General and Comparative Endocrinology

Morphological and hormone data from migrant and resident female dark-eyed juncos caught during seasonal sympatry in early spring (12 March- 4 April) near Mountain Lake Biological Station in Pembroke, VA.

Data from female and male Northern Jacanas (Jacana spinosa). Spreadsheet includes individual levels of testosterone in circulation, aggressive responses to simulated territorial intrusion, and morphological traits used in mating competition.

Data for "Post-natal corticosterone exposure downregulates the HPA axis through adulthood in a common passerine".

All data analyzed in the present study.

Gerbil field testosterone measurement, and the results of GnRH challenge and implant experiment, along brain AR mRNA expression results.

Data for Paitz et al. 2019 submission to GCE

Normalized data from quantitative PCR for genes of interest related to reproduction (AR, AROM, ER, GnRH,GR, LHR, and MR) in migratory and sedentary female dark-eyed juncos (small songbird). The dataset includes individual ID for each subject, subspecies of the female (resident = sedentary), and the date each individual was captured.

Morphological and plasma reproductive hormone measures in male houses that were food-restricted for 6 weeks. Finches were administered GnRH and NMDA, and the plasma LH response was measured to assess GnRH regulation.

Gibbons of the genus Nomascus exhibit strong sexual dichromatism in fur color. Change of fur color in sub-adult wild Nomascus females is associated with the onset of puberty and the time of their dispersing. The fact about the more observed reproductive suppression in monogamous species is known, particularly in females. The variability in color change may be therefore influenced by social factors. In this study, we determined whether captive Nomascus females establish reproductive maturity prior to dispersing with an association to their fur color. We collected 287 fecal extracts to analyze pregnandiol -3- glucuronide and 17β estradiol profiles of 4 sub-adult females (Nomascus leucogenys and Nomascus gabriellae) and 183 samples from their mothers, using enzyme immunoassays. The sub-adult females were monitored aging from 4 years old. Their hormone profiles showed the onset of ovulatory cycling between ages of 4.6-5.8 years. Based on the information about the estrogen influence to the secondary sex characteristic (color of female) the positive link between estrogen concentration and age of the sub-adult females was found. However, the amount of the estrogen can apparently determinate the presence of the mother. If the mother was presented, the level of estrogen was higher than if the mother was missing. Our findings suggest that the probability to the beige color of the sub-adult females increased with increased age and if they were without mother. Due to a small number of females in this study, we can only assume a certain degree of maternal influence to the fur color change of their daughters.
