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 European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 3 contains accounts of 47 families, including those formerly included in the Leguminosae (Mimosaceae, Caesalpiniaceae, Fabaceae) as well as the large and important Rosaceae. Also included are those families formerly covered by the name Saxifragaceae (Saxifragaceae in the strict sense, Penthoraceae, Grossulariaceae, Parnassiaceae, Hydrangeaceae and Escalloniaceae).
This concise guide shows novice houseplant owners exactly how to keep indoor plants alive and healthy. Gardening expert Ellen Zachos helps you choose the right plants in the first place and then shows you how to care for them, outlining what each kind needs in terms of location, sunlight, water, and fertilizer. She also explains when plants should be repotted (and how to do that successfully), how and when to prune them, how to keep them clean of dust and pets, and more. This Storey BasicsÂ® guide has all the information you need to keep any houseplant thriving and beautiful!
For the last two decades the loss of, in particular, tropical rainforest has alarmed the public in the developed parts of the world. The debate has been characterised by a lack of understandÂ ing of the causes and effects of the process, leading to the prevailing reaction being unqualiÂ fied condemnation. Such attitude has even been observed among scientists, claiming supremÂ acy to biodiversity conservation. Many scientific analyses are available, but the basis for soÂ ber debates and appropriate actions is still highly insufficient. Two recent international initiaÂ tives! will hopefully lead to improved knowledge of deforestation and forest degradation as they recognise the need for studies to critically investigate those issues. This book will proÂ vide useful input to the initiatives. In my opinion, the scientific analyses have not sufficiently promoted the understanding that the fate of tropical forests is first and foremost a concern of the governments of the countries in which the forests are situated. Tropical forests may be important to the global environment and their rich biodiversity may be a human heritage. But their main importance is their potenÂ tial contribution to improving livelihood in the countries in question.
