Hypersaline environments are among the most vulnerable coastal ecosystems and are extremely noteworthy for a variety of ecological reasons. Comprehensive assessment of metal(oid) contamination in ...hypersaline sediments from Sečovlje (Northern Adriatic, Slovenia) was addressed by introducing the detrital and diagenetic mineralogy and geochemical properties within the solid sediment material. Close associations between Fe/Mn oxides and oxyhydroxides with As, Cr, Ni, Pb and Zn, and between organic matter with Cu, Pb and Zn were confirmed using X-ray powder diffraction, SEM-EDS and ICP emission spectrometry analysis. Possible incorporation or adsorption on the crystal lattices of clay minerals (As, Cr, Pb, Sn and Zn), halite (As) and aragonite/calcite (Cd, Cu, Pb, Sr and Zn) were also detected. All presented correlations were highlighted by various statistical analyses. The enrichment factor (EF) values showed a low degree of anthropogenic burden for As, Bi, Hg and Zn, while Cd, Cr, Cu, Ni, Pb, Sn and Sr originated from the geological background. These results emphasise that a detailed mineralogical and geochemical characterisation of solid (especially detrital and diagenetic) sediment particles is crucial in further understanding the metal(oid) translocation within the hypersaline ecosystems.
Years ago, the Common Tern S
h
was known to nest in Slovenia along larger watercourses. Today it only breeds locally in artificially built nesting areas. On the seashore, its nesting was confirmed ...for the first time in 1983, when 9 pairs bred in the Sečovlje Saltpans. In the same year, we started mapping the breeders in the Sečovlje Saltpans, which has continued till this very day. Since 2010, we have been systematically collecting data on the number of fledged birds. In 1991, the number of breeding pairs increased, which coincides with the increase in other parts of the Mediterranean. Since 1991, the size of the breeding population has been quite stable, ranging from 30 to 70 pairs. The Common Tern’s breeding success in the Sečovlje Saltpans is poor, mainly due to precipitation (40% of all unsuccessful nests) and predation (35%). Long, dry periods without rainfall have a positive effect on the hatching and fledging success. Appropriate water management, artificial islands and access to nesting sites control can prevent the disturbance caused by visitors and, in part, predators such as foxes and martens. At the Sečovlje Saltpans, the Common Tern’s survival depends entirely on the active management. The expected climate change, with increasing sea level rise and consequently more frequent flooding of low-lying areas, further aggravates its existence and survival in the Sečovlje Saltpans.
The Sečovlje saltern is one of the few remaining solar salterns for traditional, seasonal salt production. The bottom of the crystallizer ponds is covered with a microbial mat, known as the ‘petola', ...that has continuously been cultivated from medieval times. Outside the salt production season, the petola is fertilized with anoxic marine mud and covered with saline water; during the season, it is covered by brine. Here, we have applied culture-independent techniques and microelectrode-based activity measurements to study the bacterial communities in three different layers of the petola during the peak of the harvesting season. For reference, we used nonactive petola that had been abandoned for several years. The upper 2 mm of the petola were dominated by the cyanobacterial species Coleofasciculus chthonoplastes and the Phormidium/Lyngbya group, and Gammaproteobacteria (Acinetobacter sp.), while the third anoxic layer was dominated by as yet uncultured phyla. The nonactive petola showed a higher biodiversity. Oxygen and sulfide concentrations differed between the mats studied, in terms of the depth of oxygen penetration and diel changes. This study provides the first molecular insight into the microbiology of the petola, and it represents an important contribution towards understanding the geomicrobiological cycles of the traditional Sečovlje saltern.
