“…Early sex change might be a viable alternative strategy if non-reproductives have decreased mortality rates or increased growth rates [7], so that a small decrease in current reproductive success results in a much larger gain in RV. Early sex change in the spotlight parrotfish Sparisoma viride appears to be Review favoured because non-reproductive males grow faster than do territorial males [40] and do not appear to suffer markedly higher mortality rates [41]. Simple multiplications of size-based fecundity and number of spawns per year indicate that the lifetime fecundity of early sex changers is similar to that of individuals that change sex later in life [41]; thus, early sex change can be a viable alternative breeding tactic in this species.…”

Here, we review recent empirical advances that have improved our understanding of why and when sex change occurs. We show that sex-changing animals use a greater diversity of strategies to increase their reproductive success than was previously recognized: some individuals change sex early, others change sex late, some individuals change sex more than once, and others do not change sex at all. These different strategies can be unified by the principle that individuals change sex when it increases their reproductive value. The breeding tactics (male, female or non-breeder) adopted by individuals often appear to be adaptive responses to their own social-ecological context and variation in these conditions results in significant differences in the timing of sex change within and between species.

“…Some phenotypic plasticity is clearly adaptive (Dodson 1989, Scharloo 1989, Newman 1992; however this is difficult to demonstrate empirically (Newman 1992, Dudley & Schmitt 1996. Common in terrestrial taxa, phenotypic plasticity has also been documented in a broad range of marine biota including fishes (Robinson & Wilson 1995, Turigan et al 1995, Vanrooij et al 1995, molluscs (Etter 1996, Trussell 1996, crustaceans (Lively 1986, Hazlett 1995, Mokady et al 1999, echinoderms (Ebert 1996), sponges (Palumbi 1984), bryozoans (Harvell 1992, Okamura 1992 and corals (Foster 1979, Bruno & Edmunds 1997, Muko et al 2000.…”

Environment-dependent variation in the morphological, physiological, or behavioural expression of a genotype is termed phenotypic plasticity. To test for small-scale morphological plasticity in the Indo-Pacific massive corals Favia speciosa (Dana, 1846) and Diploastrea heliopora (Lamark, 1816), fragments (clone-mates) from 12 colonies of each species were reciprocally transplanted among 6 new habitats located within 2 environmental gradients: a depth cline and a nearshore-to-offshore gradient in sedimentation rates and total suspended solids (TSS). After 7 mo, all fragments were collected, cleared of tissue, and 10 morphometric characters extracted from randomly chosen corallites. Reaction norms, analysis of variance, and canonical discriminant analysis describe environmentinduced changes in corallite architecture. These changes are more pronounced in the depth cline than along the sediment gradient. Similarity of response is suggested by exploratory factor analysis where, for both species, size attributes dominate the first factor, antisymmetry the second, and corallite exsertion the third. Highly significant genotype × environment interactions for F. speciosa indicate that, for this species, genotypes vary in the level of plasticity expressed. Light and TSS emerge as the primary correlates influencing morphological change, although other parameters might act additively, synergystically or antagonistically with them. In shallow waters, increased corallite exsertion may enhance light capture or, alternatively, protect the central (oral disc) area of each polyp from harmful UV radiation. Morphological variability, combined with environment-induced changes in pigmentation, could impede accurate identification of these taxa.

“…There is a wealth of information on the biology of Sparisoma viride, provided through the research programs of reef fish biologists who studied this species in Bonaire (van Rooij et al 1995a,b, 1996a,b, Bruggemann et al 1996, van Rooij & Videler 1997. These studies have provided a comprehensive picture of the ecology and reproductive biology of this species in Bonaire.…”

“…These studies have provided a comprehensive picture of the ecology and reproductive biology of this species in Bonaire. An important component of these studies has been the analysis of growth (van Rooij et al 1995a) and mortality rates (van Rooij & Videler 1997). These studies were largely size-based and therefore provided limited information on age-specific properties of the study populations or estimates of maximum life spans.…”

The parrotfish Sparisoma viride is an abundant and ecologically important member of the tropical NW Atlantic reef fish fauna. Sagittal otoliths of 417 individuals were analysed to estimate age-based demographic variables at 4 localities (Lee Stocking Island, Barbados, Los Roques Archipelago and the San Blas Archipelago) spanning 14°of latitude. The sampling localities ranged from an area protected from trap-and net-based reef fisheries (Los Roques) to an area supporting a dense human population and sustained trapping and spearing for reef fishes including S. viride (Barbados). Examination of sectioned sagittal otoliths from each locality revealed regular increments in the sagittal matrix. A preliminary validation at San Blas was consistent with these increments being annual check marks. These increments provided estimates of age structure, maximum longevities and mortality rates for the 4 study populations of S. viride. Von Bertalanffy growth functions fitted to each size-at-age plot generated similar growth curves from 3 of these 4 localities. The exception was Lee Stocking, where fish grew faster and reached a substantially larger size than those from the other 3 localities. Further analysis of the growth curves demonstrated that the differences between Lee Stocking and the other localities were attributable to more rapid growth over the first 4 yr of life. Agebased growth curves derived from the Los Roques population were very similar to a size-based curve generated by an independent study on S. viride carried out in Bonaire, adjacent to Los Roques. Maximum longevities for all 4 of our populations varied from 7 to 9 yr. Mortality rates generated from catch curve analysis were also similar among localities and suggest that maximum life spans do not exceed 12 yr. This result differs from that obtained at Bonaire, where repeated censuses of tagged fish suggest 30 yr maximum longevity. Abundances of S. viride varied 3-fold among localities, being highest at Los Roques (protected from reef fishing), lowest at Barbados (high fishing) and Lee Stocking (low fishing). Thus our age-based study suggests that S. viride is a relatively short-lived fish with consistent demographic parameters over a range of localities, latitudes and fishing intensities.
