A world-renowned researcher of animal behavior reveals the extraordinary orienteering skills of desert ants, offering a thrilling account of the sophisticated ways insects function in their natural environments.
Cataglyphis desert ants are agile ultrarunners who can tolerate near-lethal temperatures when they forage in the hot midday sun. But it is their remarkable navigational abilities that make these ants so fascinating to study. Whether in the Sahara or its ecological equivalents in the Namib Desert and Australian Outback, the Cataglyphis navigators can set out foraging across vast expanses of desert terrain in search of prey, and then find the shortest way home. For almost half a century, Rüdiger Wehner and his collaborators have devised elegant experiments to unmask how they do it.
Through a lively and lucid narrative, Desert Navigator offers a firsthand look at the extraordinary navigational skills of these charismatic desert dwellers and the experiments that revealed how they strategize and solve complex problems. Wehner and his team discovered that these insect navigators use visual cues in the sky that humans are unable to see, the Earth’s magnetic field, wind direction, a step counter, and panoramic “snapshots” of landmarks, among other resources. The ants combine all of this information to steer an optimal course. At any given time during their long journey, they know exactly where to go. It is no wonder these nimble and versatile creatures have become models in the study of animal navigation.
Desert Navigator brings to light the marvelous capacity and complexity found in these remarkable insects and shows us how mini brains can solve mega tasks.
Ants are probably the most dominant insect group on Earth, representing ten to fifteen percent of animal biomass in terrestrial ecosystems. Flowering plants, meanwhile, owe their evolutionary success to an array of interspecific interactions—such as pollination, seed dispersal, and herbivory—that have helped to shape their great diversity. The Ecology and Evolution of Ant-Plant Interactions brings together findings from the scientific literature on the coevolution of ants and plants to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and ultimately of terrestrial biological communities.
The Ecology and Evolution of Ant-Plant Interactions synthesizes the dynamics of ant-plant interactions, including the sources of variation in their outcomes. Victor Rico-Gray and Paulo S. Oliveira capture both the emerging appreciation of the importance of these interactions within ecosystems and the developing approaches that place studies of these interactions into a broader ecological and evolutionary context. The collaboration of two internationally renowned scientists, The Ecology and Evolution of Ant-Plant Interactions will become a standard reference for understanding the complex interactions between these two taxa.
From subarctic tundra to equatorial rainforest, deep in the soil and at the tip of the highest tree, ants are found the world over. This book, by the world’s leading ant taxonomist, offers a definitive guide for identifying these ubiquitous insects.
Barry Bolton provides identification keys to all the living ant subfamilies and genera, presented in alphabetical order and separated by zoogeographical region. Designed for professional and amateur myrmecologists alike, this guide is as accessible as it is comprehensive, including information on the function and use of identification keys, instructions for preparing specimens for examination, and an illustrated glossary of morphological terms. Over 500 scanning electron microscope photographs illustrate the taxonomic keys.
Bolton introduces each subfamily with a diagnosis of the group, followed by synoptic classifications of all genera within each subfamily, notes on broad distribution, and a list of references to all species-rank publications useful to identification. He also provides a short summary of the extinct subfamilies and includes a checklist of every name ever proposed in the classification of ants, from the rank of family down to subgenus, showing the current status and usage of each.
An updated and exhaustively expanded revision of the taxonomic keys found in Hölldobler and Wilson’s The Ants, Bolton’s identification guide takes its place alongside that landmark work as the foundation for the study of ants for many years to come.
“A name is forever, or at least as long as taxonomy continues,” Barry Bolton writes, and here are all the names, antique and modern, of all the ants that are or ever were—from the arctic to the tropical, the fossilized to the living, the mislabeled to the newly christened members of the family Formicidae. For every name that has ever been applied to ants, the book supplies a history and an account of current usage, together with a fully documented indication of the present-day classification. Its comprehensive bibliography provides references to original description, synonymy, homonymy, changes in rank, status, and availability, and alterations in generic status.
Organized by family group, genus group, and species group, this meticulously detailed but easily used volume is the ultimate resource for myrmecology. Along with Bolton’s Identification Guide to the Ant Genera of the World, it will be the essential reference for anyone, expert or amateur, with an interest in ants.
