The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, Volume 168, Issue 3, Page 1148-1158, July 2026.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

Structure and Distribution of Zoobenthos of the Kharbey Lake System [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2014
Zoobenthos communities of Bolshoy Kharbey lake system were studied in 2009-2012. Species composition and trophic structure, fauna of dominant groups (Oligochaeta, Crustacea, Chironomidae), quantitative development and distribution of bottom invertebrates

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.)

Transactions 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 ...

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to

The Aggregation of Fish in the Metalimnion Constrains Zooplankton Diel Vertical Migration

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The role of fish predation in zooplankton diel vertical migration (DVM) is well established, where zooplankton move to deep waters during the day—to hide from visual predators in surface layers—and return to the epilimnion at night (i.e., ‘normal’ DVM), to feed on phytoplankton.

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

BIO 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

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

Frontiers 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.

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

Известия 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.

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

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

Journal 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.
