Fig. 4From: Trophic interactions as determinants of the arbuscular mycorrhizal fungal community with cascading plant-promoting consequencesAMF abundance inside the body of the two dominant fungivorous nematodes Aphelenchoides (a, b) and Aphelenchus (c, d). a and c, × 200 magnification. AMF abundance inside Aphelenchoides and Aphelenchus was expressed as copy numbers of the AMF 18S rRNA gene per nematode, respectively. Bars (n = 3) with different lowercase letters indicate significant differences as revealed by Tukey’s HSD tests (P < 0.05). M0, no manure; M1, low manure; M2, high manure; M3, high manure plus limeBack to article page
