DISCUSSION RASPRAVA In two sessile oak stands in National Park Fruška gora studied in autumn, 26 different ECM fungal taxa were recorded in total, of which 14 taxa were observed only at the site Info center, nine taxa only at the site Brankovac and three ECM fungal taxa on both sites. However, an analysis of ectomycorrhizas across nine European countries at long-term and intensively monitored oak plots, showed that the average richness was 55, ranging from 24 fungal taxa in the Netherlands to 83 in Romania (Suz et al. 2014). In a temperate oak forest in northeast France, 75 fungal symbionts were recorded in 15 months (Courty et al. 2008). In two stands of Q. robur and Q. petrea in Austria, 46 and 38 ECM morphotypes were differentiated within 3 years (Kovacs et al. 2000). The number of ECM fungi recorded in our study was considerably lower in comparison to these studies. Differences in the obtained number of ECM taxa could be due to the lower number of soil samples taken in our study and the fact that sampling was done only in one season. Abundant species are prone to be present all year long, some species occur only in a particular season or month, while some ECM fungi are present all year long but with fluctuating abundance (Courty et al. 2008). On the other hand, species |
