The ectomycorrhizal community of Abies nebrodensis: preliminary results
2016
Abies nebrodensis (Lojac.) Mattei is a Critically Endangered forest tree included in Appendix I of the Bern Convention and as a priority species in Annexes II and IV of the Habitats Directive [1]. In situ and ex situ conservation strategies [2] and, more recently, a LIFE Natura project [3] allowed a marked improvement of health conditions of trees and of seedlings renewal. A first attempt to characterize the ectomycorrhizas of A. nebrodensis was carried out by Venturella & Rambelli [4]. In the frame of the activities of the II National Workshop of Ectomycorrhyza (Palermo, 2015), this paper reports the preliminary investigation carried out on the ectomycorrhyzal community of A. nebrodensis i…
Diversità della comunità ectomicorrizica presente in un impianto artificiale di conifere alloctone in Sardegna
2014
Nel presente contributo sono riportati i risultati di uno studio sulla diversità della comunità fungina ectomicorrizica (ECM) presente in un impianto artificiale di conifere alloctone (Abies alba Mill., Pinus nigra Arnold e Cedrus atlantica (Endl.) Manetti ex Carrière), in cui è presente rinnovazione di A. alba e di Quercus ilex L., unica specie vegetale arborea autoctona presente nell’ambiente di studio. L’area d’indagine è localizzata a Tempio Pausania (Sardegna), sul monte Limbara in località Madonna della Neve (1262 s.l.m). Al suo interno sono stati individuati 5 plot omogenei, ed in ciascuno di essi sono stati prelevati frammenti radicali dalla base di esemplari adulti di A. alba, P. n…

Nitrogen-fixing cushion Astragalus siculus modulates soil fertility, microclimate, plant facilitation, bacterial and fungal microbiota along an eleva…
2023
Question: Cushion-forming vascular plants are adapted to alpine environments and act as ecosystem engineers by moderating microclimate and creating a fertility island under their canopy. Most of the available studies on cushion ecology have been devoted to plant facilitation, but none used a holistic approach that considers the response of co-existing plant species with other key ecosystem players. Here, we quantified the biogenic effect and facilitation capacity of Astragalus siculus, a spiny nitrogen-fixing cushion plant, and test the hypothesis that the facilitation effect would increase with elevation as stress gradient.Location: Mount Etna, the highest active volcano in the Mediterrane…
