Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry. [PDF]

Ecol Evol
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Influence of meromixia on the distribution of zoobenthos and zooplankton in the salt soda lake Doroninskoe

IOP Conference Series: Earth and Environment, 2022
Meromictic soda lakes are considered models of reservoirs of the Early Proterozoic. Lake Doroninskoe belongs to a rare type of moderately salty alkaline soda lake with a carbonate type of salinity and pronounced meromixia. Studies and publications on the

Stress-linked morphological change associated with rearing techniques of hatchery-reliant endemic landlocked Atlantic salmon (Salmo salar m. sebago). [PDF]

J Fish Biol
Abstract Domestication effects caused by hatchery rearing impact various traits in fishes. Lake Saimaa landlocked salmon (Salmo salar m. sebago) have been dependent on hatchery propagation for over 50 years. The population is therefore at risk of hatchery‐induced phenotypes, which can be suboptimal in the wild, thus impacting the long‐term viability of

Quantitative development and structure of zoobenthos in channels on the left margin of the Selenga River delta

Limnology and Freshwater Biology, 2021
. There are only a few studies on zoobenthos in the delta of the Selenga River located at the junction of Lake Baikal and its largest tributary. The present work provides the results of research on zoobenthos in the southern (left) Selenga delta channels

Diversity of littoral zoobenthos in Lake Arakhley (Transbaikalia) during the arid phase

IOP Conference Series: Earth and Environment, 2021
There is little data available on the zoobenthos of the Baikal region’s eastern periphery water bodies in low-water years. The taxonomic diversity of zoobenthos of the littoral zone of a deep lake (Arakhley, Transbaikalia) was studied in an extremely low-

The effect of heating water on the quantitative parameters of the zoobenthos of the Lukomlskaya GRES cooling reservoir

Proceedings of the National Academy of Sciences of Belarus Biological Series, 2021
The changes abundance zoobenthos at the heated zone and non-heated zone on the different depths in summer and autumn was studying in this article. In the heated zone, the abundance was 1.5‒2 times higher than in the non-heated zone in summer and autumn ...

Differential effects of freshwater browning across fish species: consequences for individual- to community-level fish traits in north temperate lakes. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...

Sediment Characteristics in Stonewort <i>Chara Tomentosa</i> Assemblages. [PDF]

Ecol Evol
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.
