This work is a brief review of a series of studies of the phenotypic organization and ecological significance of individual differences in fish behavior. The following species were studied: guppy Poecilia retuculata, lion-headed cichlid Steatocranus cassuarius, and the convict cichlid Archocentrus nigrofasciatum. We developed methods for the analysis of individual differences in fish behavior a...

I examined the relation between courtship and mate choice in convict cichlids by presenting females with the option of courting and spawning with one of two males that were isolated from each other. I quantified the amount of courtship performed by females towards males they selected as mates and males they rejected, and the amount of courtship performed by each male towards the female. I measu...

Analyses of nationally representative survey data show that younger, left-leaning, working class Australians are most likely to identify as convict descendants, while older, high income, educat...

Aggressive behavior can be an important factor in determining how animals use and divide space and resources. Previous studies have shown that aggression in fishes can be influenced by a variety of factors, including water temperature and resource levels. In this study, we tested if the amount of habitat structure in the environment affected aggression levels in female convict cichlids Archocen...

Sir,?Major YVoolley's excellent article on Convict marriages in the Andamans in your March number does not appear to have aroused the comment?favourable or the reverse?which I anticipated and which it deserved. It is, however, of great interest to all those who have at heart the improvement of the criminal in the present and his disappearance in the future. As lie says, it is rather a shock to ...
