The work is devoted to the topical issue of assessing state and changes river ecosystems located within boundaries large cities industrial agglomerations. paper presents results obtained during hydrobiological studies on small rivers St. Petersburg (Russian Federation) in 2019-2021. application bioindication methods substantiated order assess long-term aquatic under conditions increasing anthro...

The reconstruction of human impact is pivotal in palaeoecological studies, as humans are among the most important drivers Holocene vegetation and ecosystem change. Nevertheless, separating anthropogenic footprint on dynamics from climate other environmental factors (disturbances such fire, erosion, floods, landslides, avalanches, volcanic eruptions) a challenging still largely open issue. For t...

The Burabay National Natural Park unites six lakes located among the steppe landscape, with Lake Borovoe being most visited them. phytoplankton of protected was examined in summer season 2019, at eight stations, which were defined for first time as monitoring sites on lake surface. Altogether, 72 algae and cyanobacteria species from seven taxonomic phyla found during study period. species-rich ...

The species diversity and changes in the structural dynamics of algal flora from alpine lake Nesamovyte has been studied for 100 years. During period investigations, 234 (245 infraspecific taxa) were revealed to cover more than 70% modern composition lake. biodiversity algae is characterized by an increase number widespread forms, a change baseline “montane” complex comparison beginning 20th ce...

Abstract Peatlands represent globally important habitats and carbon stores. However, human impacts climate change leave peatlands with a substantial management challenge. Degradation of peatland their hydrological integrity is increasingly counteracted through the rehabilitation including re-wetting drain blocking. Research into how such interventions affect microbial assemblages limited. Here,...

The article is focused on a hypothesis verification: the higher plants, microalgae and cyanobacteria may be used in bioindication of steppe ecosystem restoration dynamics after fires. On territory Askania Nova biosphere reserve (Ukraine) 4 stationary polygons were investigated: SP1 – area which had not been exposed to fire for 20 years preceding our study, as well areas where single fires occur...
