Abstract We examined the social organization and reproductive pattern of a population of Sparisoma cretense L. at Lampedusa Island (Italy). During the breeding season (July to September) individuals occur either in territorial or in non-territorial groups, which quantitatively differ with respect to use of space, sex-ratio and sexual activity. Territorial groups consist of one male plus one to three females, whereas in non-territorial groups as many as 54 fish share a common area. Among non… 

Spatial patterns in reproductive traits of the temperate parrotfish Sparisoma cretense

Effects of social organization on the feeding of the striped parrotfish, Scarus iseri

Parrotfishes contribute to important reef processes through their feeding and sociobiology may influence their relative ecosystem impact, with territorial and terminal individuals in both social groups more involved in the detrital food web and stationary groups contributing to a greater extent on algal removal.

Sexual development and reproductive demography of the green humphead parrotfish (Bolbometopon muricatum) in the Solomon Islands

An investigation of the reproductive biology of the green humphead parrotfish (Bolbometopon muricatum) from three areas in the Western Province of the Solomon Islands revealed that B. muricatum

Mating system in a small pelagic spawner: field case study of the mandarinfish, Synchiropus splendidus

Mating systems in fishes are extremely diverse, ranging from monogamy to multiple polygamous forms, some of which include alternative male mating tactics within species. The major reproductive mode

Frequency of Functional Sex Change in Two Populations of Dascyllus Melanurus Conforms to a Prediction from Sex Allocation Theory

The size distributions of fish with mixed-stage gonads differed between the two populations in a manner that was predicted from the theories of sex allocation and mating systems, which indicated that functional sex change was present and was more frequent than in the former population.

The Mediterranean parrotfish Sparisoma cretense is reported for the first time along the south-eastern coasts of Apulia (Ionian Sea, south-east Italy) and the possibility that climatic changes occurring in the Mediterranean basin (i.e. water warming) would be involved in the spreading of the species outside its typical distribution range is discussed.

Spawning aggregation behavior and reproductive ecology of the giant bumphead parrotfish, Bolbometopon muricatum, in a remote marine reserve

The mating system and spawning aggregation behavior of Bolbometopon from the protected, relatively pristine population at Wake Atoll provides crucial baselines of population density, sex ratio composition, and productivity of a spawning aggregation site from an oceanic atoll.

Sex allocation in the sex-changing marine goby, Coryphopterus personatus, on atoll-fringing reefs

The social and ecological factors that govern the amount of selection for sex change and the production of alternative male strategies in a protogynous goby, Coryphopterus personatus, on atoll-fringing reefs in Belize are investigated.

Two-way sex change in the endangered limpet Patella ferruginea (Mollusca, Gastropoda)

The occurrence of two-way sex change, or reverse sequential hermaphroditism, in P. ferruginea is confirmed and provides new direction for studies designed to address the mechanisms and factors that determine sex change and its effects on population dynamics.

Temporal Fluctuations and Settlement Patterns of Native and Lessepsian Herbivorous Fishes on the Lebanese Coast (Eastern Mediterranean)

S. rivulatus was the most tolerant and adaptable species, able to settle on a large range of substrates and habitats, including rock pools, muddy harbours and sea grass beds, and has probably replaced S. salpa on the coast of Lebanon, being more competitive than the native sparid.



On the sociobiology of four puerto rican parrotfishes (Scaridae)

Behavioral observations were made during SCUBA excursions out of the PRINUL underwater laboratory, off the west coast of Puerto Rico. Most of the work involved four species of parrotfishes, Sparisoma

Sexual development and sexuality in the Nassau grouper

Histological and demographic data indicate that the sexual pattern of the Nassau grouper is not monandric, and that, unlike other group species, the juveniles pass through a bisexual stage of gonadal development.

Movements, Foraging Groups, and Diurnal Migratons of the Striped Parrotfish Scarus Croicensis Bloch (Scaridae)

The numbers of male striped parrotfish may regulate the phenomenon of sex reversal in the scarids, and transfer experiments showed that stripedParrotfish have strong ties to a home reef.

Sexual patterns in the labroid fishes of the Western Caribbean, II, the parrotfishes (Scaridae)

The results of a two year investigation into the interactions of sex change, coloration, and mating behavior in nine Caribbean wrasses show that sex change from female to male appears to precede a change of coloration into the bright terminal phase.

Sex differentiation and gonadal development in the diandric, protogynous wrasse, Thalassoma bifasciatum (Pisces, Labridae)

One hypothesis that would unify many of the apparently diverse patterns of gonadal differentiation in teleost fishes under a single conceptual scheme is that individuals develop in a female direction

The taxonomic status of the controversial genera and species of parrotfishes with a descriptive list (family Scardiae)

This, the second major paper on scarid fishes by the author, discusses several difficult-to-identify species and brings together under one taxon certain males and females, previously thought to represent two or more species.

Criteria for the Diagnosis of Hermaphroditism in Fishes

The strongest indicators of protandry are transitional individuals whose gonads contain degenerating testicular tissue and developing ovarian tissue, and experimental production of transitional or sex-reversed individuals through manipulation of the social system may identify both protogyny and prot andry.

Cellular and dynamic aspects of oocyte growth in teleosts

Teleosts offer examples of virtually every conceivable type of ovarian physiology and provide a wealth of experimental material for exploring the cellular and hormonal mechanisms which regulate oocyte recruitment and growth throughout ovarian recrudescence.
