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.

A gripping history that spans law, international affairs, and top-secret technology to unmask the tension between intellectual property rights and national security. At the beginning of the twentieth century, two British inventors, Arthur Pollen and Harold Isherwood, became fascinated by a major military question: how to aim the big guns of battleships. These warships—of enormous geopolitical import before the advent of intercontinental missiles or drones—had to shoot in poor light and choppy seas at distant moving targets, conditions that impeded accurate gunfire. Seeing the need to account for a plethora of variables, Pollen and Isherwood built an integrated system for gathering data, calculating predictions, and transmitting the results to the gunners. At the heart of their invention was the most advanced analog computer of the day, a technological breakthrough that anticipated the famous Norden bombsight of World War II, the inertial guidance systems of nuclear missiles, and the networked “smart” systems that dominate combat today. Recognizing the value of Pollen and Isherwood’s invention, the British Royal Navy and the United States Navy pirated it, one after the other. When the inventors sued, both the British and US governments invoked secrecy, citing national security concerns. Drawing on a wealth of archival evidence, Analog Superpowers analyzes these and related legal battles over naval technology, exploring how national defense tested the two countries’ commitment to individual rights and the free market. Katherine C. Epstein deftly sets out Pollen’s and Isherwood’s pioneering achievements, the patent questions raised, the geopolitical rivalry between Britain and the United States, and the legal precedents each country developed to control military tools built by private contractors. Epstein’s account reveals that long before the US national security state sought to restrict information about atomic energy, it was already embroiled in another contest between innovation and secrecy. The America portrayed in this sweeping and accessible history isn’t yet a global hegemon but a rising superpower ready to acquire foreign technology by fair means or foul—much as it accuses China of doing today.

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.

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.

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, with barely a trace of any human presence. The wanderer is searching for a garden that has long captivated him. This novel by International Booker Prize 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 difficulties in finding the garden, the reader is closely introduced to the construction processes of the monastery as well as the geological and biological processes of the surrounding area, making this an unforgettable meditation on nature, life, history, and being.

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 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.
