“…Bubnova et al (2014) detected three obligate marine species in the sediments (Acremonium fuci, Paradendryphiella arenaria and P. salina), all the rest were classified as land-origin species. The fungal composition was represented mainly by the cosmopolitan species (Penicillium spp.)…”

The major part of the north polar region is intensely rising by postglacial crustal movement. This process gives rise to the separation of different basins from seas and oceans, which affects a combination of freshwater and marine organisms. Gradually losing contact with the seas, many near-shore lakes of the Arctic are mostly desalted and form bogs. Fungi as decomposers play an important role in all ecosystems. However, the diversity and role of fungi in Arctic aquatic ecosystems is largely unknown. It is also not clear how the taxonomic structure of the fungal community is affected by the process of gradual desalinization and waterlogging. We investigated the diversity of filamentous culturable fungi in different parts of the brackish Kislo-Sladkoe Lake (White Sea, Russia). Annually, 42 samples of the bottom and coastal soils have been collected at the lake from which fungi were recovered on standard and selective media. Based on morphological and molecular markers, a total of 127 taxa have been identified. The fungal community appeared to be influenced by its sea origin and comprised both marine (Paradendryphiella salina, Acremonium spp.) and terrestrial soil species of Penicillium, Talaromyces, Mucor, Umbelopsis, Cladosporium, Cadophora, Sistotrema, Helotiales, Pleosporales, sphagnum moss destructors (Oidiodendron spp.) and insect-associated species of Tolypocladium. The results indicate that the composition of the fungal community in the rising polar White Sea region reflects the dynamics of global changes in physical-chemical parameters and animal and plant associations because of separation from the sea.

“…Climatic factors globally affect the distribution of biota, including one of the most prominent inhabitants of the oligotrophic peats -an arctic mosquito (Aedes spp., Culex spp.). During warm season, these species reproduce in bulk, and along with the plant material, can act as a food source for fungi (Bubnova et al, 2014). Our research attempts to compare fungal diversity of the two distinct following types of peatlands -the White Sea coastal peatlands (White Sea Biological Station, WSBS, northern, 66°34ʹ N, 33°08ʹ E) and the Smolensk region peatlands (National Park «Smolenskoye Poozerie», SP, central, 55°53ʹ N, 31°40ʹ E) ( Fig.).…”

The current study addresses the fungal diversity of the peatlands that vary geographically and geologically, in the central and northern parts of Russia. The central (Smolenskaya area, National Park «Smolenskoye Poozerie») and northern (White Sea Biological Station area) peatlands have a different geological history, the former have a glacial origin, while the latter are of marine origin. Our aim was to investigate the fungal biota of these zones full of Sphagnum moss, and possibly reveal the species that are pertinent to these particular habitats.In both investigated areas, we found an overall poor species diversity with a high fraction of sterile mycelia. Many penicillia species were dominating in all peat samples -P. thomii, P. spinulosum, P. glabrum, P. funiculosum, P. aurantiogriseum (together with Geotrichum candidum), many of them are known to degrade Sphagnum. We were particularly interested in the dynamics of the species from the genus Oidiodendron that have been shown to be involved in primary Sphagnum degradation. The northern area contained a larger species diversity of Oidiodendron, as compared to the central zone. Interestingly, insect-associated species of the genus Tolypocladium and Beauveria, along with the psychrotolerant species of Geomyces and Tolypocladium were recovered only from the northern peatlands. Aspergillus spp. were found in peatlands of the central zone only. We link this result to the climatic features of the area, but also different invertebrate contents that may be utilized by fungi. We detected a tendency of an increasing diversity of Oidiodendron species, psychrotolerant and entomopathogenic fungal species as well as a proportion of sterile forms in the northern area.
