Download or read book Current Ornithology written by D.M. Power and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited series has three principal goals. The first is to provide information in a relatively concise way for researchers needing an over view of specific disciplines. The second is to provide an update on specific schools of thought, bringing together ideas from colleagues whose works often appear in a variety of journals. And the third is to stimulate and suggest directions for new research. Volume 6 continues the tradition established by the previous editor and editorial board in providing new information, updating our understanding of specific dis ciplines, and stimulating new research. In the first chapter, Randall Breitwisch examines mortality patterns and sex ratios in monogamous birds. He argues that there are many more components to measuring parental investment than are often re alized; our knowledge is weak in several areas. Understanding the evo lution of mating systems depends on better distinguishing the different intensities of natural selection that operate on males and females. Greg ory Butcher and Sievert Rohwer develop a framework for assessing the role of colorfulness in birds. They propose several hypotheses to test and advocate evaluating more than one hypothesis at a time. Future work on the evolution of distinctive coloration and of sexual and age dimorphism must take these ideas into account.
Download or read book For the Birds written by Marilyn Bailey Ogilvie and published by University of Oklahoma Press. This book was released on 2018-09-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A first-rate ornithologist, Margaret Morse Nice (1883–1974) pioneered field studies on song sparrows and advocated for women’s active role in the sciences. Yet her nontraditional path toward scientific progress, as well as her gender, meant that she had to reach the highest pinnacles of achievement in order to gain prominence in her chosen field. Luckily for Nice, she was more than up to the challenge. In this engaging first book-length biography, Marilyn Bailey Ogilvie sheds light on Nice’s intellectual journey. The wife of an academic, Nice pursued her own scholarly interests through self-study and by cultivating and creating work partnerships with colleagues. Talented, ambitious, and creative, she did not define herself solely through her role as wife and mother, nor did her family responsibilities deter her from her professional achievements. From her undergraduate study at Mount Holyoke College to her fieldwork in Norman, Oklahoma, her coauthorship of Birds of Oklahoma and subsequent correspondence with George Sutton to her later years in Columbus, Ohio, Nice’s career grew in tandem with her personal life—and in some cases, because of it. Although bridled by social constraints, her work spoke for itself: she produced more than 244 papers, articles, and published letters; seven books and book-length monographs; and 3,000 reviews. This voluminous and field-defining output earned her the respect of some of the most important biological scientists of the day, among them Konrad Lorenz and Ernst Mayr, who declared that she had “almost singlehandedly” initiated “a new era in American ornithology.” For the Birds gives Nice her due recognition, lending compelling insight into her activism promoting conservation and preservation, her field methods, and the role of women in the history of science, particularly in ornithology. Nice’s life acts as a looking glass into the various challenges faced by fellow female pioneers, their resolve, and their contributions.

Download or read book The Birds of Africa Volume VIII written by Roger Safford and published by Bloomsbury Publishing. This book was released on 2020-09-17 with total page 1025 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This eighth and final volume covers the Malagasy region which comprises Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, the Comoros, Mauritius and Réunion. Every resident and migrant species is covered in full detail, comparable to other volumes in the series, and with a colour map for each species. Vagrants are treated in less detail. All species are illustrated on a beautiful series of 64 colour plates, with original artwork from John Gale and Brian Small. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.
Download or read book Nature s Diplomats written by Raf De Bont and published by University of Pittsburgh Press. This book was released on 2021-05-11 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nature’s Diplomats explores the development of science-based and internationally conceived nature protection in its foundational years before the 1960s, the decade when it launched from obscurity onto the global stage. Raf De Bont studies a movement while it was still in the making and its groups were still rather small, revealing the geographies of the early international preservationist groups, their social composition, self-perception, ethos, and predilections, their ideals and strategies, and the natures they sought to preserve. By examining international efforts to protect migratory birds, the threatened European bison, and the mountain gorilla in the interior of the Belgian Congo, Nature’s Diplomats sheds new light on the launch of major international organizations for nature protection in the aftermath of World War II. Additionally, it covers how the rise of ecological science, the advent of the Cold War, and looming decolonization forced a rethinking of approach and rhetoric; and how old ideas and practices lingered on. It provides much-needed historical context for present-day convictions about and approaches to the preservation of species and the conservation of natural resources, the involvement of local communities in conservation projects, the fate of extinct species and vanished habitats, and the management of global nature.

Download or read book Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
Download or read book The Herons of Europe written by Claire Voisin and published by A&C Black. This book was released on 2010-10-30 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the majority of the world's Herons live in the tropics and subtropics, Europe is home to nine species, some large, some small, some colonial, some solitary breeders. Highly specialized birds, they exhibit many interesting differences in their behaviour and ecology and are a favourite group for many ornithologists. Voisin begins her book with a general description of the family before going on to treat each species in more detail. The species accounts summarize such topics as field characters, distribution, population size, breeding and feeding ecology and behaviour. Numerous figures and tables are accompanied by fine drawings of behaviour by P. L. Suiro and colour and black and white pictures of each species by Gunnar Brusewitz.
