“…Relative body size was then employed as an estimate of relative age and skeletal maturity. Estimates of relative ages based on total body length may be unreliable for Alligator, however, due to potential variation in size and/or growth rates between sexes and among habitats and geographical regions (McIllheny, 1935;Peabody, 1961;Bellairs, 1970;Andrews, 1982;Jacobsen and Kushlan, 1989;Magnussen et al, 1989;Castanet et al, 1993;Dalrymple, 1996;Wilkinson and Rhodes, 1997). Sex and geographical region were known for the majority of the study sample; variation due to other factors could not be controlled for in the collections examined.…”

“…These may include sexual dimorphism; seasonally interrupted growth; environmental conditions of habitat, diet, and temperature; and indeterminate growth (McIllheny, 1935;Peabody, 1961;Bellairs, 1970;Andrews, 1982;Jacobsen and Kushlan, 1989;Magnussen et al, 1989;Castanet et al, 1993;Dalrymple, 1996;Wilkinson and Rhodes, 1997;Elsey et al, 2000;. To the extent possible, effort was made to control for these variables within sizebased analyses of the study sample.…”

“…At the beginning of the experiment the alligators ranged in age from 3.3-8.4 years (mean = 5.7 ± 1.2 SD) and 78.6-114.8 cm total length (mean = 93.4 ± 13.4 SD). All individuals were immature males (size at maturity = 1.5-1.8 m; Abercrombie 1989;Dalrymple 1996), which minimized the possible confounding effect of variation in metabolism between sexes and life stages. Also, because juvenile alligators grow at similar rates until maturity (i.e., growth rates vary little across ages and sizes of juvenile alligators; Jacobsen and Kushlan 1989) it is unlikely that variation in growth rates would confound results.…”

“…The study was conducted from Slough, the main source of freshwater flow through ENP (Dalrymple 1996). The SRE is a mangrove dominated tidal river with tidal mean amplitude of 0.5-1.0m (Romigh et al 2006) and depths that range from 0.5-4.0m.…”
