This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Saskia Wilmsen charakterisiert die Epidermiszellformen von 37 Blütenpflanzen, um einerseits den Einfluss epidermaler Mikrostrukturen in optisch wirksamen Bereichen von Petalen hinsichtlich ihrer Attraktivität auf Hummeln zu untersuchen und andererseits deren Unterschiede in Bezug auf spektrale Reflexion und Glanzeffekte zu analysieren. Die Autorin weist nach, dass blütennaive Individuen von Bombus terrestris eine spontane Präferenz für Blütenattrappen mit konischen Zellstrukturen zeigen und stellt die Bedeutung von spektral reinen und konstanten Farbsignalen bei unterschiedlichen Anflugwinkeln der Versuchstiere heraus.

It is only recently that the immense economic value of pollination to agriculture has been appreciated. At the same time, the alarming collapse in populations of bees and other pollinators has highlighted the urgency of addressing this issue. This book focuses on the specific measures and practices that the emerging science of pollination ecology is identifying to conserve and promote animal pollinators in agroecosystems. It reviews the expanding knowledge base on pollination services, providing evidence to document the status, trends and importance of pollinators to sustainable agricultural production. It provides practical and specific measures that land managers can undertake to ensure that agroecosystems are supportive and friendly to pollinators. It draws on the Global Pollination Project, supported by UNEP/GEF and implemented by FAO and seven partner countries (Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa), which serve to provide "lessons from the field".

The tropics surround the Equator limited in latitude by the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. The tropics include all the regions on Earth where the Sun reaches a point directly overhead at least once during the solar year. The subtropics are geographic and climate zones located between the tropic circle of latitude and the 38th parallel in each hemisphere. The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region. "Tropical Conservation: Perspectives on Local and Global Priorities" drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.

Despite its economic usefulness, biodiversity of Asian hive bee Apis cerana is suffering precipitous decline and is threatened with extinction in its entire native habitat. Although a number of publications have appeared on honeybees in the market no attempt has been made to approach the subject in systematically and in a comprehensive manner in case of Apis cerana. There is still not enough knowledge on different facets of biological conservation, agricultural production and role in improving food security and livelihoods. An attempt has been made in this book to fill the gap by providing detailed information on different aspects of Apis cerana leading to sustainability and environmental protection. This book discusses information on varied aspects of Apis cerana biology, biogeography, reproduction, genetics, molecular phylogeny, interaction with other species, floral resources, dance language, safety from pesticides, management problems, loss of genetic diversity, behavioural defence, role in food production, livelihood security and conservation strategies for protecting biodiversity and enhancing crop productivity. The compilation of this book is unique in the sense that in the context of pollinator decline over the world, conservation of this species will be a step for sustaining food security.

Invertebrate Conservation and Agricultural Ecosystems explores the diverse interests of invertebrate conservation and agricultural production. It is both an introduction to invertebrate conservation biology for agriculturists and an introduction to crop protection for conservation biologists, demonstrating how these two disparate fields may draw on each other for greater collective benefit. It draws on recent literature to show how invertebrate conservation in highly altered landscapes may be promoted and enhanced. The book deals with problems of, and approaches to, invertebrate conservation in highly managed agricultural ecosystems, and how biodiversity may be promoted without compromising agricultural production. It draws attention to the importance of invertebrates in agricultural systems and their role in ecosystem functions.

There can be little doubt that there are truly colossal challenges associated with providing food, fibre and energy for an expanding world population without further accelerating already rapid rates of biodiversity loss and undermining the ecosystem processes on which we all depend. These challenges are further complicated by rapid changes in climate and its additional direct impacts on agriculture, biodiversity and ecological processes. There are many different viewpoints about the best way to deal with the myriad issues associated with land use intensification and this book canvasses a number of these from different parts of the tropical and temperate world. Chapters focus on whether science can suggest new and improved approaches to reducing the conflict between productive land use and biodiversity conservation. Who should read this book? Policy makers in regional, state and federal governments, as well as scientists and the interested lay public.

A growing body of evidence shows that agricultural landscapes can be managed not only to produce crops but also to support biodiversity and promote ecosystem health. Innovative farmers and scientists, as well as indigenous land managers, are developing diverse types of “ecoagriculture” landscapes to generate cobenefits for production, biodiversity, and local people. Farming with Nature offers a synthesis of the state of knowledge of key topics in ecoagriculture. The book is a unique collaboration among renowned agricultural and ecological scientists, leading field conservationists, and farm and community leaders to synthesize knowledge and experience across sectors. The book examines: the knowledge base for ecoagriculture as well as barriers, gaps, and opportunities for developing improved ecoagriculture systems what we have learned about managing landscapes to achieve multiple objectives at a landscape scale existing incentives for farmers, other land managers, and investors to develop and invest in ecoagriculture systems pathways to develop, implement, manage, and scale up successful ecoagriculture Insights are drawn from around the world, in tropical, Mediterranean, and temperate environments, from farming systems that range from highly commercialized to semi-subsistence. Farming with Nature is an important new work that can serve as a foundation document for planners, farm organizations, researchers, project developers, and policy makers to develop strategies for promoting and sustaining ecoagriculture landscapes. Replete with valuable best practice guidelines, it is a critical resource for both practitioners and researchers in the field.
