1. Samples and Date
Gentoo penguin scats were collected from Cumberland Bay, South Georgia (from the Maiviken colony). Visits were made weekly between 3 April and 19 Sep 2018 (one visit in June was missed owing to avalanche risk). During each of the 24 visits, 25 fresh scats were collected, producing a total of 600 samples. Samples were scooped into a 2 ml plastic screw-top tube containing 80% ethanol with a clean spatula and frozen at -20 degrees.

DNA was extracted from ~30 mg of faecal material using the Promega Maxwell RSC Tissue DNA Kit.
Each extraction contained a soft part or ~500ml of EtOH slurry. The samples were spun down, the EtOH was poured off, the sample was re-suspended in 120ul of S.T.A.R buffer and homogenised. 100ul of the supernatant was added to well number 1 and samples were eluted in 100ul of TE.
2. Plate Layout
Samples were diluted 1/10 and plated out on 96 well plates. Each plate had a positive control (fish, squid, shrimp DNA mix) and a negative PCR control.
3. 1st Round PCR.
All samples were analysed using a highly conserved metazoan primer set that amplifies a region of the nuclear 18S gene ( McInnes et al. 2017a). The first round PCR is to amplify the target marker and add sample-specific (7bp) multiplex-identifier (MID) tags (forward and reverse primer) and Illumina sequencing primers. See sheet for PCR conditions.
4. 2nd Round PCR
The second round PCR is to add sequencing adapters and additional 8 bp MIDs. See sheet for PCR conditions.
