Download or read book River Networks as Ecological Corridors written by Andrea Rinaldo and published by Cambridge University Press. This book was released on 2020-10-22 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: River networks are critically important ecosystems. This interdisciplinary book provides an integrated ecohydrological framework blending laboratory, field, and theoretical evidence that changes our understanding of river networks as ecological corridors. It describes how the physical structure of the river environment impacts biodiversity, species invasions, population dynamics, and the spread of waterborne disease. State-of-the-art research on the ecological roles of the structure of river networks is summarized, including important studies on the spread and control of waterborne diseases, biodiversity loss due to water resource management, and invasions by non-native species. Practical implications of this research are illustrated with numerous examples throughout. This is an invaluable go-to reference for graduate students and researchers interested in river ecology and hydrology, and the links between the two. Describing new related research on spatially-explicit modeling of the spread of waterborne disease, this book will also be of great interest to epidemiologists and public health managers.

Download or read book Life History Distribution and Invertebrate Host parasite Interactions of the Causative Agent of Proliferative Kidney Disease PKD Tetracapsuloides Bryosalmonae written by Inês Fontes and published by . This book was released on 2015 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proliferative kidney disease (PKD) is an emerging disease of salmonid fish that is linked with environmental change. The causative agent is the myxozoan Tetracapsuloides bryosalmonae (Tb) which exploits the freshwater bryozoan Fredericella sultana (Fs) as definitive hosts. Fs forms colonies that reproduce mainly asexually through fragmentation and the production of over-wintering dormant stages (statoblasts). In Fs the parasite cycles between overt and covert infections, the former characterised by sacs containing spores infectious to fish. This thesis aims to increase understanding of the prevalence, severity and transmission of Tb in Fs through field and laboratory studies and to identify factors associated with the presence and abundance of the parasite and its hosts in British rivers. The results of this research are ultimately relevant for the conservation, health and diversity of wild fish populations. I provide an introduction to Tb and PKD and follow with four data chapters on infection dynamics of Tb within bryozoan hosts and its detection in river water. A fifth data chapter investigates factors affecting the distribution and abundance of Fs and Tb and the identification of disease risks. A concluding chapter summarises the salient points of my research and suggests directions for future work. My research has demonstrated: high prevalence of covert infections in bryozoan populations in space and time (Chapter 2); transmission to colony fragments and statoblasts via cryptic stages (Chapter 3); the quantification of Tb in water samples in early summer and a greater detection of Tb in larger sample volumes (Chapter 4); that host stress promotes horizontal transmission from bryozoans to fish (Chapter 5); that Fs is more likely to occur in warm, eutrophic habitats in the south of Britain (Chapter 6).

Download or read book Quagga and Zebra Mussels written by Thomas F. Nalepa and published by CRC Press. This book was released on 2013-10-25 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.

This book was released on 2020-03-26 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our world is becoming more urban. More than fifty percent of the global population now lives in cities, which poses new challenges for sustainable development. This book integrates theory and methods of sustainability assessment with concepts from systems science to provide guidelines for assessing the sustainability of urban systems. It discusses different aspects of urban sustainability, from energy and housing, to mobility and health, covering social, economic and environmental factors, as well as the various stakeholders and actors involved. The book argues for the need to find models and solutions in order to design sustainable cities of the future in light of the complexity of urban social life. Including diverse case studies from the developed and developing world, this book provides a useful reference for researchers and students from a broad range of disciplines working in the field of sustainability, as well as for environmental consultants and policy makers.
Download or read book Climate Change Ocean Acidification and Sponges written by José Luis Carballo and published by Springer. This book was released on 2017-10-27 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.

Download or read book Hydrological and Biological Responses to Forest Practices written by John D. Stednick and published by Springer Science & Business Media. This book was released on 2007-12-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

Download or read book Climate Change Impacts on Freshwater Ecosystems written by Martin Kernan and published by John Wiley & Sons. This book was released on 2011-02-14 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
Download or read book Demographic Methods Across the Tree of Life written by Roberto Salguero-Gomez and published by Oxford University Press. This book was released on 2021 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demography is everywhere in our lives: from birth to death. Indeed, the universal currencies of survival, development, reproduction, and recruitment shape the performance of all species, from microbes to humans. The number of techniques for demographic data acquisition and analyses across the entire tree of life (microbes, fungi, plants, and animals) has drastically increased in recent decades. These developments have been partially facilitated by the advent of technologies such as GIS and drones, as well as analytical methods including Bayesian statistics and high-throughput molecular analyses. However, despite the universality of demography and the significant research potential that could emerge from unifying: (i) questions across taxa, (ii) data collection protocols, and (iii) analytical tools, demographic methods to date have remained taxonomically siloed and methodologically disintegrated. This is the first book to attempt a truly unified approach to demography and population ecology in order to address a wide range of questions in ecology, evolution, and conservation biology across the entire spectrum of life. This novel book provides the reader with the fundamentals of data collection, model construction, analyses, and interpretation across a wide repertoire of demographic techniques and protocols. It introduces the novice demographer to a broad range of demographic methods, including abundance-based models, life tables, matrix population models, integral projection models, integrated population models, individual based models, and more. Through the careful integration of data collection methods, analytical approaches, and applications, clearly guided throughout with fully reproducible R scripts, the book provides an up-to-date and authoritative overview of the most popular and effective demographic tools. Demographic Methods across the Tree of Life is aimed at graduate students and professional researchers in the fields of demography, ecology, animal behaviour, genetics, evolutionary biology, mathematical biology, and wildlife management.
