Ecological study of the aquatic carnivorous plant Utricularia australis R.Br. (Lentibulariaceae)
Utricularia australis is an aquatic rootless carnivorous plant that takes up nutrients through shoots or from trapped prey digested in its bladders. As the information on the ecology of this species is scarce, the main environmental factors which favour or limit its growth were analysed. Habitat cha...

is an aquatic rootless carnivorous plant that takes up nutrients through shoots or from trapped prey digested in its bladders. As the information on the ecology of this species is scarce, the main environmental factors which favour or limit its growth were analysed. Habitat characterization was carried out on 23 aquatic sites in Central Italy where
U. australis
occurred. Diverse water chemical and physical factors and aquatic plant dominants were sampled and compared to
Utricularia
coverage. Species response curves with respect to each analysed ecological factor were elaborated. Despite the large environmental variation among sites,
U. australis
did show some ecological preferences. Optimal growth of
Utricularia
was associated with sunny sites (~ 1500 µmol photon m
