It is human nature to measure things, and this holds true for science as well as everyday life. The five papers in this book demonstrate the usefulness of a morphometric approach to a variety of subjects in natural history, including systematics, phenotypic plasticity in response to environmental variation, and ontogenetic adaptation. As our understanding of genetic control mechanisms and epigenetics has matured over the last several decades, it has become clear that morphometric assessment continues to be important to our overall understanding of natural variability in growth and form. The tremendous growth of our knowledge base during the last century has necessitated that we find new ways to measure and track greater detail as well as greater numbers of parameters among populations and individuals.

"Examines the history of the British fire service from 1800-1980, embracing certain key themes of modern British history: the impact of industrial change on urban development, the effect of disaster on political reform, the growth of the state, and the relationship between masculinity and trade unionism in creating a professional identity"--Provided by publisher.

In The Natural History of Bumblebees, biologists Carol A. Kearns and James D. Thomson give amateurs and professionals alike the basic knowledge to pursue the joys of observing and investigating these attractive and amenable subjects. Packed with information on bumblebee colonies, bee honeypots, bee development, foraging behavior, as well as instructions for maintaining bumblebees in captivity, this lively and colorful book also includes an easy-to-use photographic field guide to aid in the identification of over fifty species of North American bumblebee-virtually every known species on this continent. Until now, even the basic identification of North American bumblebees has been through the use of highly technical regional keys. The Natural History of Bumblebees fills a gap in the literature and provides amateur enthusiasts, educators, and scholars the information to develop their own projects in bumblebee biology. Kearns and Thomson also provide detailed instructions for constructing simple equipment that facilitates bee wrangling: the handling, tagging, studying, and raising of bumblebees. They present suggestions for research projects and identify areas of incomplete knowledge requiring further research. This book is an invaluable reference for students and scholars of native pollinators and an indispensable resource for naturalists, gardeners, and anyone who has ever been fascinated by the flight of the bumblebee.

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.

This book brings together scientific evidence and experience relevant to the practical conservation of wild bees. The authors worked with an international group of bee experts and conservationists to develop a global list of interventions that could benefit wild bees. They range from protecting natural habitat to controlling disease in commercial bumblebee colonies. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bees quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bee conservation actions throughout the world. Bee Conservation is the first in a series of synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)’s Unified Classification of Direct Threats.
