Cryoconite is a mixture of mineral and organic material covering glacial ice, playing important roles in biogeochemical cycles lowering the albedo glacier surface. Understanding differences structure cryoconite across globe can be recognizing past future changes supraglacial environments ice-organisms-minerals interactions. Despite worldwide distribution over century studies, basic characteristics cryoconite, including its forms geochemistry, remain poorly studied. The major purpose our...
Low nitrogen availability in the high Arctic represents a major constraint for plant growth, which limits tundra capacity carbon retention and determines vegetation types. The limited terrestrial (N) pool is augmented significantly by nesting seabirds, such as planktivorous Little Auk (Alle alle). Therefore, N delivered these birds may influence cycling locally budget more globally. Moreover, should experience substantial negative environmental pressure associated with climate change, this...
Despite recent great interest in glacier ecosystems the continental Antarctic, little is known about their maritime counterparts. Our study presents descriptive data on cryoconite sediments and holes Ecology Glacier (King George Island) to accomplish three main objectives: (a) identify eukaryotic (algae, invertebrates) prokaryotic (cyanobacteria) components of microbial communities; (b) provide a "baseline" community composition, organic matter artificial contamination; (c) key abiotic...
Cryoconite holes (water reservoirs) significantly contribute to biodiversity and biogeochemical processes on glacier surfaces. However, the lack of seasonal observations cryoconite biota limits our knowledge glacial ecosystem functioning. We studied photoautotrophs, consumers sediment characteristics (community structure, biomass, elemental composition, organic matter content, δ13C, δ15N) from in upper lower parts Forni Glacier ablation zone (Italy) throughout season. Dominant cyanobacteria...
Abstract The methods of separation microalgae has a significant impact in the economic aspects their cultivation. In this study, pine bark was used as substrate for immobilization microalgal biomass cultivated raw municipal sewage. experiment conducted cylindrical photobioreactors (PBRs) with circulation wastewater. Biomass 42 days. After that time, abundant growth biofilm on surface well improvement quality treated sewage were observed. efficiency removal nutrients from wastewater 64–81%...
The chalcone synthase (CHS) gene controls the first step in flavonoid biosynthesis.In flax, CHS down-regulation resulted tannin accumulation and reduction lignin synthesis, but plant growth was not affected. This suggests that content thus cell wall characteristics might be modulated through activity. study investigated possibility affects sensing as well polymer arrangement. CHS-suppressed lignin-reduced plants showed significant changes expression of genes involved both synthesis...
Abstract This paper describes in detail the phenotypic traits of newly discovered Leptolyngbya sieminskae sp. n. (Cyanobacteria). The species was found at two islands Svalbard archipelago (Spitsbergen and Nordaustlandet) habitats which differed humidity, water sources altitude. research conducted fjords: on southern side Spitsbergen - Hornsund (77ºN, 015ºE) north−west Nord− austlandet Murchisonfjord (80ºN, 018ºE). Although different latitudes no significant morphological differences were...
Abstract The paper presents the results of a study cyanobacteria and green algae assemblages occurring in various tundra types determined on basis mosses vascular plants habitat conditions. research was carried out during summer years 2009-2013 north sea-coast Hornsund fjord (West Spitsbergen, Svalbard Archipelago). 58 sites were studied differing composition plants, trophy humidity. 141 noted area total. Cyanobacteria flora is significant element many sometimes even dominate there. Despite...
The process of growth algae can be described using the images from microscopic analysis. new approach to assessment dynamics used data granulometric composition liquid medium and modified Avrami equation relating crystallisation process. This paper presents a comparison both methods (granulometric microscopic) for analysis changes in wastewater. experimental set-up consisted four glass tanks filled with biologically treated sewage, which grew. cultivation was carried out 8 weeks. During this...
Abstract The article presents the research into taxonomic diversity of cyanobacteria and algae, as well relationships between these organisms habitat conditions certain water ecosystems varying in origin location (both rural urban reservoirs Lower Silesia region — Poland). Another issue addressed paper is influence ecological origins on structure phytoplankton. RDA enabled to identify most important biological parameters (the biodiversity algae described using Shannon-Weaver Index)...
The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors structure microflora communities remain largely unclear. This study was conducted Hornsund Bay, which exhibits large variability physicochemical characteristics habitats, particularly with regard to availability nitrogen phosphorus. variability, a degree, caused by seabird colonies, fertilize nutrient-poor terrestrial...
Abstract Cryoconite is a sediment occurring on glacier surfaces worldwide which reduces ice albedo and concentrates surface meltwater into small reservoirs called cryoconite holes. It consists of mineral biogenic matter, including active microorganisms. This study presents an experimental insight the influence oxygenation ability to produce decomposition organic matter. Samples were collected from five glaciers in Arctic European mainland. three was incubated stagnant mechanically mixed...
Abstract This article describes the morphological characteristics of populations green alga, Tetraspora gelatinosa, growing in stressful Arctic conditions (77°00’22” N, 015°32’54.33” E). We present first detailed this spe-cies from such a high latitude. Populations both stagnant and flowing waters were studied. Depending on type habitat, their mucilaginous colonies (thalli) have differ-ent shapes, but structure, size placement vegetative cells, akinetes ameboid forms, as well pseudocilia...
Abstract The aim of the study was to compare cyanobacterial and algal assemblages occurring in ornithocoprophilous habitats formed under influence two seabird colonies (mixed colony piscivorous Uria lomvia Rissa tridactyla planktivorous Alle alle ) nesting on southwest side Hornsund (Spitsbergen). Various influences bird ( e.g. surface trophy, treading) lead formation ornithogenic with quantitatively qualitatively diverse assemblages. Only 6 species common both were identified, but due their...
The paper describes cyanobacterial assemblages in relation to mosses and vascular plants forming mosaic communities Arctic tundra. study area is located the north of Hornsund fjord. In selected 14 type habitats, analyzed quantitative qualitative share cyanobacteria, plants. Due their similarity relations vegetation, they were divided into 10 groups. Each group was characterized by a particular combination species with distinguishing cyanobacteria dominant significant role crusts mats...
