Abstract

W pracy przedstawiono wyniki badań dotyczące zawartości wybranych metali ciężkich (As, Mn, Ni, Sn, Ti) w glebie i roślinach na obszarze węzła kolejowego Iława Główna. Próby gleby i roślin pobierano w czterech częściach węzła, a mianowicie na rampie załadowczej, torowisku głównym, myjni i bocznicy kolejowej. Na całym obszarze węzła kolejowego stwierdzono podwyższone stężenia metali ciężkich w porównaniu z terenem kontrolnym. Najwyższe stężenia stwierdzano na torowisku głównym i bocznicy kolejowej. Stężenie arsenu, manganu i niklu w roślinach występujących na tym obszarze przekracza poziom toksyczny. Najwyższe zanieczyszczenie gleby i roślin stwierdzane na torowisku wskazuje na występowanie procesów emisji metali spowodowanych ścieraniem kół i szyn. Porównanie z danymi literaturowymi wskazuje, że stężenie badanych metali w glebie jest większe niż w glebach centów miast i wzdłuż drogowych szlaków komunikacyjnych, co dowodzi, że linie kolejowe stanowią istotne liniowe źródło zanieczyszczenia gleby

Abstract

Baltic Sea is one of the World's most oxygen-depletes seas, so the region requires urgent mitigation measures to significantly reduce nitrogen and phosphorus inputs from land through rivers, which cannot be achieved without large-scale restoration of wetland buffer zones. The manuscript summarises the findings of the discrete choice experiment aimed at assessment of the preferences of Danish, German, and Polish citizens towards ecosystem services of lowland small rivers of the Baltic Sea basin. Our results suggest that respondents in all the studied countries are willing to pay substantial amounts to improve water quality in rivers and the Baltic Sea, as well as to restore naturally meandering rivers and natural riparian vegetation. Wild marshes and Wetland agriculture were equally valued as the most desirable options. Respondents systematically cared about the appearance of small rivers in their neighbourhood. We conclude that re-meandering, re-wetting of floodplains, and restoration of wild marshes (i.e. natural wetland vegetation) or development of wetland agriculture could gain a lot of public support in Europe.

Abstract

We studied an invasion of Poa annua on King George Island (Maritime Antarctic). The remoteness of this location, its geographic isolation, and its limited human traffic provided an opportunity to trace the history of an invasion of the species. Poa annua was recorded for the first time at H. Arctowski Polish Antarctic Station in the austral summer of 1985/6. In 2008/9, the species was observed in a new locality at the Ecology Glacier Forefield (1.5 km from 'Arctowski'). We used AFLP to analyze the genetic differences among three populations of P. annua: the two mentioned above ( Station and Forefield) and the putative origin of the introduction, Warsaw (Poland). There was 38% genetic variance among the populations. Pairwise ФPT was 0.498 between the Forefield and Warsaw populations and 0.283 between Warsaw and Station. There were 15 unique bands in the Warsaw population (frequency from 6% to 100%) and one in the Station/Forefield populations (which appears in all analyzed individuals from both populations). The Δ( K) parameter indicated two groups of samples: Warsaw/Station and Forefield. As indicated by Fu's Fs statistics and an analysis of mismatch distribution, the Forefield population underwent a bottleneck and/or founder effect. The Forefield population was likely introduced by secondary dispersal from the Station population. [ABSTRACT FROM AUTHOR]

42. Diaspores of the Introduced Species Poa annuaL. in Soil Samples from King George Island (South Shetlands, Antarctica)

Abstract

AbstractThe soil seed bank and seed germination capacity of Poa annuain the vicinity of the Polish Antarctic Station (South Shetlands, Antarctica) were investigated. It was documented that annual bluegrass can reproduce sexually and produce a functional seed bank of close to 5000 seeds/m2under maritime Antarctic conditions. Comparison of germination between Poa annuaand two native plant species revealed that Poa annuaseeds can germinate as fast or even faster than native species, and are more vigorous. Our studies show that in the Antarctic Poa annuacan successfully reproduce sexually and produce fully developed, viable caryopses that are able to survive the maritime Antarctic winter, not only in a soil bank, but also directly in the previous year’s inflorescences.
