This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa.
Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales.
This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
This concise guide shows novice houseplant owners exactly how to keep indoor plants alive and healthy. Gardening expert Ellen Zachos helps you choose the right plants in the first place and then shows you how to care for them, outlining what each kind needs in terms of location, sunlight, water, and fertilizer. She also explains when plants should be repotted (and how to do that successfully), how and when to prune them, how to keep them clean of dust and pets, and more. This Storey BasicsÂ® guide has all the information you need to keep any houseplant thriving and beautiful!
Sabrina is a firebird blazing through 1950s New York: she is a woman daring to enjoy the sexual licence that men have always known. Weaving a sensual web of deceit as she plays dangerous games of desire, she deliberately avoids commitment, gripped by the pursuit of pleasure for its own sake.
Forces of nature and human intervention lead to innumerable local, regional and sometimes global changes in plant community patterns. Irrespective of the causes and the intensity of change, ecosystems are often naturally able to recover most of their attributes through natural succession. In this thoughtful and provocative new book, Fakhri Bazzaz integrates and synthesises information on how disturbance changes the environment, how species function, coexist, and share or compete for resources in populations and communities, and how species replace each other over successional time. Furthermore, the book shows how a diverse array of plant species have been used to examine fundamental questions in plant ecology by integrating physiological, population and community ecology. Graduate students and research workers in plant ecology, global change, conservation and restoration will find the perspective and analysis offered by this book an exciting contribution to the development of our understanding of plant successional change.
