Available in PDF, EPUB and Kindle. Book excerpt: A tiny organism called pollen pulls off one of nature’s key tasks: plant reproduction. Pollination involves a complex network of different species interacting with one another and mutually adapting to their ecosystems, which are constantly changing. Some pollen grains require just a puff of wind to set them in motion, but most plants depend on creatures gifted with mobility. These might be birds, bats, reptiles, or insects including butterflies, beetles, flies, wasps, and over twenty thousand species of bee. In Paths of Pollen Stephen Humphrey asks readers to imagine a tipping point where plants and pollinators can no longer adapt to stressors such as urbanization, modern agriculture, and global climate change. Illuminating the science of pollination ecology through evocative encounters with biologists, conservationists, and beekeepers, Humphrey illustrates the significance of pollination to such diverse concerns as food supply, biodiversity, rising global temperatures, and the resilience of landscapes. As human actions erase habitats and raise the planet’s temperature, plant diversity is dropping and a growing list of pollinators faces decline or even extinction. Paths of Pollen chronicles pollen’s vital mission to spread plant genes, from the prehistoric past to the present, while looking towards an ecologically uncertain future.

Download or read book Annual Plant Reviews Plant Cell Separation and Adhesion written by Jeremy A. Roberts and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell separation is an important process that occurs throughout the life cycle of a plant. It enables the radicle to emerge from the germinating seed, vascular tissue to differentiate, sculpturing of leaves and flowers to take place, pollen to be shed from the mature anther, fruit to soften, senescent and non-functional organs to be lost, and seeds to be shed. In addition to its intrinsic scientific interest, many of the developmental processes to which it contributes have importance for agriculture and horticulture. This is the first volume to focus exclusively on these processes and to link improvements in our scientific understanding with methods that may allow us to manipulate cell separation and adhesion to the benefit of the agricultural and horticultural industries. It will therefore be of interest to the experimental scientist and to those who wish to apply these techniques commercially.
Download or read book Physiology of Cotton written by James McD. Stewart and published by Springer Science & Business Media. This book was released on 2009-11-04 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.

This book was released on 2022-11-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A quiet, poetic, and exquisitely gorgeous novel describing a wandering mythic figure in a Kyoto monastery, by the National Book Award winner The grandson of Prince Genji lives outside of space and time and wanders the grounds of an old monastery in Kyoto. The monastery, too, is timeless: a place of prayer and deliverance, with barely a trace of any human presence. The wanderer is searching for a garden that has long captivated him: “he continually saw the garden in his mind’s eye without being able to touch its existence.” This exquisitely beautiful novel by National Book Award–winner László Krasznahorkai—perhaps his most serene and poetic work—describes a search for the unobtainable and the riches to be discovered along the way. Despite the difficulties in finding the garden, the reader is closely introduced to the construction processes of the monastery (described in poetic detail) as well as the geological and biological processes of the surrounding area (the underground layers revealed beneath a bed of moss, the travels of cypress-tree seeds on the wind, feral foxes and stray dogs meandering outside the monastery’s walls), making this an unforgettable meditation on nature, life, history, and being.

Download or read book Physiology Promiscuity and Prophecy at the Millennium written by Bruce J. West and published by World Scientific. This book was released on 1999 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the development of a theory of complex phenomena, using such concepts as fractals, chaos, and fractional derivatives; but, most important, the idea of an allometric control process is developed. In summary the theory attempts to explain why the distribution in the intensity of wars is the same as the relative frequency of the number of words used in languages and the number of species evolved over time from one or a few remote ancestors. The theory also describes the similarity in the variability of the number of births to teens in Texas to the number of sexual partners in homosexual liaisons. The data in both of the aforementioned categories are shown to have long-term memory, and it is this memory that also gives rise to inverse power laws in such physiological phenomena as the interbeat interval distribution of the human heart, the interstride interval distribution in the human gait, and memory in DNA sequences.

Available in PDF, EPUB and Kindle. Book excerpt: The book draws on the evidence of landscape archaeology, palaeoenvironmental studies, ethnohistory and animal tracking to address the neglected topic of how we identify and interpret past patterns of movement in the landscape. It challenges the pessimism of previous generations which regarded prehistoric routes such as hollow ways as generally undatable. The premise is that archaeologists tend to focus on sites while neglecting the patterns of habitual movement that made them part of living landscapes. Evidence of past movement is considered in a multi-scalar way from the individual footprint to the long distance path including the traces created in vegetation by animal and human movement. It is argued that routes may be perpetuated over long timescales creating landscape structures which influence the activities of subsequent generations. In other instances radical changes of axes of communication and landscape structures provide evidence of upheaval and social change. Palaeoenvironmental and ethnohistorical evidence from the American North West coast sets the scene with evidence for the effects of burning, animal movement, faeces deposition and transplantation which can create readable routes along which are favoured resources. Evidence from European hunter-gatherer sites hints at similar practices of niche construction on a range of spatial scales. On a local scale, footprints help to establish axes of movement, the locations of lost settlements and activity areas. Wood trackways likewise provide evidence of favoured patterns of movement and past settlement location. Among early farming communities alignments of burial mounds, enclosure entrances and other monuments indicate axes of communication. From the middle Bronze Age in Europe there is more clearly defined evidence of trackways flanked by ditches and fields. Landscape scale survey and excavation enables the dating of trackways using spatial relationships with dated features and many examples indicate long-term continuity of routeways. Where fields flank routeways a range of methods, including scientific approaches, provide dates. Prehistorians have often assumed that Ridgeways provided the main axes of early movement but there is little evidence for their early origins and rather better evidence for early routes crossing topography and providing connections between different environmental zones. The book concludes with a case study of the Weald of South East England which demonstrates that some axes of cross topographic movement used as droveways, and generally considered as early medieval, can be shown to be of prehistoric origin. One reason that dryland routes have proved difficult to recognise is that insufficient attention has been paid to the parts played by riverine and maritime longer distance communication. It is argued that understanding the origins of the paths we use today contributes to appreciation of the distinctive qualities of landscapes. Appreciation will help to bring about effective strategies for conservation of mutual benefit to people and wildlife by maintaining and enhancing corridors of connectivity between different landscape zones including fragmented nature reserves and valued places. In these ways an understanding of past routeways can contribute to sustainable landscapes, communities and quality of life

