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!
What Christmas Is as We Grow Older and Thoughts about people are short stories by Charles Dickens. Charles John Huffam Dickens (7 February 1812 - 9 June 1870) was an English writer and social critic. He created some of the world's most memorable fictional characters and is generally regarded as the greatest novelist of the Victorian period. During his life, his works enjoyed unprecedented fame, and by the twentieth century his literary genius was broadly acknowledged by critics and scholars. His novels and short stories continue to be widely popular. Born in Portsmouth, England, Dickens was forced to leave school to work in a factory when his father was thrown into debtors' prison. Although he had little formal education, his early impoverishment drove him to succeed. Over his career he edited a weekly journal for 20 years, wrote 15 novels, five novellas and hundreds of short stories and non-fiction articles, lectured and performed extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, education, and other social reforms. Dickens sprang to fame with the 1836 serial publication of The Pickwick Papers. Within a few years he had become an international literary celebrity, famous for his humour, satire, and keen observation of character and society. His novels, most published in monthly or weekly installments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. The installment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her disabilities, Dickens went on to improve the character with positive features. Fagin in Oliver Twist apparently mirrors the famous fence Ikey Solomon; His caricature of Leigh Hunt in the figure of Mr Skimpole in Bleak House was likewise toned down on advice from some of his friends, as they read episodes. In the same novel, both Lawrence Boythorne and Mooney the beadle are drawn from real life-Boythorne from Walter Savage Landor and Mooney from 'Looney', a beadle at Salisbury Square. His plots were carefully constructed, and Dickens often wove in elements from topical events into his narratives. Masses of the illiterate poor chipped in ha'pennies to have each new monthly episode read to them, opening up and inspiring a new class of readers.
