“…Azul and Freitas (1999) also recorded seasonal variations in the numbers of mycorrhizal tips in a Q. suber forest, with the lowest numbers also recorded in autumn. In contrast, Mineo and Majumdar (1996) found that the maximum amount of mycorrhizae in two Quercus alba and Quercus rubra forests occurred in autumn. García (2001) found no significant difference amongst seasons in the number of mycorrhizal tips occurring in a Q. ilex stand, with maximum diversity in winter and summer and the minimum in spring and autumn.…”

Two study plots, burned and control, were established in autumn 1998 in a Quercus ilex forest located in northern Spain, part of which had been affected by a low intensity fire in 1994. Soil samples for ectomycorrhizae (ECM) were taken over a 3-year period in each study plot in spring, summer, autumn and winter. ECM morphotypes were identified and the relative abundance of each morphotype in each soil sample calculated, along with species richness, Shannon diversity index and percentage of mycorrhization in each soil sample. The relative abundance of certain ECM morphotypes differed between burned and control plots, and the percentage of mycorrhizal tips was significantly lower in the burned than in the control plot. Nevertheless, there were no significant differences in the diversity, species richness or species composition of the ECM community in the burned and control plots. The dominant ECM morphotypes in both stands were Cenococcum geophilum and several thelephoroid fungi. Sphaerosporella brunnea and Pisolithus tinctorius thrived especially in the burned plot, whereas three ectomycorrhizal morphotypes assigned to the genus Hebeloma were especially abundant in the control plot. There was no significant variation in the relative abundance of the ECM morphotypes between seasons, but ECM community species richness was highest in autumn and lowest in summer. The percentage of mycorrhizal tips reached a maximum in winter, with its minimum in autumn. Collection of samples over the 3-year period also enabled us to detect a significant increase in percentage of ECM colonisation in the burned stand over time.

“…Moreover, there is a lack of information on the seasonal and annual dynamics of the ECM community (Dahlberg et al 1997), as most of the studies undertaken so far are based on single collections of ECM; very few reports present data gathered over 1 year or more (Azul and Freitas 1999;García 2001;Mineo and Majumdar 1996).…”

“…In our declining stand, 64 ectomycorrhizal anatomotypes were found over a 2-year period, with ectomycorrhizal richness generally being seasonal and at its maximum in October, as observed by Mineo and Majumdar (1996) in two Quercus alba and Q. rubra forests.…”

“…VAM and ectomycorrhizal fungi were never observed simultaneously infecting the same portion of root. Beaded root tips (Grand, 1969; Mineo and Majumdar, 1996) were only rarely observed, and were not infected by either VAM or ectomycorrhizal fungi.…”

Summary• The influence of vesicular-arbuscular mycorrhizal ( VAM) host plants is reported on VAM infection of Quercus rubra seedlings, a predominately ectomycorrhizal species.• In a field experiment, Q. rubra seedlings were planted near Quercus montana and Acer rubrum (a VAM host) stump sprouts and near dead Quercus spp. stumps. In a subsequent glasshouse study, seedlings of Q. rubra were grown with or without VAM inoculum ( ± V) and with or without Sorghum bicolor ( ± S), a VAM host.• In the field experiment, seedlings planted near A. rubrum had greater VAM infection than other seedlings; ectomycorrhizal infection was greatest on seedlings near Q. montana . In the glasshouse experiment, VAM infection was increased in both extent (proportion of root length infected in roots of infected seedlings) and frequency (number of seedlings with infection) in the presence of S. bicolor . Seedling mass and N concentration were reduced in the + V treatment; however, these variables were not correlated with extent of VAM infection.• VAM infection of Q. rubra is greatly enhanced in the presence of VAM hosts in both field and glasshouse conditions. No evidence for positive effects of VAM infection on Q. rubra seedlings was found.
