Identification of recaptured individuals
The R package RClone (Bailleul et al., 2016) was used to identify duplicate genotypes in the dataset and to detect recaptured individuals. Using the allelic frequencies of the dataset, RClone simulates a reproduction event and compares the genetic distances between genotypes in the simulated and the observed populations. This allows for a threshold to be determined, below which genotypes in the observed population may be too similar to occur as a result of reproduction. Thus, the genotypes of all individual pairs that had less than 5 differences at any locus were double-checked with GENEMAPPER, and the data were crosschecked with field information to identify recaptured individuals.
