There is not just one story of silk. In silk is science, history and mythology. In silk is the future. Aarathi Prasad’s Silk is a gorgeous new history weaving together the story of a unique material that has fascinated the world for millennia. Through the scientists who have studied silk, and the biology of the animals from which it has been drawn, Prasad explores the global history, natural history, and future of a unique material that has fascinated the world for millennia.For silk, prized for its lightness, luminosity, and beauty is also one of the strongest biological materials ever known. More than a century ago, it was used to make the first bulletproof vest, and yet science has barely even begun to tap its potential. As the technologies it has inspired – from sutures to pharmaceuticals, replacement body parts to holograms – continue to be developed in laboratories around the world, they are now also beginning to offer a desperately needed, sustainable alternative to the plastics choking our planet.Prasad's Silk is a cultural and biological history from the origins and ancient routes of silk to the biologists who learned the secrets of silk-producing animals, manipulating the habitats and physiologies of moths, spiders and molluscs. Because there is more than one silk, there is more than one story of silk. More than one road, more than one people who discovered it, and wove its threads.From the moths of China, Indonesia and India to the spiders of South America and Madagascar, to the silk-producing molluscs of the Mediterranean, Silk is a book rich in the passionate connections made by women and men of science to the diversity of the animal world. It is an intoxicating mix of biography, intellectual history and science writing that brings to life the human obsession with silk.

A rich and surprising exploration of the intelligence of bees Most of us are aware of the hive mind—the power of bees as an amazing collective. But do we know how uniquely intelligent bees are as individuals? In The Mind of a Bee, Lars Chittka draws from decades of research, including his own pioneering work, to argue that bees have remarkable cognitive abilities. He shows that they are profoundly smart, have distinct personalities, can recognize flowers and human faces, exhibit basic emotions, count, use simple tools, solve problems, and learn by observing others. They may even possess consciousness.Taking readers deep into the sensory world of bees, Chittka illustrates how bee brains are unparalleled in the animal kingdom in terms of how much sophisticated material is packed into their tiny nervous systems. He looks at their innate behaviors and the ways their evolution as foragers may have contributed to their keen spatial memory. Chittka also examines the psychological differences between bees and the ethical dilemmas that arise in conservation and laboratory settings because bees feel and think. Throughout, he touches on the fascinating history behind the study of bee behavior.Exploring an insect whose sensory experiences rival those of humans, The Mind of a Bee reveals the singular abilities of some of the world’s most incredible creatures.

Sociala byggnadskonstnärer. När myror och getingar kommer på tal väcks olika känslor inom oss. De kan vara av det negativa slaget om man fått myror i brallan av att ha suttit på en tuva med rödmyror eller råkat komma åt ett getingbo. Vid närmare bekantskap kanske motviljan byts i fascination över getingarnas mästerliga byggnadskonst eller myrornas välordnade samhällen. Den röda skogsmyran med sina stora stackar är kanske den mest kända myran för de flesta, men vad många inte vet är att endast 16 av våra 81 arter myror bygger stackar. Bara honorna har gadd En av de viktigaste funktionerna med getingarnas gadd är att den gör det möjligt för dem att paralysera byten och att försvara boet. De solitära arterna måste kunna se till att den egna larven har färsk mat att tillgå medan den växer. Att lägga upp ett skyddat näringsförråd för den egna avkomman förutsätter att bytet inte är dött, bara paralyserat. De samhällsbyggande sociala arterna lever nästan uteslutande som rovdjur. De dödar sina byten som de sen matar sina larver med. På det sättet får larverna en proteinrik kost och kan växa snabbt.

A beautifully illustrated guide to the natural history and breathtaking diversity of spiders around the worldSpiders are dominant predators in virtually every terrestrial ecosystem on the planet. A marvel of evolution with species numbering in the tens of thousands, they have been walking the earth since before the dinosaurs. Spiders manipulate the silk strands of their webs to act as a sensory field, which vibrates across wide frequencies that they can read in detail, while young spiders spin silk lines that interact with the electrical fields in the atmosphere, enabling them to balloon across huge distances. Some spiders even gather in groups to impersonate ants in astonishing displays of collective mimicry. The Lives of Spiders explores these and other wonders, blending stunning imagery, lively writing, and the latest science to explore the natural history of the world’s diverse arachnid life.Features a wealth of color illustrationsSheds invaluable light on the life history, ecology, and stunning diversity of spidersCovers silk and web building, venoms, predators and prey, mating and dancing, spider cognition, and much moreDiscusses the impacts of human activity on spiders

