Wood-inhabiting fungal responses to forest naturalness vary among morpho-groups
2021
The general negative impact of forestry on wood-inhabiting fungal diversity is well recognized, yet the effect of forest naturalness is poorly disentangled among different fungal groups inhabiting dead wood of different tree species. We studied the relationship between forest naturalness, log characteristics and diversity of different fungal morpho-groups inhabiting large decaying logs of similar quality in spruce dominated boreal forests. We sampled all non-lichenized fruitbodies from birch, spruce, pine and aspen in 12 semi-natural forest sites of varying level of naturalness. The overall fungal community composition was mostly determined by host tree species. However, when assessing the …
Ambienti umidi effimeri e naturalità del paesaggio in Sicilia
2009
I luoghi umidi temporanei sono ambienti acquatici che alternano periodicamente una fase d’invaso ed una fase secca ed ospitano espressive fitocenosi adattate a queste peculiari condizioni. Indagini condotte tra il 2003 ed il 2009 hanno consentito di individuare, in Sicilia, oltre 200 siti, costituiti generalmente da diverse pozze o piccoli stagni. L’estrema fragilità di questi habitat li rende molto vulnerabili a qualunque tipo di alterazione ambientale e pertanto risultano essere indicatori molto sensibili della pressione antropica sul territorio. Infatti, la conservazione di questi biotopi non può prescindere da una corretta gestione del contesto territoriale che li circonda. Il presente …
G.I.S. context analysis for environmental recovery suitability evaluation
2009
The attributes of every single patch in a land mosaic constitute the database that landscape ecologists use for processing and analysis. Nonetheless spatial and ecological relationships between adjacent patches can play a key role in understanding the overall functionality of land mosaics. Defining the ecological role of a single tessera within an ecosystem is not possible if that patch is regarded as an insular element; on the other hand global analysis on the entire land mosaic would grant just a small amount of new information on each tessera and none on its functional role. To recognize areas susceptible of improvement through environmental recovery and to define priorities for interven…
