Successful reproduction is the basis not only for the stability of the species in their natural habitat but also for productivity of our crop plants. Therefore, knowledge on reproductive ecology of wild and cultivated plants is important for effective management of our dwindling biodiversity and for the sustainability and improvement of the yield in crop species. Conservation and management of our plant diversity is going to be a major challenge in the coming decades, particularly in the tropical countries which are rich in biodiversity. Reproductive failure is the main driver for pushing a large number of tropical species to vulnerable category. Available data on reproductive ecology on tropical species is very limited and there is an urgent need to initiate research on these lines. A major limitation for the beginners to take up research is the absence of simple concise work manuals that provide step-wise procedures to study all aspects of reproductive ecology.
The Manual fills this void. Over 60 protocols described in the manual cover the whole spectrum of reproductive ecology - study sites and species, phenology, floral morphology and sexuality, pollen and pistil biology, pollination ecology, breeding system, seed biology, seed dispersal and seedling recruitment. Each chapter gives a concise conceptual account of the topic before describing the protocols. The Manual caters to researchers, teachers and students who are interested in any aspect of reproductive ecology of flowering plants -- botanists, ecologists, agri-horticulturists, foresters, entomologists, plant breeders and conservation biologists.
Desert flora have adapted to the extremes of heat and aridity, much like desert animals. The seasonal visitor or year round resident will find Southwestern Desert Plants to be the perfect pocket-sized, folding guide to familiar trees, shrubs, cacti and wildflowers. Richly detailed illustrations highlight over 140 familiar species found in the southwestern desert region. Created and printed in the USA, this guide was updated in 2012 with a new cover design and a back panel map highlighting prominent botanical sanctuaries. Durable and lightweight, it conveniently folds to fit into a pocket when you want to reach for your water bottle, camera or binoculars. This is the one to take on your next Southwestern desert adventure!
Ranging from miniature epiphytic orchids to towering trees, and from mangrove forests lining coastal waterways to high-elevation cloud forests, Costa Rica's rich and varied flora dazzles visitors and botanists alike. Tropical Plants of Costa Rica, the first popular treatment to include plants from all regions of the country, is an indispensable guide to native and exotic species found in the neotropics.This book is beautifully illustrated with more than 540 full-color photographs taken in the field, each depicting an entire plant or a closer view of flowers, fruits, or seeds. Instructive pen-and-ink drawings of botanical details also accompany many of the accounts. The text clearly explains each plant's identifying characteristics and reveals fascinating facts about its natural history, chemical properties, economic importance, and medicinal and other uses. Sidebar features throughout the book highlight conservation, ethnobotany, and ecology; their topics include unusual applications for plants, distinct attributes of certain plant families, and plants of particular microhabitats. Tropical Plants of Costa Rica is a wonderful resource for naturalists, students, and researchers, as well as both experienced and first-time visitors to Costa Rica and the American tropics.
Armageddon is upon us, as the two armies prepare for battle. The fate of Earth is uncertain. Armed with the blessing of the Gods, and some formidable weapons, our heroes must go against all odds and defeat the evil Stheno. Will strength or strategy prevail? In the final part of the "Wildflower" Trilogy, Hayward incorporates a clever mix of history and fantasy into this tense and thrilling finale.
The analysis of changes in gene activity in tissues and cells of plants is an important way of measuring developmental and environmental responses. This is achieved by identifying, isolating, and analyzing the genes responsible for these changes, and assessing their degree of genetic expression in relation to other cells and tissues within each plant. This book, designed as a manual, provides detailed accounts of new and established techniques used to carry out these analyses, as well as a section on trouble-shooting.
