CATEGORIES OF CLASSIFICATION. From the time that Linnaeus showed us the necessity of a scientific system as a framework for the arrangement of scientific facts in Natural History, the number of divisions adopted by zoologists and botanists increased steadily. Not only were families, orders, and classes added to genera and species, but these were further multiplied by subdivisions of the different groups. But as the number of divisions increased, they lost in precise meaning, and it became more and more doubtful how far they were true to Nature. Moreover, these divisions were not taken in the same sense by all naturalists: what were called families by some were called orders by others, while the orders of some were the classes of others, till it began to be doubted whether these scientific systems had any foundation in Nature, or signified anything more than that it had pleased Linnaeus, for instance, to call certain groups of animals by one name, while Cuvier had chosen to call them by another. These divisions are, first, the most comprehensive groups, the primary divisions, called branches by some, types by others, and divided by some naturalists into so-called sub-types, meaning only a more limited circumscription of the same kind of group; next we have classes, and these also have been divided into sub-classes; then orders and sub-orders; families and sub-families or tribes; then genera, species, and varieties. With reference to the question whether these groups really exist in Nature, or are merely the expression of individual theories and opinions, it is worth while to study the works of the early naturalists, in order to trace the natural process by which scientific classification has been reached; for in this, as in...

Download or read book Patterns of Vertebrate Biology written by E.W. Jr. Jameson and published by Springer. This book was released on 1981-06-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book grew from a series of lectures on vertebrate natural history. The topics have been developed over a period of nearly 30 years, and today scarcely resemble the original subject matter. The progress is primarily technical. Some concepts provide a synthetic framework for viewing much modern research, but many of these concepts either date from Darwin or have developed from obser vations of later students. Animal science courses follow a sequential pattern in which there are three discrete levels of undergraduate instruction. Initially, students study subject mat ter contained in such courses as biology and general zoology. These courses intro duce students to animal phylogeny, basic plans of morphology and certain phys iological aspects; incidental to these subjects the student acquires a broad zoological vocabulary. At the other end of the academic spectrum are courses that emphasize synthe sis and theory: evolution, zoogeography, behavior and ecology are important courses whose role is to explore the relationships of various aspects of the physical and biological world. In these courses theory and analysis prevail. They are not, however, essentially "subject matter" courses with distinct bodies of knowledge.
Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book excerpt: Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.
Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.
