“…This species, being an iron concentrator, does not show symptoms of poisoning in the form of chlorosis. Earlier, we showed that in the forecourt areas of the polar cities, middle-weakened specimens of Larix sibirica predominated and retained the ability to natural regeneration (Saltan and Sviatkovskaya 2021). It should be noted that the soils in the region belong to the Al-Fe humus podzolic type with naturally high iron content (Pereverzev 2004).…”

For the first time, a study of the ecophysiological features of the introduced Larix sibirica (middle-aged plantations old 40-50 years) was carried out at a tree nursery and railway stations in four cities in the Kola Subarctic. Content of photosynthetic pigments (per fresh weight) ranged 1185 – 1894 μg·g-1 (chlorophyll a), 377 – 666 μg·g-1 (chlorophyll b), and 256 – 387 μg·g-1 (carotenoids). Exception was found for the specimens from Murmansk (significantly higher) and Olenegorsk (significantly lower values). High content of Fe was found in needles (1865 – 4278 mg·kg-1), however, it did not lead to any damage or abnormalities in the development of Larix sibirica. A close positive correlation was shown between the Fe and Mn contents (r = 0.91). Ni and Cu content in needles increased in all cities from 3 to 8 times in comparison with the background, Pb content increased only in the cities of Apatity and Olenegorsk (2–4 times). The amount of Cd and Zn was found within the optimal range. This study revealed the negative effects of the main pollutants (Ni, Cu, and Pb from the mining industry) on chlorophyll a (r = -0.81) and carotenoids (r = -0.70).

“…The environmental consequences of urbanization in the Arctic are overlooked so far; however, changes in Arctic vegetation and soils driven by urbanization can be irreversible and dramatic [ 7 , 8 ]. Industrial and mining activities result in severe environmental pollution, which affects the vegetation state and diversity [ 9 ] and soil quality [ 10 , 11 ]. At the same time, the urbanization effect on soils is not limited to pollution.…”

Urbanization in the Arctic results in considerable and still poorly known environmental consequences. The effect of urbanization on soil microbiome—an ecosystem component highly sensitive to anthropogenic disturbance—remains overlooked for the Arctic region. The research compared chemical and microbial properties of the natural Podzol soils and urban soils of Murmansk—the largest Arctic city. Particular attention was given to the profile distribution, which is almost completely ignored by most microbial studies. Soil microbiome was investigated by the quantitative indicators based on fluorescence microscopy (microbial biomass) and PCR real-time methods (amount of rRNA genes copies of archaea, bacteria, and fungi). The principal changes in urban soils’ properties compared to the natural references included a shift in pH and an increase in C and nutrients’ contents, especially remarkable for the subsoil. The numbers of rRNA genes copies of archaea, bacteria, and fungi in urban topsoils (106–1010, 109–1010, and 107–109, respectively) were lower than in Podzol; however, the opposite pattern was shown for the subsoil. Similarly, the total microbial biomass in urban topsoils (0.55–0.75 mg g−1) was lower compared to the 1.02 mg g−1 in Podzols, while urban subsoil microbial biomass was 2–2.5 times higher than in the natural conditions. Both for urban and natural soils and throughout the profiles, fungi were dominated by mycelium forms; however, the ratios of mycelium–spores were lower, and the amount of thin mycelium was higher in urban soils than in natural Podzols. Urbanization in the Arctic altered soil morphological and chemical properties and created a new niche for microbial development in urban subsoils; its contribution to biodiversity and nutrient cycling promises to become increasingly important under projected climate change.
