From Galileo, who used the hollow stalks of grass to demonstrate the idea that peripherally located construction materials provide most of the resistance to bending forces, to Leonardo da Vinci, whose illustrations of the parachute are alleged to be based on his study of the dandelion’s pappus and the maple tree’s samara, many of our greatest physicists, mathematicians, and engineers have learned much from studying plants. A symbiotic relationship between botany and the fields of physics, mathematics, engineering, and chemistry continues today, as is revealed in Plant Physics. The result of a long-term collaboration between plant evolutionary biologist Karl J. Niklas and physicist Hanns-Christof Spatz, Plant Physics presents a detailed account of the principles of classical physics, evolutionary theory, and plant biology in order to explain the complex interrelationships among plant form, function, environment, and evolutionary history. Covering a wide range of topics—from the development and evolution of the basic plant body and the ecology of aquatic unicellular plants to mathematical treatments of light attenuation through tree canopies and the movement of water through plants’ roots, stems, and leaves—Plant Physics is destined to inspire students and professionals alike to traverse disciplinary membranes.

This book covers material taught in a graduate-level soil physics course at Washington State University. While most soil physics courses dwell mainly on deriving rather than solving the differential equations for transport, the author's approach is to focus on solutions. Graduate students in agricultural and biological sciences usually have a good working knowledge of algebra and calculus, but not of differential equations. In order to teach methods for solving very difficult differential equations with difficult boundary conditions using fairly simple mathematical tools, the author uses numerical procedures on microcomputers to solve the differential equations. Numerical methods convert differential equations into algebraic equations which can be solved using conventional methods of linear algebra.This book reflects the philosophy used in the course. Each chapter introduces soil physics concepts, generally in the conventional way. Most chapters then go on to develop simple computer programs to solve the equations and illustrate the points made in the discussion. Problems at the end of each chapter help the reader practice using the concepts introduced in the chapter. The problems and computer programs are an integral part of the presentation, and readers are strongly encouraged to experiment with each model until both the working of the model and the concepts it teaches are familiar. Although the programs are generally short and relatively simple, they are suitable for use as submodels in large, general-purpose models of the soil-plant-atmosphere system, and have been used in this way by the author and by several of his students.Teachers and students alike will welcome this new textbook. It will enable graduate students to understand and solve transport problems which exist in field situations, and will provide them with a good working knowledge of soil physics - fundamental to so many other areas in soil, plant and engineering sciences.

"Physiology," which is the study of the function of cells, organs, and organisms, derives from the Latin physiologia, which in turn comes from the Greek physi- or physio-, a prefix meaning natural, and logos, meaning reason or thought. Thus physiology suggests natural science and is now a branch of biology dealing with processes and activities that are characteristic of living things. "Physicochemical" relates to physical and chemical properties, and "Environmental" refers to topics such as solar irradiation and wind. "Plant" indicates the main focus of this book, but the approach, equations developed, and appendices apply equalIy welI to animaIs and other organisms. We wilI specificalIy consider water relations, solute transport, photosynthesis, transpiration, respiration, and environmental interactions. A physiologist endeavors to understand such topics in physical and chemical terms; accurate models can then be constructed and responses to the internal and the external environment can be predicted. Elementary chemistry, physics, and mathematics are used to develop concepts that are key to under-standing biology -the intent is to provide a rigorous development, not a compendium of facts. References provide further details, although in some cases the enunciated principIes carry the reader to the forefront of current research. Calculations are used to indicate the physiological consequences of the various equations, and problems at the end of chapters provide further such exercises. Solutions to alI of the problems are provided, and the appendixes have a large tist of values for constants and conversion factors at various temperatures.

An exploration of how plant behavior and adaptation offer valuable insights for human thriving. We know that plants are important. They maintain the atmosphere by absorbing carbon dioxide and producing oxygen. They nourish other living organisms and supply psychological benefits to humans as well, improving our moods and beautifying the landscape around us. But plants don’t just passively provide. They also take action. Beronda L. Montgomery explores the vigorous, creative lives of organisms often treated as static and predictable. In fact, plants are masters of adaptation. They “know” what and who they are, and they use this knowledge to make a way in the world. Plants experience a kind of sensation that does not require eyes or ears. They distinguish kin, friend, and foe, and they are able to respond to ecological competition despite lacking the capacity of fight-or-flight. Plants are even capable of transformative behaviors that allow them to maximize their chances of survival in a dynamic and sometimes unfriendly environment. Lessons from Plants enters into the depth of botanic experience and shows how we might improve human society by better appreciating not just what plants give us but also how they achieve their own purposes. What would it mean to learn from these organisms, to become more aware of our environments and to adapt to our own worlds by calling on perception and awareness? Montgomery’s meditative study puts before us a question with the power to reframe the way we live: What would a plant do?

A musical celebration of the garden, from chaff to grass, and all of its lowly weeds, herbs, and creatures Sylvia Legris’s Garden Physic is a paean to the pleasures and delights of one of the world’s most cherished pastimes: Gardening! “At the center of the garden the heart,” she writes, “Red as any rose. Pulsing / balloon vine. Love in a puff.” As if composed out of a botanical glossolalia of her own invention, Legris’s poems map the garden as body and the body as garden—her words at home in the phytological and anatomical—like birds in a nest. From an imagined love-letter exchange on plants between garden designer Vita Sackville-West and Harold Nicolson to a painting by Agnes Martin to the medicinal discourse of the first-century Greek pharmacologist Pedanius Dioscorides, Garden Physic engages with the anaphrodisiacs of language with a compressed vitality reminiscent of Louis Zukofsky’s “80 Flowers.” In muskeg and yard, her study of nature bursts forth with rainworm, whorl of horsetail, and fern radiation—spring beauty in the lines, a healing potion in verse.
