Book Description
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.

Book Description
Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.

Book Description
Stingless bees (Meliponini) are the largest and most diverse group of social bees, yet their largely tropical distribution means that they are less studied than their relatives, the bumble bees and honey bees. Stingless bees produce honey and collect pollen from tens of thousands of tropical plant species and, in the process, provide critical pollination services in the tropics. Like many other insects, they are struggling with new human-made challenges like habitat destruction, climate change and new diseases. This book provides an overview of stingless bee biology, with chapters on the evolutionary history, nesting biology, colony organisation and division of labour of stingless bees. In addition, it explores their defence strategies, foraging ecology, and varied communication methods. Accordingly, the book offers an accessible introduction and reference guide for students, researchers and laypeople interested in the biology of bees.

Book Description
If nothing else, 2020 reminded us that, whether we like it or not, human society forms part of a broader ecological community that includes species with management challenges. My experience in Melbourne highlighted how environmental threats to humanity are best managed when governments adopt evidence-based strategies (that might also require incentives for human cooperation). Fundamental research, ranging from quantitative natural history to broader insights about ecological and evolutionary processes, invariably forms the backbone of such evidence. The collection of papers in this 2020 Highlights eBook represents a sample of articles in Frontiers in Ecology and Evolution that contribute to our collective wisdom in the discipline and generated sizeable interest among our readers. We hope you also find them interesting.

Book Description
Seeley, a world authority on honey bees, sheds light on why wild honey bees are still thriving while those living in managed colonies are in crisis. Drawing on the latest science as well as insights from his own pioneering fieldwork, he describes in extraordinary detail how honey bees live in nature and shows how this differs significantly from their lives under the management of beekeepers. Seeley presents an entirely new approach to beekeeping--Darwinian Beekeeping--which enables honey bees to use the toolkit of survival skills their species has acquired over the past thirty million years, and to evolve solutions to the new challenges they face today. He shows beekeepers how to use the principles of natural selection to guide their practices, and he offers a new vision of how beekeeping can better align with the natural habits of honey bees.
