In this study, we focused on the characterization of Gram-negative bacterial isolates obtained from Mauremys rivulata (Western Caspian turtle), Natrix natrix (Grass snake), Natrix tessellata (Dice snake) and Pelophylax bedriagae (Levantine frog) using cultural methods and determine some virulence factors (antibiotic resistance, VanA and TetM resistant genes, biofilm, siderophore and some enzymatic activities etc.). Multiple antibiotic resistance (MAR) and virulence index (VI) of each strain were also calculated. A total of 85 Gram-negative isolates exhibited varying levels of antibiotic resistance and the ability to produce one or more extracellular enzymes such as amylase, lecithinase, protease, lipase, hemolysis, siderophore, amino acid decarboxylase and DNase. Although the TetM has been identified in all 7 isolates, none of the isolates have shown the presence of the VanA gene. According to MAR and VI results, most of the isolates were found to be in the high threat group and these indexes were correlated with antibiotic resistance. The study data revealed that chemicals used in industry and agriculture both trigger environmental pollution and pose risk factors for wildlife.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"31 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed the data using the statistical parsimony, maximum likelihood, and NeighborNet approaches. According to our results, the majority of species may be subdivided into three groups roughly corresponding to the taxonomic sections Pimpinellifoliae, Rosa (former Cinnamomeae) and Synstylae + Chinenses + Gallicanae + Caninae. We assess their relationships as broadly paraphyletic, since the first group appears to be ancestral to the second and the third. The fourth group distanced from these three by many mutational steps consists of R. persica (subgenus Hulthemia) sequences. We argue that R. persica together with the North American R. minutifolia and R. stellata (section Minutifoliae) probably represent the only remnants of an ancient group of roses widely distributed in the Northern Hemisphere in the Oligocene. Two major lineages of the section Caninae arose independently from different ancestors belonging to Synstylae.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"72 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140575972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seasonal maps of the mean annual Chl-a estimations were created for the Barents Sea. Significant seasonal and temporal variations of Chl-a were found in different water masses. The surface Chl-a content reached a maximum in the spring (46% of the annual estimation). In the summer, it tended to decrease accounting for 28% of the total annual value, while in the autumn and winter, Chl-a was found to be 21 and 5% of the total annual stock, respectively. Atlantic Water and Arctic Water had the highest contribution to the total annual Chl-a biomass. In Arctic Water, peaks of the Chl-a concentrations were registered in spring and these decreased in summer and autumn. The summer season was the most productive period in Atlantic Water. The Chl-a dynamics and distribution in relation to climatic factors were investigated. Application of generalized linear and non-linear models to predict Chl-a variations showed the great significance of the indices associated with the global atmospheric circulation, mean annual temperature, and salinity anomalies, as well as the extent of ice in the Barents Sea.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"256 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140575973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
