In terms of VB parameters and length at maturity, the population is also very similar to marine cod populations at northern latitudes (e.g. Northeast Arctic cod, northern cod; Kuparinen and Hutchings 2012).
6 7 Skeletal maturity of population samples can be compared with reference samples, most commonly the Tanner–Whitehouse III (TW3) charts, 2 to compare relative advancement or delay.
where represent the immature and mature populations densities, respectively, represents a constant time to maturity, and and are positive constants.
At maturity, different populations and subspecies of cutthroat trout can range from 6-40 inches in length, depending on habitat and food availability.
Observations by Sheffer et al. (1997) suggested that there may be differences in the timing of male sexual maturity among populations, a trait with potentially important fitness consequences.
Crickets may produce micropterous as well as macropterous individuals in response to variable availability of annual thermal energy [ 30], and young mice and voles may vary in age of maturity within populations in dynamic environments [ 31].
Relatively few common garden experiments have compared size and/or age at maturity among populations, even though this trait is strongly suspected to have evolved in many exploited fish stocks (Dieckmann and Heino 2007; Jørgensen et al. 2007; Heino and Dieckmann 2008).
Domestication, the propagation of selected individuals, leads to uniform population maturity, loss of natural seed dispersal, and an increase in the yield of harvestable seed.
(tau_{i}) represents a constant time to maturity of prey population in patch i ((i=1,2)), that is, immature prey individuals and mature individuals are divided by age (tau_{i}) in patch i ((i=1,2)).
There are two factors important for timing of puberty, the maturity of gonadotroph population manifested by the adequate size of LH-containing cell subpopulation and the circumstances of an external environment optimal for reproductive functions in adults.
