Holothuria arguinensis, mammata and forskali are three common sea cucumber species found in the NE Atlantic, traded international markets susceptible to capture. Allometric relationships reveal if scaling between biometric characters proportional with growth, being a useful tool understand growth strategies. of were estimated compared them populations from different regions. These allometric re...

Total and regional allometric growth rates and termination sites of the spinal cord related to the respective vertebra were studied in 36 goat fetuses, from the Ahvaz slaughterhouse. These specimens were assigned to 3 groups, group 1 (CRL 10-20 cm), group 2 (CRL 21-30 cm), and group 3 (CRL 31-40 cm), each consisting of 6 male and 6 female fetuses. Observations in all 3 groups revealed that alth...

allometric growth pattern and body shape changes of the green terror (andinoacara rivulatus)(cichlidae) were studied using landmark-based geometric morphometric (gm) and traditional methods, from hatching up to 1266 hours post hatching (hph) under culture conditions. the left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

Metamorphic vertebrate species are of particular interest in ecological and evolutionary studies because the decoupling of larval and adult growth patterns potentially allows adaptive diversifications of the separate stages. Larval and adult growth might be much more constrained if allometric patterns were constant throughout ontogeny. To better understand how differential growth patterns might...

PURPOSE The purpose of this study was to examine the ontogeny and phylogeny of lens growth in a variety of species using allometry. METHODS Data on the accumulation of wet and/or dry lens weight as a function of bodyweight were obtained for 40 species and subjected to allometric analysis to examine ontogenic growth and compaction. Allometric analysis was also used to compare the maximum adult...

The relative growth of the fiddler crab Uca sindensis in Pohl Port was studied. Ten 0.5 m2 quadrates were randomly sampled monthly during low tide periods from October 2009 to September 2010. A total of 840 crabs, 449 (53.45%) males and 391(46.5%) ‌ females, were sampled. The Carapace width of males ranged from 5.5 to13.5 mm (mean ± SD) (8.92 ± 2.04), and of females from 5.0 to 11.5 mm (mean ± ...

in this study, 160 fishes were randomly collected from commercial catch by a cone net in babolsar port from january to october 2010. the biological features of specimens were measured. 2 + years old fishes made the dominant age group with 33.75% and 1 + and 5 + years old had the least frequency (8.75%). relationship between length and weight indicated negative allometric growth pattern (b=2.581...

1. West et al . (2001) describe a general model of ontogenetic growth in which growth represents the surplus of energy acquisition over maintenance energy requirement, which themselves are allometric (power) functions of body mass with exponents 3 / 4 and 1, respectively. Furthermore, the intercept of the maintenance requirement decreases with the – 1 / 4 power of adult mass. 2. These relations...
