Description	Oxygen concentration and electrical redox potential were measured using a small Clark-type oxygen sensor and a miniature platinum electrode respectively in the fluid of excised and intact traps of six aquatic Utricularia species and in Genlisea hispidula traps. [O2] in the traps of both genera always approached zero (median 0.0-4.7 μM). The [O2] decreased after electrodes were inserted into Utricularia traps at a rate from 0.09 to 1.23 mM h-1. Effectively anoxia is demonstrated in Utricularia and Genlisea traps. This is probably below the critical [O2] for prey survival, and causes captured prey to die of suffocation.

(en) Koncentrace O2 a elektrické redox potenciály byly měřeny Clarkovým mikročidlem a Pt mikroelektrodou v tekutině odříznutých a intaktních pastí u 6 vodních druhů Utricularia a v pastech Genlisea hispidula. [O2] v pastech obou rodů se vždy blížila nule (medián 0,0-4,7 μM). [O2] v tekutině pastí bublinatek klesala po jejich napíchnutí rychlostí 0.09-1.23 mM h-1. Prakticky anoxie je demonstrována v pastech Utricularia a Genlisea. To je zřejmě pod kritickou hladinou [O2] pro přežívání kořisti a způsobuje úhyn chycené kořisti zadušením. (cs)
