Book excerpt: "This Progress Report describes the progress made from 2009 to 2014 toward meeting the recovery objectives listed in the Recovery Strategy for the North Atlantic Right Whale (Eubalaena glacialis) in Canadian Waters (hereafter "Recovery Strategy). This report is one in a series of documents for this species that are linked and should be considered together, including a recovery potential assessment (DFO 2007), the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report (COSEWIC 2013), a Recovery Strategy (DFO 2014a), and any future Action Plans. Section 2 reproduces the COSEWIC assessment summary, recaps the threats to the population and its critical habitat, along with the recovery objectives, performance indicators, and the critical habitat schedule of studies from the Recovery Strategy. During the reporting period, many activities were undertaken to support the recovery objectives. These activities, along with an assessment of recovery progress according to the performance indicators, are presented in Section 3. Section 4 provides a concluding statement about the implementation of the Recovery Strategy during the reporting period, as well as suggestions to guide future recovery efforts"--Intro.

Download or read book Marine Faunal Diversity in India written by Krishnamoorthy Venkataraman and published by Academic Press. This book was released on 2014-11-21 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 70% of the earth's surface is covered by water, making it an ideal and abundant resource for studying species diversity, faunal communities, and ecosystems. India's massive coastline (5,044 miles) means it plays a major role in housing these faunal communities. Of the 32 animal phyla, 15 are represented in India's marine ecosystem, covering more than 15,000 species. Marine and coastal ecosystems of India provide supporting services in the form of wide range of habitats. Major ecosystems such as estuaries, mangroves, coral reefs, lagoons, seaweeds and sea grasses serve as nurseries for both inshore and offshore fishes and others, many of which are supposed to be commercially exploited. Marine Faunal Diversity in India describes different marine faunal group ranges from sponges, corals, mollusks, crabs, fishes, reptiles, birds, marine mammals, mangrove fauna and tsunami impact on marine faunal diversity. The chapters, written by reputed experts in their respective fields, illustrate diversity and distribution of marine faunal communities. Key aspects of the ecology and conservation of this important ecosystem are also discussed. Marine Faunal Diversity in India provides marine biologists and related researchers with access to the latest research and field studies from this major region. - Provides the latest field research on marine faunal diversity throughout the vast and species-rich Indian region - Brings together expertise from top marine biology researchers in the country - Covers a diverse array of aquatic environments, including coastal and island areas - Discusses conservation ecology of marine faunal groups
Download or read book Biology and Ecology of Antarctic Krill written by Volker Siegel and published by Springer. This book was released on 2016-08-03 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

Download or read book Passive Acoustic Monitoring of Cetaceans written by Walter M. X. Zimmer and published by Cambridge University Press. This book was released on 2011-04-21 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore exploration. Walter Zimmer provides an integrated approach to PAM, combining physical principles, discussion of technical tools and application-oriented concepts of operations. Additionally, relevant information and tools necessary to assess existing and future PAM systems are presented, with Matlab code used to generate figures and results so readers can reproduce data and modify code to analyse the impact of changes. This allows the principles to be studied whilst discovering potential difficulties and side effects. Aimed at graduate students and researchers, the book provides all information and tools necessary to gain a comprehensive understanding of this interdisciplinary subject.

Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?
Download or read book The Gray Whale Eschrichtius Robustus written by Mary Lou Jones and published by Academic Press. This book was released on 2012-12-02 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.
Download or read book Nondestructive Biomarkers in Vertebrates written by Cristina Fossi and published by CRC Press. This book was released on 2020-01-29 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive Biomarkers in Vertebrates presents an innovative approach for hazard assessment in vertebrates based on nondestructive rather than destructive methods. The book reviews the state of the art and defines the development and validation procedure of this new strategy. Biological materials, such as blood samples, epithelial tissue, eggs, feathers, and feces that can be obtained without stress or damage to the animal are suggested. Certain traditional studies (blood esterases, blood chemistry, mixed function oxidases, porphyrins, DNA damage, and cytological changes) can be performed on these specimens, along with new tests requiring only very small samples. This approach is developed to benefit protected, threatened species whose existence cannot be further jeopardized by the use of destructive methods. This volume will be particularly useful to ecotoxicologists, wildlife protection personnel, environmental consultants, and conservationist organizations.
