Climate change in Southeastern Europe (SEE) and forecasts for the period until 2070 have a huge impact on the present and future planning in forestry and watershed management, due to the observed trends: the increment of mean annual air temperature from 2,5–5,0 °C until the end of the XXI century; redistribution of annual precipitation, with much more precipitation in the spring-summer period, during short, intensive rain events; a decrease of annual precipitation and soil moisture of 10–20 %, with extreme consequences: dieback and disappearance of forests in huge areas of hilly-mountainous regions. Degradation and loss of forests leads to spread and intensification of soil erosion, with frequent torrential floods, mudflows, landslides, and avalanches. Stable forest ecosystems are pillars of sustainable development, repopulation and could provide means and resources to battle and overcome poverty in moun-tainous regions of southeast Europe.","PeriodicalId":414830,"journal":{"name":"Contributions, Section of Natural, Mathematical and Biotechnical Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129758497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intracellular iron varies within normality ranges, and depletion or overload of brings serious consequences. As such, iron can also be deleterious when appearing as an environmental toxicant. The aim of this study was to estimate semi-quantitatively the liver iron content in female Ohrid trout, from the Lake Ohrid, during the breeding cycle. Seasonal variations in hepatocytic iron were observed. The maximum content occurred at post-spawning, which was significantly higher than loads detected at pre- and early-vitellogenesis. Positive correlations existed between iron amounts and stages of ovary maturation. By the contrary, there were no correlations between iron contents and plasma oestradiol levels. The new uncovered \"iron-breeding associa-tion\" strongly endorses that normal seasonal variations in hepatocytic iron content should be taken into consideration in field studies investigating and monitoring the metal burden and toxicological effects of metals on wild fish.","PeriodicalId":414830,"journal":{"name":"Contributions, Section of Natural, Mathematical and Biotechnical Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126720490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total 31 water samples were collected, from which 8 samples from the Crna River and 4 samples from four main tributaries of Crna River in the Pelagonia Valley (Blato, Prilepska Reka, Dragor and Jelaška Reka). Also, surface water samples were collected from 3 locations in the Tikveš Lake, 8 locations from the Majdanska River and river of Blašnica before its inflow into the Tikveš Lake and from 7 locations of the lower course of the Crna River after the dam of Tikveš Lake until its inflow into the river of Vardar. Determination of the concen-tration of the investigated elements was performed by using atomic emission spectrometry with inductively coupled plasma (ICP-AES). All data obtained for the analyzed samples were statistically processed using software Stat Soft 11.0 where the descriptive statistical analysis of the value for the concentration of the elements was performed. The maps of spatial distribution of the concentration for each element and a histograms for the representation of elements with mean values of the concentrations by regions, were also prepared. The obtained results show that the concentration of investigated element are mainly followed the lithology of the region. However, higher concentrations of arsenic were found in the water samples from the river of Blašnica which is a result of anthropogenic influence from the abounded Allchar mine on the Kožuf Mountain. Also, the increased concentrations of nickel were found in the samples from the lower couse of the Crna River after the dam of Tikveš Lake due to the anthropogenic influence from the ferronickel smelter plant Feni Industry, which can influence the quality parameters of surface waters.","PeriodicalId":414830,"journal":{"name":"Contributions, Section of Natural, Mathematical and Biotechnical Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131388047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