Jürgen Tautz, renowned German bee researcher explains how bees communicate. Exciting and surprising new insights on communication between bees. During the history of bee research, scientists have peered deep into the inner life of bee colonies and learned much about the behaviour of these insects. Above all, the bee waggle dance has become a famous and extensively discussed phenomenon. Nevertheless, recent insights reveal that while bees are social insects inside the hive they also communicate with one another outside the hive. In this book, Jürgen Tautz, renowned German bee researcher, provides an entertaining, fresh and enlightened account for lay and professional readers, not only about the fascinating dance language but also about additional remarkable phenomena concerning information exchange between bees. From the author of the bestseller “The Buzz about Bees”. “The Language of Bees” assembles, for the first time, a complete overview of how bees understand one another. Although communication biology research on bees has so far concentrated largely on events within the hive, this book directs attention as well, to how bees communicate in the field outside the hive. The reader learns which steps new bee recruits take to reach the feeder a dancing forager has advertised. The book analyses the status of work on the bee dance published over the last 100 years and orders the essential findings as building blocks into a coherent new concept of how bees find their target. In addition, the historical survey of research on the “Bee Language” explains how several contradictory and incomplete hypotheses can still survive. A fresh point of view on one of the most remarkable behavioural performances in the animal kingdom. Observation from a different viewpoint leads to previously unknown insights. Such new perspectives clearly reveal both how large the gaps in our knowledge still are inrelation to the language of bees and in which direction research must take to complete the picture of one of the most impressive behavioural accomplishments in animals. Prof. Dr. Jürgen Tautz is an expert on bees, sociobiologist, animal behaviourist and emeritus professor at the Biozentrum, University of Würzburg. He is a bestseller author and recipient of many awards of excellence for his successful communication of science to a wide public.

To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica; in caves, under the ground, inside plants, other insects and vertebrates, in rivers, streams, lakes and ponds, in puddles, in the watery interiors of pitcher plants; and in our houses. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans.This Very Short Introduction explores the extraordinary world of insects. It analyses insect evolution, taxonomy and development, and describes their behaviour, their life styles, and the interactions they have with other insects and other animals. As Simon Leather shows, insects are the bedrock on which human civilisation rests; without them we would almost certainly not exist. Although they can be seen as pests of our crops plants, they are also invaluable for pollinating our flowering plants and are an invaluable link in all land ecosystems. As they face challenges from climate change and pesticides it has never been more important to understand these oft-dismissed creatures.Very Short Introductions: Brilliant, Sharp, Inspiring ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Långhorningar ståtar ofta med vackra färger, imponerande kroppsstorlek och synnerligen långa antenner. Därför har de ibland kallats just skalbaggsvärldens aristokrater. Det första mötet med en långhorning kan vara en minnesvärd upplevelse - som när en lång smaragdgrön myskbock flyger förbi framför näsan och med en duns landar på stugans faluröda panel. En del arter kan man artbestämma direkt på plats i naturen och de gör dem perfekta att "skåda" precis som fåglar och dagfjärilar. Namnet långhorningar kommer sig av att de flesta av dessa arter har långa antenner, ibland till och med längre än själva kroppen. Störst chans att få syn på en långhorning har du om du tittar i blommor där de äter pollen, eller på levande och döda träd där de ofta ses krypande. Många långhorningar är beroende av gamla och döda träd eftersom deras larver lever i ved och under bark, i vissa fall ända upp till tio år. Långhorningarna visar tydligt hur viktigt det är att bevara gammal skog. Bilderna i boken är gjorda med en speciell teknik där serier av fotografier med förflyttat skärpeplan monteras samman digitalt. Resultatet blir bilder med imponerande skärpedjup och tydliga detaljer.

Through its geographical position, varied topography, particular climate and complex cultural history, Romania has managed to sustain enormously rich biodiversity. Traditional practices, which have survived longer than in most other parts of Europe, have allowed the preservation of large areas of natural habitat, little altered by human activity. All this is reflected in the breadth of lepidoptera encountered in the country – from the dazzling Freyer’s Purple Emperor to the elusive Moorland Clouded Yellow, from the almost bird-like Great Banded Grayling to the diminutive Osiris Blue.This book considers all the species (and subspecies) of butterflies known to occur in Romania. This identification guide to the butterflies of Romania is set out in a format easy to understand not only by specialists but also for the more general naturalist or butterfly enthusiast. An expansive introduction covers the various life stages (ovum, larva, pupa and imago), biology and ecology, as well as protection and conservation, and butterfly research. The next section identifies the 14 most important habitat types frequented by butterflies in Romania.For each of the more than 200 species covered, information on taxonomy, identification, habitat, biology, conservation and distribution is presented. Each is illustrated with photographs from nature, primarily adult males and females, but also numerous images of the developmental stages. There follows a complete set of plates of prepared butterflies, displaying dorsal and ventral positions (upper and undersides) for both males and females. Finally, the male genital armature of several species are illustrated, primarily those difficult or impossible to identify using visual determination. The result is an attractive, practical and portable guide that not only helps identify the butterfly species of Romania, but also encourages the reader to more fully appreciate and protect them.

