Erratum: Allometric analysis of a morphological anti-predator trait in geographic populations of Japanese crucian carp

چکیده
“The mean relative body depth of the triploid asexual Japanese crucian carp differed significantly among 13 populations (Fig. 3, Welch’s one-way ANOVA weighted for unequal variances, F12,67.08 = 26048, P < 2.2 × 10−16). The total variation in the relative body depth was 45% explained by the between-population variation and 55% by within-population variation (Kulinskaya and Staudte’s weighted coefficient of determination, ρ2 = 0.45). Within-population variation in the relative body depth was significantly different among populations (Fig. 3, Levene’s test of homogeneity of variances: F12,420 = 12.48, P < 2.2 × 10)”.

Allometric analysis of a morphological anti-predator trait in geographic populations of Japanese crucian carp
Costly anti-predator traits tend to be expressed only in high-predation conditions. For the cyprinid fish genus Carassius, deeper body depth is more adaptive to avoid predation by gape-limited piscivorous fish, but it raises swimming costs. It is therefore predicted that the relative body depth will decrease when the prey fish has reached a size larger than the predator gape-size. This predicti...
متن کاملPredator-induced morphology enhances escape locomotion in crucian carp.
Fishes show a remarkable diversity of shapes which have been associated with their swimming abilities and anti-predator adaptations. The crucian carp (Carassius carassius) provides an extreme example of phenotypic plasticity in body shape which makes it a unique model organism for evaluating the relationship between body form and function in fishes. In crucian carp, a deep body is induced by th...
متن کاملMassive Production of All-female Diploids and Triploids in the Crucian Carp
In many species of aquaculture importance, all-female and sterile populations possess superior productivity due to faster growth and a relatively homogenous size of individuals. However, the production of all-female and sterile fish in a large scale for aquaculture is a challenge in practice, because treatments necessary for gynogenesis induction usually cause massive embryonic and larval morta...
متن کاملBody color development and genetic analysis of hybrid transparent crucian carp (Carassius auratus).
The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern a...
متن کاملSome biological parameters of Silver Crucian carp, Carassius auratus, in the international wetlands of Alma-Gol and Ala-Gol (Golestan Province, Iran)
In the present study, age, growth and reproduction of Carassius auratus were investigated in the Alma-Gol and Ala-Gol (northern Iran) from September 2000 to August 2002. Among the total of 1450 specimens, the estimated ages ranged from 0+ to 8+ years. C. auratus showed an allometric growth, negatively in Alma-Gol and positively in Ala-Gol. The von Bertalanffy growth curves were fitted to mean t...
