The Ecology of Altruism in a Clonal Insect,lity for several reasons: (1) Since aphids are clonal, the genetics of a colony is starkly simple (the aphids are either from the same clone or they are not) and, in principle, easy to measure; (2) Because good phylogeni es are available for several aphid taxa and there is clear evidence that there

Why are so Many Bees but so Few Digger Wasps Social? The Effect of Provisioning Mode and Helper Effersity of social life forms, eusocial species are very unevenly distributed among different families. Here we ask why within the superfamily Apoidea so few sphecid wasps but so many bees have become eusocial. We argue that the crucial difference between these two taxa is the type of resource provide

Social Plasticity: Ecology, Genetics, and the Structure of Ant Societies,ker caste s and altruistic behavior in ants, bees, and wasps. Much research has therefore concentrated on elucidating the genetic structure of Hymenopteran societies. However, variation in kinship appears to be surprisingly unimportant in shaping some of the details of the social structure of insect

The Ecology of Social Evolution in Termites,te ants’. However, the termites evolved social life independently, long before the ants. Their different ancestry also is reflected in several fundamental differences in the organization of the colonies. This chapter aims at summarizing the state-of-the-art in termite research and comparing the resu

Kin-Recognition Mechanisms in Cooperative Breeding Systems: Ecological Causes and Behavioral Conseqates, helpers assist relatives. However, whether help is directed towards kin through an active kin-selection process or whether it is merely the result of passive coincidence, i.e., because the helpers normally remain on the natal territory where the recipients of help just happen to be relatives h
