Book Description
For biologists, 2009 was an epochal year: the bicentennial of Charles Darwin’s birth and the 150th anniversary of the publication of a book now known simply as The Origin of Species. But for many botanists, Darwin’s true legacy starts with the 1862 publication of another volume: On the Various Contrivances by Which British and Foreign Orchids Are Fertilised by Insects and on the Good Effects of Intercrossing, or Fertilisation of Orchids. This slim but detailed book with the improbably long title was the first in a series of plant studies by Darwin that continues to serve as a global exemplar in the field of evolutionary botany. In Darwin’s Orchids, an international group of orchid biologists unites to celebrate and explore the continuum that stretches from Darwin’s groundbreaking orchid research to that of today. Mirroring the structure of Fertilisation of Orchids, Darwin’s Orchids investigates flowers from Darwin’s home in England, through the southern hemisphere, and on to North America and China as it seeks to address a set of questions first put forward by Darwin himself: What pollinates this particular type of orchid? How does its pollination mechanism work? Will an orchid self-pollinate or is an insect or other animal vector required? And how has this orchid’s lineage changed over time? Diverse in their colors, forms, aromas, and pollination schemes, orchids have long been considered ideal models for the study of plant evolution and conservation. Looking to the past, present, and future of botany, Darwin’s Orchids will be a vital addition to this tradition.

Book Description
This book's aim is to obtain and organize knowledge about the diversity of living things. Their epistomological and methodological fundamentals are explained in the framework of the biology of evolution. The methods of construction and use of phylogenetic trees are presented as well as the classification and description of taxa with the nomenclature rules.

Book Description
`The fundamental problem the world faces today, is the rapidly increasing pressure of population on the limited resources of the land. To meet the ever increasing demands of expanding populations, agricultural production has been raised through the abundant use of inorganic fertilizers, the adoption of multicropping systems and liberal application of chemical pesticides (fungicides, bactericides, etc. ). Though the use of chemicals has increased the yield dramatically, it has also resulted in the rapid deterioration of land and water resources apart from wastage of scarce resources. This has adversely affected the biological balance and lead to the presence of toxic residues in food, soil and water in addition to imposing economic constraints on developing countries.' (From the Preface) Mycorrhizal Biology addresses the global problem of land degradation and the associated loss of soil productivity and decline in soil quality caused by exploitative farming practices and poor management in developing countries, and the far reaching socio-economic and ecological consequences of its impact on agricultural productivity and the environment. In the light of a need for sustainable development, a new system of productive agriculture, to ensure the efficient management of agricultural inputs for long term high crop productivity with minimum damage to the ecological and socio-economic environment is essential. The management of mycorrhizal fungi will form a significant part of such a system and this work investigates the key association of plant roots with mycorrhizal fungi, known to benefit plants under conditions of nutritional and water stress and pathogen challenge and analyses the developments in our understanding of the genetic loci that govern mycorrhiza formation.

Book Description
This work follows on from the 1995 publication on European orchids. The atlas is now completed with a second part, containing data on the pollination of orchids of the continents of America, Asia, Africa (including Madagascar) and Australia (including New Zealand).;The first part of the book is adapted from the general account of the previous publication and is extended with chapters on taxonomy and pollinators. The general account deals with such things as the history, evolution, morphology, chemistry and genetics of orchid pollination. The second part gives a systematic account for each continent of all well known details. The text is designed to have relevance for orchid lovers whether professional or amateur.
