Available in PDF, EPUB and Kindle. Book excerpt: La formation des couples et la sélection sexuelle, l'accouplement et la ponte, les soins parentaux. Une subtile biologie de la sexualité et des comportements reproductifs d'une remarquable diversité, parmi les plus variés de tous les vertébrés. Bien que leurs mécanismes génétiques et leurs processus physiologiques soient communs à tous les vertébrés, les poissons se singularisent par d'étonnantes capacités à mettre en œuvre des tactiques et des stratégies reproductives convenablement adaptées aux variations spatiales et temporelles de leur environnement aquatique et aux fluctuations de leurs relations sociales. Une telle "inventivité" leur a permis de traverser jusqu'à nous les diverses ères géologiques, quelles qu'aient été les conditions environnementales, et d'occuper, de nos jours, tous les systèmes aquatiques. Éco-éthologie de la reproduction des poissons fait le point sur l'état des connaissances actuelles relatives à la biologie, à l'écologie et à l'éthologie de la reproduction, à la lumière des travaux les plus récents, réalisés, à la fois, par des observations en milieu naturel et en conditions expérimentales de laboratoire. Il permettra au lecteur de se persuader que, loin d'être des vertébrés "inférieurs" comme le présuppose leur position dans la "systématique" du règne animal, les poissons sont des organismes dont de nombreux comportements reproductifs peuvent être fort complexes, à l'image de ceux des anguilles, des saumons, des bouvières, des amphiprions. Cet ouvrage est destiné aux enseignants et étudiants de 2e et 3e cycles en biologie, écologie, éthologie, hydrobiologie, environnement, ainsi qu'aux ingénieurs et techniciens chargés de l'aménagement et de la protection des milieux naturels. Il sera également d'un grand intérêt pour les responsables des aquariums publics et les aquariophiles, les aquaculteurs, les pêcheurs et les écologistes.
Download or read book Intertidal Fishes written by Michael H. Horn and published by Elsevier. This book was released on 1998-11-03 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intertidal Fishes describes the fishes inhabiting the narrow strip of habitat between the high and low tide marks along the rocky coastlines of the world. It analyzes the specialized traits of these fishes that have adapted to living in the dynamic and challenging space where they are alternately exposed to the air and submerged in water with the ebb and flow of the tides. This book provides a comprehensive account of fishes largely overlooked in many previous studies of intertidal organisms and emphasizes how they differ from fishes living in other deeper-water habitats. Coverage includes air breathing, movements and homing, sensory systems, spawning and parental care, feeding habits, community structure, systematic relationships, distribution patterns, and the fossil record in the intertidal zone. Written by an international team of 21 experts on intertidal fish biology Worldwide coverage of intertidal fishes Comprehensive phylogenetic listing of all fish families with intertidal members Global biogeographic analysis involving over 700 species from 86 sites Outlines field and laboratory methods pertinent to studying intertidal fishes Thorough ecological coverage with chapters on vertical distribution, movements and homing, reproduction, feeding, and community structure Covers the physiology of aerial and aquatic respiration, osmoregulation, and sensory systems

Download or read book Edible Sea Urchins Biology and Ecology written by John M. Lawrence and published by Elsevier. This book was released on 2006-12-07 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Subsequent chapters consider the ecology of individual species that are of major importance ecologically and economically. These include species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. * First comprehensive book devoted to the biology and ecology of sea urchins * NEW chapter on Nutrition of Sea Urchins and Ecology of Diadema * Brand NEW illustrations * Hot NEW topic: Immunology of the Sea Urchin * Chapters written by internationally recognized experts * Each chapter revised and updated from the first edition * Biological chapters include reproduction, endocrinology, carotenoids and disease * Ecological chapters include species of major economic interest for fisheries and aquaculture
Download or read book The Violence of Modernity written by Debarati Sanyal and published by JHU Press. This book was released on 2020-03-03 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Violence of Modernity turns to Charles Baudelaire, one of the most canonical figures of literary modernism, in order to reclaim an aesthetic legacy for ethical inquiry and historical critique. Works of modern literature are commonly theorized as symptomatic responses to the trauma of history. In a climate that tends to privilege crisis over critique, Debarati Sanyal argues that it is urgent to rethink literary experience in terms that recall its contestatory potential. Examining Baudelaire's poems afresh, she shifts the focus of critical attention toward an account of modernism as an active engagement with violence, specifically the violence of history in nineteenth-century France. Sanyal analyzes a literary current that uses the traditional hallmarks of modernism—irony, intertextuality, self-reflexivity, and formalism—to challenge the historical violence of modernity. Baudelaire and the committed ironists writing in his wake teach us how to read and resist the violence of history, and thereby to challenge the melancholy tenor of our contemporary "wound culture." In a series of provocative readings, Sanyal presents Baudelaire's poetry as an aesthetic form that contests historical violence through rhetorical strategies of complicity, counterviolence, and critique. The book develops a new account of Baudelaire's significance as a modernist by dislodging him both from his traditional status as a practitioner of "art for art's sake" and from his more recent incarnation as the poet of trauma. Following her extended analysis of Baudelaire's poetry, Sanyal in later chapters considers a number of authors influenced by his strategies—including Rachilde, Virginie Despentes, Albert Camus, and Jean-Paul Sartre—to examine the relevance of their interventions for our current climate of trauma and terror. The result is a study that underscores how Baudelaire's legacy continues to energize literary engagements with the violence of modernity.
Download or read book The Cichlid Fishes written by George Barlow and published by Basic Books. This book was released on 2008-12-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cichlid fishes are amazing creatures. In terms of sheer number of species, they are the most successful of all families of vertebrate animals, and the extent and speed with which they have evolved in some African lakes has made them the darlings of evolutionary biologists. But what truly captivates biologists like George Barlow -- not to mention thousands of aquarists the world over -- is the complexity of their social lives and their devotion to family (most species of cichlids are monogamous and many pairs share the responsibility of raising offspring). In this wonderful book, Barlow describes the unusually high intelligence of these fishes, their complex mating and parenting rituals, their bizarre feeding and fighting habits, and the unusual adaptations and explosive rate of speciation that have enabled them to proliferate and flourish. A celebration of their diversity, The Cichlid Fishes is also a marvelous exploration of how these unique animals might help resolve the age-old puzzle of how species arise and evolve.

Available in PDF, EPUB and Kindle. Book excerpt: INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.
Download or read book Conservation of Endangered Freshwater Fish in Europe written by Arthur Kirchhofer and published by Birkhäuser. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.
