The mining and burning of coal are widely practiced in the tundra zone which results in the release of PAHs. The studies of PAHs content in organogenic horizon of tundra soil and southern tundra plants were performed at the control sites and at areas affected by coal industry. The soil and plants were analyzed for PAHs by HPLC. It was established that tundra soils, lichens and mosses are contaminated with polyarenes to a larger extent in the areas affected by the coal mining. The peak of PAHs concentration in the area affected by the Vorkutinskaya coal mine was observed within the distance of 0.5 km, and within 1.0 km in the area affected by the thermal power station. We propose to use diagnostic correlations of fluoranthene/ chrysene and fluoranthene/benz[b]fluoranthene in soils and mosses Pleurozium schreberi (Brid.) Mitt. to characterize the origin of polyarenes in tundra ecosystems. The similar polyarenes distribution is found in the soils and plants under the influence of coal industry. With polyarenes supply from industrial sources decreasing, their bioaccumulation level in the plants is reduced. We recommend Pleurozium schreberi to be used as a pollution indicator of tundra phytocenoses with PAHs and leaves of Betula nana L. for assessment of short-time changes of polyarene contents. The general contents rather than the surface accumulations are more suitable for the monitoring studies.","PeriodicalId":49682,"journal":{"name":"Polish Polar Research","volume":"33 S6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135544863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three rare vagrant species (eight observations) were recorded: the Chinstrap Penguin (Pygoscelis antarctica), Macaroni Penguin (Eudyptes chrysolophus) and Kelp Gull (Larus dominicanus). The Southern Giant Petrel (Macronectes giganteus; ten observations) and Pomarine Jaeger (Stercorarius pomarinus; a single observation) were visitors of the archipelago. Southern Giant Petrels and all vagrant individuals are of southern origin, the Pomarine Jaeger is a Holarctic breeding species. A single vagrant (and one uncertain case) appeared in the austral spring, and another eight – in the summer. Three cases of visitors were recorded in the austral spring, and eight in the summer. Records of vagrancy and visitors cover the dynamic period of changes in ice conditions. While most vagrants and visitors were sighted only for one day, two Macaroni Penguins stayed for several days at the archipelago. The most detailed issues in this work are those related to the study of vagrancy. I evaluate the possibilities of limited existence of vagrants and visitors into groups of endemic species as well as interspecific interactions. I also discuss the physical condition of vagrant individuals and factors contributing to their survival, ponder on the origin of vagrant individuals and visitors, their association with specific populations and","PeriodicalId":49682,"journal":{"name":"Polish Polar Research","volume":"2013 33","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This might be especially true for Arctic, where studies on the fungal diversity are still scarce. For that reason, our aim was to analyze fungal diversity in the droppings of Rangifer tarandus platyrhynchus . The samples of feces from 32 adult individuals were collected in the southern or central parts of the Wedel Jarlsberg Land (Spitsbergen, Svalbard Archipelago) and assessed for micromycetes diversity using a combination of classical and molecular identification approaches. We found 16 fungal species, out of which three were described as mesophilic, two as psychrotolerant and eleven as psychrophilic. The identified Arctic fungi belonged to eleven genera out of which representatives of Naganishia genus (formerly belonging to Cryptococcus albidus clade) were the most abundant fungal species isolated. Additionally, to our knowledge, we firstly recorded Botrytis cinerea in polar areas. We conclude that droppings of R. tarandus platyrhynchus are a source of different fungal taxa, including fungi potentially pathogenic towards humans, plants and insects.","PeriodicalId":49682,"journal":{"name":"Polish Polar Research","volume":"2000 21","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pattern matching of the profiles is supported by using graphical display enhancements, calculating spectral trend curves and generating a compound profile. Techniques routinely used in subsurface geology have been applied in correlating the profiles. Four major stratigraphic units are identified (8.1–4.9, 4.9–3.3, 3.3–1.9 and 1.9–0.1 ka b2k), resulting in an improved understanding of the climate change after the Holocene Climate Optimum. Correlatable higher-order boundaries are identified within these units. The layers between the boundaries show δ18O patterns which generally are similar in character, the differences being ascribed to lateral variations in the factors that control the isotope content of the ice. The layering forms a series of short-lived low-amplitude aperiodic oscillations on a centennial time scale. The suggestion is that these higher-order boundaries and δ18O oscillations have climatic significance. Equivalent units are tentatively identified in ice-core data from the Agassiz and Renland ice caps. Comparison with other climate proxies or stratigraphies from the Northern Hemisphere is expected to render support for the here proposed scheme. It will then serve to guide and constrain the analysis of the dynamics of the climatic fluctuations for the study period.","PeriodicalId":49682,"journal":{"name":"Polish Polar Research","volume":"40 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68952686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Across the study area species distribution often overlapped, but the domination patterns mirrored environmental conditions preferred by each species. Both species, however, were able to survive in suboptimal conditions. On a small spatial scale (in one sample) the species were separated, which may suggest an antagonistic relationship between them. The ongoing changes in the environment of Svalbard will likely affect these two species differently. The increasing intrusion of Atlantic waters will probably favor the further expansion of G. oceanicus along the Svalbard coasts. This will be due to the gradual advance of the existing population, as an influx of individuals from the Nordic seas seems unlikely. G. setosus will remain the dominant species in cold-water areas such as the inner fjords and the northeastern coast of Svalbard and may find new suitable habitats in lagoons or estuaries fed by melting glaciers. Despite predicted changes in the distribution range of both species, their future coexistence should still be possible due to the wide range of environmental tolerance and the heterogeneity of the Svalbard coastal habitats.","PeriodicalId":49682,"journal":{"name":"Polish Polar Research","volume":"19 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
