"Bees play an essential role in the pollination of native plants and agricultural crops across the globe. In North America alone there are more than 4,000 bee species. In spite of their abundance and diversity, there is no accessible field guide for the non-expert. This book will remedy that situation by providing a carefully crafted introduction to bee identification for eastern North America. No portable field guide could include coverage of the myriad species in the region, so the book concentrates on identifying bees at the genus level. It includes information on the 72 different genera that are found east of the Rockies"--

The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.

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

This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.

In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts.".

The Dorylaimida represent a large and very important group of soil and freshwater inhabiting nematodes of great agricultural importance. Both in appearance and mode of life they represent a wide diversity and as a consequence the number of species and higher taxa that have been described hitherto is the highest within Nematoda. The identification of species, genera, families, etc. of Dorylaimida is very difficult and at times causes problems for the specialist too. The large number of species on the one hand and often the meagre descriptions on the other make even well-known taxonomists to look at Dorylaimida with great hesitation and desperation. M. Shamim Jairajpuri and Wasim Ahmad have undertaken a great task in summarizing, evaluating and systematizing all the knowledge that has been published so far.
