The Geographical Distribution of Animals by Alfred Russel Wallace Pdf
"Wallace, together with Darwin was the founder of modern evolutionary theory, and when Darwin received Wallace's paper of 1858 (a year before the publication of the Origin of Species), he wrote to Lyell "All my originality, whatever it may amount to, will be smashed"."I never saw a more striking coincidence.Your words (referring to Lyell's earlier warnings that Darwin might be anticipated) have come true with a vengeance." In 1858 Wallace was already preparing an announcement of an importent zoogeographical discovery, which proposed a boundary line dividing the archipelago of Indo-Malayan and Australian zoological regions. The culmination of Wallace's approach was achieved in his monumental two-volume "The geographical Distribution." and it is a pioneer-work in zoogeography."--Abebooks website.
Identification and Geographical Distribution of the Mosquitoes of North America, North of Mexico by Richard F. Darsie,Ronald A. Ward Pdf
"This is the identification manual for North American mosquitoes."--Choice "The essential resource for anyone concerned with mosquito control or biology."--American Reference Books Annual "A valuable resource. . . . This book is the collective product of two very competent scientists."--Journal of Medical Entomology "For the dedicated mosquito worshipper! This book is undoubtedly a must and with its beautifully illustrated keys sets a high standard to follow."--Parasitology Because of the occurrence of mosquito-borne diseases and the widespread distribution of mosquitoes as pests to humans, professionals must know how to identify them. With its wealth of information, this book is the only one of its kind available for specialists working on mosquito-borne diseases and in mosquito control units, and for introductory and advanced students who study entomology. This book updates the successful guide to North American mosquitoes published by the American Mosquito Control Association in 1981. It includes 12 new species that have since been added to the North American mosquito fauna, revised distribution maps of all species, and revised and completely illustrated identification keys for the adult females and fourth instar larvae of all 174 species and subspecies known to occur in North America, north of Mexico. Including 9 exotic species that have been introduced and today successfully thrive in North America, this book's usefulness to mosquito control programs cannot be overestimated.
Protist Diversity and Geographical Distribution by W. Foissner,David Leslie Hawksworth Pdf
Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups of organisms on earth. They are generally treated as a separate kingdom, commonly named Protista (or Protoctista) in textbooks, but in reality they are a mixture of organisms with disparate a?nities. Some authors have hypothesized that the numbers of protists are not especially large, and that many have extraordinarily wide distributions. However, the p- ture that unfolds from the latest studies discussed in this issue is di?erent. There are many species with wide ranges, and proportionately more cosmopolitan species than in macroorganism groups, as a result of their long evolutionary histories, but there are also de?nite patterns and geographical restrictions to be found. Further, some protists are linked to host organisms as mutualists or parasites and necessarily con?ned to the distributions of their hosts.
The Geographical Distribution of Animal Viral Diseases by Stewart Hal Pdf
The Geographical Distribution of Animal Viral Diseases attempts to shed some light on the global distribution of 110 different viral diseases, mainly of livestock and companion animals. The world literature was screened for 110 different viruses, and maps were prepared. These maps delineate the global distribution of pathogenic viruses based on authenticated reports from a variety of reliable sources. Four viruses were categorized as affecting more than one species to a significant degree (astrovirus, rabies, rotaviruses, and Rift Valley fever). The largest number of maps involved viruses that affect humans. Of the 28 viruses a large number were from the California encephalitis group. Ten of the 28 viruses were reported only in the Eastern Hemisphere, 14 only in the Western Hemisphere, and four were worldwide. Birds were the next most frequently affected group with the 15 viruses, followed by pigs with 14 viruses. Overall the vector-borne viruses appear to have much sharper and clear-cut geographical boundaries than the others.
How streaming services and internet distribution have transformed global television culture. Television, once a broadcast medium, now also travels through our telephone lines, fiber optic cables, and wireless networks. It is delivered to viewers via apps, screens large and small, and media players of all kinds. In this unfamiliar environment, new global giants of television distribution are emerging—including Netflix, the world’s largest subscription video-on-demand service. Combining media industry analysis with cultural theory, Ramon Lobato explores the political and policy tensions at the heart of the digital distribution revolution, tracing their longer history through our evolving understanding of media globalization. Netflix Nations considers the ways that subscription video-on-demand services, but most of all Netflix, have irrevocably changed the circulation of media content. It tells the story of how a global video portal interacts with national audiences, markets, and institutions, and what this means for how we understand global media in the internet age. Netflix Nations addresses a fundamental tension in the digital media landscape – the clash between the internet’s capacity for global distribution and the territorial nature of media trade, taste, and regulation. The book also explores the failures and frictions of video-on-demand as experienced by audiences. The actual experience of using video platforms is full of subtle reminders of market boundaries and exclusions: platforms are geo-blocked for out-of-region users (“this video is not available in your region”); catalogs shrink and expand from country to country; prices appear in different currencies; and subtitles and captions are not available in local languages. These conditions offer rich insight for understanding the actual geographies of digital media distribution. Contrary to popular belief, the story of Netflix is not just an American one. From Argentina to Australia, Netflix’s ascension from a Silicon Valley start-up to an international television service has transformed media consumption on a global scale. Netflix Nations will help readers make sense of a complex, ever-shifting streaming media environment.
