Nutrient enrichment decreased the Cross-Taxon congruence across bacteria, fungi, and zoobenthos in sediment

Ecological Indicators
Eutrophication is a major problem currently affecting sediment biodiversity in different kingdoms. Surveys at different spatial scales have suggested that nutrient enrichment drove the congruence in biodiversity across different kingdoms.

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 ...

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

Acta 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.

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.

MONITORING ZOOBENTOS PRODUCTIVITY AT THE REGULATED SURA RIVER SECTION IN PENZA REGION

Известия высших учебных заведений. Поволжский регион: Естественные науки, 2020
Background. Zoobenthos is an essential component of the fish food base. Therefore, an assessment of fish productivity for this indicator is necessary for any comprehensive fisheries research in water bodies.
