Life‐form diversity across temperate deciduous forests of Western Eurasia: A different story in the understory
2021
[Aim]To analyse the biogeographic patterns of Temperate Deciduous Forests (TDFs) in Western Eurasia based on different life-forms and forests layers and explore their relationships with the current climate, Last Glacial Maximum (LGM) climate and topography.
Life forms, life strategies and ecological indices of bryophytes for bioindication in wood areas: a case of study in the "Bosco della Ficuzza, Rocca …
2015
Life forms, life strategies and ecological indices of bryophytes which live in evergreen and deciduous Quercus woods as well as in a Pinus halepensis artificial system within the "Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere e Gorgo del Drago" Oriented Nature Reserve are analysed and compared. The study highlights that in the same local climatic conditions the Quercus and Pinus trees select different bio-ecological types in the bryophyte communities. They appear to be especially useful to detect physionomic-structural differences in the woods, integrating the information provided by the ecological indices
Alien plant invasions in Mediterranean habitats: an assessment for Sicily
2021
AbstractLevels of plant invasions in different habitat types were assessed in several regional studies, but few of them were from the Mediterranean. Here we compare the levels of vascular plant invasion across habitats and plant communities of Sicily. We used a large dataset of plant species presences/absences in vegetation plots to analyze the invasion patterns across habitats considering biogeography, life form and phenology of alien plants. Vegetation plots were classified based on the EUNIS classification of European habitats. The invasiveness of each species was expressed in terms of its absolute and percentage frequency. Representation of different life forms and phenological patterns…
Forme di vita / forme del corpo: studi di caso.
2019
La nozione di “forma di vita”, in semiotica, appare al tempo stesso evidente e confusa. Vagliata e discussa da parecchi anni, viene utilizzata da molti studiosi in più occasioni e con diversi scopi. Funziona come un tipico termine ombrello. Parallelamente, molti nodi problematici relativi alla scienza della significazione, pur avendo palesi tangenze con tale nozione, sembrano volerne o poterne fare a meno, dichiarandola in contumacia fuori corso.
