Detection frequencies of consumer- and prey-DNA. Detection frequencies of lycosid and prey DNA in DNA extracts of full-body and faecal samples of lycosid spiders collected in three glacier forelands using three diagnostic multiplex PCR assays. Targeted DNA: Pardosa spp. at genus level (Pard), P. nigra (P.nig), P. saturatior (P.sat), Collembola (Coll), glacier harvestman Mitopus glacialis (M.gla), carabid beetles [Nebria germari (N.ger), N. jockischii (N.joc), Oreonebria castanea (O.cas)], and linyphiid spiders [Agyneta nigripes (A.nig), Diplocephalus helleri (D.hel), Entelecara media (E.med), Erigone tirolensis (E.tir)]. DNA of the linyphiid Janetschekia monodon and of the carabid N. rufescens were not detected. Error bars represent 95% tilting confidence intervals from 9999 bootstrap resamples; non-overlapping confidence intervals are interpreted as significant differences.
