Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Grazing animals enjoy an ambiguous reputation in the field of nature conservation. Livestock are often treated as a scourge, yet native large herbivores form the prime attraction of many a reserve. This book gives the first comprehensive overview of the use of grazing as a tool in conservation management. Considering in turn the ecological and historical background, the impact of grazing on community structure, management applications and future prospects, this book examines issues such as the role of herbivores as keystone species, the assessment of habitat quality and the function of scientific models in advancing grazing management. Large herbivores are shown to be potentially powerful allies in the management of nature reserves, particularly in the maintenance, enhancement or restoration of biodiversity. Grazing and Conservation Management will appeal to conservation biologists and rangeland managers, providing them with a clearer understanding of grazing and conservation management. 232 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At the turn of the century gynecology had achieved independence from surgery in most medical schools; although gynecologists were surgeons, their interests were turning toward nonsurgical aspects of their specialty. In 1900, merely two years after the Curies' discovery, radium was first used as a treatment for carcinoma of the cervix. In that day cervical cancer claimed more women's lives than any other malignancy and was described by Wil liam P. Graves, the second professor of gynecology at Harvard as follows: 'Cancer of the cervix may rightly be termed of all tumors one of the most deadly and most ghastly. It kills by slow torture, causing in later stages months of agonizing pain and producing a discharge of such a foul and nauseating character as to repel proper medical assistance. Nurses declined to care for these cases, while many public hospitals closed their wards to them as patients. ' In late twentieth century parlance the dramatic results of radium therapy would indeed have been called a 'breakthrough' and radium techniques, later combined with external irradiation, were devel oped by gynecologists, no longer just surgeons. Pathology was the basic science of gynecology and gynecologists with a special interest in pathology served as pathologist to the departments of gynecology. As late as 1970 six months of the three-year residency program in obstetrics and gynecology at Harvard were devoted to formal training in pathology. 408 pp. Englisch.…
