| Summary: | Different groups of ground-dwelling spiders share similar trophic niches in temperate forests - Data file Column codes clarification: ID, Sample name Order - Taxa order for sample Family - Taxa family for sample Region - southern taiga is indicated by ST and broadleaved forest as BL Fire - "fire" for areas, which were exposed to forest fire, "control" for non-treated Plot - Plot ID Body size, mm - size group of studied predator individuals Collembola Col3F-Col5R - detection of Collembola by GC PCR, binary Lumbricidae 185F-14233R - detection of Lumbricidae by GC PCR, binary Oribatida ORI S14 - ORI A16 - detection of Oribatida by GC PCR, binary Staphylinidae STA S6 - STA A3- detection of Staphylinidae by GC PCR, binary Diptera DIP S16 - DIP A17 - detection of Diptera by GC PCR, binary Gamasina GAM S7 - GAM A8 - detection of Gamasina by GC PCR, binary PCR-name - running sample ID used for PCRs d13C norm - standartized d13C values d15N norm - standartized d15N values SUMM PRED - the amount of predators detected by GC PCR SUMM HERB - the amount of NON-predators detected by GC PCR TOTAL POSITIVES - the total amount of groups detected by GC PCR LOG(Wet weight) - wet weight of studieв predator individuals, dec.log.(g) Hunting - hunting type of studied individuals, according to spider family Habitat (Lowest forest tier) Habitat (Highest forest tier) Habitat group - according to the lowest and highest habitat forest tier combination Collembola - expected feeding on Collembola, binary Diptera - expected feeding on Diptera, binary Lepidoptera - expected feeding on Lepidoptera, binary Coleoptera - expected feeding on Coleoptera, binary Hemiptera - expected feeding on Hemiptera, binary Esp.small - expected feeding on small prey (collembola and mites), binary Expect VS GutContent Collembola - expected to observed feeding on Collembola, binary Diptera - expected to observed feeding on Diptera, binary Coleoptera - expected to observed feeding on Coleoptera, binary Esp.small - expected to observed feeding on small prey (collembola and mites), binary SUM of positive hits - expected to observed feeding hits summ
