Rzadkie i ginące zbiorowiska roślin wodnych z klasy Potametea Słowińskiego Parku Narodowego
2018
Słowiński Park Narodowy, o powierzchni 32 744 ha, został utworzony w 1967 roku, a do sieci Światowych Rezerwatów Biosfery włączony w 1977 roku. Ponad połowę obszaru parku zajmują ekosystemy wodne, w tym pobrzeże Bałtyku, jeziora Łebsko, Gardno, Dołgie Wielkie i Dołgie Małe oraz w mniejszym stopniu rzeki: Łeba, Łupawa i Pustynka. W trakcie badań prowadzonych w latach 2013–2014 stwierdzono stanowiska czterech rzadkich i ginących zbiorowisk roślin wodnych z klasy Potametea, nienotowanych dotąd na obszarze Słowińskiego PN. Są to zespoły: rdestnicy trawiastej Potametum graminei, rdestnicy alpejskiej Potametum alpini, rogatka krótkoszyjkowego Ceratophylletum submersi ze związku Potamion oraz zesp…
COSMOPOLITAN HABITAT WORKSHOP
2021
The Cosmopolitan Habitat workshop invites international PhD candidates, students, young scientists, academics, and urban planning and design professionals to discuss and reflect on the spatial dimension of migration, the different human cultures that increasingly characterize European cities, and new living spaces in the project area, the historic centre of Palermo. The students, together with young urban planning and design scientists, are asked to discover potentialities for Cosmopolitan Habitat in Palermo and design new future scenarios. The paper reports the outcomes of the workshop.
Crustacea Decapoda from Ustica (Southern Tyrrhenian Sea): species distribution and sampling approach.
2011
The decapod crustacean fauna of Ustica Island (Sicily, southern Tyrrhenian Sea) has been investigated in summer 2002 with the aid of many different sampling methods: suction device, pushnet, skid trawl, trammel net, traps, underwater observation, interviews. All the substrata occurring around the island from 0 to about -30 m were surveyed: midlittoral rock, infralittoral rock, pebbles, seagrass (Posidonia oceanica) bed, sand, detritic bottom, submerged cave. Fiftyseven species were collected in the investigated localities. Abundance and frequency of all species in the samples and in each surveyed biotope are given. The performance of each sampling method has been evaluated, in terms of numb…
Spatial analysis of lanner falcon habitat preferences: Implications for agro-ecosystems management at landscape scale and raptor conservation
2014
Abstract Sicily hosts the largest European population of the endangered lanner falcon, a poorly known species which needs conservation planning based on habitat preferences. A distribution model on 10 × 10 km cells of Sicily was described using Generalized Linear Models and variation partitioning methods. This modelling approach extracted explanatory factors, pure and joint effects of greatest influence from subsets of variables controlled for multi-collinearity and spatial autocorrelation. Analytical cartography used the environmental favourability function to assess habitat preferences, and the insecurity index estimated the degree to which lanner falcon occupancy is represented in the Na…
Assessment of the Sabellaria alveolata reefs’ structural features along the Southern coast of Sicily (Strait of Sicily, Mediterranean Sea)
2022
The honeycomb worm Sabellaria alveolata is a gregarious tube-dwelling polychaete that builds remarkable biogenic reefs in marine coastal waters. Sabellaria alveolata reefs are considered valuable marine habitats requiring protection measures for their conservation, as they play a key role in the functioning of coastal ecosystems. Sabellarid reefs are extensively developed along the Atlantic coasts of Europe and reported for the Mediterranean Sea and the Italian coasts, where large reefs have been recorded in several localities. Fragmentary information is available on their health status, Sabellaria reefs thus being listed as “Data Deficient” in the Red List of Marine Habitats. To fill this …
Urban Services to Ecosystems: An Introduction
2021
Green infrastructure is a structural system of naturally developed human societies, capable of preserving and ensuring as much space as possible to the local biodiversity. For this reason, green infrastructure shall be planned and designed so that the urban built environment is in harmony with the surrounding biotic communities. The challenge is to sustain nature-based solutions in order to improve citizens’ awareness towards natural and semi-natural ecosystems while providing our society with a more liveable, healthier, safer and fairer environment. This book puts an emphasis on the services the city can offer to nature, thanks to a multidisciplinary approach involving scientists and pract…
The Role of Aquatic Refuge Habitats for Fish, and Threats in the Context of Climate Change and Human Impact, during Seasonal Hydrological Drought in …
2021
In spite of the obvious climate changes effects on the Carpathian Basin hydrographic nets fish fauna, studies on their potential refuge habitats in drought periods are scarce. Multiannual (2016–2021) research of fish in some streams located in the Saxon Villages area during hydrological drought periods identified, mapped, and revealed the refuge aquatic habitats presence, management needs, and importance for fish diversity and abundance for small rivers. The impact of increasing global temperature and other human activities induced hydrologic net and habitats alteration, decreased the refuge habitats needed by freshwater fish, diminished the fish abundance, and influenced the spatial and te…
Towards the urbanisation of the Med sea: MSP challenges and opportunities for floating cities between utopia and reality
2023
Anthropogenic climate change effects push us to reimagine human life on the planet confronting extreme living conditions. Droughts, risk of submersion and flooding, saline intrusion, and land scarcity lead to more inhospitable life conditions on land. These demanding risks have led governments to envisage the displacement from the coasts of some cities at significant risk or to think of new settlements for human life, such as floating cities. Floating offshore settlements, reminiscent of the XXth-century architectural utopias, are gaining more and more popularity in contemporary debate and are, in fact, emerging realities in other parts of the globe due to advanced technology. Floating sett…
