Download or read book Biodiversity Conservation and Phylogenetic Systematics written by Roseli Pellens and published by Springer. This book was released on 2016-02-24 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.
Download or read book Whale watching written by James Higham and published by Cambridge University Press. This book was released on 2014-03-27 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within little more than a generation, whale-watching has been subject to global industrial development. It has been portrayed by destinations and business operators, and advocated by environmental groups, as a sustainable activity and an alternative to whaling. However, in recent years the sustainability of these activities has increasingly been questioned, as research shows that repeated disturbance by boat traffic can severely disrupt critical behaviours of cetaceans in the wild. Bringing together contributions by international experts, this volume addresses complex issues associated with commercial whale-watching, sustainable development and conservation of the global marine environment. It highlights widely expressed concerns for the failure of policy, planning and management and pinpoints both long-standing and emerging barriers to sustainable practice. Featuring numerous case studies, the book provides critical insights into the diverse socio-cultural, political, economic and ecological contexts of this global industry, highlighting the challenges and opportunities that arise along the pathways to sustainability.
Download or read book Strategic Plan for Conducting Large Geographic Scale Ship Based Surveys to Support the U S Marine Mammal Protection and Endangered Species Acts written by Ballance, Lisa T. and published by Government Printing Office. This book was released on 2017 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motivation for this strategic plan is to provide a national, unified approach for meeting science needs in partial support of the U.S. Marine Mammal Protection Act (MMPA) and the Endangered Species Act (ESA). The specific objective is to provide a framework for discussion of ship time with respect to, chiefly, cetacean science needs. The plan presented here is meant to aid in strategic planning for these science requirements in the context of other National Marine Fisheries Service (NMFS) priorities and National Oceanic and Atmospheric Administration’s (NOAA’s) Healthy Ocean Goal. In particular, it is hoped that a proactive and comprehensive strategic plan based on a predictable schedule and geographic area rotation will facilitate the continuation, and in some cases, the initial implementation of, research that will provide the majority of data required to meet NMFS’ cetacean-related mandates.

Download or read book Ecological Complexity written by Alkistis Elliott-Graves and published by Cambridge University Press. This book was released on 2023-08-10 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complexity has received substantial attention from scientists and philosophers alike. There are numerous, often conflicting, accounts of how complexity should be defined and how it should be measured. Much less attention has been paid to the epistemic implications of complexity, especially in Ecology. How does the complex nature of ecological systems affect ecologists' ability to study them? This Element argues that ecological systems are complex in a rather special way: they are causally heterogeneous. Not only are they made up of many interacting parts, but their behaviour is variable across space or time. Causal heterogeneity is responsible for many of the epistemic difficulties that ecologists face, especially when making generalisations and predictions. Luckily, ecologists have the tools to overcome these difficulties, though these tools have historically been considered suspect by philosophers of science. The author presents an updated philosophical account with an optimistic outlook of the methods and status of ecological research.

Download or read book Scenarios and Responses to Future Deep Oil Spills written by Steven A. Murawski and published by Springer. This book was released on 2019-07-04 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has often been said that generals prepare for the next war by re-fighting the last. The Deepwater Horizon (DWH) oil spill was unlike any previous – an underwater well blowout 1,500 meters deep. Much has been learned in the wake of DWH and these lessons should in turn be applied to both similar oil spill scenarios and those arising from “frontier” explorations by the marine oil industry. The next deep oil well blowout may be at 3,000 meters or even deeper. This volume summarizes regional (Gulf of Mexico) and global megatrends in marine oil exploration and production. Research in a number of key areas including the behavior of oil and gas under extreme pressure, impacts on biological resources of the deep sea, and the fate of oil and gas released in spills is synthesized. A number of deep oil spills are simulated with detailed computer models, and the likely effects of the spills and potential mitigation measures used to combat them are compared. Recommended changes in policies governing marine oil exploration and development are proposed, as well as additional research to close critical and emerging knowledge gaps. This volume synthesizes state-of-the-art research in deep oil spill behavior and response. It is thus relevant for government and industry oil spill responders, policy formulators and implementers, and academics and students desiring an in-depth and balanced overview of key issues and uncertainties surrounding the quest for deep oil and potential impacts on the environment.

