Sex change in marine teleost fishes is commonly regulated by social factors. In species that exhibit protogynous sex change, such as the bluebanded goby Lythrypnus dalli, the most dominant female typically initiates sex change when a male is removed from the social group. Females can use visual, chemical or tactile cues to assess the presence or absence of a male. The primary goal of our study was to determine whether the olfactory and visual presence of a male versus its behavioural… Expand

Social status determines sexual phenotype in the bi‐directional sex changing bluebanded goby Lythrypnus dalli
TLDR
It is demonstrated that similar mechanisms underlie sex change in both directions in L. dalli and potentially other sex changing species. Expand
Sexual Plasticity in a Marine Goby (Lythrypnus dalli): Social, Endocrine, and Genetic Influe nces on Functional Sex
TLDR
An evolutionary mechanism in sexually plastic species is suggested that has linked the conserved molecular cascades of sexual differentiation to a novel signal that varies over life history, social status, thereby allowing for lifelong phenotypic plasticity. Expand
Female, but not male, agonistic behaviour is associated with male reproductive success in stable bluebanded goby (Lythrypnus dalli) hierarchies
TLDR
Ass associations between agonistic behaviour and male reproductive success in stable social groups of bluebanded gobies (Lythrypnus dalli) are described, showing that there was a significant, negative association betweenmale reproductive success and the total rate agonistic interactions by a group. Expand
The goby Lythrypnus pulchellus is a bi-directional sex changer
TLDR
It is demonstrated that Lythrypnus pulchellus, a small cryptobenthic haremic reef fish, is a bi-directional sex changer, at least in experimental conditions, and the results support the idea that extreme sexual plasticity is a widespread reproductive trait in the genus Lythypnus. Expand
Growth acceleration, behaviour and otolith check marks associated with sex change in the wrasse Halichoeres miniatus
TLDR
An increase in growth rate is a regular feature of sex-change dynamics of H. miniatus, indicating that new sex-changed males may be able to rapidly reach a size where they can defend the remaining harem from other males. Expand
The Causes and Consequences of Variation in Agonistic Behavior in the Bluebanded Goby (Lythrypnus dalli)
TLDR
Together, these studies provide a comprehensive look at the social, reproductive, and neuroendocrine factors associated with individual variation in agonistic behavior and empirically-based predictions about the fitness consequences. Expand
Serotonin, social status and sex change in the bluebanded goby Lythrypnus dalli
TLDR
Interestingly, the sex changing fish Lythrypnus dalli does not seem to fit the pattern seen in other vertebrates where dominant individuals have lower serotonergic activity than subordinates, and its effect on dominance status is unclear. Expand
Reproductive behaviors and sex roles during a diurnal cycle of the goby, Lythrypnus pulchellus (Teleostei: Gobiidae)
TLDR
The frequencies and durations of reproductive behaviors of both males and females decreased according to time of day in both biased sex ratio experiments, except for the courtship behaviors ‘Nest approach’ in females and “Nest defense” in males that increases throughout the day. Expand
Crepidula Slipper Limpets Alter Sex Change in Response to Physical Contact with Conspecifics
TLDR
The results suggest that the cue that affects size and time to sex change requires some kind of physical interaction that is lost when the snails are separated, and contact with another snail’s pedal mucus does not compensate for the loss of physical contact. Expand
Differing Mechanisms Underlie Sexual Size-Dimorphism in Two Populations of a Sex-Changing Fish
TLDR
This study demonstrates that previous growth history and growth rate changes associated with sex change can be responsible for the sexual dimorphism typically found in sex-changing species, and that the relative importance of these may be socially constrained. Expand

Social faciliation and sensory mediation of adult sex change in a cryptic, benthic marine goby
TLDR
While sensory cues mediated the timing of sex change, other factors (probably social) likely played a part in determining which individuals within the social group actually changed sex. Expand
An integrative approach to sex change: social, behavioural and neurochemical changes in Lythrypnus dalli (Pisces)
Abstract. This study examined three aspects of protogynous sex change in Lythrypnus dalli (Gobiidae): (1) social influences on the rate of sex change, (2) the sequence of behavioural changes, and (3)Expand

TLDR
Testing the hypothesis that adult female-to-male sex reversal in protogynous fish is induced by the loss of close-contact behavioral interactions between males and females found that sex change is apparently induced by loss of male-female behavioral interaction in combination with continued interaction between females. Expand
Social Control of Sex Change in the Bluehead Wrasse, Thalassoma bifasciatum (Pisces: Labridae).
TLDR
It is shown that removal of large terminal color phase males from local populations leads to sex and color change in the largest initial color phase females, and that mature sperm can be produced in as little as eight days after the initiation of sex change. Expand
Sex Reversal in Pairs of Lythrypnus dalli: Behavioral and Morphological Changes
TLDR
It is found that pairs of L. dalli females quickly and readily form stable dominance relationships, with the dominant fish changing sex into a male, providing excellent opportunities to examine the early behavioral and morphological changes associated with dominance and sex change. Expand
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 presenceExpand
Reproduction in context: Field testing a laboratory model of socially controlled sex change in Lythrypnus
TLDR
To induce sex change of L. dalli in a more natural environment and compare field dynamics with the laboratory-based model, groups of Lythrypnus dalli, composed of one large male and three females of varying sizes, were introduced into artificial habitats in the field. Expand
Experimental test of socially mediated sex change in a protandric simultaneous hermaphrodite, the marine shrimp Lysmata wurdemanni (Caridea: Hippolytidae)
TLDR
The number and complexity of social interactions in large groups may be necessary to stimulate labile sex change in this species and size-ratio induction of sex change by small MPs was suggested but not confirmed. Expand
Social control of sex change in the shelf limpet, Crepidula norrisiarum : size-specific responses to local group composition
TLDR
In gastropods the presence of relatively permanent small local mating populations is the critical factor associated with social control of sex change, rather than mode of larval development and dispersal. Expand
Social Behavior, Group Structure, and the Control of Sex Reversal in Hermaphroditic Fish
TLDR
The social and developmental hypotheses for the control of sex reversal are examined and a new hypothesis is proposed: females are stimulated to change sex by the changes in a specific behavioral measure of a critical magnitude. Expand
