Abstract

Since their discovery in 1932, all-female ''species'' of fish have provided rich material for ecological and evolutionary studies. The significance of these rare organisms lies in the perspective they provide on what is considered normal (i.e. biparental sexuality). Study of these fish and their sexual relatives has contributed to our understanding of: (i) the origins and evolution of asexuality; (ii) the ecology ofhybrids; (iii) genotypic and environmental effects on ecologically relevant traits; and (iv) the maintenance of sex in higher organisms. A consistent message emerging from these studies is the significance of genetic diversity for survival in spatially and temporally heterogeneous environments. Consequently, unisexual fish also serve as useful models for studying the role of genetic variation in the survival of small endangered populations. Finally, unisexual fish serve as geneticallyuniform systems for environmental and biomedical studies. The purposeof this review is to bring wider attention to the range of biologicalproblems that can be attacked with these remarkable organisms.
