Sicily: the island that didn't know to be an archipelago (original) (raw)
2018, Berichte der Reinhold-Tüxen-Gesellschaft
Recent geological studies demonstrated that most of Sicily was still under water during lower Pliocene, with the exception of the NE and the SE corners of the island (Peloritani Mts and Hyblaean Plateau, respectively). This geological evidence, so far not considered sufficiently by the scholars of the Sicilian flora, poses many still open questions on how and where many ancient lineages and Palaeogene relicts, currently found on the island, managed to survive. Purpose of this paper is to review the potential significance of isolation and ecological differentiation for the local floristic diversity and the evolution of narrow endemism in the Sicilian flora. In particular, the following drivers of Sicilian floristic patterns are considered: geographical segregation and age of the Sicilian terrains; climate variability and heterogeneity; geological patchiness; human influence on habitat fragmentation.

Botanical Escursions in Central and Western Sicily
A comprehensive guide for botanical excursions in Central and Western Sicily, including 24 itineraries described in every detail and illustrated by maps and photographs of the excursion sites. The book illustrates, as well, the whole flora of Sicily (more than 3000 species of vascular plants) arranged in synoptic tables and provides an up-to date syntaxonomy and bibliography of the phytosociological classification of the Sicilian vegetation. The guide was prepared for the 60th Annual Symposium of the International Association for Vegetation Science, held in Palermo, Italy, on June 20–24, 2017. The symposium saw 393 participants from 56 States across 5 continents.
Three Millennia of Vegetation, Land-Use, and Climate Change in SE Sicily
Forests
This study presents the first Late Holocene marine pollen record (core ND2) from SE Sicily. It encompasses the last 3000 years and is one of the most detailed records of the south-central Mediterranean region in terms of time resolution. The combined approach of marine palynology and historical ecology, supported by independent palaeoclimate proxies, provides an integrated regional reconstruction of past vegetational dynamics in relation to rapid climatic fluctuations, historical socio-economic processes, and past land-use practices, offering new insights into the vegetation history of SE Sicily. Short-term variations of sparse tree cover in persistently open landscapes reflect rapid hydroclimatic changes and historical land-use practices. Four main phases of forest reduction are found in relation to the 2.8 ka BP event, including the Late Antique Little Ice Age, the Medieval Climate Anomaly, and the Little Ice Age, respectively. Forest recovery is recorded during the Hellenistic an...
Archaeogenetics and Landscape Dynamics in Sicily during the Holocene: A Review
Sustainability, 2021
The Mediterranean islands and their population history are of considerable importance to the interpretation of the population history of Europe as a whole. In this context, Sicily, because of its geographic position, represents a bridge between Africa, the Near East, and Europe that led to the stratification of settlements and admixture events. The genetic analysis of extant and ancient human samples has tried to reconstruct the population dynamics associated with the cultural and demographic changes that took place during the prehistory and history of Sicily. In turn, genetic, demographic and cultural changes need to be understood in the context of the environmental changes that took place over the Holocene. Based on this framework, this paper aims to discuss the cultural and demographic dimension of the island by reviewing archaeogenetic studies, and lastly, we discuss the ecological constraints related to human peopling in times of change in landscapes that occurred on the island...

This paper illustrates the botanic heritage of Parche di Bilello, a site located in the municipality of Castelvetrano. The study area hosts several woodland fragments dominated by Olea europaea var. sylvestris, Quercus suber and Quercus ilex, respectively. According to historical data, these nuclei represent the last remnants of an open forestland which covered a much wider coastal area between Mazara del Vallo and Sciacca until the end of Middle Age. Phytosociological relevés were focused on these forest nuclei, probably the most representative of south-western Sicily, which correspond to three habitats included in the 92/43 EEC Directive (9320, 9330 and 9340, respectively) and represent the final stage of three different edaphic series. Wild olive forests probably dominated on sandy calcareous soils, holm oaks prevailed on steep calcareous and N-exposed slopes. In contrast, cork oaks mostly occurred on sandy subacid soils issuing from pedogenetic processes on palaeodunes. Moreover...
