Download or read book The Rasputin Effect When Commensals and Symbionts Become Parasitic written by Christon J. Hurst and published by Springer. This book was released on 2016-07-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.
Download or read book Essential Oils in Food Preservation Flavor and Safety written by Victor R Preedy and published by Academic Press. This book was released on 2015-09-28 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential Oils in Food Preservation, Flavor and Safety discusses the major advances in the understanding of the Essential Oils and their application, providing a resource that takes into account the fact that there is little attention paid to the scientific basis or toxicity of these oils.

Download or read book Yeasts in Natural Ecosystems Ecology written by Pietro Buzzini and published by Springer. This book was released on 2017-10-05 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an up-to-date review of the ecology of yeast communities in natural ecosystems. It focuses on their biological interactions, including mutualism, parasitism, commensalism and antagonistic interactions, and is closely connected with the volume Yeasts in Natural Ecosystems: Diversity by the same editors. Yeasts are the smallest eukaryotic organisms successfully growing under a wide range of environmental conditions. They constantly modify the environment through their own metabolic activities. Although yeasts are among the earlier colonizers of nutrient-rich substrates, their role in ecosystem processes is not limited to the consumption and transformation of simple sugars. They also engage in close relationships with animals, plants and other fungi in the environment as mutualists, competitors, parasites and pathogens. This book reviews the diversity of biological interactions and roles of yeasts in ecosystems and summarises recent concepts and tools developed in community ecology. All of the chapters were written by leading international yeast research experts, and will appeal to researchers and advanced students in the field of microbial ecology.

Download or read book Darwin s Roadmap to the Curriculum written by Glenn Geher and published by Oxford University Press. This book was released on 2019-05-01 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a paradox when it comes to Darwinian ideas within the academy. On one hand, Darwin's theories have famously changed the foundational ideas related to the origins of life, shaping entire disciplines in the biological sciences. On the other hand, people in educated societies across the globe today are famously misinformed and uneducated about Darwinian principles and ideas. Applications of evolutionary theory outside the traditional areas of biology have been slow to progress, and scholars doing such work regularly run into all kinds of political backlash. However, a slow but steady push to advance the teaching of evolution across academic disciplines has been under way for more than a decade. This book serves to integrate the vast literature in the interdisciplinary field of Evolutionary Studies (EvoS), providing clear examples of how evolutionary concepts relate to all facets of life. Further, this book provides chapters dedicated to the processes associated with an EvoS education, including examples of how an interdisciplinary approach to evolutionary theory has been implemented successfully at various colleges, universities, and degree programs. This book also offers chapters outlining a variety of applications to an evolution education, including improved sustainable development, medical practices, and creative and critical thinking skills. Exploring controversies surrounding evolution education, this volume provides a roadmap to asking and answering Darwinian questions across all areas of intellectual inquiry.

Download or read book Field Crop Arthropod Pests of Economic Importance written by Peter A. Edde and published by Academic Press. This book was released on 2021-08-21 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. Includes insect synonyms, common names, and geographic distribution Provides information on natural enemies Is thoroughly referenced for future research

Download or read book The Tears of Re written by Gene Kritsky and published by Oxford University Press. This book was released on 2015-10-08 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to Egyptian mythology, when the ancient Egyptian sun god Re cried, his tears turned into honey bees upon touching the ground. For this reason, the honey bee was sacrosanct in ancient Egyptian culture. From the art depicting bees on temple walls to the usage of beeswax as a healing ointment, the honey bee was a pervasive cultural motif in ancient Egypt because of its connection to the sun god Re. Gene Kritsky delivers a concise introduction of the relationship between the honey bee and ancient Egyptian culture, through the lenses of linguistics, archeology, religion, health, and economics. Kritsky delves into ancient Egypt's multifaceted society, and traces the importance of the honey bee in everything from death rituals to trade. In doing so, Kritsky brings new evidence to light of how advanced and fascinating the ancient Egyptians were. This richly illustrated work appeals to a broad range of interests. For archeology lovers, Kritsky delves into the archeological evidence of Egyptian beekeeping and discusses newly discovered tombs, as well as evidence of manmade hives. Linguists will be fascinated by Kritsky's discussion of the first documented written evidence of the honeybee hieroglyph. And anyone interested in ancient Egypt or ancient cultures in general will be intrigued by Kritsky's treatment of the first documented beekeepers. This book provides a unique social commentary of a community so far removed from modern humans chronologically speaking, and yet so fascinating because of the stunning advances their society made. Beekeeping is the latest evidence of how ahead of their times the Egyptians were, and the ensuing narrative is as captivating as every other aspect of ancient Egyptian culture.
