The edited volume deals with the origin, evolution, genetic diversity, commercial, and cultural aspects of selected tree species such as Rubber, Pine, Poplar, Almond, Cashew, Teak, Olive, Eucalyptus, Mango, Jack, Fig, Sandalwood and Ashoka. It covers major aspects of the altered gene pool of each tree species, its impact on biodiversity, the current scenario, and the strategies to protect and conserve the wild progenitors of these trees.

R-Trees Theory and Applications

Nowadays, a significant number of applications require the organization of data elements which contain at least one spatial attribute. Space support in databases poses new challenges in every part of a database management system and the capability of spatial support in the physical layer is considered very important. This has led to the design of spatial access methods to enable the effective and efficient management of spatial objects.R-trees have a simplicity of structure and, together with their resemblance to the B-tree, allow developers to incorporate them easily into existing database management systems for the support of spatial query processing.This book provides an extensive survey of the R-tree evolution, studying the applicability of the structure and its variations to efficient query processing, accurate proposed cost models, and implementation issues like concurrency control and parallelism. Based on the observation that “space is everywhere", the authors anticipate that we are in the beginning of the era of the “ubiquitous R-tree" analogous to the way B-trees were considered 25 years ago. Written for database researchers, designers and programmers as well as graduate students, this comprehensive monograph will be a welcome addition to the field.The book successfully integrates research results of the last 20 years, in a clear and highly readable manner. It is the first book dedicated to R-trees and related access methods, and I believe it will be valuable as a reference to everyone interested in the area.Prof. Timos Sellis, National Technical University of Athens

Long, long ago, in a land far away, lived a perfect little tree named Small Pine. Small Pine hoped to maintain its perfect form and be selected by the Queen as her Christmas tree. But as the warm-hearted little tree gave shelter to birds, rabbits, and deer in the forest, its branches became damaged. Fortunately, the Queen had a different idea of perfection…

Major Flowering Trees of Tropical Gardens


Free Download M. S. Swaminathan, "Major Flowering Trees of Tropical Gardens"
English | ISBN: 1108481957 | 2019 | 416 pages | PDF | 130 MB
This comprehensive text on flowering trees of tropical gardens discusses some new species of trees, including Adansonia digitata, Monodora myristica, Flacourtia montana, Balanites aegyptiaca, Bursera serrata, Commiphora wightii and Semecarpus anacardium. The text covers more than 200 of the most striking and widespread trees alongside closely related genera and species (both native and exotic) commonly encountered in the tropical climate. It includes more than 700 high resolution coloured photographs, depicting different facets including growth habit, morphological details of stem, leaves, flowers and fruits. The different tree species are organized according to Bentham and Hooker’s system of classification of seed plants. The book discusses many aspects of trees including common and botanical names together with synonyms, taxonomic families, etymology (how trees have derived their names), phenology, their native place, geographical distribution, mythological notes, religious significance and economic importance. The text is useful for graduate students and academic researchers in the field of life sciences.