Honeybees make decisions collectively - and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, "Honeybee Democracy" brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees. In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together - as a swirling cloud of bees - to their new home.Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution. An impressive exploration of animal behavior, "Honeybee Democracy" shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

Dinosaurs, however toothy, did not rule the earth - and neither do humans. But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw - millions and millions of insects. Starting in the shallow oceans of ancient earth and ending in the far reaches of outer space - where, Shaw proposes, insect-like aliens might have achieved similar preeminence - Planet of the Bugs spins a sweeping account of insects' evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to global dominance.Through buggy tales at turns bizarre and comical - from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge - he not only unearths how changes in our planet's geology, flora, and fauna contributed to insects' success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to modern earth's hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how critical these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world's six-legged creatures, revealing an essential importance that resonates across time and space.

Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants possess defences that are effective against almost all herbivorous insect species. Host-plant specialization, observed in over 80% of these animals, appears to be an effective adaptation to breach these defence systems. The mechanisms underlying plant defence to invading herbivores on the one side, and insect adaptations to utilize plants for nutrition, defence and shelter on the other, are the main subjects of this book. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well. For insects, they include complex bevioural adaptations and their underlying sensory systems (with their implications for learning and nutritional plasticity), as well as the endocrinological aspects of life cycle synchronization with host-plant phenology.Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels and explicitly puts these in the context of both ecological interactions and evolutionary processes. In doing so, it uncovers the highly intricate antagonistic as well as mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production.This multidisciplinary approach will appeal to students in biology, agricultural entomology, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects.

Beekeeping is a sixteen-billion-dollar-a-year business. But the invaluable honey bee now faces severe threats from diseases, mites, pesticides, and overwork, not to mention the mysterious Colony Collapse Disorder, which causes seemingly healthy bees to abandon their hives en masse, never to return. In The Quest for the Perfect Hive, entomologist Gene Kritsky offers a concise, beautifully illustrated history of beekeeping, tracing the evolution of hive design from ancient Egypt to the present. Not simply a descriptive account, the book suggests that beekeeping's long history may in fact contain clues to help beekeepers fight the decline in honey bee numbers. Kritsky guides us through the progression from early mud-based horizontal hives to the ascent of the simple straw skep (the inverted basket which has been in use for over 1,500 years), from hive design's Golden Age in Victorian England up through the present. He discusses what worked, what did not, and what we have forgotten about past hives that might help counter the menace to beekeeping today. Indeed, while we have sequenced the honey bee genome and advanced our knowledge of the insects themselves, we still keep our bees in hives that have changed little during the past century. If beekeeping is to survive, Kritsky argues, we must start inventing again. We must find the perfect hive for our times. For thousands of years, the honey bee has been a vital part of human culture. The Quest for the Perfect Hive not only offers a colorful account of this long history, but also provides a guide for ensuring its continuation into the future.

This book is the first to allow you to experience the details of the ultra-fast lives of dragonflies, these large, beautiful flying insects, through an abundance of unique snapshots and image sequences. Dragonflies are world champions of flight, bionic wonders; they reveal much about the mysteries of evolution. We witness their social interaction, and appreciate their success over three hundred million years. Dragonflies - what an evocative name! - are easy to observe, even for beginners. About 80 species live in Germany, and every body of water is home to a few. They are not shy, do not sting and often come very close. Perhaps you will fall in love with dragonflies - just like the two authors who have been studying them for over 30 years. With the knowledge in this book, you will look at dragonflies in a completely novel way. About the AuthorsGeorg Rüppell was Professor of Behavioral Ecology at the Technical University of Braunschweig and has supervised over 300 studies with his working group, many of them on dragonflies. It was the quick-reaction training he got through his teenage sporting activities, he finds, that helped him to be constantly alert to the abrupt flight movements around him. He was the first biologist in the world to take up the field study of bird flight using slow-mo, and subsequently apply his expertise to dragonflies. He met his wife Dagmar Hilfert-Rüppell on a research trip to the dragonflies of Japan.Dagmar Hilfert-Rüppell has been studying and filming dragonflies for 30 years. She is particularly fond of damselflies, about which she wrote her doctoral thesis. She has developed infinite patience when filming to capture new behaviors in close-up. She is also the inspired driving force behind their numerous trips all around the world.
