Book Description
Conifers range from familiar pines that grow in almost all parts of the world, to the towering redwoods and sequoias of the American West, to rare plumyews found only in remote Asian forests. these 600 or so species of evergreen trees and shrubs bear their seeds in cones and keep their needlelike leaves through all seasons. Although the conifers are greatly outnumbered by other kinds of plants in the world today, they are an ancient part of the plant kingdom. The Conifer Division explores the origins of these 310-million-year-old plants, as well as their unique physical features and roles in the environment. The Conifer Division also looks at the enormous cultural and economic importance of these plants and at the questions hanging over the fate of the world's last great conifer forests. Book jacket.

Book Description
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.

Book Description
Conifers--pine, fir, and spruce trees--are dominant species in forests around the world. This book focuses on the physiology of conifers and how these physiological systems operate. Special consideration is devoted to the means by which ecophysiological processes influence organismal function and distribution. Chapters focus on the genetics of conifers, their geographic distribution and the factors that influence this distribution, the impact of insect herbivory on ecophysiological parameters, the effects of air pollution, and the potential impact that global climatic changes will have upon conifers. Because of the growing realization that forests have a crucial role to play in global environmental health, this book will appeal to a developing union of ecologists, physiologists and more theoretically minded foresters.

Book Description
A 2014 Choice Magazine "Outstanding Academic Title" An Atlas of the World's Conifers is the first ever atlas of all known conifer species. It is based on locality information of ca. 37,000 collected herbarium specimens held in scientific institutions. As well as providing natural distribution maps for each species, Farjon and Filer give the reader comprehensive insight into the biogeography, diversity and conservation status of conifers on all continents, dispelling the widely held view that they are primarily a northern boreal plant group. Conifer diversity is analysed and presented with a taxonomic and geographic perspective. Distribution patterns are interpreted using the latest information on continental drift, dispersal and phylogeny. The entire dataset supporting the Atlas can be consulted and verified online. These data can also be used for further research and are an invaluable resource for anyone working on conifer systematics, biogeography or conservation. An Atlas of the World’s Conifers indicates the known distribution of all conifers including an analysis of their biogeography, diversity and conservation status. Also available from Brill is Aljos Farjon’s A Handbook of the World's Conifers, published in 2010 (ISBN 978 90 04 17718 5) which is a 2017 Choice Magazine "Outstanding Academic Title".

Book Description
Evergreen your landscape with the beauty and benefits of conifers Growing Conifers is a beautifully photographed, comprehensive gardening guide for selecting and cultivating conifers. Coverage includes: Conifer taxonomy, classification, and geographic distribution Selecting conifers for size, shape, color, and texture Best practices for placement and planting of trees, shrubs, and groundcovers in urban and rural gardens Growing needs and low-input maintenance Building healthy soil, minimizing water stress, and integrated pest management Benefits of conifers including habitat, water and air quality, carbon sequestration, aesthetics, and food. Conifers are often overlooked in gardening and landscaping in favor of deciduous trees and shrubs. Yet conifers come in a wide variety of shapes, sizes, and colors and offer tremendous aesthetic and ecological benefits for any garden. Growing Conifers is an essential, comprehensive resource for gardeners and landscape professionals looking to develop beautiful, sustainable landscapes. ----------------------------------------------------------------------------- New Society Publishers is an activist, solutions-oriented publisher focused on publishing books to build a more just and sustainable future.

Book Description
With the appearance of methods for the sequencing of genomes and less expensive next generation sequencing methods, we face rapid advancements of the -omics technologies and plant biology studies: reverse and forward genetics, functional genomics, transcriptomics, proteomics, metabolomics, the movement at distance of effectors and structural biology. From plant genomics to plant biotechnology reviews the recent advancements in the post-genomic era, discussing how different varieties respond to abiotic and biotic stresses, understanding the epigenetic control and epigenetic memory, the roles of non-coding RNAs, applicative uses of RNA silencing and RNA interference in plant physiology and in experimental transgenics and plants modified to specific aims. In the forthcoming years these advancements will support the production of plant varieties better suited to resist biotic and abiotic stresses, for food and non-food applications.This book covers these issues, showing how such technologies are influencing the plant field in sectors such as the selection of plant varieties and plant breeding, selection of optimum agronomic traits, stress-resistant varieties, improvement of plant fitness, improving crop yield, and non-food applications in the knowledge based bio-economy. - Discusses a broad range of applications: the examples originate from a variety of sectors (including in field studies, breeding, RNA regulation, pharmaceuticals and biotech) and a variety of scientific areas (such as bioinformatics, -omics sciences, epigenetics, and the agro-industry) - Provides a unique perspective on work normally performed 'behind closed doors'. As such, it presents an opportunity for those within the field to learn from each other, and for those on the 'outside' to see how different groups have approached key problems - Highlights the criteria used to compare and assess different approaches to solving problems. Shows the thinking process, practical limitations and any other considerations, aiding in the understanding of a deeper approach
