A colorfully decorated Christmas tree, lit with twinkling lights, provokes awe and delight. We understand the lighted tree as a central symbol of the Christmas season, but what are the roots of the tradition? Who first thought to bedeck a tree, to bring it inside? How and where did the local activity grow into a widespread tradition, and how has the Christmas tree traveled across time and continents? Bernd Brunner's brief history—enriched by a selection of delightful and unusual historic...

A blend of history, science, philosophy, and environmentalism, The Tree is an engaging and elegant look at the life of the tree and what modern research tells us about their future.There are redwoods in California that were ancient by the time Columbus first landed, and pines still alive that germinated around the time humans invented writing. There are Douglas firs as tall as skyscrapers, and a banyan tree in Calcutta as big as a football field.Fr...

An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The Third Edition of this book retains the aim of the first in presenting the principles of mineral nutrition in the light of current advances. This volume retains the structure of the first edition, being divided into two parts: Nutritional Physiology and Soil-Plant Relationships. In Part I, more emphasis has been placed on root-shoot interactions, stress physiology, ...

Name the five Great Trees of Ireland? What trees are most often found beside holy wells or cemeteries? Which tree gave the Red Branch Knights of Ulster their name? Ireland was once so heavily wooded it was said a squirrel could travel from Cork to Killarney without touching the ground. So it is no surprise that, in ancient Ireland, mythology and folklore were a part of the people's general knowledge about trees. Many of the myths and legends and much of the folklore associated with native ...

Just a week after the Kristallnacht terror in 1938, young Luzie Hatch, a German Jew, fled Berlin to resettle in New York. Her rescuer was an American-born cousin and industrialist, Arnold Hatch. Arnold spoke no German, so Luzie quickly became translator, intermediary, and advocate for family left behind. Soon an unending stream of desperate requests from German relatives made their way to Arnold’s desk.   Luzie Hatch had faithfully preserved her letters both to and from far-flung...

This fully revised and expanded edition of Fundamentals of Soil Ecology continues its holistic approach to soil biology and ecosystem function. Students and ecosystem researchers will gain a greater understanding of the central roles that soils play in ecosystem development and function. The authors emphasize the increasing importance of soils as the organizing center for all terrestrial ecosystems and provide an overview of theory and practice of soil ecology, both from an ecosystem and e...

The media coverage of natural disasters (hurricanes, fires, floods, ice storms, etc.) indicates the prevalence of natural disasters in most, if not all, ecosystems. In order for scientists to study, understand, and ultimately predict how these disturbances affect ecosystems, it is necessary for them to know more about the physical processes involved in these disturbances and to learn how to couple these processes to the ecological systems. Essential for all ecologists, forest researchers, ...

In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly.

The purpose of this book is to assess the potential effects of biotechnological approaches particularly genetic modification on biodiversity and the environment. All aspects of biodiversity such as ecological diversity, species diversity and genetic diversity are considered. Higher organisms contain a specific set of linear DNA molecules called chromosomes and a complete set of chromosomes in an organism comprises its genome. The collection of traits displayed by any organism (phenotype) d...