In our research the concentrations of major and minor elements were determined in natural sea salts from the Se~ovlje salina (Piran salts, Slovenia) and compared to those of selected samples of ...commercially available unrefined salts with different geographical origins (Croatia, Austria, Italy, Portugal, India, and Pakistan). In the case of major element contents such as sodium (Na), iron (Fe), aluminum (Al), manganese (Mn), and titanium (Ti) many similarities were observed among the analysed salt samples. On the other hand, Piran salts are characterized by lower silicon (Si) values. Among the salts from the Sečovlje salina, the salt with the trade name Piran salt has a higher Mg content while Flower of salt has a lower concentration of calcium (Ca). In Slovenian samples the majority of trace element values were lower than 0.5 µg g-1, which was comparable to the results from commercially available unrefined salts. The salt composition differences observed indicate area-specific signatures related to geographic origin and diverse salt production processes. The quality of the studied salt samples is in accordance with standards established by the Codex Alimentarius Commission and the Piran salts are also suitable regarding issues of national food control.
The monograph presents different names of Piran Bay (Slo. Piranski zaliv) over time. Despite the leading onomastic topic, the publication is designed as a regional-geographic review of Piran Bay and ...its hinterland, where all the main physical- and socio-geographical characteristics are presented. This book describes the basic hydro-geographic characteristics of Piran Bay as a part of Gulf of Trieste and the Adriatic Sea. The monograph talks about the historical development, salt making in Sečovlje salt pans and the circumstances that led to the now more than two decades-long border dispute between Slovenia and Croatia. A significant chapter is dedicated to the presentation of the different naming of the Bay of Piran through time. According to the chronological order, 104 different cartographic sources present the name changes of the Piran Bay through time and when a certain specific geographic name appeared. Based on media analysis, one of the chapters describes the relation between the names Savudrijska vala or Savudrijski zaljev (Savudrija Bay) and Piranski zaliv or Piranski zaljev (Piran Bay).
A negative attitude toward wetlands along with an ignorance regarding them and a lack of awareness about their value have often led to their transformation by humans. Their massive degradation and ...consequently their disappearance were the main reasons for the establishment of the Ramsar Convention, the first intergovernmental agreement on the preservation and sustainable use of wetlands. There are three wetlands in Slovenia on the Ramsar List of Wetlands of International Importance: the Secovlje salt pans, Skocjan Caves, and Cerknica Lake and its surroundings. Using a questionnaire survey, we tried to ascertain the level of public awareness about wetlands and attitudes toward their conservation. On the basis of the results acquired, we discovered that public awareness about wetlands conservation depends primarily on the location of residence and the social structure of the population. A negative opinion on the advantages of life in the protected areas within which the Ramsar localities are located was revealed, the result of a lack of information and insufficient knowledge of the environmental and economic functions of wetlands. Effective programs of education and involvement of the population in activities in protected areas must be implemented in the future. The comprehensive education of local people and interdisciplinary cooperation are the key points for changing human perception on the importance of protecting these vulnerable ecosystems.

Pri poplavah leta 1966, ki so nastale zaradi visoke plime ob slovenski obali, je nastala posebna velika škoda ...v Piranskih solinah, kjer je voda porušila del zapornega nasipa in vdrla na soline. Cenijo, da znaša škoda od 180 do 200 milijonov starih dinarjev. Kolektiv je še bolj prizadet zaradi tega, ker je bil letošnji pridelek soli zaradi poletnega deževja slabši kot kdajkoli prej. Mnenja so, da poplavljenih solnih polj in drugih naprav ne bodo mogli popraviti pred pomladjo.
The last floods in 1966, caused by high tides along the Slovenian coast, and as a consequence, significant damage to Piran's Sečovlje Salterns. High water demolished part of the embankment and usurped the Salterns. The damage which ensued was estimated up from 180 to 200 million in the currency used at this time - the dinar -. The effects of these floods were even more devastating because of the earlier rainy season, which had a huge effect upon the production of salt, and was the lowest crop of salt ever. At that time they knew the reparation of the flooded salt evaporation ponds and other facilities would not be repaired before the spring.- Information:- High tides along the Slovenian coast, which caused flooding and also enormous damage at Sečovlje Salterns as a consequence of these high tides. Water demolished part of the embankment.- Original language summary:
