Seasonal patterns in butterfly abundance and species diversity in five characteristic habitats in Sites of Community Importance in Sicily (Italy)

2015

Sicily (Italy) is one of the richest European regions in animal biodiversity. Butterflies offer good opportunities for studies on biodiversity , population and community ecology. Many species are strictly seasonal, preferring only a particular set of habitats. Five typical Mediterranean habitats: olive grove (conducted following organic farm management), mixed wood, ampelodesmos prairie (with dominance of Ampelodesmos mauritanicus), Mediterranean shrub and shrub at the coastal areas, were monitored for diversity and seasonal patterns in butterfly communities for 2 years. All habitats were inside protected areas indicated as Sites of Community Importance. Butterfly species richness was highe…

Il mese di produzione influenza la qualità di formaggi tipici?

2022

Il settore lattiero-caseario mediterraneo rappresenta una delle più importanti attività legate al lavoro delle terre montane e marginali e alla produzione di prodotti tipici e di qualità. Un prodotto “tipico” è il risultato di diversi fattori strettamente legati all’origine geografica e alle tradizioni sociali e culturali dell’area di produzione. Tali prodotti sono da sempre uno strumento per valorizzare la biodiversità, la cultura e l’economia di definite aree mediterranee. L’Unione Europea riconosce ufficialmente questa diversificazione di prodotto attraverso l’attribuzione di marchi di qualità a denominazione di origine protetta (DOP) e a indicazione geografica protetta (IGP). Nella poli…

La struttura spaziale della successione secondaria delle piante legnose in un pascolo mediterraneo

2018

Negli ultimi decenni molte aree agricole e pastorali dell’Europa e del Mediterraneo sono state abbandonate o hanno subito importanti cambiamenti nell'intensità dell'uso antropico, determinando processi di successione secondaria a volte anche rapidi dopo secoli di attività agricola determinando in alcuni casi un forte cambiamento nelle proporzioni tra aree agricole e aree forestali in molti paesi tra cui l’Italia. Nonostante molti studi abbiano descritto gli aspetti fitosociologici e strutturali di questa successione secondaria in diverse aree del Mediterraneo, la maggior parte di questi studi sono stati condotti su larga scala, con pochi dati disponibili riguardo alla struttura spaziale svi…

Calculation of Energy Performance Indices of Daylight Linked Control Systems by Monitored Data

2017

The actual performances of Building Automation systems are often lower than the ideal ones. In order to investigate the actual performance of a Building Automation system for lighting control, a large stock of collected data, including indoor illuminance and absorbed electric power, have been presented and analysed in this paper. The measures have been taken during one year, in a laboratory located at the University of Palermo, where different lighting control systems, produced by two different manufacture companies, have been installed. As demonstrated in literature, many factors affecting energy savings’ evaluation in lighting control systems are the position and the typology of the senso…

Automatic classification of acoustically detected krill aggregations: A case study from Southern Ocean

2022

Acoustic surveys represent the standard methodology to assess the spatial distribution and abundance of pelagic organisms characterized by aggregative behaviour. The species identification of acoustically observed aggregations is usually performed by taking into account the biological sampling and according to expert-based knowledge. The precision of survey estimates, such as total abundance and spatial distribution, strongly depends on the efficiency of acoustic and biological sampling as well as on the species identification. In this context, the automatic identification of specific groups based on energetic and morphological features could improve the species identification process, allo…

MR3377117 Reviewed Giordano, Paolo; Nigsch, Eduard A. Unifying order structures for Colombeau algebras. Math. Nachr. 288 (2015), no. 11-12, 1286–1302…

2015

Colombeau Algebras are differential algebras of generalized functions (that include the space of distributions) that are defined using a quotient set procedure involving particular classes of nets in a basic space E = (C∞(Ω))A, where Ω is an open subset of R n and A is an index set. The choice of such nets depends mainly on their asymptotic behavior over a suitable index set A. Many variants of Colombeau Algebras existing in the literature occur mainly due to different choices of the index set (and to the choice of asymptotic behavior). A purpose of this paper is to formally unify some of these algebras, redefining the asymptotic behavior on an abstract (pre-ordered) set of indices, and gen…
