Boschi nel paesaggio, paesaggio dei boschi. Risorse forestali nel paesaggio tradizionale.
2011
La variabilità e la ricchezza di caratteri ambientali di un territorio rappresentano il substrato potenziale sul quale le diverse influenze culturali nel corso del tempo hanno modellato forme ed espressioni diverse di paesaggio. Affinché ci sia ricchezza e variabilità di paesaggi, un territorio sufficientemente ampio deve quindi mostrare variabilità in termini fisiografici, climatici, litologici, pedologici, vegetazionali, dell’uso del suolo agrario, storici, culturali.
Paracamelichnum Jumillensisn.ichnogen. n.ichnosp., Upper Miocene Camelidae Ichnites from the Hoya de la Sima site (Murcia, Spain)
2009
In the proximity of Jumilla (Murcia, Spain) there is a site called Hoya de la Sima with mammal footprints dating from the Upper Miocene. This site is an old gypsum quarry where footprints of Hipparion, Pecoripeda, Carnivora, Ursidae, and Proboscidea were discovered. While the site was being cleaned and conditioned after the discovery to protect the prints, Camelidae and other prints were unearthed and are currently being studied. The description of the Camelidae ichnites demonstrates that these belong to a new ichnogenera, produced by the prints of Paracamelus. The grouping of trackways is congruent with the gregariousness of these animals and with the concentration observed in similar site…
Stroboscopic XMCD-PEEM Imaging
2007
Abstract This article summarizes recent results on magnetization dynamics obtained with time-resolved photoemission electron microscopy (PEEM) using X-ray magnetic circular dichroism as contrast mechanism. Time resolution is performed by a stroboscopic technique that is exclusively sensitive to reversible processes, but offers a very high time resolution only limited by the X-ray pulse width. A time resolution of 20 ps in combination with a lateral resolution of 100 nm has been achieved.
Mammoth remains from the Opole area, southwest Poland
2016
Isolated skeletal remains of woolly mammoths, found in the Opole region, are described and illustrated. Most of these were recovered in the first half of the twentieth century; they are now deposited in several museum collections but have not yet been described in detail, nor illustrated. Recent discoveries in the area were the prime trigger for the present review of previously collected material. A summary of current knowledge of all finds of mammoth remains from the Opole area is the main aim of this note, inclusive of a brief history of research. In addition, a single radiocarbon dating has been performed. All skeletal elements, i.e., molars, pelvis, femur, scapula, jaw, tusks and cement…
Pinus halepensis M. versus Quercus ilex subsp. Rotundifolia L. runoff and soil erosion at pedon scale under natural rainfall in Eastern Spain three d…
2017
Abstract Afforestation aims to recover the vegetation cover, and restore natural ecosystems. The plant species selected for restoration will determine species richness and the fate of the ecosystem. Research focussing on the impact of vegetation recovery on soil quality are abundant, especially on fire affected land and where rehabilitation, afforestation and restoration projects were carried out. However, little is known about how different plants species affect soil erosion and water losses, which are key factors that will impact the fate of the afforested land. Aleppo pine (Pinus halepensis M.) is the species commonly used for afforestation in the Mediterranean and is very successful whe…
Thorny-Headed Worms (Acanthocephala): Jaw-Less Members of Jaw-Bearing Worms That Parasitize Jawed Arthropods and Jawed Vertebrates
2021
Stem-acanthocephalans in the millimeter range might already have parasitized mandibulates in the Cambrian, while larger body sizes presumably evolved along with the upward-inclusion of gnathostome hosts. The characteristic morphology of modern acanthocephalans including the mostly hooked attachment organ (proboscis) should have emerged in the same context. Due to their rigidity, acanthocephalan hooks and copulatory caps are candidates for fossilization, but soft-tissue preservation might also have occurred under exceptional circumstances. Nonetheless, eggs represent the only ancient remains assigned to acanthocephalans to date. These were mostly retrieved from dried mammalian coprolites of …
Constructional morphology and mode of attachment of the trunk ofCorynosoma cetaceum (Acanthocephala: Polymorphidae)
1999
Dead specimens of Corynosoma cetaceum were used to describe the trunk musculature of this species and to infer the use of the trunk as a secondary holdfast. Inferences were based on trunk muscle arrangement, changes in trunk shape, size and distribution of spines, and geometry of tegument thickness. The foretrunk of C. cetaceum is swollen and forms a spiny disk that is bent ventrally. The disk is flattened by several groups of muscles not described previously, which seem able to finely adjust the disk surface over the substratum. Disk attachment appears to be accomplished by two dorsal neck retractor muscles specialized in pulling the anchored proboscis into the foretrunk. This mechanism ha…
Caratteristiche dei boschi della Sicilia.
2011
La superficie forestale della Sicilia, inventariata secondo le definizioni di “bosco” e “altre aree boscate” della FAO (FRA 2000), comprende formazioni molto diversificate in termini di composizione floristica del soprassuolo, della sua densità e struttura, del suo sviluppo potenziale, dell’origine, del grado di naturalità e della coltura praticata. Le categorie inventariali riconducono le diverse formazioni forestali entro insiemi relativamente omogenei in termini di copertura arborea e arbustiva, sviluppo potenziale e, nel caso degli impianti di arboricoltura, di particolare forma gestionale.
Salvatore Boscarino : la didattica e il dibattito sul restauro dei monumenti in Italia (1975-2000)
2018
Il volume Salvatore Boscarino La didattica e il dibattito sul Restauro dei Monumenti in Italia 1975-2000 vuole sintetizzare il proficuo dibattito intercorso fra i docenti di Restauro dei Monumenti in Italia, nel periodo compreso fra il 1975 e la fine del Ventesimo secolo, e sottolineare l’impegno, anche nella didattica, di uno dei suoi protagonisti: Salvatore Boscarino (1925-2001). La ricerca, temporalmente inscritta tra l’anno 1975 (anno della vincita del concorso per professore ordinario di Restauro dei monumenti di Boscarino) e il 1998 (anno in cui Boscarino seguì la sua ultima tesi di laurea a Palermo), quale concatenazione di più temi, riferisce sul dibattito fra gli stessi docenti di …
