There are over 40 000 named species of mite, and if estimates for unnamed species are included, then up to 1 million may grace the planet. By comparison, there are approximately 40 000 species of vertebrates, half of them fish, alive today. Mites are predators, parasites, herbivores and detritivores. They live in the dark depths of the ocean, in the lungs of birds, on the leaves of rainforest plants, and in human clothes and bedding. They are vectors of disease, vital players in soil formation, and important agents of biological control. Despite the grand diversity of mites, these small arthropods are often overlooked, and even trained biologists can be unaware of their significance. This books aims to fill the gap in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites, without requiring prior knowledge of their morphology or taxonomy. The text is richly illustrated with line drawings and photographs. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, and mites as models of ecological and evolutionary theories.

The Acari, comprising mites and ticks, form one of the largest and biologically most diverse groups of the Arachnida. They are worldwide in distribution and rival the insects in the extent to which they have successfully colonized terrestrial and aquatic habitats. Some are significant crop pests, while ticks are parasites on a wide range of vertebrate hosts. This diversity of modes of life is reflected in their morphology and life-history strategies.
This book provideds a detailed introduction to the Acari, concentrating on their functional morphology, but also covering their classification and economic importance. It will serve as a text and reference for acarologists and advanced-level students taking courses in general entomology (which traditionally include acarology), invertebrate zoology, and agricultural, medical and veterinary 'entomology.'

Ticks of the Southern Cone of America: Diagnosis, Distribution and Hosts with Taxonomy, Ecology and Sanitary Importance focuses on the tick species prevalent in The Southern Cone of America, including their distribution, biology, associated pathogens, their effects on the host, and control methods. Based on review of the literature from more than five decades, 62 species of both hard and soft tick have been discovered on the Southern Cone of America. Tick genera observed and recorded include Amblyomma, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus.

Concentrating on the complex spider communication system, this book assembles the most recent multidisciplinary advances of leading researchers from many countries to assess the peculiar role spiders play in the animal kingdom. Originally published in 1982. 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.

Until now, individuals wishing to identify British insects have found it difficult to track down the specialist keys published in obscure literature, whereas the popular guides are often misleadingly simplistic, covering only a fraction of the species. This book bridges the gap, providing expert guidance through the taxonomic maze. It contains an introduction to each group of organisms, and over 2000 references selected as being the most useful and up-to-date for accurate identification, together with notes on their relevance and coverage. A further chapter covers the understanding and retrieval of scientific references, with advice on using libraries and other information services. This will be an essential reference book for anyone involved in insect and arachnid identification, from interested amateurs to professionals dealing with unfamiliar groups.

This comprehensive survey demonstrates the value of scorpions as model systems for investigating a wide range of biological questions, from neurobiology to evolutionary ecology.

Insects and arachnids display the most impressive diversity of mating and social behavior among all animals. This book investigates sexual competition in these groups, and the variety of ways in which males and females pursue, persuade, manipulate, control and help one another, enabling us to gain a better understanding of how conflicts and confluences of interest evolve together. Each chapter provides a comprehensive review of mating systems in particular insect and arachnid groups, discusses intrinsic and extrinsic factors responsible for observed mating strategies, and suggests fruitful avenues for further research. The book culminates in a synthesis, reviewing the data in terms of the theory of sexual conflict. This broad-based book will be of immense value to students and researchers interested in reproductive strategies, behavioral ecology, entomology and arachnology.

As experimental organisms, spiders offer ecologists a unique opportunity to examine the concept of the ecological community and the role which field experimentation can play in evaluating theories of population and community ecology. In this book, David Wise provides a balanced critique of field experiments designed to uncover details of spider ecology, with the dual aim of clarifying the ecology of these fascinating organisms and providing insight into the advantages and challenges of performing field experiments with a predator ubiquitous in terrestrial ecosystems. This book should be an essential reference for all ecologists wishing to learn more about the ecology of a major terrestrial predator and the use of field experimentation as a powerful technique to test ecological hypotheses.

Visitors to tropical forests generally come to see the birds, mammals, and plants. Aside from butterflies, however, insects usually do not make it on the list of things to see. This is a shame. Insects are everywhere, they are often as beautiful as the showiest of birds, and they have a fascinating natural history. With their beautifully illustrated guide to insects and other arthropods, Paul E. Hanson and Kenji Nishida put the focus on readily observable insects that one encounters while strolling through a tropical forest in the Americas. It is a general belief that insects in the tropics are larger and more colorful than insects in temperate regions, but this simply reflects a greater diversity of nearly all types of insects in the tropics. On a single rainforest tree, for example, you will find more species of ant than in all of England.Though written for those who have no prior knowledge of insects, this book should also prove useful to those who study them. In addition to descriptions of the principal insect families, the reader will find a wealth of biological information that serves as an introduction to the natural history of insects and related classes. Sidebars on insect behavior and ecological factors enhance the descriptive accounts. Kenji Nishida's stunning photographs-many of which show insects in action in their natural settings-add appeal to every page. A final chapter provides a glimpse into the intriguing world of spiders, scorpions, crabs, and other arthropods.

In the crab spider, Misumena vatia, Douglass H. Morse and his colleagues found an ideal species on which to test basic questions associated with lifetime fitness. From the moment a female crab spider selects a flower on which to sit and wait for her prey, there unfolds a cascade of lifetime fitness variables that determine her evolutionary success. Did she choose a flower that attracts suitable prey? Will she encounter a competitor or predator? Will she survive long enough to breed, and will her offspring contribute to the gene pool? Ecologists had previously identified variables that shape populations, but lacked the experimental data needed to make comprehensive tests of individuals that made different foraging decisions. Morse found that Misumena is particularly well suited to both field study and laboratory experiments. Over the last 25 years, his simple yet elegant experiments have contributed to our understanding of lifetime fitness and helped to develop study techniques that can be applied to animals with other, more complex, life histories. "Predator upon a Flower" recounts these influential discoveries in a gracefully crafted narrative that moves ever outward from individuals to communities to ecosystems, and concludes by suggesting directions for future research in spider biology.

Ticks in the genus Rhipicephalus include many important vectors of animal and human pathogens, but many species are notoriously difficult to identify, particularly as immature stages. This reference volume provides identification keys for adult ticks from the Afrotropical regions and elsewhere. For the nymphs and larvae, unique plates have been compiled in which line drawings of the capitula of similar species are grouped together to facilitate identification. Brief well-illustrated descriptions of the known stages of every species are given, plus information on their hosts, distribution, and disease relationships. Tables providing data on host/parasite relationships and disease transmission are also included, making this the definitive reference source on this group for all those interested in acarology, veterinary or medical parasitology and entomology for many years to come.

The brown recluse is a fascinating spider very well adapted to dwelling in houses and other buildings. Because of this very quality and the ghastly reputation associated with the medical consequences of its bite, it has become infamous throughout North America. Although recluse spiders can cause serious skin injuries and, in very rare cases, death, the danger posed by this spider is often exaggerated as a result of arachnophobia and the misdiagnosis of non-spider-related conditions as brown recluse bites. These misdiagnoses often occur in areas of North America where the spider does not exist, making legitimate bites improbable. One of the greatest factors that keeps the myths alive is misidentification of common (and harmless) spiders as brown recluses. With this book, Richard S. Vetter hopes to educate readers regarding the biology of the spider and medical aspects of its bites, to reduce the incidence of misdiagnoses, and to quell misplaced anxiety. In The Brown Recluse Spider, Vetter covers topics such as taxonomy, identification, misidentification, life history characteristics and biology, medical aspects of envenomations, medical conditions misdiagnosed as brown recluse bites, other spider species of medical consideration (several of which have been wrongly implicated as threats to human health), and the psychology behind the entrenched reasons why people believe so deeply in the presence of the spider in the face of strong, contradictory information. Vetter also makes recommendations for control of the spider for households in areas where the spiders are found and describes other species of recluse spiders in North America. Although The Brown Recluse Spider was written for a general audience, it is also a valuable source of information for arachnologists and medical personnel.

Spinnen sind Super-Raubtiere und vertilgen alles, was sie uberwaltigen koennen. Dafur haben sie unglaublich gute Fangtechniken und mit der Spinnenseide ein Werkzeug entwickelt, das die Materialtechnik vor Neid erblassen lasst. Die Mannchen sind meist kleiner als die Weibchen und mussen sich, um nicht als leichte Beute missverstanden zu werden, beim Sex einiges einfallen lassen: Tanzen, Trommeln und Geschenke helfen fast immer. Spinnen benutzen ihr Gift sehr genau dosiert, und da der Mensch nicht auf ihrem Speisezettel steht, sind sie fur uns harmlos. Die (unnoetige) Angst vieler Menschen vor Spinnen findet kulturelle Wurzeln bereits im Mittelalter. Trotzdem ist Spinnenangst leicht therapierbar. Es gibt weder einen Lebensraum noch ein Gebaude ohne Spinnen. Und das ist gut so, denn sie verfugen uber faszinierende Eigenschaften und ihre Welt ist voller UEberraschungen. Alles, was man hierzu wissen muss, wird in diesem Buch in verstandlicher Sprache von Fachleuten fur Laien erklart. Zudem werden einige der haufigsten Spinnenarten in Haus und Garten mit Tipps zur Beobachtung kurz vorgestellt.

Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. Spiders by Cecil Warburton was first published in 1912. The volume presents an account of the habits and modes of life of spiders, with additional information regarding methods of observation and research.

'Social' insects and arachnids exhibit forms of complex behaviour that involve cooperation in building a nest, defending against attackers or rearing offspring. This book is a comprehensive, up-to-date guide to sociality and its evolution in a wide range of taxa. In it, leading researchers review the extent of sociality in different insect and arachnid groups, analyse the genetic, ecological and demographic causes of sociality from a comparative perspective and suggest ways in which the field can be moved on. It contains fascinating accounts of the social lives of many different insects and arachnids, as well as tests of current theories of the evolution of social behaviour. The Evolution of Social Behaviour in Insects and Arachnids provides essential reading and insight for students and researchers interested in social behaviour, behavioural ecology, entomology and arachnology.

Spiders, objects of eternal human fascination, are found in many places: on the ground, in the air, and even under water. Leslie Brunetta and Catherine Craig have teamed up to produce a substantive yet entertaining book for anyone who has ever wondered, as a spider rappelled out of reach on a line of silk, "How do they do that?" The orb web, that iconic wheel-shaped web most of us associate with spiders, contains at least four different silk proteins, each performing a different function and all meshing together to create a fly-catching machine that has amazed and inspired humans through the ages. Brunetta and Craig tell the intriguing story of how spiders evolved over 400 million years to add new silks and new uses for silk to their survival "toolkit" and, in the telling, take readers far beyond the orb. The authors describe the trials and triumphs of spiders as they use silk to negotiate an ever-changing environment, and they show how natural selection acts at the genetic level and as individuals struggle for survival.

In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the 1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

This book presents current research in the study of the morphology, behaviour and geographic distribution of spiders. Topics discussed include plasticity in spider webs and silk; spider webs as extended phenotypes; the structure and function of the lipoproteins of spiders; a study of the discriminate information on spider webs; and ant mimicry in spiders.

Ticks are obligate blood sucking arthropods found in almost every region of the world. They are very important vectors of human and animal diseases. Tick-borne protozoan diseases such as Theileriasis and Babesiosis cause mortality and morbidity in domestic animals in many countries including India. An understanding of taxonomy, vector biology and ecology in the geographic regions of each country is essential so that a programme of control measures can be implemented. This book focuses on the ticks found in India and will be invaluable for health authorities, tick biologists and veterinary researchers. It covers taxonomic identification, medical importance and bionomics of haemaphysaline ticks.

In the thirty years since the second edition of A Manual of Acarology was published, acarologists have discovered a multitude of new mite taxa, made major modifications in acarine classification, and profoundly altered their understanding of this vast group, inspiring new and innovative approaches to resolving many basic and applied acarological problems. Now, this completely revised and updated reference, the most comprehensive and recent in the discipline, is 04 Activeable to researchers, teachers, students, and plant and animal scientists wishing to explore the complex and often astonishing world of mites. The third edition remains primarily taxonomic in approach, but it also provides detailed information on subjects that include phylogeny, biology, morphology, systematics, ecology, and behavior. The editors discuss collection and rearing techniques in detail, along with specimen preparation and methods of preservation. Taxonomic diagnoses for the 124 presently recognized superfamilies of Acari are included in their appropriate systematic chapters, and feeding habits, host range, and distribution of member families and representative species are discussed under each superfamilial heading. The authors complement their text with keys to families (with the Ixodida keyed to genus), a bibliography comprising more than 4,000 entries, and a detailed index. More than 1,330 labeled line drawings and scanning electron micrographs illustrate the text. Unlike previous editions, the third is the product of a team effort by ten authors whose contributions have been amalgamated into a seamless text. In addition to the editors, the contributors are V. M. Behan-Pelletier, D. R. Cook, M. S. Harvey, J. E. Keirans, E. E. Lindquist, R. A. Norton, B. M. OConnor, and I. M. Smith, all leading experts in their areas of acarology.
