Principles of Dispersal in Higher Plants by L. van der Pijl Pdf

Reviewers from diverse branches of botany have exerted pressure to have chapters dealing with their field extended. If only to cover his incompetence, the author could not accede to these requests. Nor was it possible to respond to Eastern European urgings to extend the classificatory terminology, especially in ChapterX. He is grateful for indications of factual shortcomings in the chosen field, especially for those by Dr. RUDOLF SCHMID (Ann Arbor), who provided exten sive comment. L. VAN DER PIlL The Hague, spring 1972 Preface to the First Edition The work offered here is a companion volume to the work by K. FAEGRI and 1. VAN DER PIJL, Principles of Pollination Ecology, whim. deals with the preced ing phase of reproduction in plants. In the present work too, the emphasis is on principles and ecology. It is neither an enumeration of mechanisms, nor a compilation of cases. RIDLEY'S monumental work The Dispersal of Plants Throughout the World comprises 700 large pages of small print, and research has proceeded since then. Though this work is more than just a compilation and contains much insight and thoughts on principles in addition to reviews, its completeness hinders its use as a text book. As a reference work, it is unsurpassed and the writer made frequent use of it. The writer paid special attention to functional backgrounds for the use of taxonomists working with "characters" and to biosystematics at the macro-level.

Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.

Embryology of Flowering Plants: Terminology and Concepts, Vol. 3 by T B Batygina Pdf

Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.

Nouragues by F. Bongers,P. Charles-Dominique,P.-M. Forget,Marc Théry Pdf

Nouragues is a tropical forest research station in French Guiana. It was established in 1986 for research on natural mechanisms of forest regeneration. Since then a lot of research has been done on this and related topics. This book provides an overview of the main research results, and focuses on plant communities, vertebrate communities and evolutionary ecology, frugivory and seed dispersal, and forest dynamics and recruitment. The appendices give (annoted) checklists of plants, birds, mammals, herpetofauna and fishes found in the same area.

Flowering Plants by K. Kubitzki Pdf

The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented.

The Eco-physiological and Genetic Basis of Invasiveness by Gowher A. Wani,Manzoor A. Shah Pdf

The invasion of ecosystems by alien species is a key driver of global environmental change and many invasive plant species attain sufficiently high abundance to alter the structure and function of an ecosystem. This book is the first publication to explain the reasons as to why some alien species undergo a profound shift in their ecological fortune from being minor components of their native ecosystems to becoming devastating dominants of non-native habitats. The book assesses the ecological, morphological, functional and genetic factors that contribute to invasion success. Cutting-edge tools in molecular genetics in the past two decades have opened up additional avenues for ecologists to address such questions and obtain novel insights in the ecology of invasive species. This text also highlights which molecular approaches are especially useful in discriminating between native and non-native populations of invaders that cannot otherwise be differentiated based on morphological traits. Such molecular approaches can yield useful insights with potential implications for biodiversity managers to identify alien invasive species that are likely to become invaders in the near future, thereby prioritizing them accordingly for different management strategies.

Mutualistic Interactions between Flowering Plants and Animals by Palatty Allesh Sinu,KR Shivanna Pdf

The plant-animal interactions, both mutualistic and antagonistic, play a crucial role in the diversification of plants and animals, and are important in functioning of communities in their natural habitats. The mutual interactions between the flowering plants and the animals, in pollination and seed dispersal, largely determine the reproductive success of the flowering plants. Maintenence of these eco-services is critical for the sustainability of our biodiversity. India,with its rich biodiversity and leveling of crop yields in recent years would benefit from research in the area of plant-animal interactions. This volume includes chapters on various aspects of mutualistic plant-animal interactions. In particular the fundamental and applied aspects of ecoservices – pollination and seed dispersal are covered comprehensively. It also covers tritrophic interaction and the potential of genomics in studies on the plant-animal interactions. The book will be of interest to post-graduate students, teachers and researchers in the areas of Biology, Ecology, Botany, Zoology, Agri-horticulture, Forestry, and Conservation Biology.

High Diversity Forest Restoration in Degraded Areas by Ricardo Ribeiro Rodrigues Pdf

The discussion of ideas, methods, scientific results, empirical practices and perspectives on the restoration of high diversity tropical and subtropical forest formations is the objective of this book; however, principles here proposed may be used in other less complex forest formations. Special attention is given to the role of the ecological processes on the restoration of functional forest communities, once the composition and structure of these natural or even restored communities change in space and time.
