Facies, architecture and genetic controls of carbonate ramp aprons development

Cool-water Carbonate Ramp Aprons (CRA) are depositional systems in which skeletal sand and gravel are redistributed basinwards on a ramp, off a shallow carbonate platform by tractive currents as a result of flow funnelling in between topographic highs. These deposits are different and should not be confused with the carbonate apron models proposed by of Mullins and Cook (1986) who describe either carbonate deep water turbiditic systems accumulated at the base of the slope or talus cones formed at the margins of carbonate build ups. A key example of CRA facies assemblages is represented by the Early Pleistocene, Favignana Calcarenite where bimodal depositional processes, occurring in a water…

Eustatic and oceanographic control on sedimentary evolution of middle-late Quaternary shelf margin-to-upper slope deposits on the Egadi Islands offsh…

2016

During the past decades a number of sequence stratigraphy studies illustrated how, during Quaternary, interaction between sea level changes and sediment supply controlled the depositional evolution along continental margins, giving a cyclic signature to the sedimentary infilling. However, as both deposition and erosion are processes ultimately controlled by balance between environmental energy and sedimentary influx, also the oceanographic regime takes part in controlling the sedimentary growth along the continental margin. This is exactly what occurs on physiographic settings as islands offshore areas, where bottom currents can be very energetic. In the western Sicily offshore, southwards …

Egadi Islands, COVID-19 Island Insight Series

2020

The COVID-19 Island Insights Series is an initiative spearheaded by the Strathclyde Centre for Environmental Law & Governance (SCELG) and the Institute of Island Studies (IIS) at the University of Prince Edward Island in collaboration with Island Innovation. The initiative brings together critical assessments of how specific islands around the world have performed during the COVID-19 pandemic and the extent to which their recovery plans can promote resilience and sustainability in the long term.

Effects of Caulerpa cylindracea on marine biodiversity

2017

The Mediterranean sea is an important hotspot for alien species. Following habitat loss, Invasive Alien Species (IAS) are considered to be amongst the most serious threats to biodiversity and natural ecosystem functioning. Among the IAS recorded in the Mediterranean sea, Caulerpa cylindracea Sonder, introduced from Australia and New Caledonia, has raised serious concern due to its negative impact on native communities. We provide some observations on the effects of the presence of C. cylindracea on the communities living along the coasts of the Island of Favignana (Egadi Islands, Marine Protected Areas).

Effects of NIS on Mediterranean marine ecosystems: the case study of Egadi Island MPA (Sicily, Tyrrhenian Sea)

2018

Habitat modification and loss, climate change and the introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural, past or present, range and outside of their natural dispersal potential) are considered to be the main threats to Mediterranean marine biodiversity and natural ecosystem functioning. NIS may become invasive (IAS = Invasive Alien Species) and may have significant environmental, socio-economic and human health impacts. The Mediterranean Sea is one of the major hotspots for NIS introductions, with the total for these species having almost reached the 1,000 figure (equivalent to ca. 6% of the total flora and fauna). NIS are entering the Mediterra…
