| Sumario: | The aim of this work was to study and describe fungal communities regarding their productivity, diversity and species composition in Mediterranean areas covered by Pinus pinaster. The objective was to determine how fungal communities were affected by the different edaphoclimatic conditions that characterized three different habitats. Sporocarps were collected and identified from 100 m2 transects during the autumn seasons from 2006 to 2012. Data analysed were originated from three different sites characterised by a siliceous soil treatment, an inner dune and a calcareous soil type. Total fungal production and richness were much higher in the siliceous and calcareous forests than in the inner dune type. The results were similar when analysing production of mycorrhizal taxa and diversity index for saprotrophic fungi. On the other hand, the fungal taxa composition was mainly correlated with climatic variables such as precipitation and temperature. Moreover nitrogen and potassium soil contents significantly affect the distribution of taxa for both saprophytic and mycorrhizal functional groups. The results showed a broad range of ecological taxa such as Lycoperdum perlatum, Russula torulosa and species within genus Galerina and Mycena. Moreover, other species showed a great specificity according to environmental conditions. Thus, all the species included within Macrolepiota genera were collected in the calcareous soils whereas Laccaria laccata and L. bicolor were exclusively associated with higher precipitations and contents of nitrogenous in the siliceous plots. The results showed a noticeable high fungal production and diversity associated to P. pinaster in extreme Mediterranean conditions which could represent ecological and economical implications to be taken into account by forest managers in order to add value to these forests. |
