These data were combined with the species abundance in 54 caves and adits in order to estimate their organic carbon bulk and carbon input into these habitats. In Central European caves, Troglophilus cavicola, T. neglectus, Faustina illyrica, Amilenus aurantiacus and Scoliopteryx libatrix are the most important vectors of carbon between the epigean and hypogean habitats. In contrast to the general assumption, carbon total contribution to caves via dead bodies is only 0.15% of total migratory biomass, and it is not directly available to troglobionts because of infection with entomopathogenic fungi. In winter, together with predated migratory specimens, carbon input does not exceed 0.3% of the total migratory biomass. This situation should be carefully examined in every karstic region inhabited by distinctive faunaV enajstih najpomembnejših vrstah kopenskih nevretenčarjev v jamah Slovenije smo proučili razlike v biomasi, suhi masi, energijski vsebnosti in količini ogljika v zimskem obdobju. Te podatke smo obravnavali v kombinaciji z abundanco v 54 jamah in rudnikih, da bi ocenili količino organskega ogljika v njih ter vnos ogljika v te habitate. V srednji Evropi so najpomembnejše vrste, ki vnašajo ogljik v podzemlje, Troglophilus cavicola, T. neglectus, Faustina illyrica, Amilenus aurantiacus in Scoliopteryx libatrix. V nasprotju s splošno domnevo, prispevajo poginuli osebki le 0,15 % C glede na skupno migrirajočo biomaso, ki ga troglobionti ne morejo neposredno uporabiti zaradi okužb z entomopatogenimi glivami. Skupaj z uplenjenimi osebki vnos ne presega 0,3 % biomase teh vrst. Te razmere je treba skrbno proučiti v vsakem kraškem predelu, kjer se migrirajoča favna razlikuje od ostalih območijTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZRC SAZU
