Download or read book Amphibians of North Africa written by Daniel Escoriza and published by Academic Press. This book was released on 2019-03-16 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region. It is essential to identifying and understanding the ecological role of regional herpetofauna and its conservational importance. It examines the biological origins and diversity of amphibians in North Africa, along with their diverse ecosystems, including deserts, grasslands and subtropical forests. The book features detailed descriptions of the adult and larvae stages of species, such as the North African fire salamander, the common painted frog, Brongersma's toad and the Mediterranean tree frog. This book is a vital resource for herpetology and ecology students and researchers, helping them identify, understand and conserve these amphibians and reptiles in their various habitats across the North African and Mediterranean regions. - Presents the only book on research and species recognition of North West African and Mediterranean amphibians and reptiles in all life phases - Provides novel, iconographic material about little-known species - Features helpful visuals, including ink-drawings, photographs of adult and larvae stages, habitat photographs and distributional maps

Download or read book The Ecology and Behavior of Amphibians written by Kentwood D. Wells and published by University of Chicago Press. This book was released on 2010-02-15 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

This book was released on 2012-12-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the end of the last century and the beginning of this century, the prob lems of immunity in lower vertebrates and the influence of environmental temperature attracted attention for the first time (ERNST, 1890; WIDAL and SICARD, 1897; METCHNIKOFF, 1901). However, relatively little work has been done on this subject until recently. The early investigators were chiefly in terested in the immuno-pathological problems. They immunized various species of lower vertebrates essentially with bacterial vaccines; agglutinating, neutralizing and protective antibodies were detected in their blood. The in fluence of environmental temperature on the immune response was investigated, since this subject represented great economical and theoretical importance. Epizootic diseases were observed to occur in relation to the cold season of the year, when the decrease or spontaneous increase of water temperature occurred (SCHAPERCLAUS, 1965; BESSE et al. , 1965; KLONTZ et al. , 1965 WOOD,1966). The immunological deficiency of fish, caused by their natural or experimental stay in cold water, is now evident for both humoral and cellular immunity. In this review we will focus on two points: We shall attempt (1) to explain the mechanism by which the environmental temperature influences the immune resistance of fish to pathogens, (2) to determine the chronological location of this temperature-sensitive stage in the process of antibody formation, and to make some approaches to the general antibody formation mechanism.
Download or read book Field Guide to the Amphibians and Reptiles of Britain and Europe written by Jeroen Speybroeck and published by Bloomsbury Publishing. This book was released on 2016-07-28 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking new guide is an authoritative field reference for these two groups of animals. The taxonomy and systematics of European reptiles and amphibians have changed a lot in recent years, yet there is no modern, up-to-date field guide available that comprehensively covers all the species. The last illustrated field guide to European reptiles and amphibians was first published 38 years ago, and remains outdated despite occasional reprints and new editions. This major new field guide addresses this deficiency. A total of 219 species are covered in detail, with a focus on identification and geographical variation; species texts also cover distribution, habitat and behaviour. Superb colour illustrations by talented artist Ilian Velikov depict every species and all major variations, and colour photographs are also included for most species. The book includes over 370 colour artworks and 200 colour photographs, 155 accurate and up-to-date distribution maps, and easy-to-use keys and tables to help with swift species identification.

Download or read book The Thin Bone Vault written by Fredric M. Menger and published by World Scientific. This book was released on 2009 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delves into one of the greatest riddles perplexing modern science: ?Why are humans so smart?? In a format understandable even by the non-expert, the author investigates the origins of human intelligence, starting with classical Darwinian concepts. Thus, the strengths and beauty of natural selection are presented with many examples taken from natural history. Common criticisms of Darwin, from scientists and non-scientists alike, are confronted and shown to be either inconclusive or outright false.The author then launches into a discussion of human intelligence, the most important feature of human evolution, and how it cannot be fully explained by mutational selection. Modern humans are smarter than what is demanded by our evolutionary experience as hunter-gatherers. The difficulty lies in the inability of natural selection to answer the following question: how can a complex set of genes, controlling expensive traits with little immediate benefit, come into permanent existence within a short time period in every member of a small population (which was dispersed and geographically isolated over a huge planet) which had a low reproductive output and a low mutation rate?The book concludes with a speculative epigenetic theory of intelligence that does not require DNA mutations as a source of evolution. Although the book is comprehensible by anyone with a college education, this last section in particular should intrigue both layman and expert alike.
