Assessing the diversity and spatial distribution of nematodes in the Store Mosse National Park (Sweden) using metabarcoding

Nematode taxa of the Store Mosse National Park in the south of Sweden were surveyed using DNA metabarcoding. Samples were collected from a range of media across all five vegetation types the park spans. A total of 50 samples consisting of soil, litter, lichens, sphagnum, roots, wood, moss, fungus and anthill materials were analysed. Nematodes were characterised using a ~350 bp region of their 18S ribosomal RNA gene. The analysis identified 47 families, 76 genera (25 new to Swedish fauna) and 60 species (32 new to Swedish fauna).
