Mitochondrial DNA sequence data were used in MP and ML and Bayesian analyses to generate a phylogenetic hypothesis. All of the recently collected Gammarus spp. specimens belong to the G. lacustris aggregate, except scarce marginal populations of G. balcanicus and G. komareki aggregates. Although molecularly closely related, these. G. lacustris agg. populations are morphologically and ecologically equally diverse as are the numerous European Gammarus spp. Only few populations are morphologically close to the morphotype of G. lacustris. There is a more than 2,000 km wide gap between the eastern and western populations-species of G. balcanicus agg. Since Gammarus lacustris can be spread by birds, and its Asian relatives are molecularly significantly diverse, we suppose that it invaded Central Asia several times and from several sources. It most probably differentiated to diverse morphotypes after reaching Asia. The area of the cryophilic and less nomadic G. balcanicus could have been reached and conquered only by waterways. Its area was probably continuous in the past and divided by aridification during the Neogene. The strong historical aridifications probably extirpated the probably higher Gammarus diversity in Central Asia, including G. balcanicus. This opened the area and its habitats for the reiterated invasions of the particularly euryoecious G. lacustris s.l., followed by its morphological and ecological diversification.","PeriodicalId":121848,"journal":{"name":"Acta Biologica Slovenica","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121921597","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 this study its effect after the per oral administration of the ŽP strain, on the host, namely on rats of both sexes was studied. The following parameters were analyzed weight, histology of intestine, spleen and Peyer’s patches, blood biochemistry, hematology and microbicide activity of leukocytes and peritoneal macrophages. Our results showed that when administered at a dose of 5 × 108 CFU in the drinking water the ŽP strain is safe and responsible for control and maintenance of an adequate local and non-specific immune response and can also improve the performance of animals in terms of weight gain. Hence our results indicate that it is a promising probiotic.","PeriodicalId":121848,"journal":{"name":"Acta Biologica Slovenica","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126142323","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}

The present study aimed at evaluating the toxicity and antioxidant and antimicrobial activities of four cyanobacterial strains isolated from different habitats. Due to the lack of information regarding the relationship between toxicity and biological activity of the cyanobacteria in terrestrial and aquatic ecosystems of Iran, we decided to conduct a preliminary study on the cyanobacterial strains in order to identify the potentially toxic cyanobacteria strains. In this respect, biosynthesis genes related to cyanobacterial toxins, anatoxins (anaC gene), nodularins (ndaF gene) and microcystins (mcyG gene) were amplified. In addition, antioxidant, antimicrobial and biochemical properties of cyanobacterial strains have also been evaluated. The results of the molecular analysis demonstrated that only Fischerella sp. contained the microcystins (mcyG) gene. In fact, this strain encounters numerous predators in its habitat, therefore antibacterial and antioxidant metabolites found in this strain have thought to play an important role in defense mechanisms. This case is the documentation of toxicity and promotion of biological activities of a soil cyanobacterium regarding survival in competitive ecological niches.","PeriodicalId":121848,"journal":{"name":"Acta Biologica Slovenica","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116467738","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}

Health education topics are required in the extent of 15 hours in upper secondary general education schools, but in the extent of 0 to 18 hours in other secondary school programmes. The present study compared the knowledge about sexually transmitted infections of pupils of two 4-year secondary school programmes with different health education requirements. The results demonstrated that different accessibility of school health education results in distinct differences in knowledge about the existence, sources of infection, symptoms, and protection against sexually transmitted infections between pupils of different secondary school programmes. Despite the general conception of overloaded curriculums, more than two thirds of pupils of both educational programmes expressed the need of receiving more information in sexual education topics, with systematic medical exam selected as the most suitable form of sexual education, closely followed by Biology class, and school project day. The results call for the attention of educational policy makers, as they clearly emphasise the need of establishing systematic and comprehensive school health education for all pupils, not only for those enrolled in the selected secondary school programmes.","PeriodicalId":121848,"journal":{"name":"Acta Biologica Slovenica","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127827878","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}

Among the 32 strains, HGR 4, 6, 13 and 25 that were more tolerant were inoculated individually to Horse gram plants and the plants were then screened for the ability of pod formation, symbiotic efficiency and biosorption potential. Among them, maximum pod formation was observed in Horse gram upon inoculation with HGR-6 and grown at 400 µg g-1 of Al. Maximum nodulation was observed in Horse gram upon inoculation with HGR-6 and HGR-13 grown at 200 µg g-1 Al. Leghaemoglobin content was maximumon inoculation with HGR-13 at 400 µg g-1 of Al. The strain HGR-13 has shown biosorption potential in soil and as well as in root nodules even at 300 µg g-1 of Al though it was maximum at 100 µg g-1. This study demonstrated that the Horse gram plantsinoculated with Rhizobium strains HGR - 4, 6, 13 and 25, besides having nitrogen fixing ability also have the ability to grow in Al contaminated soils.

Understanding invasive organisms is important for biodiversity, science policy and water management. During monitoring sampling at Slivniško Lake (Slovenia) in 2016, the curved diatom Aulacoseira ambigua f. japonica Tuji & D.M. Williams was identified. This species originates from Japan, from where it was described more than 100 years ago. The chronology of the published distributions of A. ambigua f. japonica defines its spread from Japan to Asia, then to western Russia and South Africa, and now to central Europe. This study provides further evidence that A. ambigua f. japonica has become established in Europe (Slovenia), as supported by light microscopy and scanning electron microscopy. To the best of our knowledge, this is the first qualitative and quantitative description of A. ambigua f. japonica in Europe. It has been suggested that the shape of these algal colonies is significant for the interpretation of ecological information, and indeed, also in the present case, spiral colonies were found in this eutrophic water body.
