Trophic characteristics of zooplankton and zoobenthos in certain water masses in the western Chukchi Sea, by δ¹⁵N and δ¹³С data

Известия ТИНРО, 2023
To compare trophic characteristics for pelagic and bottom communities of zooplankton and zoobenthos in the western Chukchi Sea, isotopic composition of carbon and nitrogen (δ13С and δ15N) is determined for three different types of water masses.

Zooplankton and zoobenthos of the ponds in the Žďár region

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
In the years 1989–2000, the species composition and seasonal dynamics of zooplankton and zoobenthos in six ponds in the Žďár region were monitored. Altogether 83 taxa of water invertebrates were determined. Size and species composition of zooplankton and

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

Ecography, 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.

Diversification of Aquaculture Production in Relation to Global Change: The Case of the Domestication of Indigenous Euryhaline Catfish Species (Siluriformes) in the Mekong River Delta, Viet Nam

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT The Mekong River Delta, the heart of Vietnam's aquaculture industry, is facing many challenges due to climate change, particularly salinity intrusion. In this context, this review aimed to assess the potential of indigenous euryhaline catfish species to diversify fish farming, strengthen food security, and build resilience in the region. Among

Nutrient, carbon, and darkening impacts on coastal dissolved phosphorus bioavailability—a mesocosm study

Limnology and Oceanography, Volume 70, Issue S2, Page S183-S195, December 2025.
Abstract Coastal eutrophication results from increased riverine loads of inorganic nutrients, including phosphorus (P), which may co‐occur with increased dissolved organic carbon (DOC) loading. These DOC molecules are often pigmented, causing water darkening, but they also contain dissolved organic P (DOP), which could exacerbate eutrophication ...

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

Landscape‐Mediated Effects of Climate Change on Metacommunities Inhabiting Mediterranean Seagrass

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Climate change affects dramatically biogenic habitats by altering the geographic distribution of the foundational species and the structure of landscapes they form. As a consequence, the associated biotic communities could experience habitat loss and fragmentation.
