Parasites in Social Insects


Book Description

This book analyzes for the first time how parasites shape the biology of social insects: the ants, wasps, bees, and termites. Paul Schmid-Hempel provides an overview of the existing knowledge of parasites in social insects. Current ideas are evaluated using a broad database, and the role of parasites for the evolution and maintenance of the social organization and biology of insects is carefully scrutinized. In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts. Schmid-Hempel identifies gaps in our knowledge about parasites in social insects and uses models to develop new questions for future research. In addition, issues that are usually considered separately--such as division of labor, genetics, immunology, and epidemiology--are placed in a common framework to analyze two of the most successful adaptations of life: parasitism and sociality. This work will appeal not only to practitioners in the fields of behavioral ecology and sociobiology, but also to others interested in host-parasite relationships or in social organisms, such as apiculturists struggling to overcome the problems arising from mite infestations of honeybee colonies.




Host Manipulation by Parasites


Book Description

Parasites that manipulate the behaviour of their hosts represent striking examples of adaptation by natural selection. This text provides an authoritative review of host manipulation by parasites that assesses developments in the field and lays out a framework for future research.

The Social Insects


Book Description

Originally published in 1928, this volume, by a world authority on the subject, sums up our knowledge of the social insects. It inquires what are the social insects and what it is that makes us call them ‘social’. Terebrantia, aculeata, wasps, bees, ants, and termites are discussed in a succession of chapters, showing how they have evolved, to how great an extent they have developed, and what are the peculiarities of their evolution. Polymorphism, the Social Medium, Guests and Parasites of the Social Insects, are other subjects discussed in this fascinating book.




The Evolution and Fossil Record of Parasitism


Book Description

This two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume one focuses on identifying parasitism in the fossil record, and sheds light on the distribution and ecological importance of parasite-host interactions over time. In order to better understand the evolutionary history of parasites and their relationship with changes in the environment, emphasis is given to viruses, bacteria, protists and multicellular eukaryotes as parasites. Particular attention is given to fungi and metazoans such as bivalves, cnidarians, crustaceans, gastropods, helminths, insects, mites and ticks as parasites. Researchers, specifically evolutionary (paleo)biologists and parasitologists, interested in the evolutionary history of parasite-host interactions as well as students studying parasitism will find this book appealing.




The Biology Of Social Insects


Book Description

In this book internationally known experts provide a comprehensive view of current knowledge of social insect biology including much previously unpublished information. Particular emphasis is given to the relationships between social insects and humans; sections are devoted to economically important social insects, pollination, foraging, and the role of insects in ecosystems and agroecosystems. The authors also discuss communication, behavior and caste within insect colonies. A special section focuses on the neurobiology of social insects. A series of papers considers the presocial insects, which live in family groups but without caste differences. Also well represented are the fields of sociobiology and the origins and evolution of social behavior. The book will be valuable to agricultural scientists as well as to entomologists, sociobiologists, ecologists, ethologists, and natural historians. Endocrinologists and neurobiologists will also find important new material.




Social Insects as Solitary Vehicles


Book Description

Parasite-host interactions affect more than the two main characters. Organisms living in tight-knit communities depend on each other in order to survive. Individuals harboring a parasite can affect the delicate balance within these communities. While on the other hand the community could also have a strong effect on a parasites life cycle. I explore the effects infected individuals have on the within-nest dynamics of ant colonies. Additionally, I investigate the effects of infectious and non-infectious cadaver exposure have on worker behavior, as well as determine the effects workers have on the fungus protruding from the infectious cadavers. Using both a coevolved fungus, Ophiocordyceps unilateralis sensus lato, and a generalist fungus, Beauveria bassiana, I found infected workers do not strongly affect the within nest dynamics of Camponotus castaneus, the natural host of O. unilateralis s. l. Furthermore C. castaneus and C. pennsylvanicus manage infectious and non-infectious cadavers differently. Workers from C. castaneus colonies are adept in quickly removing cadavers with internal and external fungal development. While C. pennsylvanicus workers must come in contact with fungal tissue in order to recognize the disease threat. However, I found C. pennsylvanicus workers to be highly effective in reducing the infectivity of hazardous fungal conidia (i.e. asexual spores). Such findings could be caused by the wood nesting ecology this species has, as well as the higher aggression towards infectious cadavers. My research lays the foundation for future studies which focus on using semi-natural settings to study parasite-host and community dynamics.




Social Insects


Book Description

Here is a guide to the ecology of social insects. It is intended for general ecologists and entomologists as well as for undergraduates and those about to start research on social insects; even the experienced investigator may find the comparison between different groups of social insects illuminating. Most technical terms are translated into common language as far as can be done without loss of accuracy but scientific names are unavoidable. Readers will become familiar with the name even though they cannot visualize the animal and could reflect that only a very few of the total species have been studied so far! References too are essential and with these it should be possible to travel more deeply into the vast research literature, still increasing monthly. When I have cited an author in another author's paper, this implies that I have not read the original and the second author must take responsi bility for accuracy! Many hands and heads have helped to make this book. I thank all my colleagues past and present for their enduring though critical support, and I thank with special pleasure: E. ]. M. Evesham who fashioned the diagrams; ]. Free, D. J. Stradling and]. P. E. C. Darlington who supplied photographs; D. Y. Brian and R. A. Weller who were meticulous on the linguistic side; and G. Frith and R. M. Jones who collated the references. List of plates 1. Fungus combs of Acromyrmex octospinosus and Macrotermes michaelseni. 13 2. Mouthparts of larval Myrmica.




Great Adaptations


Book Description

"The irresistible enthusiasm of Great Adaptations couldn’t come at a better time."—David P. Barash, Wall Street Journal "Be very amazed."—Carl Safina, author of Beyond Words and Becoming Wild How one scientist unlocked the secrets behind some of nature’s most astounding animals From star-nosed moles that have super-sensing snouts to electric eels that paralyze their prey, animals possess unique and extraordinary abilities. In Great Adaptations, Kenneth Catania presents an entertaining and engaging look at some of nature’s most remarkable creatures. Telling the story of his biological detective work, Catania sheds light on the mysteries behind the behaviors of tentacled snakes, tiny shrews, zombie-making wasps, and more. He shows not only how studying these animals can provide deep insights into how life evolved, but also how scientific discovery can be filled with adventure and fun. Beginning with the star-nosed mole, Catania reveals what the creature’s nasal star is actually for, and what this tells us about how brains work. He explores how the deceptive hunting strategy of tentacled snakes leads prey straight to their mouths, how eels use electricity to control other animals, and why emerald jewel wasps make zombies out of cockroaches. He also solves the enigma of worm grunting—a traditional technique in which earthworms are enticed out of the ground—by teaming up with professional worm grunters. Catania demonstrates the merits of approaching science with an open mind, considers the role played by citizen scientists, and illustrates that most animals have incredible, hidden abilities that defy our imagination. Examining some strange and spectacular creatures, Great Adaptations offers a wondrous journey into nature’s grand designs.
