Book excerpt: Excerpt from A Determination of the Economic Status of the Western Meadowlark (Sturnella Neglecta) In California The investigation has consisted primarily of field investiga tion, experimentation, and stomach examination. A large part of the field work has been carried on at Lathrop, San Joaquin County, California, a place admirably suited for the work in hand. Duties on the agricultural and horticultural demonstra tion train, which toured the. State in 1911 and 1912 under the auspices of the Department of Agriculture of the University of California and the Southern Pacific Railway Company, have afiorded additional opportunity to study conditions from one end of the state to the other. Economic ornithology is a new science and has hardly pro gressed further than the stage of preliminary interest and study. As a result practically all of the work attempted thus far has been of the extensive rather than of the intensive sort, and has been made up largely of a study of the food of birds. In this investigation the attempt has been made' to improve on past methods and, by determining the food of birds taken in the same locality each month, or twice each month, to furnish reliable evidence as to their food throughout the whole year. A study of the bird in the field, its depredations, and its life-history, has also been made in order that all available evidence might be obtained. Considerable difficulty has been experienced in that there has been, and now is, a difference of Opinion as to the criteria to be used in the determination of the economic status of a bird. The ideas which have been advanced in the past, and even those of the present day, appear to be unsatisfactory, or at least nu trustworthy. It seemed, therefore, that a review of past methods, with the addition of such new ones as appeared to be valuable, might prove not only interesting but of considerable value to future workers in the field. A similar lack of information re garding methods of stomach examination has been evident. A detailed account of the method used in this investigation, there fore seems justified.

Book excerpt: When the young Swedish-descended Alexandra Bergson inherits her father's farm in Nebraska, she must transform the land from a wind-swept prairie landscape into a thriving enterprise. She dedicates herself completely to the land—at the cost of great sacrifices. O Pioneers! [1913] is Willa Cather's great masterpiece about American pioneers, where the land is as important a character as the people who cultivate it. WILLA CATHER [1873-1947] was an American author. After studying at the University of Nebraska, she worked as a teacher and journalist. Cather's novels often focus on settlers in the USA with a particular emphasis on female pioneers. In 1923, she was awarded the Pulitzer Prize for the novel One of Ours, and in 1943, she was elected to the American Academy of Arts and Sciences.

Book excerpt: In the late 19th century, orphaned Jim Burden is sent to the wilderness in Nebraska to live with his grandparents. He arrives at the same time as the Shimerda family, including the eldest daughter Ántonia, who becomes his closest neighbors. Life in the American West is tough, especially for the impoverished Shimerda family, and pioneers must struggle for survival. A friendship blossoms between Jim and Ántonia as they explore nature and have adventures together, a friendship that will last a lifetime. My Ántonia became an immediate success when first published and is today considered Willa Cather's first masterpiece. It is praised for its depiction of the American West and its ability to highlight the aspirations of ordinary, poor people in a time when it was customary to write about the elite.

Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.
