Available in PDF, EPUB and Kindle. Book excerpt: A Publishers Weekly Best Book One of the New York Public Library's "25 Books to Remember" for 1999 Lavishly illustrated and meticulously researched, filled with fascinating facts and astonishing descriptions of animal behavior, Bruce Bagemihl's Biological Exuberance is a landmark book that will change forever how we look at nature. Homosexuality in its myriad forms has been scientifically documented in more than 450 species of mammals, birds, reptiles, insects, and other animals worldwide. Biological Exuberance is the first comprehensive account of the subject, bringing together accurate, accessible, and nonsensationalized information. Drawing upon a rich body of zoological research spanning more than two centuries, Bagemihl shows that animals engage in all types of nonreproductive sexual behavior. Sexual and gender expression in the animal world displays exuberant variety, including same-sex courtship, pair-bonding, sex, and co-parenting—even instances of lifelong homosexual bonding in species that do not have lifelong heterosexual bonding. Part 1, "A Polysexual, Polygendered World," begins with a survey of homosexuality, transgender, and nonreproductive heterosexuality in animals and then delves into the broader implications of these findings, including a valuable perspective on human diversity. Bagemihl also examines the hidden assumptions behind the way biologists look at natural systems and suggests a fresh perspective based on the synthesis of contemporary scientific insights with traditional knowledge from indigenous cultures. Part 2, "A Wondrous Bestiary," profiles more than 190 species in which scientific observers have noted homosexual or transgender behavior. Each profile is a verbal and visual "snapshot" of one or more closely related bird or mammal species, containing all the documentation required to support the author's often controversial conclusions.

Download or read book Parasites of Marine Fish and Cephalopods written by Sven Klimpel and published by Springer. This book was released on 2019-05-06 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a comprehensive, reliable and practical guide to the dissection and parasitological examination of marine fish and cephalopods. The first part provides a general introduction, presenting basic information on: parasitology, ecology of the marine environment, history and methods of fisheries and aquaculture, as well as the ecology of marine fish and cephalopods and the impact of parasites on hosts. In turn, the second part provides general information on the morphology and anatomy of marine fish and cephalopods using the example of abundant morphotypes (including e.g. habitus photos of the body cavity and internal organs). The third part covers the relevant parasitic groups, their ecology (e.g. lifecycles, transmission), related diseases, and detection. The fourth part, a comprehensive methods section, provides essential protocols and applications of common dissection methods (for roundfish, flatfish and cephalopods) and stomach content analyses, as well as parasite preservation, preparation and molecular identification. Basic calculations of the most common infection and ecological parameters are also introduced. The book’s fifth and final part provides information on health risks associated with fish and cephalopod consumption, as well as the prevention of human infection through the correct handling and processing of fish samples. The appendix provides e.g. blank sheets for recording fish dissections and parasitological examinations.

Download or read book Treatise on Zoology Anatomy Taxonomy Biology The Myriapoda Volume 1 written by Alessandro Minelli and published by BRILL. This book was released on 2011-03-21 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myriapods are the only major zoological group for which a modern encyclopedic treatment has never been produced. In particular, this was the single major gap in the largest zoological treatise of the XIX century (Grassé’s Traité de Zoologie), whose publication has recently been stopped. The two volumes of “The Myriapoda” fill that gap with an updated treatment in the English language. Volume I opens with an introductory treatment of myriapod affinities and phylogeny. The following chapters are mostly devoted to the Chilopoda or centipedes, extensively treated from the point of view of external and internal morphology, physiology, reproduction, development, distribution, ecology, phylogeny and taxonomy. All currently recognized suprageneric and generic taxa are considered. Additional chapters deal with the two smaller myriapod classes, the Symphyla and the Pauropoda. All groups and features are extensively illustrated by line drawings and micrographs and living specimens of representative species of the main groups are presented in color photographs.

Download or read book The Pollution Biology of Aquatic Oligochaetes written by Pilar Rodriguez and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.

Download or read book Biodiversity and Evolution of Parasitic Life in the Southern Ocean written by Sven Klimpel and published by Springer. This book was released on 2017-02-16 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southern Oceans including Antarctic regions are peculiar and very sensitive water biotopes, where animal life and species interrelations are only poorly investigated. Especially the influence of parasites on their host species needs intensive consideration in times of global warming and worldwide pollution. Both factors may influence the finely balanced interrelationships between parasites and endangered hosts especially in specialized regions such as Antarctica. Before this background the present book offers a broad spectrum of important parasite-host interrelations in times of ecosystem changes written by experienced and renown international specialists.

Download or read book Species Conservation in Managed Habitats written by Werner Kunz and published by John Wiley & Sons. This book was released on 2016-08-08 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dieses Praktikerbuch stammt von einem Autor mit langjähriger Erfahrung im Bereich der Ökologie von Insekten und Vögeln und einer herausragenden akademischen Laufbahn in den molekularen Biowissenschaften. Es ist eine willkommene Herausforderung und stellt die weitverbreiteten Ansichten herkömmlicher Umweltpolitik in Frage. Werner Kunz erläutert überzeugend, warum die Aufrechterhaltung einer großen Biodiversität in Europe ganz erheblich von offenen Flächen und karger Vegetation abhängig ist, d. h. Flächen, die weder intensiv nach Aspekten der modernen Landwirtschaft bewirtschaftet noch wieder aufgeforstet werden. Er stellt die weitverbreitete Meinung in Frage, dass Naturschutz mit Artenschutz gleichzusetzen sei, und zeigt, wie bedrohte Tierarten durch ein technisches Design des Lebensraums gerettet werden können. Ein Muss für Umweltbehörden, politische Entscheidungsträger, Ökologen und alle, die Zeuge davon sind, wie aktuell in Zentraleuropa Arten verschwinden.

Download or read book Arthropods as Vectors of Emerging Diseases written by Heinz Mehlhorn and published by Springer Science & Business Media. This book was released on 2012-07-05 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming and globalization are the buzzwords of our time. They have nearly reached a religious status and those who deny their existence are considered modern heretics. Nevertheless, the earth has become an overcrowded village, traversable within a single day. Thus it is hardly surprising that besides persons and goods also agents of disease are easily transported daily from one end of the world to the other, threatening the health and lives of billions of humans and their animals. Agents of diseases (prions, viruses, bacteria, fungi and parasites) are not only transmitted by body contact or direct exchange of bodily fluids, but also by means of vectors which belong to the groups of licking or blood-sucking arthropods (mites, ticks, insects) that live close to humans and their houses. Without a doubt the recently accelerating globalization supports the import of agents of disease into countries where they never had been or where they had long since been eradicated, leading to a false sense of living on a “safe island.” These newly imported or reintroduced diseases – called “emerging diseases” – may lead to severe outbreaks in cases where the countries are not prepared to combat them, or in cases where viruses are introduced that cannot be controlled by medications or vaccines. Arthropods are well known vectors for the spread of diseases. Thus their invasion from foreign countries and their spreading close to human dwellings must be blocked everywhere (in donor and receptor countries) using safe and effective measures. This book presents reviews on examples of such arthropod-borne emerging diseases that lurk on the fringes of our crowded megacities. The following topics show that there is an ongoing invasion of potential vectors and that control measures must be used now in order to avoid disastrous outbreaks of mass diseases.
