Water quality is an emergent property of a complex system comprised of interacting microbial populations and introduced microbial and chemical contaminants. Studies leveraging next-generation sequencing (NGS) technologies are providing new insights into the ecology of microbially mediated processes that influence fresh water quality such as algal blooms, contaminant biodegradation, and pathogen...

Levels of radionuclides in seven species of marine brown algae and Ulva were determined to establish a baseline for the Northern Pacific Ocean/Bering Sea (Aleutian Islands). There were differences in levels among algal species and locations (Amchitka Island vs Kiska Island). No values were above the minimum detectable activity (MDA) level for (137)Cs, (129)I, (60)Co, (152)Eu, (90)Sr, and (99)Tc...

The data on monitoring the vigor state of suburban pine forests metropolis Krasnoyarsk in 2021–2022 are presented. These belong to boreal Central Siberia. More than a thousand trees marked with individual numbers examined A and B annually (diameter, height state). Discoloration needles has been recorded yearly: forest since 2012 2019. Phytopathological analysis excluded influence pathogens or p...

Comparative genotype and toxin interactions at three polymorphic enzyme loci were examined in a laboratory population of amphipods (Hyalella azteca) during acute exposure to cadmium, zinc, copper, lead, or low pH. Significant toxin-genotype interactions were observed using logistic regression to model mortality in ten of 15 analyses. Both stressor-specific and nonspecific modes of selection wer...

Freshwater quality represents a central issue for human populations and the conservation of aquatic communities. In this sense, freshwater reservoirs, such as lakes, require proper management monitoring plans to avoid their deterioration pollution. Bioindicators, testate amoebae, are an excellent tool increasingly utilized limnology paleolimnology assess trophic status lacustrine environments. ...
