Radon Assessment in Ceratophyllum demersum Plant Samples

open access: yesIraqi Journal of Science, 2022
     The amount of radioactive isotopes in submerged Ceratophyllum demersum plants samples were estimated using passive track detector CR-39.  The samples were collected from four selected sites along the Tigris River in Baghdad city, on a monthly basis for one complete year of 2019. Certain factors like radon concentration (Bq.m-3), radium content (Bq.

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Sediment Characteristics in Stonewort Chara tomentosa Assemblages

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.

Protected Areas Have Not Halted Macrophyte Biodiversity Loss and Eutrophication in Northwest German Standing Waters

open access: yesJournal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
Since the mid‐20th century, mean site‐level macrophyte richness declined by more than a quarter across 119 standing waters of various types in northwest Germany. Within protected areas, richness was consistently higher but declined at similar rates. Communities shifted towards eutrophic‐hypertrophic indicators, underscoring the need for catchment‐wide ...

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

Ecogenotoxicity testing of aquatic environment by comet assay in plants

open access: yesFrontiers in Genetics, 2015
One of the goals of environmental monitoring is the detection of potentially hazardous compounds in water. We have set up a standard method to apply the Comet assay in aquatic plants that could be of great interest to evaluate cytotoxicity, genotoxicity ...
