The Role of Emergent Aquatic Macrophytes in Changing Water Quality at Al-Shafi Marsh, Southern Iraq

مجلة مركز بحوث التقنيات الاحيائية, 2009
This study was done at Al-Shafi marsh, southern Iraq, to determine the role of emergent aquatic macrophytes in changing the water quality. Three dominant emergent aquatic macrophytes were identified in the marsh and the vegetation cover percentages for ...

Maximal Swimming Speed Explains Differences in Habitat Use Among Invasive Ponto‐Caspian Dikerogammarus Species (Crustacea, Amphipoda)

Journal of Zoology, EarlyView.
The three invasive Ponto‐Caspian Dikerogammarus species (D. bispinosus, D. haemobaphes, and D. villosus) show niche differentiation along the current velocity gradient. In the present study, we experimentally measured their maximal swimming speeds to test whether they coincide with their tolerances for currents.

Duckweeds under salt stress: a meta‐analysis of growth inhibition in relation to morphological and physiological traits and a systematic review of molecular responses

New Phytologist, EarlyView.
Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Dietary habits of the black-necked swan Cygnus melancoryphus (Birds: Anatidae) and variability of the aquatic macrophyte cover in the Río Cruces wetland, southern Chile.

PLoS ONE, 2019
The black-necked swan Cygnus melancoryphus is an aquatic herbivorous bird whose dietary habits depend on the dominance and accessibility of macrophyte banks in shallow areas of coastal and limnetic wetlands in southern South America.

Sustainable Aquaculture Industry in Kenya: Mapping Inputs for Fish Feed, Constraints, and Opportunities for Youth Involvement

Reviews in Aquaculture, Volume 19, Issue 1, January 2027.
The cost of aquafeed continues to constrain aquaculture production amidst the availability of locally available ingredients for feed formulation and technological opportunities. Information dissemination and innovative rethinking on the utilization of local opportunities and youthful labor may spur the growth of the sector, thus improving fish protein.

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.
