Book Description
The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Book Description
This book focuses on the taxonomic diversity of the genus Tuber as economically important truffles. In contributions by internationally respected scientists, it examines truffle systematics, interactions with abiotic and biotic environments, strategies for spore dispersal, and molecular processes in truffles. Topics discussed include: evolutionary theories and phylogeny of Tuber species from Asia, Europe and North-America; the influence of climate on the natural distribution of Tuber species and fruiting body production, soil characteristics and vegetation in natural habitats; tools for tracing truffles in soil, host diversity, truffle inhabiting fungi and truffle-associated bacteria; and the relationships of small mammals and wild boars with truffles, as well as the smell of truffles.This book offers a valuable reference guide for all researchers working in the fields of mycology, ecology and the soil sciences, and will also be useful for farmers and foresters interested in truffle cultivation worldwide.

Book Description
The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Book Description
SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Book Description
The OPD Second Canadian Edition is an illustrated, theme-based dictionary for second-language learners. This four-colour dictionary defines words through pictures, and presents each new word in context. The OPD, along with its workbooks and many other components, can be used as a referencebook or as text for high school or adult ESL students at the beginner level.For years, the first Canadian edition of the OPD has been the industry leader among picture dictionaries. The second edition expands on the topics covered, providing more depth of vocabulary in the areas that matter most to students. The illustrations have been completely updated in a more realisticstyle that is visually appealing to adult learners.The second edition also contains two new features: Introductory Pages and Story Pages. The Introductory Pages have been added to the beginning of each theme to give lower-level students a basic overview of key vocabulary words, and to give a starting point for discussion and an introduction to thetheme for more advanced students. The Story Pages consist of a two-page spread at the end of each theme to help students use the words in context and practise their reading skills.The OPD is designed for use both in and out of the classroom. Speaking exercises are presented throughout the OPD to allow students to practise new vocabulary in pairs or small groups, while the pronunciation guide in the index allows students to check their pronunciation when they are studying ontheir own.
