"Lime trees (Tilia spp.) are widely distributed and locally important members of northern temperate broad-leaved forests. In marked contrast to the largely uniform morphology of the genus its taxonomic treatment has become increasingly confused and controversial, with over one hundred species and numerous subspecies described. Using extensive data from field studies of natural populations around the world, this book clarifies the situation, proposing a revised taxonomy of 23 species and 14 subspecies. Detailed descriptions are provided for all recognised taxa and are accompanied by illustrations. Data from herbaria and cultivated trees are used to extend the analyses where appropriate and type specimens are included to stabilise nomenclature. Lime tree ecology is also considered, with an exploration of experimental and analytical data on regeneration, growth and reproduction in relation to climate and soils. Additional material includes a glossary of botanical terms and appendices of herbarium codes and relevant physical concepts"-- "Tilia is the type genus of the family name Tiliaceae Juss. (1789), and T. x europaea L. the type of the generic name (Jarvis et al. 1993). Members of Tiliaceae have many morphological characters in common with those of Malvaceae Juss. (1789) and both families were placed in the order Malvales by Engler (1912). In Engler's treatment, Tiliaceae consisted mainly of trees and shrubs belonging to several genera, including a few herbaceous genera, almost all occurring in the warmer regions. This treatment was revised by Engler and Diels (1936). The family was retained by Cronquist (1981) and consisted of about 50 genera and 700 species distributed in the tropics and warmer parts of the temperate zones in Asia, Africa, southern Europe and America. Several genera of trees, such as Apeiba in South America and Tilia itself, are of economic value for timber, and similarly the herbaceous genus, Corchorus, includes C. olitorius which is grown extensively in Bengal as the source of a brown fibre, jute, used for string, cloth ('hessian'), formerly carpet-backing and paper"--

Plant secondary metabolism is an economically important source of fine chemicals, such as drugs, insecticides, dyes, flavours, and fragrances. Moreover, important traits of plants such as taste, flavour, smell, colour, or resistance against pests and diseases are also related to secondary metabolites. The genetic modification of plants is feasible nowadays. What does the possibility of engineering plant secondary metabolite pathways mean? In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways. In a series of chapters from various authorities in the field, an overview is given of the state of the art for important groups of secondary metabolites. No books have been published on this topic so far. This book will thus be a unique source of information for all those involved with plants as chemical factories of fine chemicals and those involved with the quality of food and ornamental plants. It will be useful in teaching graduate courses in the field of metabolic engineering in plants.

"Biological development, how organisms acquire their form, is one of the great frontiers in science. While a vast knowledge of the molecules involved in development has been gained in recent decades, big questions remain on the molecular organization and physics that shape cells, tissues and organisms. Physical scientists and biologists traditionally have very different backgrounds and perspectives, yet some of the fundamental questions in developmental biology will only be answered by combining expertise from a range of disciplines. This book is a personal account by Professor Lionel Harrison of an interdisciplinary approach to studying biological pattern formation. It articulates the power of studying dynamics in development: that to understand how an organism is made we must not only know the structure of its molecules; we must also understand how they interact and how fast they do so"--

Describes the remarkable world of birds and their multitude of behaviours.Why do pigeons bob their heads when they walk? Can talking parrots understand what they say? What do birds learn and remember?Birds is an unusual collection of curious facts about our feathered friends. It describes the fascinating behaviours and physiology of birds of all shapes and sizes - from the birds in our cities to the wild birds in rainforests and at sea shores, in deserts and plains. You'll learn how birds evolved and why some came to be flightless. You'll read of the wide diversity in bird courtship rituals and territorial displays. You'll discover the art of nest building and why some birds have such well-developed senses and memory. In short, Birds explains why these creatures do the things that they do, so you can more fully enjoy and understand the birds you see every day.Gisela Kaplan and Lesley Rogers, two leading researchers in animal behaviour, cover the latest findings in bird behaviour and tell stories of their personal encounters with birds throughout the world, collected in more than twenty years of research. Supplemented with arresting photographs, this is a marvellous companion for the curious birdwatcher, the serious student of biology and for any nature or bird lover.
