Leaves are all around us—in backyards, cascading from window boxes, even emerging from small cracks in city sidewalks given the slightest glint of sunlight. Perhaps because they are everywhere, it’s easy to overlook the humble leaf, but a close look at them provides one of the most enjoyable ways to connect with the natural world. A lush, incredibly informative tribute to the leaf, Nature’s Fabric offers an introduction to the science of leaves, weaving biology and chemistry with the history of the deep connection we feel with all things growing and green. Leaves come in a staggering variety of textures and shapes: they can be smooth or rough, their edges smooth, lobed, or with tiny te...
Plant volatiles—compounds emitted from plant organs to interact with the surrounding environment—play essential roles in attracting pollinators and defending against herbivores and pathogenes, plant-plant signaling, and abiotic stress responses. Biology of Plant Volatiles, with contributions from leading international groups of distinguished scientists in the field, explores the major aspects of plant scent biology. Responding to new developments in the detection of the complex compound structures of volatiles, this book details the composition and biosynthesis of plant volatiles and their mode of emission. It explains the function and significance of volatiles for plants as well as inse...
Die historisch systematische Studie von Kristina Schierbaum untersucht, unter welchen Umständen Janusz Korczak den Berufswechsel vom Pädiater zum Pädagogen vollzogen hat und richtet unter der Chiffre „Medikalisierung von Kindheit“ den Fokus darauf, wie er in Theorie und Praxis eine Brücke von der Medizin zur Pädagogik schlagen konnte. Abschließend arbeitet sie heraus, welche Vorstellungen Janusz Korczak über das Kind und die Lebensphase Kindheit entwickelt hat, aber auch wie sein Erziehungssystem von den ehemaligen Bewohnern und Bewohnerinnen des Waisenhauses erinnert und mitunter auch kritisch beurteilt wurde.
Plants are sessile, highly sensitive organisms that actively compete for environmental resources both above and below the ground. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences are made possible by parallel sign(alling)-mediated communication processes within the plant body (intraorganismic), between the same, related and different species (interorganismi...
Oxylipins are an important class of signaling molecules in plants, which play an important role in plant defence and innate immunity. Oxylipins have critical roles in plant growth and plant responses to physical damage caused by herbivores, insects, and pathogenic microbes. Over the last decade, our understanding of oxylipin production, metabolism, and function, particularly jasmonates, has advanced considerably. Jasmonates have provided further mechanistic insights into enzyme function and signalling cascades. Other oxylipins, such as hydroxy fatty acids, have recently been shown to exhibit individual signaling features and crosstalk with other phytohormones. There is scant literature on pl...
Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign(aling)- mediated communication processes within archaeal cells (intra-organismic), between the same, related and different archaeal species (interorganismic), and betwee...
Religious, cultural and linguistic diversity has always been a reality in Germany. Yet determining what constitutes success in terms of dealing with diversity on a day-to-day basis is a matter often subject to debate. Demonstrating respect for each other while living together in diversity must be cultivated but also involve the active participation of everyone affected. We experience diversity every day in our communities: in our neighborhoods, schools, at work and in our free time. The "Living Diversity - Shaping Society" publication accompanying the Reinhard Mohn Prize 2018 offers insight into how Germany can effectively target living well together in a multicultural society marked by social inclusion and respect for diversity. It analyzes current approaches in Germany, examines good practices found in other countries and recommends actions that can be taken to cultivate a positive experience with diversity. Contributions by distinguished authors such as Armin Nassehi, Doug Saunders and Bart Somers explore the issue from various viewpoints.
Grafting: do we ever do anything other than that? And are we ever free from vegetal influences when we engage in its operations? For the philosopher Michael Marder, our reflections on vegetal life have a fundamental importance in how we can reflect on our own conceptions of ethics, politics, and philosophy in general. Taking as his starting point the simple vegetal conception of grafting, Marder guides the reader through his concise and numerous reflections on what could be described as a vegetal philosophy. Grafts are transplants either of a shoot inserted into the trunk of another tree or, surgically, of skin (among other living tissues). They are delicate operations intended to preserve, ...
• Explains what an essential oil is and examines the botany of how they evolved and the various roles they play, from protecting the plant to aiding its propagation • Provides in-depth profiles for 58 common essential oils, identifying the phytochemicals that contribute to each oil’s scent and healing qualities and its therapeutic applications, with an emphasis on antimicrobial and antiviral properties • Discusses the healthiest and safest ways to use essential oils for self-care and the safe and appropriate use of essential oils for children, the elderly, and those with compromised immune systems Exploring the journey of essential oils from living plant to bottle, as well as how to ...
