Feeding of biofilm-dwelling nematodes examined using HPLC-analysis of gut pigment contents

  title={Feeding of biofilm-dwelling nematodes examined using HPLC-analysis of gut pigment contents},
  author={Nabil Majdi and Mich{\`e}le Tackx and Walter Traunspurger and Evelyne Buffan-Dubau},
The natural feeding behaviour of the nematodes Chromadorina bioculata (Schultze in Carus 1857) and Chromadorina viridis (Linstow 1876) was studied in situ, within epilithic biofilms of the Garonne River (France). Based on their feeding-type characteristics and population dynamics, it was hypothesised that these species feed selectively on microphytobenthos (MPB) within the biofilm, and that among MPB groups, diatoms are preferred. High-performance liquid chromatography (HPLC) was used for… CONTINUE READING