Download or read book Wildlife and Wind Farms Conflicts and Solutions written by Martin Perrow and published by Pelagic Publishing Ltd. This book was released on 2019-08-01 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind farms are an essential component of global renewable energy policy and the action to limit the effects of climate change. There is, however, considerable concern over the impacts of wind farms on wildlife, leading to a wide range of research and monitoring studies, a growing body of literature and several international conferences on the topic. This unique multi-volume work provides a comprehensive overview of the interactions between wind farms and wildlife. Volume 4 provides a state-of-the-science guide to monitoring and mitigation to minimise or even eliminate impacts on wildlife from offshore wind farms. The survey and monitoring section includes detailed chapters on fish and invertebrate communities, marine mammals and seabirds, and a chapter dedicated to the use of tracking technology applied to birds. The section continues with a chapter on collision risk and population modelling that underpins much current impact assessment, and a chapter detailing how collision risk for birds and bats may be monitored at sea. The mitigation section comprises chapters outlining mitigation options and strategies for birds and bats, and how to mitigate the effects of noise, especially during construction, on marine mammals and fish. A chapter on perspectives on marine spatial planning as applied to wind farms concludes the volume. The authors have been carefully selected from across the globe from the large number of academics, consultants and practitioners now engaged in wind farm studies, for their influential contribution to the science. Edited by Martin Perrow and with contributions by over 40 leading researchers including: Aonghais Cook, Thomas Dahlgren, Johann Köppel, Meike Scheidat, Henrik Skov, Chris Thaxter & Frank Thomsen. The authors represent a wide range of organisations and institutions including the Universities of Gothenberg, Ghent, Highlands & Islands and Wageningen, Chalmers University of Technology and Technical University of Berlin, British Trust for Ornithology, The Carbon Trust, Institute of Avian Research Vogelwarte Helgoland, Institute for Applied Ecosystem Research (IfAÖ), Norwegian Institute for Nature Research (NINA) and Sea Mammal Research Unit (SMRU); as well as several leading consultancies. Each chapter includes informative figures, tables, photographs and detailed case studies. Several of the latter are produced stand-alone from invited specialists to ensure geographic spread and to showcase exciting new research. This book is designed as the definitive guide on the topic for practitioners, researchers, managers and planners as well as students in higher education engaged in studies of the environment, ecology, climate change, conservation and impact assessment.

Download or read book Assessing Cetacean Surveys Throughout the Mediterranean Sea a Gap Analysis in Environmental Space written by Laura Mannocci and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Heterogeneous data collection in the marine environment has led to large gaps in our knowledge of marine species distributions. To fill these gaps, models calibrated on existing data may be used to predict species distributions in unsampled areas, given that available data are sufficiently representative. Our objective was to evaluate the feasibility of mapping cetacean densities across the entire Mediterranean Sea using models calibrated on available survey data and various environmental covariates. We aggregated 302,481 km of line transect survey effort conducted in the Mediterranean Sea within the past 20 years by many organisations. Survey coverage was highly heterogeneous geographically and seasonally: large data gaps were present in the eastern and southern Mediterranean and in non-summer months. We mapped the extent of interpolation versus extrapolation and the proportion of data nearby in environmental space when models calibrated on existing survey data were used for prediction across the entire Mediterranean Sea. Using model predictions to map cetacean densities in the eastern and southern Mediterranean, characterised by warmer, less productive waters, and more intense eddy activity, would lead to potentially unreliable extrapolations. We stress the need for systematic surveys of cetaceans in these environmentally unique Mediterranean waters, particularly in non-summer months

This book was released on 2018-11-05 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists and natural resource managers are charged with making complex management decisions in the face of a rapidly changing environment resulting from climate change, energy development, urban sprawl, invasive species and globalization. Advances in Geographic Information System (GIS) technology, digitization, online data availability, historic legacy datasets, remote sensors and the ability to collect data on animal movements via satellite and GPS have given rise to large, highly complex datasets. These datasets could be utilized for making critical management decisions, but are often “messy” and difficult to interpret. Basic artificial intelligence algorithms (i.e., machine learning) are powerful tools that are shaping the world and must be taken advantage of in the life sciences. In ecology, machine learning algorithms are critical to helping resource managers synthesize information to better understand complex ecological systems. Machine Learning has a wide variety of powerful applications, with three general uses that are of particular interest to ecologists: (1) data exploration to gain system knowledge and generate new hypotheses, (2) predicting ecological patterns in space and time, and (3) pattern recognition for ecological sampling. Machine learning can be used to make predictive assessments even when relationships between variables are poorly understood. When traditional techniques fail to capture the relationship between variables, effective use of machine learning can unearth and capture previously unattainable insights into an ecosystem's complexity. Currently, many ecologists do not utilize machine learning as a part of the scientific process. This volume highlights how machine learning techniques can complement the traditional methodologies currently applied in this field.
Download or read book Mixed Species Groups of Animals written by Eben Goodale and published by Academic Press. This book was released on 2017-04-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed-Species Groups of Animals: Behavior, Community Structure, and Conservation presents a comprehensive discussion on the mixed-species groups of animals, a spectacular and accessible example of the complexity of species interactions. They are found in a wide range of animals, including invertebrates, fish, mammals and birds, and in different habitats, both terrestrial and aquatic, throughout the world. While there are more than 500 articles on this subject scattered in separate categories of journals, there has yet to be a general, cross-taxa book-length introduction to this subject that summarizes the behavior and community structure of these groups. The authors first survey the diversity of spatial associations among animals and then concentrate on moving groups. They review the major classes of theories that have been developed to explain their presence, particularly in how groups increase foraging efficiency and decrease predation. Finally, they explore the intricacies of species interactions, such as communication, that explain species roles in groups and discuss what implications these social systems have for conservation. Functions as a single resource for readers inside and outside of academia on mixed-species groups, serving as a foundation for future research in this field Begins with an empirical summary of mixed-species distribution and reviews how the theories explaining their adaptive benefits are supported by the evidence Includes many aspects of mixed-group behavior (e.g. foraging, communication, collective decision-making, dominance, social roles of species and leadership, relationship to conservation) that were not previously or easily accessible
