Queen control of sex ratio in fire ants.
The haplodiploid sex-determination system of ants gives rise to conflict between queens and workers over colony sex ratios, and the female-biased allocation ratios seen in many species suggest that workers often prevail in this conflict. We exchanged queens between male- and female-specialist colonies of the fire ant Solenopsis invicta. These exchanges quickly reversed the sex-ratio biases of a...
متن کاملWeb Sessions Clustering with Artificial Ants Colonies
In this paper, we present AntClust, an ant based clustering algorithm and its application to the Web usage mining problem. We define a Web session as a weighted multi-modal vector and we also develop a similarity measure between two sessions. We show that the partitions found by AntClust are stable on a data set made of real sessions extracted from a Web site of the University of Tours. Contrar...
متن کاملEvolution of social parasitism in ants: size of sexuals, sex ratio and mechanisms of caste determination
Social parasitism, one of the most intriguing phenomena in ants, has evolved to various levels, the most extreme form being parasites that have lost the worker caste and rely completely on the host's worker force to raise their brood. A remarkable feature of workerless social parasites is the small size of sexuals. It has been suggested that reduced size evolved as a means to take advantage of ...
متن کاملPrimary sex ratio regulation by queens in ants (Formicidae) and other social Hymeno- ptera
Sex allocation theory describes how parents should bias investment in either sons or daughters when each gives a different fitness return. Over the past decades, social Hymenoptera have increasingly been used as models for testing the predictions of sex ratio theory. Their haplodiploid sex determining system gives mothers considerable control over the proportion of each offspring sex by selecti...
متن کاملSex Ratio Elasticity Influences the Selection of Sex Ratio Strategy
There are three sex ratio strategies (SRS) in nature-male-biased sex ratio, female-biased sex ratio and, equal sex ratio. It was R. A. Fisher who first explained why most species in nature display a sex ratio of ½. Consequent SRS theories such as Hamilton's local mate competition (LMC) and Clark's local resource competition (LRC) separately explained the observed deviations from the seemingly u...
