Supplemental Information

Figure S1. Pictures of sorted specimens

Pictures of the specimens sorted into small, medium and large individuals. Also provides information on how S, M and L tissue was pooled to generate the proportionally sorted (So) and unsorted (Un) samples.

DOI: 10.7287/peerj.preprints.2561v3/supp-1

Figure S2. Flowchart detailing laboratory processing

Overview of the steps carried out for sample sorting and processing in the laboratory.

DOI: 10.7287/peerj.preprints.2561v3/supp-2

Figure S3. DNA extraction protocol

Shows the step where the digested buffers of S, M and L were pooled to generate unsorted (Un) and sorted (So) samples.

DOI: 10.7287/peerj.preprints.2561v3/supp-3

Figure S4. Sequencing depth and sequences discarded in bioinformatic processing

Barplot showing the number of total reads and proportion of sequences discarded in subsequent bioinformatic processing steps for all samples.
