In diesem Buch erfahren Sie, wie Ameisenvölker, die für ihr komplexes kollektives Verhalten bekannt sind, von Myrmecophilen infiltriert werden. Schmetterlinge, Fliegen, Käfer, Grillen, Spinnen, Pilze und Bakterien haben im Laufe ihrer Evolutionsgeschichte eine Vielfalt von Taktiken entwickelt, die sie befähigen, in Ameisenkolonien einzudringen und z.T. das Kommunikationssystem der Ameisen zu entschlüsseln. Einigen myrmecophilen Arten gelingt die Täuschung so gut, dass die Wirtsameisen die ungebetenen Gäste nicht mehr von wahren Nestgenossinnen unterscheiden können. Dieser spannende Vorgang wird von den Autoren detailliert beschrieben, um Ihnen zu erläutern, wie die Myrmecophilen den Code knacken und anschließend die Reserven der Kolonie ausbeuten. Bert Hölldobler und Christina Kwapich zeigen eine Vielzahl von Verhaltensmechanismen auf, mit denen Myrmecophile Ameisen zu „unfreiwilligen Dienern“ machen. Dieses Werk richtet sich sowohl an Fachleute als auch an Naturbegeisterte mit entsprechendem Vorwissen.

The Leafcutter Ants is the most detailed and authoritative description of any ant species ever produced. With a text suitable for both a lay and a scientific audience, the book provides an unforgettable tour of Earth's most evolved animal societies. Each colony of leafcutters contains as many as five million workers, all the daughters of a single queen that can live over a decade. A gigantic nest can stretch thirty feet across, rise five feet or more above the ground, and consist of hundreds of chambers that reach twenty-five feet below the ground surface. Indeed, the leafcutters have parlayed their instinctive civilization into a virtual domination of forest, grassland, and cropland—from Louisiana to Patagonia. Inspired by a section of the authors' acclaimed The Superorganism, this brilliantly illustrated work provides the ultimate explanation of what a social order with a half-billion years of animal evolution has achieved.

The Superorganism promises to be one of the most important scientific works published in this decade. Coming eighteen years after the publication of The Ants, this new volume expands our knowledge of the social insects (among them, ants, bees, wasps, and termites) and is based on remarkable research conducted mostly within the last two decades. These superorganisms—a tightly knit colony of individuals, formed by altruistic cooperation, complex communication, and division of labor—represent one of the basic stages of biological organization, midway between the organism and the entire species. The study of the superorganism, as the authors demonstrate, has led to important advances in our understanding of how the transitions between such levels have occurred in evolution and how life as a whole has progressed from simple to complex forms. Ultimately, this book provides a deep look into a part of the living world hitherto glimpsed by only a very few.

Diese von den beiden weltberühmten Experten geschriebene, reich illustrierte Naturgeschichte führt in die faszinierende Welt der Ameisen. Sie erfahren von der Artenvielfalt, von typischen Verhaltensweisen, von der effektiven Zusammenarbeit und den Verständigungsmöglichkeiten innerhalb der Kolonien und von den perfekt geplanten kämpferischen Auseinandersetzungen mit anderen Völkern. Die Autoren lassen Sie an der Spannung und dem Vergnügen teilhaben, welches sie bei ihrer Erforschung der Ameisen erlebt haben. Der Text wurde für die 2. deutsche Neuauflage von Bert Hölldobler auf den aktuellen Stand gebracht und umfangreich ergänzt. Zahlreiche zusätzliche neue Farbtafeln illustrieren die Welt der Ameisen noch beeindruckender. Diese 3. Auflage wurde gegenüber der Vorauflage noch einmal korrigiert. Die 1.Auflage wurde 1995 von bild der wissenschaft als Wissenschaftssachbuch des Jahres ausgezeichnet.

A fascinating examination of socially parasitic invaders, from butterflies to bacteria, that survive and thrive by exploiting the communication systems of ant colonies.Down below, on sidewalks, in fallen leaves, and across the forest floor, a covert invasion is taking place. Ant colonies, revered and studied for their complex collective behaviors, are being infiltrated by tiny organisms called myrmecophiles. Using incredibly sophisticated tactics, various species of butterflies, beetles, crickets, spiders, fungi, and bacteria insert themselves into ant colonies and decode the colonies’ communication system. Once able to “speak the language,” these outsiders can masquerade as ants. Suddenly colony members can no longer distinguish friend from foe.Pulitzer Prize–winning author and biologist Bert Hölldobler and behavioral ecologist Christina L. Kwapich explore this remarkable phenomenon, showing how myrmecophiles manage their feat of code-breaking and go on to exploit colony resources. Some myrmecophiles slip themselves into their hosts’ food sharing system, stealing liquid nutrition normally exchanged between ant nestmates. Other intruders use specialized organs and glandular secretions to entice ants or calm their aggression. Guiding readers through key experiments and observations, Hölldobler and Kwapich reveal a universe of behavioral mechanisms by which myrmecophiles turn ants into unwilling servants.As The Guests of Ants makes clear, symbiosis in ant societies can sometimes be mutualistic, but, in most cases, these foreign intruders exhibit amazingly diverse modes of parasitism. Like other unwelcome guests, many of these myrmecophiles both disrupt and depend on their host, making for an uneasy coexistence that nonetheless plays an important role in the balance of nature.

This landmark work, the distillation of a lifetime of research by the world’s leading myrmecologists, is a thoroughgoing survey of one of the largest and most diverse groups of animals on the planet. Bert Hölldobler and Edward O. Wilson review in exhaustive detail virtually all topics in the anatomy, physiology, social organization, ecology, and natural history of the ants. In large format, with almost a thousand line drawings, photographs, and paintings, it is one of the most visually rich and all-encompassing views of any group of organisms on earth. It will be welcomed both as an introduction to the subject and as an encyclopedia reference for researchers in entomology, ecology, and sociobiology.

Asked to name an insect society, most of us--whether casual or professional students of nature--quickly point to one of the so-called eusocial marvels: the ant colony, the beehive, the termite mound, the wasp nest. Each is awe-inspiring in its division of labor--collective defense, foraging, and nestbuilding. Yet E. O. Wilson cautioned back in 1971 that sociality should be defined more broadly, "in order to prevent the arbitrary exclusion of many interesting phenomena." Thirty-five years later, James T. Costa gives those interesting phenomena their due. He argues that, in trying to solve the puzzle of how highly eusocial behaviors evolved in a few insect orders, evolutionary biologists have neglected the more diverse social arrangements in the remaining twenty-eight orders--insect societies that don't fit the eusocial schema. Costa synthesizes here for the first time the scattered literature about social phenomena across the arthropod phylum: beetles and bugs, caterpillars and cockroaches, mantids and membracids, sawflies and spiders. This wide-ranging tour takes a rich narrative approach that interweaves theory and data analysis with the behavior and ecology of these remarkable groups. This comprehensive treatment is likely to inspire a new generation of naturalists to take a closer look.
