  1. Scoring of Caenorhabditis populations in ten Orsay apples (O661-670) and ten Santeuil samples (S101-S110). These sets were chosen to represent a variety of Caenorhabditis population size and type, and maximize the proportion of positive samples (that is, the presence of Caenorhabditis is less frequent than would be suggested by these sets; see Additional Files 1 and 2 and Figure 5). Only a part of each apple was analyzed, which is taken into account for in the total census. Weight is in grams. Total census is on a Log scale. d: dauer larva. ad: adult. The tentative stage of the population is indicated: D, dauer stage; P, proliferating; P1, early stage of proliferation (no dauers); P2, intermediate stage (L3 and L4 stages present, as well as L2d or dauers); P3, late stage (many L1, L2d, dauers). The Caenorhabditis species was identified for a set of individuals of each population, as indicated in the last column. ~, approximately; Cbr: C. briggsae; Cel: C. elegans.
