This book was released on 2018-01-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Story of the Amphibians and the Reptiles Looking more carefully at the difference between the two directions of the new education we can see what each accomplishes. There is first an effort to train the original powers of the individual and make him self-active, quick at observation, and free in his thinking. Next, the new education endeavors, by the reading of books and the study of the wisdom of the race, to make the child or youth a participator in the results of experience of all mankind. These two movements may be made antagonistic by poor teaching. The book knowledge, containing as it does the precious lesson of human experience, may be so taught as to bring with it only dead rules of conduct, only dead scraps of information, and no stimulant to original thinking. Its contents may be memorized without being understood. On the other hand, the self-activity of the child may be stimulated at the expense of his social well-being - his originality may be cultivated at the expense of his rationality. If he is taught persistently to have his own way, to trust only his own senses. To cling to his own Opinions heedless of the experience of his fellows, he is pre paring for an unsuccessful, misanthropic career, and is likely enough to end his life in a madhouse. It is admitted that a too exclusive study of the knowledge found in books, the knowledge which is aggregated from the experience and thought of other people, may result in loading the mind of the pupil with material which he can not use to advantage.

Download or read book A Natural History of Amphibians written by Robert C. Stebbins and published by Princeton University Press. This book was released on 2021-08-10 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book for all readers who want to learn about amphibians, the animal group that includes frogs, toads, salamanders, and caecilians. It draws on many years of classroom teaching, laboratory experience, and field observation by the authors. Robert Stebbins and Nathan Cohen lead readers on a fascinating odyssey as they explore some of nature's most interesting creatures, interspersing their own observations throughout the book. A Natural History of Amphibians can serve as a textbook for students and independent learners, as an overview of the field for professional scientists and land managers, and as an engaging introduction for general readers. The class Amphibia contains more than 4,500 known living species. New species are being discovered so rapidly that the number may grow to more than 5,000 during our lifetimes. However, their numbers are being rapidly decimated around the globe, largely due to the encroachment of humans on amphibian habitats and from growing human-caused environmental pollution, discussed at length in the final chapter. The authors focus our attention on the "natural history" of amphibians worldwide and emphasize their interactions with their environments over time: where they live; how they reproduce; how they have been affected by evolutionary processes; what factors will determine their destinies over time. Through the experienced eyes of the authors, who are skilled observers, we come to see and understand the place of amphibians in the natural world around us.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Amphibia and Reptiles The account of the Amphibia is more complete than that of the Reptilia. It was possible to diagnose practically all the recent genera; and this has been especially done in the Anura, in order to show how in an otherwise very homogeneous group almost any part of the body, internal or external, can be modified in kaleidoscopic variety. The same could not be done with the Reptilia. Their principal groups, - called sub-classes in the present work, in order to emphasise their taxonomic importance in comparison with the main groups of Birds and Mammals.

Download or read book Systematics of the Caecilians Amphibia Gymnophiona written by Denis M. Walsh and published by . This book was released on 1987 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Determining the higher level relationships of the modern amphibian order Gymnophiona (caecilians) poses a number of methodological problems. A cladistic methodology is outlined by which the phylogenetic relationships of this group can be determined objectively. Among the possible sister groups analyzed, which include dissorophid temnospondyls, aistopods, nectrideans, lysorophoids, microsaurs, anurans and urodeles, the microsaurs of the families Gymnarthridae and Goniorhynchidae are the most plausible sister group of caecilians, based on cranial osteology. Hence, the three modern orders of amphibians, caecilians, anurans and urodeles, do not constitute a monophyletic assemblage exclusive of all other groups. Ingroup analysis indicates that the Ichthyophiidae is the most primitive living caecilian family. The cladistic analysis suggests that features of the unique jaw apparatus define two groups of caecilians which diverged, phylogenetically, early in the group's history. Morphometric analysis reveals that elements of the jaw apparatus compose a functional suite of features. Aspects of the development, function, and significance of the jaw to miniaturization of the caecilian skull are inferred from the morphometric analysis."--

Brown and published by PenSoft Publishers LTD. This book was released on 2013-02-07 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long celebrated for its more than 7,100 islands, the Philippines is a country in Southeast Asia that shares only with Madagascar the distinction of having been designated as both a Megadiverse Nation and a Global Biodiversity Conservation Hotspot. The terrestrial vertebrate fauna of the northeastern Philippines, specifically Luzon Island, has been the subject of intense interest since the first historical explorations. Historically, numerous works considered the biodiversity of Luzon as ?depauperate? in the sense that they was presumed to contain a reduced number of species shared with a continental mainland source. This view has persisted until recently, when a renewed interest in faunistic studies of the northern Philippines has produced a series of notable discoveries, drawing attention to high levels of species diversity and endemism in the northern reaches of the archipelago. We provide the first report on the herpetological biodiversity (amphibians and reptiles) of the northern Sierra Madre Mountain Range, northeast Luzon Island, Philippines. We combine new and historical data, and the results of recent fieldwork, to highlight at least 101 species present in this unique region of the archipelago. Not only is this fauna largely endemic (approximately 70%), but also our results add to a nascent body of literature suggesting that the northern portions of the archipelago may be substantially more diverse than currently appreciated.

This book was released on 2012-12-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the evolution and adaptation of amphibians and reptiles, bridging the gulf between the plethora of 'popular' books and the more advanced texts directed towards the needs of specialist research workers, thus making it accessible to advanced students worldwide. It explains basic principles in non-technical terms, and covers the adaptive responses to natural selection which have engendered the diversity of forms that exist in the fossil record and are found in the world today. The book also includes the extinct forms such as dinosaurs, ichthyosaurs and plesiosaurs, and concludes with a dsicussion of relationships with mankind and the preservation of diversity. XXXXXXX Neuer Text This title is an introduction to the evolution and adaptation of amphibians and reptiles, which is accessible to a wide range of readers. Basic principles are explained in non-technical terms, and the adaptive responses to natural selection which have engendered the diversity of forms that exist in the fossil record and that are found in the world today are covered. In the concluding chapter, the relationship between mankind and the preservation of diversity is discussed.
