SOFIA: a decision support System for the Optimization of the biomass supply chain and Forest Integrated management in protected areas

2019

A decision support System for the Optimization of the biomass supply chain and Forest Integrated Management in protected areas (SOFIA) is presented. All functionalities have been developed in Python language embedded in the open-source QGIS 3.6 software. Two models were implemented with an approach and methodology based on free and open source software (QGIS, GRASS, SAGA, GDAL). The main aim of SOFIA is to support the Madonie Regional Natural Park authority and forest managers in decision-making processes to assess the costs and benefits in the energy production from residual agro-forestry biomass, as well as for determining the optimum plant size (and power) for energy and heat production …

In search of the most mysterious orthopteran of Europe: the Reed cricket Natula averni (Orthoptera: Gryllidae).

2011

In the last few years a lot of new information has become available on Natula averni. As the common name we propose Reed cricket, because the species was found almost exclusively in reed beds. Recent findings show that this species is more abundant than previously thought. The species can easily be found with knowledge of distribution, habitat and song, all described in this publication. Nevertheless a lot of questions remain about the taxonomy. We hope that information gathered after this publication will help us to reveal the proper identity of reed crickets in Europe.

OPTIMA Newsletter 42(1-2)

2015

OPTIMA Newsletter nº 42 continues the standard followed in the previous issues. The Newsletter is divided into two parts, the first with the News and the second with the Notices of Publications. The first section regarding news has became gradually thinner due to the fast and cheap channel represented by e-mail. The news here reported are only those that it makes sense to also produce as hard copy. Short news from OPTIMA Commissions are included, limited to those that reported activity in 2013, 2014 and beginning of 2015.

Leaf anatomy in Tamarix arborea var. arborea (Tamaricaceae)

2012

Previously unpublished data on the macro- and micro-morphological features of the leaf of Tamarix arborea var. arborea are provided. Clear differences in salt gland localization and type of venations were observed in the investigated species compared to other Tamarix species, thus emphasizing the taxonomic value of the leaf within this genus.

First finding in Sicily of Bidens subalternans (Asteraceae)

2017

It is reported the presence in Sicily of a new alien species destined to a progressive further spread in the Island. It is Bidens subalternans DC., an annual asteracea of American origin, already known in other Italian regions (Friuli Venezia Giulia, Lombardia, Marche, Lazio and Campania) and in other European countries (Belgium, Corse, Croatia, Cyprus, France, Germany, Great Britain, Montenegro, Republic of Serbia, Slovenia, Spain, Switzerland). The new locality, in Sicily, occurs along the roadside Monreale – Pioppo, south of the city of Palermo. In this station, B. subalternans is found together with B. pilosa subsp. minor and other indigenous and exotic nitrophilous taxa. The population…

The first case of spontaneous regeneration of Araucaria columnaris in Europe is reported. Data are given on the taxon and on the Sicilian site where A. columnaris - native to New Caledonia (Australia) - tends to spread autonomously.

Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)

2015

Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…
