"What are the lives of trees, of conifers, like'. . . How do seedlings establish and develop into saplings? How do some seedlings stay alive for decades, marking time in the deep shade of the forest? How do the distinctive forms of saplings of the different species arise'. . . When, how, and where do cones come from? What is the sex life of a conifer? Where does pollen come from? What does pollen do?" - From the Introduction A comparative account of the coniferous trees indigenous to Northeastern North America Extensively illustrated with full-colour photographs, diagrams, and drawings by the author, Graham R. Powell's Lives of Conifers examines the complex and fascinating life cycles of the 12 coniferous trees that grow naturally in northeastern North America on both sides of the Canada-U.S. border. Tracing their development from seeds and seedlings, to saplings, through the pole stage to maturity, old age, and death, the book is designed to pro-vide a comparison of each species at each stage of life, thus aiding in the recognition and identification of species at all stages of their existence. It includes descriptions of developmental processes and how they differ among the species. The species covered in the book are: the balsam fir, eastern hemlock, tamarack larch, eastern white pine, jack pine, pitch pine, red pine, black spruce, red spruce, white spruce, eastern juniper, and eastern thuja. The book is based almost entirely on what is visible to the careful observer in the forest, and includes only the parts of trees that can be seen above ground. Lives of Conifers will appeal to forest scientists, forestry students, foresters, forest technologists, botanists, horticulturists, arborists, naturalists, and general readers interested in knowing more about their natural surroundings.

Dominant throughout the temperate northern hemisphere, conifers form the backbone of boreal ecosystems. This comprehensive reference work explains the complex life cycles of these trees. Based on more than five decades of study, Graham R. Powell provides an illustrated, guided tour of conifers from seed and reproduction to old age and death. Focusing on the most common species, Powell offers a clear picture of conifers—a type of tree that plays a vital role in various environmental systems and upon which humankind relies for its lifestyle. The engaging text is peppered throughout with interesting facts and comparative data about well- and lesser-known species. The Lives of Conifers features hundreds of full-color illustrations and expansive morphological, anatomical, and physiological information about the evergreens. The book includes a glossary of terms and a detailed bibliography for further study.

When it comes to reproduction, gymnosperms are deeply weird. Cycads and co- fers have drawn out reproduction: at least 13 genera take over a year from polli- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to w- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations. This alternation between diploid and haploid generations was eventually to become one of the key unifying ideas in plant evolution. Dr. Williams points out that alter- tion of generations in conifers shows strong divergence in the evolution of male and female gametes, as well as in the synchronicity of male and female gamete development. How are these coordinated to achieve fertilization? Books on conifer reproduction are all too rare. The only major work in the last generation was Hardev Singh’s 1978 Embryology of Gymnosperms, a book that summarized the previous century’s work. Being a book primarily about embry- ogy, it stopped short of putting conifer reproduction in a genetic or evolutionary context.

This useful manual provides a means for easy identification of the native and cultivated conifers of northeastern North America. The territory covered is roughly eastern Canada and the northeastern fourth of the United States, from Maine south to the southern border of Pennsylvania, west to Kansas, and north to North Dakota. Because it includes so many cultivated species, the book treats the great majority of conifers found in the western United States and Europe as well. Twenty-seven genera and 130 species are included.

This book is the first comprehensive volume on conifers detailing their genomes, variations, and evolution. The book begins with general information about conifers such as taxonomy, geography, reproduction, life history, and social and economic importance. Then topics discussed include the full genome sequence, complex traits, phenotypic and genetic variations, landscape genomics, and forest health and conservation. This book also synthesizes the research included to provide a bigger picture and suggest an evolutionary trajectory. As a large plant family, conifers are an important part of economic botany. The group includes the pines, spruces, firs, larches, yews, junipers, cedars, cypresses, and sequoias. Of the phylum Coniferophyta, conifers typically bear cones and evergreen leaves. Recently, there has been much data available in conifer genomics with the publication of several crop and non-crop genome sequences. In addition to their economic importance, conifers are an important habitat for humans and animals, especially in developing parts of the world. The application of genomics for improving the productivity of conifer crops holds great promise to help provide resources for the most needy in the world.

A compelling account of the extraordinary relatives of ordinary garden conifers. Leading expert Aljos Farjon provides a compelling narrative that observes conifers from the standpoint of the curious naturalist. It starts with the basic question of what conifers are and continues to explore their evolution, taxonomy, ecology, distribution, human uses, and issues of conservation. As the story unfolds many popular misconceptions are dispelled, such as the false notion that all conifers have cones. The extraordinary diversity of conifers begins to dawn as Farjon describes the diminutive creeping shrub Microcachrys tetragona, whose strange seed cones resemble raspberries, and the prehistoric-looking Araucaria meulleri. The taxonomic diversity of conifers is huge and Farjon goes on to relate how, over the course of 300 million years, these trees and shrubs have adapted to survive geological upheavals, climatic extremes, and formidable competition from flowering plants. All who seek to learn more about the early history of life on our planet will cherish this book.
