The native British flora is today relatively ant species on the continent, such as Picea impoverished. Today the British Isles has a abies (Norway spruce), did not get into Britain flora of only about 1500 species of native in time. However, we must not over flowering plants. France and Spain, each emphasize the importance of Britain being an geographically only about twice the area, island. A comparison of floras on either side have 3-4 times as many species each. The of the English Channel shows that there are comparison is more marked when consider species present in England and not in ing the endemic species, those specialities of northern France as well as vice versa. Many each geographical region which grow of the species present in northern France but nowhere else. If only normal sexual species absent from England are weeds adapted to are considered, then there are only about 13 French agriculture. Others may be limited endemic species in the British Isles while 1000 not by the sea but by the climate. species are endemic to Spain. Nevertheless, the example of Ireland, However, the poverty of the British flora is which was isolated much earlier than the rest not a unique phenomenon. The whole of of the British Isles, does show the effect of north-western Europe, an area including isolation because it does have a much poorer northern France and much of Germany and flora and fauna.
This book is a translation of a unique Russian study of fossil plant distributions in the Jurassic and Cretaceous world.
Often regarded as the 'Cinderella' of palaeontological studies, palaeobotany has a history that contains some fascinating insights into scientific endeavour, especially by palaeontologists who were perusing a personal interest rather than a career. The problems of maintaining research facilities in universities, especially in the modern era, are described and reveal a noticeable absence of a national UK strategy to preserve centres of excellence in an avowedly specialist area. Accounts of some of the pioneers demonstrate the importance of collaboration between taxonomists and illustrators. The importance of palaeobotany in the rise of geoconservation is outlined, as well as the significant and influential role of women in the discipline. Although this volume has a predominantly UK focus, two very interesting studies outline the history of palaeobotanical work in Argentina and China.
Plants in Mesozoic Time showcases the latest research of broad botanical and paleontological interest from the world's experts on Mesozoic plant life. Each chapter covers a special aspect of a particular plant group -- ranging from horsetails to ginkgophytes, from cycads to conifers -- and relates it to key innovations in structure, phylogenetic relationships, the Mesozoic flora, or to animals such as plant-eating dinosaurs. The book's geographic scope ranges from Antarctica and Argentina to the western interior of North America, with studies on the reconstruction of the Late Jurassic vegetation of the Morrison Formation and on fossil angiosperm lianas from Late Cretaceous deposits in Utah and New Mexico. The volume also includes cutting-edge studies on the evolutionary developmental biology ("evo-devo") of Mesozoic forests, the phylogenetic analysis of the still enigmatic bennettitaleans, and the genetic developmental controls of the oldest flowers in the fossil record.
New Organic Architecture is a manifesto for building in a way that is both aesthetically pleasing and kinder to the environment. It illuminates key themes of organic architects, their sources of inspiration, the roots and concepts behind the style, and the environmental challenges to be met. The organic approach to architecture has an illustrious history, from Celtic design, Art Nouveau, Arts and Crafts, to the work of Antoni Gaud� and Frank Lloyd Wright. Today there is a response to a new age of information and ecology; architects are seeking to change the relationship between buildings and the natural environment. In the first part of his book, David Pearson provides a history and assessment of organic architecture. The second part comprises statements from thirty architects from around the world whose work is based on natural or curvilinear forms rather than the straight-line geometrics of modernism. Each statement is accompanied by full-color illustrations of one or several of the architects' built projects.
The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.
