Download or read book Volume 1 Seabird Biodiversity and Human Activities written by Jaime A. Ramos and published by CRC Press. This book was released on 2022-06-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seabirds are global travellers connecting oceans and seas all over the world, and facing multiple threats at local and global scales. Seabirds are long-lived top predators, reflecting changes at lower trophic levels, and are good models to assess ecological changes produced by human societies. Thus, world-wide collaborations are needed to understand seabird ecology and to develop effective conservation measures benefitting both humans and seabird populations. This book provides a modern overview on seabird biodiversity studies: it begins by covering the most up-to-date techniques to study seabirds, and then focus on pragmatic issues related with interactions between seabirds and humans, the use of seabirds as ecological indicators and conservation of seabirds. It gives an updated insight on all these topics and highlights gaps that need further development for a comprehensive understanding of the relationships between seabirds and human actions. This book covers the response of the seabird research community to a biodiversity crisis aiming to contribute towards environmental sustainability. It should provide inspiration to a wide range of professionals and students, including the much needed world-wide collaboration between research groups and practitioners. In this way seabird research and conservation provide an inspiration for the solution of global issues such as climate change.
Download or read book Adaptation and Evolution in Marine Environments Volume 2 written by Cinzia Verde and published by Springer Science & Business Media. This book was released on 2012-10-29 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume of “Adaptation and Evolution in Marine Environments – The Impacts of Global Change on Biodiversity” from the series “From Pole to Pole” integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present ) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

Download or read book Seabird Ecology written by R. W. Furness and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics.
Download or read book Heavy Metals in the Marine Environment written by Robert W. Furness and published by CRC Press. This book was released on 2018-01-18 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.

Download or read book Marine Ecosystems and Global Change written by Manuel Barange and published by OUP Oxford. This book was released on 2010-02-11 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global environmental change (including climate change, biodiversity loss, changes in hydrological and biogeochemical cycles, and intensive exploitation of natural resources) is having significant impacts on the world's oceans. This book advances knowledge of the structure and functioning of marine ecosystems, and their past, present, and future responses to physical and anthropogenic forcing. It illustrates how climate and humans impact marine ecosystems, providing a comprehensive review of the physical and ecological processes that structure marine ecosystems as well as the observation, experimentation, and modelling approaches required for their study. Recognizing the interactive roles played by humans in using marine resources and in responding to global changes in marine systems, the book includes chapters on the human dimensions of marine ecosystem changes and on effective management approaches in this era of rapid change. A final section reviews the state of the art in predicting the responses of marine ecosystems to future global change scenarios with the intention of informing both future research agendas and marine management policy. Marine Ecosystems and Global Change provides a detailed synthesis of the work conducted under the auspices of the Global Ocean Ecosystems Dynamics (GLOBEC) programme. This research spans two decades, and represents the largest, multi-disciplinary, international effort focused on understanding the impacts of external forcing on the structure and dynamics of global marine ecosystems.
Download or read book Threats to the Arctic written by Scott Elias and published by Elsevier. This book was released on 2021-06-18 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Threats to the Arctic discusses all the current threats to this fragile region, emphasizing the interconnections between many environmental impacts, as well as the teleconnections between events already emerging in the Arctic (ocean circulation changes, melting of sea ice, glaciers and ice sheets) and other parts of the world. The book's aim is to inform readers about the impending, sometimes irreversible changes coming to the Arctic. University students, environmental engineers, policymakers and sociologists with an interest in the role of the Arctic in global change will benefit from the book's unique perspective. As this remote, inhospitable part of the world that few people will ever visit provides amazing insights, we can no longer have an 'out of sight – out of mind' approach to the environmental upheavals taking place in the Arctic. - Provides the most up-to-date information on this rapidly changing, critical part of the world - Offers a holistic understanding of the interconnections between global environmental changes and impacts in the Arctic - Examines fact-based pressure on politics and industry to preserve Arctic biota and environments
