Zooplankton and zoobenthos of national natural monument Pastvisko (Pasture land)

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
In the year 2002 the seasonal dynamic of zooplankton and zoobenthos in six localities of the national natural monument Pastvisko was observed. The localities belong to the lower Podyjí region, wetlands of international importance.

On the modelling of biological effects on morphology in estuaries and seas [PDF]

open access: yes, 2003
Morphological modelling aims to explain and predict the changes in rivers, seas and estuaries due to these interaction. In recent history, a lot of progress has been made, especially with stability analysis approaches.

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

open access: yesИзвестия 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.

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.

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 ...
