Synchronized maturation and breeding in natural populations of , (Poeciliidae),ime. This coordinate development has also been seen in the laboratory. We hypothesize that juveniles resembling each other experience fewer aggressive responses from males than do juveniles without ‘look-alikes’, because of habituation of aggression. This would decrease social inhibition and permit

Maintenance of female mimicry as a reproductive strategy in bluegill sunfish (,),reduction in male reproductive effort, sometimes occur. Female mimicry in bluegill sunfish (.) is an example of an obligate alternative male strategy. Female mimics are small, sexually mature males which mimic the details of female behavior, and gain access to functional females attracted to the nes

For large species (> 100 mm SL) and widely separated patches, numerous propagules are needed, often with specialized pelagic intervals. Individuals of small species are confined to portions of the reef. They are unable to produce enough eggs for effective long-range dispersal, and so th

The greater organization in school structure appears to be an adaptive response to aquatic predators, whereas increased cover seeking may be an adaptive response to aerial predators.
