Download or read book Floral Biology written by David G. Lloyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Available in PDF, EPUB and Kindle. Book excerpt: “A triumph of science writing, a well crafted, deeply researched story of politics, ethics, and the fascinating lives of humans and bees.” —Jonathan Eig, New York Times–bestselling author We think of bees as being among the busiest workers in the garden, admiring them for their productivity. But amid their buzzing, they are also great communicators—and unusual dancers. As Karl von Frisch (1886–1982) discovered during World War II, bees communicate the location of food sources to each other through complex circle and waggle dances. As Tania Munz shows in this exploration of von Frisch’s life and research, this important discovery came amid the tense circumstances of the Third Reich. The Dancing Bees draws on previously unexplored archival sources in order to reveal von Frisch’s full story, including how the Nazi government in 1940 determined that he was one-quarter Jewish, revoked his teaching privileges, and sought to prevent him from working altogether until circumstances intervened. In the 1940s, bee populations throughout Europe were facing the devastating effects of a plague (just as they are today), and because the bees were essential to the pollination of crops, von Frisch’s research was deemed critical to maintaining the food supply of a nation at war. The bees, as von Frisch put it years later, saved his life. Munz not only explores von Frisch’s complicated career in the Third Reich, she looks closely at the legacy of his work and the later debates about the significance of the bee language and the science of animal communication. “Will surely become a classic in the literature on the history of biology in the twentieth century.” —Thomas D. Seeley, author of Honeybee Democracy

Download or read book A Philosophy of the Insect written by Jean-Marc Drouin and published by Columbia University Press. This book was released on 2019-10-01 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of insects is at once beneath our feet and unfathomably alien. Small and innumerable, insects surround and disrupt us even as we scarcely pay them any mind. Insects confront us with the limits of what is imaginable, while at the same time being essential to the everyday functioning of all terrestrial ecosystems. In this book, the philosopher and historian of science Jean-Marc Drouin contends that insects pose a fundamental challenge to philosophy. Exploring the questions of what insects are and what scientific, aesthetic, ethical, and historical relationships they have with humanity, he argues that they force us to reconsider our ideas of the animal and the social. He traces the role that insects have played in language, mythology, literature, entomology, sociobiology, and taxonomy over the centuries. Drouin emphasizes the links between humanistic and scientific approaches—how we have projected human roles onto insects and seen ourselves in insect form. Caught between the animal and plant kingdoms, insects force us to confront and reevaluate our notions of gender, family, society, struggle, the division of labor, social organization, and individual and collective intelligence. A remarkably original and thought-provoking work, A Philosophy of the Insect is an important book for animal studies, environmental ethics, and the history and philosophy of science.

Download or read book Darwin s Sciences written by Duncan Porter and published by John Wiley & Sons. This book was released on 2015-06-08 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete scientific biography of Darwin that takes into account the latest research findings, both published and unpublished, on the life of this remarkable man. Considered the first book to thoroughly emphasize Darwin’s research in various fields of endeavor, what he did, why he did it, and its implications for his time and ours. Rather than following a strictly chronological approach - a narrative choice that characteristically offers an ascent to On the Origin of Species (1859) with a rapid decline in interest following its publication and reception - this book stresses the diversity and full extent of Darwin’s career by providing a series of chapters centering on various intellectual topics and scientific specializations that interested Darwin throughout his life. Authored by academics with years of teaching and discussing Darwin, Darwin's Sciences is suited to any biologist who is interested in the deeper implications of Darwin's research.
