Title IBI duration
Downloaded 14 times
Description This dataset was used to conduct our first analysis, which examined the duration of IBIs and their component phases. For this analysis we used 36 years of data (collected between 1977 and 2012) on reproductive states, demographic events, dominance rank, and rainfall for 160 wild-feeding females. Specifically, we had a total of 490 IBIs for 160 females that fit our analysis criteria (see Methods - Data Analysis), with each female contributing an average of 3 IBIs to the dataset (range: 1-10). Note that female identity and pregnancy identity have been anonymized and the ID given were identical across tables.

Title Fat Score
Downloaded 4 times
Description This dataset included the body fat scores, which were used to conduct our second analysis. For this analysis, we had 345 body fat scores for 105 females during 260 IBIs (collected between 2008 and 2014). Scores were collected during July, August, or November of each year, and the timing of the score within the IBI varied across females. 183 fat scores were assessed during PPA, 70 during cycling, and 92 during pregnancy. For any given phase of a given IBI, females were usually assessed once, but in a few cases females were assessed twice during a given PPA (n=11). For these 11 cases an average body fat score was calculated so that each female contributed only one score for each PPA.

Title Fecal hormones
Downloaded 2 times
Description This dataset includes the data for our third analysis, which examined fecal glucocorticoids (fGC), fecal estrogens (fE), and fecal progestogens (fP) during PPA as a function of the number of months to sexual cycle resumption, or during the various phases of the sexual cycles (early or late follicular and luteal) as a function of the number of cycles to conception. For fGC and fE we had a total of 5,470 hormone samples collected between 2000 and 2014 for 138 females during 549 IBIs. Of these samples, 4,150 fecal samples were collected during PPA, and 1,320 were collected during cycling. Each female contributed fecal samples from an average of 4 IBIs (range: 1-11) with an average of 10 hormone samples per IBI (range: 1-55) and an average total number of 40 samples per female (range: 1-145). For fP, we had a smaller sample size of 4,095 hormone samples collected between 2003 and 2014 for 130 females during 456 IBIs; 2,922 were collected during PPA and 1,173 during cycling. Each female contributed samples from an average of 3.5 IBIs (range 1-8), with an average of 9 (range 1-47) samples per IBI, for an average total number of 32 (range 1-141) samples per female.
