The application of methods of ecosystem analysis to the evaluation of water quality [PDF]

open access: yes, 1980
Guided by experience and the theoretical development of hydrobiology, it can be considered that the main aim of water quality control should be the establishment of the rates of the self-purification process of water bodies which are capable of ...

The Quest for the Ideal Scintillator for Hybrid Phototubes

open access: yes, 2007
In this paper we present the results of extensive studies of scintillators for hybrid phototubes with luminescent screens. The results of the developments of such phototubes with a variety of scintillators are presented.

Seasonal Environmental Conditions and River Morphology Shape Summer Phytoplankton Communities

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Phytoplankton form the base of large river food webs, but there are limited studies on the nature and drivers of communities over longer time scales. Further, climate change is projected to favour taxa associated with harmful algal blooms, but our knowledge of the timing, locations and drivers of cyanobacteria in rivers lags that of lakes and ...

TRACES OF HIGH SEISMIC ACTIVITY IN THE UPPERMOST SEDIMENTS OF LAKE BAIKAL, SIBERIA

open access: yesГеодинамика и тектонофизика, 2021
Sedimentation in Lake Baikal is significantly affected by continuous seismic activity in the Baikal Rift Zone. Our study shows that historical earthquakes, as well as recent seismic events, considerably influenced sedimentation in this deep tectonic ...

Comparison between transcriptomic responses to short-term stress exposures of a common Holarctic and endemic Lake Baikal amphipods

open access: yesBMC Genomics, 2019
Background Lake Baikal is one of the oldest freshwater lakes and has constituted a stable environment for millions of years, in stark contrast to small, transient bodies of water in its immediate vicinity.

Comparative Physiology and Genomics of Thermincola and Carboxydocella Strains and Description of Two Novel Isolates

open access: yesEnvironmental Microbiology, Volume 28, Issue 3, March 2026.
Two novel thermophilic bacteria, Thermincola strain AZ34E and Carboxydocella strain AZ29I, were isolated from hydrothermal environments and shown to oxidise carbon monoxide via the water‐gas shift reaction. Comparative genomic and phylogenetic analyses revealed that all currently described isolates within Thermincola and Carboxydocella each represent a

THE DIVERSITY OF CHIRONOMIDAE IN LOTHIC AND LENTHIC ECOSYSTEMS IN PRYBAIKALIYE

open access: yesCHIRONOMUS Journal of Chironomidae Research, 2006
Taxonomic diversity of chironomid larvae in Prybaikaliye water bodies (creeks, rivers and lakes) have been studied. It is shown that Lake Baikal is a buffer zone between water catchment basin and water body. Habitat conditions in the Lake Baikal littoral

Neutrino Detection, Position Calibration and Marine Science with Acoustic Arrays in the Deep Sea

open access: yes, 2013
Arrays of acoustic receivers are an integral part of present and potential future Cherenkov neutrino telescopes in the deep sea. They measure the positions of individual detector elements which vary with time as an effect of undersea currents.

Phylogeography and Contact Zones of the Common Grass Snake in Poland (Squamata: Natricidae: Natrix natrix)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 209-219, March 2026.
ABSTRACT Until now, the genetic identity of common grass snakes (Natrix natrix) in Poland remained poorly understood. This study presents the first comprehensive phylogeographic analysis for Poland using mitochondrial DNA sequences (cyt b and ND4 + tRNAs) and 13 nuclear microsatellite loci.
