Aquatic macrophytes as indicators of heavy metal pollution of water in DTD canal system [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2003
The aim of this investigation was to establish the presence or absence of chemical contamination of water and the littoral zone (banks) of Danube-Tisza-Danube (DTD) canal system. The investigation covered the canal section from Bezdan to Prigrevica.

Refined Interpretation of the Pistillate Flower in Ceratophyllum Sheds Fresh Light on Gynoecium Evolution in Angiosperms

open access: yesFrontiers in Cell and Developmental Biology, 2022
Molecular phylogenetic analyses have revealed a superclade of mesangiosperms with five extant lineages: monocots, eudicots, magnoliids, Ceratophyllum and Chloranthaceae. Both Ceratophyllum and Chloranthaceae are ancient lineages with a long fossil record;

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 ...

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Biomass‐Derived Cu, S, and N‐Doped Biochar as a Green Electrocatalyst for CO2 Reduction to Formate and Acetate

open access: yesChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Cu, S, and N‐doped biochar electrocatalysts are prepared from waste pine needles through a green and scalable pyrolysis route. Copper loading and heteroatom doping are tuned to control structural defects and active Cu+ sites. The optimized catalyst promotes efficient CO2 adsorption and CC coupling, achieving enhanced acetate selectivity and energy ...

Quantifying aquatic plant commonness and co‐occurrence across scales to support ecological understanding and management

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Macrophyte commonness and co‐occurrence were quantified to support objective classifications of species distributions in Midwestern lakes. This framework provides a practical tool for conservation prioritization (e.g. identifying species that are rare at regional and local scales that may be more susceptible to local disturbance), invasive species risk
