Book Description
In many ecosystems dung beetles play a crucial role--both ecologically and economically--in the decomposition of large herbivore dung. Their activities provide scientists with an excellent opportunity to explore biological community dynamics. This collection of essays offers a concise account of the population and community ecology of dung beetles worldwide, with an emphasis on comparisons between arctic, temperate, and tropical species assemblages. Useful insights arise from relating the vast differences in species' life histories to their population and community-level consequences. The authors also discuss changes in dung beetle faunas due to human-caused habitat alteration and examine the possible effects of introducing dung beetles to cattle-breeding areas that lack efficient native species. "With the expansion of cattle breeding areas, the ecology of dung beetles is a subject of great economic concern as well as one of intense theoretical interest. This excellent book represents an up-to-date ecological study covering important aspects of the dung beetle never before presented."--Gonzalo Halffter, Instituto de Ecologia, Mexico City Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
The sweeping scientific and social history of the humble dung beetle The humble and industrious dung beetle is a marvelous beast: the 6,000 species identified so far are intricately entwined with human history and scientific endeavor. These night-soil collectors of the planet have been worshipped as gods, worn as jewelry, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilize soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world. In this sweeping history of more than 3,000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer Helen Lunn capture the diversity of dung beetles and their unique behavior patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy. With over 6,000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the center of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike.

Book Description
This book describes the evolutionary and ecological consequences of reproductive competition for scarabaeine dung beetles. As well as giving us insight into the private lives of these fascinating creatures, this book shows how dung beetles can be used as model systems for improving our general understanding of broad evolutionary and ecological processes, and how they generate biological diversity. Over the last few decades we have begun to see further than ever before, with our research efforts yielding new information at all levels of analysis, from whole organism biology to genomics. This book brings together leading researchers who contribute chapters that integrate our current knowledge of phylogenetics and evolution, developmental biology, comparative morphology, physiology, behaviour, and population and community ecology. Dung beetle research is shedding light on the ultimate question of how best to document and conserve the world's biodiversity. The book will be of interest to established researchers, university teachers, research students, conservation biologists, and those wanting to know more about the dung beetle taxon.

Book Description
For a relatively small group of insects, dung beetles have attracted an inordinate amount of scientific interest over the years. This started with the work of the famous French naturalist Jean-Henri Fabre about 100 years ago, but it the work of Gonzalo Halffter of Mexico, and his colleagues, who first placed dung beetles on the scientific map by the publication of two important synthetic works. The first was published in 1966 ("Natural History") and this was followed by another in 1982 ("Nesting and Breeding Behaviour"). A multi-authored book on dung beetle ecology, edited by Ilkka Hanski and Yves Cambefort, was published in 1991. These volumes are long out of print and mostly unavailable. In the 18 years since the last book was published there has been a steady stream of research published on dung beetle phylogeny, biogeography, physiological ecology and conservation, fields that were not, or barely treated in the previous books. The current work synthesises and updates most of the major elements covered in those studies, but introduces several novel sections in a phylogenetic approach to the natural history of dung beetles. The aspects covered, in five sections, are the following: evolution and ecological success of dung beetles; physiological and behavioural ecology of dung beetles; phylogeny of the Scarabaeinae; historical biogeography of the Scarabaeinae and its physical and biotic drivers; and, conservation of dung beetles. The content of the book is balanced in such a way that the information contained in it should be of interest to general entomologists, research specialists on dung beetle natural history, insects systematists, students of entomology, agricultural scientists and insect conservationists.

Book Description
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Book Description
“Profiles 600 of the most stunning, most wonderfully adapted beetles around . . . The result is a work that is nothing short of magnificent.” —Wired When renowned British geneticist J. B. S. Haldane was asked what could be inferred about God from a study of his works, Haldane replied, “An inordinate fondness for beetles.” With 350,000 known species, and scientific estimates that millions more have yet to be identified, their abundance is indisputable as is their variety. They range from the delightful summer firefly to the one-hundred-gram Goliath beetle. Beetles offer a dazzling array of shapes, sizes, and colors that entice scientists and collectors across the globe. The Book of Beetles celebrates the beauty and diversity of this marvelous insect. Six hundred significant beetle species are covered, with each entry featuring a distribution map, basic biology, conservation status, and information on cultural and economic significance. Full-color photos show the beetles both at their actual size and enlarged to show details, such as the sextet of spots that distinguish the six-spotted tiger beetle or the jagged ridges of the giant-jawed sawyer beetle. Based in the most up-to-date science and accessibly written, the descriptive text will appeal to researchers and armchair coleopterists alike. The humble beetle continues to grow in popularity, taking center stage in biodiversity studies, sustainable agriculture programs, and even the dining rooms of adventurous and eco-conscious chefs. The Book of Beetles is certain to become the authoritative reference on these remarkably adaptable and beautiful creatures. “Photographs of more than 600 colorful, glossy species, resembling bejeweled broaches morethan creepy crawlies, are presented at actual size.” —Publishers Weekly

Book Description
Liberia’s oligarchy: The beginning of the end. 2019 Grand Prize Winner - Red City Review Based on the remarkable true account of a young American who landed in Liberia in 1961. *****The story weaves drama, dark comedy, and romance throughout a rich tapestry of narration - The San Francisco Book Review KEN VERRIER IS NOT HAPPY, NOR AT PEACE. He is experiencing the turbulence of Ishmael and the guilt of his brother's death. His sudden decision to drop out of college and del with his demons shocks his family, his friends, and especially his girlfriend, soon to have been his fiancee. His destination: Liberia - The richest country in Africa both in monetary wealth and in natural resources. NOTHING COULD HAVE PREPARED HIM FOR THE EXPERIENCES HE WAS ABOUT TO LIVE THORUGH. Ken quickly realizes that he has arrived in a place where he understands very little of what is considered normal, where the dignity of life has little meaning, and where he can trust no one. Flying into the interior bush as a transport piolot, Ken learns quickly. He witnesses, first-hand, the disparate lives of the Liberian "Country People? and the "Congo People" also known as Americo-Liberians. These descendants of President Monroe's American Colonization Policy that sent freed slaves back to Africa in the 1800's have set up a strict hierarchical society not unlike the antebellum South. Author Dan Meier describes Ken's many escapades, spanning from horrifying to whimical, with engaging and fast-moving narrative that ultimately describes a society upon which the wealthy are feeding and in which the poor are being buried. It's a novel that will stay with you long after the last word has been read.
