For diet, we typically use trnL primers for plants, ITS primers for fungi, COI primers for insects, and 12S primers for vertebrates.

For parasites, we typically use 18S primers.

For pollen, we use the same trnL primers as for plants in diet.

For microbiomes, we use 16S primers for bacteria and ITS primers for fungi.

Upon consultation, we can use other primers to help quantify other taxonomic groups.
