Fecal DNA metabarcoding-derived diets of deer in Sweden

The dataset comprises 2,568 diet samples from four deer species: 1,080 moose (Alces alces), 329 roe deer (Capreolus capreolus), 666 red deer (Cervus elaphus), and 493 fallow deer (Dama dama). These diets were analyzed using fecal DNA metabarcoding with the primer pair Sper01_F and Sper01_R, which amplify the P6-loop of the chloroplast trnL intron. Diet composition is represented by relative read abundances (RRA) across 210 molecular operational taxonomic units (MOTUs). Samples were collected from two landscapes in Sweden—BN (boreo-nemoral) and CB (coastal-boreal)—between 2015 and 2017.
