Archeologia fluviale
2020
Palermo sta sul mare, ma ha un rapporto difficile con il mare. La questione sorge, nel XVII secolo, al momento della costruzione dei Quattro Canti di Città o piazza Vigliena, quando l’asse di fondazione fenicio (il Cassaro, con giacitura EO) venne intersecato da una strada ortogonale (via Maqueda, con giacitura NS) capace di cancellare - con la formazione di un centro - la relazione che si era istituita, nel tempo, tra monti e mare attraverso la città. Da quel momento in poi l’espansione, all’interno della Conca d’oro, avvenne prevalentemente verso Nord, allontanando la città sempre di più dalla linea di costa a causa, anche, di Monte Pellegrino e di Pizzo Sella, due promontori abbandonati …
Prehistoric Settlement and Population in the Madonie Mountains. New Data from the Archaeological Survey
2010
The aim of the Madonie research project is to analyse mobility strategies and the use of a mountainous territory by relating geomorphologic features, raw material sources and landscape to the prehistoric settlement. For this purpose we planned an intensive and systematic survey of sample areas, selected on geo-morphological, altimetric and archaeological criteria, correlated to a palaeoenvironmental investigation based on the study of palynological sequence samples coming from wet areas of the Madonie territory and from archaeological deposits. Le projet de recherche sur la Madonie analyse les stratégies de mobilité et l’exploitation du territoire de montagne, en reliant les caractéristique…
La 'Terra di mezzo' tra Siracusa e Augusta. Dalle poleisgreche alla citta lineare
2019
[SPA] El 'Dipolo urbano' de Siracusa·Augusta es un área estratégica para el futuro del sureste de Sicilia. Es un palimpsesto antrópico caracterizado por la presencia de un delicado paisaje natural y agrícola, sitios arqueológicos extraordinarios. contextos urbanos poblados y una industria petroquímica. El área geográfica es la zona costera incluida entre Augusta y Siracusa: una porción del territorio caracterizada por la presencia de calas y puertos naturales, limitada al oeste por la meseta calcarenítica de las montañas Climiti. En este palimpsesto tan degradado. la Escuela de Arquitectura de Siracusa ha estado estudiando posibles estrategias de recuperación y recualificación. A partir de …
Hypercalcified sponges from the Upper Triassic (Norian-Rhaetian) reefs of Sicily
2015
The sponge-dominated Upper Triassic (Norian-Rhaetian) reefs of Sicily yielded the most abundant hypercalcified sponge taxa compared with other time equivalent reefs in the world. Chambered sponges (“Sphinctozoa”) are the most abundant group among the hypercalcified sponges. All together almost 150 species of hypercalcified sponges (including sphinctozoans, inozoans, chaetetids, disjectoporids and spongiomorphids) were recognized in the Norian-Rhaetian reefs occurring in different localities in Sicily. 93 species (30 new, 28 as sp. indet.) of sphinctozoans, belonging to 18 families (2 new: Polytubithalamiidae, Globucatenulaiidae) and 35 genera (4 new: Globucatenula, Polytubithalamia, Rostros…
Pomological and quality traits of mulberry (Morus spp.) germplasm from Gorno Badakhshan in the Western Pamir
2017
The local fruit biodiversity can represent a good opportunity to maintain the agriculture and to develop economies in "marginal" territory such as those in the mountain rural areas. The genetic diversity of the Morus spp. is little known in the Western Pamir mountains, so that the objective of the present study was to improve the knowledge of the polymorphism of the species in the different poorly explored Tajik valleys by investigating the main quantitative and qualitative traits. Materials and methods - Six selected sites of the Gorno Badakhshan Autonomous Oblast (GBAO) region were investigated through field measurement on morphological traits of mulberry trees (both from wild and cultiva…
1400 years of man-environment interactions and soil evolution in the Saint-Mont mountain (Remiremont, Vosges)
2021
International audience; The SolHoM(a) project aims at determining the degree of landscape anthropisation in the Fossard massif (Remiremont, Vosges, France) by estimating the impact of past human occupations on current soils. Nowadays, a forest covers this relatively inhospitable mountain (hard climate, steep slopes, acid soils ...), but some remains suggest human presence for at least 1400 years.The Saint-Mont is a variscan orogenic granitic summit (height 672m) with valuable preserved archaeological relics, located south of the Fossard. At the top was founded the monasterium Habendum (from the 7th century to the French Revolution), which potentially comes after a late-antic castrum.Further…
Fern-dominated Rock Plant Communities of Tajikistan (Middle Asia)
2015
The results of phytosociological research conducted on the fern vegetation of rock crevices and clefts of the Pamir-Alai Mountains in Tajikistan are presented. During field surveys done in 2010–2013, 78 phytosociological relevés were sampled. Plant species were recorded according to the Braun-Blanquet cover-abundance scale. A synopsis of the fern communities of the montane and high altitude zones in Tajikistan is proposed. In the examined vegetation plots, species of 9 ferns, 58 angiosperms and 13 mosses were recorded. The most frequent ferns were: Cystopteris fragilis, Cheilanthes persica, Asplenium ruta-muraria, Asplenium ceterach, Adiantum capillus-veneris and Cryptogramma stelleri. Six …
Brassica trichocarpa (Brassicaceae), a new species from Sicily
2013
A new species of Brassica from Sicily, namely B. trichocarpa, is described and illustrated. This suffrutex was found on a calcareous peak of a mount near Palermo, where it is represented by a single population occupying a really small surface. It is well differentiated from the other perennial species belonging to B. sect. Brassica mainly in having hairy ovary and very short, thickened, hairy, not torulose fruits. Its relationships and taxonomical position within this group are examined too. An analytical key of the current taxa belonging to the genus Brassica sect. Brassica is also provided.
Human and animal fascioliasis in andean regions of argentina: lymnaeid vectors and livestock reservoirs
2018
La fascioliasis es una enfermedad parasitaria zoonótica causada en América por Fasciola hepatica. Produce serias pérdidas económicas a la ganadería y es un importante problema en salud pública a nivel mundial. Las más altas prevalencias en humanos se hallan en regiones andinas. La especie de lymnaeido vector involucrada condiciona el escenario epidemiológico. En Argentina existía gran controversia acerca de las especies de lymnaeidos vectores presentes. Además de los bovinos, escasos estudios han considerado el rol que cumplirían otras especies domésticas y silvestres como reservorios. La fascioliasis humana ha sido considerada una enfermedad de escasa relevancia. El objetivo del presente t…
A Synopsis of the Genus Stipa (Poaceae) in Middle Asia, Including a Key to Species Identification, an Annotated Checklist, and Phytogeographic Analys…
2020
The genus Stipa L. comprises over 150 species, all native to the Old World, where they grow in warm temperate regions throughout Europe, Asia, and North Africa. It is one of the largest genera in the family Poaceae in Middle Asia, where one of its diversity hotspots is located. However, identification of Middle Asian Stipa species is difficult because of the lack of new, comprehensive taxonomic studies including all of the species recorded in the region. We present a critical review of the Mid-Asian representatives of Stipa, together with an identification key and taxonomic listing. We relied on both published and unpublished information for the taxa involved, many of which are poorly known…
