Book Description
We are in the midst of a biological revolution. Molecular tools are now providing new means of critically testing hypotheses and models of microevolution in populations of wild, cultivated, weedy and feral plants. They are also offering the opportunity for significant progress in the investigation of long-term evolution of flowering plants, as part of molecular phylogenetic studies of the Tree of Life. This long-awaited fourth edition, fully revised by David Briggs, reflects new insights provided by molecular investigations and advances in computer science. Briggs considers the implications of these for our understanding of the evolution of flowering plants, as well as the potential for future advances. Numerous new sections on important topics such as the evolutionary impact of human activities, taxonomic challenges, gene flow and distribution, hybridisation, speciation and extinction, conservation and the molecular genetic basis of breeding systems will ensure that this remains a classic text for both undergraduate and graduate students in the field.

Book Description
Explains how our plant classification system works and looks at how scientists use it to identify and group plant species. The book also examines the variation between and within plants species and discusses how and why such variations have occurred.

Book Description
"The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.

Book Description
Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume. Ecological Genomics covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. Ecological Genomics covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.

Book Description
Far from being passive elements in the landscape, plants have developed many sophisticated chemical and mechanical means of deterring organisms that seek to prey on them. This volume draws together research from ecology, evolution, agronomy, and plant pathology to produce an ecological genetics perspective on plant resistance in both natural and agricultural systems. By emphasizing the ecological and evolutionary basis of resistance, the book makes an important contribution to the study of how phytophages and plants coevolve. Plant Resistance to Herbivores and Pathogens not only reviews the literature pertaining to plant resistance from a number of traditionally separate fields but also examines significant questions that will drive future research. Among the topics explored are selection for resistance in plants and for virulence in phytophages; methods for studying natural variation in plant resistance; the factors that maintain intraspecific variation in resistance; and the ecological consequences of within-population genetic variation for herbivorous insects and fungal pathogens.

Book Description
Summer Rayne Oakes, an urban houseplant expert and environmental scientist, is the icon of wellness-minded millennials who want to bring nature indoors, according to a New York Times profile. Summer has managed to grow 1,000 houseplants in her Brooklyn apartment (and they're thriving!) Her secret? She approaches her relationships with plants as intentionally as if they were people. Everyone deserves to feel the inner peace that comes from taking care of greenery. Beyond the obvious benefits--beauty and cleaner air--there's a strong psychological benefit to nurturing plants as a path to mindfulness. They can reduce our stress level, lower our blood pressure, and improve our overall outlook. And they offer a rare opportunity to find joy by caring for another living being. When Summer Rayne Oakes moved to Brooklyn from the Pennsylvania countryside, she knew that bringing nature indoors was her only chance to stay sane. She found them by the side of the road, in long-forgotten window boxes, at farmers' markets, and in local garden shops. She found ways to shelve, hang, tuck, anchor, secure, and suspend them. She even installed a 150-foot expandable hose that connects to pipes under her kitchen sink, so she only has to spend about a half-hour a day tending to her plants--an activity that she describes as a "moving meditation." This is Summer's guidebook for cultivating an entirely new relationship with your plant children. Inside, you'll learn to: Pause for the flowers and greenery all around you, even the ones sprouting bravely between cracked pavement Trust that your apartment jungle offers you far more than pretty décor See the world from a plant's perspective, trading modern consumerism for sustainability Serve your chlorophyllic friends by learning to identify the right species for your home and to recreate their natural habitat (Bonus: your indoor garden won't die!) When we become plant parents, we also become better caretakers of ourselves, the people around us, and our planet. So, let's step inside the world of plants and discover how we can begin cultivating our own personal green space--in our homes, in our minds, and in our hearts.
