In Caste and Ecology in the Social Insects, George F. Oster, an important contributor to the mathematical formulation of ideas regarding insect sociality, and Edward 0. Wilson, a long-time student of caste and social evolution in ants, have combined their consid- erable talents to attempt such a theory. They have The ergonomics of caste in the social insects 11.

According to the optimal theory (Oster & Wilson, 1978 ), such increases in reproductive output should be due to the specialized role that the nonreproductives Buy the Hardcover Book The Ergonomics of Caste in the Social Insects E O.

This work has been selected scholars as being culturally important, and is part of the knowledge base of civilization as we know it. The optimal caste allocation theory argues that specialized morphological castes are efficient at specific tasks, and hence different caste ratios should affect the ergonomic efficiency, hence reproduc-tive output of the colony. However, the reproductive output of different caste ratios has been documented in few species of insects with In many social species (if not most) caste is a result of undernourishment of the embryo through an extraction of nutriment from ripe eggs in the posterior (caudal) end of the ovariole. In species having many ovarioles, all ovulated eggs are worker-biased. Kin selection Social insect Introduction In the social Hymenoptera, the worker caste is entirely female and, like the queen caste, arises from fertilized, diploid eggs. With a few possible exceptions, the queen-worker dichotomy is non-genetic (Wilson 1971). Caste determination refers to Caste and Ecology in the Social Insects.

Social insects are an excellent system for addressing questions about epigenetics and evolution because: (1) they have dramatic caste polyphenisms that appear to be tied to differential methylation, (2) DNA methylation is widespread in various groups of social insects, and (3) there are intriguing connections between the social environment and The biology of social insects:proceedings of the Ninth Congress of the International Union for the Study of Social Insects, Boulder, Colorado, August 1982.

The Ergonomics of Caste in the Social Insects Created Date: 20160809015049Z In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects. Furthermore, in studying the effects of natural selection in generally increasing the insects' ergonomic efficiency, they go beyond the concentration of previous researchers on the 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. in Social Insects Nigel R.

Instead, task allocation in social insects occurs through distributed processes whose advantages, such as Past studies of caste systems in the social insects have focused on the ob- vious genetic and physiological problems of the mechanisms that control caste determination in the individual insect. Several independent experi- mental investigations have now provided a body of definitive information on the subject. Caste and Ecology in the Social Insects. Furthermore, in studying the effects of natural selection in generally increasing the insects' ergonomic efficiency, they go beyond the concentration of previous researchers on the physiological mechanisms of the insects and turn our attention instead to the scale and efficiency of the insects' division of labor. AbstractEusocial insects exhibit the most striking example of phenotypic plasticity. There has been a long controversy over the factors determining caste development of individuals in social insects. Here we demonstrate that parental phenotypes influence the social status of offspring not through genetic inheritance but through genomic imprinting in termites.

The social insects play a key role in the subject of sociobiology because their social organization is so rigid and can be related to genetic evolution. Because of this important consideration, the authors' work has consequences not only for entomology but also for general evolutionary theory.

The weight of workers belonging to a given caste at a given moment will increase in evolution according to the frequency and importance of the contingency to which it is specialized. 4. Under most, but not all, circumstances, it is of advantage to the colony progressively to increase the degree of specialization of each caste.
