Interactions between a mycophagous Collembola, dry yeast and the external mycelium of an arbuscular mycorrhizal fungus
A plant growth system with root-free hyphal compartments was used to examine the interactions between a mycophagous Collembola (Folsomia candida Willem), dry yeast and an arbuscular mycorrhizal (AM) fungus [Glomus caledonium (Nicol. & Gerd.) Trappe and Gerdemann] in terms of Collembola reproduction, AM-hyphal length and AM-hyphal P transport.
Collembola reproduction was unaffected by AM mycelium, but a supplement of dry yeast increased the Collembola population size. The addition of dry yeast increased AM-hyphal P transport by increasing hyphal length. Collembola without yeast affected neither AM-hyphal growth nor AM-hyphal P transport, whereas Collembola with yeast decreased AM-hyphal P transport by 75% after 8 weeks.
The hyphal density of G. caledonium remained unaffected by Collembola except after 4 weeks in combination with yeast, when a 33% reduction was observed. The results of this experiment show that the interaction between F. candida and the external mycelium of G. caledonium is limited under the conditions imposed.
