Macrozoobenthos in tributaries of the lower reaches of the ponoy river (Kola peninsula, Russia) in the habitats of young atlantic salmon (Salmo Salar L.) and brown trout (Salmo Trutta L.)

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
The study of the composition, abundance and biomass of zoobenthos was carried out in the mouth of the tributaries of the lower reaches of the Ponoy River to determine the state of the ecosystems of the river and assess the feeding resources for salmonid ...

The changes in the profundal benthos during the extremely low water level in the deep lake Arakhley (Siberia) [PDF]

open access: yesBIO Web of Conferences
Data on the impact of long-term water level fluctuations on benthic invertebrate communities of the deep lakes in Siberia are scarce due to the rarity of such events and the short history of observations. The studies of the dynamics of zoobenthos and the

BIODIVERSITY OF ZOOBENTHOS AT THE CA RIVER, VIETNAM [PDF]

open access: yesMarine Research in Indonesia, 2008
A research on zoobenthos biodiversity was carried out from September 2004 to September 2006 at the Ca river (the length of Nghe An and Ha Tinh provinces) showed a species composition consisted of 154 species, 115 genera, 72 families, 32 orders and 5 phyla, including Mollusca, Annelida, Arthropoda, Echinodermata and Sipuncula.

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr

open access: yesJournal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

Ecological Interaction between Submerged Macrophytes and Zoobenthos

open access: yesSDRP Journal of Earth Sciences & Environmental Studies, 2017
Aquatic ecosystems are highly influenced by the interactions between submerged macrophytes and zoobenthos within the water column and the sediment underneath. This review paper discusses the complicated bilateral relationship within submerged macrophytes

Bottom-pelagic links of hydrobionts in the Kara Sea according to data on δ15N and δ13C and feeding of fish

open access: yesИзвестия ТИНРО
To compare trophic properties in pelagic and benthic communities of the Kara Sea, isotopic composition of carbon and nitrogen (δ13C and δ15N) was examined in tissues of zooplankton, zoobenthos, and fish.

Polycyclic Aromatic Hydrocarbons Have Adverse Effects on Benthic Communities in the Baltic Sea: Implications for Environmental Status Assessment

open access: yesFrontiers in Environmental Science, 2021
Changes in benthic macrofaunal communities are indicative of environmental stressors, including eutrophication and hypoxia. However, some species are sensitive not only to hypoxia but also to various environmental contaminants.

Zoobenthos of the Lednické rybníky ponds

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Qualitative and quantitative composition of macrozoobenthos was studied on the lednické rybníky ponds. Altogether 299 taxa of benthic macroinvertebrates were determined. The values of macrozoobenthos density and biomass ranged between 5–13 021 ind.m–2 and 0.02–79.6 g.m–2 respectively.

Community structure and range shifts in Arctic marine fish under climate change

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Arctic marine ecosystems are rapidly transforming due to climate change. Warming temperatures and shrinking sea ice are enabling boreal fish to expand northward, possibly disturbing cold‐adapted Arctic species assemblages. Species range shifts have been documented in the Bering and Barents Seas, raising concerns about ecosystem restructuring.
