Cercidiphyllum is a relict angiosperm bringing to us a flavor of Cretaceous Period. Its reproductive morphology was interpreted, in the spirit of the dominant evolutionary paradigm, as inflorescences of reduced flowers represented by solitary pistils and groups of stamens. Evolutionary significance of Cercidiphyllum has long been anticipated despite the unpersuasive morphological interpretation and irrelevant paleobotanical evidence. This work was initially intended for paleobotanists who willingly compare their fossil material with the living Cercidiphyllum, using schematic descriptions and illustrations of traditional plant morphology. The idea behind this book was to provide an adequately illustrated material for such comparisons. Yet it turned out that there are more things in Cercidiphyllum than are dreamed of in our traditional plant morphology. Some of morphological findings of this study, such as the replacement of the floral structure by leafy shoots or the subtending bract-leaf conversion are relevant to the experimental "evo-devo" studies and bear on general problems of angiosperm evolution. In Cercidiphyllum, the vegetative body is partly or mostly produced in the reproductive line, suggesting a neotenic ancestral form, in which the vegetative development was drastically reduced relative to reproductive domain. Later in evolutionary history, the vegetative body was rebuilt in the lineage on the way to arboreal forms, with foliation of the floral receptacles and the carpel-leaf convergence as side effects of the process.

This taxonomic review of the Cuban Miridae (Hemiptera: Heteroptera) treats 105 species in 57 genera. Twelve new species are described, two new synonyms are recognized, and four previously recorded species are removed from the list. All genera and species are diagnosed, and a thorough literature review and information on host plants and distribution are given. Male genitalia are illustrated and a color image is provided for nearly all species. Identification keys to subfamilies, tribes, genera, and species are included, and the biogeography of the Cuban and West Indian mirid fauna is discussed. This work will form a solid foundation for future research on the plant bugs of Cuba, providing a summary of the information known about each species and the means to accurately identify them.

Tall buildings dominate the landscape of most major cities, and crowds stare in awe of masterpieces in museums around the world. But how is science involved?Art and Architecture explores some of the scientific principles in sculpture, painting, photography, and the design and construction of buildings. Learn how light creates the colors you see in a painting and how holograms are produced. Discover the history of architecture from the ancient stone pyramids of Egypt to modern structures made from glass and steel. Hands-on activities help bring the science of art and architecture to life with topics ranging from how the forces of tension and compression affect the design of a bridge to how perspective in a drawing can make a picture look more lifelike.

The Australian bustard is Australia’s heaviest flying bird. It is an icon of the Australian outback where it is more commonly known as the bush or plains turkey. It is also culturally and spiritually significant to Aboriginal people, who prize it as a favorite bush tucker. This book provides the first complete overview of the biology of the Australian bustard. Based on the first major study of the species, the author explores the bustard’s ecology and behavior, its drastic decline since European settlement, and the conservation issues affecting it and its environment. Color photographs of juvenile and adult birds complement the text as well as showcase particular behaviors, such as the spectacular display routines of males when mating, which are unique among Australian birds. Australian Bustard is the perfect book for natural history enthusiasts.

Several different databases and models have been developed over many years of petrological study carried out by several European and non-European groups on mantle xenoliths, peridotite massifs, ophiolites and mafic magmas spanning in age from Archaean to Recent times. This volume aims to bring together these different approaches and to integrate the geochemical perceptions of the European upper mantle. The papers include regional petrological studies of the European lithospheric mantle, from Spain to the Pannonian Basin, from Corsica and Serbia as far north as Svalbard. Six contributions are based on studies of mantle xenoliths, while the remaining three deal with ophiolitic and peridotitic complexes. A further article provides an update on the textural classification of mantle rocks using a computer-aided approach and there is an introductory overview.

This book provides the analysis of a uniquely large, population-based data set evaluating congenital anomalies as a consequence of maternal diseases. The possible adverse birth outcomes of babies born to mothers diagnosed with important diseases have not yet been evaluated in such a material by the same method. The greatest merit of these studies is that by analyzing their data the authors managed to identify some new previously unknown associations between maternal diseases and adverse birth outcomes. The first aim of the authors was to summarize 50 years of experiences in human teratology which may help younger experts to use them. The second objective was to show the methodological weaknesses of previous studies and to recommend the use of up-to-date methods when designing new studies. A surveillance database like the one used in these studies effectively helps to monitor the most important indicators of adverse birth outcomes such as congenital anomalies, preterm births, and low birth weight, to evaluate the efficacy of medical care of pregnant women, and to detect possible causes of adverse birth outcomes in order to help in their prevention. In addition, the analysis of cost-benefit of this database showed that the benefit is much higher than cost. This book may be useful in the daily practice for obstetricians, paediatricians, general practitioners and epidemiologists, moreover it could be used in the training programmes of medical students and residents as well.
