Figure 3 in Intragonadal evaluation of sexual steroid hormones during three reproductive events in two species of Peromyscus (Rodentia: Cricetidae)
Figure 3. Fluctuations of each intraovarian [SSH] in the ∆4 pathway throughout three reproductive events in two species of Peromyscus. Mean concentrations of sexual steroid hormones, [SSH], were obtained from estrous cycle, pregnancy and lactation in free-living, adult females of P. melanotis (A) and P. difficilis (B). Symbology as in Fig. 2. Note that scales differ; complete ANOVA information is available in Table S2.
Figure 1 in Intragonadal evaluation of sexual steroid hormones during three reproductive events in two species of Peromyscus (Rodentia: Cricetidae)
Figure 1. Intraovarian contents of selected ∆ 4 pathway's SSH in two Peromyscus species. Sexual steroid hormones (SSH: progesterone, P4; androstenedione, A; testosterone, T; estradiol, E2) were obtained from free-living, adult females of P. melanotis (A) and P. difficilis (B), during a complete estrous cycle (CEC: proestrus to diestrus), and after ovulation (vertical arrows) followed by fecundation in a successful estrous cycle (SEC: proestrus, estrus + early gestation 1 and late gestation 2 + overall lactation); note that proestrus and estrus data from CEC are duplicated in SEC). The oogenetic and anabolic/ catabolic phases of the ovarian cycle are also depicted (see Table 1).
Fig. 3 in Trends in ovarian development, plasma vitellogenin, and steroid hormones in female Malaclemys terrapin (Schoepff, 1793) from coastal Louisiana
Fig. 3. Concentrations of vitellogenin (A), testosterone (B), and estradiol (C) throughout sampling periods of female Diamondback Terrapins captured in Louisiana. Dashed lines within each box indicate the mean of the data, bold lines within each box indicate the median of the data, the upper and lower edges of the boxes represent the 75% and 25% quartiles, and bars represent the minimum and maximum values. Solid black circles represent outliers, and different letters indicate significant differences (P<0.05) between sampling periods. The mean and median overlap in some categories, so both lines may not be visible.
Fig. 2 in Trends in ovarian development, plasma vitellogenin, and steroid hormones in female Malaclemys terrapin (Schoepff, 1793) from coastal Louisiana
Fig. 2. Ovarian follicle diameter throughout sampling periods of female Diamondback Terrapins captured in Louisiana. Dashed lines within each box indicate the mean of the data, bold lines within each box indicate the median of the data, and the upper and lower edges of the boxes represent the 75% and 25% quartiles. T bars represent the minimum and maximum values. Solid black circles represent outliers. Note n = 4 for late nesting period, but only two samples were used in the analysis as the others lacked any detectable follicles. The mean and median overlap in some categories, so both lines may not be visible.

Data from: Feather steroid hormone concentrations in relation to age, sex, and moulting time in a long distance migratory passerine
In birds, concentrations of testosterone (T) and corticosterone (Cort) are closely connected with many morphological, behavioural and other physiological traits, including reproduction, metabolism, immunity, and fitness. The direction of the effect of these hormones on above-mentioned traits, and the potential feedback between hormones are in general unclear; in addition, knowledge on how age and sex can affect T and Cort concentrations is still inconsistent. Our study used a novel method to analyse testosterone and corticosterone in feathers (Tf, Cortf) based on the pre-column chemical derivatization of hormones before LC-MS/MS analysis. Unlike previously used methods (RIA, EIA), our analytical procedure allows simultaneous analysis of both hormones from small amounts of feathers (4-25 mg) and thus overcomes the problem of insufficient detection limits. We applied this method to reveal associations between Tf and Cortf hormone concentrations and feather growth, age, and sex in feathers grown during the post-breeding (flanks) and pre-breeding (tails) periods in barn swallows (Hirundo rustica). There was neither a correlation between pre-breeding and post-breeding Tf, nor between pre-breeding and post-breeding Cortf. Tail Cortf concentrations were negatively associated with tail feather growth rates. Feather hormone concentrations were correlated in the pre-breeding period, negatively in males but positively in females. Both Cortf and Tf were higher in young birds compared to older ones, indicating either an age-related decrease in hormone concentrations within individuals, or the selective disappearance of individuals with high steroid concentrations. Males and females did not differ in Cortf, but Tf concentrations were higher in males than females, particularly during the pre-breeding period. In this study, we provide an effective method for analysing hormones in feathers in an ecological context, especially in situations when the total amount of feathers available for the analysis is limited.
