Vegetation series as a marker of interactions between rural settlements and landscape: new insights from the archaeological record in Western Sicily
2020
[EN] Plant communities are complex and dynamic elements of the landscape, intertwined with both natural factors and human activities. Vegetation series reflect the environmental characteristics of the landscape, but also the anthropic impact, one of the exogenous forces that most profoundly affects the landscape formation process. This paper aims to investigate the interactions between long-term human settlement catchment areas and vegetation series. The case study area of the Sicani Mountains (Central-Western Sicily) proved to be an ideal place to perform GIS-based spatial analysis in order to compare a data set of rural archaeological sites and land units created through the mapping of ve…
A multifaceted field sampling approach for the management of extremely narrow endemic vascular plant species
2022
Extremely narrow endemic plant species (ENEs) are generally connected with micro- refugia characterized by particular environmental conditions. In-depth knowledge of the ecological requirements of ENEs is fundamental to plan appropriate conservation measures. Using cross-cutting technology, this paper gives a multifaceted approach to collect on-site data on the ecology of ENEs, defines the protocols for a correct sampling design and describes the type of equipment, the time and expenditure needed. Our sampling approach is based on two orthogonal transects, long enough to extrapolate the whole ecological gradient across the area of occupancy of the target species. Microclimatic data are reco…
Partially disarticulated new Miocene burrower bug (Hemiptera: Heteroptera: Cydnidae) from Cerová (Slovakia) documents occasional preservation of terr…
2015
The state of preservation of the bug Sehirus carpathiensis J.A. Lis, Vršanský & Schlögl, sp. n. (Hemiptera: Heteroptera: Cydnidae) from the Lakšárska Nová Ves Formation at Cerová (Slovakia) supports extremely rapid sinking and burial in upper bathyal Early Miocene sediments. The specimen originated from land at most a few kilometers away, but transport via a river can be excluded as the head and wings are still attached. Its most likely source based on fossil flora and the habitat of several living representatives of the genus is a riparian habitat in an adjacent area of land. Phylogenetically the new species is closely related to both Oligocene and living representatives of the genus, thus…
Multi‐specific small‐scale fisheries rely on few, locally essential, species: Evidence from a multi‐area study in the Mediterranean
2022
Achieving sound management of small-scale fisheries (SSFs) is globally recognized a key priority for sustaining livelihoods, local economies, social wealth and cultural heritage in coastal areas. The paucity of information on SSFs often prevents the proper assessment of different socio-ecological aspects, potentially leading to draw inappropriate conclusions and hampering the development and adoption of effective policies to foster SSF sustainability. To respond to the growing global call to assess these fisheries, we carried out a multi-disciplinary and data-rich assessment of SSFs at 11 areas in 6 Mediterranean EU countries, combining the analysis of 1292 SSF fishing operations and 149 se…
Effects of Social Hierarchy Establishment on Stress Response and Cell Phagocytosis in Gilt-Head Sea Bream (Sparus aurata)
2022
Social stress can affect the ability of fish to respond to various stressors, such as pathogens or environmental variations. In this paper, the effects of social stress on gilt-head bream (Sparus aurata) were investigated. To study the effects of physiological stress, we evaluated biochemical and cellular parameters, such as cortisol, glucose, lactate, osmolarity, and phagocytosis, 24 h after the establishment of social hierarchy in a group of three fish. Social hierarchy was determined and characterized by behavioral observation (aggressive acts and feeding order) of the specimens (dominant: “α”; subordinate: “β” and “γ”). After the esta…
Health Promotion Interventions in Sports Clubs: Can We Talk About a Setting-Based Approach? A Systematic Mapping Review
2019
Many researchers and authorities have recognized the important role that sports clubs can play in public health. In spite of attempts to create a theoretical framework in the early 2000s, a thorough understanding of sports clubs as a setting for health promotion (HP) is lacking. Despite calls for more effective, sustainable, and theoretically grounded interventions, previous literature reviews have identified no controlled studies assessing HP interventions in sports clubs. This systematic mapping review details how the settings-based approach is applied through HP interventions in sports clubs and highlights facilitators and barriers for sports clubs to become health-promoting settings. In…
Análisis conjunto y espacios naturales: una aplicación al Paraje Natural del Desert de les Palmes
2007
We use stated preference methods to analyze consumer preferences on the attributes of protected natural areas and to estimate the willingness to pay for reducing the risk of fires in the site. For the first goal, conjoint analysis is used. Three attributes are considered: biodiversity, dimension of the natural area and the economic contribution that would have to be made for its maintenance and preservation. The willingness to pay for reducing the risk of fires has been estimated using choice experiment. The data have been gathered from a mail survey conducted among people living near the Desert de les Palmes Park, a protected area located in the Valencian Community (Spain). En el trabajo s…
Badania społeczne w branży OZE w Polsce
2017
Artykuł stanowi przegląd badań społecznych w branży odnawialnych źródeł energii w Polsce. Na podstawie kwerendy danych zastanych wyróżnionych zostało pięć obszarów, w których są stosowane badania społeczne odnoszące się do energetyki odnawialnej: badania opinii publicznej, badania informacyjno-promocyjne, badania rynkowe i marketingowe, badania ewaluacyjne oraz badania diagnostyczne i prognostyczne. W każdym z tych obszarów realizowane badania służą innym celom i potrzebom zlecających, występuje odmienna specyfika doboru metod i technik badawczych, a także forma i zakres przedstawionych wniosków, raportu końcowego. Niezależnie jednak od charakteru badań można stwierdzić, że następuje rozwój…
Applying the RUSLE and ISUM in the Tierra de Barros Vineyards (Extremadura, Spain) to Estimate Soil Mobilisation Rates
2020
Spain is one of the largest wine producers in the world, with Extremadura (south-west Spain) being its second-largest producing region after Castilla La Mancha. Within Extremadura, the most traditional and productive viticulture region is the Tierra de Barros, which boasts an annual production of 3×
The Utility of Ground Bryophytes in the Assessment of Soil Condition in Heavy Metal-Polluted Grasslands
2022
Bryophytes are commonly used in biomonitoring heavy metal pollution, whereas the bioindicative value of bryophyte communities is a less known issue. The aim of the present study is to recognize the utility of the bryophyte community’s structure in the assessment of soil condition in heavy metal-polluted, dry grasslands. The study plots are examined with respect to bryophytes; vascular plants; concentrations of Zn, Pb, Cd, and As in the soil; total nitrogen and organic carbon content in the soil; and soil pH. The results show that both bryophyte species richness and composition greatly depend on soil chemical characteristics, including heavy-metal pollution levels and soil pH. Three groups o…
