Download or read book Ecotoxicology of Antifouling Biocides written by Takaomi Arai and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of alternative compounds must be controlled to avoid such errors. These and other findings are described and concisely summarized in this book, providing a useful reference in countries where alternative biocides are being considered. Included are studies on the effects on marine organisms, making this book an excellent aid to experts in environmental chemistry, to government organizations, and to students.

Download or read book Reproductive Sciences in Animal Conservation written by Pierre Comizzoli and published by Springer Nature. This book was released on 2019-08-30 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences. Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.

Download or read book Physiology of the Cladocera written by Nikolai N. Smirnov and published by Academic Press. This book was released on 2017-06-01 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology of the Cladocera, Second Edition, is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable review is based on the world's literature, including Russian research not previously widely available, and offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution. It features the addition of new sections and a vast amount of new information, such as the latest data on feeding, nutrition, pathological physiology, chemical composition, neurosecretion, and behavior, as well as hormonal regulation, antioxidants, and the biochemical background of effects of natural and anthropogenic factors. Additional expertly updated contributions in genetics and cytology, and a new chapter in embryology, round out the physiological chapters, and provide comprehensive insight into the state of knowledge of Cladocera and their underlying mechanisms. Cladocera crustaceans have become globally studied for many purposes, including genetic, molecular, ecological, environmental, water quality, systematics, and evolutionary biology research. Since the genome of Daphnia was sequenced and published, that system has gained much wider exposure, also leading to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics as well as ecogenomic toxicology. However, the physiological background on Cladocera has been fragmentary (including on the other 700 known species besides Daphnia), despite the extensive literature on species identification and morphology. This work addresses this issue by collecting and synthesizing from the literature the state of knowledge of cladoceran physiology, including discussion on both adequately and inadequately investigated fields, and thus directions of future research. - Summarizes fundamental information obtained in recent years, including on steroids, antioxidants, hormones, nanoparticles, and impact of wastewater of pharmaceutical industries - Provides the foundational information needed for scientists and practitioners from a variety of fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, comparative physiology, limnology, zoology–carcinology, and water quality assessment - Features coverage of both Daphniids and representatives of other families, with attention drawn to little-studied aspects of their physiology, especially of those living in the litt oral zone - Includes guidance to the literature on cladoceran physiology in four languages - Discusses advantages and shortcomings of Cladocera as experimental animals and indicators of water quality

Download or read book Puberty from Bench to Clinic written by J.-P. Bourguignon and published by Karger Medical and Scientific Publishers. This book was released on 2015-12-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Puberty is a unique paradigm for the understanding of gene-environment interaction and developmental programming. Therefore, normal and abnormal pubertal development can be divided and examined in three sections: the role of genetic factors, the role of environmental factors (including nutrition) and therapeutic issues in disorders of puberty. Dealing with all of these sections and framed along current key concepts in pediatric endocrinology, experts share their view on critical issues such as weighting of genetic versus environmental factors or the impact of environmental factors in relation to critical periods in development. Not only showing the consensus and controversial issues in the various areas, each chapter presents lessons for clinical management in an attempt to link basic research, physiology and pathophysiology with the clinical management of pubertal disorders. Puberty from Bench to Clinic bridges up-to-date concepts from animal and human physiology and pathology towards a better understanding and management of pubertal disorders, making it a unique resource for researchers in the field of development and reproduction, clinical scientists and practitioners in neuro-, pediatric and adolescent endocrinology as well as gynecology.

This book was released on 2012 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In May 2009, the Government of Canada, through the Pest Management Regulatory Agency (PMRA) of Health Canada, asked the Council of Canadian Academies to appoint an expert panel to answer the question, "What is the scientific status of the use of integrated testing strategies in the human and environmental regulatory risk assessment of pesticides?" The charge to the Panel was further specified in a series of sub-questions: [1] What is the state of the science of the tools and data sources associated with integrated testing strategies? [2] What is the current status of the use of integrated testing strategies for the risk assessment of pesticides, pharmaceuticals, industrial chemicals, and other chemical substances by regulatory agencies around the world? [3] Could there be potential impacts on the public's perception and confidence in regulatory risk assessment and risk management decisions for pesticides if integrated testing strategies were implemented?"--P. xiii-xiv.

This book was released on 2000-02-03 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.
