Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Standard Natural History, Vol. 5: Mammals In the beginning of the third volume of tills series we have a general account of the anatomy and physiology of the branch of Vertebrata; and here, as an introduction to the class of Mammals, we need only to refer very briefly to some of the special diagnostic characters which separate this group from the other divisions of backboned animals. In this account we have intentionally omitted those features which are common to all ertebrates, and all description of physiological phenomena which, as explained in the ordinary school text-books of human physiology, will apply as well to the whole class of mammals as to man. The Mammalia, the highest class of the animal kingdom, is more distinctly marked off from all other groups than are many of the classes considered in the preceding volumes. While there frequently exists a doubt as to the proper boundaries of some of the lower groups, or their relative importance in the scale of perfection, no such hesitancy is felt regarding the limits or the grade of the mammalia. Even within the limits of the class the orders are all well defined, and in most cases their relative rank is pretty well settled. This superiority of the mammalia over all other classes of the animal kingdom does not imply that every organ is more perfect or better adapted to its purpose, or that every individual is really higher; but that when we come to regard the totality of the organization, and the setting apart of portions of the body for some specific purpose, resulting in an increased differention of organs and an increased complexity of the organism, upon which alone the relative rank of animal rests, the higher rank is at once evident. Thus the human eye, far from being the perfect organ described in some works of a teleological tendency, is less perfect than that of the eagle in many respects, and yet no one would think on this account of placing the bird of prey higher than man. Like all vertebrates, the mammals never have more than two pairs of limbs, but with the exception of some of the aquatic forms (whale, etc.), these two pairs are always present, whence the name in frequent use for the class - quadrupeds. The anterior pair of limbs are never absent in the group. Except in a few forms, to be noted below, the body is covered with hair. The mouth is usually armed with teeth. The heart is four-chambered, and the circulation is complete. The blood is warm and contains non-nucleated red corpuscles. The body cavity is divided into two portions by a transverse muscle, the diaphragm, or "midriff," the anterior portion being called the pleural, and the posterior, or abdominal portion, the peritoneal cavity. The young are born alive, and are afterward nourished by milk, secreted by milkglands (mammce), whence the name of the class.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Standard Natural History, Vol. 1 In so far as this is a process of growth, accompanied by the assumption of a defi nite form, it might be compared with the growth of a crystal of salt in brine; but, on closer examination, it turns out to be something very different. For the crystal of salt grows by taking to itself the salt contained in the brine, which is added to its exterior; whereas the plant grows by addition to its interior; and there is not a trace of the characteristic compounds of the plant's body, albumen, gluten, starch, or cellulose, or fat, in the soil, or in the water, or in the air. Yet the plant creates nothing, and therefore the matter of the proteids and amy loids and fats which it contains must be supplied to it, and simply manufactured, or combined in new fashions, in the body of the plant.

Download or read book A Natural History of the Future written by Rob Dunn and published by Hachette UK. This book was released on 2022-01-20 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past century, our species has made unprecedented technological innovations with which we have sought to control nature. In A Natural History of the Future, biologist Rob Dunn argues that such efforts are futile. We may see ourselves as life's overlords, but we are instead at its mercy. In the evolution of antibiotic resistance, the power of natural selection to create biodiversity, and even the surprising life of the London Underground, Dunn finds laws of life that no human activity can annul. When we create artificial islands of crops, dump toxic waste, or build communities, we provide new materials for old laws to shape. Life's future flourishing is not in question. Ours is. A Natural History of the Future sets a new standard for understanding the diversity and destiny of life itself.

Download or read book Water written by Alice Outwater and published by Basic Books. This book was released on 2008-08-06 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: An environmental engineer turned ecology writer relates the history of our waterways and her own growing understanding of what needs to be done to save this essential natural resource. Water: A Natural History takes us back to the diaries of the first Western explorers; it moves from the reservoir to the modern toilet, from the grasslands of the Midwest to the Everglades of Florida, through the guts of a wastewater treatment plant and out to the waterways again. It shows how human-engineered dams, canals and farms replaced nature's beaver dams, prairie dog tunnels, and buffalo wallows. Step by step, Outwater makes clear what should have always been obvious: while engineering can de-pollute water, only ecologically interacting systems can create healthy waterways. Important reading for students of environmental studies, the heart of this history is a vision of our land and waterways as they once were, and a plan that can restore them to their former glory: a land of living streams, public lands with hundreds of millions of beaver-built wetlands, prairie dog towns that increase the amount of rainfall that percolates to the groundwater, and forests that feed their fallen trees to the sea.

Download or read book North American Watersnakes written by J. Whitfield Gibbons and published by University of Oklahoma Press. This book was released on 2004 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.

Download or read book The Future of Natural History Museums written by Eric Dorfman and published by Routledge. This book was released on 2017-10-12 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural history museums are changing, both because of their own internal development and in response to changes in context. Historically, the aim of collecting from nature was to develop encyclopedic assemblages to satisfy human curiosity and build a basis for taxonomic information. Today, with global biodiversity in rapid decline, there are new reasons to build and maintain collections, while audiences are more diverse, numerous, and technically savvy. Institutions must learn to embrace new technology while retaining the authenticity of their stories and the value placed on their objects. The Future of Natural History Museums begins to develop a cohesive discourse that balances the disparate issues that our institutions will face over the next decades. It disassembles the topic into various key elements and, through commentary and synthesis, explores a cohesive picture of the trajectory of the natural history museum sector. This book contributes to the study of collections, teaching and learning, ethics, and running non-profit businesses and will be of interest to museum and heritage professionals and academics and senior students in Biological Sciences and Museum Studies.
