Resource economy of carnivorous plants: Interactions between prey capture and plant performance in three subarctic Pinguicula species
In this thesis, I have studied in situ the resource economy of the three carnivorous plant species Pinguicula alpina, P. villosa and P. vulgaris in a subarctic environment. The prey capture varied among individual plants, years and species. It was higher in young leaves then in old ones. P. vulgaris...
