Statistical analysis showed interactive effects of time and symbiont type; post hoc (Tukey LSD) results are shown only where significant. Seasonal differences within a single symbiont are indicated as: *, 0.01 < P < 0.05; **, 0.001 < P < 0.01; ***, P < 0.001 in relation to time points March 2005, November 2005, March 2006, and November 2006. Significant differences between symbiont types at the same time of year are shown with #, 0.01 < P < 0.05; ##, 0.001 < P < 0.01; ###, P < 0.001 followed by the respective significantly different symbiont type.