Download or read book Pollination in Plants written by Phatlane William Mokwala and published by BoD – Books on Demand. This book was released on 2018-06-06 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are the basic source of food for both humans and animals. Most of the food is made of fruits and seeds. For these to be formed, pollination must first take place. This process is the transfer of pollen grains from the anther, which is the male structure of the flower, to the sigma on the female structure of the flower. The transfer process requires agents to be carried out. The agents can be either biotic or abiotic. Nature perfected this arrangement between the pollination agents and the plants. As ecosystems and agricultural systems are changing, this balanced arrangement becomes disturbed. This makes it necessary that pollination systems be studied so that necessary measures can be undertaken to ensure productivity. The chapters of this book present results in research undertaken to improve productivity in crops such as Actinidia chinensis (the kiwifruit), Theobroma cacao (cocoa), and Manicaria saccifera (a tropical forest palm). Some results are presented on tests to check the viability of pollen grains and the delivery of sperm cells through pollen tubes to the embryo sac. These results can serve as guidelines to any person seeking to improve pollination and productivity or to check the efficiency on pollination in ecosystems or agricultural production systems.
Download or read book The Colonial Shadow written by Kira Celeste and published by Taylor & Francis. This book was released on 2023-02-24 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Colonial Shadow examines the colonial psychology that has shaped what is now known as Canada. This psychology has perpetrated devastating harm over the last half a millennium and continues to oppress Indigenous people and degrade the environment. This book is inspired by the tenet of depth psychology that stories and myths from one’s own ancestry can bring about transformation and deep changes in perspective. As such, it investigates how an alchemical way of imagining into white settler colonial consciousness might contribute to its accountability and psychological healing today. The Colonial Shadow will be an invaluable resource for professionals, academics and students of Jungian and post-Jungian ideas, settler-colonial and First Nations studies, sociology, anthropology, and cultural studies as well as for anyone interested in addressing the colonial complex.
Download or read book Animating Unpredictable Effects written by Jordan Gowanlock and published by Springer Nature. This book was released on 2021 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncanny computer-generated animations of splashing waves, billowing smoke clouds, and characters flowing hair have become a ubiquitous presence on screens of all types since the 1980s. This Open Access book charts the history of these digital moving images and the software tools that make them. Unpredictable Visual Effects uncovers an institutional and industrial history that saw media industries conducting more private R & D as Cold War federal funding began to wane in the late 1980s. In this context studios and media software companies took concepts used for studying and managing unpredictable systems like markets, weather, and fluids and turned them into tools for animation. Unpredictable Visual Effects theorizes how these animations are part of a paradigm of control evident across society, while at the same time exploring what they can teach us about the relationship between making and knowing.
Download or read book The Shamanic Way of the Bee written by Simon Buxton and published by Simon and Schuster. This book was released on 2006-01-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reveals for the first time the ancient tradition of bee shamanism and its secret practices and teachings • Examines the healing and ceremonial powers of the honeybee and the hive • Reveals bee shamanism’s system of acupuncture, which predates the Chinese systems • Imparts teachings from the female tradition and explores the transformative powers of the magico-sexual elixirs they produce Bee shamanism may well be the most ancient and enigmatic branch of shamanism. It exists throughout the world--wherever in fact the honeybee exists. Its medicinal tools--such as honey, pollen, propolis, and royal jelly--are now in common usage, and even the origins of Chinese acupuncture can be traced back to the ancient practice of applying bee stings to the body’s meridians. In this authoritative ethnography and spiritual memoir, Simon Buxton, an elder of the Path of Pollen, reveals for the first time the richness of this tradition: its subtle intelligence; its sights, sounds, and smells; and its unique ceremonies, which until now have been known only to initiates. Buxton unknowingly took his first steps on the Path of Pollen at age nine, when a neighbor--an Austrian bee shaman--cured him of a near-fatal bout of encephalitis. This early contact prepared him for his later meeting with an elder of the tradition who took him on as an apprentice. Following an intense initiation that opened him to the mysteries of the hive mind, Buxton learned over the next 13 years the practices, rituals, and tools of bee shamanism. He experienced the healing and spiritual powers of honey and other bee products, including the “flying ointment” once used by medieval witches, as well as ritual initiations with the female members of the tradition--the Mellisae--and the application of magico-sexual “nektars” that promote longevity and ecstasy. The Shamanic Way of the Bee is a rare view into the secret wisdom of this age-old tradition.
