Book Description
The genus Ophrys constitutes one of the most diverse and biologically fascinating groups of plants to be encountered in Europe, particularly the Mediterranean.This book offers an easy to use, comprehensive, introduction to the genus, throughout its European range, It can be used as a field guide, with keys, descriptions and numerous colour photographs, as well as a standard reference, with chapters on structure, biology, evoltuion and conservation. The classification is based on a broad species concept, offering an alternative to the finely split classifications of the genus that prevail in most recent field guides. Notes on hardy orchid cultivation, by Richard L. Manuel, and a chapter of ideas for field trips, complete the picture.

Book Description
Molecular Systematics and Plant Evolution discusses the diversity and evolution of plants with a molecular approach. It looks at population genetics, phylogeny (history of evolution) and developmental genetics, to provide a framework from which to understand evolutionary patterns and relationships amongst plants. The international panel of contributors are all respected systematists and evolutionary biologists, who have brought together a wide range of topics from the forefront of research while keeping the text accessible to students. It has been written for senior undergraduates, postgraduates and researchers in the fields of botany, systematics, population / conservation genetics, phylogenetics and evolutionary biology.

Book Description
Le petit Ophrys n'est pas un dictionnaire comme les autres : C'est un dictionnaire anglais-français, format de poche, conçu pour les lecteurs d'aujourd'hui. Il a éliminé les mots faciles, évidents, connus de tous, transparents pour les francophones, que personne ne cherche jamais dans un dictionnaire. La place ainsi gagnée a permis de donner Tous les sens d'un mot et d'ajouter un nombre appréciable de termes écossais, irlandais, yiddish, australiens, etc, bloquant souvent la compréhension. Il contient tous les mots indispensables pour Comprendre aussi bien un roman anglais du dix-huitième siècle qu'un roman policier américain ; un article de la presse politique ou économique, juridique ou technique ; les émissions de radio où abondent les verbes composés (phrasal verbs) et les expressions idiomatiques. D'une grande clarté, d'un grand confort de lecture, ce dictionnaire, important par le contenu, petit dans sa forme, permet de bien comprendre, vite, en tout lieu, à tout instant.

Par rapport à la version précédente, elle propose un texte révisé ; de nouveaux exercices en deux niveaux : niveau 1 consolidation des bases, révision (classes de seconde), niveau 2 approfondissement (classes de première et terminale). Un exercice sur deux est en auto-corrigé : pour une plus grande autonomie de l'élève et un travail préparatoire aux exercices non-corrigés. Les exercices non-corrigés peuvent être faits sous la direction du professeur ou proposés dans le cadre d'une évaluation. Les points de grammaires sont abordés sur la page de gauche. Description et mise en relation des faits de langue, comparaison d'énoncés, paraphrases et transformations. Mais aussi afin de fixer les connaissances, tableaux récapitulatifs, listes (verbes d'état, verbes suivis du gérondif ou de l'infinitif, verbes prépositionnels, noms indénombrables, etc.) Les exercices se trouvent sur la page de droite. Tableaux de classement et d'analyse d'énoncés pour une meilleure compréhension de la valeur des formes, manipulations, réécriture, transformation d'énoncés pour la fixation des formes grammaticales, textes à compléter (avec notes de vocabulaire), questions à choix multiples, thème grammatical. Un index des difficultés repérées par le mot-clé est donné en fin d'ouvrage. Les termes d'origine linguistique sont présentés de façon simple dans un glossaire. Les corrigés des exercices sont également donnés en fin d'ouvrage. Les exercices qui ne sont pas en auto-corrigé dans l'ouvrage sont présentés corrigés dans un livret annexe.

Book Description
South Cambridgeshire has some of the richest arable land in England and has been cultivated for millennia. By the turn of the nineteenth century industrialisation and massive population growth had resulted in an enormous increase in the demand for food, which in turn led to enclosure. But this desire to plough every available piece of land resulted in the destruction of many valuable and distinctive habitats that had existed for centuries. The Ecology of Enclosure breaks new ground in comparing the effect of Parliamentary Enclosure with the findings of the enthusiastic 'Botanisers' from Cambridge; this reveals not only the effect of enclosure on the ecology of the land but also on the people whose link with the land was broken. The first section presents a study of social and agricultural life before enclosure, describing geology and climate; the fold-course open field system of farming and the strict stinting rules which governed how land could be used for grazing and stock movement; and the crop rotation systems employed. The second part describes the process of enclosure, including opposition to it; the changes that occurred to the landscape and within village communities as work in industry gradually replaced rural occupations; the effects of fencing on movement; and of the loss of common land to the plough. The third section is an analysis of the new study of Botany which the University of Cambridge was enjoying in the eighteenth and nineteenth centuries based on their own records and a review of some of the specific effects on the flora and fauna of the area.
