this study describes length-weight relationships of five species (platycephalus indicus, pseudorhombus elevates, plicofollis tenuispinis, grammoplites suppositus, pomadays stridens) collected from persian gulf (khuzestan province, iran) during december 2009 to november 2011. a total of 2065 specimen were examined for this study. the relationship between weight and total length were estimated: w...

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...

A long-standing question in developmental biology is how do growing and developing animals achieve form and then maintain it. We have revealed a critical transition in growth control during zebrafish caudal fin development, wherein a switch from allometric to isometric growth occurs. This morphological transition led us to hypothesize additional physiological changes in growth control pathways....

Abstract Scomberoides commersonnianus is one of the commercially important fishes of the family Carangidae. In this study, 563 specimens (292 males, 247 females, and 24 sexually unknown ones) were collected from the north-west of the Persian Gulf. Length-weight relationships and condition factors were determined for each sex in four length classes within different seasons. In general, the growt...

We begin a systematic study of Euclidean Piecewise Isometric Dynamical Systems (p.i.d.s.) with a particular focus on the interplay between geometry, and symbolic dynamics , and the group of isometries associated with p.i.d.s. We investigate various aspects of the dynamical information contained in the coding: symbolic growth and the periodic behavior of codings and cells. This theoretical inves...

The length-weight relationships, condition factor and morphometrics of 10 species of the genus Alburnoides are provided from Iranian inland water. The a values ranged from 0.0037 (Alburnoides damghani) to 0.0128 (Alburnoides namaki), the b values ranged from 2.87 (A. namaki) to 3.50 (A. damghani) and the coefficient of variation (r2) ranged from 0.90 (Alburnoides samii) to 0.99 (A. namaki). Of ...
