The incredible global diversity of ants, and their important ecological roles, mean that we cannot ignore the significance of ants in ecological systems. Ant Ecology takes the reader on a journey of discovery from the beginnings of ants many hundreds of thousands of years ago, through to the makings of present day distributions.
This book is concerned with two problems: how eusociality, in which one individual forgoes reproduction to enhance the reproduction of a nestmate, could evolve under natural selection, and why it is found only in some insects-termites, ants and some bees and wasps. Although eusociality is apparently confined to insects, it has evolved a number of times in a single order of insects, the Hymenoptera. W. Hamilton's hypothesis, that the unusual haplodiploid mechanism of sex determination in the Hymenoptera singled this order out, still seems to have great explanatory power in the study of social ants. We believe that the direction, indeed confinement, of social altruism to close kin is the mainspring of social life in an ant colony, and the alternative explanatory schemes of, for example, parental manipu lation, should rightly be seen to operate within a system based on the selective support of kin. To control the flow of resources within their colony all its members resort to manipulations of their nestmates: parental manipulation of offspring is only one facet of a complex web of manipul ation, exploitation and competition for resources within the colony. The political intrigues extend outside the bounds of the colony, to insects and plants which have mutualistic relations with ants. In eusociality some individuals (sterile workers) do not pass their genes to a new generation directly. Instead, they tend the offspring of a close relation (in the simplest case their mother).
Wood ants play an ecologically dominant and conspicuous role in temperate boreal forests, making a keystone contribution to woodland ecosystem functions and processes. Wood ant taxonomy and global distributions set the scene for this text's exploration of wood ants as social insects, examining their flexible social structures, genetics, population ecology, and behaviour, from nest-mate recognition to task allocation. Wood ants' interactions with their environment and with other organisms are essential to their success: competition, predation and mutualism are described and analysed. Bringing together the expertise of ecological researchers and conservation practitioners, this book provides practical and theoretical advice about sampling and monitoring these insects, and outlines the requirements for effective conservation. This is an indispensable resource for wood ant researchers, entomologists, conservationists and ecological consultants, as well as anyone interested in social insects, keystone species and the management and conservation of forest ecosystems.
This important work explores the natural history, experimental approach, and integration of evolutionary and ecological literature of ant-plant mutualisms.
Ants that commonly invade homes, damage structures, inflict painful bites, or sting humans or their pets are considered pest ants. This illustrated identification guide highlights forty species of ants that pose difficulties in urban settings. Included are well-known invasive troublemakers such as the red imported fire ant and Argentine ant, as well as native species. After an introductory chapter on the evolution, biology, and ecology of pest ants, the book follows a taxonomic arrangement by subfamily. Each subfamily chapter includes separate illustrated keys to both the genera and species of that group to enable entomologists and pest control professionals to identify pest ants correctly. The species accounts cover biology, distribution, and methods for excluding and/or removing ants from human structures and landscapes. The authors focus on the ants' biology and nesting behavior, life cycles, and feeding preferences; an intimate understanding of these factors enables the implementation of the least toxic control methods available. A chapter on control principles and techniques encompasses chemical strategies, habitat and structural modifications, biological control, and integrated pest management methods. Urban Ants of North America and Europe also contains valuable information on the diagnosis and treatment of human reactions to ant stings and bites. This comprehensive reference work on these economically significant ants includes the scientific, English, French, Spanish, and German names for each species and a summary of invasive ant species in the United States and Europe.
From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna. TOC:The importance of ants.- Classification and origins.- The colony life cycle.- Altruism and the origin of the worker caste.- Colony odor and kin recognition.- Queen numbers and domination.- Communication.- Caste and division of labor.- Social homeostasis and flexibility.- Foraging and territorial strategies.- The organization of species communities.- Symbioses among ant species.- Symbioses with other animals.- Interaction with plants.- The specialized predators.- The army ants.- The fungus growers.- The harvesters.- The weaver ants.- Collecting and culturing ants.- Glossary.- Bibliography.- Index.
This book is the first user-friendly regional guide devoted to ants—the “little things that run the world.” Lavishly illustrated with more than 500 line drawings, 300-plus photographs, and regional distribution maps as composite illustrations for every species, this guide will introduce amateur and professional naturalists and biologists, teachers and students, and environmental managers and pest-control professionals to more than 140 ant species found in the northeastern United States and eastern Canada. The detailed drawings and species descriptions, together with the high-magnification photographs, will allow anyone to identify and learn about ants and their diversity, ecology, life histories, and beauty. In addition, the book includes sections on collecting ants, ant ecology and evolution, natural history, and patterns of geographic distribution and diversity to help readers gain a greater understanding and appreciation of ants.
Countless ants transport and deposit seeds and thereby influence the survival, death, and evolution of many plant species. In higher plants, seed dispersal by ants (myrmecochory) has appeared many times independently in different lineages. More than 3000 plant species are known to utilize ant assistance to be planted. Myrmecochory is a very interesting and rather enigmatic form of mutualistic ant-plant associations. This phenomenon is extremely complex, because there are hundreds of ant species connected with hundreds of plant species. This book effectively combines a thorough approach to investigating morphological and physiological adaptations of plants with elegant field experiments on the behaviour of ants. This monograph is a first attempt at collecting information about morphology, ecology and phenology of ants and plants from one ecosystem. The book gives readers a panoramic view of the hidden, poorly-known interrelations not only between pairs of ants and plant species, but also between species communities in the ecosystem. The authors have considered not just one aspect of animal-plant relationships, but have tried to show them in all their complexity. Some aspects of the ant-plant interactions described in the book may be of interest to botanists, others to zoologists or ecologists, but the entire work is an excellent example of the marriage of these biological disciplines.
