Sea–land geology of Marettimo (Egadi Islands, central Mediterranean sea)

2016

We present a 1:10,000 scale geological map of Marettimo Island and its offshore (Egadi Archipelago, central Mediterranean Sea). The map was achieved by integrating a new geological survey with data from recent, marine, geological and geophysical surveys acquired along the adjacent continental shelf. The island is composed of a Mesozoic, mostly carbonate platform succession, which is overlain by continental to coastal marine Quaternary deposits. Extensional tectonics have affected the carbonate platform since the Late Triassic producing an initial increase of accommodation space that was filled by interbed breccias, marls and calcareous marls. During the Jurassic, a NE-SW-directed normal fau…

Fish functional traits are affected by hydrodynamics at small spatial scale

2016

The Mediterranean damselfish Chromis chromis is a species with a broad distribution found both in the Mediterranean Sea and Eastern Atlantic as far south as the coast of Angola. We hypothesized that the species may have significant functional morphological plasticity to adapt along a gradient of environmental conditions. It is a non-migratory zooplanktivorous species and spends the daytime searching for food in the middle of the water column. Therefore, local hydrodynamics could be one of the environmental factors affecting traits of C. chromis with repercussions at the population level. We compared the body condition, individual growth and body shapes of damselfish collected under two diff…

¿Marxismo o diferenciación social?

2018

Para la sociología, el debate con el marxismo forma uno de los telones de fondo intelectuales y prácticos en el surgimiento de esta joven ciencia durante el siglo xix. Uno de los puntos más interesantes de esta disputa trata del grado necesario de diferenciación de las categorías analíticas para comprender los mecanismos básicos de la sociedad. La capacidad y la necesidad de reducir la compl ejidad que requiere cada ciencia, si quiere ll egar a un nivel de generalización que permita la acción social, se contrapone a una diferenciación analítica que tenga en cuenta la máxima cantidad posibl e de elementos relevantes para la comprensión de lo social. El presente artículo alumbra las relacione…

The Colour Plan of Egadi Islands

2018

The Egadi Islands, at the western end of Sicily, preserve a peculiar architectural and environmental heritage. The work of people – related to tuna fishing, stone extraction and agriculture – has created, over time, an exceptional landscape. The nature, colour and texture of the local stone have given shape to a traditional architecture that, today, risks to disappear and to be replaced by new anonymous buildings. Furthermore, the pressure of tourism threatens to damage this delicate balance established, over centuries, between people and environment. Therefore, the Local Administration decided to adopt a Colour Plan to manage the inevitable processes of territorial transformations. The Arc…

Realistische Abrechnung mit Präexistenz und Reinkarnation. Julius von Heydens Gesprächsnovelle "Das Geheimnis der Reminiszenz"

2019

Heyden's story takes up the belief in reincarnation as an element of German idealism, as well as liberal ideas of social equality to critically disprove both of them.

An additional record of Kyphosus vaigiensis (QuoyGaimard, 1825) (Osteichthyes, Kyphosidae) from Sicily clarifies the confused situation of the Medite…

2015

The lowfin chub, Kyphosus vaigiensis, is reported for the first time off Favignana Island, Sicily, central Mediterranean Sea. The specimen was identified on the basis of morphometric and meristic characters as well as mitochondrial DNA sequences (COI and 16S-rDNA). Two, perhaps three, Kyphosus species - K. bigibbus, K. sectatrix and K. vaigiensis - have been occasionally recorded in the Mediterranean. These species occur both in the Atlantic and Indo-Pacific regions but it is likely they entered the Mediterranean through the Strait of Gibraltar. However, it is unclear whether they have established reproductive native populations in the Mediterranean.

First record of Aplysia dactylomela (Opisthobranchia: Aplysiidae) from the Egadi Islands (western Sicily)

2014

The alien mollusc Aplysia dactylomela is recorded for the first time from the Egadi Islands marine protected area (western Sicily). This species has been widely reported in the Mediterranean and has established populations in Sicily. The presence of a few specimens let us suppose that its occurrence in this area is a recent event and that soon new populations will be sighted in the whole Egadi Islands and on the western and southern coasts of Sicily.

Palaeogeographical evolution of the Egadi Islands (western Sicily, Italy). Implications for late Pleistocene and early Holocene sea crossings by huma…

2019

Abstract The continental shelf morphology offshore of western Sicily suggests that during the Last Glacial Maximum (LGM, 20 ka cal BP), two of the Egadi Islands, Favignana and Levanzo, were connected to Sicily by a wide emerged plain, while Marettimo was only separated from the other islands by a narrow channel. We studied the relative sea-level variation from the LGM until today, focussing on two important time slices: the Mesolithic (9.5–13 ka cal BP) and the Neolithic (6.5–7.5 ka cal BP). In this research, we discuss a sea-level rise model by means of geomorphological, archaeological and geophysical observations and new radiocarbon dating of marine and terrestrial fossil fauna. The resul…
