This book brings out the structural and functional aspects of plants and animals at different stages of their life cycle. The content included in the papers is contributed by different authors; it is mostly original and supplemented by the works of other workers published in India and elsewhere. The contributions include phenological and ecological aspects of reproduction in tree taxa in the scrub vegetation, reproductive ecology of Acacia farnesiana, A. sinuata and Semecarpus anacardium, Rauvolfia tetraphylla, R. micrantha, ornithophily, ornithochory, wasp-flower relationships in sustaining biodiversity, conservation status of chelonian fauna, information about thelypteroid ferns, marine woodborer fauna, floristics and ethnobotany of mangroves, bee flora, honeybee pollination in Matricaria chamomilla, Cucurbita pepo, Luffa acutangula, enhancing the seed yield of sunflower, biochemical profiles of floral rewards for honeybees, importance of organic farming for sustainable agriculture, inventorization and prioritization of wetlands of Orissa using remote sensing and GIS, biodiversity assessment and spatial modeling for biological richness analysis, etc. All these aspects were discussed at length. The information provided is of prime importance for the conservation and management of ecological interactions taking place at different stages of plant and animal life. The information provided on mangroves is a good contribution to the existing knowledge on mangroves of India. The information on ornithophily and ornithochory in the plants of Eastern Ghats is highly useful for taking steps for the effective conservation of habitats and at the same time for the promotion of ecotourism prospects.The reproductive biology information on certain plants in the Eastern Ghats is highly valuable for understanding the relationships between plants and insects at flowering stage. Honey bee flora for certain areas and honey bees role in enhancing pollination and seed production rate were also well explained for consideration in bee-keeping practices. Further, this book also provides certain important information about biodiversity assessment using remote sensing and geographical information systems. Therefore, this book is a collection of information on different aspects of plants and animals at species level, ecosystem level and finally the interactions between them for sustaining biodiversity. This book is an important dictionary for those working in the subjects of conservation biology of terrestrial and mangrove forests and apiculture; in ornithology and remote sensing and geographical information systems.
