Monogamy and sex change by aggressive dominance in coral reef fish

  title={Monogamy and sex change by aggressive dominance in coral reef fish},
  author={Hans W. Fricke and Simone Fricke},
IN several sequentially hermaphroditic coral reef fish, of which individuals first function as females and then males (protogynous hermaphroditism), dominant males can control production of other males by aggressive dominance over females1–4. Robertson suggested that socially controlled protogynous sex changes might operate only in species with a well defined polygynous social system “based on individual relationships”2,3. Further exogenous and endogenous factors may control sex change in… 
Why is bidirectional sex change rare?
The model can explain why species show unidirectional sex change, in that an individual's switch to a new sex is irreversible, even if the individual's social situation returns to the original subdominant status.
Size, maturation and the social control of sex reversal in the coral reef fish Anthais squamipinnis
Gonadal histology on 130 specimens confirmed that this species is a monandric, protogynous hermaphrodite and provided details of gonadal transformation, showing that sex reversals resulted from male removals and were not coincidental, ongoing events.
Alternative Contexts of Sex Change with Social Control in the Bucktooth Parrotfish, Sparisoma radians
Alternative contexts of sex change are shown, with sex change occurring within social groups in some locations and with bachelor males filling harem vacancies in other locations, to illustrate the astonishing phenotypic plasticity in the social and mating behavior of parrotfishes.
Reversed sex-change in the protogynous reef fish Labroides dimidiatus
The sex of L. dimidiatus is strictly determined by social status whenever it changes after mate loss, and the first report of reversed sex-change among protogynous wrasses is reported.
Control of different mating systems in a coral reef fish by one environmental factor
The experimental alteration of coral sizes resulted in an increase of male numbers, in artificially composed groups, with the increase of coral size, and pairs and harems were produced on small corals, multimale groups on big corals.
Male-to-female sex change in widowed males of the protogynous damselfish Dascyllus aruanus
Experiments to make male/female-only groups in the protogynous humbug damselfish Dascyllus aruanus, living on branching-type corals under low-density conditions found the smaller of the widowed males on an isolated coral head changed sex to female when no females or juveniles immigrated onto the coral.
Social Behavior of Males and Simultaneous Hermaphrodites in the Lantern Bass
The behavior patterns found in the serranines reflect the differences in mating systems in a manner similar to that found in other organisms and is consistent with current mating system theory.
Behavioural changes of protogynous sex reversal in a coral reef fish in the laboratory
Abstract In the group-living, protogynous coral reef fish Anthias squamipinnis (Peters), males differed from females behaviourally by performing and reveiving five movement patterns at different
Female-mediated causes and consequences of status change in a social fish
This study examined male reproductive anatomy, physiology and behaviour following experimental manipulations of social status in the cooperatively breeding cichlid fish, Neolamprologus pulcher, and highlighted the complex interactions between social status, reproductive physiology and group dynamics.
Intragroup behavioural changes and the initiation of sex reversal in a coral reef fish in the laboratory
Abstract Observations of the coral reef fish Anthias squamipinnis (Peters) suggest that the behavioural control of female-to-male sex reversal is more complex than a simple dependence on the presence


Social Control of Sex Reversal in a Coral-Reef Fish
Males of Labroides dimidiatus control the process of sex reversal within social groups by actively dominating them and death of the male releases this suppression and the dominant female of the harem changes sex immediately.
Sex change and sexual selection
Giselin (2) shifted the focus by suggesting that if members of one sex increase in fertility more rapidly with age than those of the other, then natural selection will favor a genotype whose individuals are all born into the sex that suffers less from being young.
Protogynous Sex Reversal in the Fish Anthias squamipinnis (Teleostei, Anthiidae) regulated by the Presence or Absence of a Male Fish
To establish whether environmental factors regulate this sex reversal, or if it is a continuous and non-predictable process, a series of experiments with Anthias performed in captivity during 1968 and 1969 found no change in morphology or behaviour to indicate sex change.
