Book Description
This text summarizes the results of studies on the pollination ecology of the unique family Compositae (Asteraceae). The complex structural and functional specializations of the capitulum (or head) for pollinator attraction and pollen transfer are described in detail. An attempt is made to identify the influence of these specializations on the development and the function of other floral parts. The remarkable sex polymorphism of the Compositae head, which has caused much confusion amongst students is traced to this influence and characterized as a secondary modification. The central concept in the book is taht pollination ecology is the guiding factor in Compositae evolution.

Book Description
"This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

Book Description
Nectar is the most important reward offered by plants to pollinating animals. This book is a modern and interdisciplinary text on nectar and nectaries, prompted by the expansion of knowledge in ecological and molecular fields, and the strong recent interest in pollination biology. The topics covered vary widely: they include historical aspects, the structure and ultrastructure of nectaries and relationships to plant systematics, the dynamics of nectar secretion, nectar chemistry and the molecular biology of defence proteins, and more.

Book Description
Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.

Book Description
Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Book Description
A wide-ranging study that draws on local and regional research findings to provide a popular portrait of the biodiverse and resilient Chiquibul. Belize’s Chiquibul Forest is one of the largest remaining expanses of tropical moist forest in Central America. It forms part of what is popularly known as the Maya Forest. Battered by hurricanes over millions of years, occupied by the Maya for thousands of years, and logged for hundreds of years, this ecosystem has demonstrated its remarkable ecological resilience through its continued existence into the twenty-first century. Despite its history of disturbance, or maybe in part because of it, the Maya Forest is ranked as an important regional biodiversity hot spot and provides some of the last regional habitats for endangered species such as the jaguar, the scarlet macaw, Baird’s tapir, and Morelet’s crocodile. A Natural History of Belize presents for the first time a detailed portrait of the habitats, biodiversity, and ecology of the Maya Forest, and Belize more broadly, in a format accessible to a popular audience. It is based in part on the research findings of scientists studying at Las Cuevas Research Station in the Chiquibul Forest. The book is unique in demystifying many of the big scientific debates related to rainforests. These include “Why are tropical forests so diverse?”; “How do flora and fauna evolve?”; and “How do species interact?” By focusing on the ecotourism paradise of Belize, this book illustrates how science has solved some of the riddles that once perplexed the likes of Charles Darwin, and also shows how it can assist us in managing our planet and forest resources wisely in the future.

Book Description
Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Book Description
The book covers many areas of Medicinal plants research including traditional and scientific research that boost extensional activities in India and abroad. Many plants incorporated in India but many years the traditional use practice is going on so these are important tools to use the components in herbal therapy. People use traditionally as well as mixed preparations to share their knowledge. In industry, many components have ben widely used to prepare medicines that is economic. In addition to the applied aspects it boosts ecological value because of the wide use of components as living parts or the products in India and abroad. The articles would convey the message for long term use and wide preservation techniques to conserve the species in a global basis.

Book Description
Now that so many ecosystems face rapid and major environmental change, the ability of species to respond to these changes by dispersing or moving between different patches of habitat can be crucial to ensuring their survival. Understanding dispersal has become key to understanding how populations may persist. Dispersal Ecology and Evolution provides a timely and wide-ranging overview of the fast expanding field of dispersal ecology, incorporating the very latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species, and community levels are considered. Perspectives and insights are offered from the fields of evolution, behavioural ecology, conservation biology, and genetics. Throughout the book theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible - both plant and animal.
