Citizen science: a successful tool for monitoring biodiversity in Marine Protected Areas

2018

In the last few decades, anthopogenic activities, introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural range), and climate changes, have significantly affected Mediterranean marine biodiversity and ecosystem functioning (Coll et al., 2010). All that is also true for Marine Protected Areas (MPAs), whose major aim is biodiversity conservation. Therefore, monitoring and surveillance plans are strongly needed, and the creation of public awareness campaigns might be effective tool to plan effective management and conservation strategies in MPAs. Since intensive monitoring programs could be very expensive, citizen science, the involvement of citizens in …

ROLE OF SICILY AND CIRCUM-SICILIAN ISLANDS AS RECIPIENT AND DONOR AREA FOR ALIEN MARINE MACROPHYTES IN THE CENTRAL MEDITERRANEAN SEA

2017

The spread of alien species is an ongoing phenomenon which is widely recognized as a major threat to biodiversity at all levels. The particularly high rate of alien introductions to the Mediterranean Sea has been mainly fuelled by the opening of the Suez Canal, by shipping, aquaculture and by a rising trend in seawater temperature. As far as marine macrophytes are concerned, a total of 134 species have been listed as possible aliens in the Mediterranean Sea. Among the possible pathways of introduction, shipping is considered the dominant vector of unintentional species introduction in coastal marine systems worldwide. Traversing the Strait of Sicily, the chief passageway from south to north…

Forest ecosystems in the Monti Sicani Park (Sicily)

2022

The authors analysed the forest ecosystems in the Monti Sicani Park (Sicily). In particular, the state of the natural and non-native forests in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci, was evaluated in terms of distribution, evolution of forest dynamics and, silvicultural activities. The evolution of vegetation within two different forest plots are analysed and management strategies are proposed. The finding on Mount Cammarata of seedlings of Fagus sylvatica in the undergrowth of a conifer afforestation is noteworthy.

Tamarix, from archaeological to contemporary landscape

2018

One of the most well-known references to the presence of Tamarix species in ancient times is reported in Genesis (21:33). At that time, the tamarisks were used as decorative elements in oaths, purification, and divination. The tamarisk leaves were also used in concoctions and to ward away evil influence, and the branches to construct magic circles. The landscape surrounding the Abraham well in Beersheba is still characterized by the presence of Tamarix nilotica (Ehrenb.) Bunge. This species is particularly widespread along the banks of the sacred Jordan and Jabbok Rivers. In some old and recent paintings we can recognize habitus, habitat and, morphological features of tamarisk species such …

Fungi in archaeological areas

2018

The most renowned examples of the prehistoric use of mushrooms are represented by the stone paintings from Saharan aboriginal tribes of North Africa (ca. 9000 BC.) and the rock paintings of religious rituals in Spain (ca. 6000 years ago). The symbols, statues and paintings created by the Mayas and the Aztecs indicate the consumption of psilocybin mushrooms, especially during religious rituals, as a way to communicate with deities. Other tribes originating in Central America were also involved in magic mushrooms use for similar reasons. In northeastern Greece, western Turkey, and Bulgaria, in the regions known in antiquity as Macedonia, Anatolia, and Thrace, numerous megalithic natural rock …

BioCultural Landscapes per la rigenerazione innovativa dei territori di montagna

2017

Simplification of agricultural systems, farmland abandonment, uncontrolled urbanization, together with global scale drivers, determine fast and unpredictable phenomena of hydrogeological instability, biodiversity decline and identity loss. Men should hence promote socio-economic resilience and place identity, using biocultural landscapes as a resource. These landscapes are the outcome of the historical relationship between man and nature, resulting from complex interactions between biodiversity (at all levels, including species richness, ecosystem and biotope diversity) and cultural diversity, including material and immaterial aspects (architectural heritage, traditions, customs, local trad…

Native predators control the population of an invasive crab in no-take marine protected areas

2018

1. The resistance of an ecosystem to species invasion is considered to be related to the abundance and diversity of native species i.e. biotic resistance hypothesis). Theory predicts that the high native diversity in pristine systems can hinder the establishment and/or the spread of non‐native species through direct and indirect mechanisms (e.g. through competitive and/or predatory interactions). 2. Here we tested whether predation provides higher resistance to invasion by the Percnidae crab Percnon gibbesi (H. Milne Edwards, 1853) in protected native communities, compared with exploited ones. Specifically, this study aimed to compare: (i) the abundance and diversity of potential predator a…

Assessment of the ecological status of transitional waters in Sicily (Italy): first characterisation and classification according to a multiparametri…

2010

A 1-year cycle of observations was performed in four Sicilian transitional water systems (Oliveri-Tindari, Cape Peloro, Vendicari and Marsala) to characterise their ecological status. A panel of variables among which trophic and microbial (enzyme activities, abundance of hetetrophic bacteria and of bacterial pollution indicators) parameters, were selected. Particulate organic carbon (POC) and nitrogen (PON) and chlorophyll-. a (Chl-. a) contents defined the trophic state, while microbial hydrolysis rates and abundance gave insights on microbial community efficiency in organic matter transformation and on allochthonous inputs. To classify the trophic state of examined waters, the synthetic t…
