Book Description
From the machair grasslands of the Outer Hebrides to the chalk cliffs of Kent, and from the dense pinewoods of Abernethy forest to the wetlands of the Fens of eastern England, Britain offers a richly varied array of habitats for our wild flowers. The distinguished science and natural history producer and filmmaker Steve Nicholls presents a visually stunning survey of Britain's best-loved wildflowers, illustrated with the his own beautiful photographs of flora in their habitat. Focusing on three broad habitats – grassland, open land and woodland – he offers a biologically rigorous but engagingly readable account of our wild flowers and the places that nourish them. He probes deep into the social and cultural history of wild flowers to tell a plethora of fascinating stories, from the 'daffodil trains' which transported Londoners to the 'golden triangle' in Gloucestershire to experience woodlands carpeted with wild daffodils, to the odd case of the Bath asparagus – which isn't an asparagus at all, but rather the edible flower buds of the rare spiked star of Bethlehem, which used to grow in abundance around Bath.

Book Description
This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.

Book Description
Why do males and females frequently differ so markedly in body size and morphology?lSex, Size, and Gender Roles is the first book to investigate the genetic, developmental, and physiological basis of sexual size dimorphism found within and among the major taxonomic groups of animals. Carefully edited by a team of world-renowned specialists in the field to ensure a coherence of style and approach between chapters, it presents a compendium of studies into the evolution, adaptive significance, and developmental basis of gender differences in body size and morphology. Adaptive hypotheses allude to gender-specific reproductive roles and associated differences in trophic ecologies, life history strategies, and sexual selection. This "adaptationist" approach is balanced by more mechanistic studies of the genetic, developmental and physiological basis of sexual size dimorphism to provide a comprehensive and authoritative overview of the subject. Throughout the volume the emphasis is on sexual dimorphism in overall size; however, the scope of enquiry encompasses gender differences in body shape, the size and structure of secondary sexual characteristics, patterns of growth (ontogeny), and patterns of gene regulation. This advanced, research level text is suitable for graduate level students and researchers in the fields of evolutionary biology, behavioural ecology, physiology, developmental biology, and genetics. It will also be of relevance and use to non-biologists from fields such as anthropology and gender studies.

Book Description
Sexual Dimorphism- Various biological studies on the subject of sex differences have been published. The subjects of these studies are not only humans, but also other mammals, birds, amphibians, insects, extending to ostracoda in the Paleozoic era. Moreover, original methods in individual studies have been used. This book provides convincing reasons which explain sex differences. The book also shows that, even if considered that some living things do not have sex differences, in reality they do. The somewhat different data on sex differences in this book will offer new ideas not only to life scientists and biologists, but social and cultural scientists as well.
