apparent elsewhere. The authors identify shifts in today’s environment that move the thinking away from simply the robustness of systems to their adaptability and resilience. They outline design processes that likewise are evolving away from the simple adoption of best practices to risk-based management and even towards structures based on engineering-driven principles. These changes are not occurring at a unified pace and the differences can result in tensions between certain communities. However the debate itself is indicative of the critical thinking that is beginning to take hold within each infrastructure domain. Critical Infrastructure Fifth Edition continues to critically examine the evolving importance of our critical infrastructure to our society - recognizing the underpinning value of cyber technology and how physical infrastructures and delivery models impact and affect people and society. | Critical Infrastructure Homeland Security and Emergency Preparedness

Relevant Acoustic Phonetics of L2 English Focus on Intelligibility

Relevant Acoustic Phonetics of L2 English Focus on Intelligibility

Intelligibility is the ultimate goal of human communication. However measuring it objectively remained elusive until the 1940s when physicist Harvey Fletcher pioneered a psychoacoustic methodology for doing so. Another physicist von Bekesy demonstrated clinically that Fletcher’s theory of Critical Bands was anchored in anatomical and auditory reality. Fletcher’s and Bekesy’s approach to intelligibility has revolutionized contemporary understanding of the processes involved in encoding and decoding speech signals. Their insights are applied in this book to account for the intelligibility of the pronunciation of 67 non-native speakers from the following language backgrounds –10 Arabic 10 Japanese 10 Korean 10 Mandarin 11 Serbian and Croatian the Slavic Group 6 Somali and 10 Spanish speakers who read the Speech Accent Archive elicitation paragraph. Their pronunciation is analyzed instrumentally and compared and contrasted with that of 10 native speakers of General American English (GAE) who read the same paragraph. The data-driven intelligibility analyses proposed in this book help answer the following questions: Can L2 speakers of English whose native language lacks a segment/segments or a suprasegment/ suprasegments manage to produce it/them intelligibly? If they cannot what segments or suprasegments do they use to substitute for it/them? Do the compensatory strategies used interfere with intelligibility? The findings reported in this book are based on nearly 12 000 measured speech tokens produced by all the participants. This includes some 2 000 vowels more than 500 stop consonants over 3 000 fricatives nearly 1 200 nasals about 1 500 approximants a over 1 200 syllables onsets as many as 800 syllable codas more than 1 600 measurement of F0/pitch and duration measurements of no fewer than 539 disyllabic words. These measurements are in keeping with Baken and Orlikoff (2000:3) and in accordance with widely accepted Just Noticeable Difference thresholds and relative functional load calculations provided by Catforda (1987). | Relevant Acoustic Phonetics of L2 English Focus on Intelligibility

Quaternary Vegetation Dynamics The African Pollen Database

Quaternary Vegetation Dynamics The African Pollen Database

This book celebrates the relaunch of the African Pollen Database presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e. g. abundance of forests vs. grasslands) provide insights into changes in biodiversity and gain empirical evidence of vegetation response to climatic change and human activity. In this the 35th Volume of Palaeoecology of Africa we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution human activity climate change and vegetation dynamics during the Quaternary the last 2. 6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles) human evolution and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states identify the drivers of vegetation change and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i. e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past) and (ii) the past is the key to the future (i. e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western eastern central and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change) as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future. | Quaternary Vegetation Dynamics The African Pollen Database
