Bias correction of dynamically downscaled precipitation to compute soil water deficit for explaining year-to-year variation of tree growth over north…
2017
This paper documents the accuracy of a post-correction method applied to precipitation regionalized by the Weather Research and Forecasting (WRF) Regional Climate Model (RCM) for improving simulated rainfall and feeding impact studies. The WRF simulation covers Burgundy (northeastern France) at a 8-km resolution and over a 20-year long period (1989–2008). Previous results show a strong deficiency of the WRF model for simulating precipitation, especially when convective processes are involved. In order to reduce such biases, a Quantile Mapping (QM) method is applied to WRF-simulated precipitation using the mesoscale atmospheric analyses system SAFRAN («Système d'Analyse Fournissant des Rense…
Diachronic Analysis of Beech Forest in the Nebrodi Park (Northern Sicily)
2017
A comparison between the current surface of Beech forest in the Nebrodi Park (Northern Sicily) with the measurements performed in the past is here reported. 12.854 hectares of Beech forest were recognized against 10.336 hectares of 1959 with a percentage increase of 24.37%. The increase of forest is mainly due at the change of land use through a better forest management and grazing.
Production and turnover of organic matter in three southern European Fagus sylvatica L
1999
Above-ground biomass, litterfall and litter accumulation and decomposition at the soil surface were studied within three Mediterranean beech forests from Italy, France and Spain in order to better understand the recycling of elements associated with the turnover organic matter Above-ground tree biomass amounted to 131.9 Mg ha-1 at Etna (Italy), 134.2 Mg ha-1 at Sierra de la Demanda (Spain) and 223.9 Mg ha-1 at Mont Lozère (France). The highest amount of total litterfall was observed at Sierra de la Demanda (4.7 Mg ha-1 year-1), followed by the Mont Lozère (4.4 Mg ha-1 year-1) and Etna (3.9 Mg ha-1 year-1). Total organic matter accumulated on the soil surface in the three beech forests amoun…
Le variazioni delle superfici a faggio nel Parco delle Madonie (Sicilia): effetto del cambiamento climatico o della diversa pressione antropica?
2019
Le faggete siciliane sono di rilevante interesse fitogeografico ed ecologico perché vegetano al limite meridionale dell’intero areale di distribuzione europeo della specie. Il faggio in Sicilia caratterizza nettamente il paesaggio montano dell’Isola, raggiungendo il limite superiore della vegetazione arborea. L’areale siciliano ricopre una superficie di circa 16.000 ha, legato alle principali vette e alle alte pendici dei Monti Madonie, Monti Nebrodi ed Etna. Recenti studi hanno evidenziato che il 40% circa delle faggete siciliane sono potenzialmente a rischio a causa delle condizioni climatiche estreme. Contestualmente, alcune ricerche hanno avanzato l’ipotesi di un incremento delle superf…
Leptocorticium gloeocystidiatum sp. nov. (Basidiomycota), a new corticioid fungus from Sicily, Italy
2014
A new corticioid species, Leptocorticium gloeocystidiatum is described from Sicily, Italy. It is characterized by a resupinate, buff-coloured basidiome and microscopically by the presence of filiform leptocystidia, gloeocystidia, dendrohyphidia, and small ellipsoid, smooth basidiospores, non-reacting in Melzer's reagent. The species is compared with closest relatives. A key to the accepted species of Leptocorticium is provided.
