Gypsum and Halite Deposition on Cyanobacteria and Algae in Salt‐Affected Soils.
2014
Soil surface communities are different from those of bulk soil due to the development of photo‐ synthetic communities comprising cyanobacteria, algae, and other bacteria which contribute to the formation of biological soil crusts. The structure of ecological niches forming biological crusts in saline soil environments is characterized by communities dominated by extremophiles organisms like archea, halophilic bacteria and cyanobacteria that can have a direct or indirect role in shaping soil properties. For example gypsum and halite were found by some authors as‐ sociated with the cyanobacterium Entophysalis (Braithwaite and Whitton, 1987); moreover the crystallization of gypsum and halite a…
Effect of salinity on Puccinellia distans (L.) Parl. treated with NaCl and foliarly applied glycinebetaine
2009
Turfgrasses general appearance is much affected by environmental stresses because the species used for this purpose are particularly exigent in terms of technical inputs and water need. In the Mediterranean area, sometimes irrigation is provided by using waste water which may contain high concentrations of dissolved salts which can cause salt stress injury and poor turf quality. Puccinellia distans (L.) Parl. is a halophyte cool season grass that seems to have a high salinity tolerance when cultivated in sodic soils or in NaCl-rich hydroponic cultures. We investigated the response of P. distans to salinity in a soil culture in a controlled growth environment. The effect of different concent…
Geological development of a gypsum lake formed at the beginning of the 2oth century in central Sicily, Italy: Integration of historical data with mod…
2006
A limnological investigation was carried out on the small, endorheic lake, called Lake Sfondato, located in central Sicily (Italy). All the aquatic environments in the central part of the island are rich in salt, with conductivity values above 5 mS cm−1, and are characterized by high alkalinity values and hard waters. In addition, due to intensive agriculture, many of these ecosystems have experienced a strong anthropogenic eutrophication over the last decades. In order to better understand the functioning of these peculiar environments, the morphology, hydrology, and geochemistry, as well as several selected physical and biological characteristics of Lake Sfondato, were studied in the year…
A comparative study of the mollusc communities of a Mediterranean saltwork (Marsala, Western Sicily.
2018
Saltworks are peculiar artificial ecosystems and holds great interest for basic research. In fact the cooling vat (the first pond of the evaporating series) is a good example of a relatively closed area and can be considered an excellent in the field open-air laboratory, namely a mesocosm reproducing a simplified model of the natural condition of hyperaline lagoons. The aim of the present work was to analyse the structure, composition and distribution of molluscan assemblages and to identify the faunistic relationships between the cooling vat and the neighbouring basin of Stagnone di Marsala, beside considering exchanges between saltwork, Stagnone di Marsala and sea, on soft- bottom, covere…
