Fecundity data

Spreadsheet "Fecundity" contains the results of the fecundity assay. The aphids used in this experiment either contained no known secondary symbionts or were artificially infected with different complements of symbiont species. We counted the number of offspring produced by single wingless aphids, representing one of five genotypes and hosting one of seven symbiont complements, during three (grain aphids) or four (pea aphids) consecutive three-day intervals. In the spreadsheet, rows contain offspring counts for individual aphids. Columns are as follows: >>>Species - Aphid species, two levels (A. pisum, S. avenae). >>>Gen - Aphid genotype, five levels (145, J68, J102, Co23, Co26). >>>Sym - Symbiont infection status. Ha / Ri / Sp represent Hamiltonella defensa, Rickettsia sp. or Spiroplasma sp., and the value after underscore represents the genotype of original pea aphid host. >>>Block - The ID number of experimental block. In all cases, lines of a given genotype were tested at the same time (and so have the same block ID number), separately from lines of other genotypes. The fecundity assay for genotype 145 was conducted in two blocks. >>>D10 - number of offspring produced by single wingless aphids before its 10th day of life. >>>D13, D16, D19 - numbers of offspring produced by single aphids during consecutive three-day intervals. >>>Fec_total - total number of offspring produced during 16 days (S. avenae) or 19 days (A. pisum). Missing data are indicated by “NA”
