A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Recognizing the importance of invertebrate pollinators, the Commission on Genetic Resources for Food and Agriculture (Commission) at its Seventeenth Regular Session, in 2019, adopted its Work Plan for the Sustainable Use and Conservation of Microorganism and Invertebrate Genetic Resources for Food and Agriculture and decided to address pollinators, including honey bees, at its Nineteenth Regular Session. Building on global assessments addressing pollinators published in 2016 and 2019, respectively, by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and FAO, this study provides up-to-date information on the status and trends of invertebrate pollinators, maps relevant regional and international initiatives, and identifies gaps and needs.

Pest management for vegetable crops and safety provision for the pollinators is a challenging task in the context to increase vegetable productivity without upsetting the ecological balance. The book Pests and Pollinators of Vegetable and Oilseed Crops aims to integrate and develop pest control strategies by minimizing their impact on beneficial insect species such as natural enemies and pollinators for enhancing fruit production and quality. A detailed account is provided on pests and pollinators of oilseed crops such as Cruciferous, Solanaceous, Umbelliferous, Cucurbitaceous, Malvaceous, Leguminous and Alliaceae. The compilation of this book is unique as it does not deal only with the conventional way of pest management for different crops; it takes into consideration the role of pollinators and their profitable utilization in the larger context of ecologically based pest management and safety of pollinators. An exemplary attempt is made to promote a large, diverse, sustainable and dependable bee pollinator workforce that can meet the challenges of optimizing food production in the twenty-first century and beyond.

There is consensus that loss of biodiversity is a defining feature of the Anthropocene, with potentially severe consequences for human food security and well-being. Of particular concern are global declines in insect pollinators, such as bees, flies, beetles and butterflies, as their roles in sustaining ecosystem functions and ensuring food production are indispensable. A wide array of abiotic and biotic stressors likely govern the observed insect declines and losses of wild and managed insect pollinators, respectively. For instance, habitat destruction and fragmentation can not only lead to smaller and isolated populations that are vulnerable to environmental stochasticity or inbreeding depression, but also lead to poor nutrition as floral abundance and diversity are reduced. Further key stressors are pests and pathogens, climate change, intensified agriculture and environmental pollution (e.g., pesticides). These environmental stressors may interact with one another and generate complex effects that amplify the direct consequences of a single given stressor. Unfortunately, there is a lack of knowledge concerning how even the most important environmental stressors may interact to affect insect pollinators. The goal of this effort is to develop a platform that brings together the latest information on how abiotic and biotic stressors interact to impact insect pollinator health. Only by bringing together different lines of evidence will we be able to better predict how these environmental stressors will affect insect pollinators. An improved understanding will also facilitate the development of more effective and sustainable management strategies that will enable stakeholders to implement adequate and sustainable measures to safeguard insect pollinators. This Research Topic welcomes both Original Research and Reviews, as well as Commentary or Opinion articles that address the topic of environmental stressor interactions, and their impact on insect pollinator health. Submissions should be based on, but not limited to: - How combined environmental stressors affect insect pollinators using molecular, physiological, behavioral, ecological or evolutionary approaches - Experimental or survey work conducted under laboratory, semi-field, or field conditions - Unravelling the mechanisms underlying combined stressor interactions - What can be done to limit the impact of combined environmental exposure in the field

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.

We should thank a pollinator at every meal. These diminutive creatures fertilize a third of the crops we eat. Yet half of the 200,000 species of pollinators are threatened. Birds, bats, insects, and many other pollinators are disappearing, putting our entire food supply in jeopardy. In North America and Europe, bee populations have already plummeted by more than a third and the population of butterflies has declined 31 percent. Protecting Pollinators explores why the statistics have become so dire and how they can be reversed. Jodi Helmer breaks down the latest science on environmental threats and takes readers inside the most promising conservation initiatives. Efforts include famers reducing pesticides, cities creating butterfly highways, volunteers ripping up invasive plants, gardeners planting native flowers, and citizen scientists monitoring migration. Along with inspiring stories of revival and lessons from failed projects, readers will find practical tips to get involved. They will also be reminded of the magic of pollinators—not only the iconic monarch and dainty hummingbird, but the drab hawk moth and homely bats that are just as essential. Without pollinators, the world would be a duller, blander place. Helmer shows how we can make sure they are always fluttering, soaring, and buzzing around us.
