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.
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.
The flora of China is astonishing in its diversity. With 32,500 species of vascular plants, over fifty per cent of which are endemic, it has more botanical variety than anywhere else in the world and provides unbroken connections to all its landscapes - from tropical to subtropical, temperate and boreal forests. This book tells the story of the plants of China: from the evolution of the flora through time to the survey of the bioclimatic zones, soundly based on chapters with information on climate, physical geography and soils. The history of botany and its study are also examined, with chapters dedicated to forestry, medicinal plants and ornamentals, with the changing flora, aliens, extinction and conservation also discussed. An essential read for years to come, The Plants of China shows that an understanding of the flora of China is crucial to interpreting plant evolution and fossil history elsewhere in the world.
Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Their often rich variety of resources makes them highly valuable to the peoples who live With a few exceptions (like the Everglades in the or regularly stay in them.

George loves to go to the science museum. So, when he finds out that the museum is planning a "Green Day" dedicated to recycling and planting trees, and George is curious and wants to help out But little monkeys eager to help can sometimes become little monkeys getting into trouble. When George begins to find and recycle things around town that aren't quite ready for the recycle bin, he gets into a jam. Thankfully, George isn't the only one who wants to help--the whole community can't wait to lend a hand--and help George and the museum plant some trees
