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
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.

Book Description
Some trees and birds are made for each other. Take, for example, the whitebark pine, a timberline tree that graces the moraines and ridgetops of the northern Rockies and the Sierra Nevada-Cascades system. This lovely five-needled pine, long-lived and rugged though it is, cannot reproduce without the help of Clark's nutcracker. And the nutcracker, though it captures insects in the summer and steals a bit of carrion, cannot raise its young in these alpine habitats without feeding them the nutritious seeds of the whitebark pine. Between them, these dwellers of the high mountains provide for each others' posterity, which leads biologists to label their relationship symbiotic, or mutualistic. But there is more to it than that, because in playing out their roles these partners change the landscape. The environment they create provides life's necessities to many other plants and animals. Working in concert, Clark's nutcracker and the whitebark pine build ecosystems. In Made for Each Other: A Symbiosis of Birds and Pines, Ronald M. Lanner details for the first time this fascinating relationship between pine trees and Corvids (nutcrackers and jays), showing how mutualism can drive not only each others' evolution, but affect the ecology of many other members of the surrounding ecosystem as well. Lanner explains that many of the world's pines have seeds not adapted to wind dispersal. Fortunately, their seeds are harvested from the cone and scattered over many miles by seed-eating jays and nutcrackers who bury millions of seeds in the soil as a winter food source. Remarkably, these "pine nut" dependent birds can find their caches even through deep snow. Seeds left in the soil germinate, perpetuating the pines and guarantee future seeds for future birds. Moreover, the newly "planted" whitebark pine groves encourage further tree growth, such as Engelmann spruce, and eventually the patches of open-grown woodland coalesce, forming a continuous forest. Large forest stands offer cover for large animals like bear, elk, and moose, and provide territories for Red Squirrels. These squirrels also depend on pine seeds as a food source, storing large quantities of seeds on the ground, piled up against fallen logs or stumps, or buried in the forest litter. In the fall both black and grizzly bears are preparing to hibernate and must increase their stores of body fat. The seeds of whitebark pine are large and very rich, containing sixty to seventy percent fat, and are an ideal food for this purpose. The large seed reserves created by the squirrels become a feasting ground for these bears. Meanwhile, the sun-loving trees shaded out by the maturing decay offer housing for cavity-nesters like woodpeckers and nuthatches, as well as a breeding ground for fungi which are eagerly devoured by mule deer and red squirrels in search of protein. Eventually, when the forest is ignited in one of the thunderstorms so common and so violent in the high country, an open area is created, attracting nutcrackers in need of a new cache site, and the cycle begins again. Focusing on the Rocky Mountains and the American Southwest, and ranging as far afield as the Alps, Finland, Siberia, and China, this beautifully illustrated and gracefully written work illuminates the phenomenon of co-evolution.

Book Description
Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.

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.
