Data for lifetime reproductive success in S. fulvus

Data description for “<b>Early predictors of female lifetime reproductive success in a solitary hibernator: an evidence for “silver spoon” effect”</b> Nina A. Vasilieva, Andrey V. Tchabovsky The table contains data for lifetime reproductive success of yellow ground squirrel females (<i>Spermophilus fulvus</i>), observed in the natural colony in Saratovskaya oblast’, Russia, in the vicinity of village Dyakovka (50°43′88″N, 46°46′04″E). COLUMNS DESCRIPTION: <b>Female ID</b> – female identity. <b>Litter ID</b> – the female’s natal litter identity. <i>Lifetime reproductive success predictors:</i> <b>Date of natal emergence</b> – date of the first emergence of the focal female from the natal burrow. <b>Weaning weight, g</b> – female body weight at the first emergence from the natal burrow. <b>N days between weightings</b> – number of days between the female weightings. <b>Weight gain rate, g/day</b> – early growth rate, the difference between consecutive weightings divided by the number of days between them (N_days≥15; the first weighing was the weaning weight). <b>Natal litter size</b> – size of the female natal litter at the first emergence from the natal burrow. <b>Mean distance to burrows of 20 nearest juveniles, m</b> – average distance from the female natal burrow to natal burrows of 20 nearest juveniles, including the littermates; used as a measurement of juvenile local density. <b>Distance to the village, m</b> - the shortest distance (m) from the female natal burrow to the nearest garden fence in the village adjacent to the colony; used as a correlate of the potential negative human effect and disturbance. <b>Adult population density, ind/ha</b> - the density of adult animals (<i>N</i> animals per 1 ha); used as a proxy for total population density within the colony in the year of female birth <b>Amount of rain in May-June</b>, mm - the total precipitation during May and June in the year of female birth. <b>Year</b> - the year of female birth. <i>Lifetime reproductive success components:</i> <b>Survival to adulthood (0-no, 1-yes) </b>– we considered the female survived to adulthood if it was registered in May after its first hibernation of later, i.e. it could potentially wean at least one litter. <b>Lifespan</b> - the number of full years between the female’s natal emergence and disappearance from the colony. <b>N weaned litters</b> – the lifetime number of weaned litters. <b>N weaned offspring</b> – the lifetime number of weaned offspring (weanlings). <b>N yearling offspring</b> – the lifetime number of offspring survived to maturation, i.e. the total number of offspring survived the first hibernation.
