three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in finike bay for red mullet (mullus barbatus l., 1758). the sampling program was arranged during february to may 2012. holt (1963) method was used for selectivity of trammel nets. red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...
Performance in one stage of a complex life cycle may affect performance in the subsequent stage. Animals that start a new stage at a smaller size than conspecifics may either always remain smaller or they may be able to "catch up" through plasticity, usually elevated growth rates. We study how size at and date of metamorphosis affected subsequent performance in the terrestrial juvenile stage an...

Females grew faster than males and reached a greater size. Mean body sizes of first year cohorts, size plots of known age snakes, and mean body sizes of the largest snakes were in agreement with size-age ...

Thresholds to sexual maturity—either age or size—are critical life history parameters. Usually investigated in short-lived organisms, these thresholds and interactions among age, size, and growth are poorly known for long-lived species. A 34-year study of captive green turtles (Chelonia mydas) that followed individuals from hatching to beyond maturity provided an opportunity to evaluate these p...
