^aFirst, an average brood number per individual was calculated per pool, then the average of the pools was reported.

^bN, number of pools tested; n, total numbers of individuals tested.

^cAverage brood size per worm in pools is the sum of all the daily brood sizes.

^dRS is the number of days with average daily individual brood counts >0 based on one-sample t-test.

RS, reproductive span.
