Book Description
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.

Book Description
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.

Book Description
Most flowering plants, including wild species and many food crops, are pollinated by animals and are vital, therefore, for biological production and the maintenance of biodiversity. Pollinators benefit from diverse natural habitats for forage and nesting, especially when these are limited in plant production systems. Landscape and forest management practices can help ensure the continued availability of pollinators and thereby increase resilience and the productivity of forestry and agriculture. The extent of forests and other natural habitats in a landscape plays a role in determining the species composition of pollinators. Agricultural landscapes adjoining fragmented forests and natural areas benefit from pollinator services, and animal-pollinated crops therefore achieve higher fruit set. Forest management practices can have significant effects on pollinator abundance and diversity. They affect forest variables such as structure, species composition, soil dynamics, hydrology and light availability, all of which can affect pollinator species composition and diversity and plant–pollinator networks. Indigenous and local knowledge can contribute to the conservation of pollinators through traditional management practices. This working paper, which is aimed at forest practitioners, landscape planners and land-use decision-makers, reviews published literature on the impacts of forest and landscape management practices on pollinators. It also addresses the implications of climate change, collates 36 case studies, and makes recommendation on measures for maintaining pollinator diversity and abundance in forests and landscapes

Book Description
This new collection focuses on the impact of sprawl on biodiversity and the measures that can be taken to alleviate it. Leading biological and social scientists, conservationists, and land-use professionals examine how sprawl affects species and alters natural communities, ecosystems, and natural processes. The contributors integrate biodiversity issues, concerns, and needs into the growing number of anti-sprawl initiatives, including the "smart growth" and "new urbanist" movements.

Book Description
World Bee Day takes place on the 20th of May, commemorating the date on which we acknowledge the influence of the most popular pollinator species, bees, in plant diversity and our society. The aim of this Research Topic is to raise awareness of the importance of pollinators in urban areas, the threats they face and their contribution to sustainable development. It is in this spirit that Frontiers is launching a new article collection to coincide with this UN day. This occasion not only offers an opportunity to acknowledge the sustainable approach that is protecting wildlife in any form in urban areas, but also to consider the importance of bees in our ecosystem and their positive impact on human society. This Frontiers in Sustainable Cities Research Topic aims to address Urban Greening and Resource Management-specific dimensions of this UN day, highlighting the importance of having healthy green areas and all-level decision-making and considering how pollinators interact with many levels of our society. Topics may include, but are by no means limited to: - Technology and practices for urban greening and pollinator populations - Urban solutions for declining bee populations - Influence of community gardens on pollinator populations - Increases of the awareness of the importance of pollinators in local community gardens and urban greening - Policy making to protect pollinators in urban areas - Facilitating urban management of natural resources for the benefit of pollinator populations - Harnessing SDGs for urban pollinators population - Citizen science to monitor pollinators - Pollination service in urban areas - Effects of environmental contaminants, climate warning and light on pollinators - Plant pollinator networks in cities and urban areas

Book Description
Insects do not live in isolation. They interact with the abiotic environment and are major components of the terrestrial and freshwater biotic milieus. They are crucial to so many ecosystem processes and are the warp and weft of all terrestrial and freshwater ecosystems that are not permanently frozen. This means that insect conservation is a two-way process: insects as the subjects of conservation, while also they are useful tools for conserving the environment. This book overviews strategic ways forward for insect conservation. It is a general view of what has worked and what has not for the maintenance of insect diversity across the world, as well as what might be the right approaches for the future.
